Bekanntlich erfordert das Strangpressen von Metallen und Legierungen mittels der hydraulischen Presse bei einer unterhalb ihres Schmelzpunktes liegenden Temperatur die Verwendung von besonderen Schmiermitteln zum Schutz des Werkzeuges und zur Erleichterung des Gleitens des Werkstoffes an den Wänden der Teile, welche die Aufgabe haben, bei dem Strangpreß Vorgang die gewünschte Form zu erteilen.It is known that the extrusion of metals and alloys by means of the hydraulic If the temperature is below their melting point, press the use of special ones Lubricants to protect the tool and to facilitate the sliding of the material on the walls of the parts which the Have the task of giving the desired shape during the extrusion process.

Bis jetzt vermeiden die verschiedenen vorgeschlagenen Schmierverfahren nicht in befriedigender Weise die von der Verschlechterung des Werkzeuges herrührenden Ausreißungen, die Bildung von Rissen oder den Einschluß von schädlichen Teilen im Rohling. Die letzteren fördern, indem sie die Ursache zur Heterogenität bilden, insbesondere das Entstehen von Korrosionserscheinungen.So far, the various proposed lubrication methods have not been avoided in a more satisfactory manner Avoid the tears resulting from the deterioration of the tool, the formation of cracks or the inclusion of harmful parts in the blank. Promote the latter by causing the cause to form heterogeneity, in particular the emergence of corrosion phenomena.

Die Erfindung gestattet es, diese Bildung von Rissen und die schädlichen Einschlüsse auf der Oberfläche des Rohlings zu vermeiden; außerdem ao bietet sie den Vorteil, das Werkzeug, die Düse, den Stempel, den Dorn usw. in gutem Zustand zu erhalten, und sie erlaubt eine Erhöhung der Strangpressengeschwindigkeit. The invention allows this formation of cracks and the harmful inclusions on the Avoid surface of the blank; In addition, it offers the advantage that the tool, the nozzle, the Maintain the punch, mandrel, etc. in good condition and allow the extrusion speed to be increased.

Gegenstand der Erfindung ist ein Schmiermittel as für Werkzeuge von Metallstrangpfessen, bestehend aus einem natürlichen oder synthetischen Fettprodukt, dem ein Metallpulver einverleibt ist, und ist dadurch gekennzeichnet, daß das fein verteilte und innig mit dem Fettprodukt vermischte Metallpulver von gleicher Natur wie das zu pressende Metall ist.The invention relates to a lubricant as for tools of metal pegs, consisting of a natural or synthetic fat product, to which a metal powder is incorporated, and is characterized in that the finely divided and metal powder, intimately mixed with the fat product, of the same nature as that to be pressed Metal is.

Es ist bereits vorgeschlagen worden, als Schmiermittel ein Fettprodukt zu verwenden, welchesIt has already been proposed to use a fat product as a lubricant, which

Metallpulver enthält; aber dessen Natur war, da es hauptsächlich .wegen seiner Geschmeidigkeit ausgewählt wurde, von derjenigen des bearbeiteten Metalles verschieden, was die Ursache späterer Korrosionen war. Die Erfindung hilft diesem Mangel ab.Contains metal powder; but its nature was chosen mainly for its suppleness became different from that of the worked metal, which is the cause later Corrosion was. The invention remedies this deficiency.

Das Schmiermittel kann irgendein natürliches oder synthetisches Schmiermittel sein; im besonderen wird ein mineralisch-pflanzliches oder ein synthetisches Wachs mit hohem Schmelzpunkt empfohlen.The lubricant can be any natural or synthetic lubricant; in particular A mineral-vegetable or synthetic wax with a high melting point is recommended.

Unter dem zu pressenden Metall ist entweder ein reines Metall oder eine Legierung zu verstehen; das erfindungsgemäß in dem Schmiermittel zu verwendende Metallpulver ist dasselbe Metall wie das ζιϊ pressende Metall oder eine Legierung, .welche als Grundmetall den gewichtsmäßigen Hauptbestandteil der zu pressenden Legierung enthält.The metal to be pressed is either a pure metal or an alloy; the According to the invention to be used in the lubricant metal powder is the same metal as the ζιϊ pressing metal or an alloy, which is the main constituent by weight as the base metal the alloy to be pressed.

Der als Träger für das Metallpulver dienende Schmierstoff wird zweckmäßigerweise nach den Arbeitsbedingungen, der Arbeitstemperatur und der Anwendungsart des Gemisches ausgewählt.Serving as a carrier for the metal powder lubricant is expediently according to the Working conditions, the working temperature and the type of application of the mixture selected.

Der Mengenanteil des Metallpulvers hängt von denselben Bedingungen ab, ist aber stets höher als 5 Gewichtsprozent. Nach einem einfachen Ausführungsbeispiel kann man beim Strangpressen von röhrenförmigen Rohlingen aus einer leichten Aluminiumlegierung ein Gemisch verwenden, welches % von unfühlbar feinem Aluminiumpulyer in einem mineralischen Wachs von hohem Schmelzpunkt enthält; die Arbeit geht ohne Hängenbleiben vor sich; die Außen- und Innenflächen der Rohre sind vollständig glatt.The proportion of the metal powder depends on the same conditions, but is always higher than 5 percent by weight. According to a simple embodiment, you can extrude tubular blanks made of a light aluminum alloy use a mixture which % of imperceptibly fine aluminum powder in contains a mineral wax of high melting point; the work goes without getting stuck in front of you; the outer and inner surfaces of the tubes are completely smooth.
