Pipe bender lever for a round pipe. Do-it-yourself pipe bender for a round pipe - video tutorials, drawings

Buying pipe benders for round pipes is not a problem with the current range. But if you need a tool exclusively 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 designed for pipes with a circular cross section with your own hands, you must 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 hydraulic. In this case, the machine can be homemade or factory. Making a good hydraulic unit with your own hands is not a problem. You will need a hydraulic jack for this. This option is good in that it makes it possible to bend round pipes that are decent in their parameters.
Mechanical. A less powerful homemade version of the pipe bender. With it, you can bend medium-sized products.
Manual. Manual drive is the most common in the household. Almost every homemade machine has a manual drive.
Electric. These are factory made units. You can make it yourself, but you will need the appropriate drawings, certain skills, an electric motor and a number of other components.

Whether you need to bend round pipes up to 30 mm in diameter or profile pipes up to 40 mm, a manual machine is the best solution. For more serious tasks, it makes sense to make a hydraulic pipe bender.

Homemade machine options

To get a pipe bender for a round pipe, it is not at all necessary to spend a lot of money on the purchase of 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 that allow you to get a full-fledged manual bender for round pipes in a short time.

Consider the following constructs assembled from:

nuts and metal tube;
Tree;
Kryuchkov;
Cylinder and rollers.

Let's start with the simplest and end with a machine whose technical capabilities resemble a hydraulic pipe bender.

Nuts and pipes

An elementary example of a 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.
A nut is fixed at the end of the rod. In this case, the nut should be chosen so that its inner diameter is 25-30 centimeters larger than the diameter of the bent round pipe.
Such a home-made machine can cope with a pipe with a diameter of up to 30 millimeters.
The connection of the rod with the nut can be done by welding. Another option is a threaded connection. It is more difficult to implement, but then you can change the size of the nuts. To do this, a small steel piece with a thread is welded to the nut. The handle also has appropriate cuts for carving.
The bendable pipe is placed on the floor. With your foot rest on one end of the pipe, and grab the other with a nut. Gradually move the handle towards you, due to which there is a 10 degree bend with your hands. Bend until you get the desired bend.

from wood

Another example of a simple do-it-yourself pipe bender for round products. It does not use many auxiliary parts, so the drawing is elementary.

Cut a semicircle of the required diameter from the board. You can make several of these elements if you want to bend pipes of different parameters;
The width of the section on which the pipe is laid must exceed the dimensions of the pipe itself. Otherwise, the product may break, 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 see photos, video instructions, it is not difficult to assemble a home-made pipe bender from wood.

From hooks

Good choice of machine. You do not need a drawing, but be sure to clearly follow the dimensions.

Apply on the table where the hooks will be fixed, markup for their fastening.
The hooks themselves are available at any hardware store. Choose those that are made of quality metal. Otherwise your pipe will just break them.
Attach the hooks to the base. The step 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 desirable to install an additional stop along the edges, which is stronger than the hook.
The advantage of the design is that you can easily bend the pipe with your own hands. At the same time, you do not have to make different templates for different pipes. It is enough to remove the hook and move it to another point in order to reduce or increase the angle.

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

From rollers and cylinder

This is not a hydraulic unit, but similar in technical capabilities to a hydraulic machine. With it, you can bend round pipes of a larger cross section. An indispensable device for repair, construction, when you do not want to spend money on buying factory installations.

The price of a finished manual pipe bender can be 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 up to 360 degrees, which is very serious.
Take a couple of metal plates. Their length and thickness are 30 cm and not 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 plank template.
To increase the strength, corners are fixed on 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, which will serve for installation. It is the bolt that will be the focus, so choose a durable element.
On the top plate, install the corners, rollers. The rollers should be oriented inside your machine.
The fixed cylinder and free-moving rollers allow for pipe bending work.

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

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

Your attention is invited to an article with step-by-step instructions and drawings for the manufacture of a rotary pipe bender for profile and round pipes. We will talk about the basic rules for assembling the lever and the bed of a home machine with our own hands and provide video instructions with comments.

At different stages of construction, installation of water pipes and other works, one often has to deal with the need for even pipe bending along a large or small radius. It is impossible to do this without a special device - the pipe is deformed and the quality of the product will come to naught.

