How to make a pipe bender for a profile pipe with your own hands. Homemade pipe bender for a profile pipe: application, drawings, video Pipe bender for a profile pipe with your own

Profile pipes are used as a material no less often than round ones. Carrying out installation work with them, you also have to cut, bend, sharpen, and cook. Such work cannot be done without the appropriate equipment.

Buy ready-made devices It doesn’t always work out for a mechanic or plumber; you often have to make the equipment yourself. For example, make a pipe bender profile pipe Anyone can do it with their own hands. We propose to familiarize yourself with the three most popular options and the technology for their construction.

The use of a special tool that allows you to easily and simply bend pipes, including profile ones, can already be considered a plumbing tradition. Meanwhile, over the entire period of plumbing practice, a number of simplest ways to obtain bends without using a special tool have been invented.

Take a look - maybe you won’t have to build a pipe bender at all. True, it should be said that this approach is not always ready to fully satisfy the needs for bends. Especially if you need to bend a profile pipe in several places at once and under different radii.

The easiest way to bend a profile pipe efficiently and beautifully is to use special devices– pipe benders. But in some cases it is quite possible to bend profile pipes yourself

The simplest homemade methods that help you make one or two folds without using any equipment:

• filling the internal cavity of the pipe with sand;
• filling the internal cavity of the pipe with water and then freezing it;
• using a homemade mandrel;
• trimming the profile wall along the internal radius.

When there is a need to bend a profile pipe at one, or maximum two points distant from each other, it is quite reasonable to use simple methods:

1. Fill the inner area of ​​the profile pipe with fine river sand.
2. Close the end parts tightly.
3. Bend the profile with your hands according to the template in the right places.

Work with a pipe filled with water is done in the same way. But in this option, the water must be frozen. Working conditions do not always allow such a procedure.

To bend a pipe without deformation and to a given radius, it is enough to fill its internal area with ordinary river sand. This method is suitable for working with thin-walled pipes

Another similar method is to use a mandrel - a slightly smaller steel spring internal diameter the pipe itself. The spring is placed inside and then folded.

This way you can bend thin-walled pipes by hand. For profile products with a more powerful configuration, these methods are not suitable.

It is easy to bend a thick-walled profile pipe using the “undercut” method. As a tool, you can take a hacksaw or circular saw. On bent pipe the joints of the sections are sealed by welding

Thick-walled powerful profiles can be bent at one or two points using a simple method of technological undercuts. The technology involves cutting out small segments of the pipe wall along the internal radius (for example, with a grinder).

Then the profile is bent until the boundaries of the cuts made are connected. The junction points of the undercut boundaries are welded using electric welding.

When working on a site or in a garage, quite often it is necessary to bend several pipes along one or another circle. Or, as an option, make even steel strips semicircular. For this, a device such as a pipe bender is used, but purchase factory model to perform a couple of operations is not a cheap pleasure. It’s easier to make a simple pipe bender with your own hands that can bend a pipe to the required dimensions. We will get acquainted with the simplest and most popular versions of this design today.

What are pipe benders used for?

Profile pipes with various cuts are considered the most popular today metal products and are used in the construction of greenhouses, sheds, garages, for creating fences, during pipeline laying, and so on. And in the manufacture of most of these products, pipes must be bent at one angle or another, and without special equipment there is no way to cope with this.

So, a pipe bender is a special device through which, in most cases, pipes are bent, and the bending angle can be different (within 0-180 degrees). The drive of a modern pipe bender is often electromechanical or hydraulic.

Note! Using the device described in the article, you can bend products of any configuration (boiler, gas and water supply; moreover, pipes can be either steel, copper, aluminum or metal-plastic).

The scope of application of a pipe bender is quite wide - it can be found on construction sites, when creating heating/water supply networks, at industrial facilities, etc. A pipe bender made with one’s own hands is an irreplaceable thing in the household that can be used for the most various works. If, for example, you intend to install an air conditioner yourself, equip a ventilation or heating system, then it will not be easy to do without this unit.

How does a pipe bender work?

The specific design of the device depends, first of all, on its purpose, however, a pipe bender must include:

• frame;
• a pair of pipe stops;
• hydraulic cylinder;
• strips (upper/lower).

