Abstract：

The outer surface of aluminum alloy tube was extruded by the method of double-wheel radial spinning with coreless die, and a kind of tube part with exterior groove was obtained. Then, the spinning process was simulated numerically by finite element method, and the forming characteristics of blank and the influence laws of process parameters on the forming were studied in the spinning process. However, in the forming process, the material accumulation phenomenon occurred on the both sides of contact area between the outer surface of blank and the roller to form a bulge, and the material in the groove of blank flowed to other areas resulting in the reduction of wall thickness in the groove area. Furthermore, the influences of ratio ξ of applied stress to yield stress, ratio η of feeding distance of roller to wall thickness of blank and wall thickness t0 of initial tube blank on the forming quality of workpiece were studied. The results show that the moderate ξ, larger η and smaller t0 are beneficial to the forming quality of workpiece.
