PURPOSE:To prevent the change of set position due to shocks of continuous working by providing fixed holding devices and enabling to fix upper and lower dies mounted on a turret at a set angle position to the turret. CONSTITUTION:In a titled press, fixed holding devices 123 that fix upper and lower dies mounted on an upper turret 13 and a lower turret 19 allowing free rotation are attached to the uppper and lower turrets 13, 19. Above-mentioned upper and lower dies are installed so as to allow free interlocking with a rotation driving device 53 mounted on a frame 5 or upper and lower turrets 13, 19. After upper and lower dies are split just under a ram 23, the device 123 is loosened and the device 53 performs normal and reverse rotations. The pair of upper and lower dies are changed in their angular position to the turrets by the same angle. After setting angular position, the device 123 is set to a holding state, and punching work is performed. |
