Abstract

Die Erfindung betrifft einen Mehrrollen-Schweißrollenbock für das Hochfrequenzschweißen von Rohren. Um einen Mehrrollen-Schweißrollenbock zu schaffen, der eine Einstellung desselben auf unterschiedliche Wanddicken des zu verschweißenden Schlitzrohres im gleichen Durchmesserbereich ohne Umbau ermöglicht, wird vorgeschlagen, daß die Oberrolle im Kalibergrund geteilt ist und jede Rollenhälfte (1, 2) im Bereich der Luftspalte (3, 4) zwischen der Oberrolle und den beiden Unterrollen (5, 6) um die Rohrmittenachse schwenkbar gelagert ist.The invention relates to a multi-roller welding roller block for high-frequency welding of pipes. In order to create a multi-roller welding roller block that allows it to be adjusted to different wall thicknesses of the slotted tube to be welded in the same diameter range without modification, it is proposed that the top roller be divided in the caliber base and that each roller half (1, 2) in the area of the air gaps (3 , 4) between the upper roller and the two lower rollers (5, 6) is mounted pivotably about the pipe center axis.

Die Erfindung betrifft einen Schweißrollenbock für das Hochfrequenzschweißen von Rohren nach dem Oberbegriff des Patentanspruchs.The invention relates to a welding roller block for high-frequency welding of pipes after Generic term of the claim.

Bei einer Wiöe»standsschweißanlage älterer Bauart gemäß der US-PS 24 17 594 ist es bekannt, zwei Rolienhälften im Bereich eines Luftspaltes zwischen einer Oberwelle und zwei Untenvellen um die Rohrmitteiachse schwenkbar zu lagern.With a Wiöe »standing welding system of an older type according to US-PS 24 17 594 it is known to have two roller halves in the area of an air gap between a top shaft and two bottom shafts around the pipe center axis to be pivoted.

Ferner ist zum HF-Schweißen von Rohren aus der US-PS 29 33587 ein Schweißrollenbock bekannt, der eine Oberrolle aufweist, die im Kalibergrund geteilt ist.Furthermore, a welding roller block is known for the HF welding of pipes from US-PS 29 33587, the one Has top roller, which is divided in the caliber base.

Andere Rollenanordnungen für Schweißrollenböcke zum HF-Schweißen sind als Zwei- oder Mehrrollensysterne bekanntOther roller arrangements for welding roller blocks for HF welding are as two- or multi-roller systems known

Für die freie Au>;ormu^ des äußeren Schweißgrates wird hier bei zwei Oberrollen ein '.uftspalt zwischen den Rollen eingestellt, der etwa der 1,5fachen Wanddikke des zu verschweißenden Schlitzroh· -?s entspricht. Bei einer Oberrolle wird eine dem äußeren Schweißgrat entsprechende Mittelnut vorgesehen. Nachteilig bei dieser Anordnung ist, daß bei Veränderung der Wanddicken die Rollen zur Anpassung der Luftspalte bzw. Nuten ausgetauscht werden müssen. Durch diese Maßnahmen werden neben zusätzlichen Oberrollen für die Schweißung der gesamten Wanddickenpalette auch Umbauzeiten in erheblichem Umfangerforderlich.For the free au>; ormu ^ of the outer sweat ridge there is an air gap between two upper rollers set to the rollers, which corresponds to about 1.5 times the wall thickness of the slotted tube to be welded. at a central groove corresponding to the outer weld burr is provided for an upper roller. Disadvantageous with This arrangement is that when the wall thickness changes, the rollers to adjust the air gap or Grooves need to be replaced. As a result of these measures, in addition to additional top roles for the Welding of the entire range of wall thicknesses also requires considerable conversion times.

