ABSTRACT:
An apparatus is provided to form a workpiece to a net position and pierce a hole in the workpiece. The apparatus includes a base having an inner and outer slide assembly mounted thereon for reciprocal movement. Both the inner and outer slides include a cylinder and a rod extending therefrom. The apparatus includes a compressed spring attached between the inner slide and base, and coupled to the rod of the outer slide as to operate to equalize the inner slide about the workpiece. The rod of the outer slide impacts the base to drive a form against the workpiece to form the workpiece to a net position. The rod of the inner slide actuates to drive a punch through the workpiece to pierce the workpiece.
