摘要: 将板材在辊式矫直机矫直辊作用下的弯曲,假设为由压下机构作用的弯曲和由弯辊机构作用的弯曲共同作用的结果·根据梁的弹塑性弯曲理论,通过把板材弯曲当作梁的弯曲,并考虑到矫直机在入口处的压弯量,通常使板材弯曲时塑性变形层高度占厚度80%,认为经弯辊作用后塑性变形层高度增加了5%~15%,利用梁的弯曲挠度,建立不同弯曲的弯辊模型,求出了矫直辊的弯辊量·理论计算的弯辊量与实际设定值结果吻合,证明该弯辊量设定模型具有实际应用价值·

Abstract: On a roller leveler the deflection of a plate under the action of levelling rollers is assumed that the deflection is resulting from the forces exerted by both screw-down and bending roller. Based on the elastoplasticity theory of a beam, the bent plate is referred to as a bent beam with the entry intermesh also considered and, generally, about 80% of plate thickness is of plastically deformed layer and 5%-15% or the rest is regarded as due to the effect of bending roller. Different roller bending models are thus developed on beam deflection basis to solve quantitatively the bending of levelling rollers. The roller's bending calculated theoretically conforms with the set value, which reveals the practicality of those models.
