Drawings of a pipe bender for a round pipe. How to deepen a well with a plastic pipe

home

Systems

For various reasons - as a result of wear and tear, changes in the groundwater channel - there is a need to repair the well. Repairs can be made with plastic pipes.

Which plastic pipes to choose for a well

Low pressure polyethylene pipes

Polyethylene is a polymer inert to exposure environment at low temperatures: does not release anything and does not react. It is durable and can withstand external pressure. Polyethylene pipes are ideal for cold water. Can be used to deepen wells.

Products made of polyvinyl chloride

Material Features:

significant rigidity compared to polyethylene pipes;
resistance to deformation;
impact resistance.

The non-plasticity of polyvinyl chloride does not allow its use in the ground under conditions of soil mobility. In addition, this material cannot be used at subzero temperatures.

Advantages of plastic casing pipe

Plastic casing made from polyethylene produced in low pressure, for the purpose of deepening the well, it must be corrugated with a sinusoidal surface. This structure allows the pipe to carry significant loads resulting from the movement of soil and water.

There are different types of plastic pipes, including large diameter and length. Advantage plastic type pipes for humans, in addition, is the relative ease of manipulation due to its low weight.

How to deepen a well for drinking water with your own hands

Well shaft preparation

Groundwater may be characterized by instability of its flowing volume and channel. In addition to known seasonal variations, the behavior of groundwater can change for no apparent reason. On the other hand, deepening wells is a costly and labor-intensive process. It happens that water returns after some time as unexpectedly as it disappears. You should wait within a month. If water does not appear, and there are no signs that this may happen, you can begin to deepen the well.

First, let's prepare necessary tools. We will need:

sump pump;
ladder ( best option– rope);
lamps for lighting;
shovel;
bumper;
several buckets;
a winch or a self-designed mechanism to facilitate soil lifting;
strong ropes: for insurance and for lifting buckets of soil.

Special clothing is required for the person who will perform work inside the well: long rubber boots, construction helmet, rubber gloves. Stages preparatory work:

Filming decorative elements and a shaft with which the bucket is lowered.
We fasten the concrete rings to each other. The structure must be a complete pipe for further settlement during the digging process.
Pumping out water. To save energy, we use a pump. If there is not much water, you can scoop it out with a bucket: the speed of scooping, lifting the bucket up and returning it back must exceed the speed of water entering the well.
After the water has been pumped out, it is necessary to clean the bottom of accumulated dirt, silt and sand. Cleaning is done mechanically using a shovel. We lift everything unnecessary to the top using a bucket.
We also clean the walls of the mine from moss and other growths. It is better to do this before digging, so that contaminants can be removed before water enters.

Undermining

Next comes the deepening of the well: the soil is dug out and removed from the shaft. Ideally, digging is done along the diameter of an existing concrete structure. As a result, the fastened rings should fall down under their own weight. It is necessary to add concrete segments on top according to the amount that has settled. However, spontaneous lowering may not occur: often the ground holds the concrete segments very tightly, or, for example, the shaft may run at a slight angle. In these cases, the bottom of the well is strengthened using plastic pipes smaller diameter.

In practice, digging is often done with a diameter smaller than the main well. This way you can protect yourself from possible consequences improper or too slow digging, which, as a result of subsequent settlement, can lead to deformation of concrete parts and even to their destruction. Thus, it is safer to dig within the diameter of the plastic pipe that is supposed to make the deepening.

After excavation, i.e. Once groundwater is detected, the entire structure is strengthened. If subsidence has occurred, the new and old parts of the concrete pipe are connected with screws in several places.

How to make a filter for a large diameter plastic pipe

A plastic pipe has a great advantage: it allows you to construct a filter to clean the water entering the pipe. You will need a material called geotextile, which is used to filter water and separate soils. Dutch-made geotextiles are considered the most technologically advanced - in the Netherlands, issues of water and soil are extremely acute, which has made their production the most competitive.

