Abstract
A punch assembly which may be provided at a punching station in a turret punch press. The punch assembly includes a striker body having a solid portion, and a punch carrier which carries a plurality of individual punches. A selectively actuable stop holds the striker body stationary, allowing the punch holder to be rotated so that a predetermined one of the plurality of punches will underlie the solid portion of the striker body. Afterwards, the entire punch assembly may be rotated to a variety of angular orientations. At any of these orientations, the ram may be actuated to cause the punch to extend downwardly below the punch assembly and through a sheet of material. The rotation of the punch assembly to different orientations allows a single punch to be used to punch holes of the shape but with differing angular orientations. The die holder receives a plurality of corresponding dies having openings therein corresponding to the punches. The die holder is rotatable to maintain constant alignment between corresponding punches and dies.
