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。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
