Description

Technical field [0001] The invention relates to a pipeline intersecting line plasma cutting device. Background technique [0002] Among the elbows of mine steel gas pipes, mitered elbows are mostly used. Mitered elbows are welded by several joints cut with intersecting lines. At present, there are two kinds of hand-made and machine-made when cutting intersecting lines. method; manual production adopts the method of lofting and scribing first, and then manual gas cutting. The ground area is relatively large; there is still a lack of intensive small-scale production equipment with low investment and guaranteed cutting quality and production efficiency of intersecting lines. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and to provide a plasma cutting gun with a rotatable platform to realize intersecting line cutting of elbow joints, which has good cutting quality, low cost and high p...
