Abstract
A workpiece processing apparatus comprises a base member formed with a hydraulic chamber fillable with liquid, a punch and a piston. The hydraulic chamber has a workpiece processing chamber and a hydraulic-pressure generation chamber. The punch is movable between an initial position which is apart from the workpiece processing chamber and a received position at which the punch is partially received in the workpiece processing chamber. When the punch is moved from the initial position to the received position, the punch presses the workpiece into the workpiece processing chamber. The piston is partially received in the hydraulic-pressure generation chamber and receives a pressing force directed into the hydraulic-pressure generation chamber in a course of movement of the punch from the initial position to the received position, and the piston is moved in accordance with the pressing force and increases hydraulic pressure of the liquid.