There are several types of geotextiles on the market designed to perform different functions. For our purposes of groundwater filtration, a needle-punched non-woven hydrophilic option would be optimal. It is this that does not become clogged with clay particles and sand, which are often present in our groundwater. Filter for plastic pipe - two layers of geotextile.
Vlad Zhitin, expert

You can use other, budget-friendly options for materials. For example, stainless steel sheets, which deposit impurity particles and prevent them from penetrating inside.

Installation of a plastic stocking

Plastic stocking is a method of wrapping one end of a pipe to ensure further filtration of water. Let us remind you: pipes that are used as a shaft or part of a well shaft are corrugated. In the depressions of the corrugation, it is necessary to drill holes along the entire plane of the pipe with a 6-8 mm drill at an arbitrary distance from each other, for example, 5 cm. The height over which the depressions are drilled will depend on the depression made and the intensity of the arrival of water. On average - 50 cm, but it is better to take it with a reserve.

Next, the drilled part of the pipe is tightly wrapped in two layers of geotextile, including covering the gap at the end of the pipe with the material. After which the material is fixed flexible insulated wire or wire. It is important that there is a layer of plastic insulation on the outside, which will prevent the oxidation of iron.

Preventative work in the well

A well that has been in use for a long time needs to be repaired. Special attention should be paid to the seams between the segments through which the earth and accompanying debris, sediment, and insects enter. The seams are sealed with cement mortar.

It doesn't hurt to pay attention to disinfection. The simplest method is bleach.

200 mg of lime is diluted in 1 liter of cold water. The settled sediment is removed, and the walls of the well are wiped with the remaining liquid.
After disinfecting the walls, the chlorine solution must be washed off with a stream of water.
Next, we make a new solution with a similar concentration and pour it directly into the water. Mix with a pole. The well is closed for 12 hours and the water is not used.
The next day, all the water needs to be pumped out. Next, we wait for the well to be filled with new water - we pump it out again. We repeat the procedure until the smell of chlorine becomes invisible and the water becomes potable.

Possible difficulties when deepening a well

Quicksand

Quicksand is a type of soil represented by fine sand (silt, clay) and water. It is unstable and mobile, does not allow itself to be dug out and passed to the next layer of dense soil. Quicksands are divided into: true (rarely found), and false or pseudo quicksands (most of them). Most correct recommendation For both types, work performed by unskilled people will stop digging. Pseudo-floats allow the water to remain at a level of 0.5-1.5 m - such wells can be used for their intended purpose. True quicksand does not give up water - such wells are not suitable.

Replacing concrete rings

Replacing rings - element overhaul well, which is used when there is significant destruction of previously installed blocks. Due to the significant weight of the ring, it is almost impossible to lift it alone, so you should provide lifting device or technology. It is important to follow safety precautions when replacing rings to avoid accidents. If the concrete rings are severely damaged, you will need to pull them out of the well in parts and clean the bottom and hole of debris.

Manual well drilling

Drilling a well is a possible alternative to completely excavating soil from wells to the aquifer. Drilling is carried out using a temporary casing through which the drill passes the soil. Theoretically, you can drill a well up to 30 m with your own hands.

Deepening a well with your own hands is a task accessible to any owner, with the right approach to its implementation. How do you extend the life of your source? How else can you deepen a well without resorting to expensive materials and use of technology? Share in the comments!

Owners country houses or personal plots, when updating a pipeline or carrying out any construction work, robots are often faced with the need to bend a round or profile pipe at a certain angle.

If such a process has to be carried out frequently, what is better to purchase special equipment. But if such a need arises rarely, then using simple manipulations you can make pipe benders for round pipe do it yourself, video tutorials and drawings of this design will be presented in the article below.

In this publication we will talk about how to make a pipe bender at home from improvised means for bending round and profile pipes. However, before starting the description step-by-step production, in the introductory part, let's look at what this tool is and for what purposes it is used on the farm.

What is a pipe bender and what is it for?

It is a design that makes it possible to bend profile or round pipe materials at the desired angle. They are divided into:

- hydraulic;

- mechanical;

- manual.

