Gas Burner Valves angle bevel laser cutting process

To complete the total Gas Burner Valves angle of 31.5 ° bevel cut, to be produced in Figure 2 cut-precision tooling, tooling hydraulic positioning pitch pitch Gongyi scale manipulation within ± 0.01mm, shroud segment selection process after welding, dealt with a full circle around the ramp beyond Æ 3000mm. The Gas Cooker valves problem can not be processed.
Adjust the coupling of laser processing parameters, the laser power P = 1260W, cutting speed v = 1.4m / min, generally oxygen (99.8% purity) as his assistant, gas, gas pressure is 0.08MPa, you can accomplish the viewpoint bevel laser cutting kerf width of about 0.18mm.
Laser head nozzle spacing change from the Gas Burner Safety Valve and the amount of gas burner valve have a significant impact on the quality of cut, the nozzle is too far away from the workpiece make kerf widening, roughness progress, nozzle spacing too easily with the workpiece attack bump. Spacing from the workpiece handling between 0.5 ~ 0.8mm, preferably cut after the cavity surface quality. The amount of coke (ie, the orientation of the laser focus within the workpiece) about 1mm, ensuring smooth cut, does not render the entrance slit Burner Valves, made an outstanding appearance and processing quality.
