Description

Technical Field

[0001] The utility model belongs to the technical field of H-shaped steel shearing, and specifically relates to an H-shaped steel end shearing machine. Background Art

[0002] H-shaped steel is a common structural steel material, which often needs to be sheared in engineering. The shearing of H-shaped steel generally refers to the shearing of steel plates. When shearing H-shaped steel, a shearing machine (shearing machine) or a cutting machine is usually used for processing.

[0003] H-shaped steel is usually produced in standard sizes, but in actual engineering or manufacturing, it may be necessary to process it according to specific length requirements. H-shaped steel can be adjusted to the appropriate size by shearing to meet the requirements of various projects. Secondly, during the production process, H-shaped steel may have some bad parts (such as rust, deformation, etc.), which can be removed by shearing to improve the quality and availability of the material;

[0004] In the prior art, when cutting H-shaped steel, a steel plate is usually mounted on a shearing table, and an H-shaped groove of a size corresponding to the H-shaped steel is opened on the shearing table. The H-shaped steel is passed through the H-shaped groove, and the position of the H-shaped steel is adjusted so that the shearing mechanism cuts the H-shaped steel. However, due to the different sizes of the H-shaped steel, when cutting the H-shaped steel that does not match the H-shaped groove, it may be inconvenient to squeeze and position the H-shaped steel, and it is also inconvenient to further squeeze and stabilize the position close to the cutting point of the H-shaped steel, which may cause deviations in the H-shaped steel cutting process;