Note also that the frame can be either open or closed. As for the hydraulic cylinder, it is the main part of the device that performs the power function.

Also in the do-it-yourself pipe bender circuit there is a pressure device, which is located on the back of the body; The bypass valve screw and handle are located in the same place. But on top of the cylinder there is a plug through which oil is poured inside and its level is checked. The unit strip located below is screwed onto the thread located in front of the housing, and then pressed with a special fixing nut. Additionally, the bar is secured with a lock and a pair of screws.

For manual reinforcement, a retractable rod is used, which returns back thanks to a spring located in the cylinder. The pipe bender bars are designed as welded structure. The transverse plates have holes through which stops are installed. At the bottom of the case there are also threaded holes for mounting bolts, adjustable in height.

Note! The stop is made in the form of a pin, and the stops, which are located at its ends, are inserted into the holes on the slats. The bent product will rest on the stream located in the middle of the stop. The bending elements are made of precision cast steel.

When considering a pipe bender with your own hands, one cannot help but note the fact that profile pipes with thin walls have become increasingly popular in recent years; moreover, they make it possible to create durable and attractive designs, as well as save on costs construction work. It is from these pipes that greenhouses and various canopies are made today. What is the difference between a profile pipe and an ordinary one? First of all, the cross section, which in in this case not round, but oval, rectangular or square. This is precisely what explains the design features of a pipe bender for this type of pipe - the rollers must be of the same cross-section as the products being bent, otherwise the cross-section of the latter may be deformed.

Types of pipe benders

Using a manual pipe bender, you can bend rings and arcs. Such a device weighs relatively little (about 65 kg), thanks to which it can be transported to the work site with small metal structures (the same greenhouses, gates, canopies). Here are the main characteristics of materials that can be processed with a manual device: a round pipe with a cross-section of 3 centimeters, a square one - 4x4 centimeters, a rod - 1.6 centimeters, a strip - 4x1 centimeters and, finally, a square - 1.6x1.6 centimeters.

Thanks to various types of mandrels, the range of processed products can be expanded, and the pipe bender, in turn, can be turned into a profile bender. Price hand tools is such that it can be purchased or made with one’s own hands, even for minor productions.

As for electric pipe benders, they are used in industrial scale when working with products of various sections. Such units are very productive, which is determined, first of all, by additional functions, including rotation of rollers in two directions at once, application foot pedals, adjustment using the control panel.

The capabilities of electric pipe benders include bending arcs from square (8x4 centimeters) and round (3 centimeters) pipes. In order to match the cross-sectional configuration and diameter of the products, the devices are equipped with special replaceable mandrels for each specific case.

A hydraulic manual pipe bender is considered more modern, the strength of which is such that it allows processing fairly large steel products. It is this option that is desirable to use for water or gas pipelines. This pipe bender’s drive is equipped with a special hydraulic unit, which distinguishes it from a conventional device (the operator’s work is noticeably easier).

Hydraulic devices can be of several types at once and can be used for various pipes and fittings. Thus, a portable pipe bender (TPB) can be used for solid steel pipes, as well as for round bars ( we're talking about about the bulldozer method, when pipes are not filled with sand or other fillers). There is also a manual unit (RGU), with the help of which water and gas pipes, reinforcement or, again, rolled steel.

Note! From the point of view of operating conditions, a pipe bender (including with your own hands) can be manual or stationary. Representatives of the first group are more suitable for household use, while representatives of the second are at enterprises where bending of pipes or other products is required.

Operating principle of a pipe bender

At first it may seem that there is nothing super complicated in bending pipes, but in reality this is not entirely true. If handled incorrectly, you may encounter all sorts of defects, including crushing (which can cause a change in diameter) or stretching of the thickness at the bend (due to this, the strength characteristics of the pipeline may suffer). For this reason, the device must be selected correctly, knowing the principle of its operation - this way you minimize possible defects.

The very principle of operation is as follows. First, the required size of the semicircle is drawn on folded boards or pieces particle boards, after which they are cut along the line and fixed with nails on the floor, wall or fence. It must be remembered that this shield should be slightly thicker than the product being bent (about two to three centimeters). A stop is fixed from the edge of the board in the side part. The edge of the pipe is inserted between the latter and the template, and then a smooth bend is made in accordance with this template (for this you need to grasp the second end of the product with your hands).

