Location：Pipe laser cutting machine: fault handling of abnormal focus position of cutting head
Click： Time：2023/3/29 21:21:40
In the laser cutting operation of pipes, the focal position of the cutting head is the core parameter that determines the cutting quality. Any abnormality can directly lead to problems such as rough cutting, slag hanging, and failure of pipe perforation, affecting production efficiency and product qualification rate. Accurately identifying the cause of faults and implementing targeted treatment is the key to ensuring the stable operation of equipment.
The identification of faults with abnormal focus positions requires a comprehensive judgment based on cutting effectiveness and equipment feedback. From the perspective of cutting quality, if there is a conical deviation where the incision is wide at the top and narrow at the bottom or narrow at the bottom and narrow at the top, it is mostly due to the focus being too high or too low; If sparks splash and scatter during perforation, perforation time is significantly prolonged, or continuous arc breaks occur during thick walled pipe cutting, the focus position should be prioritized for investigation. In addition, if the device control system prompts related alarms such as "abnormal focus detection sensor", it is also necessary to verify the focus position parameters by associating them.
Pipe laser cutting machine The investigation of fault causes should follow the principle of "mechanical first, electrical control later, simple first, complex later". On the mechanical level, sticking of the focus adjustment mechanism is a common cause. Long term high-frequency operation may lead to dust accumulation on the adjustment screw, lubrication failure, or slight deformation of the guide rail, limiting the precise movement of the focus axis. Secondly, collision of the cutting head is a factor that is easily overlooked. Deviation in pipe clamping or slight shaking during feeding may cause the cutting head to be impacted, resulting in a deviation of the focal reference position. At the electronic control level, drift of focus position sensor signals, abnormal data from servo motor encoders, or incorrect modification of focus parameters within the CNC system may all cause position deviation.
Targeted processing needs to be implemented step by step. Firstly, conduct a basic inspection: after turning off the device power, manually push the focus adjustment shaft to check for any jamming. If there is, disassemble the adjustment mechanism, clean the oil and dust on the screw, and reapply special lubricating grease; At the same time, check if there are any collision marks on the cutting head casing. If there is any deformation, contact a professional for calibration. Next, carry out parameter calibration: enter the equipment control system, call the focus position calibration program, use standard test specimens for trial cutting, and fine tune the focus value according to the quality of the cutting surface until the best cutting effect is achieved; If the sensor alarms, the zero point of the sensor needs to be recalibrated to ensure accurate signal transmission.
After the fault is resolved, a preventive mechanism should be established: check the flexibility of the focus adjustment mechanism before daily operation, and clean and lubricate it once a week; Regularly review the focus parameters within the CNC system to avoid accidental modifications; Ensure precise positioning when clamping pipes to reduce the risk of cutting head collisions. Through the closed-loop process of "precise identification system troubleshooting targeted processing normalized prevention", the problem of abnormal cutting head focus position can be efficiently solved, ensuring stable operation of the equipment.
