High Speed Cold Die Forging Technology and Die Design of Automotive Epicyclic Gears

分析了汽车行星齿轮的冷模锻工艺。指出了设计冷模锻锻件图、选择毛坯尺寸及变形 速度、验算许可变形程度及进行毛坯制坯处理的要点。介绍了冷模锻模具结构及必须注意的 问题。

This paper analysed the cold die forging technology of automotive epic yclic gears. It presents the outline of designing the cold die forging drawings, selecting the blank dimension and the deformation velocity, checking the permis sible deformation degree and formulating the preparative treatments of the blank . The die structure of cold die forging was introduced.
