| 摘要通过对力达公司从英国公司引进的二辊矫直机的消化吸收，研究分析，进行反求工程设计，成功改进设计。本论文全面地研究了二辊矫直机，分析了二辊矫直机的原理，辊型曲线，辊型特点等方面。利用数控机床点测，找出了辊型曲线，从而为辊型曲面的加工提供准确可靠的参考依据。定性分析了辊形曲线、矫直的原理，有利于进一步的改进和提高。 对整个传动系统、机架结构，工作部分，进系统分析、验证。将系统中的电机、减速机、联轴器、轴承等全部按照国家标准，实现了全部国产化。根据现场实际情况设计改进了部分结构形式，使其更加简单方便、实用可靠，有利于文护检修和操作等。对两辊矫直机中的辊身、辊轴、机架、轴承等重点关键部位进行了强度、刚度和寿命等方面的力学分析和计算，按照我国的标准进行改进设计，成功地改进了二辊矫直机。21302 毕业论文关键词：二辊矫直机，数控机床点测，改进设计，辊型曲线，力学分析 ABSTRACT Through the introduction of the British company two roll straighter digestion absorption in the Shanghai lida heavy industry manufacture Co., the research analysis, reverse engineering design, successful improvement design. This paper has the comprehensive research on the two roll straighter, analyzed the principle of two roll straightening machine, roller type curve, roller type characteristics, etc. By using nc machine tool measuring point, find out the roller type curve, thus for roller type of surface processing to provide accurate and reliable reference. The qualitative analysis of the roller shape curve, straightening principle, be helpful for further improvement. To the transmission system and frame structure, working part, analysis and verification of surveying and mapping. The system of motor, deceleration machine, coupling, bearing etc all according to the national standard, realized the full localization. According to the actual situation of improving the design of structure form, make it more simple, practical and reliable, which is beneficial to the maintenance and operation, etc. Two roller to roll body of the straightener, the roller, frame, bearing key parts of the strength, stiffness and life on the mechanical analysis and calculation, according to our country of the standard of design improvement, succeeded in improving two roll straightening machine. Keywords: two roll straightening machine, CNC machine tool measuring point, design improvement, roller type curve, mechanics analysis 毕业论文目录 中文摘要 ABSTRACT 1 绪论 1 1.1课题概述与设计意义 1 1.2国内外矫直机发展状况 2 1.3矫直机的分类 3 2 二辊矫直机的原理与作用 4 2.1二辊矫直机的原理 4 2.2二辊矫直机的作用 7 2.2.1二辊矫直机的优缺点 8 3 二辊矫直机的分析 8 3.1二辊矫直的初步分析 9 3.1.1二辊矫直机的结构示意图与技术参数 9 3.2二辊矫直机辊轴分析 11 3.2.1矫直辊受力分析与校核 11 3.2.2矫直辊轴承分析 14 3.3矫直辊的调节机构 16 3.3.1径向调节机构 16 3.3.2角度调节机构 17 3.3.3角度调节机构的设计改进 17 4 二辊矫直机辊型曲线测定与反求 18 4.1辊型曲线测定方案 18 (责任编辑：qin) |
