摘要

The press (10) with a hydraulically driven plunger has a mechanical transmission consisting of at least one toggle lever (12) is connected by a connecting element (15) to the hydraulic drive (11). The upper arm (13) of the at least one toggle lever has three linkages (17,18,19). The lower arm (14) of the at least one toggle lever is vertical when the plunger (100) is at its low point.
