Description

Die Erfindung betrifft eine Vorrichtung zum kontinuierlichen Ringwellen von Rohren oder rohrförmigen Elementen, insbesondere Kabelkomponenten, mit wenigstens einem um eine eigene Achse drehbaren Wellrad, das zusätzlich um das zu wellende rohrförmige Element rotiert.The invention relates to a device for continuous Ring waves of pipes or tubular elements, in particular Cable components, with at least one by one own axis rotatable shaft gear, which in addition to the undulating tubular element rotates.

Es ist bekannt, zum Ringwellen von geschweißten Metallrohren oder Kabelelementen (Kabelmäntel oder Außenleiter von Koaxialkabeln) - im folgenden als Rohre bezeichnet - in kontinuierlicher Arbeitsweise ein Glattrohr, vorzugsweise ein längsnahtgeschweißtes Glattrohr, durch eine Buchse hindurchzuführen, wobei unmittelbar hinter der Buchse ein oder mehrere Wellwerkzeuge in das Glattrohr greifen. Die Wellwerkzeuge bestehen aus Rädern, in die in definierten Abständen mit abgeschrägten Enden versehene Gleitsteine eingesetzt sind. Die Wellung wird dadurch erzeugt, daß die Wellräder um das zu wellende Rohr rotieren und gleichzeitig entsprechend der Geschwindigkeit des Bewegungsvorschubs des zu wellenden Rohres um ihre eigene Achse drehen. It is known for ring corrugation of welded metal pipes or cable elements (cable sheaths or outer conductors of coaxial cables) - hereinafter referred to as pipes - in continuous Operation a smooth tube, preferably a longitudinally welded smooth tube, to pass through a bushing, one or more directly behind the socket Grip corrugated tools into the smooth tube. The corrugated tools consist of wheels at defined intervals sliding blocks with bevelled ends are used are. The corrugation is generated in that the corrugated wheels around rotate the pipe to be corrugated and at the same time accordingly the speed of the movement feed of the undulated Rotate the tube around its own axis.

So sind aus der deutschen Patentschrift Nr. 893 784, den deutschen Auslegeschriften 1 272 865, 21 22 906 und 2 309 215 Vorrichtungen zur Herstellung einer Ringwelle unter Verwendung von Gleitsteinen oder Wälzrädern bekannt, die jedoch nur in der Lage sind, ausgehend von einem gegebenen Glattrohrdurchmesser, ein Wellrohr herzustellen, das maximal den gleichen Durchmesser hat wie das Glattrohr.So are from German Patent No. 893 784, the German designation 1 272 865, 21 22 906 and 2 309 215 devices for producing a ring shaft using known from sliding blocks or roller wheels, however are only able, starting from a given smooth tube diameter, to produce a corrugated tube that the maximum has the same diameter as the smooth tube.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung nach dem Gattungsbegriff des Anspruchs 1 zu schaffen, mit dem die Herstellung eines Wellrohrs ermöglicht wird, dessen Durchmesser größer ist als der Ausgangsdurchmesser des Glattrohres. Die Erfindung löst diese Aufgabe dadurch, daß zusätzlich zum Antrieb für die Rotation des Wellrades um das zu wellende rohrförmige Element ein drehzahlregelbarer Antrieb für die Drehung um die eigene Achse vorgesehen ist.The invention has for its object a device to create according to the preamble of claim 1 with which enables the production of a corrugated tube, the Diameter is larger than the initial diameter of the Smooth tube. The invention solves this problem in that in addition to the drive for the rotation of the corrugated wheel around the tubular element to be corrugated, a speed-controllable drive is intended for rotation about its own axis.

