环件冷辗扩中单辊随动导向运动规律研究

根据立式单导向辊随动导向冷辗环机的实际工况，建立了矩形截面环件和深沟球截面环件冷辗扩的运动学模型，分析两种环件的直径变化规律，研究了一定辗扩工艺条件下导向辊的运动规律。建立根据冷辗扩工艺来确定导向辊运动的一整套设计方法，并用MATLAB编写求解程序以求解所有的设计参数。精确地控制导向辊的运动规律有利于提高环件冷辗扩的精度。研究结果为冷辗环机的设计制造提供了依据。

Research on the Following Motion Rule of Single Guide Roller in Cold Ring Rolling

According to the actual working conditions of the vertical cold ring rolling machine with single following guide roller, the kinematical models of cold rolling rectangular cross-section ring and ball ring were established respectively, the diameter variation rules of both rings were analyzed and the guide roller motion rule under certain rolling condition was researched. A systematical design method of the guide roller motion was developed according to the ring rolling process, and a MATLAB program was programmed to solve the design parameters. Accurate control of the guide roller motion has great benefit to the precision of cold rolling ring. The research can be used as a guideline for design and manufacturing of cold ring rolling machine.
