Abstract

A processing apparatus for processing a workpiece by transferring the workpiece between a ram and a die block. At least one recessed die of a plurality of dies molds the workpiece into a bottomed tubular shape by a punch. A punch, among a plurality of punches, that has entered the recessed die exits from the recessed die with the formed workpiece being attached to the punch, together with the workpiece. Since the workpiece is transferred from the die block to the ram when the punch exits from the die, a step of moving the ram forward relative to the die block to transfer the workpiece from the die block to the ram can be omitted accordingly.
