Description

Technical Field

[0001] This utility model relates to the field of steel profile processing technology, and in particular to V-shaped cut production equipment for bending and welding square steel pipes. Background Technology

[0002] Steel processing refers to various cutting, grinding, drilling, and welding processes performed on steel to meet the needs of different projects and products. During the welding process, to improve the quality of the weld and thus increase its strength, the steel is usually cut with a V-shaped notch.

[0003] Current V-shaped notch processing equipment typically performs V-shaped notches by directly cutting the material in one step using a cutting machine, as disclosed in application number CN202421094230.4, which describes a V-shaped notch cutter for steel processing. When the steel is bent 90 degrees and then welded, especially in steel pipe processing, the connection is only formed by the butt weld on the side plate, resulting in low structural strength.

[0004] During production, our company discovered through research that when performing V-shaped cuts on the pipe fitting 15, if a portion of the top plate of the pipe fitting 15 is retained, such as... Figure 4 As shown, the top plate is cut at the corresponding V-groove (along the cutting line 18) to form two broken bent plates 19, forming as shown. Figure 4 The structure shown allows for welding of the bent pipe fitting 15. The two bent plates 19 bent into the pipe fitting 15 can be welded together, and the butt joint formed by the V-groove on the side plate of the pipe fitting 15 can be welded together. This results in a 90° bend with better structural strength. However, due to the lack of corresponding professional equipment, the two bent plates after cutting need to be bent manually, which is not only laborious but also has low production efficiency. Utility Model Content
