Verbindung von Metallgegenständen.Connection of metal objects.

Patentiert im Deutschen Reiche vom 26. August 1921 ab.Patented in the German Empire on August 26, 1921.

Die Erfindung erstreckt sich auf solche Verfahren zur Verbindung von Metallgegenständen, bei denen ein hoher Flüssigkeitsdruck zur Anwendung gelangt. Diesen bekannten Verfahren gegenüber besteht die Erfindung darin, daß die in einem Flüssigkeitsbehälter aufeinandergelegten Metallkörper durch die Druckflüssigkeit, welche durch Erhitzung auf eine dem Schmelzpunkt des einen Metalles naheliegende Temperatur gebracht wird, erwärmt werden. Gemäß diesem Verfahren lassen sich nicht nur Hohlgefäße von starker, sondern auch, solche von beliebig dünner Wandung sowie auch anders geformteThe invention extends to such methods of joining metal objects, where high fluid pressure is used. The invention is based on these known methods in that the metal bodies placed one on top of the other in a liquid container by the pressure fluid, which by heating to one of the melting point of one Metal is brought close to temperature, be heated. According to this procedure Not only can hollow vessels of strong, but also, those of arbitrary thin walls as well as differently shaped ones

Gegenstände, wie Platten, flache Schalen u. dgl., behandeln.Handle objects such as plates, shallow bowls and the like.

Ah Druckflüssigkeit kommen außer Wasser namentlich indifferente Kohlenwasserstoffe, z. B. Solaröl, Ester, wie Phthalsäureester, Kresylester, Glyzerin usw., in Betracht; ihre Auswahl richtet sich nach dem Schmelzpunkt der zu verbindenden Metalle.In addition to water, there are also indifferent hydrocarbons, z. B. solar oil, esters such as phthalic acid ester, cresyl ester, glycerine, etc., into consideration; their The selection depends on the melting point of the metals to be joined.

Die Zeichnung veranschaulicht eine zur ίο Durchführung des Verfahrens dienende Vorrichtung im senkrechten Schnitt.The drawing illustrates a device used to carry out the method in vertical section.

Gemäß der Abbildung besteht die Vorrichtung aus dem Druckbehälter d, der mit dem Manometer g, dem Thermometer h und dem Sicherheitsventil k versehen ist. Mit dem Inneren des Behälters d ist die Druckpumpe e durch eine Leitung in Verbindung gebracht, in die das Absperrventil i eingeschaltet ist. Unter dem Behälter befindet sich die Feueao rung /.According to the figure, the device consists of the pressure vessel d, which is provided with the manometer g, the thermometer h and the safety valve k . The pressure pump e is connected to the interior of the container d through a line in which the shut-off valve i is switched on. The fire alarm / is located under the container.

Gemäß dem neuen Verfahren wird mit dieser Vorrichtung in folgender Weise gearbeitet: According to the new method, this device is used in the following way:

Der Gegenstand a, der im dargestelltenThe subject a, which is shown in

as Falle vertieft ist, wird mit den entsprechend geformten Metallen b und c ausgelegt, wobei natürlich die sich berührenden Metallflächen metallisch rein sein müssen, und sodann in den Behälter d eingebracht. Darauf wird mittels der Pumpe e Druckflüssigkeit in den Behälter, hineingepumpt, so daß der Gegenstand α mit den Metallen b und c in bekannter Weise einem hohen Flüssigkeitsdruck unterworfen wird, was ein festes Gegeneinanderpressen der Metalle zur Folge hat. Ohne den in dem Behälter vorhandenen Druck zu verringern, wird gemäß der Erfindung die Druckflüssigkeit von der Feuerung/ aus erhitzt, wobei sich die homogene Verbindung der Metalle miteinander vollzieht. Der Grad der Erhitzung der Druckflüssigkeit richtet sich nach dem Schmelzpunkt der zur Verbindung gelangenden Metalle. Die. Beheizung der Druckflüssigkeit könnte selbstverständlich auch durch irgendeine andere beliebige Wärmequelle erfolgen.The trap is deepened, is laid out with the correspondingly shaped metals b and c , whereby of course the metal surfaces in contact must be metallically pure, and then placed in the container d . Pressure fluid is then pumped into the container by means of the pump e , so that the object α with the metals b and c is subjected in a known manner to a high fluid pressure, which results in the metals being pressed firmly against one another. Without reducing the pressure present in the container, according to the invention the pressure fluid is heated from the furnace / from, the homogeneous connection of the metals to one another taking place. The degree of heating of the hydraulic fluid depends on the melting point of the metals to be joined. The. The pressure fluid could of course also be heated by any other desired heat source.
