ABSTRACT:
A wedge actuated cutting and/or forming tool comprises a frame including spaced guide portions. A fixed platen is mounted on the frame and a movable platen is mounted on the guide portions of the frame for reciprocation toward and away from the fixed platen. A wedge is supported for lateral reciprocation with respect to a backup and thereby effects reciprocation of the movable platen. The wedge is driven by a hydraulic cylinder and switch means are provided for regulating both the separation between the movable platen and the fixed platen at the closest point and the total stroke of the movable platen. The frame further includes a hydraulic reservoir which receives a substantial quantity of hydraulic fluid. By this means the structure of the reservoir and the hydraulic fluid therein tend to stabilize the tool and dampen vibrations caused by the operation thereof.
