Speed Control Gas Springs in Press Tools

Speed, safety, and reliability of production equipment are often decisive factors for vehicle manufacturers. Being able to produce vehicle parts in a timely manner without compromising safety, while at the same time ensuring production equipment is not subjected to unnecessary wear and tear, becomes essential for efficiency. A production stop because of damaged manufacturing equipment can be a costly matter.

The sustainability of a press tool is also a significant cost factor. Frequent intervals of maintenance, spare parts, and service, or replacement of an entire die, add to production costs and slow down production speed and efficiency.

Faster, Safer Vehicle Body Production

When cutting sheet metal with pressing tools in a die, it is particularly important to ensure that the pressing tools remain within safety norms — for e.g. bounce — yet still perform a number of actions per minute to keep productivity at the desired level.

The bounce of a press tool commonly occurs because of increased return stroke speeds from a new generation of presses. The bounce of the blank holder because of stroke speed can cause unnecessary damage to the press.

This can be solved by adding or implementing KALLER® SPC Gas Springs in a die. With speed control, the return stroke speed at which the blank holder is being lifted slows down towards the end of the piston rod travel. This provides for optimal balance between speed for productivity by achieving more strokes per minute while halting unnecessary tool bounce.

The KALLER SPC Gas Springs are a productivity-enhancing and damage-reducing component for many vehicle manufacturers and are often included in different vehicle manufacturing pressing tools.

For some customers, it has increased productivity from 18 strokes per minute to 27 strokes per minute while reducing bounce and damage to the pressing tool.
