KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das vorliegende Verfahren bezieht sich auf das Ineinanderfügen zweier Metalle, die durch Walzen zugleich eine Umgestaltung erfahren, um zur Herstellung von Geschofsmänteln für Gewehre, Blumendraht oder dergl. verarbeitet zu werden.The present method relates to the joining of two metals by Rollers also underwent a redesign in order to produce storey jackets for Rifles, floral wire or the like. To be processed.
Bisher wurde (Fig. 1) der Kupfermantel a um den aus Eisen, Stahl oder dergl. bestehenden Kern b herumgegossen und alsdann wurden beide Metalle gewalzt. In diesem Falle mufsten die Enden des Kernes b weit aus dem Kupfermantel herausragen, weil der letztere beim Walzen in der Breitenrichtung sich sehr stark ausdehnte.So far (Fig. 1) the copper jacket a was cast around the core b made of iron, steel or the like, and then both metals were rolled. In this case, the ends of the core b must protrude far from the copper jacket because the latter expanded very greatly in the width direction during rolling.
Nach dem vorliegenden Verfahren wird durch den vollen Kupfercylinder α mittelst hydraulischen oder sonstigen starken Druckes ein Loch zur Aufnahme des Kernes b hindurchgetrieben, und bei dieser Bearbeitung hndet ein sehr starkes Zusammenpressen des Kupfermantels selbst statt. Die hierdurch erzielte gröfsere Dichtigkeit des Kupfermantels ermöglicht die Anwendung eines kürzeren Kernes b, da der Kupfermantel beim Walzen nicht mehr eine so starke Ausdehnung erfährt, wie der gegossene Kupfermantel nach dem bisherigen Verfahren. According to the present method, a hole for receiving the core b is driven through the full copper cylinder α by means of hydraulic or other high pressure, and during this processing the copper jacket itself is pressed together very strongly. The greater tightness of the copper jacket achieved in this way enables a shorter core b to be used, since the copper jacket no longer expands as much during rolling as the cast copper jacket according to the previous method.
Zugleich erreicht man den wesentlichen Vortheil, dafs man ein tadelloses Fabrikat erhält, während das nach dem bisherigen Verfahren hergestellte Product häufig Fehler, die sogen. »Perlen«, aufweist.At the same time one achieves the essential advantage that one obtains an impeccable product, while the product manufactured by the previous method often errors, the so-called. "Pearls".
Claims (1)
Verfahren zur Herstellung von auszuwalzenden Werkstücken aus Verbundmetall, dadurch gekennzeichnet, dafs in einen Vollcylinder (a) von weicherem Metall das zur Aufnahme des härteren Kernmetalles dienende Loch unter starkem Druck eingeprefst wird, so dafs hierbei zugleich ein starkes Zusammenpressen des äufseren Metalles erfolgt.PATENT CLAIMS:
Process for the production of workpieces to be rolled out of composite metal, characterized in that the hole serving to accommodate the harder core metal is pressed into a full cylinder (a) of softer metal under strong pressure, so that at the same time a strong compression of the outer metal takes place.
