摘要：

对于汽车上的循环球式转向器转向螺母等复杂构件，其传统的制造工艺存在材料利用率低、生产周期长、生产成本高及产品综合力学性能低等问题。针对以上问题，提出转向螺母多轴联动成形工艺，利用有限元模拟软件Deform-3D对转向螺母多轴联动成形工艺进行了模拟仿真，得到了主要运动模具的载荷及模具应力场分布。然后根据模拟结果设计了实现该工艺的多轴联动成形压机结构，利用ANSYS Workbench有限元分析软件对多轴联动压机机身进行了模态分析，最后根据多轴联动成形工艺顺序设计了多轴联动压机液压控制系统和电气控制系统。该多轴联动压机不仅能为汽车复杂构件的实际生产提供指导，还能应用于其他复杂构件的多轴联动成形。

For complex components such as the steering nut of recirculating ball steering gear in automobiles, the traditional manufacturing process has problems such as low material utilization, long production cycle, high production cost and low comprehensive mechanical properties of product. Therefore, in response to the above issues, a multi-axis linkage forming process for steering nuts was proposed, which was simulated by finite element simulation software Deform-3D, and the load of main moving molds and the stress field distribution of molds were obtained. Then, based on the simulation results, a multi-axis linkage forming press structure was designed, and the modal analysis of the multi-axis linkage press body was carried out by finite element analysis software ANSYS Workbench. Finally, the hydraulic control system and electrical control system of the multi-axis linkage press were designed according to the sequence of the multi-axis linkage forming process. Thus, this multi-axis linkage press not only provides guidance for the actual production of complex automotive components, but also can be applied to the multi-axis linkage forming of other complex components.
