Safety operation rules for hydraulic pendulum shears
First, carefully implement the relevant provisions of the "General operation Rules for forging and pressing Equipment".
Ii. The following supplementary provisions shall be earnestly implemented:
1. Before the short running test run, manual steering should be used for a working stroke, and the equipment can be started only after the confirmation of normal operation. 2, hydraulic equipment, check the oil storage tank should be sufficient. After starting the oil pump, check whether the valve and pipeline leak, and the pressure should meet the requirements. Open the valve to let air out of the system.
(ii) Work conscientiously:
1, do not shear laminated sheet, do not trim the edge of the burr edge sheet, do not shear pressure is not tight narrow sheet and short material.
2, the gap between the knife plate should be adjusted according to the thickness of the plate, but not greater than 1/30 of the plate thickness. The knife plate should be firmly fastened, the upper and lower knife plate surfaces should be kept parallel, and manual turning inspection should be applied after adjustment to avoid accidents.
3. The edge of the blade should be kept sharp. If the edge is blunt or cracked, it should be replaced in time.
4, shear, pressing device should be firmly pressed sheet, not in the state of pressure is not tight shear.
5. For equipment with hydraulic device, except throttling and cutting, other hydraulic valves are not allowed to be adjusted without permission.
1, for the thickness of the shear plate of the hydraulic pendulum shear machine, should be determined according to the "plate ultimate strength and plate thickness curve".
(three) after work, the upper knife plate should fall on the lowest position.
