Description

"Ölfreies Schmiermittel" In der Praxis wird häufig nach Ziehvorgängen ein Weich- bzw. Zwischenglühen oder auch eine Blsktroschweißung durohgeführ', Die üblichen Schmiermittel, eie für derartige Kaltverformun-7': gen verwendet werden, enthalten im allgemeinen erhebliche Mengen an Fetten und Ölen sowie sonstigen organischen Bestandteilen. Durch die erwähnte Beharidl'ting tritt leicht die Bildung von Ölkohle oder starke Rauchentwicklung auf.. Auch bereitet es häufig Schwierigkeiten, die Reste= des Schmiermittels durch eine einfache Reinigung zu entfernen."Oil-free lubricant" is often used in practice after drawing operations a soft or intermediate annealing or a blow welding durohführ ', Die common lubricants, which are used for such cold forming, generally contain significant amounts of fats and oils and other organic substances Components. By the behavior mentioned above, the formation of oil carbon occurs easily or heavy smoke development .. It also often causes difficulties Remnants = of the lubricant can be removed by simple cleaning.

1 a Es wurde nun gefunden, daß man derartige Mängel weitgehend vermeiden kann, wenn man sich der nachstehend beschriebenen ölfreien Schmiermittel für die Kaltverformung bedient. Diese bestehen aus polymeren Alkaliphoaphaten sowie Borax und Borsäure in einer Menge von 40 bis 65 % (Beet Wasser), bezogoti auf die Gesamtkomposition. Als polymere Phosphate kommen insbesondere Kalium und bevor- ' zogt Natrium-, Hexameta- bzw. Tripolyphosphat in Frage. Eine rt vdrzugsweise Ausführungsform besteht darin, daß Gemische von Alkalihexametaphosphat und Alkalitripolyphosphat verwendet werden. Der Anteil dieser Komponenten beträgt jeweils 5 bis 20, vorzugsweise 10 bis 15 %, bezogen auf die Gesamtkomposition.1 a It has now been found that such deficiencies can largely be avoided if the oil-free lubricants described below are used for cold forming. These consist of polymeric alkali phosphates as well as borax and boric acid in an amount of 40 to 65 % (bed water), based on the total composition. Particularly suitable polymeric phosphates are potassium and preferably sodium, hexameta or tripolyphosphate. In a preferred embodiment, mixtures of alkali hexametaphosphate and alkali tripolyphosphate are used. The proportion of these components is in each case 5 to 20, preferably 10 to 15%, based on the total composition.

Die weiteren Bestandteile, Borax und Borsäure, finden jeweils in Mengen von 7 bis 18 %, vorzugsweise 10 bis 15 %, Anwendung. Die Wassermenge der erfindungsgemäßen Mittel schwankt zwischen 4.0 bis 65 % und ist im allgemeinen hinreichend, um die Beetandteile zu lösen. Dies wird vorzugsweise unter leichter Erwärmung vorgenommen. In manchen Fällen hat es sich als vorteilhaft erwiesen, wenn die öben beschriebenen ölfreien Schmiermittel für die Kaltverformung noch einen weiteren Zusatz von Pigmenten, wie Kreide, Talkum, Graphit oder Molybdändisulfid, vorzugsweise Glimmer und/oder feinverteilte Kieselsäure bzw. Kieselkreide, wie Neuburger Kreide, enthalten. Die Gesamtmenge dieses Zusatzes kann wichen 5 und 10 % liegen. Je nach der Art des zu verformenden Materials ist es in manchen Fällen vorteilhaft, eine geringe Menge an sich bekannter Netzmittel dem ölfreien Schmiermittel zuzusetzen. Der Zusatz beträgt etwa 0,3 bis 2, vorzugsweise 0,5 bis 1 %, bezogen aifdie desamtkomposition. Die Zufügung von Pigmenten sowie gegebenenfalls Netzmitteln zu dem ölfreien Schmiermittel erfolgt zweckmäßigerweise, nachdem die übrigen anorganischen Bestandteile in Wasser gelöst sind.The other constituents, borax and boric acid, are each used in amounts of 7 to 18%, preferably 10 to 15%. The amount of water in the agents according to the invention varies between 4.0 and 65% and is generally sufficient to dissolve the constituent parts. This is preferably done with slight heating. In some cases it has proven to be advantageous if the above-described oil-free lubricants for cold forming have a further addition of pigments, such as chalk, talc, graphite or molybdenum disulfide, preferably mica and / or finely divided silica or silica chalk, such as Neuburg chalk, contain. The total amount of this additive can vary between 5 and 10%. Depending on the type of material to be deformed, it is advantageous in some cases to add a small amount of known wetting agents to the oil-free lubricant. The addition is about 0.3 to 2, preferably 0.5 to 1%, based on the total composition. Pigments and optionally wetting agents are expediently added to the oil-free lubricant after the other inorganic constituents have been dissolved in water.

