Description

Einrichtung zum Nachbearbeiten der vom Grat befreiten Längsnaht eines durch Schweißen geschlossenen Schlitzrohres, die hinter der Entgratvorrichtung angeordnet ist Bei der Herstellung von Rohren oder Rohrprofilen aus einem flachen Band wird aus dem Band durch Einrollen um die Längsachse ein Schlitzrohr gebildet, dessen Schlitzkanten mit Hilfe von rollenförmigen Elektroden, denen niedergespannter Strom zugeführt wird, oder auf induktivem Wege auf Schweißhitze erwärmt werden. Die erhitzten Kanten werden mit Hilfe von seitlichen Stauchrollen zusammengepreßt, so daß sie miteinander verschweißen. Infolge des Aufeinan derpressens der Kanten des Schlitzrohres entsteht ein Schweißgrat, der unmittelbar nach dem Schweißen, d. h. also noch in glühendem Zustand, abgehobelt oder durch Besäumen, Umlegen, Verhämmern unsichtbar gemacht wird. Will man nun Bänder, die z. B. mit Aluminium oder Kunststoff oder Kunststoffolie plattiert sind, zu Rohren oder anderen Hohlprofilen verarbeiten, so wird durch derartige Maßnahmen zur Bearbeitung der Schweißnaht die Plattierung im Bereich der Schweißnaht beschädigt oder ganz beseitigt. Dadurch ist das fertige Rohr an dieser Stelle nicht mehr rostgeschützt und zudem unansehnlich.Device for reworking the longitudinal seam of a by welding closed slot tube, which is arranged behind the deburring device is used in the manufacture of pipes or pipe profiles from a flat strip formed from the tape by rolling around the longitudinal axis of a slotted tube whose Slit edges with the help of roller-shaped electrodes, which low-voltage electricity is supplied, or heated inductively to welding heat. The heated ones Edges are pressed together with the help of side compression rollers so that they weld together. As a result of the pressing of the edges of the slotted tube on one another a weld burr is created, which immediately after welding, i. H. so still in red-hot, planed or invisible by trimming, flipping or hammering is made. If you want to tapes that z. B. with aluminum or plastic or Plastic foil are clad, processed into pipes or other hollow profiles, thus, by such measures for processing the weld seam, the cladding becomes damaged or completely removed in the area of the weld seam. This is the finished one Pipe at this point no longer protected against rust and also unsightly.

Diesem Mangel wird gemäß der vorliegenden Erfindung nun dadurch abgeholfen, daß die Nachbearbeitung der vom Grat befreiten Schlitznaht eines aus plattiertem Material gefertigten Rohres durch eine Spritzpistole erfolgt, die auf die Stellen, an denen die Plattierung beschädigt oder beseitigt worden ist, Außenplattierungsmaterial aufträgt. Die Spritzpistole kann das Plattierungsmaterial, z. B. Aluminium als Aluminiumdraht oder Kunststoff oder Kunststoffolie bei Schmelztemperatur des Aluminiums oder Kunststoffs verspritzen. Eine innige Verbindung des in feiner Verteilung aufgespritzten Plattierungsmaterials mit der Schweißnaht ist durch deren hohe Temperatur, bei der sie sich noch im glühenden Zustand befinden kann, gesichert. Notfalls kann durch eine zusätzliche induktive Erwärmung die Temperatur der Schweißnaht derjenigen des verspritzten Materials angeglichen werden.According to the present invention, this deficiency is now remedied by that the post-processing of the burr-free slot seam of a clad Material manufactured pipe is carried out by a spray gun, which is on the places, where the plating has been damaged or removed, external plating material applies. The spray gun may use the plating material, e.g. B. aluminum as aluminum wire or plastic or plastic film at the melting temperature of the aluminum or plastic splash. An intimate connection between the finely sprayed plating material with the weld is due to its high temperature at which it is still glowing State can be secured. If necessary, by an additional inductive Heating the temperature of the weld is adjusted to that of the sprayed material will.

Eine schematische Darstellung des Schweißteils der Einrichtung zur Herstehm@g von Rohren od. dgl. aus plattierten Bändern zeigt die Zeichnung in einer Seitenansicht bzw. einem senkrechten Querschnitt an den der Stromzuführung dienenden Elektroden. 1 ist das mit Hilfe nicht dargestellter Walzen um die Längsachse eingerollte Schlitzrohr, das mit Hilfe der rollenförmigen Elektroden 2 und 3 durch Widerstandserhitzung auf Schweißhitze gebracht und an den Schlitzkanten unter Zusammenpressung derselben mittels nicht dargestellter seitlicher Stauchrollen verschweißt wird. Hinter der Schweißstelle ist ein Hobelstahl 4 angeordnet, der die entstandene Schweißwulst 5 abhobelt. Diesem Hobel ist eine Spritzpistole 6 nachgeschaltet, die auf die beim Abhobeln der Schweißwulst bloßgelegten, noch heißen Stellen Plattierungsmaterial in feiner Verteilung aufspritzt. Dadurch werden diese Stellen wieder gegen Rost geschützt, und das fertige Rohr erhält ein einheitliches Aussehen.A schematic representation of the welding part of the device for Manufacture of pipes or the like from plated strips shows the drawing in one Side view or a vertical cross section of the power supply serving Electrodes. 1 is rolled around the longitudinal axis with the aid of rollers, not shown Slotted tube, which with the help of the roller-shaped electrodes 2 and 3 by resistance heating brought to welding heat and pressed together at the slot edges is welded by means of lateral compression rollers, not shown. Behind the Welding point is a planing steel 4, which the resulting weld bead 5 planes. This plane is followed by a spray gun 6, which is based on the Planing off the weld bead, exposed, still hot spots, cladding material sprayed on in fine distribution. This will prevent these spots from rusting again protected, and the finished pipe is given a uniform appearance.
