抄録

In order to prevent the phenomena of outward curling and waving in flaring of tubes, deformation behavior in rotary flaring process with off-centered tool was experimentally investigated. The influence of the off-centered distance between tool axis and tubular axis δ, the feed of tool per revolution f, tool angle, tube diameter and lubricant were studied by using aluminum and aluminum alloy tubes. It was found that, by increasing δ and decreasing f, the formation of outward curling and waving could be avoided in the flaring process. Furthermore, it was also clarified that these parameters, δ and f, were closely connected with the contact area ratio X which denotes the ratio between the contact area and the total deformed area of the tube. X was proved to be the controlling factor for the formation of outward curling and waving. Experimental results showed that X recommended for practical use should be lower than a minimum X to prevent waving.
