摘　　要：介绍了对开式中厚板矫直机弯辊装置的结构特性,确定了各部件之间的力作用关系和运动关系,建立了弯辊装置整体力学模型和偏心轴与左右压力框架在负弯和正弯时单体力学模型,并对弯辊装置在工作辊负弯和正弯时进行了力学分析,根据工作辊的极限转角和极限弯矩,求解出负弯和正弯时弯辊装置的弯辊矩和弯辊液压缸需要输出的最大作用力,为弯辊装置的结构设计及其强度、刚度校核提供了理论依据,为其尺寸优化提供参数上的依据。This paper introduces the structural characteristics of the bending roll decice,ascertains the relationship between force and motion relationship between the various components,builds a mechanical model of the whole bending roll device and a single mechanical model which is between the eccentic shaft and the farme on a status of negative bending pressure and positive bending pressure,makes the mechanical analysis for bending roll device. According to the limit angle and bending moment of the working roll to get the maximum bending force and maximum hydraullic cylinder output. Through study provides a theoretical basis for the structural design,strength checking of bending roll,and provides a parameter basis for the size optimization.
