针对现有某轻卡转向节成形过程中出现的缺陷,结合实际生产提出了辊锻制坯成型与模锻相结合的锻造成型工艺。同时,利用Deform软件建立有限元数值模拟对成型过程进行了分析。结果表明,通过优化辊锻制坯相关参数,可以解决杆部和叉形顶部出现的充填不满的问题。对数值模拟仿真结果进行的生产验证表明该方法是有效的。 Aiming at the defects in the existing forming process of a light truck knuckle, a forging process combining with roll forging and die forging is proposed in combination with actual production. Meanwhile, Deform software was used to establish finite element numerical simulation of the forming process. The results show that by optimizing the parameters related to roll forging billets, the problem of underfilling in the stem and fork tops can be solved. The production verification of numerical simulation results shows that this method is effective.
