Abstract：

When the tube part is strongly antispun, the rotating roller directly contacts with the tube part, and the selection of spinning roller parameters largely determines the forming quality of tube part. For tube part of QSn70.2, taking the forming quality as the evaluation index, the offset antispinning of the tube part was simulated by Simufact, and the parameters of spinning roller were optimized by the grey correlation method to obtain the influences of spinning roller parameters on the forming quality of tube parts. The results show that the order of influence of the spinning roller parameters on the forming quality of antispinning tube part is spinning roller working arc radius >spinning roller axial offset > spinning roller angle. Furthermore, the optimal parameters of spinning roller are axial offset of 5 mm, working angle of 18° and working arc radius of 5 mm. The optimized combination of spinning roller parameters is verified, and the forming quality of tube part is significantly improved.
