Description

Die Erfindung bezieht sich auf Matrizen für die Flerstellttng von Preßteilen und insonderheit auf eine Matrize für die Herstellung ri:fenfreier Preßteife,die sich von den bisher für den besagten Zweck gebräuchlichen Matrizen dadurch unterscheidet, (laß sie aus zwei verschiedenen Werkstoffen besteht.The invention relates to matrices for the production of Pressed parts and, in particular, a die for the production of tear-free pressed parts, the differs from the matrices previously used for this purpose in that (Let it be made of two different materials.

Bei der Herstellung von Preßteilen,1)eispielsweise beim Pressen von Behälter- und Kesselböden, be-(lietit inan sich bekanntlich sogenannter, von einem Fundani@rit oder sonstigem Stützkörper getragener, denn herzustellenden Preß.teil entsprechenderUnterringc (Matrizen), die in der Regel aus Gratlg'uß oder auch aus Stahl bestehen. Unterringe aus Grauguß hallen den Nachteil, daß sie keine genügende Bruchfestigkeit aufweisen und daher «'ihrend des Preßvorganges häutig zu Bruch gehen, während Stahlringe den Nachteil haben, claß sie beine Pressen beispielsweise von Behälter- und Kesseli>öcien starke Riefen am Außenbord des Bodens hervorrufen, die sich bei der Verwendung von Graugußringen praktisch nicht bilden.In the manufacture of pressed parts, 1) for example when pressing Container and boiler bottoms, as is well known, are of one Fundani @ rit or other supporting body worn, because pressed part to be produced Corresponding Unterringc (matrices), which are usually made of Gratlg'uss or from Made of steel. Lower rings made of gray cast iron have the disadvantage that they are insufficient Have breaking strength and therefore often break at the end of the pressing process, while steel rings have the disadvantage that they can be used with presses, for example Containers and kettles cause strong grooves on the outer edge of the bottom, which practically do not form when using gray cast iron rings.

Ltin nun die den beiden erwähnten Matrizen innewohnenden Vorteile unter Vermeidung derer Nachteile zu vereinen, schlägt die vorliegende Erfindung vor, den 1VIatrizenring aus zwei verscliiedenen Werkstoffen herzustellen, indem ein Matrizenring aus Grauguß in seinem Innern mit ein-in Ring aus Schmiedeeisen verstärkt wird, der in den Graugußring eingegossen, eingelegt oder auch vorn Graugußeisen umgossen wird, so daß auf diese WeisebeideRinge innig miteinander verbunden sind. Durch die Verbindung der beiden Ringe verschiedelien \\"erkstoffes miteinander wird die Bruchgefahr des äußeren Graugußringes weitgehend 1reseitigt, so (laß derartige Matrizenringe den hierzu gestellten Anforderungen in beitig auf Vermeidung der Riefenl>ildung an den @r<l@stüclcen und Beseitigung der Bruchgefahr für (len \latrizenring voll und ganz gerecht werd-n.Ltin now the advantages inherent in the two matrices mentioned To combine while avoiding their disadvantages, proposes the present invention propose to manufacture the male matrix ring from two different materials by a die ring made of gray cast iron inside with a one-in ring made of wrought iron is reinforced, which is poured into the gray cast iron ring, inserted or also in front of gray cast iron is poured around, so that in this way both rings are intimately connected. Through the connection of the two rings, different materials are created the risk of breakage of the outer gray cast iron ring is largely eliminated, so (leave such Die rings meet the requirements set for this purpose in order to avoid the formation of grooves on the @r <l @ pieces and elimination of the risk of breakage for (len \ latrizenring full and become quite fair.
