Abstract

1377046 Forging; extruding J A SIMON 27 March 1973 14761/73 Headings B3H and B3P A flared ended tubular metal body, e.g. an axle case, is made from a tubular blank 18 by extruding the blank in a die 20 using a punch 29 to form a tubular extension and an annular head and then expanding the head using a second punch 36, Fig. 6, while the extruded blank is mounted in a second die 33. The blank may be steel heated to about 1200‹ F. before each forming step and coated with a phosphate lubricant. The first punch 29 has an integral mandrel 30 to form the bore of the metal body during the extrusion. A mandrel 39 is also provided on the second punch to fit into the bore during the expanding. The expanding step causes both the outside and inside diameters of the head to increase, Fig. 7 (not shown).
