As is explained, two separate but synchronised drives shape the interplay of ram acceleration, ram deceleration and the allocation of forming energy. Contrary to conventional systems, the new concept avails itself of a continuously rotating but significantly smaller flywheel to accumulate the energy.
Moreover, the solution separates the ram movement from the allocation of forming energy. This reportedly allows a fusion of the advantages of servo-driven presses with those of conventional clutch-brake systems, namely extremely short die contact times due to very high ram speeds.
The drives provide an acceleration angle (120°) that is claimed to be around eight times larger than the acceleration angle of conventional clutch-brake drive systems (10 to 15°), which allows the required delivered torque to be around one eighth of a conventional drive system.
