In this paper, the crop shear of Qiangang silicon steel preparation unit is studied, and the structural characteristics of the crop shear are analyzed. Combined with the technical data of the crop shear, the cutting force of the crop shear and the calculation of the force energy parameters of the pinch device are given. And the driving equipments are selected. The finite element analysis model of the crop shear＇s frame is established by using 3D software. The stress field, displacement field and safety factor of the frame are analyzed. According to the design standards to test the results of the test for the rack design and optimization to provide the basis.
