Numerical Simulation of Influences of Process Parameters on the Spinning Moment and Quality of Double-Roller Clamping Spinning

Abstract:

In order to obtain the influences of process parameters on double-roller clamping spinning (DRCS) process, the finite element (FE) numerical simulation is performed. Firstly, on the basis of nonlinear FE analysis software ABAQUS/Explicit, the FE model for the DRCS process is established. Secondly, the reliability of the FE model is verified by the experiment results. Finally, using the verified FE model, influences of roller feed rate, initial wall thickness and contact length on the spinning moment, maximum wall thickness difference and flange difference of the DRCS process are studied. The results show that when roller feed rate increases, both the spinning moment and flange difference will increase, however, the maximum wall thickness difference will decrease. And the increase of initial wall thickness can cause all the spinning moment, the maximum wall thickness difference and the flange difference to increase. Furthermore, the increase of contact length can cause all the flange width, maximum wall thickness difference and spinning moment to increase, as well as the increase of the difference between the flange width and the contact length. In addition, it is concluded that the flange width has a maximum value for the definite blank. The results can provide the theoretical basis for determining the process parameters of DRCS.
