Abstract
392,301. Forging nuts. BROMLEY, T., 217, Wigan Road, Atherton, near Manchester. Feb. 13, 1932, No. 4317. [Class 83 (iv).] For a machine for making nut blanks from hot-bar, the bar is positioned against a fixed back-stop 10 and tools 26, 27 are reciprocated by cranks 21 to sever a blank and to shape the end of the bar 33. A punch 37 and an ejector punch 38 are reciprocated by a cam 45 to move the blank into an hexagonal stationary die 8 and to compress it. The punch 38 then remains stationary and the punch 37 moves to force the blank against a face 63 of a snap tool 39 to form a chamfer, and on to a punch 40 to form a hole. The wad from the hole is transferred to the interior of the punch 37. The cam 45 withdraws the punches 37, 38 and a cam 48 reciprocates the punch 39 to force the blank from the die. A cam 59 then actuates a knocking-off finger 62 which disengages the blank from the punch 39. The wad is then ejected from the punch 37 by rearward movement of the punch 37.
