Research on the compound spinning process technology of thin-walled cylindrical parts with circumferential ribs

The spinning forming technology represented by thin-walled cylindrical parts with circumferential ribs is an urgent demand for the rapid development of high-tech industries such as aerospace. This paper presents a spinning process method, which is a combination of reverse spinning and stagger spinning. Firstly, the finite element model is established by setting reasonable parameters, and the distribution law of strain and stress is obtained by simulation in stage 1 and 2 . Secondly, the influence of different processing factors on the forming quality is obtained. In this paper, the optimal process parameters for thin-walled cylindrical parts with circumferential ribs are as follows: the wall thickness thinning rate is 60%. The parameters can be used when spinning similar thin-walled cylindrical parts with circumferential ribs.
