Description

Verfahren zur Herstellung ausgekleideter lnetallkörper, insbesondere Metallrohre, durch Einpressen des Werkstoffs in bildsamem Zustande. Die bisher z. B. bei der Herstellung kunstgewerblicher Metallmöbel verwendeten Metallrohre mußten, um genügend widerstandsurnd biegefähig zu sein, eine beträchtliche Wandstärke besitzen. Die aus ihnen gefertigten Möbel waren infolgedessen entsprechend schwer und teuer.Process for the production of lined metal bodies, in particular Metal pipes, by pressing in the material in a malleable state. The previously z. B. had to use metal pipes in the manufacture of craft metal furniture, in order to be sufficiently flexible and flexible, have a considerable wall thickness. As a result, the furniture made from them was correspondingly heavy and expensive.

Die Erfindung betrifft nun ein Verfahren zur Ausfütterung von Metallkörpern, insbesondere Rohren, (die die bisher gebräuchlichen schweren Metallrohre ersetzen und dabei widerstandsfähig, leicht, formfähig, z. B. biegefähig, und billig sind. Ein solcher Körper ist jedoch nicht ausschließlich für die Herstellung von Metallmöbeln, sondern zum Ersatz von Metallstäben und Metallrohren überhaupt bestimmt, und zwar in allen den Fällen, in denen seine Anwendung Vorteil bieten kann. Es ist bekannt, Metallrohre dadurch -mit einem Mantel auszufüttern, .daß das Rohr eingespannt und in das Innere die Füllmasse in flüssigem Zustand unter Benutzung eines Dornes eingepreßt wird.The invention now relates to a method for lining metal bodies, in particular pipes (which replace the heavy metal pipes that have been used up to now and at the same time resistant, light, formable, z. B. flexible, and cheap. However, such a body is not exclusively for the manufacture of metal furniture, but intended to replace metal rods and metal pipes in general, namely in all cases in which its use can be advantageous. It is known, Metal pipes are to be lined with a jacket so that the pipe is clamped and the filling compound is pressed into the interior in a liquid state using a mandrel will.

Das Verfahren gemäß der Erfindung besteht darin, @d@aß ein Metallkörper, z. B. ein dünnwandiges, aus einem Streifen dünnen Bleches zusammengebogenes Rohr ganz oder unter Belassung eines mittleren freien Durchganges mit Steinholz unter Ausübung eines Gegendruckes auf die vordringende Masse gefüllt wird. Derartige Rohre lassen sich mit beliebigem Durchmesser und in beliebiger Wandstärke herstellen und können in beliebige Gestalt gebogen werden. Sie sind z. B. den in der chemischen Industrie Verwendung findenden Metallrohren mit Holzverkleidung infolge der Einfachheit und Billigkeit ihrer Herstellung weit überlegen .und stellen @dies-en gegenüber auch insofern .einen erheblichen technischen Fortschritt dar, als ihre Holzverkleidung fugenlos und völlig :gleichartig ist. Die Zeichnung veranschaulicht beispielsweise eine Vorrichtung zur Ausführung des Verfahrens in Anwendung auf Rohre.The method according to the invention consists in @ d @ aß a metal body, z. B. a thin-walled tube bent together from a strip of thin sheet metal completely or leaving a central free passage with stone wood underneath Exerting a counter pressure on the advancing mass is filled. Such pipes can be produced with any diameter and wall thickness and can be bent into any shape. You are e.g. B. in the chemical Industrial use metal pipes with wood cladding due to the simplicity and cheapness far superior to their manufacture. and contrast @ these-en also insofar as their wood paneling represents a considerable technical advance seamless and completely: is homogeneous. For example, the drawing illustrates a device for carrying out the method in application to pipes.

Abb. i zeigt die Vorrichtung in Seitenansicht mit :dem zu füllenden Rohre in teilweisem Schnitt, und Abb. 2 stellt den Kopf der Füllpresse für die Herstellung mit Holz verkleideter Rohre im Schnitt dar.Fig. I shows the device in side view with: the one to be filled Tubes in partial section, and Fig. 2 represents the head of the filling press for manufacture wood-clad pipes in section.

In ,der Zeichnung .ist i eine Füllpresse, die in ihrer Bauart z. B. den bekannten Kernpressen für Formereizwecke entsprechen kann und mit der bildsamen .Steinholzmasse beliebiger Zusammensetzung beschickt wird. Auf den. Kopf dieser Presse ist ein Futter 2 aufgesetzt, das zusammen mit einem Futter 6 das zu füllende Metallrohr 5 festhält. Das Futter 6 ist an einem auf einem Schlitten 13 verschiebbaren und feststellbaren Bock 14 angeordnet. Die Pressei treibt die Steinholzmasse 3 im Rohr 5 gegen die Wirkung eines in diesem liegenden Kolbens 4 vor. Letzterer wird durch ein Druckmittel, z. B. Preßluft, unter beliebigem Druck .gegen :den @Steinholzstrang gepreßt, um -diesem die gewünschte Festigkeit zu verleihen. Die Zuführung des Druckmittels erfolgt durch ein Rohr 7 und den hohlen Bock i4.In, the drawing .is i a filling press, which in its design z. B. can correspond to the known core presses for molding purposes and with the plastic ones . Stone wood mass of any composition is charged. On the. Head this A feed 2 is placed on the press, which together with a feed 6 is the one to be filled Metal tube 5 holds. The chuck 6 is slidable on a slide 13 and lockable bracket 14 arranged. The Pressei drives the stone wood mass 3 in Tube 5 against the action of a piston 4 lying in it. The latter will by a pressure medium, e.g. B. compressed air, under any pressure. Against: the @ stone wood strand pressed to give it the desired strength. The supply of the pressure medium takes place through a pipe 7 and the hollow block i4.

Ein das zu verkleidende Rohr io und den hohlen Preßstempel 12 durchsetzender Bolzen 8 findet Anwendung, -wenn in der Steinholzmasse ein freier Durchgang vorhanden sein soll (Abb. 2).A pipe to be covered io and the hollow ram 12 penetrating Bolt 8 is used if there is a free passage in the stone wood mass should be (Fig. 2).
