Small pressure faults and repairs of press brakes
press brakes are a commonly used metal processing equipment. As the use time increases, some small faults will occur. This article will introduce the common small pressure faults of press brakes and their repair methods.
1. Insufficient pressure
When the pressure of the press brake is insufficient, it may cause the failure to complete the required processing. At this time, it is necessary to check whether the pressure regulator of the press brake is correctly set and whether the bottom dead point is correctly adjusted. If none of the above methods can solve the problem, you can try to replace the hydraulic oil or clean the hydraulic system.
2. Unstable pressure
When the pressure of the press brake is unstable, it may cause deviations in processing. At this time, it is necessary to check whether the hydraulic oil is sufficient and whether the hydraulic system leaks. If there is no abnormality in the inspection, you can consider replacing the hydraulic oil filter.
3. Excessive pressure
When the pressure of the press brake is too high, it may cause damage to the equipment. At this time, it is necessary to check whether the pressure sensor in the hydraulic system is working properly and whether there is any part in the hydraulic system that hinders the flow. If none of the above methods can solve the problem, you can consider replacing the hydraulic pump or cleaning the hydraulic system.
4. Incomplete pressure release
When the pressure of the press brake is not completely released, it may cause processing residue. At this time, it is necessary to check whether the pressure sensor in the hydraulic system is working properly, and whether there is a situation in the hydraulic system where the pressure is not completely released due to the valve being stuck. If the above methods cannot solve the problem, you can consider replacing the hydraulic valve or cleaning the hydraulic system.
In short, the press brake is a high-precision equipment that requires regular inspection and maintenance to maintain its normal working condition. If you encounter a small pressure fault, you can check and repair it according to the above methods to ensure the stable operation of the equipment.
