摘　　要：对阀螺钉结构进行分析,结合所选用材料,提出阀螺钉冷挤压成形方案,并对其进行工艺参数的计算。运用Qform2D/3D软件对工艺方案进行数值模拟,分析阀螺钉在挤压成形中应力、应变的分布,最终确定合理的成形工艺方案。通过工艺实践验证,结果表明设计合理,可为实际生产提供指导。A process of cold extrusion for valve-boh was proposed by analyzing the structure of the valve-bolt and the selected materials. The parameters of the process were calculated too. Utilizing Qform2D/3D software , a nu- merical simulation of the cold extrusion process was made. The distribution state of load and strain of the valve- bolt in the extrusion was analyzed. Based on the analyzing of the above, a reasonable forming process scheme was determined. Through the practice verification process, the results show that the design works well. It can provides guidance for practical production.
