The steel pressing part 1 is provided with an outer surface layer, and the outer surface layer is made of an elastically deformable material. In specific implementation, the elastically deformable material of the outer surface layer of the steel pressing part 1 may be rubber, cloth or plastic. When shearing many steels, many steels can be once only stabilized to the material that can elastically deform. The cold shearing machine can stably shear a plurality of steel materials at the same time during subsequent processing.
