Tagalog How to deal with common problems in the operation of downward moving CNC bending machines
1、 Angle adjustment and operation
When adjusting and operating the angle of a downward moving CNC bending machine, it often encounters some problems. Here are some suggestions to address these issues:
1. Ensure machine accuracy: Regularly check and adjust the accuracy of the machine tool, including the clearance between the slider and guide rail, the fit between the screw and nut, etc., to ensure that all performance indicators of the machine tool meet the requirements of use.
2. Correct selection of mold: Select the appropriate upper and lower molds based on the material, thickness, and required bending angle of the workpiece. When the mold is severely worn, it should be replaced in a timely manner to ensure bending accuracy.
3. Fine angle adjustment: During the bending process, the CNC system fine tunes the angle to achieve the predetermined bending angle of the workpiece. When adjusting the angle, it is important to ensure that the workpiece is placed smoothly to avoid any deviation.
2、 Material issues after bending
The material problems after bending mainly manifest as workpiece deformation, uneven creases, etc. To address these issues, the following measures can be taken:
1. Optimize process parameters: Adjust bending speed, pressure, and other process parameters based on the material and thickness of the workpiece to reduce material deformation and uneven creases.
2. Use auxiliary fixtures: During the bending process, auxiliary fixtures such as pressure plates and stoppers can be used to improve the stability of the workpiece and reduce deformation after bending.
3. Post treatment measures: For workpieces that have already undergone deformation, post-treatment can be carried out through heat treatment, correction, and other methods to restore them to the predetermined shape.
3、 Abnormal noise and vibration treatment
The downward moving CNC bending machine may produce abnormal sounds and vibrations during operation, which may be caused by various reasons. The following are suggestions for addressing these issues:
1. Check the lubrication system: Ensure that the lubrication system is working properly, replace the lubricating oil regularly, and maintain good lubrication of all parts of the machine tool.
2. Tighten loose parts: Check whether all parts of the machine tool are tightened. If any looseness is found, tighten it in a timely manner to avoid abnormal noise and vibration.
3. Troubleshooting the source of the fault: Identify and eliminate the specific abnormal noise and vibration phenomena, such as adjusting the clearance of the screw, replacing severely worn components, etc.
4、 Start and stop faults
Starting and stopping faults may affect the normal operation of the CNC bending machine. To address these issues, the following measures can be taken:
1. Check the power supply and electrical components: Ensure stable power supply, check if the electrical components are intact, such as fuses, relays, etc. If there is any damage, they should be replaced in a timely manner.
2. Check the control system: Check whether the CNC system is running normally. If there is a malfunction, contact professional personnel for repair in a timely manner.
3. Operating standards: Follow the correct sequence of start and stop operations to avoid proceeding to the next step before the machine tool is completely stopped, in order to reduce the possibility of malfunctions.
In summary, in response to the common problems in the operation of the downward moving CNC bending machine, we need to start from the aspects of angle adjustment and operation, material problems after bending, abnormal noise and vibration treatment, as well as start and stop faults, and take corresponding measures to respond and handle them. By continuously optimizing process parameters, strengthening equipment maintenance and management, and improving the skill level of operators, the efficiency and bending quality of CNC bending machines can be effectively improved, and production costs can be reduced.
