DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The pipeline 75 is used to transport the gas from the gas source to the nozzle of the cutting head. The material and sealing of the pipeline are very important to ensure that the gas will not leak or be contaminated during the transportation process. Generally, stainless steel pipes or high-quality plastic pipes are used, and well-sealed joints are used at the connection parts. The gas bottle 73 includes oxygen bottles, nitrogen bottles, argon bottles, etc. These gas sources provide pure gas for cutting. The purity of the gas has a great influence on the cutting quality. For example, when cutting stainless steel, the use of high-purity nitrogen can effectively prevent the oxidation of the material and ensure the quality of the cutting edge. After being adjusted by the gas flow controller 712, it can accurately control the flow of the auxiliary gas. According to factors such as the thickness of the cutting material and the cutting speed, the gas flow needs to be adjusted. For example, when cutting thicker carbon steel, appropriately increasing the oxygen flow rate can increase the cutting speed, but too large a flow rate may cause slag to splash, so it is necessary to accurately adjust it through a gas flow controller to supply gas to the cutting position at the lower end of the laser gun 9 along the inclined tube 713 to blow away the slag, protect the cutting area and cool the material.
