How to deal with common problems in bending machine processing
As an important equipment for metal sheet processing, the bending machine often encounters some problems during the processing. This article will propose corresponding solutions and suggestions to address these issues, helping operators better solve common problems in bending machine processing.
1、 Inaccurate handling of bending angles
When the bending angle processed by the bending machine is not precise, the first step is to check the accuracy and wear of the mold. If the accuracy of the mold is insufficient or severely worn, a new mold should be replaced in a timely manner. At the same time, check whether the angle sensor and control system of the equipment are working properly, and calibrate and adjust them if necessary. In addition, the skill level of operators is also a key factor affecting the accuracy of bending angles. Therefore, improving the skill level of operators is also an important way to solve this problem.
2、 Response to bending cracks and creases
Bending cracks and creases are common problems in bending processing. To solve this problem, the first step is to check whether the material and thickness of the board meet the processing requirements. Meanwhile, choose appropriate molds and process parameters to avoid excessive bending or excessive bending speed. In addition, pre-treatment of the sheet metal, such as annealing and preheating, can also improve the plasticity of the sheet metal and reduce the probability of crack formation.
3、 Equipment fracture and stuck solution
Equipment breakage and jamming may be caused by improper mold installation, excessively thick sheet metal, or excessive equipment load. The solution includes checking the installation and fixation of the mold to ensure that it is installed correctly and securely fastened; Select appropriate molds and process parameters based on the thickness of the board to avoid equipment overload; Regularly inspect the transmission components and lubrication system of the equipment to maintain its good operating condition.
4、 Troubleshooting noise and vibration issues
The noise and vibration generated by the bending machine during the processing not only affect the operating environment, but may also cause damage to the equipment. To troubleshoot noise and vibration issues, the first step is to check if the fasteners of the equipment are loose. If they are loose, they should be tightened in a timely manner. At the same time, check the wear of the transmission components and replace them in a timely manner if there are any abnormalities. In addition, the stability of the equipment base and bracket also affects the generation of noise and vibration, and it should be ensured that the base and bracket are installed firmly and smoothly.
5、 Abnormal odor and smoke treatment
Abnormal odors and smoke may be caused by equipment overheating, damage to electrical components, or burning of surface coatings on panels. Once abnormal odors and smoke are detected, the machine should be immediately shut down for inspection. Check whether the cooling system of the equipment is working properly and whether the electrical components are damaged. If there are any abnormalities, they should be replaced or repaired in a timely manner. Meanwhile, pay attention to whether the surface coating of the board is suitable for bending processing, and if necessary, replace it with a suitable board.
6、 Start stop fault repair
The starting and stopping faults of the bending machine may be caused by electrical control system faults, sensor damage, or improper operation. To solve such problems, the first step is to check whether the connection and wiring of the electrical control system are good. If there are any abnormalities, they should be repaired in a timely manner. At the same time, check the working status of the sensor and replace it promptly if there is any damage. In addition, ensure that operators are familiar with the equipment operation process and precautions to avoid malfunctions caused by misoperation.
7、 Adjustment for uneven bending edges
Uneven bending edges may be caused by uneven sheet metal, improper mold adjustment, or uneven distribution of bending force. To adjust the flatness of the bent edge, it is first necessary to ensure that the surface of the board is flat and free of warping. At the same time, adjust the position and angle of the mold to ensure that the sheet metal is subjected to uniform force during the bending process. In addition, use appropriate pressure and speed for bending to avoid uneven edges caused by excessive bending.
8、 Improvement of surface abrasion issues
Surface scratches are usually caused by friction between the contact surface of the sheet metal and the mold or equipment. To improve this issue, appropriate lubricant can be applied to the mold or contact surface to reduce friction. At the same time, regularly check the wear of the mold, and if there is any wear, it should be replaced or repaired in a timely manner. In addition, ensure that the surface of the board is clean and free of impurities to avoid scratching the surface of the board during the bending process.
In summary, dealing with common problems in bending machine processing requires starting from multiple aspects, including equipment inspection, process parameter adjustment, and improvement of operating skills. Only by comprehensively considering these factors can we ensure the smooth processing of the bending machine and the stable improvement of product quality.
