Abstract

687,457. Making cupped articles. MAY, O. H. June 28, 1951 [June 28, 1950], No. 15406/51. Classes 83 (ii) and 83 (iv). Forging; stamping.-A method of making a cupped shell with a minimum of waste comprises cutting out a polygonal blank preferably of three, four or six sides, shaping it to form another polygonal blank having twice the number of sides and then drawing it into a cupped shell. In the form shown, a square blank 1 is cut from a strip and held on a bottom plate by a punch 6 while it is pressed at each corner, as in Fig. 2, by jaws 3 to form an octagon. Each of the jaws 3 is actuated by a toggle 4 and operating link 5. The octagonal blank is next cupped by being forced into a drawing die 8 by a mandrel 9. The bottom of the shell is then supported by a pad 10 while still within the die and the upper edge is flattened by an annular punch 12 which descends between the die and mandrel.
