Definitions
- the invention relates to a method for producing longitudinally welded metallic tubes according to the preamble of claim 1, such a method is known from EP 299 123 A known.
- a device for producing a longitudinally welded metal tube with an outer diameter of 1 to 6 mm is known.
- a metal strip is withdrawn in a continuous mode of operation from a supply reel, formed by a mold consisting of several sets of molds forming a tube with a longitudinal slot, and the longitudinal slot welded.
- the slit tube is passed through a tool which holds the band edges of the slotted tube together.
- the tool consists of two halves which each have on their adjacent surface a groove with a radius of curvature corresponding to the outer radius of curvature of the slot tube.
- the tool has a recess which allows access to the beam of a laser welding device for welding the longitudinal slot of the tube.
- the welded tube passes behind the recess a second portion of the tool, which is intended to prevent springback of the strip edges in the still "soft" weld pool and to ensure rapid cooling of the weld.
- a steel alloy is proposed as a material for the tool.
- a device for producing a metallic tube comprising a forming device that transforms an elongated metal strip to the tube, and a welding device that welds the two strip edges of the tube together in the welding area.
- a welding device that welds the two strip edges of the tube together in the welding area.
- the welding area at least one cooled solid body is provided, which contacts the continuous tube outside for cooling.
- the solid body has an opening which allows the passage of a laser beam for welding the longitudinal seam.
- the invention has for its object to improve the known method to the extent that large lengths of metallic tubes are produced trouble-free.
- the main advantage of the invention is the fact that by the arrangement of a ring of wear-resistant material in a water-cooled holder, the wear on the tool is so far reduced that lengths of several kilometers without interruption of production can be produced. This effect is exacerbated when the shape of the metal strip to the slotted tube takes place so that the slotted tube without springback of the band edges forms a nearly closed tube, so that the ring serves only to stabilize the closed tube.
- the inventive method is advantageously used for the production of optical fiber cables, which have a plurality of optical waveguides in a closed metal tube.
- FIGS. 1 and 2 schematically illustrated embodiments explained in more detail.
- FIG. 1 Fig. 3 is a side view of part of an apparatus for making thin metal tubes.
- a withdrawn from a tape supply no longer illustrated metal strip 1 is fed to a first forming roller group 2.
- the metal strip 1 is a stainless steel strip which has been cut to a width of 3.1 to 21.5 mm, for example, by means of a trimming device (also not shown). Before the first forming roll group 2, the metal strip 1 can be easily wetted with a lubricant to reduce the friction during molding.
- the first forming roll group 2 has two forming roll pairs 2a and 2b.
- the form roller pair 2a In the form roller pair 2a, only the band edge regions are initially rounded.
- the form roller pair 2b forms the metal strip 1 into a U-profile.
- the U-shaped metal band 1 a is fed to a device 3, which has a guide tube 3a, which projects into the U-shaped metal strip 1 a and opens behind the weld point.
- a guide tube 3a which projects into the U-shaped metal strip 1 a and opens behind the weld point.
- a second forming roller group 4 which consists of a first pair of forming rollers 4a and a second pair of forming rollers 4b, the U-shaped metal strip 1a is formed into a slotted tube 1b having an extremely small slit width.
- the slotted tube 1 b then passes into a tool 5, which on the basis of FIG. 2 will be described in more detail. Behind the tool 5 is located in the shortest possible distance, the laser welding device 6, in which the longitudinal slot is welded. At the finished optical cable 7 attacks a not shown trigger, behind which the cable 7 is then wound on a drum no longer shown.
- the welded metal tube can be reduced in diameter as needed, stretched and be relieved cooled to produce an excess length of the optical waveguide in the metal tube.
- FIG. 2 In the FIG. 2 is the tool 5 opposite FIG. 1 shown enlarged.
- the slit tube 1 b is pulled through a diamond ring 8, whose inner diameter is almost equal to the outer diameter of the slotted tube 1 b.
- the bore of the diamond ring 8 is almost cylindrical.
- the diamond ring 8 is arranged in a socket 9, which has a channel system 14 for cooling the diamond ring 8.
- the duct system 14 is fed by a feed 10 for cooling water.
- the version 9 is arranged in a holder 13.
