摘要
介绍了一种新型金属管材激光切割设备。该机采用激光头轴向移动,由电动卡盘带动工件旋转的方法合成切割轨迹,实现了分段式切割,对不同直径的工件无需更换卡块,并采用辅助空气冷却的切割方法实现了低氧压切割,耗氧量比传统设备节省了2/3。该设备最大单程切割长度1000mm,切割表面粗糙度≤6.3μm,孔位精度为±0.1mm/m,辅助氧气压力≤0.15MPa。
Laser processing equipment for metal tube-cutting is introduced. the cutting track is formed by the laser head moving along axis combined with the workpiece turning droven by an electric chuck circumvolve, thus the subsection cutting for the workpiece with different radius could be easily realized without changing the chuck. Low oxygen pressure cutting by air cooling can reduce the consumed oxygen by 2/3 oxygen compared with traditional ones. Its maximum single cutting length is 1 000 mm, the cutted surface roughness Ra≤6.3 μm, position accuracy ±0.1 mm/m, and oxygen pressure ≤0.15 MPa.
