**Common faults during the machining of CNC bending machines with twisted shafts**
As an important equipment in the modern metal processing field, the stability and reliability of the torsion axis CNC bending machine are crucial for production efficiency and product quality. However, in the actual machining process, some common faults may also occur in the torsion axis CNC bending machine. This article will provide a brief introduction to these common faults, so that users can identify and take corresponding measures in a timely manner.
1、 Hydraulic system malfunction
The hydraulic system is one of the core components of the torsion axis CNC bending machine. Common hydraulic system failures include oil pump damage, hydraulic valve failure, and oil cylinder leakage. These faults may cause the machine to malfunction or the working pressure to be unstable.
2、 Electrical control system malfunction
The electrical control system is another important component of the torsion axis CNC bending machine, and its failure may cause problems such as machine failure to start, parameter setting failure, and inaccurate motion control. Common electrical control system failures include power failure, PLC control module failure, sensor failure, etc.
3、 Mechanical structure issues
The mechanical structure of a torsion axis CNC bending machine is the foundation for its stable operation. Common mechanical structural problems include bearing wear, guide rail deformation, and poor gear meshing. These issues may lead to unstable machine operation, inaccurate positioning, or abnormal noise.
4、 Positioning accuracy issue
Positioning accuracy is one of the important indicators to measure the performance of a torsion axis CNC bending machine. If there is a problem with the positioning accuracy of the machine, it may lead to the machining size of the workpiece not meeting the requirements. The issue of positioning accuracy may be caused by loose transmission mechanisms, worn guide rails, encoder failures, and other reasons.
5、 Mold wear and adjustment
The mold is a key component of a twist axis CNC bending machine for bending operations. Prolonged use or improper adjustment may lead to mold wear or damage. Mold wear may lead to inaccurate bending angles and decreased surface quality of the workpiece.
6、 Bending angle error
Bending angle error is one of the common quality problems in the machining process of twist axis CNC bending machines, which may be caused by improper mold adjustment, unstable hydraulic system pressure, electrical control system failures, and other reasons. Bending angle errors may cause the workpiece to fail to meet design requirements.
7、 Abnormal processing speed
Abnormal processing speed is one of the common faults in the machining process of a torsion axis CNC bending machine, which may manifest as the machine running too fast or too slow. This may be caused by electrical control system malfunctions, hydraulic system issues, or mechanical structure issues. Abnormal processing speed not only affects production efficiency, but may also have adverse effects on workpiece quality.
8、 Twisted shaft transmission failure
The torsion shaft transmission system is one of the core components of the torsion shaft CNC bending machine, responsible for realizing the bending action of the workpiece. Common torsion shaft transmission faults include bending of the torsion shaft, gear wear, and loose transmission chain. These faults may cause unstable transmission, unsmooth bending movements, or inaccurate bending angles.
For the common faults mentioned above, users can take the following measures to prevent and deal with them:
1. Regularly maintain and inspect the hydraulic system to ensure the normal operation of components such as oil pumps, hydraulic valves, and oil cylinders.
2. Regularly inspect the various functions of the electrical control system, such as power supply, PLC control module, and sensors, to ensure their normal operation.
3. Regularly inspect and adjust the mechanical structure, such as the wear of bearings, guide rails, and gears, and replace or repair them in a timely manner.
4. Regularly calibrate the positioning accuracy of the machine to ensure that the machining dimensions of the workpiece meet the requirements.
5. Regularly inspect and adjust the molds to ensure their accuracy and surface quality, and replace severely worn molds in a timely manner.
6. Regarding the issue of bending angle error, it can be solved by adjusting the mold, optimizing hydraulic system parameters, or checking the electrical control system.
For the problem of abnormal processing speed, the electrical control system, hydraulic system, and mechanical structure can be inspected to identify the problem and repair it.
8. For torsional shaft transmission faults, the wear of components such as the torsional shaft, gears, and transmission chain can be checked and replaced or repaired in a timely manner.
In summary, there may be various common faults during the machining process of the torsion axis CNC bending machine. Users should regularly maintain and inspect various components of the machine, promptly identify and solve problems, and ensure the stable operation of the machine and product quality. At the same time, users should also pay attention to the daily maintenance and upkeep of the machine to extend its service life.
