PTS is a new tool system that can be customized to vertical press machines and is essentially designed to substitute the standard tool system. In short, PTS is offering additional strength and controlled prestressing of the die set compared to a standard tool system. Consequently, PTS would offer unique possibilities for improving the service life of the forming die and the high reusability of the prestressing tool system itself.
Depending on the type of press and machine maker, PTS consists of a housing that is clamped directly to the press table. The die set may be preassembled before being mounted into the PTS assembly. Radial prestressing is provided by the high-strength stripwound container while controlled axial prestressing of the die stack is ensured with a special-designed top lid.
The graphic illustration to the right is a principal layout of PTS, which originally was developed for horizontal press machines. An implementation of PTS for a vertical press would be subject to customization in each case including both analytical calculations and a customized tool design.
