This procedure is used to guide the operator in the proper operation and use of the equipment. Scope of application This regulation is applicable to guide the company.Hydraulic pressoperation and safe operation. Management Content
1. Operating procedures
(1) Before starting, check whether each fastener is firm, whether there are obstacles in each running part and sliding surface, and whether the limiting device and safety protection device are perfect.
(2) Before work, make an idle stroke test run for 10 minutes, check whether the buttons, switches, valves, limit devices, etc. are flexible and reliable, confirm that the pressure of the hydraulic system is normal, and the working beam can move flexibly before starting work. (3) It is strictly prohibited to use the oil cylinder over stroke.
(4) The cylinder piston is found to shake or the oil pump has a sharp sound to discharge gas.
(5) If the equipment has abnormal phenomenon or sound during work, stop the machine for inspection.
6) When working, the pressed workpiece should be placed in the middle of the working table and concentric with the spindle, and the pad should be placed smoothly.
(7) After work, turn off the working oil pump first, then turn off the control oil pump, cut off the power supply, clean the equipment, and make spot inspection records.
2. Safety operation procedures
(1) Before starting the machine, check whether the fasteners are firm, whether there are obstacles in each operating part and sliding surface, and whether the limiting device and safety protection device are reliable.
(2) It is strictly forbidden to use the oil cylinder over-stroke, and it is forbidden to process when shaking occurs during pressurization or decompression.
(3) The cylinder piston shakes or the oil pump has a sharp sound, and the gas should be discharged.
(4) It is strictly prohibited to adjust the regulating valve and pressure gauge, and the pressure gauge should be corrected regularly.
(5) Keep the oil quality of the hydraulic oil of the hydraulic press, and the working oil temperature must not exceed 45 ℃. If there is an abnormality, stop the machine.
