After shearing, the shearing machine should be able to ensure the straightness and parallelism of the shearing surface of the sheared sheet material, and reduce the plate distortion as far as possible to obtain high-quality workpieces. The upper blade of the plate shearing machine is fixed on the tool rest and the lower blade is fixed on the working table. A pallet ball is installed on the worktable so that the plate is not scratched when sliding on it. The rear stop is used for plate positioning, and the position is adjusted by the motor. The press cylinder is used to press the plate to prevent it from moving during shearing. Guardrails are safety devices to prevent accidents at work. The return journey is usually made by nitrogen, with high speed and low impact.
