Abstract

The thread former is used for the non-cutting shaping of threads and has a main body ( 1′ ) on which the moldings ( 6 ) are provided, distributed over the circumference. Said moldings are provided with thread-forming teeth ( 13, 14 ). Profile grinding tools are used to produce the thread-forming teeth ( 13, 14 ), both in the main body ( 1′ ) as well as in the moldings ( 6 ). In order for the thread former to be produced easily and cost-effectively, the moldings ( 6 ) protrude radially beyond the main body ( 1′ ) so far that the profile tool only engages with the molding when producing the thread-forming teeth ( 13, 14 ). Consequently, the profiling tool only has to machine one type of material. The thread former is used for the non-cutting shaping of threads, particularly of internal threads.

Claims

exact text as granted — not AI-modified
1 .- 13 . (canceled) 
     
     
         14 . A thread former comprising:
 a main body;   moldings distributed about a circumference of the main body and provided with thread-forming teeth;   wherein the moldings project radially so far past the main body that a profiling tool during manufacture of the thread-forming teeth engages only the moldings.   
     
     
         15 . The thread former according to daim  14 , wherein the main body has receiving grooves and the moldings are fastened in the receiving grooves. 
     
     
         16 . The thread former according to daim  14 , wherein the moldings each have a longitudinal center plane and are embodied symmetrical relative to the longitudinal center plane. 
     
     
         17 . The thread former according to daim  14 , wherein the moldings each have a longitudinal center plane and are embodied asymmetrical relative to the longitudinal center plane. 
     
     
         18 . The thread former according to  claim 14 , wherein the moldings are arranged axis-parallel to an axis of the main body. 
     
     
         19 . The thread former according to  claim 14 , wherein the moldings are positioned at an angle relative to an axial plane of the main body. 
     
     
         20 . The thread former according to  claim 14 , wherein the moldings, viewed in a side view, are positioned at an angle relative to a longitudinal axis of the main body. 
     
     
         21 . The thread former according to  claim 14 , wherein the moldings extend spirally about the main body. 
     
     
         22 . The thread former according to  claim 14 , wherein the moldings are arranged uniformly distributed about the circumference of the main body. 
     
     
         23 . The thread former according to  claim 14 , wherein the moldings are arranged non-uniformly distributed about the circumference of the main body. 
     
     
         24 . The thread former according to  claim 14 , wherein the moldings are symmetrically arranged relative to an axial plane of the main body. 
     
     
         25 . The thread former according to  claim 14 , wherein the moldings are arranged such that a longitudinal center plane of the moldings is positioned at an acute angle relative to an axial plane of the main body. 
     
     
         26 . The thread former according to daim  14 , comprising an inner cooling medium supply.
