At present, the main problems and difficulties of pipe laser cutting machine in the process of laser pipe cutting are as follows: the part cutting point is burned, the part corner is burned, the pipe cutting surface is inclined, and the circle is deformed or cannot be closed when cutting circular parts. This situation will directly lead to material waste and low production efficiency. Using advanced numerical control system can solve such problems. The so-called numerical control pipe cutting technology refers to the advanced pipe cutting technology and rich pipe cutting experience provided in the pipe cutting control software of the numerical control system, so that the pipe cutting operators can achieve high-quality and high-efficiency numerical control cutting through skilled use of the control system. Numerical control laser tube cutting technology is a large-scale, efficient and high-quality cutting production method of pipes. The core of numerical control tube cutting is the numerical control tube cutting system.
During the pipe cutting process, the molten slag is easy to adhere to the inner wall of the pipe during processing, and most of the heat generated by cutting is absorbed by the workpiece. When the cutting density is large, it often causes the pipe to overheat, and the corners and four corners of the square pipe to overheat, which seriously affects the cutting quality and even cannot be cut. For such problems:
1. Methods of increasing oxygen pressure;
2. Improve the synthesis speed of sharp corners through software.
3. The cutting head of the pipe laser cutting machine is equipped with a height sensing servo system, which can ensure that the height of the nozzle and the surface plane of the workpiece remains unchanged (the focus remains unchanged) during the cutting process, so that the cutting effect will not be affected with the change of the workpiece surface.
