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 CA141 truck steering rod ring head extrusion process and die structure are described. The ball pin with a cold extrusion process, the use of floating die on the die material structure, increasing the stability of the blank in the mold cavity, obtained on the ball and the Ministry of the best coaxial forest to solve Now the production of the migraine problem, when the server reduces the process, saving materials and improve the tool durability and product quality.
