Abstract

The device has a plunger piston (2) and a pressure accumulator (3) which are connected to one another. On the plunger piston (2) is fixed the punch (13) of a tool. The pressure accumulator (3) is a piston accumulator with a gas space (20) and a liquid space (19) which is in communication with the chamber (4) via a valve arrangement. Furthermore, a pre-stroke valve (24) is integrated into the pressure accumulator (3). This device can be used to limit the degree of pressure which can be applied to the plunger piston. As a result, a tool (23) is protected independently over its total circumference against excessive closing pressure. <IMAGE>