- the tube emerging from the diamond ring 8 is surrounded by an annular nozzle 11 which blows a protective gas over the tube above the longitudinal slot of the tube in the direction of production.
- the protective gas is supplied to the nozzle 11 via a line 12.
- the shielding gas protects the weld area of the tube beyond the weld area.
- the forming roller groups 2 and 4 take over the entire forming work in the deformation of the metal strip to a slotted tube with extremely narrow slot.
- the closing and calming of the tube takes place through the diamond ring 8. This allows long service life of the diamond ring 8 even with hard materials for the metal strip.
- An improvement in smoothness can also be achieved by taking care in the edge rounding in the first forming roller group 2 that the outer radius of curvature of the edge region is selected to be somewhat larger than half the inner diameter of the diamond ring 8.
- tubes with an outer diameter of between 1 and 7 mm can be produced without errors in lengths of more than 100 km.

Description
Die Erfindung betrifft ein Verfahren zur Herstellung von längsnahtgeschweißten metallischen Röhrchen nach dem Oberbegriff des Anspruchs 1, ein solches Verfahren ist aus der
Aus der
Bei dieser Vorrichtung hat sich gezeigt, daß sich große Längen von mehreren Hundert Kilometern nicht störungsfrei herstellen lassen. Der Grund hierfür liegt in einem hohen Verschleiß des Werkzeugs, der daraus resultiert, daß das geformte Schlitzrohr einen offenen Spalt aufweist, der erst im Werkzeug vollständig geschlossen wird.In this device has been shown that large lengths of several hundred kilometers can not be produced trouble-free. The reason for this is a high wear of the tool, which results from the fact that the shaped slot pipe has an open gap, which is only completely closed in the tool.
Aus der
Beiden bekannten Lösungen ist gemeinsam, daß insbesondere bei harten Metallen für das Röhrchen, wie z. B. Edelstahl, das Werkzeug bzw. der Festkörper einem hohen Verschleiß unterliegen, und eine störungsfreie Fertigung großer Längen nicht möglich ist.Both known solutions have in common that especially in hard metals for the tube, such as. As stainless steel, the tool or the solid subject to high wear, and trouble-free production of long lengths is not possible.

Aus der
Der Erfindung liegt die Aufgabe zugrunde, das bekannte Verfahren dahingehend zu verbessern, daß große Längen metallischer Röhrchen störungsfrei herstellbar sind.The invention has for its object to improve the known method to the extent that large lengths of metallic tubes are produced trouble-free.
Diese Aufgabe wird durch die im Anspruch 1 erfaßten Merkmale gelöst.This object is achieved by the features detected in claim 1.
Der wesentliche Vorteil der Erfindung ist darin zu sehen, daß durch die Anordnung eines Ringes aus verschleißfestem Material in einer wassergekühlten Halterung, der Verschleiß am Werkzeug so weit reduziert ist, daß Längen von mehreren Kilometern ohne Unterbrechung der Fertigung herstellbar sind. Diese Wirkung wird noch verstärkt, wenn die Formgebung des Metallbandes zum Schlitzrohr so erfolgt, daß das Schlitzrohr ohne Rückfederung der Bandkanten ein nahezu geschlossenes Rohr bildet, so daß der Ring lediglich zur Stabilisierung des geschlossenen Rohres dient.The main advantage of the invention is the fact that by the arrangement of a ring of wear-resistant material in a water-cooled holder, the wear on the tool is so far reduced that lengths of several kilometers without interruption of production can be produced. This effect is exacerbated when the shape of the metal strip to the slotted tube takes place so that the slotted tube without springback of the band edges forms a nearly closed tube, so that the ring serves only to stabilize the closed tube.
Das erfindungsgemäße Verfahren wird vorteilhafterweise zur Herstellung von Lichtwellenleiterkabeln eingesetzt, welche eine Vielzahl von Lichtwellenleiter in einem geschlossenen Metallröhrchen aufweisen.The inventive method is advantageously used for the production of optical fiber cables, which have a plurality of optical waveguides in a closed metal tube.