Durch eine stufenlose Regelbarkeit der Drehzahlen der Wellräder, die höher oder niedriger sein können als die dem Vorschub des zu wellenden Rohres entsprechende Drehzahl, kann das Material des zu wellenden Glattrohres gegen die Gleitsteine der Wellräder gedrückt werden, so daß sich das Rohrmaterial zu einem größeren Außendurchmesser aufschieben läßt. Da entsprechend der linearen Vorschubgeschwindigkeit v des Glattrohres und der stufenlos einstellbaren Drehzahl n1 des Rotors in Verbindung mit der stufenlos einstellbaren Drehzahl n2 des Wellrades um seine eigene Achse die Möglichkeit gegeben ist, die Wellform zu optimieren, läßt sich ohne Schwierigkeiten die Wellform einstellen, die für das Wellrohr aus mechanischen oder elektrischen Gründen erwünscht ist. Vorzugsweise wird der Antrieb der Wellräder um ihre eigene Achse durch ein Planetengetriebe übertragen. Das Planetenrad ist fliegend in einem die Wellräder tragenden und um das zu wellende Rohr drehenden Rotor gelagert. Vorteilhaft ist es ferner, alle rotierenden Teile auf einem einzigen rohrförmigen Kragträger anzuordnen und diesen einseitig fest mit einem ortsfesten Werkzeugständer zu verflanschen. Die Abstützung der rotierenden Teile auf dem tragenden ortsfesten Rohr kann mittels konzentrisch angeordneter Hohlwellen geschehen.Due to an infinitely variable speed of the corrugated wheels, which can be higher or lower than the speed corresponding to the feed of the pipe to be corrugated, the material of the smooth pipe to be corrugated can be pressed against the sliding blocks of the corrugated wheels, so that the pipe material becomes a larger outside diameter can be postponed. Since according to the linear feed speed v of the smooth tube and the infinitely adjustable speed n 1 of the rotor in connection with the infinitely adjustable speed n 2 of the corrugated wheel about its own axis, there is the possibility of optimizing the corrugated shape, the corrugated shape can be adjusted without difficulty, which is desirable for the corrugated pipe for mechanical or electrical reasons. The drive of the corrugated gears is preferably transmitted about their own axis by a planetary gear. The planet gear is overhung in a rotor that carries the corrugated gears and rotates around the tube to be corrugated. It is also advantageous to arrange all rotating parts on a single tubular cantilever beam and to flange them firmly on one side with a stationary tool stand. The rotating parts can be supported on the supporting, stationary tube by means of concentrically arranged hollow shafts.

Nach einer besonders zweckmäßigen Ausgestaltung des Erfindungsgedankens sind die Längen der Gleitsteine unter einem Winkel von etwa 0,5° bis 10° abgeschrägt, wodurch das Eintauchen auf die gewünschte Tiefe der Wellung nicht schlagartig erfolgt, sondern durch einen leichten konischen übergang.According to a particularly useful embodiment of the inventive concept are the lengths of the sliding blocks under one Angle of about 0.5 ° to 10 ° beveled, which makes immersion not abruptly to the desired depth of the curl takes place, but through a slight conical transition.

Dem gleichen Zweck dient ein weiteres vorteilhaftes Merkmal der Erfindung, wonach die Gleitsteine, die aus einem verschleißfesten Material bestehen, im Querschnitt konisch ausgebildet sind und keilförmig in das zu wellende Material eindringen. Die divergierende Dickenänderung entspricht einem Keilwinkel von etwa 0,5° bis 2°.Another advantageous feature serves the same purpose of the invention, according to which the sliding blocks made of a wear-resistant Material consist of a conical cross section and are wedge-shaped in the material to be corrugated penetration. The divergent change in thickness corresponds a wedge angle of approximately 0.5 ° to 2 °.

Als besonders vorteilhaft hat sich eine axiale Verschiebbarkeit der Wellräder auf ihren Antriebswellen erwiesen. Auf diese Weise lassen sich bei gegebenen Rohrabmessungen unterschiedliche Eindringtiefen der Gleitsteine in die Rohrwand festlegen, die das Material des Rohres in Längsrichtung aufschieben.Axial displaceability has proven to be particularly advantageous of the corrugated wheels on their drive shafts. On In this way, different pipe dimensions can be used Penetration depths of the sliding blocks in the pipe wall determine which slide the material of the pipe in the longitudinal direction.

