Description

Hilfsmittel für die spanlose und spanabhebende Metallverformung Die Erfindung b:efaßt sich mit einem Hilfsmittel für die spanlose und :spanabhebende Metallverformung als Schmiermittel, wie z. B. in Form von Ölen, die als Schneid-, Bohr- und Getriebeöle Anwendung von Mineralölen, die zur Metallverspanung oder oder auch zur Erleichterung der Gleitung beim Ziehen. bzw. Pressen und zur Erlangung eines einwandfreien Laufs von aufeinandergleitenden Flächen benutzt werden.Tools for non-cutting and metal-cutting metal deformation Invention b: includes an aid for non-cutting and: cutting Metal deformation as a lubricant, such as. B. in the form of oils, which are used as cutting, Drilling and gear oils Application of mineral oils that are used for machining metal or or also to facilitate sliding when pulling. or pressing and for obtaining smooth running of surfaces sliding on top of each other.

In der Regel erfolgt eine sogenannte Veredlung von Mineralölen, die zu Meztallverspanung oder auch als Schmiermittel in Lagern bzw. 'Getrieben Anwendung finden, durch einen Zusatz von Schwefel oder auch von Graphit. Die Größe der Schwebeteilchen in dem Öl ist verhältnismäßig klein gewählt und beträgt im allgemeinen i bis 5o ,u. Es ist aber auch schon bekannt, zur Veredlung von Schmierölen polymere Kohlenwas@sers;toffe, wie z. B. Isobutylen, Styrol u. a. zu verwenden. Durch den Zusatz derartiger Stoffe gelingt es, die Gleiteigenschaften des Öls wesentlich zu verbessern.As a rule, there is a so-called refinement of mineral oils, the for metal cutting or as a lubricant in bearings or gearboxes by adding sulfur or graphite. The size of the suspended particles in the oil is selected to be relatively small and is generally from 1 to 50 , u. However, it is already known to refine lubricating oils with polymeric hydrocarbons, such as B. isobutylene, styrene and others. to use. By adding such substances succeeds in significantly improving the sliding properties of the oil.

Es ist ferner nicht mehr neu, zur Herstellung fester Gele von organischen Lösungsmitteln auszugehen und diesen Polyamide zuzusetzen, die in der Lage sind, als gelierendes Agenz wirksam zu werden. Die Polyamide sind in diesen Gelen vollkommen gelösit. Es hat sich jedoch gezeigt, daß derartige Gele nicht allen Anforderungen, die an ein veredeltes Mineralöl gestellt werden, gerecht werden können, weil .offenbar keine ausreichende Sicherheit für die Aufrechterhaltung des Schmierölfilms gewährleistet ist.Furthermore, it is no longer new for making solid gels from organic To go out of solvents and to add polyamides to these, which are able to to act as a gelling agent. The polyamides are perfect in these gels solved. However, it has been shown that such gels do not meet the requirements the at one refined mineral oil are provided because. evidently insufficient security to maintain the Lubricating oil film is guaranteed.

Erfindungsgemäß besteht das Hilfsmittel für die sparlose und ispanabheberde Metallverformung aus einem Mineralöl mit einem Gehalt von i bis 5 Gewichtsprozent, bezogen auf das Mineralöl, an Schwebeteilchen aus Superpolyamiden, mit einer Teilchengröße von i bis 2 ,u.According to the invention, the aid consists of the economical and ispanic lifting soil Metal deformation from a mineral oil with a content of 1 to 5 percent by weight, based on the mineral oil, on suspended particles made of super polyamides, with a particle size from i to 2, u.

Kunststoffen haftet an sich bekanntlich der Nachteil an, daß ihre Verwendung für Gegenstände, die sich durch gute Gleiteigenschaften auszeichnen müssen, kaum in Frage kommt. Die Kunststoffe besitzen nämlich eine sehr kleine Wärmeleiitfälligkeit, so @daß die Gefahr besteht, daß die Kunst; s,toffe beim Erlangen einer bestimmten Temperatur die für die Gleitbewegung erforderliche mechanische Festigkeit verlieren. Obgleich die Superpolyamide hervorragende Gleiteigenschaften aufweisen, hat dieser Mangel !eine weitgehende Verwendung als Gleitflächen für den vorerwähnten Zweck stark beeimlträchtigt. Es ist zwar versucht worden, die Lauf-bzw. Gleitschichten aus derartigen Kunststoffen hinreichend dünn zu machen; es hat sich jedoch herausgestellt, daß hierdurch die Lebensdauer sehr stark eingeschränkt wird. Werden jedoch Superpolyamide entsprechend der erfindungsgemäßen Hilfsmittel für die sparlose und sparabbehende Metallverformung als Schwebeteilchen in Mineralölen verwendet, verleihen sie denselben eine hervorragende Fähigkeit, einwandfreie Schmierfilmschichten zu bilden und einen solchen Schmierfilm auch dauernd aufrechtzuerhalten. Die Polyamidteilchen schließen, nämlich den aufgerissenen Film immer wieder sofort oder bilden ihn neu. Die Superpolyamidtenlchen sind ferner dank ihrer Kleinheit im der Lage, im Öl schweben zu bleiben und setzen auch nicht vorzeitig ab. Darüber hinaus vermögen 'sie auch in alle Lagerspalten einzuL dringen.As is known, plastics have the disadvantage that their Use for objects that have to be characterized by good sliding properties, is hardly an option. The plastics have a very low thermal conductivity, so @ that there is a danger that art; s, toffe in attaining a certain Temperature lose the mechanical strength required for sliding movement. Although the super polyamides have excellent sliding properties, this one has Deficiency! Extensive use as sliding surfaces for the aforementioned purpose heavily impaired. It has been tried to run or. Sliding layers to make sufficiently thin from such plastics; however, it turned out that this severely limits the service life. However, super polyamides are used corresponding to the aids according to the invention for the sparless and sparabbehende Metal deformation used as suspended particles in mineral oils, they impart the same an excellent ability to form flawless layers of lubricating film and one to maintain such a lubricating film permanently. The polyamide particles close namely the torn film again and again immediately or form it anew. The super polyamide bags thanks to their small size are also able to float and settle in the oil also not prematurely. In addition, they can also be used in all camp gaps to penetrate.
