    Schwalbumgen für   die   Brikettfabrikation   und   ähnliche Pressformen ;   die einer grossen
Abnutzung unterworfen sind. 



   In der Brikettindustrie sowie in anderen Industrien, in welchen Presslinge unter hohem Druck erzeugt werden, sind Pressformen in Verwendung, die, damit sie der unter grossem Druck stattfindenden Abnutzung möglichst lange widerstehen, aus einem besonders harten Stahl hergestellt werden. 



   Bei manchen   Pressformen, wie   z. B. bei den in der Brikettfabrikation verwendeten   sogenannten   Schwalbungen, welche dünne Kanten aufweisen, hat die Verwendung eines ungewöhnlich harten Stahls den Nachteil, dass beim Pressen   Eantenbrüche   entstehen, welche die Pressform nach kürzerer Zeit schon unbrauchbar machen. 



   Um diesem Übelstande abzuhelfen, wird gemäss vorliegender Erfindung nur der die grösste Wider-   standfähigkeit   gegen Abnutzung erfordernde mittlere Teil der Schwalbung aus Hartstahl hergestellt. während die mit scharfen   Kanten versehenen Randteile der Schwalbungen aus   einem weicheren und zähen Stahl hergestellt und mit dem mittleren Teil durch bekannte Mittel, wie Angiessen,   Schweissen.   



  Löten, Verschrauben verbunden werden. 



   Die Zeichnung zeigt als Ausführungsbeispiel der vorliegenden Erfindung den Querschnitt einer   Sehwalbung,   bei welcher der die grösste Widerstandsfähigkeit erfordernde   Mittelteil a aus Hartstahl   und die Seitenteile bund c wegen der Gefahr von   Kantenbrüchen   aus einem weicheren und zäheren Stahl hergestellt sind. 



   Es ist diese Ausführungsweise natürlich auch für alle andern unter   ähnlichen   Voraussetzungen arbeitende Pressformen oder   ähnlich   beanspruchte Maschinenteile anwendbar. 



   PATENT-ANSPRÜCHE :
1. Schwalbungen für die Brikettfabrikation und ähnliche Pressformen, die einer grossen Abnutzung unterworfen und der Gefahr von Kantenbrüehen ausgesetzt sind, dadurch gekennzeichnet, dass sie aus mehreren Teilen, die durch Angiessen, Schweissen, Löten, Verschrauben od. dgl. miteinander verbunden werden, hergestellt sind.

    Dovetails for the manufacture of briquettes and similar molds; that of a big one
Are subject to wear and tear.



   In the briquette industry and in other industries in which compacts are produced under high pressure, compression molds are used which are made from a particularly hard steel so that they can withstand the wear and tear that takes place under great pressure for as long as possible.



   In some molds, such as B. in the so-called swallows used in briquette manufacture, which have thin edges, the use of an unusually hard steel has the disadvantage that when pressing, broken edges occur, which make the mold unusable after a short time.



   In order to remedy this inconvenience, according to the present invention only the middle part of the dovetail which requires the greatest resistance to wear is made of high carbon steel. while the edge parts of the swallows provided with sharp edges are made of a softer and tough steel and are connected to the central part by known means such as casting, welding.



  Soldering, screwing together.



   The drawing shows, as an embodiment of the present invention, the cross-section of a visual curvature in which the central part a, which requires the greatest resistance, is made of high carbon steel and the side parts c are made of a softer and tougher steel because of the risk of edge breaks.



   This embodiment can of course also be used for all other press molds or similarly stressed machine parts that work under similar conditions.



   PATENT CLAIMS:
1. Swallows for briquette production and similar press molds that are subject to great wear and tear and are exposed to the risk of edge brewing, characterized in that they are made from several parts that are connected to one another by casting, welding, soldering, screwing or the like are.
