Abstract
124,993. Longmore, S. July 12, 1918. Tube expanders; riveting.-The expanding- rollers d are mounted in grooves in the mandrel a, and the mandrel moves outwards from the tube during the expanding process. The screwthreaded collar e is held stationary while the mandrel a is rotated to withdraw it. The collar e may be reversed so that the rollers d engage in the recesses h at the end of the expansion, and the collar may be formed with an extension passing into the tube f to form a bulged portion on the end of the tube. Fig. 6 shows a form in which ball-headed rollers d expand the tube to fill grooves in the plate g. The collar e may be provided to carry balls bearing on the end of the tube f to burr over the end of the tube. The rollers d may be placed with their axes inclined to the axis of the mandrel, and a number of balls of decreasing diameter may be used in place of the rollers.
