Safe operation measure of four column hydraulic machine

1, before the operation, should first clean up all kinds of debris on the mold, wipe any dirt on the hydraulic rod.
    2, hydraulic machine operator must be trained to master the equipment performance and operation technology, in order to operate independently..
    3, the hydraulic press to install the mold must be in the case of power failure, no collision start button, handle and foot on the foot switch.
    4, installed under the mold, adjust the die gap, do not allow the unilateral off center, confirmed again after fixing the die pressure.
    5, hydraulic machine before the first boot device idle for 5 minutes, and check oil level is sufficient, the pump sound is normal, the hydraulic unit and pipes, joints, whether there is leakage of piston.
    6, adjust the working pressure, but should not exceed 90% of the rated pressure of the device, press a piece of work, after passing the test.
    7, start the equipment pressure test, check whether the pressure to work pressure, whether the equipment is normal and reliable, with or without leakage.
    8, for different hydraulic machine profiles and workpiece, press fit, correction, should be adjusted at any time the pressure and pressure of the press, the number and time of pressure, and ensure that no damage to the mold and workpiece.
    9, is strictly prohibited in the press at the same time, the work of percussion, stretching, cutting, bending, twisting and other operations.
    10, hydraulic machine is completed, the power should be cut off, the hydraulic rod will wipe clean, good lubricating oil, will die and workpiece clean, tidy.
    11, hydraulic press machine, welding, welding around are not allowed to smoke, do not store flammable and explosive materials. Fire prevention measures.
    12, hydraulic machine is completed, the power should be cut off, the hydraulic rod will wipe clean, good lubricating oil, will die and workpiece clean, tidy
