液压式222型钢管矫直机设计

摘  要
液压式222型钢管矫直机是无缝钢管生产车间的重要设备。其矫直辊的性能对矫直精度有较大影响，因此矫直辊的强度是一个很重要的因素。
本文在弹性理论的基础上，分析和研究了六辊管材矫直机的矫直原理，并着重对六辊矫直机的力能参数进行了理论研究。在理论研究的基础上利用三维软件建模，进一步弄清矫直辊的外形特征。通过ANSYS软件对矫直机矫直辊进行受力分析，并通过图形显示出矫直辊在各个方向上的力能参数变化情况。并列出矫直辊的总体变形图、各方向节点的变形（位移）图、单元应力云图等图像，直观有效的说明了矫直辊在工作过程中的应力变化关系。最后将有限元分析结果与理论计算值进行对比，并分析理论计算结果与ANSYS分析结果的差异和产生误差的原因。
通过以上的理论研究对正确的设计和使用六辊矫直机，深入研究矫直理论及矫直机械参数的精确度的确定具有一定的借鉴和参考价值。

Abstract
   The 222 Hydralic Pressure Roller straightener is an important equipment of seamless tube production workshop, and the performance of straightening roller have great influence on the straightening accuracy, so the strengthening roller is one of the important factors.
   In this paper, base on elastic thery analysis and research the straightening principle for six roller PVC straightener, and accent on the straightener roller’s force parimentes to process a theoretical research of six roller straightener .Based on the theoretical research and use of 3D software modeling, to make a further certain of the straightening roller,s shape characteristics. For the force analysis of the shrenghtening roller of straightener though the ANSYS software, and though the graphic to show force power parameter change for every direction of straightening roller, and list the overall deformation diagram, X direction node deformation (displacement) figure, X direction unit stress cloud graphic , X direction line graphic chart of straightening roller, to make an intuitive effectively introduction of its stress-strain relationship in working process at last compared a result of finite-element analysis with theoretical calculation, and analysis the causes of theoretical calculation result and ANSYS analysis results which throw off the error.
   Through the theory research of correct design and use of six roller straightener above,we can find that to make a deep research of straightening theory and accurately determine of straightening mechanical parameters has certain reference value.
Key words: six roller straightener; straightening roller; straightening force; ANSYS finite-element analysis
