A home-made bench-top pipe bending machine with three pinch rolls is one of the most popular fixtures in a home workshop or garage. This device is used to work with round and shaped pipes.
A home-made three-roll pipe bender allows you to bend the workpiece without creases and cracks. Moreover, the design of the machine allows you to easily bend round and shaped pipes of different sections and wall thicknesses. With this tool you can make arcs and rings. In this case, a radial bend with a smooth angle is obtained.
First of all, it is necessary to cut off two pieces of a corner of the same length. If there are no corners, but there is a channel at hand, then you can use it by cutting lengthwise into two parts. Then you need to drill through holes in the marked places and install the rollers.
The main stages of work
Then, using a grinder, cut out grooves in the corners. We make markings, after which we drill three through holes of different diameters. For this, it is convenient to use a stepped drill, which can be inexpensively bought on Aliexpress. Next, we carry out welding work.
At the next stage, we install the guides, as well as the screw for adjusting the position of the upper pinch roller. The guides are made of round timber and are welded to the shelf of the lower corner. Please note that plates are additionally welded on the inside of the corners so that threads can be cut.
The design of this device is quite simple, so everyone can make such a pipe bending machine. You can watch the step-by-step process of manufacturing a simple home-made three-roll pipe bender for a home workshop in the video on the website.
