Description

Ziehschmiermittel Zum Ziehen von Me Stalldrähten verwendet man Ziehschmiermittel oder Ziehbadflüssigkeiten. Beispielsweise erfolgt das Ziehen verkupferter Stahldrähte, das in großem Umfange unter anderem bei der Herstellung von. Sprungfedern Anwendung findet, aus betrieblichen und Qualitätsgründen in der Weise, daß der im schwefelsauren Kupfersulfat verkupferte Stahldraht ohne vorherige Entfernung der Säure durch das Ziehbad geführt wird. Die auf dem Markt befindlichen zum Teil roggenmehlha,ltigen Ziehschmiermittel auf der Grundlage tierischer Fette bilden in saurem Medium keine beständige Emulsion, so daß ein gleichmäßiger Drahtzug nicht gewährleistet ist; sie brechen schon nach kurzer Benutzungsdauer unter der Einwirkung der in das Bad eingeschleppten Schwefelsäure.Drawing lubricant Drawing lubricants are used to pull Me stable wires or draw bath fluids. For example, copper-plated steel wires are drawn, this to a large extent, among other things, in the production of. Coil springs application finds, for operational and quality reasons, in such a way that the sulfuric acid Copper sulfate copper-plated steel wire without prior removal of the acid by the Drawing bath is performed. Some of the rye flour that is on the market Drawing lubricants based on animal fats do not form in an acidic medium permanent emulsion, so that an even wire tension is not guaranteed; they break after a short period of use under the action of the bathroom introduced sulfuric acid.

Es bestand mithin die Aufgabe:, ein Ziehschmiermittel zu schaffen, das in beliebigen Konzentrationen eine homogene stabile Emulsion in Wasser bildet, und die weitere: Aufgabe, Emulsionen herzustellen, die sich selbst höherkonzentrierten Säuren gegenüber genügend stabil verhalten und nicht bei Einwirkung von Säure schnell zerfallen.The task was therefore: to create a drawing lubricant, which forms a homogeneous stable emulsion in water in any concentration, and the other: the task of producing emulsions that are more highly concentrated Behave sufficiently stable to acids and not quickly when exposed to acids disintegrate.

Gemäß der Erfindung wird ass Ziehschmiermittel eine wäßrige Emulsion, aus einem oder mehreren tierischen Fetten wie Rinder- oder Hammeltalg mit einem Gehalt an aliphatischen Polyglykolestern aus 2 bis 10 Mol Äthylenoxyd und Fettsäuren mit 12 bis 18 C-Atomen verwendet. Die Polyglykolester umfassen vorzugsweise Ester, die aus Laurin-, Stearin-, Ölsäure und 2 bis 10 Mol Äthylenoxy d hergestellt sind.According to the invention, the drawing lubricant is an aqueous emulsion, from one or more animal fats such as beef or mutton tallow with one Content of aliphatic polyglycol esters from 2 to 10 moles of ethylene oxide and fatty acids with 12 to 18 carbon atoms used. The polyglycol esters preferably include esters, which are made from lauric, stearic, oleic acid and 2 to 10 moles of ethyleneoxy d.

Die Emulsion kann außerdem weitere bekannte Bestandteile, wie aliphatische Polyglykolä,ther und bzw. oder Partia.lester des Glyzerins mit gesättigten Fettsäuren von, 12 bis 18 C-Atomen, vorzugsweise Stearinsäure, ferner stabilisierende Zusätze auf der Basis von Zellulose, Methylzellulose enthalten.The emulsion can also contain other known ingredients, such as aliphatic Polyglycol ether and / or Partia.lester of glycerine with saturated fatty acids of .12 to 18 carbon atoms, preferably stearic acid, and also stabilizing additives based on cellulose, contain methyl cellulose.

Der Gehalt des Ziehschmiermittels an Emulgatoren beträgt etwa 1 bis 10, vorzugsweise etwa 2 bis 4 Gewichtsprozent, bezogen auf die Gesamtmischung. Etwa vorhandene Stabilisatoren wie Methylzellulose bilden 1 bis 5 Gewichtsprozent des Ziehschmiermittels.The emulsifier content of the drawing lubricant is about 1 to 10, preferably about 2 to 4 percent by weight, based on the total mixture. Approximately existing stabilizers such as methyl cellulose form 1 to 5 percent by weight of the Drawing lubricant.

Alipha,tische Polyglykolester sind. an sich als Mittel zum Emulgieren verschiedener Stoffe bekannt. Die Erfindung liegt in der Verwendung dieser Stoffe als Emulgatoren für Ziehschmiermittelemulsione-n, die auch gegenüber häherkonzentrierten Säuren beständig sind.Aliphatic polyglycol esters are. per se as an emulsifying agent various substances known. The invention resides in the use of these substances as emulsifiers for drawing lubricant emulsions, which are also more concentrated Acids are resistant.

