Good day friends. Today there will be an interesting article for people who like to craft with their own hands. With the help of a pipe bender or as it is also called "Profile bend", you can bend metal pipes to the shape you need.

In this article I will tell you how to assemble it yourself, but if you do not like reading, you can watch the video at the end of this article.

How to make a pipe bender with your own hands (Frame)

The first step is to weld the frame. In our case, this is a T-shaped support. You can make it from a channel and four metal corners, which must be welded to the channel in a vertical position as in the photo below.

There must be space between the corners for the pressure roller to move.

The top cover can be made from a channel or from two metal corners, as is done in our case. The upper cover will be attached to the upper part of the pipe bender, a high nut will be welded onto it, on which a hairpin will walk, thereby pressing the carriage to the pipe.

I'll tell you more in more detail below.

It will be attached to the bolts, so that the pipe bender can be disassembled.

How to make a pipe bender with your own hands (Carriage)

The carriage can also be made from a piece of channel. The pressure shaft will be attached to it and the stud will be welded.

In the carriage, you will need to make a hole for the stud and cut the grooves for the pressure shaft.

The metal plates will serve as a spacer between the pressure shaft and the carriage cover.

The size of the plates will depend on the width of the carriage cover.

How to make a pipe bender with your own hands (Hairpin)

The hairpin can be any. The thicker the better, the main thing is not less than 16 mm. in diameter.

A high union nut is also needed. A hairpin will walk on it.

How to make a pipe bender with your own hands (Rollers)

There are three of them you need to make. One will act as a pinch roller and will be attached to the carriage cover, while the other two will be removable. We will install them on supports, the pipe will be rolled over them.

It only remains to mention the supports.

We made the supports from a 25 x 45 mm square pipe. Support height 100mm.

We cut out a seat on the supports, but then we realized that we had done it in vain. In the video, I explained why.

Well, that's basically all we need.

All that remains is to buy bolts and washers. Let's move on to the assembly.

How to assemble a pipe bender

Assembling the carriage is the hardest part of making a pipe bender!

In the center of the carriage cover, you need to drill a hole in the diameter of the stud.

Grind the thread 4-5 centimeters onto the studs on one side.

The hairpin should move freely in the hole.

Now you need to weld the nut to the stud.

That's the way it is.

Attention: Weld the nut only to the stud, not to the carriage cover. The pin must be able to turn quietly in the hole!

On the reverse side, you also need to weld on a nut, so that the pin can rotate around its axis in the carriage.

The pressure roller is welded to the carriage through the spacer plates as shown in the photo.

Important: bearings cannot be welded to metal, therefore, metal covers must be made on the bearings, which will be welded to the cover, and the bearings will be inserted into them.

When the carriage is assembled, it should be lowered into the cylinder of the pipe bender.

Important: the carriage should be made 1-1.5 mm. less cylinder. It should move freely in the cylinder.

We pass to the top cover.

In the top cover, you also need to make a hole in the center and weld a high connecting washer there.

It is also necessary to make four holes for the fastening bolts.

It remains to weld the supports and install the rollers.

We weld a nut onto the bushing of the pressure roller so that it can be rotated with a ratchet or screwdriver.
