摘要对于材料厚度较大的金属，若想要通过卷制得到圆形、弧形、锥形等结构，四辊卷板机是一种很适合的手段。它具有一些鲜明的特点，例如能对板材端部进行预弯，避免焊接时两端不对齐；很高的工作效率，端部剩余的直边很少；通过自身作用可对板料进行大概的校正，这是三辊、二辊无法比拟的。本次毕业设计研究或解决的问题是，通过了解四辊卷板机国内外的研究现状，设计计算机械结构并对关键部件性能分析来加工尺寸厚度60mm，长度2000mm的板材。26257
本论文的撰写通过四步来完成，首先，在了解了目前国内外卷板机现有的结构、原理基础上，进行了归纳、分析，撰写出文献综述；然后，在研究现有卷板机机械结构的基础上，确定了四辊卷板机优化结构；通过Solidworks绘制出样机三文设计结构图与工程图；最后，应用有限元分析软件Ansys对关键部件进行了性能分析与强度校核，对全文进行了总结。

Title Three-dimensional design and performance analysis of four-roll bending machine
Abstract
For metals with large material thickness,if you want to get round,rolling arc,conical structure by rolling,four-roll bending machine is a great suitable means .there are some distinctive features,such as preflex at the end of sheet material to avoid the circumstance of not aligned at both ends when welding;High efficiency and less remaining part at the end of sheet material;By using its self function,to adjust the sheet material probably,it’s incomparable for two or three roller bending machine. The research and solution point of my graduation design is ,By investigate the research condition of four-roll bending machine at home and aboard, designing and calculating the mechanical structure,analysing the property of key component，to process sheet material thickness 60 mm,length 2000 mm.
This paper completed by four steps ,first of all,On the base of knowing the existing structure and theory of four-roll bending machine at home and aboard,I've summarized and analyzed it to work out literature review.secondly,On the base of now existing mechanical structure of bending machine,I've defined the structure optimization of four-roll bending machine ,so that i could draw three dimensional structure and engineering drawing of the sample by solidworks.moreover,through finite element analysis software,ansys,checked the strength and analyzed the performance of the key component,summarized my thesis.
Keywords four-roll bending machine，three-dimensional design structural optimization， performance analysis