Weitere den Erfindungsgegenstand vorteilhaft gestaltende Merkmale sind in den Ansprüchen angegeben.Further advantageously shaping the subject of the invention Features are given in the claims.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt und nachstehend erläutert. Es zeigen:

  • Figur 1 die Gesamtansicht einer Einrichtung zur Herstellung eines Wellrohres mit der Wellvorrichtung,
  • Figur 2 die Wellvorrichtung z. T. im Längsschnitt zur Herstellung eines Wellrohres mit einem Durchmesser < 30 mm,
  • Figur 3 einen Querschnitt durch die Wellvorrichtung im Bereich der Drehachsen der Wellräder und
  • Figur 4 die Wellvorrichtung z. T. im Längsschnitt für Wellrohre mit einem 30 mm überschreitenden Durchmesser.
    • In the drawing, an embodiment of the subject of the invention is shown schematically and explained below. Show it:
  • FIG. 1 shows the overall view of a device for producing a corrugated tube with the corrugating device,
  • Figure 2 shows the corrugator z. T. in longitudinal section for the production of a corrugated tube with a diameter <30 mm,
  • Figure 3 shows a cross section through the corrugating device in the region of the axes of rotation of the corrugated wheels and
  • Figure 4 shows the corrugated device z. T. in longitudinal section for corrugated pipes with a diameter exceeding 30 mm.

    • Von einer Spule 1 wird das zu formende Metallband 2 gezogen und zwischen zwei nicht dargestellten Rundmesserpaaren auf Maß geschnitten und in der Verformstufe mit Hilfe eines Rollenpaares 3 zu einem Schlitzrohr verformt. Mit Hilfe der Schweißeinrichtung 4 für eine Lichtbogen- oder Laserschweißung werden die Bandkanten des Schlitzrohres miteinander verschweißt. Das geschlossene, aber noch glatte Rohr 5 wird von dem Abzug 6, beispielsweise einem Spannzangenabzug, gefaßt und der Wellvorrichtung 7 zugeführt. Das die Wellvorrichtung verlassende gewellte Rohr 8 kann auf eine übliche Kabeltrommel 9 aufgewickelt werden.The metal strip 2 to be formed is drawn from a coil 1 and between two pairs of round knives, not shown Cut to size and in the deformation stage with the help of a Rolled pair 3 deformed into a slotted tube. With the help of Welding device 4 for an arc or laser welding the band edges of the slotted tube with each other welded. The closed, but still smooth tube 5 will from the trigger 6, for example a collet trigger and supplied to the corrugating device 7. That the corrugating device leaving corrugated tube 8 can be on a usual Cable drum 9 are wound up.

    Wie die Figuren 2 und 4 zeigen, kann die Wellvorrichtung in ihrer Gesamtheit unterschiedlich zur Vorschubrichtung des zu wellenden Rohres ausgerichtet montiert werden. Für Rohrdurchmesser unter 30 mm ist es beim Aufschieben des Materials von Vorteil, wenn der Abstand zwischen der Spannzange 6 im Spannzangenabzug und der Wellvorrichtung möglichst gering gehalten wird, damit das dünne Rohr unter der Druckkraft beim Aufschieben nicht ausknickt. As shown in FIGS. 2 and 4, the corrugation device in their entirety different from the feed direction of the to be aligned to corrugated pipe. For pipe diameter It is less than 30 mm when the material is pushed on beneficial if the distance between the collet 6 in the collet trigger and the corrugation device as low as possible is held so the thin tube under the compressive force does not buckle when pushed open.

