Abstract

622,558. Making nuts. SECURIT'S E.D.L.C. March 26, 1947, No. 8270. Convention date, April 4, 1946. [Classes 83 (ii) and 83 (iv)] Forging screw-threads; angular bending &c.- An internally-threaded split-ring with external taper and flats for a lock-nut is made by forging in dies 3, 4, a flat blank 1 to form a thread 4a on one side and flats 1b on the other. The blank is then bent to semi-circular form in dies, Fig. 3, (not shown), which complete the forming of the thread and flats, and is then bent around a screwed mandrel by vertically and horizontallyreciprocated dies. The rings may be made singly or in pairs which are subsequently split.
