摘　　要：针对轴箱拉杆体生产时出现杆部筋板折叠缺陷的现象,通过对轴箱拉杆体工艺进行有限元分析,模拟其锻造成型过程,分析杆部筋板折叠缺陷产生的原因,通过改进制坯工艺,再次进行模拟,消除了折叠现象,经过工艺试验和实际生产,验证了模拟结果的准确性,达到了节省试验成本、提高生产效率的目的。Folding defect of the rod rib was appeared in the production of axle box rod.Through the finite element analysis of the process of axle box pull rod body,the forging forming process was simulated,and the cause of rib plate folding defect was analyzed.After improving the blank process,the simulation was carried out again until the folding was eliminated,and the accuracy of the simulation results was verified through the process test and actual production.