A word about radii

A circular bend involves determining the size of the radius, which can be divided into three categories:

Small radius - from 50 to 250 mm. A bend under such a radius is appropriate to call a knee. It is performed on round water pipes Ø 15-75 mm, or on square pipes 15-25 mm (decorative forging).
The average radius is from 250 to 500 mm. It is often used for the manufacture of ring molds from a 40x3 strip, a pipe Ø 15-75 mm, a square (15-25 mm) or rectangular (up to 20x40 mm) profile - the rim of barrels, tanks.
Large radius - more than 500 mm. It is used for the manufacture of arched elements - greenhouse frames, canopies, ribs of welded structures. Usually it is a square (15x15, 20x20) or rectangular profile 20x40, 40x60 mm. Arches are usually not made from a round pipe - it is inconvenient to attach a distribution crate to them, but a round pipe of large radius can be bent with a diameter of no more than 75 mm.

The radius on thicker pipes is performed not by bending, but by segmentation - when the elbow is cut into segments and welded.

Small radius bends are in most cases required on water pipes Ø 15-38 mm. Often the very fact of bending at the right angle is more important than its quality. In the everyday life of masters, there are two types of pipe benders for this task - three-point and rotary.

How to make a rotary pipe bender with your own hands

This type of tool can often be found in the "manual" version. The force is applied by the operator through the lever. The fixture is easy to make, having the skill of a locksmith and a welder. To do this, you will need the main elements - a lever, two wheels from blocks (with grooves) of different diameters, a steel plate and other metal parts.

First you need to make a powerful fork (metal at least 5 mm) for the thickness of the wheels. This requires a calculation. Suppose we need to bend a pipe with an outer diameter of 25 mm. We have wheels (bearings) of two diameters at our disposal: r 1 = 250 and r 2 = 100 mm (radii 125 and 50 mm, respectively). The radius of the larger wheel will be the inside radius of the knee.

The fork will look like this:

The design of the pipe bender

The main size of the lever fork is the distance between the wheels ( d=25) - the seat of the pipe and should be equal to its diameter plus 1-2 mm. In our case, it is 25 mm.

Note. If the wheels have a chute, the inside point of the chute is taken into account.

The next step is to determine the distance between the axles of the wheels ( a) according to the formula:

a \u003d d + r 1 + r 2 \u003d 25 + 125 + 50 \u003d 200 mm

Next, you should determine the sufficient size of the fork, based on the distance between the axles of the wheels ( With). Here you need to adhere only to the approximate gap between the small wheel and the rear wall of the fork (take 10 mm), as well as the stock of metal for fastening the stationary axis of the large wheel (take 30 mm):

c \u003d a + r 1 + 10 + 30 \u003d 280 mm

The gap between the fork legs ( v) will be equal to the thickness of the wheel plus 1-2 mm (take h = 30 mm).

The small wheel will be mounted on an axle fixed to the fork legs. Try to use a bearing on this axis - this will greatly facilitate the work compared to a simple (“dry”) mount.

If the task is to make a pipe bender for several pipe diameters (from 15 to 38 mm), the distance between the fork shelves should be sufficient to install the thickest pipe possible. Make the fork leg longer and drill holes for the stationary axle for each of the diameters.

Node 1 - fastening the lever to the fork - if possible, make a reliable threaded connection with welding. Simply welding the lever handle “at the end” will be unreliable, because it is through this point that the entire load is transmitted.

A steel plate 350x200 mm or more with a thickness of 8 mm or more is suitable as a basis for a pipe bender platform. Consider immediately what the purpose of the machine will be - stationary or portable. Provide mounting holes in the plate Ø 12-20 mm.

Platform design: 1 - emphasis; 2 - mounting holes; 3 - lever; 4 - direction of force at the moment of bending; 5 - axle fixed on the fork; 6 - pipe; 7 - stationary axis

The stationary axle can be made from a regular pin, welded in the center of the plate, but it is better to use a bearing or a bearing bush. The stop is fixed in place after assembling the rotary mechanism. If the machine is designed for one diameter, the stop (corner 50x50 mm) can simply be welded to the platform. If there are several diameters, empirically establish the location of the stop for each of them, make holes in the appropriate places and pick up the rods (fastening "on the finger").

How a pipe bender works, video

The precisely executed machine is complemented by clamps for bending thin-walled pipes. This approach is relevant in production, where work is carried out mainly with one or two types of pipes.