The first type copes with bending large sizes, mechanical models are used for medium-sized ones, and manual ones are considered ideal option for diameters up to 3 cm and profiles up to 4 cm.

According to their own design features, functionality and operating principle they are divided into:

- crossbow;

- segmental;

- spring.

The operating technology of any pipe bender is the ability to correctly bend the product to the required radius. If special attention is not paid to the quality of the result when bending, then homemade structures will cope with this task 100%.

Made from a metal pipe and nut

This type of bending device is considered the most elementary. It is made from a piece of rigid round pipe (metal rod) with a nut attached at the base.

We make a template for the future bend from wire;
We take measurements of the template and transfer them to the pipe;
The pipe is installed on a flat floor with a hard surface;
The pipe is inserted into the pipe bender nut, comparing its direction with the measurements on the pipe;
With your foot, resting on the pipe that is on the floor, we press it harder, and bend the second edge, slowly pulling the handle of the pipe bender towards you. Such manipulations allow it to be bent by 10˚.
Moving the pipe along the hole of the nut, the procedure is repeated several times until the bend eventually takes the desired shape.

Wood pipe bender

To bend a round pipe yourself, you can make a pipe bender from wood with your own hands. From a technical point of view, such a device is the simplest; operation does not require additional parts, such as a hydraulic cylinder.

We start by knocking together several boards of dense wood and cutting out half a circle of the appropriate diameter. For cutting, you can use the simplest hand saw, the main thing is to ensure that the slope is maintained closer to the base.

The resulting workpiece is attached to a solid base in the form of a tabletop or wall. An additional block of wood is also attached to the base to create additional support.

When choosing a tree, pay attention to the fact that its thickness must be greater than the diameter of the pipe, otherwise during the process of bending the sample, it may slip and cause injury.

To easily make a wooden pipe bender for a round pipe with your own hands, you can familiarize yourself with the video lessons below. This will help you understand all the nuances of this process.

How to work with it?

We place the pipe in the recess between the wooden semicircle and the thrust block and carefully begin to press on it with reverse side, bending to the desired shape.

The main thing is that it fits easily into the opening. This wooden device bends aluminum and steel products well. Moreover, its production requires minimal costs.

Pipe bender made of metal hooks

To make it you will need to carry out the following simple steps:

buy high-quality metal hooks at any hardware store;
we fasten them on a stable base in increments of no more than 5 cm. However, the distance of one hook from the other will depend on the size of the product that needs to be bent;
as a result we get a semicircular template;
An additional stop is attached to one side of the device.

The bending process will resemble working with a wooden template, but in this case it is not worth it different diameters To make a new template, simply move the distance between the hooks.

Pipe bender made of cylinder and rollers

Video 3. Do it yourself

It consists of rollers and a cylinder and is a more complex unit. But it allows bending at any angle up to 360˚. In fact, it is possible to create a pipe bender for a profile pipe with your own hands, as similar as possible to technical specifications, for hydraulic equipment.

The sample is fixed using rollers, and a freely moving cylinder gently bends it until desired angle. To make such a unit with your own hands you will need:

two steel plates 30 cm long and no more than 10 millimeters thick;
four steel corners with shelves measuring 5x5 cm;
a template is knocked out of wooden boards, the thickness of which should not exceed 3 cm;
the steel plate is attached to the underside of the wooden template;
on the base, in order to give greater strength to the structure, it is advisable to attach corners;
a second steel plate is attached to the top;
in the latter a hole is made of the same diameter as the screw that will be installed there;
the bolt serves as a support for the bent pipe;
Angles and rollers are attached to the top plate, which are oriented inside the pipe bender;

This type of design makes it possible to bend any profile product at any angle.

Rules for using homemade manual pipe benders

In order for the manufactured device to perform its job efficiently and correctly, you need to adhere to several simple rules on its operation.

Purchasing pipe benders for round pipes is not a problem with the current assortment. But if you need the tool solely for home use, it makes no sense to buy industrial and factory machines. It is more economical and easier to make a homemade unit.

