Claims

[Claims for Utility Model Registration] (1) A hydraulic cutter that is provided with a cushion capable of absorbing the pressing force from the cut piece at the position where the cut piece of the workpiece being cut is pressed by the movable cutter at the tip of the piston. Mechanism to prevent cut pieces from flying away. (2) The mechanism for preventing the cut pieces from flying off in a hydraulic cutter according to claim 1, wherein another cushion is provided on the piston behind the movable cutter so that the cut pieces can be held between the pair of cushions. (3) The mechanism for preventing cut pieces from flying off in a hydraulic cutter according to claim 1 or 2, wherein the cushion is made of an elastic body. (4) The mechanism for preventing the cut pieces from flying off in a hydraulic cutter according to claim 3, wherein the cushion surface against which the cut pieces are pressed has an uneven surface. (5) The mechanism for preventing cut pieces from flying off in a hydraulic cutter according to claim 3, wherein the cushion is molded with a notch. (6) The mechanism for preventing cut pieces from flying away from a hydraulic cutter according to claim 3, wherein the cushion is formed with a hollow space. (7) The cut piece of the hydraulic cutter according to claim 1, wherein the cushion comprises a pressing plate against which the cut piece is pressed, and a compression spring capable of absorbing the pressing force from the cut piece acting on the pressing plate. Anti-jump mechanism.
