Die module set for pressing tools for producing screws

Abstract

A die module set ( 1 ) for a pressing tool for producing screws, threaded bolts and ball pins includes two different cores ( 5, 14 ) and two different reinforcement rings ( 8, 11 ) being designed to be coordinated in a way that a first die ( 2 ) including a first core ( 5 ) and the reinforcement rings ( 8, 11 ) or alternatively a second die ( 2 ) including the other core ( 14 ) and only one of the reinforcement rings ( 11 ) can be composed thereof.

I claim: 
     
         1 . A die module set for a pressing tool, comprising:
 a first core including a first inner diameter and a first outer diameter;   a second core including a second inner diameter and a second outer diameter, the second outer diameter of the second core being greater than the first diameter of the first core;   a first reinforcement ring having a third inner diameter and a third outer diameter, the third outer diameter of the first reinforcement ring being identical to the second outer diameter of the second core; and   a second reinforcement ring having a fourth inner diameter and a fourth outer diameter,
 the first outer diameter of the first core and the third inner diameter of the first reinforcement ring as well as the third outer diameter of the first reinforcement ring and the fourth inner diameter of the second reinforcement ring being coordinated in a way that a first die including the first core, the first reinforcement ring and the second reinforcement ring can be composed thereof, and 
 the second outer diameter of the second core and the fourth inner diameter of the second reinforcement ring being coordinated in a way that alternatively a second die including the second core and the second reinforcement ring, but not including the first reinforcement ring can be composed thereof. 
   
     
     
         2 . The die module set of  claim 1 , wherein the second inner diameter of the second core is greater than the first inner diameter of the first core. 
     
     
         3 . The die module set of  claim 1 , wherein
 the first outer diameter of the first core and the third inner diameter of the first reinforcement ring are coordinated in a way that they can be connected to one another by forming a press fit; and   the third outer diameter of the first reinforcement ring and the fourth inner diameter of second reinforcement ring are coordinated in a way such that they can be connected to one another by forming a press fit.   
     
     
         4 . The die module set of  claim 2 , wherein
 the first outer diameter of the first core and the third inner diameter of the first reinforcement ring are coordinated in a way that they can be connected to one another by forming a press fit; and   the third outer diameter of the first reinforcement ring and the fourth inner diameter of second reinforcement ring are coordinated in a way such that they can be connected to one another by forming a press fit.   
     
     
         5 . The die module set of  claim 1 , wherein
 the first reinforcement ring has a first thickness; and   the second reinforcement ring has a second thickness, the second thickness being greater than the first thickness.   
     
     
         6 . The die module set of  claim 5 , wherein the ratio between the thicknesses and the inner diameters of the reinforcement rings is between approximately 5 and 25%. 
     
     
         7 . The die module set of  claim 1 , wherein the cores include a plurality of segments being divided in an axial direction. 
     
     
         8 . The die module set of  claim 1 , further comprising
 a third core, the third core being different than the first core and the second core; and   a third reinforcement ring, the third reinforcement ring being different than the first reinforcement ring and the second reinforcement ring.   
     
     
         9 . The die module set of  claim 8 , wherein
 the three cores have different inner diameters and different outer diameters; and   the three reinforcement rings have different inner diameters and different outer diameters.   
     
     
         10 . The die module set of  claim 1 , wherein the dies are cold extrusion dies of a machine-driven press. 
     
     
         11 . The die module set of  claim 1 , wherein the dies are designed to produce screws. 
     
     
         12 . A die module set kit for a pressing tool, comprising:
 a first die module set of  claim 1 ; and   a second die module set of  claim 1 , the cores and the reinforcement rings of the second die module set being designed to be different than the cores and the reinforcement rings of the first die module set.   
     
     
         13 . The die module set kit of  claim 12 , wherein
 the cores and the reinforcement rings of the second die module set have different outer diameters than the cores and the reinforcement rings of the first die module set; and   the cores and the reinforcement rings of the second die module set have other inner diameters than the cores and the reinforcement rings of the first die module set.   
     
     
         14 . The die module set kit of  claim 12 , further comprising
 a third die module set of  claim 1 , the cores and the reinforcement rings of the third die module set being designed to be different than the cores and the reinforcement rings of the first die module set and of the second die module set.
