"Verfahren zum Schmieren eines metallischen Werkstoffs für dessen Bearbeitung und Schmiermittel zur Durchführung des Verfahrens""Method of lubricating a metallic material for its processing and lubricants for carrying out the process "

Das Bearbeiten von Metallen, wie walzen, schmieden, warmpressen, stanzen, biegen, prägen, ziehen, schneiden, lochen und drücken auf der Drehbank erfordert im allgemeinen ein Schmiermittel. Dieses erleichtert solche Arbeitsgänge dadurch, daß es beispielsweise den erforderlichen Kraftaufwand verringert, eine zu große Haftung vermeidet und die Abnutzung von Stanzwerkzeugen und Schneidbacken reduziert. Zusätzlich verleiht das Schmiermittel dem zu bearbeitenden Metall korrosionsverhindernde Eigenschaften. Bei der üblichen Arbeitsweise wird das Metall nach seiner Bearbeitung verschiedenen chemischen Behandlungen unterworfen, beispielsweise mit Lösungen beschichtet, weshalb zwischen dem Bearbeiten des Metalls und der chemischen Behandlung ein Reinigungsvorgang nötig ist. Deshalb soll das Schmiermittel neben den oben genannten Eigenschaften auch die Möglichkeit bieten, daß es durch Anwendung üblicher Reinigungsmittel leicht von der Metalloberfläche entfernt werden kann.The processing of metals, such as rolling, forging, hot pressing, Punching, bending, embossing, drawing, cutting, punching and pressing on the lathe generally requires a lubricant. This facilitates such operations by, for example, reducing the effort required, avoids excessive adhesion and the wear and tear of punching tools and cutting jaws reduced. In addition, the lubricant gives the metal to be machined corrosion-preventing properties Properties. In the usual way of working, the metal becomes different chemical after it has been worked Subjected to treatments, e.g. coated with solutions, therefore, a cleaning process is necessary between the machining of the metal and the chemical treatment. That's why the lubricant should also offer the possibility, in addition to the properties mentioned above, that it can be used more commonly Cleaning agent can be easily removed from the metal surface.

Bisher waren Schmiermittel für die vorgenannten Zwecke Flüssigkeiten. Die Vorrichtung zum Auftragen solcher Flüssigkeiten sind oft teuer im Betrieb und unbequem einzusetzen. Auch ist im allgemeinen ein Trockenofen erforderlich, um aus dem Schmiermittel als Träger wirkendes Wasser oder Lösungsmittel zu entfernen, wodurch weitere erhebliche Kosten für Investiti-. onen und für die Verwendung solcher Schmiermittel anfallen. Darüber hinaus treten oft Schwierigkeiten in automatischen Vorrichtungen zur Beschickung mit zu bearbeitenden Metallteilen oder in anderen die Metallteile fördernden Vorrichtungen auf, da die flüssigen Schmiermittel, die im allgemeinen auf die Metallteile aufgetragen sind, diese naß und rutschig machen und deshalb die Handhabung der Metallteile erschweren.So far, lubricants for the aforementioned purposes have been liquids. The devices for applying such liquids are often expensive to operate and inconvenient to use. Also is Generally a drying oven is required to remove water or solvent from the lubricant as a carrier remove, thereby creating further significant investment costs. onen and arise for the use of such lubricants.

However, this film can only be partially are present on the surface.

Der physikalische Zustand des Schmiermittels während des Auftragens auf die Metalloberfläche ist nicht kritisch. Beim erfindungsgemäßen Verfahren kann das Schmiermittel als Feststoff, z.B. durch Reiben, oder als Flüssigkeit, z.B. durch Bürsten, Sprühen, Tauchen, Gießen, Walzen oder Gegenv/alzen, aufgetragen werden. Vorzugsweise wird das Schmiermittel im flüssigen Zustand aufgetragen, wonach es durch Abkühlen verfestigt wird. Das Schmiermittel kann auch während der Bearbeitung des Werkstückes diesem direkt zugeführt werden.The physical state of the lubricant during application on the metal surface is not critical. When the invention Process the lubricant as a solid, e.g., by rubbing, or as a liquid, e.g., by Brushing, spraying, dipping, pouring, rolling or counter-rolling, can be applied. Preferably, the lubricant is im liquid state, after which it is solidified by cooling. The lubricant can also be used during machining of the workpiece are fed directly to it.

Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens und der erfindungsgemäßen Schmiermittel liegt darin, daß sich die flüssig aufgetragenen Schmiermittel zu einem festen,nicht— blockenden und nicht schlüpfrigen Film auf der Metalloberfläche verfestigen, wodurch die Werkstücke gut zu handhaben sind und Kosten gespart werden.

Umgebungstemperatur bis nahe an der Zersetzungstemperatur des Schmiermittels liegen. Diese Temperatur hängt von der Art der Behandlung des metallischen Werkstücks vor oder nach dem Auftragendes Schmiermittels, dem Schmelzpunkt des Schmiermittels und dessen Temperatur im Zeitpunkt des Auftragens ab. Besonders geeignet sind Oberflächentemperaturen des Metalls von etwa 20 bis 125°C. Zum Zeitpunkt des Auftragens des Schmiermittels soll die Temperatur des Schmiermittels höher liegen als sein Schmelzpunkt, vorzugsweise um mindestens 100C, insbesondere um etwa 20 bis 4O0C, damit dieses leicht fließt und sich gleichmäßig auf der Metalloberfläche verteilt.Ambient temperature close to the decomposition temperature of the lubricant. This temperature depends on the type of treatment of the metal workpiece before or after the application of the lubricant, the melting point of the lubricant and its temperature at the time of application. Surface temperatures of the metal of about 20 to 125 ° C. are particularly suitable. At the time of applying the lubricant, the temperature of the lubricant should be higher than its melting point, preferably by at least 10 0 C, particularly about 20 to 4O 0 C, so that this flows easily and uniformly distributed on the metal surface.

Das geschmolzene Schmiermittel kann auf die Metalloberfläche bei einem Minimum an erforderlichem Raum aufgetragen v/erden, wobei schon vorhandene Vorrichtungen, wie in Stahlwerken verwendete Wickelvorrichtungen, verwendet werden können. Da das flüssig aufgebrachte Schmiermittel sich bei Umgebungstemperatur rasch verfestigt und trocken, nichtblockend und nicht schlüpfrig wird, können auch andere übliche Vorrichtungen zur Handhabung der Werkstücke, wie Transportwaizen, eingesetzt werden. Die erfindungsgemäß behandelten Werkstücke können auch mit Staplern transportiert werden. Ein weiterer besonderer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß es im Gegensatz zu bekannten Verfahren keinen Trockenofen benötigt, da aus den erfindungsgemäßen Schmiermitteln kein Wasser oder Lösungsmittel abzutrennen ist.The molten lubricant can be applied to the metal surface with a minimum of space required, existing devices, such as winding devices used in steelworks, can be used. Since that Liquid applied lubricants solidify rapidly at ambient temperature and are dry, non-blocking and non-blocking If it becomes slippery, other conventional devices for handling the workpieces, such as transport wheels, can also be used will. The workpieces treated according to the invention can also be transported with forklifts. Another special one The advantage of the method according to the invention is that that, in contrast to known methods, there is no need for a drying oven, since the lubricants according to the invention do not contain any Separate water or solvent.
