冷弯成型力研究

On Cold Bend Forming Force

在研究冷弯变形过渡区基础上，按照成型过程中成型辊施加于坯料上的力所做的功与坯料在该道次中实现规定的几何形状产生变形所消耗的功相等的原理，建立了计算冷弯成型力的理论表达式．通过现场实测证实了理论计算结果与实测数据吻合良好。

According to the mechanism of equivalent function between imposed on the slab by the force of shaping roll and needed to get the desired shape in this step,a theoretical expression for calculating cold bend forming force is presented on the basis of previous work. It is also proved that the error of calculated and experimental results is less than 30%.
