ABSTRACT:
In the upper portion of a frame there is mounted a drive for producing oscillating motion, and a pressing device in kinematic connection therewith. A punch is fixed in the lower portion of the pressing device to operate on a workpiece. Below is mounted a cross piece for reciprocating motion in the vertical direction, including a portion which extends beyond the limits of said frame, which is provided with a vertical through groove adapted to receive the rod of an article being processed. A table is disposed on the upper surface of the cross piece, for reciprocal movement in a horizontal plane. The table is provided with an opening coaxial with the portion of the groove disposed within the punching zone.