Important information! If we are talking about a short pipe or a small rod, then the second end is extended by cutting a pipe that is suitable in diameter.

Also note that there are quite complex solutions to the problem of bending pipes large diameter, however, they require plumbing skills and the use of professional equipment. Making such a pipe bender yourself is not only difficult, but also expensive - it is much easier to purchase a manual unit that has already been used.

A simple pipe bender for ordinary pipes with your own hands

To assemble a simple pipe bender with your own hands, you only need what you can find at any summer cottage. More specifically, you will need:

• wooden shield;
• two small bars;
• large hooks;
• several strong boards.

Draw a semicircle on the finished shield according to which the pipe will bend. If the unit will be used several times, draw a couple of semicircles at once. Next, nail bars or boards vertically from below (they can help with inserting the pipe and fixing its ends). After this, attach large hooks along the semicircle. This unit is quite convenient, but its downside is that the hooks will have to be rebalanced each time in order to obtain different bending angles.

Making a pipe bender designed for working with profile pipes with your own hands

For this kind of pipes, the design described above is no longer suitable. For this reason, you will need a special roller pipe bender with your own hands. If you read the drawings and step-by-step instructions, you will be able to make such a machine yourself.

Materials you will need:

• pre-made frame made of steel profile;
• rollers;
• jack;
• three rollers.

After preparing everything you need, you can proceed directly to the manufacturing process.

Step one. Make a metal frame. At the bottom you can additionally weld fasteners for fixation on the countertop. After this, place a pair of vertical supports: on the side and in the center. On the opposite side (where there is no support), the profile will rise, and therefore it needs to be bolted. This part will be lifted using a jack.

Step two. Weld the shafts to the finished frame. Two are on the sides, while for the third it is necessary to prepare supports in advance. The shaft will be attached to the latter.

Step three. Weld the handle, made from a steel pipe, to the central shaft. This handle will be used to bend the product.

Step four. Fix two shafts, as well as rollers, between the shafts on the sides and the central one so that the product being bent does not move. The fact is that this way the pipe will not move much, and therefore the work will be done with the utmost care.

Step five. At the end, install a jack under the movable part of the profile (the one with the roller). The jack, by the way, can be either a simple rack or bottle jack. If necessary, secure it to the structure.

Note! Take careful measurements before starting work. Draw a diagram, check how well the parts are welded together. In addition, we recommend that you watch the video below.

Manufacturing a compact snail pipe bender

To make a pipe bender with your own hands, you can use ready-made design drawings. Check out several options, balance their complexity with your capabilities, availability of the required skills and equipment. So you can choose the most optimal design. So, check out several more options for pipe benders that you can easily assemble with your own hands.

Let's start with the fact that in order to bend profile pipes correctly, you need to clearly understand the physics of this process. As a rule, in hand tools a so-called circular bend is used, thanks to which the risks of damage to the product, cracks or creases are minimized. To bend a pipe in such a unit, you need to fix the pipe in it, and then press the lever. The product will bend as it rolls over the roller, which in turn presses it against the main wheel.

As for necessary equipment and materials, then you will need:

• sheet of metal 6 mm thick;
• ruler/tape measure;
• Working wheel;
• hammer;
• pressure roller;
• corners made of steel, with dimensions 5x5x0.25 centimeters;
• welding machine (and skills to work with it, of course);
• a piece of thick pipe with a diameter of 2.5 centimeters;
• Bulgarian;
• axes of rotation;
• washers, nuts;
• a piece of metal rod with a square cross-section (2x2x4 centimeters).

Note! When constructing a pipe bender with your own hands, be sure to follow safety requirements! This especially applies to welding and cutting metal!

How to calculate a structure. Drawing

Before you start making a pipe bender with your own hands, determine at what radius you will need to bend pipes most often. The dimensions of the impeller will depend on this (they should be the same as the inner radius of the finished elbow).

