RB60

The precise 3-roll bending machine

During the development of the compact and mobile horizontal bending machine, the focus was clearly set on the production of dimensionally accurate spirals such as handrails for spiral staircases. This is the supreme discipline, since two mutually influencing variables (radius and pitch) must be combined in a bend to form a dimensionally accurate geometry. The interaction of tube calculation on the PC, implementation on the bending machine, and control via the measuring equipment with final correction of the bending values ensure accurate bending. By simple and few inputs into the PC tube calculation program, the local printer provides a printout and supports the calculation of all necessary bending and correction data to operate the machine. A new powerful drive concept allows infinitely variable adjustment of the bending speed, requiring only a 230 V (AC) connection. Hardened steel tools as well as hard plastic tools that are gentle on the surface are available for selection. To ensure optimum feed even with tight bending radii, all three bending shafts are driven. The drive concept also proves its worth in tough daily use on the flat, when bending tubes and profiles. Customers of the 4800, 5000 and 6000 bending system have the option of purchasing the roller bending unit without the drive. The roll bending unit, designated RB43, can be adapted to the 4800, 5000 and 6000 bending systems via the bending shaft. The machines function here as a drive unit.
