摘　　要：由于6082铝合金多腹板零件的强度和硬度较高且形状特殊而复杂,使得材料在凹模腹板型腔底部和中间轴下部充填较为困难。本文提出了三种冷挤压工艺方案,并通过有限元软件Deform对三种方案进行了模拟分析和优化。最终,得到的优化方案为:剪床下料,然后整形加压凹,再经过冲孔最后一次挤压成形。As the strength and hardness of 6082 aluminum alloy multi-web parts are high and the shape is special and complex,it is difficult for the material to fill the bottom of the die web cavity and the lower part of the middle shaft.Three cold extrusion process schemes were proposed and simulated and optimized by finite element software Deform.Finally,the optimized scheme is as follows:cutting the material on shearing machine,then shaping and pressing the concave,and then punching and finally extrusion forming.
