Abstract：

In order to get high forming quality of cylindrical part, cylindrical part forming processes of power spinning and ironing were analyzed by finite element numerical simulation. For tin-bronze cup part, two different forming technologies of the same blank were simulated by software Simufact. The inner diameter expansion amount, external roundness error, straightness error of outer axis, straightness error of inner axis and length of bell mouth of formed connecting rod bushing were regarded as evaluation indexes of forming quality, and the reliability of simulation was verified by test through selecting the best forming process.The results show that comparing with the power spinning with three rotating wheels and three times consecutive ironing of tin-bronze parts, the size accuracy of ironing process is slightly higher than that of the power spinning process，and the bell mouth formed by the ironing process is shorter. Thus, the ironing process has higher material utilization and is suitable for mass production of single-type connecting rod bushing.