The drawing presented above was created for profile pipes whose diameter does not exceed one inch. Using this unit, it will be possible to obtain a bending radius of up to 12.5 centimeters (this is 1/2 the diameter of the impeller). But if you require other bending parameters, use the appropriate calculation method.

So, the main size of the fork is the distance between the axes of the roller and the impeller (here a = 200 millimeters). This interval was chosen in this case taking into account the fact that the maximum diameter of the profile pipe will be 25 millimeters, but we recommend adding a few more “reserve” millimeters.

Here is the formula for calculating the distance between the axes:

d + r1 + r2 + 2= a, in which:

• d is the exact diameter of the product;
• r1-2 is the radius of the roller/impeller.

Note! If the design of the future unit provides for the presence of a kind of rivulet pulley, then measure based solely on the lowest point of this element.

To determine the size of the fork, take 10 millimeters as the gap between its base and the roller, and then add another 30 “spare” millimeters. But to determine the internal clearance, add one or two millimeters to the thickness of the wheel.

Important information! For a more versatile design, make several holes on the sides of the fork. When you move the roller axis, you will change the distance between the surfaces of the rotating elements.

How to make such a pipe bender - a detailed guide

As you can see from the diagram presented above, the structure consists of:

• thick iron plate (base);
• forks;
• impeller;
• and finally the video.

To make a pipe bender with your own hands, follow the sequence of steps below.

Step one. First, make a roller and impeller. If you have lathe, this is very good, but in the absence of such equipment, these elements can also be manufactured without any difficulties. For a reasonable fee, a specialist will quickly turn your pulleys.

Note! Don't skimp on creating movable parts! They must have a groove for a pipe of maximum diameter, in addition, the roller must have a seat for a rolling bearing.

If necessary, adjustments can be made to the design of the knee surface; The roller/wheel groove is shaped. When the roller rolls, it will leave a mark on the outer surface of the knee, while the wheel will leave it on the inner surface. To make work easier and reduce the overall cost of the structure, you can install two ball bearings of the required dimensions instead of the roller.

Step two. Using the same machine, it is necessary to make an axis for the roller and impeller. It is important that the thickness of the elements matches the inner diameter of the bearing you are using. As for the length of the axle, it should be the same as the outer width of the fork. The length of the wheel rotation axis will be slightly larger, since the thickness of the base plate of the unit will also be taken into account. If you refuse to install bearings, you can thereby significantly reduce the cost of the process, and in this case the bolts will act as axes long length with nuts. Be that as it may, remember that working with such a device will be much more difficult.

Step three. After this, take a sheet of metal, cut out the back wall and side surfaces of the fork from it; in addition, you will need a piece of pipe with thick walls, which will serve as a lever.

Step four. In accordance with the diagram, make holes in the fork for the roller/wheel.

Step five. Weld the fork elements. At the same time, make sure that the right corners of this product are made especially well.

Note! It is better not to attach the lever end-to-end to the fork, since this kind of fastening will be unreliable due to the large forces applied. The best option is to drill a hole in the back wall where the end of the pipe will subsequently fit. If you weld such a joint using a welding machine, you will get an extremely strong joint as a result.

Step six. We continue to assemble the pipe bender with our own hands. So, now arm yourself with a grinder and use it to cut out the frame. After this, drill a hole in it of the appropriate size for the stationary wheel axle.

Step seven. If necessary, press the bearing into the roller.

Step eight. Place the roller in the fork and then secure it with nuts or a welding machine.

Step nine. Place the assembled fork on the base, fixing the wheel axle in the same way as when installing the roller.

Step ten. Weld a piece of square cross-section - this will be a kind of fixation of the workpiece.

Finally, make holes in the corners of the base to install the unit to the workbench. Don’t forget to clean the welding areas so that the final structure looks more attractive. Also paint the pipe bender with enamel to protect it from rusting.

Another design of a bending machine

Here, as you can see, the roller is pressed using a threaded drive. IN in this example a hydraulic jack and a manual drive will be used, in which elements of the gas distribution mechanism will be present (we are talking about those in car engines). And one more thing: do not forget about personal safety! Always use personal protective equipment when working!

