摘要： This invention relates to thread rolling dies for making selflocking fasteners. The self-locking result is achieved by a massive rib on the fastener which may be continuous or discontinuous in the flank or flanks of one or more turns of the threads over a selective length of the screw or internal thread. The rib is relatively massive and has an open spiral groove between it and the crest of the remainder of the thread to provide compression and resilient bending of the rib. The rib may extend out from the root of the thread as far as or slightly further than the crest of the remainder of the thread, to provide locking action under all circumstances. Further, the outermost face of the rib is provided with a bearing surface which is generally parallel to the flank of the mating threads, so that with standard threads it is disposed at approximately 60* relative to the axis of the fastener, to preclude scoring of the mating thread despite variations in fit. The screw threads and ribs theron may be made by the use of flat or circular thread rolling dies in which certain ''''threads'''' or ridges in at least one of the dies, have been reformed in a shape complementary to the rib over a suitable length in a corresponding manner. Long die life is achieved with the open groove between the rib and the crest of the remaining thread, because the die edge which forms the groove can have a greater included angle and thus have greater strength. The thread rolling die may also have the selected modified ridges extending for the entire length of the dies so that the inexpensive crush ground grinding wheel process may be used in the manufacture of the dies, with no additional manufacturing steps being required.

摘要： This invention relates to dies and the method for making dies for rolling threaded fasteners having conical or truncated conical ends. The face of each of a pair of dies which contacts the workpiece includes a first generally planar surface having a plurality of parallel ridges disposed thereon. A second generally planar surface having ridges thereon for threading the conical or truncated conical end is disposed on the face at an angle with respect to the first generally planar surface. The face on which the two generally planar surfaces are disposed is normally generally rectangular and elongated in the direction of relative movement between a pair of dies. The intersection of the two generally planar surfaces and each groove or ridge disposed on each such surface is positioned in parallel relationship to every other ridge or groove and the intersection of the first and second generally planar surfaces. Each ridge disposed in a plane which is parallel to the first plane and the projection is disposed at an angle with respect to the direction of movement which is substantially equal to the helix angle of the threaded fastener to be formed. These angular relationships permit the rapid and inexpensive manufacture of dies for threaded fasteners of the type described by enabling cutting or grinding of the entire face with a multipoint cutting tool or a crushed grinding wheel in a single pass as opposed to prior art structures which necessitated the use of single point cutting tools or correspondingly shaped grinding wheels which machined or ground a single groove between adjacent ridges in each machining pass.
