What is a tube bending machine used for?

Tubes are straight workpieces, as long as they have not been produced through milling or moulding. The conditions through which tubes are assembled does not allow for standard features such as bends, curves and angles. After the production of tubes, they have to be individually processed in order to fit them with the required features. This is the stage, where a tube bending machine is used. Tube bending machines can also be used for the mass production of bent tubes, such as automobile exhaust pipes.
  • Tubes are straight workpieces
  • These pipes are continuously produced and then need to be individually bent into form
  • There is a large range of industrial tube bending machines available for this process

How to do tube bending machines work?

Tubes cannot just be bent using force, as they would snap or the form would end up having an imprecise shape. Assistants need to be available, due to the amount of work required to bend a tube. A tube bending machine has a clamping system where the workpiece is held in place. Then the tube is pulled into shape, over a bending tool, using a lever system. To bend the tube into the desired shape, one can insert the appropriate bending tool. This construction is best used for thin-walled tubes. The power that is asserted onto the tube during this process is distributed evenly over the bending tool.

This ensures that the tube does not snap. Tube bending machines with bending tools are particularly suited for mass production because they work very quickly, precisely and lastingly. One of the problems during the use of a tube bending machine with bending tools can be the extensive retrofitting required for these machines, and the restricted resilience of the bending tool. Additionally, this process is not efficient for bending individual tubes. For this, the three-roll push bending process should be used. Machines used for this process have three rollers on one level that are in the shape of a V. They shift and swap places, so that a variety of tube shapes can be processed. After the workpiece is clamped in and the machine is programmed, the tube is bent into the desired shape as bending machine moves the middle roller between the other two rollers.

What types of tube bending machines are available?

There are as many types of tube bending machines available, as there are varieties of tubes. Bending machines are available for tubes measuring under 2mm in diameter (for example, those used in pens) up tubes made for pipelines. Pneumatic, manually, mechanically and hydraulically operated machines are available on the market.
