摘要：

为了揭示5A06铝合金进行复合挤压成形复杂构件时的金属流动成形规律以及力学性能的变化，根据复杂构件的形状结构特点，制定了复杂构件复合挤压成形工艺方案，并增加预成形阶段，使棒料被挤压成与挤压件外轮廓基本相同。研究了5A06铝合金在复杂应力状态下的变形行为，并利用Deform-3D软件模拟复杂构件的成形过程，研究了模拟结果的行程-载荷曲线、等效应力以及金属流线分布，最终利用THP61-3 MN数控液压机进行产品试制。研究结果表明，生产试制结果与模拟结果基本吻合，且复杂构件的性能得到了明显改善，模拟分析结果为成形工艺的完善与优化提供了理论依据。

In order to reveal the forming rule of metal flow and the change of mechanical property for complex components of aluminum alloy 5A06 in compound extrusion forming process, the compound extrusion forming process scheme of complex components was designed according to the shape and structure characteristics of complex components, and the preforming stage was added to make the bar be extruded into the same outer contour as the extruded parts. Then, the deformation behavior of aluminum alloy 5A06 in the complex stress states was studied, and the forming process of complex components was simulated by Deform-3D. Furthermore, the simulation results of stroke-load curve, equivalent stress and distribution of metal flow line were researched, and the trial products were produced by THP61-3 MN numerical control hydraulic machines. The research results prove that the results of trial production and simulation are matched with each other, and the performances of complex components are significantly improved. Thus, the simulation analysis results provide a theoretical reference for the improvement and optimization of the forming process.
