基于Deform的轴承钢球冷镦工艺的优化设计

Optimization design of cold upsetting process in steel bearings ball based on Defrom

现有钢球冷镦工艺生产的钢球环带、两极比较大,材料利用率不高,这不仅增加了后续加工时间,而且造成很大浪费。为了降低球坯余量,进一步节约材料,提高生产效率,通过对锥鼓形球坯冷镦工艺的研究,建立了饱满度、圆度、冷镦力、体积等评价指标,并设计正交试验,用Deform仿真分析得出合理的球坯工艺参数。结果显示,优化后的球坯冷镦力减小了35%,改进后的工艺参数具有很好的实际应用价值。

The largeness of circumferential belt and two 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,the evaluating index including plumpness,roundness,cold upsetting force and volume was established,and orthogonal test was designed.By the Deform simulation analysis,the optimum process parameters were obtained.The results show that the optimized cold upsetting force is reduced by 35%.So the optimized process parameters has a great practical application value.
