gewindewalzverfahren and gewindewalzvorrichtung to produce a thread

摘要

the invention concerns a gewindewalzverfahren and gewindewalzvorrichtung (15) to produce a thread (17) on a workpiece (16).this is a umformwerkzeug (19) with a umformprofil (22) is used that has a profilsteigungswinkel (d).the profilsteigungswinkel (a) is dependent on the manufactured nominal diameter (dn) and manufactured nenngewindesteigung (hn) is calculated.during the umformens rolls over the workpiece (16) by a rotation about its longitudinal axis (l) of the umformprofil (22), whereby the thread (17) is manufactured.in order to create threads (17) with diameters from the nominal diameter (dn) distinguishthe workpiece (16), a axialbewegung in axialrichtung (a) parallel to its longitudinal axis (l) on the workpiece (16) relative to the umformprofil (22) in axialrichtung (a) moveswhile the workpiece (16) to shift.
