Tagalog CNC bending machine is a widely used equipment in the metal processing industry, which can complete the bending task of sheet metal with high precision and efficiency. However, like all mechanical equipment, CNC bending machines may also encounter various faults during long-term operation. Understanding how to identify and handle these common faults is crucial for ensuring stable equipment operation, improving production efficiency, and ensuring operational safety.
###Common fault identification
1. * * Reverse valve malfunction * *: The reverse valve cannot reverse normally or the reverse action is slow, usually due to poor lubrication, damaged springs, oil stains or impurities blocking the sliding part, and other reasons.
2. * * Hydraulic system malfunction * *: If the hydraulic system has no pressure, the sliding block is fast and slow, and the pause time is too long, it may be caused by the electromagnetic coil of the proportional relief valve, the plug valve or main valve core is stuck, the damping hole is blocked, and other reasons.
3. * * Abnormal slider movement * *: If the slider returns to normal and fast forward is normal, but the folding board is weak when manually lowering slowly, it may be due to insufficient filling, incomplete opening of the filling valve, and other reasons.
###Fault handling
1. * * Troubleshooting of directional valve * *:
*Check if the oil mist eliminator is working properly and if the viscosity of the lubricating oil is appropriate.
*If necessary, replace the lubricating oil and clean the sliding part of the directional valve.
*If the spring is damaged, it should be replaced; If the directional valve is severely worn, consideration should be given to replacing the entire directional valve.
2. * * Hydraulic system fault handling * *:
*Check if the solenoid coil of the proportional relief valve is charged and if the voltage meets the requirements.
*Remove the overflow valve, clean and reinstall it.
*Check if the plug valve and main valve core are stuck, and if the damping hole is blocked.
*If the three-phase power supply adjustment causes the motor to reverse, the power supply phase should be readjusted.
3. * * Abnormal handling of slider movement * *:
*Check the oil level in the tank to ensure that there is sufficient oil above the filling port.
*Modify system parameters to reduce fast forward speed.
*Clean the filling valve and reinstall it to ensure that the valve core is flexible and free.
###Summary
Identifying and handling common faults in CNC bending machines requires operators to have a certain level of professional knowledge and experience. In daily operations, strict adherence to operating procedures and regular maintenance and inspection of equipment should be carried out to ensure that the equipment is always in good working condition. Once abnormalities or malfunctions are found, the machine should be immediately shut down and troubleshooting and handling should be carried out according to the above methods. At the same time, strengthen communication and cooperation with professional maintenance personnel to ensure that faults can be resolved in a timely and effective manner.
