The main technical problems of laser cutting are introduced and analyzed
1, large length of metal pipe full automatic laser cutting cutting
For the large-length metal pipe full-stroke automatic laser cutting cutting process requirements, in the mechanical structure using a unique dual-drive pneumatic chuck rotation mechanism (drive shaft W, driven shaft W1), the left side of the active shaft W-axis pneumatic chuck Rotating mechanism is fixed, the pipe clamped, through the machine X, Y, W movement of the pipe cutting, the right side of the driven shaft W1 pneumatic chuck rotation mechanism can work along the table along the workpiece axial movement, can be large Length of metal pipe full range of automatic laser cutting cutting.
2, CNC cutting technology
CNC cutting is a large number of pipe, high efficiency, high-quality cutting production methods, CNC cutting is the core of CNC cutting system. At present, the quality problems in the cutting process of laser pipe are as follows: the part of the cutting point is burned, the corner of the part is burned, the cutting surface is tilted, and the circular part is cut or can not be closed, which leads directly to the serious waste and cutting production of the pipe low efficiency.
CNC cutting technology refers to the CNC system of cutting control software to provide advanced cutting technology and a wealth of cutting experience, so that cutting operations through skilled use of the control system to achieve high-quality, high-efficiency CNC cutting.
3, professional pipe material nesting technology
CNC laser tube cutting due to high cutting efficiency, programming nesting more complex, if used improperly, it will cause waste of pipe and cutting efficiency is low. Through the professional tube cutting nesting software on the computer in advance to draw, nesting, cutting sub-programming, generate NC cutting procedures, and then large-length metal pipe full automatic laser cutting cutting. Professional pipe material nesting software is to achieve CNC tube cutting machine large quantities, high efficiency, high-quality cutting production of the basis and prerequisites.
4, pipe cutting process
As the pipe cutting (especially for small diameter square pipe), the slag attached to the tube wall, cutting most of the heat generated by the workpiece absorption, cutting density is large, often lead to overheating pipe, corner and square tube four A corner burned, seriously affecting the quality of incision, or even impossible to cut. Such a problem can be used: (1) laser cutting headband height sensing servo system to ensure that the cutting process, the cutting nozzle and the workpiece table plane height remains unchanged (focus unchanged), so that cutting results do not work with the workpiece (2) increase the oxygen pressure method (6-8Mpa); (3) through the software to improve the sharp angle synthesis speed.
