Abstract

284,545. Gauld, D. M. July 11, 1927. Cupped articles.-In making rings for roller bearings of comparatively thick plate the latter is cupped in known, manner, and the cup is then heated and turned inside out. In the reversing operation the cup E is inverted upon a die DY and pressed by a ram C, Fig. 6, into a flanged closed-ended cone F. The cone is then placed in the position shown dotted in Fig. 7, and the flange FY is engaged by a surface CY on a ram C' and the conical tube is forced into a die D to form a cylindrical tube. The surface CY holds the flange in a recess in the top of the die to jump the metal at the point HX. Ejectors G expel the tubes. In forming tubes of small size the cup is reversed into a cylindrical form. The tubes may be of any cross-sectional shape and with parallel, stepped, or conical sides.
