Based on the motion principle of mechanical swing guide rod, a new spinning forming method for elliptical cross-section thin-walled parts is proposed. The mathematical model of forming principle and forming trajectory of elliptical cross-section thin-walled parts was established by graphical analysis method, and the accuracy of the model was verified by numerical calculation. Based on this model, the motion relationship between the wheel and the parts in the forming process is studied. The wheel rotation radius of different sizes is selected to simulate the motion trajectory of the wheel in the forming process of the elliptical cross-section thin-walled parts. It is found that when the wheel rotation radius is closer to its lower limit value, it is conducive to the forming of the elliptical cross-section parts, which provides a theoretical basis for the general process research and application of the relevant sections and the development of machine tools.
