Abstract
1,250,413. Making bolts; rolling screw threads. REED ROLLED THREAD DIE CO. 30 Jan., 1969 [31 Jan., 1968; 3 May, 1968], No. 5218/69. Headings B3A and B3M. [Also in Division F2] A self-locking screw (see Heading F2H) is made by rolling a cylindrical workpiece between thread forming dies to form a thread on the workpiece and deforming a flank of at least a part of at least one turn of the thread between the crest and root thereof to form an arcuate rib 62 of substantially triangular cross-section parallel to the crest and diverging outwardly beyond the flank leaving a cavity 70 of corresponding shape and volume to the rib. The tool 58 used to form the rib is preferably incorporated into the discharge end of one of the dies used to form the thread, Fig. 5. The other die has an unthreaded portion 82, Fig. 6, for producing ribs of more than 180 degrees of a thread so that the rib is not wiped out by the further action of the other die. This other die also has the threads at its discharge end relieved away from the one die so that the leading edge of a rib is first engaged by an unrelieved wall of a thread in the other die to bend it back into the flank of the screw thread and then as thread rolling continues the screw is moved away from said one die causing the trailing end of the rib to be made shallower and taper back into the flank of the screw thread, Figs. 19 to 25 (not shown).
