摘　　要：对微沟槽热管充液旋压成形工艺进行了研究,通过试验对影响充液旋压成形加工的三种关键性因素进行了研究与分析。结果表明,在影响充液旋压加工沟槽式热管的三种因素中,旋压当量直径和刀具与滚珠间相对位置主要影响热管内微沟槽形状和尺寸大小,如槽深、槽宽和深宽比;刀具与滚珠间相对位置和拉伸速度影响充液旋压加工过程中铜管是否被拉断;拉伸速度对热管表面粗糙度影响很大。A oil-filled spinning method for machining the micro-groove structures in the internal surface of copper pipe is introduced. Three key influencing factors on the formation of the micro-groove structure in the internal surface of copper pipe are analyzed via experiments. Results indicate that the equivalent diameter of the spinning balls and the relative position between the tool and spinning balls show much influences on the groove shape and dimension,such as the groove depth,the groove width and ratio of depth to Width. While the relative position between the tool and spinning balls and drawing velocity decide whether heat pipe will be dragged off, and drawing velocity greatly influences the roughness of the outer pipe surface.
