Abstract
A punching and stamping machine has a movably guided die plate frame, in which an eccentric shaft for the drive of the die is simultaneously disposed. The die plate frame is moved by means of a plate cam which is directly coupled with the eccentric shaft As a result, a forcibly guided movement is achieved between the die and the die plate which, with respect to the workpiece to be machined, is superimposed such that the die carries out only minimal movements with respect to the workpiece and therefore, particularly in the case of a hollow-cylindrical workpiece, permits the machining from the interior side to the exterior. As a result of this forced guidance, very high operating speeds can advantageously be achieved with a high precision.
