Tagalog **Problems to be paid attention to for fault diagnosis and troubleshooting of CNC bending machine molds**
During the use of CNC bending machine molds, it is inevitable that faults will occur. Timely fault diagnosis and elimination are the key to ensuring the efficient operation of the equipment. When conducting fault diagnosis and troubleshooting, attention should be paid to the following aspects:
1、 Die wear inspection
Mold is the core component of CNC bending machine, and its wear condition directly affects the processing quality and equipment performance. Therefore, in fault diagnosis, the first step is to check the wear of the mold. Observe whether there are obvious scratches, dents, or wear on the surface of the mold, and if necessary, use professional instruments for measurement. Once severe mold wear is found, it should be replaced or repaired in a timely manner.
2、 Pressure system malfunction
The pressure system is an important component of CNC bending machines, and its failure can directly cause the equipment to malfunction. When diagnosing faults, the pressure system should be checked for issues such as oil leakage, insufficient pressure, or unstable pressure. At the same time, it is necessary to check whether key components such as pressure control valves and hydraulic pumps are working properly. For pressure system faults discovered, timely maintenance or replacement of relevant components should be carried out.
3、 Positioning accuracy issue
The positioning accuracy of CNC bending machines is the key to ensuring machining quality. When diagnosing faults, attention should be paid to checking whether the positioning accuracy of the equipment meets the requirements. If it is found that the positioning accuracy does not meet the standard, it may be caused by problems with the transmission system, guide rail, or encoder. A detailed inspection should be conducted on these parts to identify the cause of the malfunction and repair it.
4、 Hydraulic system malfunction
The hydraulic system is an important power source for CNC bending machines, and its failure can cause the equipment to malfunction or malfunction. When diagnosing faults, it is necessary to check whether the oil level and quality of the hydraulic oil tank are normal, and whether components such as hydraulic pumps and valves are working properly. At the same time, attention should also be paid to checking the sealing and smoothness of hydraulic pipelines. For hydraulic system malfunctions, timely cleaning, oil replacement, or maintenance of related components should be carried out.
5、 Electrical control failure
The electrical control system of a CNC bending machine is the key to achieving automated operations. When diagnosing faults, attention should be paid to checking whether the components inside the electrical control cabinet are damaged, whether the wiring is loose or short circuited, and other issues. At the same time, it is necessary to check whether signal input devices such as sensors and encoders are working properly. For electrical control faults, they should be investigated and repaired according to specific circumstances.
6、 Inaccurate bending angle
During the machining process of CNC bending machines, if the bending angle is not accurate, it will seriously affect product quality. When diagnosing faults, the first step is to check whether the equipment’s parameter settings are correct, including bending angle, bending speed, etc. At the same time, it is necessary to check the installation position and fastening of the mold. If any problems are found, the parameters should be adjusted or the mold should be reinstalled in a timely manner.
7、 Improper maintenance and upkeep
The daily maintenance and upkeep of equipment is crucial for preventing malfunctions and improving equipment lifespan. When diagnosing faults, attention should be paid to checking the maintenance records and status of the equipment. If improper maintenance or lack of necessary maintenance measures are found, timely rectification and strengthened management should be carried out.
8、 Inspection of safety protection devices
There are certain safety risks during the operation of CNC bending machines, so the equipment is equipped with various safety protection devices. During fault diagnosis, these safety protection devices should be inspected and tested to ensure their normal operation and timely triggering of protective actions. For safety protection device malfunctions or failures discovered, immediate repair or replacement of relevant components should be carried out.
In summary, when diagnosing and troubleshooting the faults of CNC bending machine molds, it is necessary to pay attention to the above issues. Through meticulous inspection and comprehensive troubleshooting, the cause of the malfunction can be quickly identified and effective measures can be taken to repair it, ensuring that the equipment returns to normal operation and improving production efficiency.
