Claims

[Scope of utility model registration request]

In order to shear the strip during one movement, it has an upper cutter device and a lower cutter device respectively provided in the frame, and a drive device for vertically moving the front-loading upper cutter device with respect to the lower cutter device. , in a pendulum shear in which the frame is adapted to swing together with the upper and lower cutter devices in synchronization with the line speed of the strip, the upper cutter device includes an upper cutter, an upper tool rest that supports the upper cutter; It has a reinforcing block for reinforcing the upper tool rest and a device that presses the upper tool rest in the same direction as the side pressure that the upper tool receives when shearing the strip, and the lower tool device has a reinforcing block for reinforcing the upper tool rest, and a device that presses the upper tool rest in the same direction as the lateral pressure that the upper tool receives when shearing the strip. a stand, a lower cutter fixed to the lower cutter, a device for pressing the lower cutter in the same direction as the side pressure that the lower cutter receives during strip shearing, and a gap between the upper and lower cutters that is adjustable. and a wedge device for shearing the strip, and the drive device includes a connecting rod that connects a crankshaft provided in the frame and the reinforcing block, and the crankshaft is configured to A pendulum shear characterized by being rotated in a direction opposite to the direction of the swinging force just before.
