Abstract: Double rollers clamping spinning is a energy and material saving type process. To obtain the effects of roller parameters on double rollers clamping spinning, based on ABAQUS/Explicit, finite element model of double rollers clamping spinning for right-angle flange is established in case of unrotating workpiece. The model is verified by the experiment, and then used to analyze the double rollers clamping spinning process for right-angle flange. And then the effects of roller round radius, distance between two rollers and roller feed rate on the double rollers clamping spinning process are obtained. The results show that the roller round radius has no obvious effects on the spinning moment, while the increase of roller round radius can reduce the quality of flange. The distance between two rollers has obvious effects on the spinning moment only at the initial forming stage, and with the increase of distance between two rollers the spinning moment reduces. However, the forming quality reduces with the increase of distance between two rollers. With the increase of roller feed rate, the forming quality is improved, but the spinning moment increases. According to the above results, the proper roller parameters during the double rollers clamping spinning are obtained.
