Abstract
A disc support 23 is provided under a lower turret 21 to support the lower turret 21 against the impact thereto. The disc support 23 includes a movable block comprising a through-hole 77 through which scraps are discharged and a press cylinder 79 to push up a lower tool 19 for forming. In a punching operation, the through-hole 77 is arranged in the working area and scraps are discharged from the through hole 77. In a forming operation, the press cylinder 79 is arranged in the working area and pushes up the lower tool 19 to project above a pass line for a workpiece. Since the lower tool 19 is positioned below the pass line, the workpiece W cannot be damaged. Further, the workpiece W is not obstructed by the lower tool 19 when the workpiece W is positioned in the working area and the turrets are rotated, thus forming is properly performed.