To make an effective pipe bender for round pipes with your own hands, you need to have at least a minimal theoretical base.

The pipe bender differs in the type of drive used.

Hydraulic. The most common type of pipe bender is a hydraulic one. In this case, the machine can be homemade or factory-made. Making a good hydraulic unit with your own hands is not a problem. To do this you will need hydraulic jack. This option is good because it makes it possible to bend round pipes that have decent parameters.
Mechanical. A less powerful homemade version of a pipe bender. With its help, you can bend medium-sized products.
Manual. Manual drive is the most common in household. Almost everyone homemade machine It has a manual drive.
Electric. These are factory-made units. You can make it yourself, but you will need appropriate drawings, certain skills, an electric motor and a number of other components.

If you need to bend round pipes with a diameter of up to 30 millimeters or profile pipes up to 40 millimeters, manual machine will be the optimal solution. For more serious tasks, it makes sense to make a hydraulic pipe bender.

Options for homemade machines

To get a pipe bender for a round pipe, it is not at all necessary to spend a lot of money on buying a factory machine.

You can make a manual or hydraulic unit with your own hands. There are various drawings, from the simplest to quite complex. But we offer you exactly the simplest drawings, which allow you to get a full-fledged manual bender for round pipes in a short time.

Consider the following structures, assembled from:

Nuts and metal tube;
Trees;
Kryuchkov;
Cylinder and rollers.

Let's start with the simplest ones and end with a machine whose technical capabilities are reminiscent of a hydraulic pipe bender.

Nuts and pipes

Elementary example manual installation for bending round pipes. Here, a special drawing is not required, since the machine is made by hand from two elements.

You will need a strong metal pipe or rod. The handle should not deform when you apply force to bend it.
A nut is fixed at the end of the rod. In this case, the nut should be selected so that its internal diameter is 25-30 centimeters larger than the diameter of the round pipe being bent.
This homemade machine can handle pipes with a diameter of up to 30 millimeters.
The connection between the rod and the nut can be done by welding. Another variant - threaded connection. It's more difficult to implement, but then you can change the size of the nuts. To do this, a small piece of threaded steel is welded to the nut. The handle is also provided with appropriate rifling for threading.
The bent pipe is placed on the floor. You rest your foot on one end of the pipe, and grab the other with a nut. Gradually move the handle towards you, causing a 10-degree bend with your hands. Bend until you get the bend you want.

Made of wood

Another example of a simple DIY pipe bender for round-shaped products. A lot of auxiliary parts are not used here, so the drawing turns out to be elementary.

Cut a semicircle of the required diameter from the board. You can make several of these elements if you need to bend pipes with different parameters;
The width of the area on which the pipe is laid must exceed the dimensions of the pipe itself. Otherwise, the product may break off and cause injury;
The template board is mounted on a wall or table;
Near the board, you can install another stop made of metal or wood, where the bent pipe can rest;
You can make such a template from a single board or connect several boards together. It all depends on what angle of bend you need.

Based on the drawings and watching photos, video instructions, assembling a homemade pipe bender from wood will not be difficult.

From hooks

A good option for a machine. You don't need a drawing, but be sure to strictly follow the dimensions.

Mark the table where the hooks will be fixed for their fastening.
The hooks themselves are available at any hardware store. Choose those that are made of high-quality metal. Otherwise, your pipe will simply break them.
Attach the hooks to the base. The pitch should be no more than 50 mm. By fixing the hooks, you set a certain radius. The distance between the elements directly depends on the parameters of the round pipe.
A blank is inserted into the resulting template.
As in the first case, it is advisable to install an additional stop at the edges that is stronger than the hook.
The advantage of the design is that you can easily bend the pipe with your own hands. Moreover, for different pipes you don't have to make different templates. It is enough to remove the hook and move it to another point in order to decrease or increase the angle.

Each of the machines presented above is easy to assemble with your own hands. If you need a more serious unit that resembles a hydraulic machine, consider another option.

