Utilized the correlative knowledge of mathematics and theoretical mechanics, the movement measure of the rolling forming of rectangle ring have been studied that based on the ring rolling theory. And the corresponding geometrical models and mathematical models have been established. It was revealed the variation law of ring in the cold rolling process.With the rolling processing, the inside and outside diameters of ring gradually increased with the cures similarly hyperbolic and the augment speed of the inside diameter was obviously larger than the augment speed of the outside diameter. With the rolling processing, the displacement, speed and acceleration of the ring centre gradually increased in the feeding direction in the horizontal and vertical ring rolling mill. With the rolling processing, the moment of inertia which ring reeled its centre and the whirligig of ring gradually increased. It caused the rotary speed gradually decreased. And it was benefit to decrease the circle tolerance and improve the precision of final molding.

本文基于环件轧制理论，运用相关的数学知识和理论力学知识，研究了冷轧过程中矩形截面环件轧制成形的运动测量，并建立相关的几何模型和数学模型，揭示了冷轧过程中环件的变化规律：随着轧制过程的进行，环件的内外径随类似于双曲线的曲线逐渐增大，且环件内径增大速度大于外径增大速度；在卧式轧环机和立式轧环机下，随着轧制过程的进行，环件中心的位移、速度及加速度不断增大；随着轧制过程的进行，环件绕其中心的转动惯量不断增大，导致环件的转速不断减小，这样有利于环件的整圆和最终成形环件的精度。

Selecting corresponding rolling force model, the paper make an experiment and studies on cold rolled paper-thin strip processing characteristics of sixteen-roll rolling machine based on cold-rolled theory aand forms corresponding rolling model, tension model and moment calculation model .And comes to a conclusion that distortion force and press utmost have a large effect on rolling force and paper-thin strip shape, primarily presenting paper-thin strip rolling subarea theory that rolling force decreases corresponding to the thick decrease of strip but increases rapidly when to a certain thick.

结合带钢冷轧基本理论，选用适当的轧制压力模型，针对十六辊轧机轧制极薄带钢时的工艺特点进行了实验和分析，建立了相应的张力模型及辊系传动力矩模型；并得出变形抗力及压靠对轧制极薄带钢时的轧制力和板形有很大的影响，初步提出了当带厚较大时，为保持板形良好，随着轧件厚度的减少，轧制压力相应降低，当轧制到一定厚度时，轧制压力随着带厚的减少急剧增加的极薄带轧制分区理论。

In view of product quality of cross wedge rolling semifinished product of automotive power-shift box middle shaft which has heavy sectional shrinkage, numerical simulation and experimental method were adopted to analyze single wedge rolling and second wedge rolling method. It is found out that contrast second wedge rolling, single wedge rolling will not make workpiece bend easily, and after rolling the workpiece has no neck shrinkage.

针对用楔横轧工艺生产具有大断面收缩率特点的汽车变速箱中间轴毛坯所存在的产品质量问题，利用数值模拟与实轧试验对汽车变速箱中间轴毛坯一次楔成形和二次楔成形进行了分析研究，发现采用一次楔成形方法加工汽车变速箱中间轴毛坯，轧件不易发生弯曲，中间断面收缩率最大处没有发生缩颈现象，心部质量也较二次楔成形好。
