ABSTRACT:
A power press in which low inertia motors with speed control circuitry are connected to a cam which acts upon a lever or cam follower which, in turn, cooperates with a force-storing element which has a spring action and is coupled, e.g. by the same lever, to the tool of the press. Accordingly, in the rotation of the cam, the force-storing means stores potential energy which is transformed into kinetic energy of the ram in another region of the cam at which part of the energy can be delivered to the low inertia motors. Hence the speed control of the motor will, in part, regulate the rate at which the stored force is delivered to the workpiece.