From rollers and cylinder

This is not a hydraulic unit, but similar in technical capabilities on a hydraulic machine. It can be used to bend round pipes of larger cross-section. An indispensable device for repairs and construction, when you don’t want to spend money on buying factory units.

The price of a finished manual pipe bender can range from 4-5 thousand rubles. A hydraulic one will cost several times more. Therefore, for many it is easier to build something similar with their own hands.

To assemble the pipe bender you will need cylinders and rollers. This machine bends pipes at an angle of up to 360 degrees, which is very serious.
Grab a pair metal plates. Their length and thickness are 30 cm and no more than 10 mm, respectively.
Also buy four steel corners with shelves. Their size is about 5 by 5 cm.
Using wooden boards, assemble the template. Its thickness is about 30 millimeters, no more.
Connect the steel plate to the underside of the board template.
To increase strength, corners are fixed to the base.
A second high-strength steel plate is mounted on top of the template. A hole is made in it in accordance with the size of the screw that will be used for installation. It is the bolt that will be the stop, so choose a durable element.
Install angles and rollers on the top plate. The rollers should be oriented towards the inside of your machine.
The fixed cylinder and freely moving rollers allow pipe bending work to be carried out.

Although this model is more intended for profile pipes, it is quite possible to adapt it to bend a round pipe.

These are just a few options on how you can create a full-fledged pipe bender with your own hands.

When performing home construction or plumbing work, it often becomes necessary to bend a metal pipe to a different radius.

It is necessary to bend round pipes when laying water supply networks or heating systems. If you try to bend the workpiece against a rectangular stop, a crease will appear and the pipe may simply burst.

In addition, if bending is incorrect, it decreases internal section, which negatively affects fluid permeability.

You can bend a round pipe efficiently using a special device - a pipe bender.

The purchase of industrial tools is justified only for craftsmen who bend pipes professionally on a commercial scale. The cost of this device is quite high. Therefore, most home craftsmen make for one-time work.

There are not many ways to bend a pipe. Before you decide what type of tool you need, let's look at their types, advantages and disadvantages.

IMPORTANT! When working with such a tool, a lot of force is applied. Therefore, it is necessary to avoid injury.

What types of pipe benders are there based on their operating principle?

Break-in

The beginning of the pipe is fixed close to the stationary template. Using a pressure roller, the pipe wraps around the template and takes its shape.

Advantages - such a device is easy to make, it takes up little space, and can be easily mounted on a workbench or simply on the garage wall.

Disadvantage – bend radius equal to diameter template. This can be partially solved by changing the central node.

Winding

The template is movable, the pressure roller is not.

The workpiece is fixed on the template using a bracket or other device, the template rotates and, using a clamp, the pipe bends. During operation, the part is wound onto a central pulley, hence the name.

The advantages are, again, simplicity of design.

Disadvantages - restrictions associated with the size of the template; a powerful lever and bearing for the drive are required.

Crossbow

The pipe is installed on two fixed supports. Strictly in the middle, a shoe (punch) of a certain radius presses on the bend.

Hydraulics or a screw drive are used as a source of force. The workpiece bends like the string of a bow or crossbow. Hence the name.

Advantages - relative mechanization of the process, less physical effort required. Easy change of punches makes the tool more versatile.

Disadvantages - Limited bend radius. Larger sizes will require a bulky mechanism and massive shoes. At the points of application of force (both on the supports and on the punch), deformations of the pipe walls occur. A thin-walled workpiece may simply burst.

Rolling (rolling)

The pipe is installed between three rollers, the central one of which can move in height relative to the support ones.

Popular: Homemade pipe bender how to make it at home

Disadvantages - large dimensions of the structure, it is inconvenient to work with small radii. In addition to bending methods, it is necessary to know the mechanical limitations for pipes various diameters and wall thickness. As an example, we give a table of bending radii that are safe for the material. It's about O steel pipes ah, there are different standards for aluminum or copper. If it is necessary to make a bend of a smaller diameter, the pipe must be heated. IN industrial conditions, hot rolled steel is used. In household - gas-burner. IMPORTANT! The use of open flames on wooden tools and workbenches is prohibited.

