Abstract

156,199. Mewes, Kotteck, & Co. Ges. Sept. 1, 1916, [Convention date]. Tube expanders.-In an apparatus for simultaneously expanding and beading tubes into flanges as described in Specification 156,198 the one-part expanding and beading rollers are replaced by two separate rollers for expanding and beading and a third roller is provided for preventing the formation of a ridge liable to be formed at the point where the other rollers meet. The apparatus is thus suitable for tubes of small diameter. In the form shown, the expanding roller f, which is cylindrical or slightly conical engages the tapered mandrel d and the beading roller c has conical surfaces c<1>, c<2> engaging the mandrel. The third roller f' is longer than the roller f so as to engage the portion of the tube unacted on by the rollers f, c. In the form of expander in which three sets of rollers are used, two sets are as shown at f, c and the third set consists of the roller f<1> cylindrical or slightly conical. In cases in which four sets are used, two opposite sets are as shown at f, c and the other two opposite sets are as shown at f<1>.
