以AZ80镁合金轮毂的反挤压成形工艺为例,利用Deform有限元模拟软件,分别研究了不同压机速率、不同温度对AZ80镁合金反挤压高度的影响.通过对相同压机载荷下的不同反挤压高度的分析,得到了其在成形轮毂时的最佳压机速率为0.01~0.10mm/s和成形温度段380~400℃,为后期AZ80镁合金的热成形性研究提供了一定的理论依据.
以AZ80鎂閤金輪轂的反擠壓成形工藝為例,利用Deform有限元模擬軟件,分彆研究瞭不同壓機速率、不同溫度對AZ80鎂閤金反擠壓高度的影響.通過對相同壓機載荷下的不同反擠壓高度的分析,得到瞭其在成形輪轂時的最佳壓機速率為0.01~0.10mm/s和成形溫度段380~400℃,為後期AZ80鎂閤金的熱成形性研究提供瞭一定的理論依據.

The anti-extrusion forming process of AZ80 magnesium alloy wheels was taken as an example to study the influence of press rates and temperature on the anti-extrusion height of AZ80 magnesium alloy based on software Deform. The different height values of anti-extrusion at the same load were researched. When the best velocity is 0.01~0.1 mm/s and forming temperature is 380~400℃, the formed wheels could be obtained. The results are significant for the hot forming study of AZ80 magnesium alloy.
