Description
In dem Patent 1 046 449 ist ein Verfahren und eine Vorrichtung zum aluminothermischen Zwischengußschweißen von Werkstücken, vorzugsweise Schienen, unter Schutz gestellt, die die für die Zwischengußscbweißung erforderliche Zeit stark vermindern.In patent 1,046,449 there is a method and apparatus for aluminothermic inter-cast welding of workpieces, preferably rails, placed under protection that are necessary for the inter-cast welding greatly reduce the time required.
Die Vorrichtung ist gekennzeichnet durch an einem anderen Ort vorgefertigte, aus feuerfestem Werkstoff bestehende Formkörper, die vorteilhafterweise in Einsatzkästen eingesetzt sind, durch eine Schnellspannvorrichrung zum Anpressen der Formkörper an die zu schweißenden Werkstücke und durch oberhalb der Formkörper angeordnete Vorwärmebrenner.The device is characterized by prefabricated at another location, made of refractory material existing moldings, which are advantageously used in insert boxes, by a Schnellspannvorrichrung for pressing the molded body against the workpieces to be welded and through above the Preheat burners arranged in a molded body.
Bei der Weiterausbildung der geschützten Vorrichtung wurde nunmehr gefunden, daß es einen beachtlichen technischen Fortschritt bedeutet, wenn die andernorts vorgefertigten, aus feuerfestem Werkstoff bestehenden Formkörper, die getrocknet oder gebrannt sein können und daher eine genügende Standfestigkeit besitzen, ohne Gefahr einer Rißbildung unter Fortfall der Hilfs- und Einsatzkästen fest an die zu schweißenden Werkstücke, z. B. Schienen·, allein oder unter Zwischenschaltung eines Stützrahmens, der die Form des Einsatzkastens hat, angesetzt werden. Die an den Anlageflächen mit Dichtungsnuten oder abgeflachten Kanten versehenen Gießformen werden mit beliebigen Dichtungsmitteln, wie Formsandbrei oder feuerfestem Kitt oder mittels ein- oder anzulegender Asbestschnüren, gegen das zu schweißende Werkstück abschnüre, gegen das zu schweißende Werkstück gestaltete Stützrahmen dient dazu, den durch die Schnellspannvorrichtung auf die Gießformrückwand ausgeübten Druck auszugleichen.In the further training of the protected device it has now been found that it represents a considerable technical advance if the elsewhere prefabricated molded bodies made of refractory material that are dried or fired can be and therefore have sufficient stability without the risk of cracking and loss the auxiliary and insert boxes firmly to the workpieces to be welded, e.g. B. Rails, alone or under Interposition of a support frame, which has the shape of the insert box, can be applied. The Andes Casting molds provided with sealing grooves or flattened edges can be made with any Sealing agents, such as molding sand paste or fire-proof putty or by means of asbestos cords that are to be laid in or put on, cord against the workpiece to be welded, designed against the workpiece to be welded The support frame serves to reduce the pressure exerted on the rear wall of the mold by the quick-release device Equalize pressure.
