Patent
·
OSTI ID:4309683
A tube flaring apparatus designed to roll flawless uniform flanges on tube ends suitable for use in a Van Stone joint is described. Tapered rollers are mounted on gear segnnents and placed in the end of the tube. The assembly is rotated axially within the tube, and periodically the gear segments are moved by a worm gear so as to force the rollers radially against the tube wall until eventually a perfect 90 d flange is formed on the tube. All flanges formed by this machine are uniform, stronger, and have fewer possibilities for leaks than conventional methods heretofore used.
