| abstract | 806,071. Making nuts and the like. HOLOKROME SCREW CORPORATION. May 28, 1956 [Aug. 29, 1955], No. 16387/56. Class 83 (4). Forging; shearing; working at specified temperatures.-An apertured article, particularly a nut blank or a ball-bearing race, is made by forging a steel or other forgeable ferrous metal slug heated to a temperature above 150‹ F. and not allowing the temperature to exceed 650‹ F. during forging. In the manufacture of hexagon nut blanks, steel stock 10 coated with a lubricant such as aluminium stearate or molybdenum disulphide suspended in oil, is fed through a water-cooled induction heater 12 operating at a frequency of 500,000 to 2,000,000 c.p.s., and heated to about 250‹ F. Slugs are then severed from the stock by a knife 14 and fed successively through punch and die sets 16-24 where they are formed in steps, Figs. 3-7 (not shown), into nut blanks. The blanks are turned end for end by the transfer mechanism between successive forging stations except between 22 and 24. At the last station, a wad of metal, Fig. 7c (not shown), is punched out of the blank. The apertured blank may alternatively be formed in two successive operations in the same or different dies. The temperature of the slugs is prevented from exceeding 650‹ F., preferably 600‹ F., for example, by regulating the speed of forging. |
