Description

Technical Field

[0001] The utility model relates to the technical field of blades, in particular to a combined shearing machine blade. Background Art

[0002] Shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear the plate. It uses the moving upper blade and the fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size.

[0003] In the existing hot-rolled plate production process, shearing is a necessary step. However, due to the residual stress inside the hot-rolled plate and the stress on the surface, it is easy to deform and bend during shearing, and vibration will occur during the shearing process. The shearing knife is not well positioned, resulting in the product not meeting the processing requirements. The length of the existing front cutter is fixed and cannot be adjusted according to the actual processing product requirements. The cutter is an integral structure. When one part is damaged, the entire blade needs to be replaced, which is relatively wasteful. Utility Model Content