Now - directly to the process of making a pipe bender with your own hands

Step one. First, make the pressure shaft and support shafts. If you do not know how to operate a lathe, you will need the help of a professional. It is important that the rollers have shanks necessary for mounting the sprockets.

Note! The chain, as well as the sprockets, can be anything.

Step two. Attach bearing supports to the shafts, secure the gears to the keys.

Step three. Weld the frame of the future pipe bender. First of all, make a square frame with support legs, and then install a structure on it, through which the plate with the roller will move.

Step four. In this case, the plate will be a channel (H- or U-shaped). To install the pressure shaft, make holes at the edges of the plate taking into account the dimensions of the bearing supports.

Step five. Hang a piece of channel with a roller on four springs on top of the frame (pre-weld nuts in the corners that will serve as mounting loops). Then finally install the hydraulic jack.

Step six. Secure the drive shafts to the lower frame.

Step seven. Place the chain on the sprockets and press down on it to determine where the tensioner will be located. Install the latter on the frame of the structure.

Step eight. Install the handle to rotate the shafts of the structure. We recommend using a handle with a rotating tube to make it easier to work and to avoid calluses on your hands.

Step nine. You can treat the finished pipe bender with your own hands with a special rust converter and then paint it.

In the end, all that remains is to check the resulting design for functionality. That's all, we hope that by following our instructions you will definitely get the desired result! And at the end - another thematic video material.

Good luck with your work!

Video - Making a simple pipe bender

When working with pipes, there is often a need to change the shape of the pipe, in other words, to bend it. This can be done at special equipment, or even buy a product ready-made form. But it is much easier and cheaper to make a simple pipe bender with your own hands. Using such a simple tool will greatly facilitate and speed up your work.

Homemade pipe bender device

The simplest design

Anyone can make the simplest manual pipe bender with their own hands. To make such a basic device, it is enough to have a concrete slab, a drill for working with concrete and steel pins (you need a lot of them).

You can make a homemade manual pipe bender without any drawings and in just three steps:

1. A square grid with cell sides measuring 4 by 4 or 5 by 5 cm is drawn on a concrete slab.
2. In the nodes of the mesh, holes are drilled for metal rods using an appropriate drill (if possible, they need to be deepened as much as possible).
3. At the end of the operation, steel rods are driven into the workpiece.

The process of creating a pipe bender for a profile pipe with your own hands includes several steps:

1. On on a reliable basis a wide channel or a series of channels is installed until the desired width is achieved.
2. A frame is mounted in the shape of the letter P, and a hole is drilled on the crossbar for the clamp coupling.
3. Two rollers are installed at an equal distance from the frame. The sprockets of the chain drive, driven by a manual drive, are attached to the rollers.
4. The third roller is attached to a pin fixed in the clamp coupling. A handle is welded to the top of the stud.

You need to bend the profile pipe on the resulting product following the sequence of actions:

• a section of profile pipe of the required length is installed on the feed rollers;
• during the rotation of the clamp handle, the product is pressed against the lower rollers using a third pin fixed at the lower end of the pin;
• Using a chain drive connected to the rollers, the profile pipe is moved through the deformation zone. Read also: "".

Electric hydraulic pipe bender

This device is characterized by greater productivity than the design described above, due to the replacement of the clamp with a hydraulic unit and the chain transmission of the feed rollers to an electric drive. Electrification eliminates the tedious self made and significantly speed up the process.

Creating an electrified pipe bending machine with your own hands occurs in the following sequence:

• The feed shaft is mounted on a flat surface.
• A pulley is attached to the end of the shaft for a belt drive that goes to the rotor electric motor. The drive sprocket of the chain drive is installed at the second end.
• At the required distance from the first shaft, a second one is installed, on which the driven sprocket is attached. It should be noted that if instead of ball bearings on the sides, steel plates in the shape of a trapezoid are welded to the base, you can use ordinary rope rollers rather than shafts as the driving mechanism.
• Mount the deforming roller - from above or below, in the corresponding hole. The roller shaft is located in the grooves of the plates or U-shaped frame. The movement of the roller is limited by the piston rod and the pipe section itself.

Bending pipes without using a pipe bender

If a one-time operation is planned or it is not possible to collect necessary design, you can bend the pipe round section and without the use of special settings.

