Abstract：

The ironing speed has an important effect on the forming quality of the whole cylindrical part in the multi-pass ironing process. In order to investigate the influence of ironing speed on the dimension accuracy of formed part, the different ironing speeds in the multi-pass ironing process were studied by the finite element numerical simulation method, and the influences of ironing speed on the dimension accuracy of formed cylindrical part were investigated by taking the actual external diameter and wall thickness deviation of part in the multi-pass ironing process as the performance indexes. The results show that the actual external diameter and wall thickness deviation of part are smaller than the theoretical values after the multi-pass ironing, and with the increasing of ironing speed, the external diameter of part increases first and then decreases, on the contrary, the wall thickness deviation of part decreases first and then increases. When the ironing speed is 15 mm·s-1, the actual external diameter of part is the closest to the theoretical diameter, and the wall thickness deviation of part is the smallest.