    Bei einem Rohrdurchmesser über 30 mm besteht keine Gefahr, daß das Rohr unter der Druckkraft ausknickt. Deshalb kann die Vorrichtung - bezogen auf die Vorschubrichtung des Rohres - in ihrer Gesamtheit um 180° gedreht aufgebaut werden. Das gewellte Rohr 8 kann dadurch ablaufen, ohne durch die Wellenvorrichtung hindurchgeleitet zu werden.With a pipe diameter over 30 mm there is no danger that the pipe buckles under the pressure. Therefore can the device - based on the feed direction of the Rohres - in their entirety rotated by 180 °. The corrugated tube 8 can thereby run through without Wave device to be passed.

    Die Wellvorrichtung ist in den Figuren 2 und 4 vergrößert schematisch dargestellt. Mit 5 ist das in Pfeilrichtung ankommende geschweißte Glattrohr bezeichnet, das durch die Wellerbuchse 10 an die Wellräder 11 herangeführt wird. Die Wellerbuchse 10 ist an ihrem Auslaufende konisch ausgebildet, um sie so nahe wie möglich an die Wellräder 11 heranreichen zu können. Dadurch wird das zu wellende Rohr äußerst exakt positioniert. In die Wellräder sind die aus Hartmetall bestehenden Gleitsteine 12 gleichmäßig auf dem Umfang verteilt eingesetzt. Die Wellräder sind in einem Rotor 13 gelagert, durch den sie in Richtung des Pfeils 25 um das zu wellende Rohr herumbewegt werden. Der Rotor wird von einem nicht näher dargestellten Antrieb 15 angetrieben.The corrugated device is enlarged in FIGS. 2 and 4 shown schematically. With 5 is the arriving in the direction of the arrow welded smooth tube referred to by the Weller bushing 10 is brought up to the corrugated wheels 11. The Weller bushing 10 is conical at its outlet end, to get them as close as possible to the corrugated wheels 11 to be able to. This makes the pipe to be corrugated extreme exactly positioned. The corrugated wheels are made of hard metal existing sliding blocks 12 evenly distributed over the circumference used. The corrugated wheels are mounted in a rotor 13, through which they move in the direction of arrow 25 undulating pipe to be moved around. The rotor is made by one Drive 15 not shown driven.

    Im Rotor 13 ist eine Vorlegewelle 14 fliegend gelagert. Sie läuft deshalb wie die Wellräder um das zu wellende Rohr herum. An ihrem äußeren Ende trägt die Vorlegewelle ein Stirnrad 14a und ein Kegelritzel 14b. Das Kegelritzel greift in ein auf einer Vielnutwelle 18 sitzendes Kegelrad 21. Von der Vielnutwelle wird gleichzeitig das Wellrad 11 getragen. Ein nicht näher beschriebener Antrieb 16 treibt über eine Hohlwelle 17 ein Stirnrad 17a an, das mit dem Ritzel 14a kämmt. Das Drehmoment wird somit über das Kegelritzel 14b auf das Kegelrad 21 des Wellrades 11 übertragen. Das Stirnrad 17a wirkt somit wie das Sonnenrad eines Planetengetriebes auf die Vorlegewelle mit dem Ritzel 14a als Planetenrad. Das Verhältnis der Rotordrehzahl zur Stirnraddrehzahl wird beim Anfahren fest vorgegeben. Beim Erreichen der Produktionsgeschwindigkeit kann die Feinregelung zur 0ptimierung der Wellung vorgenommen werden. A countershaft 14 is overhung in the rotor 13. she therefore runs like the corrugated wheels around the pipe to be corrugated around. The countershaft enters at its outer end Spur gear 14a and a bevel pinion 14b. The bevel pinion engages in a bevel gear 21 seated on a multi-slot shaft 18 the multi-spline shaft, the corrugated wheel 11 is carried at the same time. A drive 16, not described in detail, drives via a Hollow shaft 17 a spur gear 17a, which with the pinion 14a combs. The torque is thus via the bevel pinion 14b transferred to the bevel gear 21 of the corrugated gear 11. The spur gear 17a thus acts like the sun gear of a planetary gear on the countershaft with the pinion 14a as a planet gear. The ratio of the rotor speed to the spur gear speed is fixed when starting. When the production speed is reached can fine control for optimization the curl.

