纵梁成形模冲压技术

Punching technology of carling forming die

论述了U形纵梁、变截面纵梁冲压变形的机理 ,对纵梁冲压变形的原因及回弹趋势进行了归类分析 。

This paper introduces the mechanism of the punching deformation of U\|shaped and variable section carlings, classifies and analyses the punching deformation reasons and trends of carlings. Accordingly it puts forward a series of the structure designs and measures for decreasing rebound of carling forming die.
