How to make a pipe bender for right angle bending without jams

It is very difficult to bend a pipe at a right angle without crushing its inner diameter without a special machine. Muzzle constriction from bending is undesirable, especially when it comes to the installation of heating systems, water supply. If you are installing piping, then make this simple yet effective pipe bender.

Materials:

  • Pipes of different diameters;
  • channel;
  • bicycle sprocket;
  • bolts М10 – 2 pcs.

Pipe bender manufacturing process

It is necessary to select a pipe into which the bending tube can be inserted with a minimum clearance. This workpiece needs to be bent at a right angle.

Without a machine, this will work if you make cuts with a grinder along the bend, and then weld these seams.

The resulting part is shortened and cut lengthwise.

One half must be boiled along the cuts inside, and then cleaned the seams. This is necessary so that the workpiece does not unbend under load. A tube is welded to the reinforced part in the center. Thus, we get a pusher.

To the second half you need to weld 2 tubes along the edges. To do this, they are cut obliquely from one end, and welded onto a piece of strip. Then, a half of the knee is welded to the resulting mount. As a result, we get a backwater.

The combination of a pusher and a stop, placed under the press, allows the pipes to bend, but slightly crushing them. If this quality is unacceptable, then you can slightly change the design, and instead of a hard stop, make a swivel mechanism.

To make the mechanism, you need to cut a pipe with a length of 30 mm. Thin transverse tubes are welded to the halves from below.

Next, cut off a piece of the channel. We insert bolts with bushings into thin tubes, and bait the nuts. Then you need to weld bushings and nuts to the channel. In this case, the halves on the tubes will be able to rotate. To increase the rigidity, you need to weld a bridge between the nuts, for example, a piece of a bicycle sprocket.

Such a pivot support, when compressed by the pipe pusher, changes the angle, so the knee is generally perfect without dents, as in the previous version. Both designs allow you to make bends of sufficient quality for piping systems, but in the second case, it is higher.