Homemade pipe bending devices

Simple wooden pipe bender

The design is of the break-in type. Only the pinch roller is not used. To make it you will need boards or thick plywood, screws and a jigsaw. A workbench or a massive one is used as a bed chipboard(OSB).

The end of the pipe is fixed with a primitive stop. With the help of muscular force, the workpiece is given the required shape. The force should be applied smoothly, allowing the metal to “rest” after each approach. In this case, damage will be minimal, and the shape will be smooth and accurate.

To hold the part along the guide, a profile recess can be made at the end of the template. If you have a router, choose an end mill, or simply process it with a round rasp.
This method is only suitable for thin-walled pipes.

Stronger workpieces will simply destroy the wooden punch. If the metal is too thick and the pipe is short, you can increase the lever by inserting fittings into the free end. If the walls are thin, it would be wise to pour sand inside, plugging the holes with wooden choppers.

The lack of functionality of the device is compensated by its ease and low cost of manufacture.

Improved wooden model with pressure roller

A rolling pipe bender with a lever on which a roller is mounted works much more efficiently. Even if it is made of wood. With modern hand woodworking tools, you can easily turn wooden rollers of any size.

The diameters can be the same or different, it all depends on your tasks. The drawing clearly shows the principle of operation of the device, in in this case– the pressure roller and support roller are the same.

If you constantly work with small diameter tubes, you can make a more advanced tool with four bend radii. To do this, a square sheet of plywood is cut at the corners to the required size, and a hole is drilled opposite each for a lever with a pressure roller. Rearranging it to different angles– we get four bending options.

Perhaps the most common model among homemade products. Old pulleys from the engine are used as blanks, ordered at the factory from a familiar turner, and assembled from washers of various diameters.

Such a device is found in almost every barn or garage of a skilled home owner. With its help they bend plumbing pipes all common sizes. If necessary, the lever can be strengthened to any length.

To work with pipes or angles, a special machine called a pipe bender is required. This design allows you to bend metal elements to a given angle. If necessary, you can make a professional pipe bender with your own hands, which is used in the most various industries industry. Unlike the industrial version, a homemade pipe bender is much cheaper. When carrying out the work, you can use available materials, which will greatly reduce the cost of the structure. Let's take a closer look at how to make a pipe bender with your own hands at home.

Pipe bender device

There is just a huge amount various types the device in question. Before creating it yourself, you should develop a drawing of a pipe bender or download it on the Internet.

You can make a pipe bender for a round pipe with your own hands, taking into account the following features of its design:

Run-in. This type of pipe bending machine is characterized by the fact that one end of the workpiece is fixed, and a stationary template is used for bending. Running in is carried out using pressure rollers. This manual pipe bender design has been used for many years.
Winding. Special pipe bender for aluminum pipes characterized by the fact that the workpiece is pressed against a movable template, which is used as a roller. The broaching is carried out between the roller in motion and a special stop. As a rule, the drive is electric, since the required force is quite high.
Crossbow design. This scheme is represented by a combination of two fixed rollers, as well as a movable template. The force is transmitted to the workpiece through a movable template, which is located between two rollers. By controlling the movement of the moving element, the most suitable bending angle is selected. It is worth considering that the pipe bender punch, which acts as a template, can have a different shape.
Rolling or rolling. In this case, the scheme is represented by a device with three rollers, two of which are supporting and one is movable. The bending radius is adjusted by changing the position of the central roller. It is worth considering that such a device is considered universal, since the bending radius can be adjusted over a fairly large range. The dimensions of this type of pipe bender are relatively small, homemade design may be compact.

Choosing the most suitable design for homemade, it should be taken into account that the version operating on the knurling principle is often produced industrially due to the high complexity of the main mechanisms. The crossbow bending method is used extremely rarely today, as it has one significant drawback: the pressure is concentrated on the upper part of the template. When using a crossbow machine, there is a possibility of a significant reduction in the thickness of the pipe wall, as well as its rupture. It is not recommended to use such a device for bending thin-walled workpieces.

