  Verfahren zur Herstellung von Hartmetallmatrizen 
 EMI1.1 
 



   In den Zeichnungen ist die Herstellung einer Pressmatrize in der Fig. 1 perspektivisch und in Fig. 2 in einem senkrechten Querschnitt dargestellt. Fig. 3 zeigt perspektivisch ein einzelnes Segment. Der Matrizenkörper ist zusammengesetzt aus einzelnen Segmenten 1 und 2. Diese   Segmente   und 2 sind, wie in Fig. 3 für ein Segment der Form 1 gezeigt, an den Enden mit Nuten 3 versehen. Diese Nuten ergänzen sich zu einer Ringnut, wenn die einzelnen bearbeitenden Segmente zusammengesetzt werden. In diese Ringnut wird, nachdem die einzelnen Segmente zweckmässigerweise auf einen Kern 4 zusammengesetzt sind, je ein Stahlring 5 eingeschrumpft. 



  Sodann wird die zylindrische Oberfläche des Matrizenkörpers überschliffen, wobei der Körper in den Spitzen einer Drehbank ruht. Die Körner 6 für diese Befestigung befinden sich in dem Kern. 



   Nachdem die Bearbeitung der zylindrischen Mantelfläche auf diese Weise vorgenommen worden ist, wird der Körper in den Stahlmantel 7 (Fig. 2) eingschrumpft.

  Process for the production of hard metal matrices
 EMI1.1
 



   In the drawings, the production of a press die is shown in perspective in FIG. 1 and in a vertical cross section in FIG. 2. Fig. 3 shows a single segment in perspective. The die body is composed of individual segments 1 and 2. These segments and 2 are, as shown in FIG. 3 for a segment of the mold 1, provided with grooves 3 at the ends. These grooves complement each other to form an annular groove when the individual machining segments are assembled. After the individual segments are expediently assembled onto a core 4, a steel ring 5 is shrunk into this annular groove.



  The cylindrical surface of the die body is then ground, the body resting in the tips of a lathe. The grains 6 for this attachment are in the core.



   After the machining of the cylindrical jacket surface has been carried out in this way, the body is shrunk into the steel jacket 7 (FIG. 2).

PATENTANSPRUCH : Verfahren zur Herstellung von Hartmetallmatrizen, die aus einzelnen Segmenten zusammengesetzt und in einem Stahlmantel eingeschrumpft werden, dadurch gekennzeichnet, dass die Enden der Segmente mit einer Nut versehen werden, die sich beim Zusammensetzen der Segmente zu einer Ringnut ergänzen, in die je ein Stahlring eingeschrumpft wird, ehe die zweckmässigerweise auf einem Kern zusammengesetzten Segmente überschliffen und in den Stahlmantel eingeschrumpft werden. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of hard metal matrices which are assembled from individual segments and shrunk into a steel jacket, characterized in that the ends of the segments are provided with a groove which, when the segments are assembled, complement each other to form an annular groove into which a steel ring is shrunk before the segments, which are expediently assembled on a core, are ground and shrunk into the steel jacket. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
