摘要: 對理想彈塑性金屬帶材在第1個彎曲輥上的拉伸彎曲過程進行了詳細的分析,給出了不同應力分布形式的邊界條件、帶材產生塑性延伸的條件、帶材塑性延伸率的計算公式,從而確定了帶材延伸率與帶材張力和帶材彎曲曲率之間的關系.

Abstract: The tension leveling process of the elastic-perfect plastic metal strip on the first bending roll is investigated. The conditions to form different patterns of stress distribution, the conditions to allow the metal strip Undergo plastic elongation, the calculation formula of the plastic elongation and the relationship among the elongation, tension and bending curvature or radius are discussed and clearly expressed.