Es ist selbstverständlich möglich, gewUnschtenfalls, insbesondere bei sehr leichten Zügen, die beschriebenen Mittel noch weiter mit Wasser zu verdünnen, wobei insbesondere bis zu 4, vorzugsweise 1 bis 2, Teile Wasser auf ein Teil ölfreies Schmiermittel in Betracht kommen.It is of course possible, if desired, in particular in the case of very light draws, dilute the agents described further with water, in particular up to 4, preferably 1 to 2, parts of water to one part of oil-free Lubricants come into consideration.

Die genannten Mittel haben im übrigen den Vorteil, daß sie sich gewünschtenfalls nach dem Ziehvorgang durch einfache Wasserspülung mühelos entfernen lassen. Man kann jedoch auch, insbesondere bei Lagerung der Materialien, die Reste des Ölfreien Schmiermittels auf der Metalloberfläche belassen und erhält auf diese Weise gleichzeitig einen guten Rostschutz. Beispiel 1: Durch Auflösen von 15 Teilen Natriumhexametaphosphat 15 Teilen Natriumtripolyphosphat 15 Teilen Borax sowie 15 Teilen Borsäure in 40 Teilen Wasser unter leichtem Erwärmen wurde ein ölfreies Schmiermittel hergestellt. 3 mm starkes Blech, welches mit diesem Mittel behandelt wurde, ließ sich einwandfrei zu Schüsseln kalt verformen. Das Schmiermittel konnte nach der Kaltverformung durch einfaches Spülen mit Wasser entfernt werden. Beispiel 2: Bei einem ähnlichen Ziehprozeß wie im Beispiel--1, wobei jedoch das Blech nicht völlig entfettet war, wurde als Schmiermittel eine Lösung verwendet, die 15 % Natriumhexametaphosphat 15 % Natriumtripolyphosphat 15 % Borax 15 % Borsäure 0,5 % Netzmittel 39,5 % Wasser enthielt. Die Kaltverformung ließ sch einwandfrei.' durch- führen. Die anschließend mehrere.,Tage gelagerten Teile blieben rostfrei und die Schmierrrittelreste ließen sleh auch danach leicht entfernen. S-eispiel 3 Zur Kaltverformung von 1 mm dicken Blechen wurde ein Schmiermittel verwendet, welches 13 % Natriumhexametaphosphat 13 % Natriumtripolyphosphat 10 % Borax 10 % Borsäure 0,5 % Netzmittel 10: Glimmer 43$5 % Wasser enthielt. Zur Herstellung desselben wurden die genannten ersten 4 Bestandteile unter Erwärmen in Wasser gelöst. Dann wurden das Netzmittel und das Pigment in Form von tilner zugefügt und gut vermischt. Das so erhaltene SchmiermIttel wurde vor der Anwendung mit je 1 Teil Wasser pro An-teil Schmiermittel verdünnt. Die an den Blechen vorgenomme-nen leichten Züge ließen sich einwandfrei durchführen. Das 3phmiermittel@konnte dureh Abspülen mit Wasser jeweils leicht tforgt werdon.The above-mentioned agents also have the advantage that, if desired, they can be easily removed by simply rinsing with water after the drawing process. However, it is also possible, especially when storing the materials, to leave the residues of the oil-free lubricant on the metal surface and at the same time obtain good rust protection in this way. Example 1: An oil-free lubricant was prepared by dissolving 15 parts of sodium hexametaphosphate, 15 parts of sodium tripolyphosphate, 15 parts of borax and 15 parts of boric acid in 40 parts of water with gentle heating. 3 mm thick sheet metal that was treated with this agent could be perfectly cold-formed into bowls. After cold forming, the lubricant could be removed by simply rinsing with water. Example 2: With a similar drawing process as in the example - 1, where however the sheet metal was not completely degreased when Lubricant uses a solution that 15% sodium hexametaphosphate 15% sodium tripolyphosphate 15% borax 15% boric acid 0.5 % wetting agent 39.5% water contained. The cold deformation was perfect. ' by- to lead. The parts then stored for several days remained rust-free and the smudges left sleh easily remove afterwards as well. Example 3 A lubricant was used for cold forming 1 mm thick sheets which contained 13% sodium hexametaphosphate 13% sodium tripolyphosphate 10% borax 10% boric acid 0.5% wetting agent 10 : mica 43% 5% water . To produce the same, the first 4 constituents mentioned were dissolved in water with heating. Then the wetting agent and the pigment in the form of tilner were added and mixed well. The lubricant obtained in this way was diluted with 1 part of water per part of lubricant before use. The light pulls made on the sheets could be carried out without any problems. The lubricant @ could easily be removed by rinsing with water.
