Abstract

862,518. Extruding; forging. TEXTRON Inc. Aug. 7, 1959 [Sept. 4, 1958], No. 27050/59. Class 83 (4). A cup-shaped metal body 46 is made by cutting a workpiece from substantially circular stock 13 upsetting the workpiece in a die 15, station 1, and simultaneously chamfering one end 17 whilst indenting the other end 20, further upsetting it in another die 33, station 3, whilst flattening the chamfer and deepening the indent 36, and backwardly extruding it in a further die 41, station 4, by a punch 44. Additional upsetting and sizing may be performed at station 2. The blank is cut off and transferred to station 1 by a knife 14. Punches 19, 28, 35, 44 are carried by a reciprocating gate 11. Ejector punches 18, 27, 34, 43 are provided and a stripper for station 4 may also be fitted.