Video: pipe bender in production

This basic model can be improved by making the wheels movable along the mounting axis, thereby expanding the range of radii. This will require more ingenious solutions and precise execution of details.

DIY advanced manual pipe bender, video

Factory machines and tools for setting small radii have the same unchanged principle, but are arranged differently. More convenient and perfect fasteners that are easily and quickly rearranged, mechanized labor, precise execution and respect for the workpiece are what a professional who is used to working a lot and with high quality needs.

Manual electric pipe bender

It is possible to produce the main parts of complete machines with high quality - the system of stops and levers - only in the factory.

Observing the basic rules and the very principle of pipe bending, you can use any available parts to improve the machine.

When assembling a heating or water supply system from metal pipes, it often becomes necessary to bend them in order to give one shape or another. For these purposes, there is a special tool - a pipe bender, which you can either buy, although it costs quite a lot, or make it yourself. In this material, we will talk about how to make a pipe bender for a round pipe yourself, as well as what types of these products are found.

Scope of the tool

It is worth noting that pipe benders for round pipes have a fairly wide scope, and this is far from just plumbing work. By the way, when installing plumbing, the need to modify the contour of the pipe does not always arise. As a rule, swivel fittings and bends are used to create bends in pipelines. Elbows mean sections of pipes bent according to standard templates at the factory.

There are some restrictions for withdrawals:

standard set of rotation angle options - 45º, 60º, 90º, 180º;
bending radii can be equal to 1 or 1.5 Du;
connection - only welded.

In some cases, it is impossible to fit an individual heating or water supply system into such a rigid framework, and it is not always acceptable to use the welding method of fastening. Then you will definitely need a homemade pipe bender for a round pipe.

In household and summer cottages, there can be many situations when it becomes necessary to bend pipes. This includes the creation of greenhouses and hotbeds with unusual shapes, and the installation of frames for grapes or weaving flowers, and the construction of a summer shower or a small fence, in a word, there are many options. At the heart of all these structures is a frame made of round pipes or a profile, which must be given one form or another. This is where manual pipe benders for a round pipe come in handy.

Note that professional craftsmen do not hesitate to use such a hand tool, because it perfectly meets all the requirements and parameters of the owner. A hand-crafted tool allows you to do quality work, because it is very convenient to use.

Device types

In order to classify products into different categories, several signs are used:

Drive type - manual, automatic, hydraulic.
The installation method is portable or stationary.
Operating principle.

According to the principle of operation, all pipe benders can be divided into several types:

Winding. The stop is located at the beginning of the bend. With special clamps, the pipe is pressed against the movable template roller. This roller begins to rotate, passing the pipe between itself and the stop. This is how the bend is made.
Running in. With this method, the pipe is fixed near a fixed template. The pressure roller begins to rotate around it and gradually bends the pipe to fit the template.
Rod or crossbow method. A pipe is fixed between two fixed rollers. The pressure on it is made in the center using a template located on the stem. It gradually lowers, bending the pipe in the center between the support posts.
Rolling (rolling). In this case, pipe rolling assumes that two rotating support rollers placed in one line and one central template are used for bending. The ratio of these elements will depend on the bending radius. As a rule, the pressure on the pipe is exerted by the central roller.

It is worth noting that in the first three methods of work there is one common drawback - in them the radius of the pipe bend directly depends on the template.

Pipe bending by winding, as a rule, is performed only on industrial equipment, since a do-it-yourself pipe bender for a round pipe is not suitable for these purposes. For products subject to the crossbow processing method, a weak point appears - where the upper part of the template acts on the steel. This area is subjected to strong pressure and becomes brittle, weakens and thins. In some cases, the pipe may even burst - if its walls are thin enough.

But the rolling method is used to form the pipe configuration most often. Moreover, it is used in industrial enterprises for the production of bends.

In order to properly manufacture a tool, you need to choose its model, taking into account the relationship between the bending radius and the cross section of the pipes. These data can be found in the special recommendations in the form of a table. And, although the figures given there are optimal, the bend radius can still be reduced.

However, for this purpose, you will need a mandrel, which will significantly complicate the work. If we talk about factory conditions, then in addition to the mandrel, hot rolling is often used in production.

However, hot rolling can also be done at home if you have a stationary metal pipe bender with a fixed bed at your disposal. Then a blowtorch or a gas burner is used to heat the pipes.

