Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Ingots in der Weise, dafs in eine dem herzustellenden Gegenstände entsprechende Form mit Sand oder einem anderen nicht metallischen Material gefüllte Kästen angebracht werden, deren Mantelflächen das eingegossene Material begrenzen. Diese Ingots kann man dann zu Achsen, Trägern u. dergl. weiter verarbeiten oder direct zu baulichen oder sonstigen Zwecken verwenden.The present invention relates to a method for producing ingots in such a way that into a shape corresponding to the object to be produced with sand or another Boxes filled with non-metallic material are attached, the outer surfaces of which have the Limit poured material. These ingots can then be turned into axles, carriers and the like. further process or use directly for structural or other purposes.

Auf beiliegender Zeichnung stellen Fig. 1, 6 und 8 für die Ausführung des vorliegenden Verfahrens geeignete Formen dar, während Fig. 4 und 5 ' die mit Sand gefüllten Kästen veranschaulichen und Fig. 2, 3, 7, 9 bis 11 die in jenen Formen hergestellten Ingots zeigen. Wie aus Fig. 1 zu ersehen, ist auf einer Platte A eine Form Ax angebracht und in dieser auf Füfsen α ein' Kasten al aufgestellt. Der Mantel dieses Kastens α1, Fig. 4 und 5, besteht aus Eisenblech oder einem anderen geeigneten Material, erhält eine geringere Höhe als die Form A1 und schliefst Sand αχ oder eine sonstige nicht metallische Masse ein. Die innerhalb der Form A1 einzunehmende Lage des Kastens a1 richtet sich nach der Dicke der vorgeschriebenen Wandungen. Bei solchen Gegenständen, welche später zwischen Walzen oder einem Hammer weiter verarbeitet werden, stellt man den Kasten zweckmäfsig in die Mitte der Form. Die Füfse α werden aus einem dem anzufertigenden Körper entsprechenden Material hergestellt, oder es werden an Stelle der Füfse α Platten d, Fig. 5, 6 und 8, angewandt, welche entweder in dem unteren Theile des Kastens a\ Fig. 5, oder unterhalb des letzteren, Fig. 6 und 8, angebracht werden. Soll der Ingot zwei oder mehrere Kästen erhalten, Fig. 7, 9 und 9a, so ordnet man die Kästen nach Fig. 6 über einander oder nach Fig. 8 neben einander an.In the accompanying drawings, Figures 1, 6 and 8 show suitable molds for practicing the present method, while Figures 4 and 5 'show the boxes filled with sand and Figures 2, 3, 7, 9-11 show those in those molds show manufactured ingots. As can be seen from Fig. 1, a form A x is attached to a plate A and a box a l is set up in this on feet α. The jacket of this box α 1 , Fig. 4 and 5, consists of sheet iron or another suitable material, has a lower height than the shape A 1 and includes sand α χ or some other non-metallic mass. The position of the box a 1 to be assumed within the form A 1 depends on the thickness of the prescribed walls. For such objects, which are later processed further between rollers or a hammer, the box is expediently placed in the middle of the mold. The feet α are made of a material corresponding to the body to be made, or plates d, Figs. 5, 6 and 8, are used in place of the feet α , which are either in the lower part of the box a \ Fig. 5, or below of the latter, Figs. 6 and 8, can be attached. If the ingot is to receive two or more boxes, FIGS. 7, 9 and 9a, the boxes according to FIG. 6 are arranged one above the other or according to FIG. 8 next to one another.

Bei der in Fig. 11 dargestellten Säule ist eine faijonnirte, aus plastischem Material angefertigte Form verwendet worden, während Fig. 10 ein Eisenbahnrad veranschaulicht, welches einen als Ring ausgebildeten Kasten ax in sich schliefst.When in Fig. Pillar 11 illustrated has been used a faijonnirte arrangements made of plastic material shape, while Fig. 10 illustrates a railway wheel, which asleep formed as a ring box a x in itself.

Claims (1)

Patent-Anspruch:Patent claim: Verfahren zur Herstellung von Gufsstücken, welche ein geringeres specifisches Gewicht haben als das Material, aus welchem dieselben gegossen werden, darin bestehend, dafs in eine Giefsform ein Kasten oder mehrere Kästen mit nicht metallischer Füllung eingesetzt und dann mit schmiedbarem Gufsmetall vollständig umgössen werden.Process for the production of castings which have a lower specific gravity have, as the material from which they are cast, consist in the fact that they are in a Giefsform a box or several boxes with non-metallic filling inserted and then completely encapsulated with forgeable cast metal.