Das Ziehen verkupferter Stahldrähte, das in Deutschland in großem Umfang unter andrem bei der Herstellung von Sprungfedern aller Art An-«-endung findet, erfolgt aus be:triebdichen und Qualitätsgründen nach zwei Verfahren. A. Der in bekannter Weise geheizte, gewaschene, gebonderte und gekälkte Walzdraht wird vorgezogen und nach Passieren eines schwefelsauren Verkupferungsbades anschließend ummittelbar in da: Bad eines Naßzi@ehschmiermittels geführt; B. der vorgezogene Draht wird aus einem saurer Verkupferungsba,d, welches das Naßziehschmiermittel bereits enthält, gezogen Alle Ziehschmiermittel, die nicht hochsäurefessind, versagen naturgemäß bei dem Verfahren B welches vorsieht, daß das Ziehschmiermittel sieh irr schwefelsauren Verkupferungsbad selbst befindet Aber auch beim anschließenden Passieren des ge kupferten Drahtes durch das Ziehschmiermittel wir( dieses in kurzer Zeit gebrochen oder aufgerahmt, weii die Ziehschmiermittel durch die eingeschlepp,tw Schwefelsäure zersetzt werden.The drawing of copper-plated steel wires, which in Germany in large Scope is used, among other things, in the manufacture of all types of coil springs, takes place for operational and quality reasons according to two procedures. A. The well-known Wise heated, washed, bonded and limed wire rod is preferred and after passing through a sulfuric acid copper plating bath then immediately in there: bath of a wet lubricant carried out; B. the drawn wire is turned off an acidic copper plating, d, which already contains the wet drawing lubricant, drawn All drawing lubricants that are not highly acid-proof naturally fail in method B, which provides that the drawing lubricant is sulfuric acid However, the copper plating bath itself is also located during the subsequent passage of the ge copper wire through the drawing lubricant we (this broken in a short time or framed, white the drawing lubricant by the entrained, tw sulfuric acid be decomposed.

Zu beachten ist, daß bei dem Verfahren A der in schwefelsauren Kupfersulfatbad verkupferte Stahl drah,t ohne vorherige Entfernung der Säure durch da Ziehbad geführt wird. Eine Wasserwäsche des ver kupferteni Stahldrahtes vor Einführung in das Zieh bad wird von den Betrieben aus verschiedenen Grün den z. B. wegen zusätzlicher Raumbeanspruchung uni zeitlicher Belastung abgelehnt.It should be noted that in process A, the copper sulphate bath in sulfuric acid Copper-plated steel wire, t passed through the drawing bath without first removing the acid will. A water wash of the copper-plated steel wire before insertion into the drawer bad is the z. B. because of additional space requirements uni time burden rejected.

Die Herstellung des Ziehschmiermittels erfolgt vorteilhaft durch Zusammenrühren der Bestandteile" zweckmäßig unter Erwärmen auf 70 bis 100° C.The drawing lubricant is advantageously produced by stirring together the components "expediently by heating to 70 to 100 ° C.

Bei der Erprobung wurde eine 10°/oige wäßrige Emulsion eines Ziehschmiermittels gemäß Erfindung selbst nach Hinzufügen von konzentrierter Schwefelsäure bis zur Endkonzentration von etwa 20% Schwefelsäure nicht zersetzt.In the test, a 10% aqueous emulsion of a drawing lubricant was used according to the invention even after adding concentrated sulfuric acid to Final concentration of about 20% sulfuric acid not decomposed.

Das säurebeständige Ziehschmiermittel läßt sich rasch schon in kaltem Wasser zu einer wäßrigen Emulsion von sahneartigem Aussehen emulgieren. Dieses neue Produkt unterscheidet sieh von den bekannten Ziehschmiermitteln durch die völlige Homogenität der Emulsion, die dadurch einen ganz gleichmäßigen Drahtzug gewährleistet. Das. Ziehschmiermittel gemäß der Erfindung eignet sich auch zum Tiefziehen von Blechen z. B. im Kanisterbau.The acid-resistant drawing lubricant can be quickly poured into cold Emulsify water to form an aqueous emulsion with a creamy appearance. This new one The product differs from the known drawing lubricants in that it is complete Homogeneity of the emulsion, which guarantees a very even wire tension. That. Drawing lubricant according to the invention is also suitable for deep drawing sheet metal z. B. in canister construction.