DIY pipe bending tools

Since it is possible to make a home-made device for bending pipes both from improvised and used components, the cost of such a tool will be quite low (more: ""). Moreover, for the manufacture of the simplest pipe benders for a round pipe with your own hands, drawings are not required. For example, consider a fairly simple design of this device.

To bend the pipe, one of its ends is fixed between the metal elements and pressure is applied to the opposite end until it acquires the desired shape. After that, the pipe is left in this position for some more time so that it does not unbend. For this, metal pins are also threaded at the ends of the pipe, which are welded to a temporary jumper.

Actually, this is the simplest type of pipe bender, which is not a problem to make. But there are also more technological products. We will write about them below.

Hand Template Bender

This tool is used for bending. It is made of wood, equipped with a manual drive.

First, according to the drawing, a wooden template is made, the shape of which will coincide with the bending radius, and the thickness must be greater than the diameter of the pipe. The profiling cut out on the end of the template will simplify further work with the tool. To get the desired profile, you can take two boards, the cut line on which is beveled inward.

The base to which the template will be attached must be fixed. On one side, an emphasis is screwed to the platform, after which the pipe is tried on. If the length of the lever is insufficient, a piece of reinforcement can be inserted into the pipe. There is no need to rush during bending - it is important that the pipe does not move during operation and clearly corresponds to the shape of the template.

Of course, such a primitive mechanism is not something intricate and technically complex. However, for work at home, it is quite acceptable, especially if you need to bend thick pipes.

Roll-in pipe bender made of steel

The most popular among homemade tools is a break-in pipe bender. The templates in it are made from pulleys from engines. Although, some prefer to use washers with different diameters or turn the part on a lathe. It is not necessary to draw a drawing in this case, but it is desirable, for example, so that the turner can correctly machine parts for pipe benders for a round pipe.

Such a hand tool of the break-in type is made by many diligent owners who are constantly making and improving something in their home. The advantage of such a pipe bender is that it can work with plumbing pipes of any standard diameter. And to make the applied force more, you can make the lever longer.

Homemade winding machine for bending pipes

According to the principle of operation, such a tool is similar to a break-in tool. However, it can be used to give the pipes the shape of a ring, which is impossible to do on any other device. If we consider in detail the drawing of the fixture, we can see that the cheeks of the template pulley can be dismantled in order to remove the workpiece in the shape of a circle from it.

It is worth noting that a pipe bender of this design can be made from any available materials, including wood, metal or textolite.

How to make a pipe bender for round pipes with hydraulic drive

If we are talking about not just doing some home repairs, but about professional activities, then you should think about making a more complex hydraulic pipe bender. With its help, when bending pipes, it will be possible to reduce the cost of physical forces, because the load will fall on the hydraulic jack.

At the stage of drawing up the drawing of the device, it is necessary to foresee what material the sidewalls will be made of. Optimally suitable for this is a reinforcement bar with a cross section of 18-20 mm, as well as corners with a side of 25 mm. In addition, for the sidewalls you will need 10 mm thick sheet iron with drilled holes for fixing the supports.

A tube of the appropriate diameter is used as a support, into which a bolt with a cross section of 18 mm will need to be welded. A semicircular hole will be located in the center of the support, which also needs to be reflected in the drawing. The workpiece will have to rest against this recess, which will be bent on a hydraulic manual pipe bender.

To create a punch, you will need sheet metal 4 mm thick, from which you will need to cut semicircular blanks. The radius of these parts must correspond to the planned bend radius of the pipe. At the next stage, a pipe with a cross section of 32 mm is taken and cut into two parts. One of the parts is bent according to the shape of the blank plates, and then all the parts are welded. For additional strength of the punch in a hydraulic pipe bender, jumpers are welded inside it, providing stiffeners.

A tube is welded in the central part of the platform. Its purpose is an emphasis for a hydraulic drive, which is a jack. All this must be worked out and provided for in the drawing, according to which the hydraulic pipe bender will be assembled. In addition, such a scheme will make it possible to prepare a list of materials and components that have the necessary parameters. In this case, a number of elements for the tool will need to be pre-ordered from the turner.

Thus, it is not so difficult to assemble one or another type of manual pipe bender. Moreover, there are a lot of options and drawings of finished products that you can take into service in order to make your own necessary tool in the household.

