薄板钢材成型时,控制其口弹量是很重要的。尤其在加工几个相互配合的零件时,若不控制回弹量就会产生难以装配的后果。实践证明回弹量与钢材的特性和模具的结构有关,钢材的强度越高,弹性模量越低,且工件的弯曲半径和模具的间隙越大则成型的回弹量就越大,对某一种钢材而言,若模具 When forming sheet steel, it is important to control the amount of bounce. Especially in the processing of several parts with each other, if you do not control the amount of rebound will produce difficult to assemble the consequences. Practice has proved that the amount of rebound and the characteristics of steel and the structure of the mold, the higher the strength of the steel, the lower the elastic modulus, and the bending radius of the workpiece and the mold gap is larger the larger the amount of springback, forming a A steel, if the mold
