Safety operation regulations for plate shears

Operating procedures

1： Seriously implement the relevant provisions of "General operating procedures for forging equipment".

2： Conscientiously implement the following supplementary provisions:

1. Work hard before work:

1) Before the commissioning, the machine should be turned manually for a working stroke, the equipment can be started only after it is confirmed to be normal.

2) For the equipment with hydraulic device check the oil storage tank, the oil quantity shall be sufficient. After starting the oil pump, check the valve pipeline for leakage, the pressure shall meet the requirements. Open the bleeder valve to let the air out of the system.

2. In the work, we should conscientiously do the following:

1) It is allowed to shear the laminated sheet metal, trim the edge of the rough edge sheet metal, do shear the narrow short sheet metal which is tightly pressed.

2) The gap between the tool plates should be adjusted according to the thickness of the plate, but it should be greater than 1 / 30 of the plate. The cutter board shall be firmly fastened, the upper lower blade surfaces shall be kept parallel. After alignment, manual turning shall be used for inspection to avoid accidents.

3) The cutting edge of the cutter board shall be kept sharp. If the edge becomes blunt cracks, it shall be replaced in time.

4) During shearing, the pressing device should firmly press the sheet metal, it is allowed to shear under the condition of being pressed tightly.

5) For equipment with hydraulic device, except throttling valve, other hydraulic valves are allowed to be adjusted without permission.

6) The thickness of the plate cut by the hydraulic swing shear should be determined according to the curve of the relationship between the plate ultimate strength the plate thickness.

3. After working, the upper tool plate should be placed at the lowest position.

Before operation, tight protective clothing should be worn, the cuffs should be fastened, the upper lower hem should be opened, it is allowed to wear, take off change clothes near the running machine tool, wrap cloth on the body to prevent the machine being twisted. Safety helmet must be worn, braid should be put into the cap, skirt slippers are allowed.

4. The operator of plate shears must be familiar with the main structure, performance usage of the shears.

1) Plate shears are suitable for cutting various steel plates, copper plates, aluminum plates non-metallic materials whose thickness is the rated value of the machine tool, must be materials without hard marks, welding slag, slag inclusion welding seam, over thickness is allowed.

2) How to use the plate shear: adjust the blade clearance according to the thickness of the material to be cut; adjust the model clamp according to the width of the material to be cut; make 1-3 times of empty stroke before the operation of the shear, then carry out the shearing work after it is normal.

3) In case of abnormal operation of the machine in use, the power supply shall be cut off immediately the machine shall be shut down for inspection.

4) When adjusting the machine tool, the power must be cut off. When moving the workpiece, pay attention to the safety of hands.

5) All parts of the plate shears should be lubricated regularly. The operator should fill the lubricating oil once every shift, the mechanic should fill the rolling bearing once every half a year.
