In order to better improve the working efficiency of the four-column hydraulic press, the following preventive measures should be adopted before work:
Before the four-column hydraulic press starts to work, remove all kinds of dirt on the equipment, wipe off all stains on the four-column hydraulic press rod, maintain the flexibility of the mold shell, check the coupling of hydraulic oil pump and motor, and the coupling should be reliable. Four positioning pins, piston rod surface, mold shell, guide slider and other parts should maintain wettability. In addition, limit switches and safety protection equipment are inspected to ensure their credibility in operation.
2. The mold shell installation of the four-column hydraulic press must be carried out under the condition of power failure. Do not hit the start button, rocker and button switch. Align the left and right sides of the shells vertically, adjust the inner diameter of the shells, and do not deviate from the management center. After the mold shell is fixed, water pressure test again (pay attention to the actual operation of the electric power switch to avoid damaging the mold shell in the control switch mode).
3. Before starting the four-column hydraulic machine, the starting machine equipment should rotate at high speed for five minutes to check whether the oil in the car tank is sufficient, whether the sound of the gasoline pump is normal, and whether the hydraulic machine module, pipeline, connecting head and piston rod are leaking.
4. Start the hydraulic test of industrial equipment to check whether the working pressure is up to the pressure and whether the machine and equipment are operating normally.
5. Adjust the pressure, but not more than 90% of the rated working pressure of the four-column hydraulic press equipment, water pressure test a product workpiece, after the detection of the standard in production.
6. For different four-column hydraulic machine aluminum profile and product workpiece, in the suppression and calibration, the pressure, suppression frequency and pressure holding time of the four-column hydraulic machine should be adjusted anytime and anywhere, to ensure that the mold shell and product workpiece will not be destroyed.
