Technical Field

[0001] The utility model relates to the field of cutting equipment, in particular to a square billet cutting device capable of improving end face quality. Background Art

[0002] Billets are square or rectangular steel billets produced by billet opening machines for secondary firing materials or directly for subsequent forging purposes. After being output from the billet opening machine, the billets need to be cut into the required fixed lengths and enter the cooling bed for cooling. Before entering the cooling, the billets need to be cut. The commonly used billet cutting method is to use a hydraulic shearing machine. The billets cut by the hydraulic shearing machine are subject to greater pressure, which can easily cause the billets to bend, affecting subsequent processing. In addition, the end faces of the billets cut by the hydraulic shearing method are prone to distortion and deformation, and the end face quality is poor. Therefore, it is particularly necessary to develop a billet cutting device that can improve the end face quality. Summary of the Invention