The pipe bender for a round pipe is actively used in the laying of water, heating and sewer networks. Also, craftsmen use them to create decorative elements. For work, it is not necessary to preheat the material, including steel blanks.

According to the type of drive, the pipe bender can be:

Manual is a rolling mechanical bender for household tasks and occasional use. One of the advantages is an attractive price.
Hydraulic - hydraulic drive allows you to increase the pressure without applying additional physical effort. Suitable for thick-walled profile pipes.
Electromechanical - an industrial version for serial production. The electric drive allows you to significantly speed up work processes.

How much a bending machine costs depends on its characteristics and functionality. To choose the right model, call our manager - they will help you make a choice and answer all your questions! Possible sale in installments.

When carrying out repair work, it often becomes necessary to give pipes a certain shape. Although here you can resort to improvised tools, you can still achieve the best effect if you use a manual pipe bender. This tool can be purchased at any specialized store, but if you wish, you can make it yourself. Every craftsman should take care of the presence of this device in his arsenal, since at the most unexpected moment it may be necessary to bend tubular products.

According to its design, this tool is distinguished by a number of features, thanks to which it manages to bend metal pipes without any problems, giving them the required corner radius, which is carried out with minimal physical effort. The equipment available today for bending profile and round pipes can be divided into several types:

hydraulic;
manual;
spring;
mandrel.

Along with them, one can distinguish tools and other execution:

crossbow;
segment;
electromechanical.

All of the above tools have certain positive and negative qualities, but any of them allows you to bend a round metal pipe in a short time and with minimal physical effort.

The easiest option is to visit the nearest specialized store that offers such tools. But if the owner has experience in making a wide variety of devices with his own hands, then he may consider creating a manual pipe bender at home. But before you start assembling such a device, you should prepare everything you need: drawings, materials and certain tools.

The main purpose of the device

In recent years, a variety of profiled metal blanks have become widespread, on the basis of which fences, nets, garden furniture of unusual design are created.

Profile pipes have gained wide popularity as a material for the manufacture of structures for car sheds, garages and greenhouses, and in addition, arbors in the country. The design of such products provides for a wide variety of elements, and they certainly include curved pipes.

To perform bending of a profile or round pipe in order to give it a certain shape, in most cases they resort to such a device as a pipe bender.

Having such a versatile tool at hand, the owner can effortlessly bend a profile and round pipe at a right angle, for which he does not need to exert significant physical effort.

Such devices may be equipped with a hydraulic or electromechanical drive. In this case, the most common option are pipe benders with a manual principle of operation. Such a device allows you to perform certain operations with pipes small and large diameters for various purposes.

Today, equipment such as a pipe bender for profile, metal, and metal-plastic pipes is widely used in various industries.

If we talk about their use in industry, then usually here we mean professional pipe benders, which are driven by a hydraulic or electromechanical drive.

If the task arises of using the device to solve everyday problems, then most often the choice stops at home-made units, for the manufacture of which improvised materials are used. Naturally, you can avoid all the problems that accompany the process of making a pipe bender with your own hands if you visit a specialized store and pick up a version of this tool there that meets the requirements. However, making a pipe bender with your own hands is attractive primarily because it saves a considerable amount of money.

Design features

Regardless of whether you plan to purchase a pipe bender in a store or make it yourself, it may have different designs, which is determined by its type and purpose.

Each such device is characterized by certain elements that are presented in the design of any pipe bender model:

rigid frame;
hydraulic cylinder;
metal strips;
strong supports
rollers for pipe bender.

If you plan to assemble a pipe bender with your own hands, then it must necessarily provide for the above elements. Pipe bender frame can be made in a closed or open version. The hydraulic cylinder will act as the element on which the main power load will fall. A home-made apparatus for bending pipes must certainly be equipped with a pressure device, for the placement of which a place is chosen for the extreme part of the body.

In addition to this, it is important to take care of the presence of a bypass valve and a handle that will provide convenience when bending pipes.

To simplify the process of servicing the hydraulic cylinder, it is useful to provide in the design such an element as a plug that will allow you to fill in oil. Rollers will simplify the bending process.

To avoid errors when bending pipes, care must be taken that the profile or round pipe is rigidly fixed.

The key role in pipe bending will be assigned not to rollers, but to rising stem, and it must be able to return to its original position. This problem can be solved by equipping the tool with a strong spring.

