Abstract

Wires (1) of circular or esp. non-circular cross-section are twisted together without back-twisting to form a cable with alternating twist. The twisting head (3) guides each wire in an arc shape over guide rollers (5). The roller profile is adapted to suit the cross-section of the wire (1).

Claims (4)

AT 402 305 B Die Erfindung betrifft eine Vorrichtung zur Herstellung einer Kabelverseilung (4) aus Einzeladern -insbesondere Adern nichtrunden Querschnitts wie z.B. für Hochspannungskabel aus drei oder vier sektorförmigen Leitern (1) aus Kupfer oder Aluminium mit großen Querschnitten mit einer Kunststoffisolierung (2) -mit wechselnder Schlagrichtung. 5 Vorrichtungen zum Verseilen mit wechselnder Schlagrichtung sind für runde Adern bekannt. Sektorförmige Drähte müssen jedoch, andere als runde Drähte, wegen ihrer Passform im Seil zusätzlich einmal pro Schlag (Umdrehung) um ihre Achse verdrillt werden (Verseilen ohne Rückdrehung). Das bedeutet, daß hohe Drehmomente auf die einzelnen Drähte/Adern (bezogen auf deren Längsachsen) aufgebracht werden müssen. 70 Die EP-A1 -0582802 beschreibt eine Verseilmaschine mit wechselnder Schlagrichtung für Drähte, runden Querschnitts. Sie besteht aus einer feststehenden Einlaufführung in einen Drallspeicher und einem hin- und herrotierenden Legekopf mit Führungen für jeden Draht. Wenn nun die Drähte um ihre Achse verdrillt werden sollen, dann müssen sie im Legekopf drehfest gehalten werden. Es ist naheliegend, dafür formschlüssig zum Drahtquerschnitt angepaßte Führungen und Führungsrollen einzusetzen. Jedoch ist das, 75 abhängig von der Festigkeit und Art (AI, Cu - eindrähtig massiv oder mehrdrähtig verseilt) des verwendeten Leiters, praktisch kaum möglich, ohne daß die Leiterisolierung aus Kunststoff beschädigt wird. Zumal die Form der kreissektorförmigen Leiterquerschnitte mit 90· oder 120” Sektorwinkel durch relativ große Abrundungen an den Ecken nur wenig "Angriff" für eine Profilführung bietet. Bei der vorliegenden Erfindung werden die, die Drehkraft aufbringenden Profilrollen (5, 6) am Legekopf 20 (3) so in einem Bogen angeordnet, daß für das Verdrehen der Adern (1 ...Leiter, 2...Isolierung) ein Kurbelarm gebildet wird, mit dem Radius R, sodaß die jeweilige Umfangkraft Pu so klein wird daß die Aderisolierung aus Kunststoff nicht beschädigt wird. Fig. 1 und Fig. 2 zeigen beispielhaft einen solchen Legekopf (3), wobei der, in Drahtlaufrichtung (7) davorliegende "gestreckte Drallspeicher" nicht dargestellt ist. Der Legekopf (3) ist in den Lagerstellen (10, 25 11) drehbar gelagert, er wird vom Motor (12) und dem Riemenantrieb (13) oszilierend angetrieben. Die einzelnen Drähte (1) mit ihrer Isolierung (2) kommen in Durchlaufrichtung (7) aus dem "Drallspeicher". Um nun die nötige Drehkraft zum Verdrillen der steifen Drähte um ihre Längsachsen nicht an den abgerundeten Ecken (14) der Drähte angreifen zu lassen, werden die Drähte aus ihrer eigentlich idealen gestreckten Lage bogenförmig nach außen geführt, sodaß jeder Draht (1) einen Hebelarm mit dem Radius 30 R bildet. Die erforderliche Umfangskraft Pu wird dadurch weitaus kleiner, sie hat dann die ganze Querschnittshöhe als Angriffslinie, sodaß die spezifische Flächenpressung klein genug wird, um die Isolierung (2) nicht zu beschädigen. Die Verseilung wird im Verseilnippel (9) gebildet und läuft in Richtung 8 in eine "Drallsperre" bekannter Art. In der dargestellten Fig. 1 wird beispielhaft die bogenförmige Führung aus mehreren kleineren Rollen 35 dargestellt, das verkleinert die Baugröße des Verseilkopfes. Es könnte aber auch jeweils nur eine einzige Rolle eventuell größeren Durchmessers (der Steifigkeit der Verseilelemente entsprechend) ausgeführt werden. Patentansprüche 40 1. Vorrichtung zur Herstellung einer Kabelverseilung (4) mit wechselnder Schlagrichtung aus Einzeldrähten (1) runden oder vornehmlich nicht runden Querschnitts, welche ohne Rückdrehung verseilt werden sollen, dadurch gekennzeichnet, daß der in wechselnder Drehrichtung antreibbare Legekopf (3) für jeden Draht eine bogenförmige Rollenführung aufweist, deren Rollenprofil (5) an die Querschnittsform 45 der Drähte (1) angepaßt ist.AT 402 305 B The invention relates to a device for producing a cable stranding (4) from single wires - in particular non-round cross-section wires, e.g. for high-voltage cables consisting of three or four sector-shaped conductors (1) made of copper or aluminum with large cross-sections with plastic insulation (2) - with changing direction of lay. 5 devices for stranding with alternating lay direction are known for round wires. However, sector-shaped wires, other than round wires, have to be twisted around their axis once per turn (rotation) due to their fit in the rope (stranding without reverse rotation). This means that high torques must be applied to the individual wires / wires (based on their longitudinal axes). 70 EP-A1-05822802 describes a stranding machine with alternating lay direction for wires with a round cross-section. It consists of a fixed inlet guide in a swirl storage and a back and forth rotating laying head with guides for each wire. If the wires are now to be twisted around their axis, then they must be held in the laying head so that they cannot rotate. It makes sense to use guides and guide rollers that are form-fitting to the wire cross-section. However, depending on the strength and type (Al, Cu - solid single-strand or stranded multi-strand) of the conductor used, this is practically impossible without damaging the plastic conductor insulation. Especially since the shape of the circular sector-shaped conductor cross-sections with 90 · or 120 ”sector angles due to relatively large roundings at the corners only a little " attack " for a profile guide. In the present invention, the profile rollers (5, 6) which apply the torque are arranged in an arc on the laying head 20 (3) in such a way that a crank arm is formed for the twisting of the wires (1 ... conductor, 2 ... insulation) is, with the radius R, so that the respective circumferential force Pu is so small that the wire insulation made of plastic is not damaged. 1 and 2 show an example of such a laying head (3), the " stretched swirl memory " in front of it in the wire running direction (7). is not shown. The laying head (3) is rotatably mounted in the bearing points (10, 25 11), it is driven by the motor (12) and the belt drive (13) in an oscillating manner. The individual wires (1) with their insulation (2) come from the " swirl store " in the direction of travel (7). In order not to allow the necessary torque to twist the stiff wires around their longitudinal axes at the rounded corners (14) of the wires, the wires are led outward from their actually ideal stretched position, so that each wire (1) has a lever arm with it forms the radius 30 R. The required circumferential force Pu is thereby much smaller, it then has the entire cross-sectional height as a line of action, so that the specific surface pressure is small enough not to damage the insulation (2). The stranding is formed in the stranding nipple (9) and runs in direction 8 in a " twist lock " Known type. In the illustrated FIG. 1, the arcuate guide made up of several smaller rollers 35 is shown as an example, which reduces the size of the stranding head. However, only a single roll of possibly larger diameter (corresponding to the rigidity of the stranding elements) could also be carried out in each case. Claims 40 1.
