Description
Die Erfindung bezieht sich auf eine Vorrichtung, um elektrische Leiter mit Faserflorstreifen aus Asbest zu isolieren. Die Vor-. richtung besitzt in an sich bekannter Weise einen umlaufenden Glätter, der radial zum Leiter wirkt und die Einhüllung des mit Klebstoff versehenen Leiters in den in der Längsrichtung des Leiters herangeführten Faserflor vornimmt. Derartige Vorrichtungen sind druckschriftlich verschiedentlich bekanntgeworden. Bei diesen Vorrichtungen ist nur eine geringe Einflußnahme auf die Güte der Einhüllung und Isolation vorhanden.The invention relates to a device for making electrical conductors to be insulated with asbestos fiber pile strips. The pre. direction owns in on As is known, a circumferential smoother that acts radially to the conductor and the wrapping of the adhesive-coated conductor in the longitudinal direction the fiber pile brought up by the head. Such devices are in print has become known variously. With these devices there is only a small one Influence on the quality of the envelope and insulation available.
Erfindungsgemäß sind deshalb vor dem Glätter. in einer dessen Antriebsscheibe tragenden Hohlspindel ein oder mehrere Spinnippel angeordnet, die eine vollkommen gleichmäßige Vorverdichtung des Faserflors vornehmen und damit den Glätter vor stets gleiche Spinnaufgaben stellen, wodurch auch das Produkt gleichmäßig wird. Damit eine Anpassung an verschiedene Drahtstärken und verschiedene Isolationszugaben oder -dicken möglich ist, sind die Spinnippel auswechselbar, so daß die dem jeweiligen Drahtquerschnitt und der Isolation entsprechenden Spinnippeldurchmesser gewählt werden können. Außerdem sind die Glätterkeile des Glätters in ihrem Abstand radial gegeneinander einstellbar.According to the invention are therefore before the smoother. in one of its drive pulleys bearing hollow spindle one or more spinning nipples arranged, the one perfectly Carry out even pre-compression of the fiber web and thus the smoother always in front set the same spinning tasks, which means that the product is also uniform. In order to an adaptation to different wire thicknesses and different insulation allowances or -thickness is possible, the spinning nipples are interchangeable, so that the respective Wire cross-section and the spinning nipple diameter corresponding to the insulation selected can be. In addition, the trowel wedges of the trowel are radial in their spacing adjustable against each other.
Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.The invention is shown in an exemplary embodiment in the drawing.
Fig. i zeigt den. Spinner im Längsschnitt; Fig. 2 ist eine Draufsicht auf die mit dem Vorglätter versehene Ausgangsseite.Fig. I shows the. Spinner in longitudinal section; Fig. 2 is a plan view on the exit side provided with the pre-straightener.
DerSpinner besteht aus einemLagerbock i, in dem in Kugellagern 3 eine Hohlachse 2 gelagert ist. Auf dieser Achse ist zum Antrieb mittels Schrauben 5 o. dgl. eine Keilscheibe .I aufgesetzt. Auf der Eingangsseite der Achsel ist auswechselbar eine Spinndüse 6 befestigt. Sie wird nach außen durch eine Schutzscheibe 7 abgeschlossen, die den Zutritt loser Asbestwolle zu den Kugellagern verhindert. In der Achse 2 sind, ebenfalls auswechselbar, z. B. zwei weitere Spinndüsen 8 und 9 vorgesehen, deren Bohrungen stufenweise kleiner werden. Von diesen wird die Düse 8 durch Anschrauben der Düse 9 mittels der Schrauben. io festgehalten. Hinter den Düsen befindet sich der Glätter. Dieser kann besonderen Antrieb erhalten. Zweckmäßig wird er direkt an der Keilscheibe-1 befestigt. Er besteht aus zwei Winkeln 12, die durch Längsschlitz 13 und Schraube 14 in den an der Keilscheibe q. befestigten Führungen i i radial eingestellt werden können. Die Winkel 12 tragen überFedern 15 zwei ineinanderpassende Keilstücke 16 und 17, zwischen denen die Vorglättung des besponnenen Leiters erfolgt. Zusätzlich oder an Stelle der Federn 15 können auch Schraubenfedern 18 benutzt werden. Die Verbindung zwischen den Federn und den Keilstücken 16 und 17 ist lösbar, um auch hier die Teile leicht auswechseln zu können.The spinner consists of a bearing block i in which a hollow axle 2 is mounted in ball bearings 3. A wedge disk .I is placed on this axis for the drive by means of screws 5 or the like. A spinneret 6 is replaceably attached to the inlet side of the armpit. It is closed off from the outside by a protective disk 7, which prevents loose asbestos wool from entering the ball bearings. In the axis 2 are also interchangeable, for. B. two further spinnerets 8 and 9 are provided, the bores of which are gradually smaller. Of these, the nozzle 8 is screwed on the nozzle 9 by means of the screws. held io. The straightener is located behind the nozzles. This can receive a special drive. It is expediently attached directly to the wedge disk-1. It consists of two angles 12, which are fixed by a longitudinal slot 13 and screw 14 in the on the wedge disk q. attached guides ii can be adjusted radially. The angles 12 carry two wedge pieces 16 and 17 which fit into one another via springs 15, between which the pre-smoothing of the spun conductor takes place. In addition to or instead of the springs 15, coil springs 18 can also be used. The connection between the springs and the wedge pieces 16 and 17 can be released so that the parts can also be easily replaced here.
Im allgemeinen genügt es, wenn die Abfederung nur an einem Keilstück, z. B. dem Stück 16, vorgenommen wird, während das andere Keilstück 17, zwar auswechselbar, jedoch starr mit dem Winkel 12 verbunden ist.In general, it is sufficient if the cushioning is only on a wedge, z. B. the piece 16 is made, while the other wedge 17, although replaceable, however, it is rigidly connected to the angle 12.
Die Vorrichtung arbeitet in der Weise. daß der Glätter bei seinem Umlauf den mit Klebstoff versebenen Leiter in die Faserflorschicht. in deren Längsrichtung der Leiter eingeführt ist, einwickelt.The device works in that way. that the smoother at his Wrap the conductor, which has been leveled with adhesive, into the fiber pile layer. in their longitudinal direction the conductor is inserted, wraps.
Die Spinndüsen 6, 8 und 9 führen eine Vorverdichtung durch, so daß der Glätter stets unter gleichen Arbeitsbedingungen wirken kann. Durch geeignete Wahl der Größe und Abstufung der Düsenbohrungen sowie durch die Zahl derDüsen ist man in derLage, mit der gleichen Vorrichtung in sehr weitem Maße die verschiedensten Drahtdurchmesser mit verschiedener Asbestzugabe zu verspinnen.The spinnerets 6, 8 and 9 perform a pre-compression so that the straightener can always work under the same working conditions. Through suitable Choice of size and graduation of the nozzle bores as well as the number of nozzles one is able to use the same device to a very large extent the most varied Spinning wire diameters with various additions of asbestos.
