Description
Man kennt bereits für Gießereizwecke bestimmte Kernstützen, die aus einem in Doppel-T-Form gebogenen Bandeisenstück bestehen. Um die Tragplatten solcher Kernstützen nach beiden Seiten gleich stark zu machen, kann man das Bandeisen mehrfach übereinanderfalzen.One already knows certain core supports for foundry purposes, which consist of a double-T-shape bent piece of band iron. In order to increase the support plates of such core supports equally on both sides you can fold the band iron over each other several times.
Die Verwendung von solchen Kernstützen führt indessen verschiedene Übelstände mit sich. Für die Herstellung der Kernstützen wird verhältnismäßig viel Material gebraucht, und ein Teil desselben ist von keinem nennenswerten Nutzen.The use of such core supports, however, leads to various drawbacks themselves. A relatively large amount of material is needed to manufacture the core supports, and part of it is of no use to speak of.
Nach der Erfindung wird die Kernstütze aus Metalldraht hergestellt, wobei die zwei Tragflächen der Stützen dadurch gebildet werden, daß der Draht in Form von Spiralen aufgewickelt wird, die mittels eines aus dem Draht gebildeten Halses in dem gewünschten gegenseitigen Abstand gehalten werden. Das eine Ende des Drahtes ist rechtwinklig zu der einen Tragfläche umgebogen und dient, indem es in den Formsand gesteckt wird, dazu, die Kernstütze in diesem festzuhalten. z5 Die Erfindung führt außer Ersparnis an Material und außer der Zuverlässigkeit in der Aufstellung der Kernstütze zugleich den Vorteil mit sich, daß das- geschmolzene Eisen zwischen die Windungen i.n den Spiralen, die die Tragfläche bilden, hineinfließt, so daß eine innige Verbindung zwischen dem gegossenen Gegenstand und der Kernstütze gebildet wird.According to the invention, the core support is made of metal wire, the two Support surfaces of the supports are formed in that the wire is wound in the form of spirals which are held in the desired mutual distance by means of a neck formed from the wire. That one end of the wire is bent at right angles to the one wing and is used by it is inserted into the molding sand to hold the core support in it. z5 The invention cites besides savings Material and apart from the reliability in the installation of the core support at the same time the advantage with it that the molten iron between the turns in the spirals that the Form wing, flows into it, so that an intimate connection between the cast Object and the core support is formed.
Eine Ausführungsform der Erfindung ist in der Zeichnung dargestellt, woAn embodiment of the invention is shown in the drawing, where
Fig. ι die Kernstütze vom Ende gesehen undFig. Ι the core support seen from the end and
Fig. 2 dieselbe von der Seite gesehen darstellt. Figure 2 shows the same seen from the side.
Die aus Metalldraht hergestellte Kernstütze besteht aus zwei Tragflächen 3 und 4, die durch spiralförmige Aufwicklung des Drahtes gebildet sind. Die zwei Tragflächen sind durch ein Zwischenstück oder einen Hals 5 aus einem einfachen Draht verbunden. Das eine Drahtende 6 ist von der einen Fläche 3 rechtwinklig gebogen und dient dazu, beim Ein- , stecken in den Formsand die Kernstütze an Ort und Stelle zu halten.The core support made of metal wire consists of two wings 3 and 4, the are formed by spirally winding the wire. The two wings are connected by an intermediate piece or neck 5 made of a simple wire. The one Wire end 6 is bent at right angles from one surface 3 and is used to stick in the molding sand to hold the core support in place.
