Workpiece i.e. strip material, punching device, has upper tool arranged in retaining plate, where decoupling of upper tool against downward movement of retaining plate is triggered by control unit after completion of punching operation
The device (1) has a cyclically pressurizable upper tool (2) arranged in a retaining plate (4) and guided into a guide plate (5). A decoupling of the tool against downward movement of the retaining plate is triggered by a control unit (10) after completion of a punching operation. The control unit includes a control element (11) and another control element (12). The latter control element is moved from a pressure position of the control unit in which the latter control element pressurizes the tool into a release position in which the tool is decoupled by application of pressure. An independent claim is also included for a method for punching of a workpiece i.e. strip material.
