Safety Operation Procedures for Plate Shearing Machine

Before operation, it is required to wear tight protective clothing with cuffs fastened. The lower part of the coat shall not be opened. It is not allowed to wear, take off or change clothes beside the starting machine tool, or wrap the cloth on the body to prevent the machine from being twisted. Safety helmet must be worn, braids should be put into the hat, and skirts and slippers are not allowed.

The operator of the plate shearing machine must be familiar with the main structure, performance and use method of the shearing machine.

The shearing machine is suitable for cutting all kinds of steel plates, copper plates, aluminum plates and non-metallic plates with the thickness of the machine tool rating, and it must be the materials without hard marks, welding slag, slag inclusion and welding seam, and it is not allowed to exceed the thickness.

Use method of shearing machine: adjust the clearance of blade according to the thickness of the material to be cut; adjust the profiling or fixture according to the width of the material to be cut; make 1-3 times of empty stroke before the operation of the shearing machine, and the shearing can be carried out only after it is normal.

In case of abnormal operation of the machine during operation, the power supply shall be cut off immediately for shutdown inspection.

When adjusting the machine tool, the power supply must be cut off. When moving the workpiece, pay attention to the safety of the hand.

All parts of the plate shears shall be lubricated regularly. Each shift shall be filled with lubricating oil by the operator, and the rolling bearing shall be filled with lubricating oil by the mechanic every half a year.

After shearing, the shearing machine should be able to ensure the straightness and parallelism of the sheared plate, and minimize the plate distortion to obtain high-quality workpiece. The upper blade of the shearing machine is fixed on the tool holder, and the lower blade is fixed on the workbench. A supporting ball is installed on the worktable, so that the plate can slide on it without being scratched. The back baffle is used for plate positioning, and the position is adjusted by the motor. The pressing cylinder is used to press the plate to prevent the plate from moving during shearing. Guardrails are safety devices to prevent industrial accidents. Generally, the return trip depends on nitrogen, which is fast and has small impact.
