[0002] With the development of construction, it is usually necessary to cut metal plates, and then process them to make the required products. Usually, in the process of processing metal plates, a shearing machine is usually needed. A shearing machine is a machine that shears the plate with one blade moving back and forth relative to another blade. With the moving upper blade and the fixed lower blade, the breaking and separation of metal plates of various thicknesses can be achieved.

[0003] However, in the plate cutting work, the plate to be cut is pushed between the upper blade and the lower blade little by little by hand for cutting, which not only consumes manpower, but also the plate may warp during cutting, resulting in poor cutting effect. In addition, after long-term use, the blade of an ordinary plate cutting machine will become dull, and the blade needs to be manually disassembled and polished, which not only consumes manpower, but also leads to a decrease in work efficiency.
