六辊管材矫直机设计
摘要
管棒材矫直机是用于消除圆截面轧材的弯曲变形、椭圆变形以及其他类型的复杂变形的机器,目前使用的矫直机主要有二辊、五辊、六辊、和七辊矫直机等。
本设计的主要内容包括介绍了无缝钢管的发展状况、无缝钢管的生产流程、管棒材矫直机的概述、管棒材矫直机矫直理论技术的发展、矫直原理以及矫直工艺等理论,确定了矫直机的总体方案。在力能计算部分完成了管材弯矩、管材变形能、管材接触线长度、矫直力、矫直机驱动功率等计算,此外万向接轴及矫直辊传动轴等主要部件进行了强度校核,并对角度调整机构的传动装置进行了分析,对其进行了结构设计。
关键词:矫直机、矫直辊、强度校核
The design of six roller pipe straightening machine
Abstract
The function of tube-bars straightening machine is readucing bending deform ,ovaling deform and plex deform of tube present ,there are 2、5、6 and 7-rolls straightening machine
The main contents of this manual introduced the development of seamless steel pipe,the production process of seamless steel pipe, straightening machine tube development, Straightening principle and Straightening process theories, to determine the overall program of straightening machine. In calculation of force and energy parameters,it has calculated the moment of pipe,the deformation energy of pipe,the length of contact line of pipe,straightening force and the drive power of straightening addition,check the instensity of universal coupling of straightening roll and so on,and The ponents of Straightening roller and Shaft are the same time,it analysises and designs the driving device of angnlar adiustable mechanism.
Key words: straightening machine; straightening roll;Strength Check
