Correct operating procedures and precautions for hydraulic pendulum metal shears
First, earnestly implement the relevant provisions of the forging equipment operating procedures.
Second , conscientiously implement the relevant supplementary regulations as follows :
( 1 ) Before doing the work seriously :
1 , before the short-term test , you should first manually arrange the work , confirmed the normal boot device.
2. For the hydraulic equipment of the equipment , the number of oil storage tanks should be enough to check. After starting the pump, check whether there is any leakage , the valve and pipeline pressure should meet the requirements. Play with the outdoor air valve system.
( 2 ) Work hard :
1. Instead of cutting the composite sheet , instead of cutting the edge of the flash metal sheet , there is no shear pressure to tightly narrow and short board materials. Metal shears
2. The gap between the blades should be adjusted according to the thickness of the sheet , but not more than 1/30 . Blades should be tightened , upper, right panel holding the knife parallel , Artificial barring check after reset , in order to avoid accidents.
3. The knife board should maintain a sharp edge , if it is dark or split , it should be replaced in time.
4. The shearing pressure loading device should firmly press the sheets , and the shearing conditions should not be tight.
5. For hydraulic equipment with equipment , except for throttle reduction, other hydraulic valves shall not be adjusted without authorization.
6 , hydraulic tilting shears cutting thickness of the metal plate , should be determined based on the relationship of FIG ultimate strength and thickness of the metal plate.
