翻边的 meaning in English

turn down rims

This paper analyzes the stretching and turning edge process of big deformation for an array turning edge - hole and proposes some solutions to the problems
对固定支架成形的变薄引伸、翻边的工艺进行了分析,对出现的问题提出了解决办法。
General rules were validated and a new rule was discovered : i . e . the shape 0f these two stress fields are same , the equivalent stress of the round corner in the bottom reached its maximum at the first phase , the equivalent stress of the edge of hole reached its maximum at the third phase , the equivalent stress of flanging with cone - shaped punch descend more than that with column - shaped punch at the fourth phase i . e . the phase of deformation completed
验证了一般规律，也发现了新规律，即两者的应力场形状相同，底部圆角处等效应力在变形第1阶段最大，孔口边缘处等效应力最大出现在变形第3阶段，第4阶段（变形终了时）锥形冲头翻边的等效应力比柱形冲头翻边时下降更大。
