Dieffenbacher (Eppingen, Germany) introduces its press series featuring a short-stroke closing system and adaptive accumulator management for energy-efficient production of high-quality composite components.
Dieffenbacher short-stroke presses are designed for minimum energy consumption, high press forces and short cycle times. Presses close with small cylinders until just before the position where forming takes place. From there, large cylinders act with the corresponding press force. This makes it possible to reduce the oil volume by 88% compared with conventional concepts, the company reports. Additionally, the closing system reportedly enables individual programming of the starting position of the forming, resulting in high flexibility as well as large opening heights and accessibility for parts handling.
The adaptive accumulator management feature optimizes energy consumption by automatically determining the exact energy required for forming during the first press strokes. For subsequent production cycles, the hydraulic drive accumulator is charged only to the corresponding required pressure level. All settings are determined automatically by the machine control system, reducing the load on the machine to a minimum.
Through the short-stroke closing system and adaptive accumulator management, Dieffenbacher says its customers increase the energy efficiency of their production and avoid unnecessary system losses during pressure relief after forming, significantly reducing cooling water requirements.
