Verfahren und Vorrichtung zur elektrolytischen Metallummantelung von Aluminiumdraht Method and device for the electrolytic Metallumman teling of aluminum wire

Die Erfindung betrifft ein Verfahren zur elektrolytischen Metallummantelung von Aluminiumdraht und eine Vorrichtung zur Durchführung dieses Verfahrens.The invention relates to a method for the electrolytic metal coating of aluminum wire and a device to carry out this procedure.

Metallisch ummantelter Aluminiumdraht, insbesondere verzinnter Aluminiumdraht, ist in erster Linie für die Verwendung in der Elektroindustrie bestimmt, da Lötverbindungen zwischen Leitern auf Aluminiumbasis ohne eine metallische Ummantelung des Drahtes schwierig oder gar nicht hergestellt werden können. Metallisch ummantelter Aluminiumdraht schützt diesen auch gegen Angriffe von Säuren, die sich bei der Ummantelung mit Gummi oder Kunststoff bilden.Metallic sheathed aluminum wire, particularly tinned aluminum wire, is primarily for use Determined in the electrical industry because soldered connections between conductors are based on aluminum without a metallic sheathing of the wire are difficult or impossible to produce. Metallic coated aluminum wire protects this also against attacks by acids that are present in the coating form 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 Draht oberfläche auf elektrochemischem Weg zu-nächst mit einer, allerdings sehr 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 Zinkzwischenschicht, in der praktischen Anwendung nicht durchsetzen.Because the immediate oxidation of the surface of the aluminum wire in the production of which makes the application of metallic coatings very difficult, it has already been proposed that the wire surface first of all by electrochemical means to be provided with a very thin zinc layer, on which the metal sheaths in the usual way Way were electrolytically applied. This process and the products obtained with it could, in particular because of the sensitivity of the extremely thin zinc intermediate layer, do not prevail in practical use.

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 einerThe invention has set itself the task of creating an insensitive, permanent connection between the metal jacket and the aluminum wire surface to manufacture.

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 Metallummantelungsbades 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.immediately after the pickling stage in the absence of air. Drawing stage passes through one or more electrolytic metal coating baths. The jacketed bath can, as the invention further provides, a further drawing stage for surface compression of the applied metal cladding are connected downstream and in a device for performing this method, according to the invention Pickling bath from the first electrolytic metal jacketing bath and from the subsequent baths through drawing dies be separated. The drawing dies can form the cathodes of the metal coating bath. Follow these baths in a known manner, cold and warm rinsing baths with passivation. The process leaves the single-strand treatment in reverse or with multiple strands in a straight line 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 Überlaufwände 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 überlaufwand in das Dekapierungsbad 3. Am Ende dieses Bades ist eine 'Trennwand 23 mit einem Ziehstein 10 angeordnet. Die Anoden des elektrolytisch arbeitenden Dekapierungsbades sind mit 12 bezeichnet. Die Dekapierungslösung gelangt vom Sammelbehälter 18 über eine Pumpe 23 in das Bad und läuft dann in den Sammelbehälter l8 zurück. Durch den Ziehstein 10 gelangt der Draht, ohne mit Luftsauerstoff in Berührung gelangt zu sein, durch die Trennwand 23 in das Metallummantelungsbad 1I und verläßt dieses durch einen in der Trennwand 25 angeordneten Ziehstein 26. Das Metallummantelungsbad 1J ist mit Anoden 13 ausgestattet und wird über die Pumpe 26 analog wie die vorhergehenden Bäder mit dem Sammelbehälter 19 verbunden. Die Ziehsteine 10 und dienen bei diesem Ausführungsbeispiel gleichzeitig als Kathoden im Metallummantelungsbad 1I.The wire 1 is first acted upon by the wiping jet from an air nozzle 15 and then passes into the degreasing bath 2. In this overflow walls 8 and anodes 11 are arranged. The degreasing solution is pumped from the collecting container 17 by means of the pump 16 into the bath 2 and runs back to the collecting container 17 with a free gradient. The wire then leaves the degreasing bath 2 and passes through the partition 20 under the wiping jet of the air nozzle 21 over the overflow wall into the pickling bath 3. A partition 23 with a drawing die 10 is arranged at the end of this bath. The anodes of the electrolytically working pickling bath are denoted by 12. The pickling solution passes from the collecting container 18 via a pump 23 into the bath and then runs back into the collecting container 18. Through the die 10, the wire passes, without being engaged with atmospheric oxygen into contact, by the partition wall 23 in the Metallummantelungsbad 1 I and leaves it is a arranged in the partition wall 25 drawing die 26. The Metallummantelungsbad 1 J is provided with anodes 13 and Connected to the collecting container 19 via the pump 26 in a manner analogous to the preceding baths. The dies 10 and serve at the same time in this embodiment as the cathode in Metallummantelungsbad 1 I.
