The Combination Makes the Difference – New Voith CSH Die Cushion Drive and PSH Press Drive Save Up To 80 % Energy
The die cushion drive with double-acting die cushion is ideal for forming processes involving complex geometries. The advantages are obvious: The CSH provides exceptional repeatability. In addition, the CSH is freely programmable in terms of speed, force and position control, and acceleration. The result is not only increased process variability, operators also benefit also from increased productivity while simultaneously improving the quality of the parts produced. How is that possible? The accelerated die cushion adjusts to the position-time curve of the ram and, in contrast to a single-acting die cushion, reduces tool impact on the workpiece. This improves surface quality, protects the machine and tool, and prevents damage such as cracks and creases on the workpieces.
The Combination Sets New Standards
The PSH press drive from Voith is known for its very high energy savings. The intelligent control system permits a very flexible use of the press. The PSH therefore guarantees the best possible matching of power and speed to the pressing process. Thus, the press only uses as much energy as required by the relevant process phase.
With the combination of a PSH press drive and the new CSH die cushion drive, Voith has now developed a system that sets new standards in the world of servo presses: Press operators can save up to 80 % energy in the future and improve total cost of ownership (TCO) while simultaneously increasing productivity. The unlimited programmability of the drive concept gives operators new capabilities when it comes to demanding forming processes. Both the PSH and the CSH can be scaled up easily into the megawatt range.
