Description

technical field [0001] The invention relates to a radial arc pressure height adjusting device of a numerical control plasma cutting machine, which belongs to the field of height adjustment of cutting guns of the numerical control cutting machine. Background technique [0002] CNC plasma cutting machine adopts the cutting method of high-energy melting cutting with plasma arc as the heat source. It has the advantages of fast cutting speed, narrow heat-affected zone of the incision, small deformation of the workpiece, and good cutting accuracy. It is widely used in medium and thin metal plates. Automated cutting. During the cutting process, it is very important to control the height distance between the plasma cutting torch and the workpiece, which not only causes changes in the arc parameters, but also directly affects the cutting quality. At present, domestic CNC plasma cutting height control is generally realized by analog circuits. Although the circuit is simple and low in...
