Introduction to the scheme of metal laser cutting machine cutting pipe

Metal laser cutting machines often need to cut pipes in production. So what solutions does the metal laser cutting machine have for cutting pipes? Let's give you a brief introduction.　　 1. Numerical control cutting technology Numerical control cutting is a high-volume, high-efficiency and high-quality cutting production method for pipes. The core of CNC cutting is the CNC cutting system. At present, the quality problems existing in the laser tube cutting process such as overburning of the cutting point of the parts, overburning of the corners of the parts, inclination of the cutting surface, and deformation of the circle when cutting round parts or failure to close, etc., directly lead to serious waste of the tube and cutting production low efficiency.　　 CNC cutting technology is the cutting control software of the index control system to provide advanced cutting technology and rich cutting experience, so that the cutting operators can achieve high-quality and high-efficiency CNC cutting through the proficient use of the control system.　　2. Professional tube nesting technology. CNC laser tube cutting has high cutting efficiency and programming nesting is more complicated. If used improperly, it will cause tube waste and low cutting efficiency. Through professional pipe cutting and nesting software, pre-program drawing, nesting, and blanking on the computer to generate NC cutting programs, and then perform full-stroke automatic laser cutting and blanking of large-length metal pipes. Professional pipe nesting software is the basis and prerequisite for realizing large-volume, high-efficiency and high-quality cutting production of CNC pipe cutting machines. 3. Pipe cutting process. When the pipe is cut (especially for the square pipe with small pipe diameter), the molten slag adheres to the inner wall of the pipe, and most of the heat generated by the cutting is absorbed by the workpiece. When the cutting density is high, the pipe tends to overheat. The corners and the four corners of the square tube are burnt, which seriously affects the quality of the cut, and even cannot be cut. For such problems, the following can be used: (1) The laser cutting head with a height sensing follow-up system can ensure that during the cutting process, the height of the cutting nozzle and the surface of the workpiece remains unchanged (the focus remains unchanged), so that the cutting effect does not follow the workpiece The surface changes are affected; (2) The method of increasing the oxygen pressure (6-8Mpa); Through the software to increase the sharp corner synthesis speed. 4. Full-stroke automatic laser cutting and blanking of large-length metal pipes For the process requirements of full-stroke automatic laser cutting and blanking of large-length metal pipes, a unique dual-drive pneumatic chuck rotating mechanism (active shaft W, driven shaft) is adopted in the mechanical structure. Axis W1), the left driving axis W axis pneumatic chuck rotating mechanism is fixed, clamps the pipe, and the pipe is cut through the machine X, Y, W movement, the right driven axis W1 pneumatic chuck rotating mechanism It can move along the axis of the workpiece with the worktable, which can realize the full-stroke automatic laser cutting and blanking of large-length metal pipes.　　 Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment.
