ABSTRACT:
A piezo-electric actuator operated press in which piezo-electric actuators are employed as punch driving sources, and, with a workpiece held between an upper and lower die set, the punches are driven by the piezo-electric actuators to punch the workpiece; the punches and the piezo-electric actuators are built in the respective die sets, and the movable one of the die sets is coupled to a die shifting mechanism, so that it is driven to a die opening position or a die closing position, whereby the workpiece can be smoothly fed in and taken out of the press.
