Abstract：

In order to solve the problem of material swelling and accumulation under a large feeding ratio in the spinning process, a roller spinning manufacturing process with a planetary arrangement was proposed. First, according to the trajectory of roller in the space and the assumption that the tube blank was a semi-infinite body, the contact equation between roller and tube blank during the roller spinning process was established, according to the principle of coordinate conversion, the projected area of the contact area between roller and tube blank under each coordinate plane of dynamic coordinate system was obtained, and the mathematical model of roller spinning was established by the assumption that the average pressure in the forming zone was approximately equal to the unit contact pressure in the deformation zone when the steel ball was pressed into the semi-infinite body of space. Secondly, based on the ABAQUS/Explicit platform, a three-dimensional numerical model of roller spinning was established, and the numerical simulation of multiple process parameters was carried out by changing feeding ratio f, thinning amount tp and feeding angle β. The results show that the theoretical calculation results for the three-dimensional components of spinning force are in good agreement with the finite element simulation data, and the proposed calculation method of the three-dimensional numerical model for the roller spinning provides a reference for design of spinning process and equipment.