The most widespread design is one that operates on the rolling principle. It is practically devoid of all the above disadvantages, has relatively small sizes, can be portable, it is possible to adjust the bending angle.

A homemade machine can have the most different design. When choosing a type, attention is paid to what radius should be obtained. Most important parameters blanks that can influence the choice of a suitable design are the thickness of the pipe walls and its diametrical size.

Types of pipe benders

The design in question can be classified according to quite a large number signs. Available for sale universal options execution, as well as for highly targeted applications. The device differs in the following ways:

By drive type. An important design element is the drive, which can be hydraulic, electric, manual or electro-hydraulic. IN Lately The electric drive has become more widespread, as it is compact and very efficient. Hydraulic is more efficient, but it is difficult to operate, takes up a lot of free space and requires periodic maintenance. A manual pipe bender is distinguished by the presence of a mechanism that significantly increases the applied force. If we consider homemade options, then they make a manual pipe bender with their own hands. In addition, you can create an electric pipe bender with your own hands. But it’s almost impossible to make a hydraulic version yourself.
Classification is also carried out according to the degree of mobility. There are stationary and portable design options. In most cases, a universal manual pipe bender is performed as portable design. A homemade pipe bender for a round pipe can be attached to the base in various ways. It is worth considering that during the execution of work, part of the resulting stress is transferred precisely to the base. Therefore, when creating a homemade version, you need to ensure reliable fixation of the device.
According to the method of influence on the workpiece - the main sign of classification. For example, a crossbow-type pipe bender has its own special design, which is suitable for bending metal or metal-plastic pipes. In addition, there is a design that works on the principle of running, winding or rolling.

A homemade pipe bender for metal-plastic pipes can be the most various types, but most often they create a mechanical type, when due to a special design the transmitted force increases several times.

Instructions for making a pipe bender

Recently, the question of how to make a pipe bender with your own hands has become quite widespread. Such equipment is required when setting up production activities of various types. The simplest do-it-yourself pipe bender has a template type of design. This is due to the fact that it is quite difficult to make rollers for a pipe bender with your own hands.

Considering the template pipe benders for round pipes, we note the following points:

In the manufacture of structures, solid wood is often used. This greatly simplifies work and reduces costs. However, it is worth considering that the low strength and rigidity of wood determines the use of such a machine only for bending aluminum, which has high ductility.
Applicable wooden block must have dimensions that are larger than the diameter of the workpiece being processed.
The template must have a radius that matches the bending radius. In order to simplify the process, a small groove is created in the central part of the surface that is in contact with the workpiece.
For ease of operation, two handles are created, which have a metal fastening.
Having created a pipe bender at home, it should be attached to a solid base, and a stop should be installed on the reverse side.

An important point is that the design in question is applicable to a greater extent for large-diameter bending. In addition, a shoe for a pipe bender of this type is not required; the load is distributed evenly, which allows processing of thin-walled workpieces.

You can make a pipe bender with your own hands according to other drawings. Before choosing the most suitable design, you should consider how often the work will be carried out, for what type of workpiece the machine is made, and how mass production will be. The template type design is characterized by quite large sizes, however, to manufacture it, it is enough to carry out carpentry work; the materials used are low cost.

Most complex design is considered a homemade roller-type pipe bender. In this case, a pressure roller is used to transmit force. When making a structure, metal and wood can be used, it all depends on how mobile it should be and what force it is designed for.

The features of this design include the following points:

For pipes made from soft materials, wood is more suitable as the main material. It can be used to make a roller. For steel pipes, you will have to use metal, since the magnitude of the transmitted force will be significant. If desired, rollers can be purchased or made with your own hands at home.
Design features determine the presence of a movable and stationary roller. In this case, a U-shaped holder is located in the central part.
The bending radius largely depends on the size of the rollers used. That is why the movable roller must, if necessary, be quickly dismantled to install an option with a different diameter.
The holder you install must also be able to rotate.
A handle is attached to the installed holder; when rotated, force will be transmitted. It is worth considering that the handle acts as a lever. That is why the force that can be transmitted depends on its length.

