Description

Technical Field

[0001] The utility model relates to the technical field of plasma cutting, in particular to a plasma cutting machine gun head. Background Art

[0002] Plasma cutting machines can be used with different working gases to cut various metals that are difficult to cut with oxygen cutting, especially for non-ferrous metals. Its main advantage is that when cutting thin metals, plasma cutting speed is fast, especially when cutting ordinary carbon steel thin plates, the speed can be several times that of oxygen cutting, the cutting surface is smooth, the thermal deformation is small, and there is almost no heat-affected zone. When workers are cutting, they need to manually hold the corresponding cutting machine gun head and start it by pressing to achieve the cutting operation.

[0003] When cutting, not all operating positions can be easily processed. For example, when cutting in small crevices, gaps, grooves and inside devices, workers are required to rotate their bodies to adjust the angle and position of the gun head so that they can focus on the points that need to be cut. Therefore, a method is needed to easily adjust the angle of the gun head to avoid the need for workers to frequently adjust positions and facilitate processing. Utility Model Content
