中文摘要：针对壳体零件的结构特点，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DEFORM-2D，分析了金属成形时的流动规律，同时分析了成形时的最大等效应力、损伤因子和最大成形载荷，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 characteristic of shell piece, its extrusion process was analyzed, and a compound extruding process scheme was proposed. Based on the simulation software DEFORM-2D, the flow law of metal forming, maximal effective stress, damage factor and maximal forming load was analyzed. And the quality of the extrusion pieces was assured. The compound extruding die was designed by the three dimensional software SolidWorks based on the result.
