The basic machine for manual production of heat exchangers comprises a tube-feeding device and a rollbending device.
The tube is inserted into the machine from behind and transported to the bending unit with the 14 rolls. There, the tube is shaped as programmed by 5 bending rolls.
For more complex geometries, the bending unit is expanded by two additional axes. The pitch and diameter rolls can be adjusted automatically during the process; his online measuring and adjustment is unique on the market!
The roll bending machine can, of course, also be used partially/fully automated in different versions. The bending machine can be additionally supplied with a magazine to feed in tubes at a fixed length.
To reduce cut-offs, a welding station can be integrated between the magazine and the roll bending machine to connect the tube ends and produce an “endless tube”.
An additional cutting station can be installed at the roll bending machine front to separate the heat exchanger from the “endlesstube”. This is where the transverse welding seams are automatically removed if they are located in the spiral bends.
