摘要
通过对室温下AZ31B板筒形件压力润滑拉深的成形过程数值模拟分析,研究了内压力、压边力和凸模圆角半径等工艺参数对成形件壁厚差的影响。通过分析比较镁合金普通拉深和压力润滑拉深的成形效果,研究了成形件的壁厚分布情况。
The forming process of pressure-lubricating deep drawing of AZ31B magnesium alloy cup parts was simulated at room temperature. The technological parameters which influence the wall thickness difference of cup parts were investigated, including internal pressure, blank holder force and punch corner radius, etc. Compared with the forming behavior of common deep drawing and pressure-lubricating deep drawing of magnesium alloy, the wall thickness distribution of cup parts was discussed.
