The common faults and maintenance methods of pneumatic punching machines are as follows:
Travel issues:
Reason for malfunction: damaged travel limiter, uneven or worn guide pin or ball screw.
Solution: Replace the travel limiter, guide pin or ball screw. one
Punching machine shaking or jamming:
Reason for malfunction: The punch press counterweight loses balance, the counterweight position is improper, the slider return is uneven, the slider guide seat or screw guide rail is damaged or loose.
Solution: Correct the punch weight, readjust the slider return, replace damaged slider guide seats or screw guides.
Poor lubrication or insufficient hydraulic rod and pressure:
Reason for malfunction: insufficient lubricating oil, oil pipe rupture or loose connections, improper adjustment of oil pressure.
Solution: Add sufficient lubricating oil, replace oil pipes or connectors, and readjust oil pressure.
Punching machine not working or insufficient working force:
Reason for malfunction: Damaged electromagnet, power failure, malfunction of pneumatic solenoid valve.
Solution: Replace the electromagnet, troubleshoot the power supply, and replace the faulty pneumatic solenoid valve.
Insufficient or unstable air pressure:
Reason for malfunction: Insufficient gas supply, pipeline blockage, gas source or pipeline leakage.
Solution: Check if the air source is stable, adjust the air source pressure, check if the air source is dry, clean the filter, and check if the air path is unobstructed. two
Unstable itinerary:
Reason for malfunction: Failure of pneumatic or mechanical components.
Solution: Check if the air circuit is stuck or leaking, and if the lubrication system is clean
