Description

Schwalbungen für die Formen von Brikettpressen und ähnliche Preßformen, die einer großen Abnutzung unterworfen sind. In der Brikettindustrie sind Preßformen in Verwendung, die, damit sie der unter großem Druck stattfindenden Abnutzung möglichst lange widerstehen, aus einem besonders harten Stahl hergestellt werden.Dovetailing for the shapes of briquette presses and similar molds, which are subject to great wear and tear. In the briquette industry there are compression molds in use that, so that they can withstand the wear and tear taking place under great pressure as much as possible withstand long, be made of a particularly hard steel.

Manche Preßformen, die dünne Kanten aufweisen (eine einzelne Wandung solcher Formen führt die Bezeichnung »Schwalbung«), haben bei Verwendung eines ungewöhnlich harten Stahles den Nachteil, daß beim Pressen Kantenbrüche entstehen, welche die Preßform nach kürzester Zeit schon unbrauchbar machen.Some dies that have thin edges (a single wall Such forms are called »swallowing«), when using an unusual hard steel has the disadvantage that edge breaks occur when pressing, which the Make the mold unusable after a very short time.

Um diesem übelstande abzuhelfen, wird gemäß der Erfindung nur der die größte Widerstandsfähigkeit gegen Abnutzung erfordernde mittlere Teil der Schwalbung aus hartem Stahl hergestellt, während die mit scharfen Kanten versehenen Randteile .der Schwalbumgen aus einem. weicheren und zäheren Stahl hergestellt und mit dem mittleren Teil durch bekannte Mittel, wie Angießen, Schweißen, Löten, Verschrauben o. dgl., verbunden werden.In order to remedy this inconvenience, according to the invention, only the middle part of the dovetail that requires the greatest resistance to wear made of hard steel, while the edge parts provided with sharp edges .the swallows from one. made of softer and tougher steel and with the middle part by known means, such as casting, welding, soldering, screwing or the like., are connected.

Die Zeichnung zeigt als Ausführungsbeispiel der Erfindung den Querschnitt nebst Oberansicht einer Schwalbung, bei welcher der die größte Widerstandsfähigkeit erfordernde Mittelteil a aus hartem Stahl, und die Seitenteile b und c, bei welcher die Gefahr der Kantenbrüche besteht, aus einem weicheren und zäheren Stahl hergestellt sind.As an embodiment of the invention, the drawing shows the cross-section and top view of a dovetail, in which the middle part a, which requires the greatest resistance, is made of hard steel, and the side parts b and c, in which there is a risk of edge breaks, are made of a softer and tougher steel .

Es ist diese Ausführungsweise natürlich auch für alle anderen, unter ähnlichen Voraussetzungen arbeitende Preßformen anwendbar.It is, of course, the same for everyone else, under Similar conditions working press molds applicable.

PATENT-ANSPRUcH: Schwalbung für Formen von Brikettpressen und ähnliche Preßformen, welche einer großen Abnutzung unterworfen sind, dadurch gekennzeichnet, daß nur der die größte Widerstandsfähigkeit gegen Abnutzung erfordernde mittlere Teil der Schwalbung aus hartem Stahl besteht, während die mit scharfen Kanten versehenen, mit dem mittleren Teil- durch Angießen, Schweißen, Löten o. dgl. in sonst bekannter Weise verbundenen Randteile der Schwalbung aus einem weicheren, zähen Stahl hergestellt sind. PATENT CLAIM: Dovetail joint for molds of briquette presses and similar press molds which are subject to great wear and tear, characterized in that only the central part of the dovetail joint, which requires the greatest resistance to wear, is made of hard steel, while those provided with sharp edges are made of hard steel middle part by casting, welding, soldering or the like. Edge parts of the dovetail connected in an otherwise known manner are made of a softer, tough steel.
