Tagalog Different measures should be taken to repair different fault causes, as follows:
1、 Die wear
If the mold is severely worn, a wear assessment can be conducted first to determine whether to repair or replace it based on the degree of wear. If the wear is light, it can be repaired by grinding, polishing, and other methods; If the wear is severe, a new mold should be replaced.
2、 Pressure system malfunction
For pressure system faults, the first step is to check whether key components such as the pressure control valve and hydraulic pump are working properly. If any components are damaged, they should be replaced in a timely manner. At the same time, it is necessary to check whether there is any oil leakage in the pressure system. If there is any oil leakage, the oil leakage point should be identified and sealed.
3、 Positioning accuracy issue
If it is found that the positioning accuracy does not meet the standard, the transmission system, guide rail, encoder and other components should be checked first. For worn or loose components, they should be repaired or replaced in a timely manner. At the same time, it is necessary to regularly calibrate the equipment to ensure that the positioning accuracy meets the requirements.
4、 Hydraulic system malfunction
Hydraulic system failures typically manifest as insufficient or unstable pressure. When dealing with such faults, the oil level and quality of the hydraulic oil tank should be checked first. If there are any problems, the hydraulic oil should be replenished or replaced in a timely manner. At the same time, it is necessary to check whether the hydraulic pump, hydraulic valve and other components are working properly. If any components are damaged, they should be replaced in a timely manner.
5、 Electrical control failure
Electrical control faults are usually related to component damage or loose wiring. When dealing with such faults, it is necessary to check whether the components inside the electrical control cabinet are damaged. If there is any damage, it should be replaced in a timely manner. At the same time, it is necessary to check whether the wiring is loose or short circuited. If there are any problems, they should be tightened or repaired in a timely manner.
6、 Inaccurate bending angle
If the bending angle is found to be inaccurate, the equipment’s parameter settings should be checked first to ensure they are correct. If the parameter settings are correct, the installation position and fastening of the mold should be checked. For molds that are improperly installed or not securely fastened, the installation position should be readjusted or tightening measures should be strengthened.
7、 Improper maintenance and upkeep
For malfunctions caused by improper maintenance and upkeep, the daily maintenance and upkeep of the equipment should be strengthened. This includes regular replacement of hydraulic oil, cleaning of hydraulic system, tightening of loose components, etc. At the same time, it is necessary to establish a sound maintenance and upkeep system to ensure that equipment is maintained in a timely and effective manner.
8、 Failure of safety protection devices
If the safety protection device fails, the working status of the safety protection device should be checked first. If there are any problems, they should be repaired or relevant components replaced in a timely manner. At the same time, regular testing and inspection of safety protection devices should be carried out to ensure their normal operation and timely triggering of protective actions.
In summary, corresponding measures should be taken to repair different causes of faults. At the same time, it is necessary to strengthen the daily maintenance and upkeep of equipment to prevent the occurrence of malfunctions.
