It is very difficult to bend a pipe at a right angle without crushing its internal diameter without a special machine. Choke constriction from bending is undesirable, especially when it comes to installing heating systems and plumbing. If you are laying a pipeline, then make this simple yet effective pipe bender.
Materials:
- Pipes of different diameters;
- channel;
- bicycle sprocket;
- M10 bolts – 2 pcs.
Pipe bender manufacturing process
It is necessary to select a pipe into which the bending tube can be inserted with a minimum gap. This workpiece needs to be bent at a right angle.
Without a machine, this can be done if you make cuts along the bend with a grinder, and then weld these seams.
The resulting part is shortened and cut lengthwise.
One half needs to be boiled along the cuts and inside, and then clean the seams. This is necessary so that the workpiece does not bend under load. A tube is welded to the center of the reinforced part. Thus, we get a pusher.
To the second half you need to weld 2 tubes at the edges. To do this, they are cut diagonally at one end and welded onto a piece of strip.Then half of the elbow is welded to the resulting fastening. As a result, we get support.
The combination of a pusher and a stop placed under the press allows you to bend the pipes, but slightly crush them. If such quality is unacceptable, then you can slightly change the design and make a rotating mechanism instead of a rigid stop.
To make the mechanism, you need to cut a 30 mm long pipe lengthwise. 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 tighten the nuts. Then you need to weld the bushings and nuts onto the channel. The halves on the tubes will be able to rotate. To increase rigidity, you need to weld a jumper between the nuts, for example, a piece of a bicycle sprocket.
Such a rotary support, when compressed by a pipe pusher, changes the angle, so the elbow is generally perfect without dents, as in the previous version. Both designs allow making bends of sufficient quality for pipeline systems, but in the second case it is higher.
