摘　　要：　介绍了在机械压力机上温拉深过程中产生起皱的原因,通过采取调整镁合金板温度、相对厚度t/d0以及润滑剂的使用等措施,解决了拉裂、起皱缺陷,成功地拉深出镁合金盒形件产品。In this paper, the generations of wrinkles during warm deep drawing on mechanical pressing machine are analyzed. After adjusting the temperatures and relative thickness of t/d_0 of magnesium sheets, using lubricants and adopting other measures the defects including cracks and wrinkles are avoided, and box-shaped magnesium products are deep drawn perfectly.
