How To Maintain And Repair Punching Machines

Mechanical maintenance
1500-2000 hours of maintenance and upkeep
Testing and adjusting the oil output and pressure detection function of lubricating grease. Check and make necessary adjustments to the functions of the air system filter, oil feeder adjustment valve, and water impurities testing. 3. Check the set value of the air pressure switch and test and adjust the pressure detection function. Check and adjust the set value and measured value of the module height indicator switch. Check and adjust the chain wheel, chain, transmission shaft, worm gear and other components of the mold height adjustment device for looseness, abnormalities, and chain tension. Disassemble the upper cover of the gear transmission box, inspect the wear and looseness of internal components and key positions, clean the oil groove, replace the lubricating oil, and check the operation status, noise, and vibration testing. Testing and adjusting the oil discharge and pressure at the injection points of various parts of the transmission system. Test points and necessary adjustments for the piston action, brake angle, brake clearance, and wear of the brake disc of the brake release mechanism.
Measure the gap between the sliding guide rail and the guide path, check the friction surface, and make adjustments and corrections if necessary. Add manual lubricating grease to flywheel bearings and inspect pipelines, joints, etc. Test and inspect the operation status of the balance cylinder and its oil lubrication system oil circuits, joints, etc. Testing and inspection of insulation impedance of motor circuits and electrical operating circuits. Test the accuracy of the entire machine (verticality, parallelism, comprehensive clearance, etc.), and adjust and correct it if necessary. Clean the appearance and accessories of the punching machine, check the points, and adjust the fastening screws and nuts of the mechanical feet (foundation) for locking and horizontal inspection if necessary. Clean, maintain and inspect the pump, pipeline valves, and other components of the lubrication and oil supply system. Clean and maintain the pneumatic components and pipelines of the air system, as well as conduct action testing and inspection.
Test the performance of photoelectric safety devices and adjust the projection angle and area for maintenance after 3000 to 4000 hours of use. Inspection, testing, and adjustment of the appearance, contact wear, and loose connection of other components in the electrical system, as well as the functions of the two degree falling rotating cam switch box and emergency stop circuit. Oil circuit cleaning, oil chamber cleaning, oil replacement, and pressure action and function testing adjustment for overload protection devices. Check and adjust the wear and tension of the V-belt of the main motor. Disassemble and disassemble the components of the brake release mechanism (excluding the flywheel) for cleaning and maintenance, clearance inspection and adjustment, and reassembly and debugging. Disassemble, clean, inspect, and reassemble the components of the balancer. Use 6000 to 8000 hours of maintenance to disassemble and disassemble the saw teeth and connecting rods, clean and maintain them, check the engagement and wear of the saw teeth and connecting rod threads, polish them, polish the engagement surface, and apply lubricating grease. Disassemble and disassemble the slider assembly (ball seat, cover, overload oil cylinder, worm gear, worm, etc.), clean and maintain it, adjust the clearance and wear surface, inspect the oil seal, and reapply lubricating grease. Disassemble, disassemble, clean and inspect the wear surfaces of the mold pad, and reassemble and test run it after reapplying lubricating grease.
