Numerical control laser cutting technology of metal pipe

Large length metal tube full stroke automatic laser cutting blanking

   For large metal pipe full stroke length automatic laser cutting blanking process requirement, on the mechanical structure adopt unique dual drive pneumatic chuck rotation mechanism (drive shaft W, driven shaft W1), on the left side of the drive shaft W axis rotation mechanism fixed, the pneumatic chuck will pipe holding it, through the machine X, Y, W movement of pipe cutting processing, on the right side of the rotation mechanism with the driven shaft W1 pneumatic chuck table along the axial movement of workpiece, which can realize large length metal pipe full automatic laser cutting of material.

CNC cutting technology

   CNC cutting is a mass, high efficiency, high quality cutting production mode, the core of CNC cutting is CNC cutting system.At present, the quality problems in the laser tube cutting process, such as over-firing of the cutting point of the parts, over-firing of the corners of the parts, inclined cutting surface, and circular deformation or failure to close when cutting round parts, directly lead to serious waste of the tube and low cutting efficiency.

   CNC cutting technology is an exponential control system of cutting control software to provide advanced cutting technology and rich cutting experience, so that cutting operators through skilled use of the control system, to achieve high quality, high efficiency of CNC cutting.

Professional pipe nesting technology

   Due to high cutting efficiency, programming nesting is more complex, if not used properly, it will cause pipe waste and low cutting efficiency.Through the professional pipe cutting and nesting software on the computer in advance drawing, nesting, cutting segmental programming, NC cutting program, and then a large length of metal pipe full stroke automatic laser cutting blanking.Professional pipe nesting software is the basis and prerequisite for CNC pipe cutting machine to achieve mass, high efficiency and high quality cutting production.

Pipe cutting technology

   Due to the pipe cutting (especially for square pipe with small diameter), dissolved slag is attached 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 large, it will often cause the pipe overheating, corners and square pipes overburn, seriously affecting the cut quality, and even can not be cut.(1) The laser cutting head belt height sensor 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 will not be affected by the changes of the workpiece surface;(2) Methods of increasing oxygen pressure (6-8mpa);(3) Improve the synthesis speed of sharp corners through software.
