The drive device comprises an electrical direct drive (118) for driving the plunger (114).

A crank press with an adjustable stroke comprises a press frame having a frame slideways therewithin with a slider reciprocatively movable therealong and supported by a pneumatic cylinder. In order to significantly increase a working force, a length of the working stroke and efficiency, the crank press further comprises: at least two mutually synchronized crank drives configured for reciprocatively moving the slider along the frame slideways, a lever-crosspiece mechanism having at least one pair of threaded guide stanchions secured within the frame bed, a crosspiece slidably mounted on the guide stanchions atop the slider, at least two two-arm levers hingedly connected to the slider supportadly on the crosspiece, at least one pair of crosspiece stop nuts engaged with threads of the guide stanchions and configured for arresting the cross-piece at the moment of applying a force to the slider by the lever and a switching arrangement for slider reversal with regulation of its stroke.

A mechanical press, with at least one drive shaft having a driver that is eccentric with respect to a shaft axis, and a sliding block. The sliding block is driven by the driver to perform a forcibly guided movement. During an execution of a pressure stroke, the sliding block is guided on at least one sliding surface on the pressure-input side opposite to a pressure-input-side surface of a slide guide. The sliding block has a sliding surface on the pressure-output side lying opposite to the pressure-input side surface, this surface being guided on a pressure-output-side surface of the slide guide, wherein the sliding surface on the pressure-input side of the sliding block has a concave or convex curvature. The sliding surface on the pressure-output side of the sliding block has the opposite concave or convex curvature, respectively.
