Abstract
The invention relates to a hydromechanical drive system for at least one press ram of a cutting and/or forming press, at least one drive cylinder being connected to a following kinematic chain. This kinematic chain is designed in such a way that a complete ram stroke, i.e. a downward motion and an upward motion, is effected during a single piston stroke in only one direction. In addition, the proposed drive system has mechanical controlled synchronization.
