以2A12硬铝电动机支架为对象,通过数值模拟的手段研究了复合挤压一次成形工艺。结果表明,复合挤压一次成形效果良好,充填饱满,成形过程中2A12硬铝没有发生破裂。
Taking 2A12 hard-aluminum motor bracket as object, the compound extrusion forming process was studied by means of numerical simulation. The results show that the composite extrusion has a good forming effect and full filling, and the 2A12 ductile aluminum does not rupture during forming.
