【摘要】 以汽车丁字臂零件为对象,分析了原有锻造工艺过程,根据金属塑性流动理论和设计方法,改进了丁字臂零件锻造成形工艺。采用有限元数值模拟软件对其改进后制坯工艺过程、金属填充状态进行模拟分析,同时对比分析了改进前后终锻等效应变分布和成形载荷。结果表明改进后的工艺提高了零件的材料利用率和模具寿命。模拟结果与实验结果吻合,对实际生产起到了指导作用。更多还原

【Abstract】 In this paper,the original forging process of automobile T-shaped part is analyzed.According to the metallic plastic flow theory and design methods,the forging forming process of the T-shaped parts is improved.There were simulated and analyzed that the process of blank making,the filled state of metal.Besides,Effective strain fields and the load of before and after Improving of T-shaped part were compared.It is indicated that improved process can improve material utilization ratio and die life.The simulation is in agreement with experimental results.It has provided a theoretical basis to guide the practical production.更多还原
