Maintenance of precision punch

A. Maintenance items should be implemented every 1500-2000 hours of use:

　　1. Test and adjust the oil volume and pressure detection function of the lubricating grease.

　　2. The function of the filter of the air system, the adjustment valve of the oil feeder and other functions, and the water impurity test inspection and necessary adjustment.

　　 3. Air pressure switch setting value check and pressure detection function test and adjustment.

　　4. Check and adjust the setting value of the mold height indicating switch and the actual value.

　　5. Check and adjust the sprocket, chain, drive shaft, worm gear and other parts of the mold height adjustment device for looseness, abnormality and chain tension.

　　6. The upper cover of the gear transmission box is removed, the internal parts are worn and the keys are loosened, and the oil tank is cleaned, the lubricant is replaced, and the running status, noise, and vibration are tested.

　　7. Test and adjust the oil volume and pressure of the oil injection point of each part of the transmission system.

　　8. Test points and necessary adjustments of the piston action of the brake release mechanism, the brake angle, the release brake clearance and the wear of the pad.

　　9. Gap measurement and friction surface inspection of sliding guide rail and guide path, adjust and correct if necessary.

　　10. Add manual lubricating grease to flywheel bearings and check pipelines and joints.

　　11. Test and check the operation status of the balance cylinder and its oil lubrication system, joints, etc.

　　 12. Test and check the insulation resistance of the motor circuit and electrical operation circuit.

　　 13. Test the accuracy of the whole machine (perpendicularity, parallelism, comprehensive clearance, etc.), adjust and correct if necessary.

　　14. Clean the appearance and accessories of the punch, check points and fix the screws of the mechanical feet (foundation), and adjust the locking of the nut and level inspection if necessary.

　　15. Cleaning, maintenance and inspection of the lubrication system, pipeline valves, etc.

　　 16.Pneumatic components, pipelines, etc. of the air system are cleaned, maintained, and tested.

B. Maintenance items should be implemented every 3000-4000 hours of use

　　17. Performance test of photoelectric safety device and test adjustment of projection angle and area.

　　18. The appearance of parts of the electrical system, contact wear and loose connection, etc., check, test and test, check and adjust the function of the two-degree rotating cam switch box and the emergency stop circuit.

　　19. Oil circuit cleaning of overload protection device, oil chamber cleaning, oil renewal, pressure action and function test adjustment.

　　20. Check and adjust the abrasion and tension of the V-belt of the main motor.

　　 21. Disassembly and decomposition of the various parts of the brake mechanism (without the flywheel), cleaning and maintenance, clearance inspection and adjustment, and assembly and re-commissioning.

　　 22. The other parts of the balancer are disassembled and disassembled, cleaned and inspected, and reinstalled and debugged.

　　 C. Maintenance items that should be performed every 6000-8000 hours of use

　　23. Disassemble and decompose the saw tooth connecting rod, clean and maintain, check the occlusion and wear of the saw tooth and connecting rod thread, and polish, polish the occlusal surface and apply grease.

　　24. Slider assembly (ball seat, cap, overload hydraulic cylinder, worm gear, worm, etc.) disassembly, cleaning and maintenance, clearance adjustment and wear surface, oil seal inspection and re-lubricating grease.

　　25. Disassemble, disassemble and clean the mold pad, check the wear surfaces, re-apply grease, and assemble and test.
