Description

Technical Field

[0001] The invention relates to the technical field of steel section welding, and in particular to an automatic cutting device of a plasma cutting machine. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structure weight. It is a commonly used building material in the construction industry. The horizontal steel plate of the H-shaped steel is called the web, and the vertical direction is called the wing plate. A group of wing plates and web plates are welded together and are called T-shaped steel.

[0003] Before welding H-beam, the whole plate needs to be cut into plates of the required size. Currently, flame cutting is mostly used. However, excessively high temperatures during the cutting process can cause the plate to bend and deform, resulting in gaps in the plate during welding, making the welding unstable. In addition, even plasma cutting cannot achieve automatic cutting, and the left and right sides of the cut plate are different, resulting in deformation. Summary of the invention
