Optimization Design of Cold Upsetting Process in Bearings Steel Ball Based on DEFROM


Article Preview

Abstract.Now the largeness of circumferential belt and 2 poles in ball billet after cold upsetting process and the consequently low material utilization ratio increase the following process time and cause a great waste. In order to obtain low allowance of ball billet, high material utilization ratio and productivity, through the research of the cold upsetting process, evaluating indicator including plumpness, roundness, cold upsetting force and volume was established, orthogonal test was designed. By the Deform simulation analysis the optimum process parameters was obtained. The results show that the optimized cold upsetting force is reduced by 35%. So the optimized process parameters has a great application value.
