摘要:

 为了满足乘用车轻量化的要求,对现有的某铝合金控制臂成形工艺参数和预锻模具进行优化。利用单一变量法并结合有限元分析软件,对预锻工序的锻造温度和模具温度进行分析,确定其对控制臂成形效果的影响规律。计算结果表明,始锻温度采用420~450 ℃、模具温度采用280~300 ℃。其次,针对锻造实验中出现的筋部折叠缺陷,采取加大预锻模具中弯臂和中心孔处筋条底部的过渡圆角的方法进行消除。最后,通过实验验证了锻造参数的合理性与模具修改方案的可行性,避免了在实际生产中出现质量缺陷。

 In order to meet the requirements of lightweight for passenger vehicles, the forming process parameters and the preforging die of aluminum alloy control arm were optimized, and the forging temperature and die temperature of the preforging sequence were analyzed by the single variable method and the finite element analysis software to determine the influence law of two parameters on the forming effect of control arm. The calculation results show that the forging process parameters with initial forging temperature of 420-450 ℃ and mold temperature of 280-300 ℃ are selected. And the neck folding defect occurred in the forging experiment is eliminated by increasing the transition rounded corner at the bottom of rib at the middle arm of preforging die and central hole. Finally, the rationality of forging parameters and the feasibility of mold modification scheme were validated by the forging experiment to avoid quality defects in actual production.
