查询词典 Punch

The draw ratio is the direct relationship between the draw punch and the blank edge—the greater the distance between the draw punch and the blank edge, the greater the resistance to flow, primarily because of the additional surface area of sheet metal clamped between the die face and the blank holder.

拉伸率直接体现在拉伸冲头和展开平板边缘之间的关系---拉伸冲头和展开平板边缘之间的距离越大，限制流动的阻力越大，主要是因为在压边圈和模具表面间有额外金属板表面被夹紧。试着用不同尺寸和外形的展开平板进行实验。
