摘要：

为了提高铝合金板材轮毂的强度、刚度和外观质量，需对其轮缘进行卷边成形。轮缘部位的成形工艺因其高精度要求而变得复杂，且成形过程难于控制。通过试验研究和有限元模拟方法，对铝合金板材轮缘卷边部位的拉深缩口成形工艺进行研究。建立了3\|D弹塑性有限元模型，并给出合适的边界条件。分析了卷边轮缘成形过程中塌边、塌角和端面圆跳超差产生的原因。结果表明，通过一次拉深和30°、60°、90°的3次缩口成形，可以得到优良的卷边轮缘。

Rolled lip is needed to enhance the intensity, rigidity and aesthetic feeling of aluminium alloy plate-wheels. The forming technology is complex for the exacting requirements of rolled lip. And the forming process is difficult to control. Drawing-necking technology adopted to form rolled lip of aluminium alloy plate-wheels was researched and simulated. 3-D elastic-plastic finite element models were constructed and appropriate boundary conditions were given out. The reasons for edge collapse, conner collapse and out of tolerance of run-out in end face were analysed. The results show that rolled lip of aluminium alloy plate-wheels with good forming quality can be formed by one time drawing and 30°60°90° three times necking technology.