To do this, a blank is cut out of wood, the shape of which corresponds to the planned radius of curvature finished product. The pipe is bent in clamps against the workpiece. It is also possible to replace such a template with ones driven into wooden stand pins or hooks arranged according to the principle of the first pipe bender described in the article.

You can also preheat the sand-filled pipe bending area or, if the work is done in the cold, fill it with water. After the sand is heated or the water hardens, the pipe is also bent around a template of the appropriate curvature.

Another way is to make cuts of the appropriate width in the pipe at the site of the future internal radius, then bend the pipe (the edges of the cuts should align) and restore the integrity of the pipe using electric welding. Using this technology, pipes of any size and in any direction can be bent.

In construction there is often a need to bend metal strips or pipes. If it is not possible to visit workshops that specialize in this issue, make a pipe bender for a profile pipe with your own hands. Having a similar tool at hand, it is easy to make trellises, arches for climbing plants and grapes. It will also help in the manufacture of gazebos, canopies, extensions or greenhouses, fences and even metal frames for furniture.

What does a pipe bender look like?

A pipe bender is a special device that helps smoothly deform pipes made of steel, aluminum, copper, polyvinyl chloride and other materials. The bend is made from 0 to 180˚ if the diameter ranges from 5 to 1220 mm.

The pipe bender forms the product without damage or kinks.

Based on the installation method, a distinction is made between stationary and portable devices.

By type of drive - manual, electric and hydraulic.

Pipe bender for working with pipes and metal strips

Reliable lever or screw device

The device consists of three shafts. There are two support rollers in a static position on the frame. They are rotated by a handle mounted on the neck of one of them. The material feeding shafts move uniformly thanks to the connecting chain.

A pressure roller is installed in the guides. The screw raises the guides and lowers them in a vertical rigid frame. As you can see, the diagram of a pipe bender for a profile pipe with your own hands is simple.

The first stage in the manufacture of such a device is the formation of the frame. To do this you need to take the corners. You will also need a double-row chain and sprockets. To make a handle that rotates the shafts, a calibrated rod and wrench. For further use, a cut is put on the handle. This is done to prevent calluses from appearing on your hands.

The shafts will have to be ordered from a turner. To prevent the material from sliding to the side along the pipe bender, a special groove is made in the device according to the size of the profile (+ 2 mm). The journals are forced out on the shafts to accommodate the working bearing and sprockets. In addition, you will also need keyways under the mount. The size of the groove on the gear determines its width. The depth will be equal to half the height of the key used on the car for the same sprockets.

Rollers between which the pipe passes

To prevent the screw of the device from being worn out during operation, a copper or cast iron plate is fixed to it.

For high-quality bending, the pipe is placed on the feed rollers and carefully pressed. After this, the starting point of the radius is determined. It coincides with the center of the roll located on top. The handle is rotated in the required direction, while moving the pipe using feed rollers. At each pass, stops are made during which the screw is turned and the radius is checked.

When we do profile pipe bender pipes with our own hands, we carry out modernization. In order not to rotate the heavy handle, it is enough to make a drive.

Some profile benders use adjustable rollers to bend pipes.

Instead of a handle, a pulley is installed. For good rotation, it is better to use a V-belt drive. If overloads begin in the network, it will not break, but will simply stall.

The electric motor can be taken from the old one washing machine or from the pump.

By making 5-6 shaped cuts in the feed rollers, repeating the cross-section configuration, you can achieve the versatility of the device. This tool will bend not only profile pipes of various sections, but also water pipes and metal strips. The technology for making a pipe bender for a profile pipe with your own hands is similar to one standard size, only the drawings of the feed roller barrel differ.

Lever pipe bender diagram

We make one-time pipe benders

If there is no need for permanent job device, it can be simplified. From boards that are larger than the profile, we make a bending template. The finished configuration is fixed on the shield. Initially, a clamp is nailed to hold the object, then strips are attached in several places (they protrude beyond the edge of the shield and limit the rotation of the profile).

After installation, the end is inserted between the clamp and the template and gradually pressed against the surface. A rod lever can help with this.

It turns out to be an excellent pipe bender for a profile pipe with your own hands, the dimensions of which can be any.

