<p>PCT No. PCT/JP89/01175 Sec. 371 Date Jul. 10, 1990 Sec. 102(e) Date Jul. 10, 1990 PCT Filed Nov. 17, 1989 PCT Pub. No. WO90/05601 PCT Pub. Date May 31, 1990.A turret punch press includes an upper and lower turrets for respectively supporting a plurality of punches and dies; the punches are arranged two-dimensionally in a punch mounting regions on the upper turret and the dies are arranged two-dimensionally in a die mounting region on the lower turret. The turret punch press further includes a ram and a striker for striking the punches. The striker is provided on a bottom of the ram so as to be movable in two horizontal directions above the punches indexed in a processing region. In the turret punch press, when the turret is indexed in the processing region, many punches and dies are simultaneously indexed in the processing region. Thus, by moving the striker in two horizontal directions above the punches indexed in the processing region, many successive punch operations can be quickly performed without intermediate rotation of the turrets.</p> |
