Description

Technical Field

[0001] The utility model relates to an intersecting line cutting device. Background Art

[0002] A steel tube tower refers to a lattice tower frame composed of steel tubes for the main components and steel tubes or steel sections for the other components. A-type columns are often used in the construction process. The A-type column refers to two steel tubes connected at one end at a certain angle and opened at the other end by a certain distance, and a pipe fitting is connected between the two steel tubes, so that the overall A-shaped frame is required. The relative positions of the two steel tubes need to be cut with an intersecting line at a small angle, and then welded with the pipe fitting. Therefore, during the production process of this type of A-type column, it is necessary to first set the relative positions of the two steel tubes for cutting. However, the A-type column used for the steel tube tower generally uses larger-sized steel tubes, and during the cutting process, the steel tube needs to be rotated or moved along its axial direction, which has high requirements for positioning. In addition, since only a small-angle cut is required, there are also requirements for the convenience of disassembly and assembly, so it needs to be improved. Utility Model Content
