汽车球销冷镦挤成形工艺及模具

The Cold Heading and Extruding Forming Process and Mold of Automotive Ball Pin

球销是汽车转向系统中的一个关键零件，球销质量的好坏直接关系到汽车行驶的安全。因此绝大多数汽车上的球销都要求锻造面成。根据这一要求，本文叙述了汽车球削镦挤成形的成形工艺，包括工艺性分析，成形过程计算机数值模拟及工艺方案的确定。同时进行了挤压模具和冷镦挤模具设计。以提高球销的强度和寿命，降低成本。

Ball Pin is a key part of automotive steering system, and its quality is directly related to the safety of driving. Consequently ball pin of most vehicles requires forging . According to this requirement, the article narratives the cold heading and extruding forming process of automotive ball pin, including technology analysis, computer simulation of forming process and making sure the process plan. And also the article makes design for extruding mold and cold heading mold in order to enhance the strength and life of ball pin, and lower the cost.
