本文在应用Stone弹性基础梁假定的同时,将工作辊与支持棍视作一迭合梁,考虑了支持辊的弯曲变形和剪切变形;用幂级数t=sum from i=1 to n k_i x~(i-1)来表示工作辊与支持辊间单位长度上的接触压力,在将轧辊辊身长度进行有限等分的前提下,利用工作辊与支持辊在稳定轧制时变形的协调性,应用电子计算机技术探讨工作辊与支持辊间接触压力的分布规律和加弯辊力后的变化规律。在此基础上,推导出四辊冷轧机的板型方程,建立满足板型良好条件的,在电子计算机上计算最佳弯辊力的计算模型。并用洛阳铜加工厂六号轧机的一组实验数据与本文所推导的理论结果进行了对比分析。
In this paper, while applying the assumption of Stone elastic foundation beam, considering the work roll and the support stick as a composite beam, the bending deformation and shear deformation of the support roll are considered. Using power series t = sum from i = 1 to n k_i x ~ (i-1) is the contact pressure per unit length between the work roll and the backup roll, and the work roll and the backup roll are deformed by the stable rolling under the premise of limited division of the roll roll length The distribution rule of the contact pressure between the work roll and the backup roll and the change rule after the bending force are discussed by computer technology. On this basis, the plate type equation of the four-high cold rolling mill is deduced, and the calculation model of calculating the optimum bending force on the computer is established to meet the good conditions of plate type. A set of experimental data of No. 6 rolling mill of Luoyang Copper Processing Factory was compared with the theoretical results derived from this paper.