The upper and lower metal strips must be securely fastened, for which it is recommended to use welding. An important role in this device is given to the stop, for which it is mandatory to have a strong and reliable design that can withstand significant loads.

Most often, the device of a pipe bender with and without rollers provides for certain design features that must be given in the drawing to it without fail. Create reliable pipe bender it is possible with your own hands, provided that, in addition to a correctly drawn up drawing, you have the necessary structural elements for this.

The most common version of such devices is a manual type pipe bender with rollers, with which you can quite effectively bend pipes into arcs and rings. Among the distinguishing features of such a device, it should be noted small size and weight so that it can be easily moved to another location. This tool will bring considerable benefit if it is necessary to deform light metal structures, for example, greenhouse frames, gates and awnings.

In some cases, this equipment can be used in combination with a variety of mandrels. This expands its functionality, allowing you to bend profile pipes. Pipe benders of this design are offered in most professional stores, although each owner is able to make such a unit and rollers for him on his own.

Features of pipe benders

In industrial enterprises, pipe benders with electric drives are most widely used. In addition to the wide range of tasks that they can successfully solve, this tool with rollers demonstrates high performance.

With the help of a pipe bender, you can perform operations of a different nature, but, given its specific application, it is not so easy to assemble it with your own hands. In a situation where enterprises need to deform large-diameter metal pipes, they usually resort to the help of pipe benders with rollers equipped with a hydraulic drive. With the help of such a tool, you can create significant efforts to solve the problem, and this device itself can easily cope with high loads.

Pipe benders with rollers equipped with hydraulic drive, most effectively cope with their task in the construction of gas and water pipelines, where a significant amount of work is planned. The presence of a special hydraulic installation in the equipment of such a machine relieves the operator of the need to exert any physical effort to deform the products.

When making a do-it-yourself pipe bender with rollers, you should remember that this operation is quite complicated. In case of violation of the execution technology, one may encounter the appearance of defects on the material, including cracks that may occur in the bending areas. Working as a pipe bender, the owner has the opportunity to perform any operations on workpieces, providing the desired shape with minimal physical effort.

All available types of pipe benders with rollers are united by the fact that the same principle is put at the heart of the work.

Operation features

The first step in the manufacture of a pipe bender is the preparation of a working template that will contain all the necessary configuration information for the workpiece.

After that, using the stop, the bending pipe must be fixed, and then they begin to bend by making smooth movements along the contour of the template.

In some cases, the workpiece may yield to the template in size. In this case, you will need to build it up using a small piece of pipe for this purpose.

A mandrel-type pipe bender does its job in the same way as professional devices. If there is an interest in pipe benders for domestic use, then it is best to work with a roller-type device, which can be made on your own or purchased from a specialized store.

Assembly order

Even before you start manufacturing a device for bending pipes, you should prepare all the necessary material and tools.

You should also take care of the availability of a drawing, where the details should be given device components and their description.

Work technology

The first step in assembling the pipe bender is to make the base of the machine. It is very important that the walls of the pipe used have a rectangular cross section and the required thickness.

A hole is drilled in the pipe, where the main pulley will subsequently be installed. The unnecessary part must be cut off with a grinder.

After that, they begin to assemble the lever: by welding, it is necessary to fix a nut on one end of the stud, and a lock on the other.

Next, it's time to make a handle, for which you will have to use steel plates and rubber fragments. After the handle is ready, it must be fixed as rigidly as possible on the pulley.

The next step is the general assembly of the entire pipe bender structure. It is necessary to take the plate from the handle of the machine and fix it on the base of the device. Then they begin to install the main pulley.

Having finished assembling the pipe bender, you should check it in operation. It is necessary to take a pipe blank and try give it any shape.

If after completion of the tests the result is satisfactory, the machine is ready for operation.

Conclusion

Every home craftsman who often has to deal with pipes, creating various structures and systems based on them, should think about the presence of a pipe bender. Here it is not necessary to go to the store and purchase pipe bending equipment there. Having the necessary materials and tools available, as well as knowing technology for such work, you can quite easily make a pipe bender with your own hands. Such a solution is preferable in view of the fact that it allows considerable savings in the cost of manufacturing such a device. And as a result, the owner gets quite reliable equipment that will help him simplify the process of deformation of various tubular products.
