转向拉杆球头销一次冷挤成型

Formation of Steering Tie Rod Ball Studs by single cold Extrusion

阐述了CA141载货汽车转向拉杆环头销挤压工艺与模具结构。这种球头销采用一冷挤成型工艺，上模采用浮动式的套料结构，增加了毛坯在模具型腔中的稳定状态，得到了上球头与林部的最佳同轴度，解决了现生产中的偏头问题，伺时减少了工序，节约了材料，提高了刀具耐用度和产品质量。

The cold extruseon process and construction of dies for steering tie rod ball studs of model CA141 truck are presented in this paper，A single extrusion forming process is adopted for manufacturing ball studs,its upper extrusion die features a floatable cover type,and ball stud blanks are therefore able to be steady in mner diecavity,consequently the coaxality between upper ball stud and stem can be ensured,and the problem of off set of the bal1 stud existing production can be solved as well. In addition,the new process can cancel some manufacturing operations,save material,improve tooling endurance and guality of products.
