摘要:
本文对楔形板在矫直时矫直机下辊倾斜进行了研究,分析了下辊水平与倾斜两种状态下的矫直特点,并基于线性递减矫直方式对楔形板矫直过程进行了有限元模拟,分析了楔形板在下辊水平与倾斜两种情况下的矫后残余应力。研究结果表明:在楔形板矫直过程中,根据楔形板坡度合理调整矫直机下辊倾斜角度,矫直后的楔形板残余应力越小,矫直效果越好;楔形板坡度越大,下辊倾斜状态对楔形板矫直的作用效果越明显。
Abstract:
Under rolls tilt in the process of leveling longitude profiled plate is researched in the paper.The leveling characteristics in two cases of under rolls level and under rolls tilt are analyzed.The process of leveling longitudinal profiled plate is simulated by the finite element method based on the linear decreasing leveling method.The residual stress of longitudinal profiled plate in two cases of under rolls level and under rolls tilt after leveling is analyzed.The results of research show that the tilt angle of the leveler’s under roll is adjusted reasonably according to the slope of the longitudinal profiled plate in the process of leveling longitudinal profiled plate.After leveling the longitudinal profiled plate,the residual stress of the plate decreases and the leveling effect becomes better.The larger the slope of longitudinal profiled plate is,the more obvious of the leveling effect for under roll being tilt is.
