The use of plate shear bending machine can not let the machine has been in full load condition. And after a period of time after the use of machine tools for maintenance, like a car, the maintenance, the replacement parts, so that the best way to achieve the use of plate shear.
The return cylinder pressure, 1 low shear bending machine will produce on the edge of the return cylinder is inflated to rise slowly. Remove the protective cap and air valve cap, fitted with pneumatic tools, the other end of the gas filled with nitrogen gas cylinders (no oxygen), open the gas filling tool, slowly open the valve of the nitrogen gas bottle, pay attention to the gas filled pressure gauge. Turn off the load cylinder stop valve immediately to 6.0MPa. Close the inflation tool, open the inflation tool, install the valve cap and the protective cap.
2, cutting machine bending machine blade gap adjustment. When the gap is adjusted, the locking bolt is loosened, and then the handle is rotated to the required calibration value, and then the screw is locked tightly. Ball valve for measuring the gap between the upper and lower blades edge clearance. Specific method is to a single trip, when the next frame to the bottom dead center is rapidly rotating ball valve turn off the oil, the rest stop to bottom dead center. And then continue to open and close the ball valve, so that the upper tool carrier on the whole trip up, at this time can be measured by cutting edge clearance.
3, plate bending machine can not afford to bend the oil pressure, no action on the knife. Electromagnetic reversing valve electrical plug bad contact, check the electrical plug, the electromagnetic reversing valve spool is debris stuck dead or brushed surface does not move. Combination valve of the valve core sealing port with debris and do not play a closed role. Combined valve in the throttle hole blocking. Check and.
4, shearing machine bending machine tool return slowly or not back to the top dead center, the tool carrier and the pressing cylinder action sequence coordination. Check and adjust to the rated pressure.
Often to their own use of shear bending machine bending machine can effectively reduce the failure rate of plate cutting machine.