Aufgabe der Erfindung ist es einen Schweißrollenbock zu schaffen, der eine einfache und schnelle Einstellung desselben auf unterschiedliche Wanddicken des zu verschweißenden Schlitzrohres im gleichen Durchmesserbereich ermöglicht.The object of the invention is to create a welding roller block that is quick and easy to adjust same to different wall thicknesses of the slotted tube to be welded in the same diameter range enables.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß durch die Merkmale nach dem kennzeichnenden Teil des Patentanspruchs.This object is achieved according to the invention by the features according to the characterizing part of the claim.

Der erfindungsgemäße Schweißrollenbock bietet die vorteilhafte Möglichkeit der stufenlosen Einstellung der Breite der Mittelnut auf die jeweilige Wanddicke. Durch die erfindungsgemäße Anordnung entfallen zusätzliche Oberrollen, d. h. die Lagerhaltung wird, wie auch die Umbauzeit verringert.The welding roller block according to the invention offers the advantageous possibility of stepless adjustment of the Width of the central groove on the respective wall thickness. The arrangement according to the invention eliminates additional Top rollers, d. H. storage is reduced, as is the conversion time.

In den Zeichnungen ist eine mögliche Anordnung des erfindungsgemäßen Schweißrollenbockes mit drei Rollen schematisch dargestellt.The drawings show a possible arrangement of the welding roller block according to the invention with three rollers shown schematically.

Roilenböcke gemäß der Erfindung sind auch mit mehr als drei Rollen denkbar, wobei die Oberrolle bzw. -rollen in gleicher Weise verschwenkt werden. Es zeigtRoilen stands according to the invention are also conceivable with more than three rollers, the top roller or rollers be pivoted in the same way. It shows

In den Zeichnungen ist die Oberrolle im Bereich der Mittelnut 7 in die Rollenhälften 1 und 2 geteilt. DurchFig. 1 shows the position of the rollers with a minimal central groove F i g. 2 F i g. 1 with maximum central groove.
In the drawings, the upper roller is divided into roller halves 1 and 2 in the area of central groove 7. By

Patentanspruch:Claim: Schweißrollenbock für das Hochfrequenzschweißen von Rohren mit einer Oberrolle, die im Kalibergrund geteilt ist und deren Rollenhälften im Bereich der Luflspaite zwischen der Oberrolle und den benachbarten Rollen um die Rohrmittenachse schwenkbar gelagert sind, dadurch gekennzeichnet, daß die Breite der Mittelnut (7) zwischen den Rollenhälften (1, 2) in Abhängigkeit von der Wanddicke des Schlitzrohres stufenlos einstellbar istWelding roller block for high-frequency welding of pipes with a top roller in the bottom of the caliber is divided and their roll halves in the area of the Luflspaite between the top roll and the adjacent rollers are pivotably mounted about the pipe center axis, characterized in that that the width of the central groove (7) between the roller halves (1, 2) as a function of the wall thickness of the slotted tube is continuously adjustable gleichmäßiges Verschwenken der beiden Rollenhälften 1 und 2 um die Rohrachse kann die Breite der Mittelnut 7 stufenlos in einem dem Rohrdurchmesser entsprechenden Bereich (z. B. von 2—8 mm bei einem Durchmesserbereich von 25—50 mm) eingestellt werden. Bei größeren Durchmessern wird das Maß der Verschwenkbarkeit ebenfalls größer.Uniform pivoting of the two roller halves 1 and 2 around the pipe axis can reduce the width of the central groove 7 continuously in a range corresponding to the pipe diameter (e.g. from 2–8 mm for a diameter range from 25-50 mm). With larger diameters, the degree of pivotability becomes also bigger. Die beiden Unterrollen 5 und 6 sind in bekannter Weise fest angeordnet, so daß sich die beiden Luf'spalten 3 und 4 bei Verstellung der Rollenhälflen 1 und 2 verändern.The two lower rollers 5 and 6 are fixedly arranged in a known manner, so that the two air gaps 3 and 4 change when adjusting the roller halves 1 and 2.