    Mit der Figur 3 ist das Wellrad 11 mit seiner Verstellmöglichkeit schematisch dargestellt. Durch das Kegelrad 21 ist die Vielnutwelle mit dem Vorgelege 14, 14a, 14b verbunden und wird durch dieses angetrieben. Auf der Vielnutwelle ist das Wellrad axial verschiebbar. Der Verstellung dient eine überwurfmutter 19. Zur Fixierung der eingestellten Position wird eine Kontermutter 20 gegen die überwurfmutter 19 gezogen. Da sich durch die Verlagerung des Wellrades Unwuchten ergeben, ist ein nicht dargestellter Massenausgleich vorgesehen.3 shows the corrugated wheel 11 with its adjustment possibility shown schematically. Through the bevel gear 21 the multi-spline shaft is connected to the countershaft 14, 14a, 14b and is driven by this. On the multi-slot shaft is the shaft gear is axially displaceable. The adjustment is used union nut 19. For fixing the set position a lock nut 20 is pulled against the union nut 19. Because unbalance occurs due to the displacement of the wave gear result, a mass balance, not shown, is provided.

    Der Rotor trägt bei dem gezeigten Ausführungsbeispiel zwei Wellräder. Ihre Vielnutwellen sind in Tragarmen 23 und 24 gelagert, die miteinander verschraubt und mit dem Rotor verbunden sind. Das Verbindungselement ist aus Gründen einer besseren übersichtlichkeit nicht dargestellt. Die Abdeckung des Rotors ist mit 26 bezeichnet.The rotor carries two in the embodiment shown Corrugated wheels. Their multi-slot shafts are in support arms 23 and 24 stored, screwed together and connected to the rotor are. For reasons of connection, the connecting element is one better clarity not shown. The cover of the rotor is designated 26.

    Die gesamte Vorrichtung ist mit ihren drehenden Teilen, nämlich Rotor 13, Vorgelege 14, 14a, 14b, Wellräder 11 und Hohlwelle 17, auf einem rohrförmigen, vorkragenden Träger 27 gelagert. An seinem äußersten Ende ist der Träger mit einem Flansch 28 versehen und über diesen mit einem ortsfesten Werkzeugständer 29 fest verschraubt.The entire device is with its rotating parts, namely Rotor 13, countershaft 14, 14a, 14b, corrugated wheels 11 and Hollow shaft 17, on a tubular, projecting support 27 stored. At its extreme end is the carrier with one Provide flange 28 and over it with a stationary Tool stand 29 screwed tight.

    Die Wellvorrichtung der Figur 4 unterscheidet sich von der der Figur 2 lediglich dadurch, daß der rohrförmige Träger 27 zur Wellung eines Rohres mit einem Durchmesser > 30 mm ausgebildet ist, also einen größeren lichten Durchmesser zeigt, in welchen die Wellerbuchse 10 eingezogen ist. Die Anordnung kann dadurch um 180° zur Lage der Vorrichtung gemäß Figur 2 gedreht zur Anwendung gelangen, so daß der gewellte Teil des Rohres die Vorrichtung unmittelbar verläßt und nicht durch das Tragrohr 27 hindurchgeführt werden muß. Die Drehrichtung der Wellräder ist dementsprechend entgegengesetzt gerichtet.The corrugated device of Figure 4 differs from that of Figure 2 only in that the tubular support 27th designed to corrugate a pipe with a diameter> 30 mm is, i.e. shows a larger clear diameter, in which the Wellerbuchse 10 is drawn. The order can thereby 180 ° to the position of the device according to FIG. 2 applied rotated so that the corrugated part of the Rohres leaves the device immediately and not through the support tube 27 must be passed. The direction of rotation the corrugated wheels are accordingly directed in opposite directions.
