In order to reduce the cropping force and enhance the cropping cross-section quality, a new type of cropping machine is proposed in this paper. The basic structure and working principle of the cropping machine are introduced. Based on D'Alembert's principle, the vibration equations of the cropping machine along the Y direction, the X direction and around X, Y, Z axes are built in detail and the motion curves of the vibration body in all directions are also obtained. The amplitude frequency response characteristic curve of the vibration body in the Y direction is given and the resonance frequency of the vibration body in the Y direction is about 7.94 rad/s. The cropping experimental results show that the cropping force acted on the metal bar is low and the cross-section quality is very high.
