基于DEFORM-3D的汽车转向器输入轴锻造成形研究

Research on Forging Process for Automotive Steering Input Shaft Based on DEFORM-3D

根据汽车转向器输入轴的形状,进行工艺性分析,指出零件加工的难点部位,并进行锻造工艺性分析,以取代现在的机械切削加工工艺,降低生产成本。本着简单实用的原则,制定了冷成形和冷热结合成形两套工艺方案,并通过Deform-3D对两种锻造工艺方案进行模拟分析,最终从坯料充满程度和成形力大小两方面,选定冷热结合的锻造成形工艺方案,并根据选定成形方案对输入轴进行实际锻造试验,成功锻制出合格锻件,为输入轴的工业生产提供了一套新的生产工艺。

Based on the shape of automotive steering input shaft,by analyzing process,the difficulty site of machining parts was pointed out,and the forging process was analyzed to replace the mechanical cutting process,reduce production costs.In line with the simple and practical principle,two schemes,a cold forming process and a combination of cold hot forming process,were developed;and through the Deform-3D,the two forging processes were simulated and analyzed;finally,from two aspects,the filling state of billet and the size of forming force,the combination scheme of cold hot forging technology was selected;and based on the selected scheme,the input shaft forgings were successfully formed.successfully forging a qualified input shaft forgings.So a new production process is obtained for the industrial production of the input shafts.
