Description

Der Erfindung liegt die Aufgabe zugrunde, ein-oder mehradrige elektrische Leitungen, die eine Aderisolierung aus Gummi oder gummiartigen Stoffen und einen zusätzlichen gemeinsamen Außenmantel aus gleichartigem Stoff besitzen, in einer einzigen Vorrichtung herstellen zu können. Gemäß der Erfindung besitzt eine zur Herstellung derartiger Leitungen dienende Vorrichtung in Form einer Strangpresse zwei gleichachsig ineinander angeordnete Förderschnecken, von denen die innere auf ein Mundstück zur Herstellung der Aderisolierhüllen und die äußere auf ein weiteres Mundstück zur Herstellung des Außenmantels arbeitet. The invention is based on the object of single-core or multi-core electrical Cables that have a core insulation made of rubber or rubber-like materials and a have additional common outer jacket made of the same material, in one to be able to produce a single device. According to the invention has a for Manufacture of such lines serving device in the form of an extrusion press two coaxially arranged screw conveyors, of which the inner one is on a mouthpiece for the production of the core insulation and the outer one on another Mouthpiece for the production of the outer jacket works.

Handelt es sich dabei um die Herstellung mehradriger Leitungen, so wird für das erste Mundstück ein Mehrfachmundstück verwendet, in dem gleichzeitig nebeneinander mehrere parallel geführte Leiter umhüllt werden können. If it concerns the production of multi-core cables, so a multiple mouthpiece is used for the first mouthpiece, while at the same time several parallel conductors can be wrapped next to each other.

Falls die Leitung mehrere Gummihüllen, also beispielsweise über der Isolierung einen mehrfachen Außenmantel besitzen sqll, ist es ohne weiteres möglich, im Sinn der Erfindung mehrere gleichachsige Förderschnecken ineinander anzuordnen. If the line has several rubber sleeves, for example over the Insulation have a multiple outer sheath sqll, it is easily possible in the sense of the invention to arrange several coaxial screw conveyors one inside the other.

In der Zeichnung ist ein Ausführungsheispiel einer Vorrichtung gemäß der Erfindung dargestellt. In the drawing, an embodiment of a device is according to of the invention shown.

Diese Vorrichtung besitzt gemäß der Erfindung in dem Gehäuse I eine innere Förderschnecke 2 und eine äußere Förderschnecke 3, die durch einen Zwischenmantel 4 voneinander getrennt sind. Die innere Förderschnecke 2, auf die der Werkstoff durch den Fülltrichter 5 aufgeliefert wird, arbeitet auf ein Mundstück 6, durch das die Aderisolierung hergestellt wird, während die äußere Förderschnecke 3, zu der der Fülltrichter 7 gehört, auf ein hinter dem Mundstück 6 angeordnetes weiteres Mundstück 8 arbeitet, durch das der Außenmantel der Leitung hergestellt wird.This device has according to the invention in the housing I a inner screw conveyor 2 and an outer screw conveyor 3, through an intermediate jacket 4 are separated from each other. The inner screw conveyor 2, on which the material is delivered through the hopper 5, works on a mouthpiece 6, through that the core insulation is made while the outer screw conveyor 3, too to which the hopper 7 belongs to a further arranged behind the mouthpiece 6 Mouthpiece 8 works, through which the outer jacket of the line is made.

Falls die Vorrichtung zur Herstellung einer einadrigen Leitung dienen soll, kann der Leiter in üblicher Weise durch eine Mittelbohrung der Schnecke 2 zu dem Mundstück 6 geführt werden. If the device is used to produce a single-core cable should, the conductor can in the usual way through a central hole in the worm 2 be guided to the mouthpiece 6.

Handelt es sich aber um eine Vorrichtung zur Herstellung mehradriger Leitungen, also beispielsweise wie bei dem dargestellten Ausführungsbeispiel um die Herstellung zweiadriger Leitungen, können die Leiter g durch entsprechende Bohrungen in dem Zwischenmantel 4 zu dem ersten Mundstück 6 geleitet werden. Die Mundstücke erhalten, wie bei dem dargestellten Ausführungsbeispiel gezeigt, zweckmäßig, um eine sichere zentrische Führung der Leiter zu gewährleisten, unmittelbar vor der Mündung eingebaute, gegen die Außenwandung durch Rippen abgestützte Führungen ii bzw. 12 für die Leiter. -Der Antrieb der beiden Schnecken; erfolgt vorzugsweise durch einen gemeinsamen Motor, jedoch über zwei regelbare Getriebe, um die Fördergeschwindigkeit der beiden Schnecken einzeln regeln und dadurch einander anpassen zu können.But if it is a device for the production of multi-core Lines, for example as in the illustrated embodiment the production of two-core cables, the conductor g can through appropriate holes are passed in the intermediate jacket 4 to the first mouthpiece 6. The mouthpieces obtained, as shown in the illustrated embodiment, expedient to to ensure a safe central guidance of the ladder, immediately in front of the Muzzle built-in guides supported against the outer wall by ribs ii or 12 for the ladder. -The drive of the two screws; preferably takes place by a common motor, but via two adjustable gears to increase the conveyor speed to regulate the two screws individually and thus to be able to adapt to each other.
