摘要：

为了提高铝合金薄壁件的制造精度，对铝合金大型薄壁异型曲面旋压件的淬火变形规律进行了研究。基于ABAQUS软件平台建立了构件淬火过程有限元模型，获得了其淬火变形特征，以及固溶温度、淬火介质温度、淬火浸液方向和浸液速度对构件淬火变形的影响。结果表明：淬火后，构件将发生整体收缩或膨胀变形，且大端面呈周期性的波浪形翘曲特征；降低淬火固溶温度和提高淬火浸液速度可以显著减小构件的淬火变形；淬火介质温度将改变构件的淬火变形方式和最大变形位置，最后,确定了较小淬火变形下适合于封头构件的淬火介质温度为40 ℃；相比开口向上的淬火浸液方向，当采用开口向下的淬火浸液方向进行淬火时，封头构件大端面的淬火变形程度明显减小。

In order to improve the manufacturing precision of aluminum alloy thin-walled parts, the quenching deformation laws of large thin-wall special-shaped spinning parts with curved surface for aluminum alloy were studied. Based on the ABAQUS software platform, a finite element model of the quenching process was established, and the quenching deformation characteristics were obtained, as well as the effects of solution temperature, quenchant temperature, immersion direction and immersion speed of quenching on the quenching deformation for components. The results show that the component will shrink or expand as a whole after quenching, and the big end surface presents the periodic wave-shape warping characteristics. The quenching deformation of components can be significantly reduced by decreasing the solid solution temperature and increasing the immersion speed of quenching. The quenching deformation mode and the maximum deformation position of components are changed by the quenchant temperature. Finally, the quenchant temperature suitable for head component with smaller quenching deformation is 40 ℃. Compared with the immersion direction of quenching with opening upward, the quenching deformation of the big end surface for head component obviously decreases when the quenching immersed direction of opening downward is applied.
