Flexible Tooling

STENHØJ Universal 'Floating Tool' Concept
The STENHØJ bending tool will bend any chassis beam used in the heavy truck industry. The bending tool is flexible and will automatically adapt to any beam dimension without tool change or manual interference. A diversified concept of various design in the tooling can be changed individually in the quick tool change device.

Advanced software

'Learning by Doing' System
The Truck Chassis Offsetting Line is equipped with an intelligent 'Learning by Doing' control and correction system that controls and auto-corrects bending angles in both directions (+/-) if required.

Intelligent Machine Learning
The intelligent “Learning-by-doing” system works fully automatically for initial as well as for subsequent bends. Each bend, for each beam type, is being processed entirely individually by the system, and machine learning data is stored individually.

Full Automatic Control and Correction
For each bend, the system will measure the starting position and the achieved bending angle. If the angle lies within the desired tolerance, the machine will proceed to next step.

If the angle is not within tolerance, the computer will automatically calculate an appropriate correction to reach desired tolerance by using the factory pre-installed correction program. The calculation program will take all variables of the beam into consideration, such as spring-back, thickness etc.

The correction program will be running constantly throughout the entire bending process to ensure optimal accuracy and repeatability.
