ABSTRACT:
A press for performing a work operation on a workpiece including a yoke defining a central bore, a ram mounted for reciprocal movement in the bore and carrying a fabricating tool on one end of the ram, an air cylinder secured to an end wall of the yoke and having a piston rod passing through the end wall of the yoke into the bore, and a force multiplying mechanism interconnecting the free end of the piston rod and the ram and operative to move the ram to a working position and thereafter multiply the force applied to the ram to facilitate the performance of the work operation. The force multiplying mechanism includes a linkage system interconnecting the free end of the piston rod and the ram and including a final link which moves into a position in proximity to the line of action of the ram as the fabricating tool reaches its working position so that subsequent movement of the link toward the line of action has the effect of multiplying the force exerted on the ram and thereby on the fabricating tool carried by the ram.
