Optical measuring system integrates into tube bending tool

Schwarze-Robitec has developed the Springmatic optical measuring system. Integrated into a bending tool, it measures bent tubes directly while tensioned on the bending machine and either starts the required bending process or saves the correction value for subsequent bends.

Tube processors can bend, measure, and adjust in a single stage. Immediately after the bending of a tube, the system records the rebound value, from which the bending machine's CNC calculates the required subsequent bending angle. Subsequent bending is carried out either automatically or after clearance by the machine operator. The dimensional stability check and tube postprocessing takes a few seconds per workpiece.

The unit checks both thick- and thin-walled tubes in a variety of materials and diameters. It can be integrated into almost any bending tool and combined with almost all tube bending machines from the manufacturer.
