Abstract：

In the process of ironing cold forming, the thinning rate is an important process parameter influencing on the dimensional accuracy of the whole cylindrical part. In order to explore the influence of thinning rate on the dimensional accuracy of ironing for cylindrical part, for the C15-c low carbon steel, the processes of ironing cold forming with different thinning rates were simulated and analyzed by finite element simulation software Simufact.forming, and the influence of thinning rate on the dimensional accuracy of cylindrical part in the ironing cold forming process was investigated by taking the outer roundness error and wall thickness deviation of cylindrical part after ironing as the evaluation indexes. The results show that with the increasing of thinning rate, the outer roundness error of cylindrical part decreases first and then increases, and the wall thickness deviation of cylindrical part increases. The variation rules of experimental result and simulation result are consistent, and the error between them is less than 10%, thus the finite element simulation has good reliability.
