转向器是汽车主要的保安总成。转向摇臂轴(图1)是转向器中的关键零件,其工作时承受很大的弯曲和扭转复合动载荷。一、工艺概况 1.工艺特点与工步设计转向摇臂轴形状复杂,金属体积分配系旋转非对称特殊结构。工艺性差,成形难度大。根据锻件形状及尺寸分析,最佳方案是利用水平分模平锻机夹紧滑块作为模锻弯曲变形机构 The steering gear is the car’s main security assembly. Steering rocker shaft (Figure 1) is a key part of the steering gear, which work under great bending and torsion composite dynamic load. First, the process overview 1. Process characteristics and step design Steering rocker shaft shape complex, metal volume distribution is asymmetric rotation of the special structure. Poor technology, forming difficult. According to forgings shape and size analysis, the best solution is to use horizontal split-platen forging machine clamping slider as a forging bending deformation mechanism
