It is showed that the limit drawingheight could be greatly improved as a variable BHF deep-drawing process was adapted.
结果表明，变压边力拉深工艺能够极大提高板料的极限拉深高度。

The results indicated the arrayed rule, density and diameter of the drawing holes affect the limit drawingheight of sheet metal drastically.
分析结果表明，拉深孔排列规律、密度和孔径变化对板料的极限拉深高度有很大影响。
