Pipe bender for a profile pipe with your own hands

In the manufacture of structures in which a metal frame is used, it is often necessary to bend the metal pipe at a certain angle. Constructions from a square or rectangular pipe are used in the construction of greenhouses, the production of advertising signs, visors over the entrance doors, canopies, etc. In any of the listed products, it is necessary to use a metal pipe bent at a certain angle. To do this, you will need a pipe bender of the profile pipe.

Of course, with very frequent use of this mechanism it is better to purchase a factory copy. But with one-time use, you can make a pipe bender for a profile pipe with your own hands. Such a factory machine is quite expensive, and if you have the necessary skills and desire, you can do it yourself with your own hands.

The pipe bender for the profile pipe with its own hands is created from spare parts from transport equipment: automobile, motorcycle, bicycle and unnecessary materials. And if you think about the design, then the quality of the bent product will be the same as when working with the factory mechanism. The only thing in which, most likely, loses self-made benders is in aesthetics of appearance. But since the machine is intended only for work, and not for demonstration, a not very beautiful appearance should not become an obstacle.

To bend a pipe of small diameter (up to 2 cm), one can apply the simplest version of the construction of a pipe bend for a profile pipe, made with hand made from improvised materials.

To do this, you need a concrete slab. If it is not, then it is easy to make such a foundation: a concrete mortar is poured into the formwork, after hardening the plate is ready for further action. It drills openings for channels 7-10 cm or inch steel pins. For the main bending, the pins should be placed about 5 cm apart. You will also need to reinforce a pair of such at the edges of the structure at a distance from the main ones. The difference in size should be on the cross-section of the pipe, and we need to give a small margin for the composite penetration of the metal. Those. The last pair of stakes serve not for shaping the workpiece, but for fixing the pipe.

When a pipe bender for a profile pipe has already been made by hand, one end of the pipe must be fixed between the end stakes and the handpiece is slowly bent manually from the pins. Having reached the desired shape, the second end of the pipe is also fastened between the other last pins. Then, to stabilize the result, it is desirable for some time to weld the opposite side with a metal rod. This will not allow the product to take its original form. If you need to bend a very small number of pipes, then the stakes can be hammered and simply into the ground.

If a pipe of a certain diameter is to be bent in a large amount, then a more complicated version of the pipe bend for a profile pipe is suitable, it can also be adapted by hand. To do this, you will need a jack, a channel, a concrete base, 2 steel rollers, 1 steel "shoe".

The jack is securely attached to the channel and to the concrete base. The jack should be welded with the opening / closing handle, which will allow it to work. The lever for pumping the jack can be made from trimming an ordinary round pipe of a suitable radius. A roller shoe is connected to the jack. Two rollers are firmly screwed to the channel base.

The pipe is placed in the place of the bend on the shoe, under the rollers. When the lever of the jack is inflated, the shoe rises, bending the pipe. The workpiece is brought to the bend of the desired radius. Then the shoe drops and the bent pipe is removed.

In this unit, the pipe bends easily, smoothly and repeatedly! It is worth trying to collect pipe benders for the profile pipe with your own hands!
