摘要:

为了得到具有大直径大膨胀率且壁厚减薄小的铝合金Ω形波纹管,提出了一种轴向低压压形工艺,其核心思想是通过合理匹配成形内压与轴向进给间的关系来提高波纹管的成形质量。同时,通过实验与数值模拟分析结合的方式,基于ABAQUS有限元分析软件,建立了波纹管轴向低压压形过程的有限元模型,并基于波纹管轴向低压压形过程中的等效应力及壁厚分布情况,分析了3种不同加载路径对波纹管成形过程的影响,获得了成形内压与轴向进给间最佳的匹配关系。结果表明,由加载路径3阶梯形匹配关系所得波纹管的形状精度高,最大减薄率为12.1%,验证了工艺的可行性。

In order to obtain the aluminum alloy Ω-shaped bellows with large diameter, large expansion rate and small wall thickness thinning value, an axial low pressure forming process was proposed, and the core idea was to improve the forming quality of bellows by reasonably matching the relationship between internal pressure and axial feeding. At the same time, the finite element model of bellows in axial low pressure forming process was established by the combination of experiment and numerical simulation analysis and based on the finite element analysis software ABAQUS. And based on the equivalent stress and the wall thickness distribution in axial low pressure forming process of bellows, the influences of three different loading paths on the forming process of bellows were analyzed to obtain the optimal marching relationship between internal pressure and axial feeding. The results show that the shape accuracy of bellows obtained by the stepped matching relationship of path 3 is high, and the maximum thinning rate is 12.1%, which verifies the feasibility of process
