| 摘 要： | 设计开发了一种新型的犁切/挤压刀具,通过滚压-犁切/挤压复合成形技术,在不锈钢管外表面加工出三维整体翅片.翅片形成分为两个过程:首先滚压出V型沟槽,然后通过犁切/挤压在V型沟槽上生成三维整体翅片.实验分析了不同滚压条件下形成的沟槽形貌,以及不同犁切/挤压条件下形成的三维整体外翅片形貌；并探讨了犁切/挤压深度、进给量对翅...

| Abstract: | In this paper,a novel plowing/extrusion tool is proposed to develop a new compound forming technique of rolling-plowing/extrusion to machine outside 3-dimension integral fins on stainless steel tubes.The machining process is divided into two stages: to fabricate V-ribs by rolling and to machine 3-dimension integral fins on the V-ribs by plowing/extrusion.Moreover,the morphologies of the ribs and the fins under different processing conditions were experimentally analyzed,and the effect of the plowing/extrusi... |
