Deformation extent is described by burring factor in the process of round hole burring.

引言在圆孔翻边过程中，孔缘处受单向拉应力作用，减薄最大。

The edge metal of round hole often splits if the burring factor is less than the limiting burring factor.

当孔缘处变形程序超过极限变图 1 圆孔翻边示意图形程度时，孔缘处就会发生破裂。

In this paper, several approximate methods are put forword to calculate the limited burring factor through analyzing stress and strain at the edge of the round-hole in the burring process.

这种极限变形程度可用极限翻边系数来描述，即在翻边过程中，翻边系数(K =d0 /Dm，式中d0 、Dm 分别为板料原始孔径和翻边后竖边中径图 1)，不能小于极限翻边系数。目前，在冲压理论中，有关极限翻边系数的理论探讨还很少[1，2 ，3] 。
