Abstract：

In order to obtain tin bronze connecting rod bushing with better forming quality, the number of different spinning wheels in spinning process was simulated by finite element software Simufact. For the tin bronze cylindrical parts, the spinning processes with two and three spinning wheels were simulated on the same blank, and the comparison and analysis were conducted with inner diameter expansion amount, wall thickness deviation and ellipticity as the evaluation indexes of spinning forming quality. The results show that the inner diameter expansion amount increases from the bottom to the mouth in the two-wheel spinning process, while in the three-wheel spinning process, it decreases first and then increases. The wall thickness deviation of the two-wheel spinning is smaller than that of the three-wheel spinning, the ellipticity of the two-wheel spinning is larger than that of the three-wheel spinning, the forming quality of the three-wheel spinning is relatively stable, and the fluctuaion of the two-wheel spinning is large. Thus, the forming quality of tin bronze connecting rod bushing processed by the three-wheel power spinning is slightly better than that of the two-wheel spinning, and the former dimension accuracy is higher.
