In the production process of steel doors and windows, shearing machines are often required to cut the plates. During the processing, shearing machines often need to cut plates of equal length multiple times.

[0003] Some shearing machines in the prior art can realize automatic feeding with high efficiency, and can also pull plates of different thicknesses, thereby improving practicality. However, due to the different materials, processing methods and transportation conditions of metal plates, the metal plates are prone to bend in the middle or warp at both ends.
