中文摘要： 针对阀体零件的结构特点，分析了其挤压成形工艺，提出了一套复合挤压成形的工艺方案,并利用数值模拟软件，分析了金属成形时的流动规律，同时分析了成形时的压力行程曲线，从而保证了挤压件的质量，并以此为依据，利用SolidWorks三维软件设计了一套复合挤压模具。
英文摘要：According to the structure character of valve body, analysis of its extrusion process，and a process scheme based on compound extruding was proposed. Based on the simulation software, the flow law of metal forming and the curve of pressure-stroke were analyzed. And the quality of the extrusion was assured. The compound extruding die was designed by the three dimensional software of SolidWorks based on the result.
