Abstract: 667,718. Making cupped articles. BIGINELLI, O. F. A. Jan. 26, 1950 [Dec. 23, 1949], No. 2106/50. Classes 83 (ii) and 83 (iv). Extruding; forging.-In a method of making a tubular metal body from a solid blank by first pressing the blank to form a cup-shaped member which is then elongated by extrusion, the two operations are carried out in the same hollow die but by different pressing actions exerted on the blank. The apparatus comprises a bed 54 to which is screwed a cylindrical member 13 formed with a shoulder 15 which acts as a ram and an end 16 which acts as a mandrel during the extruding operation. Slidably mounted on the member 13 is a block 18 into which is screwed a container 17 with a larger bore 22 of a size to take the shoulder 15 and a smaller bore 23. An electric heater 24 may be arranged around the container. Below the bore 23 is a ram 28 with an axial opening cut away at one side so as to receive either a plunger 25 adapted to enter the bore 23 or a work-receiving device 31. Initially the space between the bed 54 and block 18 is filled by a horse-shoe shaped insert 33 and a billet is placed on the end of the plunger 25 which is raised to forge the billet to the shape shown in Fig. 12. The ram 28 is then withdrawn and the plunger 25 replaced by the device 31 which comprises internal sloping surfaces 37 against which bear elements 38 which tend to move upwards and inwards under the action of springs 40, Fig. 13A. The insert 33 is removed and the ram 28 again raised so as to contact the container 17 and force it upwardly so that the shoulder 15 acts as an extrusion ram to extrude the billet as shown in Fig. 14, the end of the extruded container entering between the elements 38 and being retained by the edges 39 thereof. As the ram is lowered, the extruded container is withdrawn from the bore 23. The bottom of the extruded container may be embossed or otherwise shaped either internally or externally by providing suitable forms on the lower end 16 of the member 13 or on the upper end of the plunger 25.
