Description

Verfahren zur Kaltformgebung von Metallen . Zusatz zum [email protected] 921044 In dem Patent 92,1 o4.4. ist ein Verfahren zur Kaltformgebung von Metallen unter Schutz gestellt, das darin besteht, daß als Kühl- und Schmiermittel wäßrige Lösungen wasserlöslicher Schmiermittel mit Zusätzen von kolloidalem Schwefel verwendet werden. Dem kolloidalen Schwefel kommt dabei die Aufgabe zu, im Ziehvorgang, also im wesentlichen im Bereich des Ziehwerkzeugs, einen die Kaltformgebung erleichternden Sulfidfilm zu erzeugen. Die Bildung dieses Sulfidfilms wird durch die bei der Formgebung auftretende Erwärmung des Ziehgutes und des Ziehwerkzeugs erheblich beschleunigt.Process for the cold forming of metals. Addition to [email protected] 921 044 In the patent 92.1 o4.4. a process for the cold forming of metals is placed under protection, which consists in the fact that aqueous solutions of water-soluble lubricants with additions of colloidal sulfur are used as coolants and lubricants. The task of colloidal sulfur is to produce a sulfide film that facilitates cold forming in the drawing process, i.e. essentially in the area of the drawing tool. The formation of this sulphide film is considerably accelerated by the heating of the drawn material and the drawing tool during shaping.

Als wasserlösliche Schmiermittel wurden Fettalkoholsulfonate und Seifen verwendet. Es wurde nun gefunden, daß man an Stelle dieser wasserlöslichen Schmiermittel auch wäßrige Emulsionen von Schmierölen verwenden kann. Während bei dem in der deutschen Patentschrift 74.7 4.22 vorbeschriebenen Verfahren die Verwendung von Elektrolyte, wie Ammoniumsulfiden, als Sulfidbildner sich nachteilig auf die Beständigkeit der Emulsionen auswirkt, übt kolloidaler Schwefel keine entmischende Wirkung auf die wäßrigen Emulsionen von Schmierölen aus.Fatty alcohol sulfonates and soaps have been used as water-soluble lubricants used. It has now been found that instead of these water-soluble lubricants can also use aqueous emulsions of lubricating oils. While in the German Patent 74.7 4.22 the above-described method the use of electrolytes, such as ammonium sulfides, as sulfide formers have a detrimental effect on the stability of the Emulsions, colloidal sulfur does not have a segregating effect on the aqueous emulsions made from lubricating oils.

Obwohl kolloidaler Schwefel gegen Elektrolyte weniger empfindlich ist als die meisten anderen Kolloide, bietet die Verwendung elektrolytfreier oder -armer wäßriger Emulsionen von Schmierölen an Stelle der wäßrigen Lösungen von Fettalkohol-und anderen Sulfonaten den Vorteil, daß auch bei längerem Gebrauch der erfindungsgemäßen sulfidierenden Schmiermittel keine die Reaktionsfähigkeit vermindernde Ausflockung des kolloidalem Schwefels eintritt.Although colloidal sulfur is less sensitive to electrolytes than most other colloids, the use of electrolyte-free or offers -lower aqueous emulsions of lubricating oils instead of aqueous solutions of fatty alcohol and others Sulphonates have the advantage that even with prolonged use of the sulphidating according to the invention Lubricant does not reduce the reactivity of the colloidal flocculation Sulfur enters.

Die Gehalte an kolloidalem Schwefel in den erfindungsgemäßen Schmiermitteln richten; sich nach der Reaktionsfähigkeit der kalt zu verformenden Metalle mit kolloidalem Schwefel und nach den angewandten, die Temperaturverhältnisse im Ziehwerkzeug bestimmenden Verformungsgraden. Kohlenstoffarme Stähle gestatten die Anwendung geringerer Schwefelgehalte.-Gegen die Einwirkung des kolloidalen Schwefels resistentere Stähle bedingen die Anwendung höherer Gehalte an kolloidalem Schwefel.The contents of colloidal sulfur in the lubricants according to the invention judge; depending on the reactivity of the cold-formed metals with colloidal Sulfur and according to the applied, determining the temperature conditions in the drawing tool Deformation degrees. Low-carbon steels allow the use of lower sulfur contents the action of the colloidal sulfur more resistant steels require the application higher levels of colloidal sulfur.

Ein für Stähle mit einem Kohlenstoffgehalt bis zu 0,25°/o geeignetes Schmiermittel kann beispielsweise aus g.o Gewichtsteilen eines üblichen Bohrölkonzentrats, 3o bis q.o Gewichtsteilen Wasser und 3o bis 2o Gewichtsteilen einer wäßrigen Lösung oder Suspension kolloidalen Schwefels bestehen, dessen Reingehalt an Schwefel 5o bis 6o% beträgt.One suitable for steels with a carbon content up to 0.25% Lubricant can, for example, consist of g.o parts by weight of a conventional drilling oil concentrate, 3o to q.o parts by weight of water and 3o to 2o parts by weight of an aqueous solution or suspension of colloidal sulfur, the purity of which is 5o up to 6o%.
