【摘要】 探索了在普通车床上加工三维外翅片管的新方法，开发出了一种A型三维外翅片管。试验结果及理论分析表明，A型三维外翅片的形成要经过滚压和挤压-犁切两个步骤。外翅片的形成包括挤起、切开及成翅三个阶段。翅片形状主要取决于挤压-犁切用量及刀具几何参数。更多还原

【Abstract】 A new method of machining 3D fin tube on the turning machine is presented, and investigated a 3D A-finned tube. The experimental and theoretical results show that the formation of 3D A-finned tube includestwo steps, namely rolling and extrusion-ploughing. The outside fin formation consists of bulging, cutting andextruding. The appearance of the outside fin mainly depends on the feed and depth of extrusion-ploughingand the tool geometric.更多还原
