A rotatable buffer turret apparatus (1) on which plural pairs of punches and dies to be set on a turret (3T) of a turret punch press (3) are set, includes an upper buffer turret (13) on which punch attachment holes (11) in which the punches can be set are arranged circularly, and a lower buffer turret (17) on which die attachment holes that is associated with the punch attachment holes (15) and in which the dies can be set are arranged circularly. The upper and lower buffer turrets (13, 17) are rotatably attached to a single rotary shaft (9). A diameter of the lower buffer turret (17) is made larger than a diameter of the upper buffer turret (13). The die attachment holes (15) are formed in a circular die attachment area having a diameter larger than the diameter of the upper buffer turret (13). According to the apparatus (1), a tool exchange manually operated by an operator can be done easily and efficiently. |
