Description

Verfahren und Vorrichtung zum Umkleiden stabförmiger Körper mit Kunststoffen Die Erfindung hat sich die Aufgabe gestellt, stab förmige Körper, insbesondere elektrische Leiter, wie beispielsweise Sammelschienen od. dgl., mit einer porenfreien Isolierung aus härtbaren oder thermoplastischen Kunststoffen zu versehen.Method and device for cladding rod-shaped bodies with plastics The invention has the task of rod-shaped body, especially electrical Conductors, such as busbars or the like, with pore-free insulation to be provided from curable or thermoplastic plastics.

Es ist bekannt, Körper mit rotationssymmetrischen Hohlräumen aus härtbaren Kunstharzmassen im Schleudergußverfahren herzustellen. It is known to make bodies with rotationally symmetrical cavities to produce curable synthetic resin compositions in a centrifugal casting process.

Hierbei wurden den Kunstharzmassen Füll- bzw.Here, the synthetic resin masses were filled or

Streckmittel auch in Form von Textilgeweben, Drahtnetzen oder ähnlichen flächigen Gebilden zugesetzt. Ferner ist es bekannt, Stangen, Rohre, Schläuche u. dgl. aus Kunststoff im Schleudergußverfahren herzustellen, bei dem die gießfähige Kunststoffschmelze von einer mit einer zentralen Eingießöffnung versehenen Drehscheibe aus in strahlenförmig auseinanderstrebende Formrohre geschleudert wird.Extenders also in the form of textile fabrics, wire nets or the like added to flat structures. It is also known that rods, tubes, hoses and. Like. Manufacture of plastic by centrifugal casting, in which the castable Plastic melt from a turntable with a central pouring opening is hurled into radiating divergent shaped tubes.

Gemäß der Erfindung erfolgt die Umkleidung der stabförmigen Körper mit Kunststoffen im Schleudergußverfahren. Es wird eine Schleudergußvorrichtung verwendet, die am Umfang einer Trommel gleichmäßig verteilt, parallel zur Trommelachse, die gleichzeitig Rotationsachse ist, Vertiefungen zur Aufnahme der zu umgießenden stabförmigen Körper aufweist. According to the invention, the rod-shaped bodies are clad with plastics in the centrifugal casting process. It becomes a centrifugal casting machine used, which are evenly distributed on the circumference of a drum, parallel to the drum axis, which is also the axis of rotation, recesses for receiving the to be encapsulated Has rod-shaped body.

Hierbei sind Größe und Querschnittsform der Vertiefungen der herzustellenden Kunststoffisolierung entsprechend ausgebildet. Die zu umgießenden stabförmigen Körper, die in den Vertiefungen der Schleudergußeinrichtung angeordnet sind, können auch eine zusätzliche Rotation um ihre eigene Achse ausführen. Hierdurch wird es möglich, beispielsweise Leiter, die vorher mit faserförmigen Stoffen, z. B.The size and cross-sectional shape of the depressions are the ones to be produced Plastic insulation designed accordingly. The rod-shaped bodies to be cast around, which are arranged in the depressions of the centrifugal casting device can also perform an additional rotation around its own axis. This makes it possible for example, conductors previously covered with fibrous materials, e.g. B.

Glasseide, umsponnen sind, mit einer guten Durchtränkung mit dem Kunststoff zu versehen. Das erfindungsgemäße Verfahren hat den großen Vorteil, daß es möglich ist, eine porenfreie Isolierung herzustellen, da die Lufteinschlüsse während des Schleuderverfahrens sich in Richtung auf die Drehachse der Schleudergußeinrichtung bewegen und austreten.Glass silk, wound with a good impregnation with the plastic to provide. The method according to the invention has the great advantage that it is possible is to produce a pore-free insulation, since the air inclusions during the Centrifugal process in the direction of the axis of rotation of the centrifugal casting device move and step out.

In den F i g. 1 und 2 ist die Erfindung schematisch an einem Beispiel erläutert. In the F i g. 1 and 2 is the invention schematically using an example explained.

Die Schleudergußeinrichtung 1, die um die Drehachse 2 umläuft, weist an ihrem Umfang verteilt Vertiefungen 3, 4, 5 und 6 auf, in welche die zu umgießenden stabförmigen Körper 7, 8, 9 und 10 eingesetzt sind. In die Schleudergußeinrichtung wird eine Kunststoffmenge eingebracht, die zur Ausfüllung der Vertiefungen 3 bis 6 eben ausreicht und durch Rotation der gesamten Einrichtung in diese Vertiefungen befördert wird. Hierbei werden die bei der Rotation auftretenden Beschleunigungskräfte die eingeschlossenen Luftblasen in Richtung auf die Rotationsachse 2 aus dem Material herausbefördern, so daß man eine porenfreie Isolierung erhält. The centrifugal casting device 1, which revolves around the axis of rotation 2, has on its periphery distributed depressions 3, 4, 5 and 6, in which the to be cast Rod-shaped bodies 7, 8, 9 and 10 are used. In the centrifugal casting facility a quantity of plastic is introduced, which is necessary to fill the depressions 3 to 6 is sufficient and by rotating the entire device in these wells is promoted. The acceleration forces that occur during the rotation are used here the enclosed air bubbles in the direction of the axis of rotation 2 from the material convey out, so that a pore-free insulation is obtained.

Das erfindungsgemäße Verfahren eignet sich sowohl für thermoplastische als auch für duroplastische Kunststoffe, die gefüllt oder ungefüllt Verwendung finden können. The inventive method is suitable for both thermoplastic as well as for thermosetting plastics, which are used filled or unfilled can.

Gemäß der weiteren Erfindung können die stabförmigen Körper, z. B. elektrischen Leiter, vorher mit faserförmigen Stoffen, z.B. Glasseide, umsponnen werden, wobei zur guten Durchtränkung dieser Umspinnung die zu umgießenden Körper 7 bis 10 eine zusätzliche Rotation um ihre eigene Achse erhalten. According to the further invention, the rod-shaped body, for. B. electrical conductor, previously wrapped with fibrous material, e.g. glass silk be, with the body to be cast around for a good saturation of this wrapping 7 to 10 are given an additional rotation around their own axis.