Such a machine is suitable for production in large quantities, since it is quite difficult to make rollers for pipe benders with your own hands. The device is suitable for working with round pipes.

A common question is how difficult it is to manufacture such a mechanism. When using this type of bending machine, the following points should be taken into account:

First, you should study in detail the drawing or photographs of the equipment in question. Only by understanding the principle of its operation can you create effective equipment with wide scope applications.
This design has a relatively small number of main elements. An example is two pulleys, which can be made of wood or steel, a frame with a lever and a pressure roller. Quite important to create solid foundation, which will take part of the applied effort.

The principle of operation is quite simple:

The workpiece is placed in the groove of a stationary roller.
The pipe is fixed in the desired position using a clamp.
Using a lever, the workpiece is wrapped around a template, which also uses a roller of a certain diameter.

In order to significantly increase the efficiency of the design, an electric drive can be used. However, it is worth considering that when electric drive It is quite difficult to control the rounding diameter indicator. In addition, the installed electric motor must transmit rotation through a reduction drive, since the rotation speed of the roller is low. To do this, install a gearbox or V-belt drive.

Crossbow pipe benders

Enough unusual design has a crossbow type machine. It got its name due to its similarities with medieval weapons. The crossbow pipe bender has the following features:

The basis of the structure is represented by a frame, which can be made using angles and channels. The connection of all elements is carried out using welding; detachable methods are not recommended, since the resulting structure must have high rigidity.
After creating the frame, two rollers are attached.
A homemade version can be characterized by the fact that the force is transmitted directly through a mechanical jack. For a pipe of small diameter, the pressure created should be quite sufficient. The force is transmitted through a shoe made of durable metal with low rate plasticity.

A crossbow-type pipe bender is more suitable for round workpieces. This is due to the fact that a product with a different cross-section can be greatly deformed under pressure.

Hydraulic pipe bender

When making a pipe bending machine with your own hands, you should decide what type of drive it will be. In most cases, homemade versions are manually driven, since it is easy to manufacture and inexpensive. However, such a design cannot work with workpieces that are made using hard metals. A hydraulic pipe bender allows you to work with workpieces of large diameter and with significant wall thickness, however, the design is quite complex in design and has many features.

When making a machine for a round pipe with a hydraulic drive, the following points should be taken into account:

The force is transmitted through a working fluid, which is oil or water. All highways must have high degree tightness, and also be designed for a certain pressure.
A compressor can be used to create pressure.
Pressure is transmitted to the working element through a hydraulic cylinder.

A do-it-yourself pipe bender for metal-plastic pipes with a hydraulic drive can have a wide variety of designs. An important element in this case is the drive, which allows you to automate the bending process and increase the scope of application of the device.

Pipe bender from a jack

Most often, when making a homemade pipe bender, a jack is used as the main element. It comes in several types. The jack itself is initially made in order to increase and concentrate the applied force, due to which the structure can lift heavy mechanisms, for example, cars.

A homemade pipe bender made from a jack, as a rule, has a fairly simple design:

The workpiece is clamped between two stationary rollers.
The force is transmitted to the gap between the rollers.
The distance between the fixed rollers largely determines the bending radius and the amount of force required to obtain a certain angle.

As previously noted, when using a jack, you can make a crossbow-type pipe bender.

In conclusion, we note that almost any device is a relatively simple machine, which, due to the distribution of the applied force, bends pipes and other workpieces of a similar type. They are often used for bending products made using non-ferrous alloys and steel. The industrial version of the design outperforms the home-made one, as a rule, in terms of the degree of automation of the process. However, the cost of industrial pipe benders can exceed several tens of times the costs associated with the production of a home-made version. That is why a homemade pipe bender is more suitable for household use or small-scale production.
