Description

Herstellung von Aluminiummänteln elektrischer Kabel mit einer Schneckenpresse Neben den mit periodisch auf und: ab, oder hin und her bewegten Kolben und Stempeln arbeitenden Pressen zur Herstellung von nahtlosem: Mänteln für elektrische Kabel sind bekanntlich auch Maschinen entwickelt worden, die das Preßmetall fortlaufend mittels. einer Schnecke auspressen. Das Preßmetall wird diesen Schnecken in. flüssigem Zustand zugeführt und erstarrt während des Vorschubes, zum Mundstück. Die Entwicklung dieser meist als Umpreßmaschinen bezeichneten Kabelmantelpressen ist so weit gekommen, daß diese Maschinen mit Erfolg bereits in verschiedenen Werken zur Herstellung von, Bleimänteln benutzt werden. Aluminium erfordert nach den seit einiger zeit vorhandenen Erkenntnissen einen erheblich höheren Preßdruck als Blei, wenn es zu nahtlosen Kabelmänteln verarbeitet werden: soll. Die Fachwelt hat deshalb bisher davon abgesehen:, die mit einer Schnecke arbeitenden Umpreßmaschinen zur Herstellung von Aluminiummänteln zu benutzen:. Es sind vie-lm..-hr hierfür ausschließlich Kolbenpressen eingesetzt worden.Manufacture of aluminum sheaths of electrical cables with a screw press In addition to the pistons and pistons that are periodically moved up and down, or to and fro working presses for the production of seamless: sheaths for electrical cables As is well known, machines have also been developed which continuously press the pressed metal by means of. squeeze out of a snail. The pressed metal is liquid in these screws State supplied and solidified during the advance towards the mouthpiece. The development this cable jacketing press, usually referred to as a crimping machine, has come so far that these machines have already been successfully used in various plants for the production of, Lead jackets are used. Aluminum requires after those that have existed for some time Findings a considerably higher pressing pressure than lead when it comes to seamless cable jackets processed: should. The professional world has therefore so far refrained from: who Pressing machines working with a screw for the production of aluminum jackets to use:. Much ..- your only piston presses are used for this been.

Die Erfindung besteht nun darin., den: mit einer Schnecke arbeitenden Umpreßmaschinen Aluminium in der Form, wie es bei seiner Darstellung aus. niedrigschmelzenden Elektrolyten aus Aluminiumehlorid und' Alkalichlorid anfällt, der Schnecke zuzuführen und in ihr unter Wärmezufuhr beim Vorschub der Presse unter Verschweißung oder Vers.interung zu einem nahtlosen; Mantel zu formen.The invention now consists in the: working with a screw Umpreßmaschinen aluminum in the form as it is made when it is presented. low melting point Electrolytes from aluminum chloride and 'alkali chloride accumulates, the snail to feed and in it with the supply of heat when the press is advanced under welding or sintering into a seamless; Shaping coat.

Es ist zwar nicht für Schneckenpressen, sondern für Kolbenpressen: schon: bekannt, dem Aufnehmer der Presse das Preßmetall, u. a. auch Aluminium, nicht in flüssiger Form oder ganzen Bolzen, sondern kleinstückig zuzuführen. und; in Form eines Stranges auszupressen. Demgegenüber nutzt die Erfindung zwar auch die Tatsache aus, daß die Verschweißung oder Versinterung von Reinstaluminium, etwa vom Reinheitsgrad 99,99°/Q, unter Druck schon bei mäßigen Temperaturen so gut gelingt, da.ß nachträglich keine Nähte mehr zu erkennen sind. Jedoch besteht der grundsätzliche Vorzug und technische Fortschritt des Verfahrens gemäß der Erfindung darin, daß es die Verarbeitung von Reinstaluminium in der Form gestattet, wie es bei der Darstellung des Aluminiums aus niedri.gschmelzenden Elektrolyten aus Aluminiumchlo,rid und Alkalichlorid anfällt. Bisher bestand nämlich die Notwendigkeit, das bei diesem. Verfahren. in kleinen Stücken entstehende Aluminium erst zusammenzuschmelzen, um es weiter verarbeiten zu können, wobei die infolge der feinen Verteilung des Aluminiums großem, Oxydinengen erheblich störten. Falls gewünscht, kann das entstehende Aluminium bei Ausführung der Erfindung ohne Berührung mit der Außenluft aus dem Elektrolysebad in. die Schneckenpresse gebracht werden, nämlich entweder mittels geschlossener und unter Umständen sogar mit einem Schutzgas gefüllter oder evakuierter Behälter oder schließlich auch mittels geschlossener Förderanlagen (Förderbänder od. dgl.), falls die Elektrolyseanlage neben oder wenigstens in der Nähe der Kabe@lmantelpresse aufgestellt ist. Da die zur Durchführung der Erfindung erforderlichen Drücke höher liegen:, als sie bisher bei der Verarbeitung von Blei in Schneckenpressen auftraten, empfiehlt es sich,- die Pressen entsprechend kräftiger zu. bauen. Es lassen sich mit Vorteil aber auch solche bereits vorgeschlagenen Pressen verwenden, bei denen eine massive vorzugsweise stehende Schnecke auf das senkrecht zu ihr durch die Presse hindurchgeführte Kabel einen Mantel aufpreßt. Man kann ferner auch Mehrfachpressen; mit mehreren, und insbesondere gegenläufig zusammenarbeitenden Schnecken verwenden, wie solche, bisher zur Verarbeitung von besonders zähem: organischen. Kunststoffen verwendet woirden sind. Schließlich können auch Doppelpressen verwendet werden, bei denen zwei oder mehr Schnecken im schrägen Winkel zur Pressemhauptachse angeordnet sind (sogenannte Vau-Maschinen), die bisher ebenfalls nur zur Verarbeitung von organischen Kunststoffen Verwendlwng gefunden haben.True, it's not for screw presses, but for piston presses: already: known, the press metal, among other things. even aluminum, no in liquid form or whole bolts, but in small pieces. and; in shape to squeeze out a strand. In contrast, the invention also makes use of the fact from the fact that the welding or sintering of pure aluminum, for example of the degree of purity 99.99 ° / Q, works so well under pressure even at moderate temperatures that afterwards no more seams can be seen. However, the basic advantage is and technical progress of the method according to the invention in that it is processing of pure aluminum in the form as it is in the representation of aluminum from low-melting electrolytes made of aluminum chloride and alkali chloride. So far there has been a need to do this with this one. Procedure. in small First melt pieces of resulting aluminum together in order to process it further to be able to, whereby the large, Oxydinengen due to the fine distribution of the aluminum significantly bothered. If desired, the resulting aluminum can be used during execution of the invention without contact with the outside air from the electrolysis bath in. the screw press be brought, namely either by means of closed and under certain circumstances even with a protective gas filled or evacuated container or finally by means of closed conveyor systems (conveyor belts or the like), if the electrolysis system is set up next to or at least in the vicinity of the cable jacketing press. Since the pressures required to carry out the invention are higher than they were previously occurred during the processing of lead in screw presses, it is recommended - the presses close accordingly. build. But it can also be used to advantage use such previously proposed presses where a massive one is preferred standing screw on the cable passed through the press perpendicular to it pressing on a coat. Multiple presses can also be used; with several, and in particular Use opposing co-operating screws, such as those previously used for processing of particularly tough: organic. Plastics are used. In the end Double presses can also be used with two or more screws in the are arranged at an inclined angle to the main axis of the press (so-called Vau machines), which up to now has also only been used for processing organic plastics have found.
