摘要/Abstract

摘要： 为了提高传热效率对微犁／拉削柱面三维微翅结构进行了研究着重分析了三维几何结构参数的优化设计及翅片加工成形过程讨论了加工过程中的轴向拉力和周向推力分析了微犁／拉削方法产生的翻边毛刺的形成机理并通过试验确定了三角形拉削刀具的前角 γ 0 、刀尖角β及拉削深度α p 对毛刺的影响规律．

关键词: 三维翅片, 翻边毛刺, 微犁, 拉削, 三角形刀具

Abstract: To improve the heat transfer efficiencythe structure of the cylindrical three-dimension fin machined by mi -cro-ploughing／broaching was studiedputting a special emphasis on the optimization design of the three-dimension geo-metrical structure parametersthe formation process of the finthe axial tensile force and circumferential stress in the ma-chining processas well as the formation mechanism of flanging burrs in the application of micro-ploughing／broaching method．The effects of the rake angle γ 0 the tool angle βand the broaching deepness α p on the burrs were also investi -gated by experiments．

Key words: three-dimension fin, flanging burr, micro-ploughing, broaching, triangle tool