Diagram of a pipe bender you can make yourself

For this, a hardwood tree is selected. Oak or regular pear will do. Formation wooden elements performed on a home machine: attached to the rotating part wooden block, and with a wood cutter it is given the desired shape. It is important to use the lever carefully. We perform rotating movements smoothly, without jerking.

Pipes small size plastic and soft, therefore wooden structure bends up to ten profiles.

If there is no chain, we help move objects between the rollers ourselves. They need to be pushed by hand along the axis. Press with the end wide board, which has pre-rounded corners.

When making a pipe bender for a profile pipe with your own hands, it is important to understand main principle his works. It consists in the fact that the device deforms parts using three points, which are located at a distance of 200-300 mm from each other. During movement, they limit the rotation of the object. Thanks to this, the profile will retain its cross-section, and the surface will remain smooth and undamaged.

Bending a pipe using a wooden template

Two pipe design

For such a tool you will need two pieces of steel. Their diameter should not go beyond 70-150 mm. The sections are concreted in a vertical position. This could be a hole in the ground or a container that is no longer in active use. You can take a tall bucket, basin or plastic barrel. The main thing is that the distance between the tubes is 40-50 cm.

If it is not possible to concrete the pipes, they are welded welding machine to a reinforced base. As you can see, a manual pipe bender for a profile pipe, made by yourself, is a simple design.

The workflow itself is also simple. The bending pipe is inserted at one end into the gap between the previously installed steel sections. After this, it bends at the desired angle. This method Suitable for 40mm diameter.

To bend a pipe that is too short, fittings are inserted into it and then the work process is continued.

Pipe bender with chain and sprockets

Heated pipe bender

Thanks to this method, the bend is smooth.

The essence of the process is that selected, sifted quartz sand. It does not stick to the walls, but when hot it acts on them. The pipe is closed on both sides with wooden plugs.

It should be noted that during the heating process in closed space gases and vapors accumulate. To ensure they come out unhindered, small holes are made at the end.

The bending area is marked with chalk. To deform the pipe by 90°, a section equal to six diameters is heated (respectively, 45° is three diameters, 60° is four).

After heating, the pipe is carefully inserted into a self-made profile pipe bender and bent according to the template. Drawings of such a device can be found for free.

You shouldn’t stop in the face of difficulties; the problem can be solved if you approach it creatively. Of course, it is better to turn to experienced craftsmen, but when there is no time to wait for workers to arrive or there are no additional funds to pay for their labor, you can bend the parts yourself.

Video instructions for making a pipe bender

When installing most metal structures, bending of pipes is required different angles. A ready-made device for this can be bought at hardware stores, but what if it is unlikely to be useful anymore? Is it worth spending money on a mechanism if it will later gather dust on a workshop shelf? The simplest and most logical solution is to build the device yourself. How to make a pipe bender for a profile pipe? Recommendations experienced craftsmen and video instructions in this article.

A self-made device will help you give the product any shape.

Rolled metal, bent at a certain angle, is necessary in many structures. Among them:

• engineering communications in residential buildings: water supply, sewerage, ventilation;
• fencing around the perimeter of the site;
• home and garden furniture;
• greenhouses;
• gazebos and canopies.

You can bend any rolled metal, the main thing is to use the right tool for this purpose. Give the required form Not only steel structures can be bent; metal-plastic, copper, and aluminum can be bent.

Helpful information! To select a pipe bender, you need to take into account not only the cross-section of the product, but also its profile. Simple round pipes can be bent much easier than profile ones. If handled incorrectly, the latter can become significantly deformed or even break.

To use the tool correctly, you need to carefully study the advice of professionals in the video. A do-it-yourself pipe bender for a profile pipe can be made in a simple, manual version or using hydraulics.

Hydraulic devices quickly and efficiently bend any metal parts.

A conventional front pipe bender consists of the following elements:

• three metal shafts;
• drive chains;
• rotating axis;
• rotary mechanism;
• frames made of metal profile.

Sometimes the shafts are made of wood or plastic, but it is worth taking into account that such rollers will not cope with any pipe. If you do not calculate the resistance of the material, the shafts may simply collapse.

