standard operation of hydraulic swing plate shears:
I. carefully implement the relevant provisions of the general operating procedures for forging equipment
II. Carefully implement the following relevant supplementary provisions:
function order exceeding 1 (I) before work:
1. 90 and 180 stripping clamps, etc. shall be manually cranked for a working stroke before empty operation test run, and the equipment can be started only after it is confirmed to be normal
2. For equipment with hydraulic device, check that the oil in the oil storage tank should be sufficient. After starting the oil pump, check whether there is leakage in the valve and pipeline, and the pressure shall meet the requirements. Open the deflation valve to discharge the air in the system
(II) do it carefully in work:
1. It is not allowed to cut laminated sheets, trim the edges of rough edged sheets, or cut loose narrow sheets and short sheets
2. The clearance between the cutter plates shall be adjusted according to the thickness of the plate, but shall not be greater than 1/30 of the maximum plate. The cutter board shall be fastened firmly, and the upper and lower cutter boards shall be parallel. After adjustment, manual turning shall be used for inspection to avoid accidents
3. The blade edge shall be kept sharp. If the blade edge becomes blunt or cracks, it shall be replaced in time
4. During shearing, the pressing device shall firmly press the sheet, and it is not allowed to shear under the condition of loose pressing
5. For equipment with hydraulic device, which can be cured by ultraviolet light within 15 seconds, except throttle valve, other hydraulic valves are not allowed to be adjusted privately
1. The thickness of the sheet cut by the hydraulic pendulum shear shall be determined according to the relationship curve between the ultimate strength of the sheet and the sheet thickness
