摘要：

采用滚压－犁切／挤压复合加工方法成形三维整体外翅片管，设计了犁切／挤压成形刀具，分析了三维整体外翅片的犁切／挤压成形过程，研究翅片顺利成翅的条件和翅片高度随工艺参数的变化规律。推导了翅片顺利成翅的临界进给量计算公式，并用实验进行了验证；在实验研究的基础上，对加工工艺参数的合理选择进行了分析。

Abstract:

Rolling and plowing/extruding method was used to machin integral serrated outside finned tube. The plowing/extruding tool was designed and the forming process of integral serrated outside fins by plowing/extruding was analyzed. The terms of fins forming and the influences of the technical parameters on fins height were investigated. The formula of critical feed was deduced and validation experiments were conducted. Moreover, how to choose technical parameters properly was analyzed by experimental results.

Key words: integral serrated outside finned tube, plowing/extruding, critical feed, fin height