How does the profile bending device work?

Before you start making a homemade pipe bender for round pipe or profile, you need to understand the operating principle of the device. The action of the mechanism is based on rolling or rolling. This principle helps eliminate the risk of accidentally deforming and breaking the material. To give the metal the desired shape, it is inserted between the shafts and the handle of the device is turned. The result should be the desired bend.

Do-it-yourself pipe bender for a profile pipe: types of devices

The devices differ in purpose. There are devices for forming turns on steel, metal-plastic, copper, and aluminum products.

Devices can be portable or stationary. Portable models are convenient because they can be installed directly in the room where communications are being installed. Stationary machines used in production.

Note! Improper use of the machine can lead to changes in the internal diameter of the pipes, wrinkles of the surface and changes in wall thickness.

Manual pipe bender

Soft materials, metal-plastic and copper, bend easily manual device. Its design is quite primitive. The bender itself does not take up much space and can easily fit in a small workshop. In addition to the pipes themselves, you can bend reinforcement or rolled metal on it.

Hydraulic device

This device is capable of giving the required form material with diameters up to four inches. The profile material, using hydraulics, can make intricate bends, repeating the topography of the wall.

Making a pipe bender with your own hands for a profile pipe: drawings and diagrams

The simplest device consists of a frame, slats, and two stops. If necessary, a hydraulic system can be added to it. IN complex structures a power supercharger and additional levers are used.

An example of a diagram of pipe benders for a profile pipe with your own hands:

Helpful information! Metal parts of the structure must be thoroughly lubricated to protect against rust. You can even provide a special compartment for automatic lubricant supply.

Model No. 1 – rolling

Assembly algorithm:

• The metal base must be secured to a flat, durable surface and holes must be drilled at the ends.
• The steel rectangular plates must also be drilled to secure the rollers.
• Secure the plates to the base with nuts and bolts.
• Install rollers in the grooves the right size and fix them firmly.
• In the center of the base, weld the stands for the central shaft and secure it with a stud and nut.
• Provide one shaft with a handle for turning.

Result: You should get a design like in the photo. You can not use a metal base, but attach the plates directly to the base.

Model No. 2

Another pipe bender for a profile pipe with your own hands, of a simpler design, will cope with products with a cross-section of two and a half centimeters.

Work order:

• It is necessary to make a device template on paper.
• From scraps of lumber, assemble the device according to the template, fastening the parts with self-tapping screws.
• Screw the resulting module to the wall. Screw a beam onto one side of the module for support.

Advice! When screwing parts, you need to focus on the diameter of the pipe. It should be easy to insert and lock into place.

Model No. 3

This version of a do-it-yourself pipe bender for a profile pipe is even simpler:

• A sheet of plywood is screwed to the wall, and the desired bend is depicted on it.
• Metal hooks are secured along the line with screws. Metal plates must be attached to each hook; they will additionally secure the material being bent.
• It is necessary to provide a stop for the end of the pipe.

Advice! If you don’t have enough strength to manually perform the desired bend, you can use a winch.

Result:

Application of hydraulics

For hydraulic device you will need:

• rollers – 2 pieces;
• hydraulic jack;
• shoe;
• channel;
• steel plates.

The jack is fixed on the workbench. It will push the pipe into tight gripping rollers. If you prepare the videos different diameters, you can work with products of any size.

Video: do-it-yourself manual pipe bender for a profile pipe

To construct a pipe bending device, you can use ready-made drawings. Video “How to make it yourself for a profile pipe bender" will reflect the manufacturing procedure and the method of using the resulting tool.

• For bending, rolled metal must be heated, especially with outside diameter

• To prevent deformation, the pipe must be filled with sand before bending.

• If you are not sure of the result, don’t try it. Sometimes it is easier to buy ready-made bends and weld them to the pipe than to correctly give it the desired shape.

Drawing conclusions

It is quite possible to make a simple device for bending rolled metal with your own hands. If you need to manufacture a complex configuration metal structure, it is better to use the rolling method. For a couple of simple bends, a device using hooks is suitable.

It is worth remembering that the wrong ratio of force and excessive haste can lead to irreparable deformation of the material.
