Numerical Simulation of Double Rollers Clamping Spinning Process for Flanging
Double rollers clamping spinning (DRCS) is a new process to form thin-walled rotary shell parts with complex flange, which adopts two rollers to clamp the workpiece in the forming. Using FE simulation code ABAQUS/Explicit, the 3D simulation model of DRCS process for flanging is established, and the whole DRCS process and material deformation have been simulated. Distribution of equivalent stress, equivalent strain and wall thickness of flange in the DRCS process are obtained. And then, the effects of roller feed rate and flange length on the formed flange part are studied. Results show that equivalent stress, equivalent strain and reduction in wall thickness increase with the decrease of roller feed rate, while increase with the increase of flange length. The results obtained in this paper can provide the references to determine and optimize the new spinning process parameters.
