Description

Die Erfindung betrifft ein Verfahren zur elektrolytischen Metallummantelung von Aluminiumdraht und eine Vorrichtung zur Durchführung dieses Verfahrens. Metallisch ummantelter Aluminiumdraht, insbesondere verzinnter Aluminiumdraht, ist in erster Linie für die Verwendung ' * der Elektroindustrie bestimmt da Lötverbindungen zwischen Leitern auf Aluminiumbasis ohne eine metallische Ummantelung des Drahtes schwierig oder gar nicht hergestellt werden können. Metallisch ummantelter Aluminiunidraht schützt diesen auch gegen Angriffe von Säuren, die sich bei der Ummantelung mit Gummi oder Kunststoff bilden.The invention relates to a Ver f Ahren for the electrolytic metal coating of aluminum wire and an apparatus for performing this method. Metallically sheathed aluminum wire, in particular tinned aluminum wire, is primarily intended for use in the electrical industry, since soldered connections between conductors based on aluminum are difficult or impossible to make without a metallic sheathing of the wire. Metallically sheathed aluminum wire also protects it against attack by acids that are formed when sheathing with rubber or plastic.

Da die sofortige Oxydation der Oberfläche des Aluminiumdrahtes bei dessen Herstellung das Aufbringen metallischer Ummantelungen sehr schwierig macht hat man bereits vorgeschlagen, die Drahtoberfläche auf elektrochemischem Weg zunächst mit einer, allerdings lehr dünnen, Zinkschicht zu versehen, auf die dann die Metallummantelungen in üblicher Weise elektrolytisch aufgebracht wurden. Dies Verfahren und die damit erzielten Erzeugnisse konnten sich, insbesondere wegen der Empfindlichkeit der äußerst dünnen Zinkzwischenichicht, in der praktischen Anwendung nicht durchsetzen. Because the immediate oxidation of the surface of the aluminum wire during its manufacture is the application Making metallic sheaths very difficult, it has already been proposed to put the wire surface on electrochemically to initially provide an, albeit very thin, zinc layer on which the Metal sheaths were applied electrolytically in the usual way. This procedure and the one with it obtained products could, in particular because of the sensitivity of the extremely thin zinc interlayer, do not prevail in practical application.

Die Erfindung hat sich die Aufgabe gestellt, eine unempfindliche, dauerhafte Verbindung zwischen Metallmantel und Aluminiumdraht-Oberfläche herzustellen. Die Aufgabe wird dadurch gelöst, daß der entfettete und dekapierte Draht in einer sich unmittelbar unter Luftabschluß an die Beizstufe anschließenden Ziehstufe ein oder mehrere elektrolytische Metallumraantelungsbäder durchläuft Dem Ummantelungsbad kann, wie die Erfindung weiter vorsieht eine weitere Ziehstufe zur Oberflächenverdichtung der aufgebrachten Metallummantelung nachgeschaltet werden und in einer Vorrichtung zur Durchführung dieses Verfahrens soll erfindungsgemäß das Dekapierbad von dem ersten elektrolytischen Metallummantelungsbad und von den nachfolgenden Bädern durch Ziehsteine getrennt werden. Die Ziehsteine können dabei die Kathoden des Metallum-The invention has the task of providing an insensitive, permanent connection between the metal jacket and manufacture aluminum wire surface. The object is achieved in that the degreased and pickled wire in a drawing step immediately following the pickling step in the absence of air one or more metal jacketed electrolytic baths The coating bath can, as the invention further provides, a further drawing stage for Surface compaction of the applied metal cladding can be connected downstream and in a device in order to carry out this method, according to the invention, the pickling bath should be separated from the first electrolytic bath Metal coating bath and be separated from the subsequent baths by drawing dies. the The drawing dies can remove the cathodes of the metal

i) mantelungsbades bilden. An diese Bäder folgen in bekannter Weise Kalt- und Warmspülbäder mit Passivierung. Das Verfahren läßt die Behandlung mit einem Strang im Umkehrverfahren oder mit mehreren Strängen im Geradeausverfahren zu.i) form a coating bath. These baths follow in known way cold and warm rinsing baths with passivation. The procedure leaves the treatment with one strand in the reverse process or with several strands in the straight-ahead process.

Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeispiels erläutert:The invention is explained using the exemplary embodiment shown in the drawing:

Der Draht 1 wird zunächst vom Abstreifstrahl einer Luftdüse 15 beaufschlagt und gelangt dann in das Entfettungsbad 2. In diesem sind Oberlaufwände 8 und Anoden 11 angeordnet Die Entfettungslösung wird von dem Sammelbehälter 17 mittels der Pumpe 16 in das Bad 2 gepumpt und läuft mit freiem Gefälle wieder zum Sammelbehälter 17 zurück. Der Draht verläßt dann das Entfettungsbad 2 und gelangt durch die Trennwand 20 unter den Abstreifstrahl der Luftdüse 21 über die Oberlaufwand 22 -n das Dekapierungsbad 3. Am Ende dies.es Bades ist eine Trennwand 23 mit einem Ziehstein IO angeordnet Die Anoden des elektrolytisch arbeitenden Dekapierungsbades sind mit 12 bezeichnet DieThe wire 1 is first acted upon by the wiping jet of an air nozzle 15 and then enters the Degreasing bath 2. In this upper flow walls 8 and anodes 11 are arranged. The degreasing solution is from the collecting tank 17 is pumped into the bath 2 by means of the pump 16 and runs with a free gradient back to Collection container 17 back. The wire then leaves that Degreasing bath 2 and passes through the partition 20 under the wiping jet of the air nozzle 21 via the Upper wall 22 -n the pickling bath 3. At the end of this bath there is a partition 23 with a drawing die IO arranged The anodes of the electrolytically working pickling bath are denoted by 12 Die

J5 Dekapierungslösung gelangt vom Sammelbehälter 18 über eine Pumpe 24 in das Bad und läuft dann in den Sammelbehälter 18 zurück. Durch den Ziehstein 10 gelangt der Draht ohne mit Luftsauerstoff in Berührung gelangt zu sein, durch die Trennwand 23 in das Metallummantelungsbad 4 und v.rläßt dieses durch einen in der Trennwand 25 angeordneten Ziehstein 26. Das Metallummantelungsbad 4 ist mit Anoden 13 ausgestattet und wird über die Pumpe 27 analog wie die vorhergehenden Bäder mit dem Sammelbehälter 19 verbunden. Die Ziehsteine 10 und 26 dienen bei diesem Ausführungsbeispiel gleichzeitig als Kathoden im Metallummantelungsbad 4.J5 pickling solution comes from collecting container 18 into the bath via a pump 24 and then runs back into the collecting container 18. Through the die 10 the wire passes through the partition 23 into the without having come into contact with atmospheric oxygen Metal sheathing bath 4 and v. Leaves this through a drawing die 26 arranged in the partition 25. The metal cladding bath 4 is equipped with anodes 13 and is operated via the pump 27 in an analogous manner to that previous baths connected to the collecting container 19. The drawing dies 10 and 26 are used in this Exemplary embodiment simultaneously as cathodes in the metal-clad bath 4.

Der fertig ummantelte und oberflächenverdichtete Aluminiumdraht gelangt umgelenkt durch die Rollen 14The completely sheathed and surface-compacted aluminum wire is deflected and passed through the rollers 14

so jn das Kaltspülbad 5, das Warmspülbad 6 und anschließend in das Passivierungsbad 7, von wo er weiteren Bearbeitungsstufen zugeführt werden kann.so jn the cold rinsing bath 5, the warm rinsing bath 6 and then into the passivation bath 7, from where it can be fed to further processing stages.
