In order to reduce the cropping force and enhance the cropping cross-section quality, a new type of croppingmachine 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, X direction andaround X, Y, Z axis are built in detail and the motion curves of vibration body in all directions are also obtained. Theamplitude frequency response characteristic curve of the vibration body in Y direction is given and the resonance angularfrequency of vibration body in Y direction is about 7.94 rad/s. The cropping experimental results show that the croppingforce acted on the metal bar is low and the cross-section quality is very high.