Ein von einem nicht mehr dargestellten Bandvorrat abgezogenes Metallband 1 wird einer ersten Formrollengruppe 2 zugeführt. Bei dem Metallband 1 handelt es sich um ein Edelstahlband, welches beispielsweise mittels einer ebenfalls nicht mehr dargestellten Besäumeinrichtung auf eine Breite von 3,1 bis 21,5 mm geschnitten wurde. Vor der ersten Formrollengruppe 2 kann das Metallband 1 leicht mit einem Schmiermittel benetzt werden, um die Reibung während der Formgebung zu reduzieren.A withdrawn from a tape supply no longer illustrated metal strip 1 is fed to a first forming
Die erste Formrollengruppe 2 weist zwei Formrollenpaare 2a und 2b auf.The first forming
In dem Formrollenpaar 2a werden zunächst nur die Bandkantenbereiche gerundet. Das Formrollenpaar 2b formt das Metallband 1 zu einem U-Profil.In the
Das U-förmig gebogene Metallband 1 a wird einer Vorrichtung 3 zugeführt, welche ein Führungsrohr 3a aufweist, das in das U-förmige Metallband 1 a hineinragt und hinter dem Schweißpunkt mündet. Mit Hilfe des Führungsrohres 3a können mehrere von nicht dargestellten Vorratsspulen abgezogene Lichtwellenleiter sowie eine plastische Masse in das Metallröhrchen eingebracht werden.The U-shaped
In einer zweiten Formrollengruppe 4, welche aus einem ersten Formrollenpaar 4a und einem zweiten Formrollenpaar 4b besteht, wird das U-förmige Metallband 1 a zu einem Schlitzrohr 1 b mit extrem geringer Schlitzbreite geformt. Das Schlitzrohr 1 b gelangt dann in ein Werkzeug 5, welches anhand der
In der
Das Schlitzrohr 1 b wird durch einen Diamantring 8 gezogen, dessen Innendurchmesser nahezu gleich dem Außendurchmesser des Schlitzrohres 1 b ist. Die Bohrung des Diamantringes 8 ist nahezu zylindrisch. Der Diamantring 8 ist in einer Fassung 9 angeordnet, welche ein Kanalsystem 14 zur Kühlung des Diamantrings 8 aufweist. Das Kanalsystem 14 wird durch einen Zulauf 10 für Kühlwasser gespeist. Die Fassung 9 ist in einer Halterung 13 angeordnet.The
Das aus dem Diamantring 8 austretende Rohr ist von einer ringförmigen Düse 11 umgeben, die oberhalb des Längsschlitzes des Röhrchens ein Schutzgas in Fertigungsrichtung über das Röhrchen bläst. Das Schutzgas wird der Düse 11 über eine Leitung 12 zugeführt. Das Schutzgas schützt den Schweißnahtbereich des Röhrchens bis über den Schweißbereich hinaus.The tube emerging from the
Bei dem erfindungsgemäßen Verfahren übernehmen die Formrollengruppen 2 und 4 die gesamte Formarbeit bei der Verformung des Metallbandes zu einem Schlitzrohr mit extrem engem Schlitz. Das Schließen und Beruhigen des Rohres erfolgt durch den Diamantring 8. Dadurch sind hohe Standzeiten des Diamantringes 8 auch bei harten Werkstoffen für das Metallband möglich.In the method according to the invention, the forming
Eine Verbesserung der Laufruhe kann auch dadurch erzielt werden, daß bei der Kantenrundung in der ersten Formrollengruppe 2 darauf geachtet wird, daß der äußere Krümmungsradius des Kantenbereichs etwas größer gewählt wird als der halbe innere Durchmesser des Diamantringes 8.An improvement in smoothness can also be achieved by taking care in the edge rounding in the first forming
Mit Hilfe des erfindungsgemäßen Verfahren können Röhrchen mit einem Außendurchmesser zwischen 1 und 7 mm in Längen von mehr als 100 km fehlerfrei hergestellt werden.With the aid of the method according to the invention, tubes with an outer diameter of between 1 and 7 mm can be produced without errors in lengths of more than 100 km.
In der Beschreibung sind für die Formrollengruppen 2 und 4 jeweils nur zwei Formrollenpaare angegeben. Falls es für die Verformung des Metallbandes erforderlich sein sollte, können selbstredend auch mehr als zwei Formrollenpaare für eine oder beide Formrollengruppen 2 und 4 vorgesehen werden.In the description, only two pairs of form rollers are specified for the
