Metal bending: what’s the pipe bending machine?

Metal bending has never been so perfect!

Have you always dreamed of doing metalworking in a more challenging way, however you never found the right solution because when you look for a way to make the job easier, you are no longer satisfied with the end result? There is a compromise that will guarantee you precise work in much less time! Metal bending has never been so fun, precise and fast!

What is the pipe bending machine

When we talk about tube bending, we are referring to the deformation of tubes or a profile with a rather small radius of curvature. Bending, in fact, is a cold pipe bending technique, which is done using special machines, called pipe bender machines.

With a pipe bender machine you can simplify your work. In fact, it allows you to complete the job in less time than when you do it by hand.

The first tube bender machines in the past were only able to bend round tubes; today, fortunately, this is no longer the case. Thanks to innovations in existing technologies, rectangular and square tubes and profiles can also be bent with the tube bender machine.

How the pipe bending machine works

First of all, the tube bender machine has two fixed wheels that are used to slide the bar or tube back and forth or even in one direction (depending on the model). On the other hand, the third one, by screw drive (manual action) or other type (automatic drive), slides through the two fixed wheels, so that the tube as it goes back and forth, begins to bend evenly along its entire length or in a certain section.

The pipe bender machine has the two fixed wheels and the die, that slides forward between the two wheels, imprints its shape.

It is critically important to understand how the bending process that is carried out with the tube bending machine works:

1. Firstly, the bending die shape is installed on the machine;

2. Therefore the bending die is stamped on the tube. Above all, during the bending process, attention must be paid to the possible deformations that inevitably occur in the outer and inner parts of the pipe bend due to mechanical bending. The inner part of the bend, called the intrados, is subject to tensile stress or elongation. This causes the thickness of the pipe to become thinner after bending.

There are several variables to consider for tube bending to be done correctly. For example, the elongation of the material, springback, aesthetics, and the ratio of the average radius of the bend to the thickness of the tube.

The tube bender machines operate mechanically. This enables our customers to speed up metal processing, shortening production and bending times and increasing work efficiency by reducing the margin of error even on large quantities of work.
