Description

Die Erfindung betrifft ein Verfahren zur automatischenThe invention relates to a method for automatic

Kontrolle und Steuerung der Entgratung und/oder der Schweißrollen beim HF-Längsnahtschweißen von Rohren und eine Vorrichtung zur Durchführung des Verfahrens.Monitoring and control of the deburring and / or the welding rollers in the HF longitudinal seam welding of pipes and a device for carrying out the Procedure.

Die Entgratkontrolle wurde bisher visuell durch das Bedienungspersonal vorgenommen. Die Kontrolle konnte hierbei erst am abgetrennten Rohr und somit zu spät durchgeführt werden.The deburring control was previously carried out visually by the operating personnel performed. The control could only be carried out on the severed pipe and thus closed to be carried out late.

Bekannt ist auch eine Überprüfung der Innenentgratung mittels Ultraschall. Nachteilig bei diesem Verfahren ist, daß die Prüfaussage undifferenziert bezüglich der verschiedenen Entgratfehler ist. Ein Erkennen sämtlicher Entgratfehler ist mit der Ultraschall-Überprüfung nicht möglich.It is also known to check the internal deburring by means of ultrasound. The disadvantage of this method is that the test statement is undifferentiated with regard to of the various deburring defects. A recognition of all deburring errors is with the ultrasound check is not possible.

Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, mit dem unmittelbar hinter der Entgratung auftretende Abweichungen vom Soll-Wert erkannt und anschließend daran umgehend behoben werden können, sowie eine Vorrichtung zur Durchführung des Verfahrens.The object of the invention is to create a method with which directly Any deviations from the target value that occur behind the deburring are detected and then can be remedied immediately, as well as a device for carrying out the Procedure.

Zur Lösung der Aufgabe wird erfindungsgemäß ein Verfahren und eine Vorrichtung vorgeschlagen, wie es/sie in den Patentansprüchen 1 und 3 beschrieben ist.To achieve the object, a method and a Device proposed as described in claims 1 and 3 is.

Eine Weiterbildung ergibt sich aus dem Anspruch 2.A further development results from claim 2.

Mit Hilfe der erfindungsgemäß vorgeschlagenen Vorrichtung lassen sich alle Fehler feststellen, zuordnen und ohne Unterbrechung der Fertigung beheben.With the aid of the device proposed according to the invention, Identify, assign and correct all errors without interrupting production.

In den beigefügten Zeichnungen ist eine mögliche Ausführungsform einer erfindungsgemäßen Vorrichtung schematisch dargestellt.In the accompanying drawings, one possible embodiment is a Device according to the invention shown schematically.

Es zeigen: Figur la eine im Rohr befindliche Vorrichtung Figur lb Querschnitt durch die in einem Rohr befindliche Vorrichtung in vergrößertem Maßstab Figur 2 eine Darstellung der Meßwerte im Vergleich zur Normalkontur Figur 3 Meßschema für die Vorrichtung.It shows: Figure la a device located in the tube Figure lb Cross-section through the device located in a tube on an enlarged scale FIG. 2 shows a representation of the measured values in comparison with the normal contour, FIG. 3, measurement scheme for the device.

Wie aus Figur la und b ersichtlich, ist die Vorrichtung in bekannter Weise an einem im Innern des Rohres befindlichen und geführten Gestänge 1 in einem Gehäuse 2 angebracht.As can be seen from Figure la and b, the device is known Way on a located inside the pipe and guided linkage 1 in one Housing 2 attached.

In dem Gehäuse 2 befinden sich im Winkel zur senkrechten Rohrachse Kopierrollen 3; ferner eine mittig zwischen diesen angeordnete wendelförmige Abtastrolle 5, die drehbar in einem beweglichen Rahmen 4 gelagert ist. Der Rahmen 4 besitzt ein Druckelement 6, welches über eine elektrische oder hydraulische Leitung 7 mit einem Anzeigeelement 8 bekannter Bauart, z.B. einemOszillator verbunden ist.In the housing 2 are at an angle to the vertical pipe axis Copy rollers 3; furthermore a helical scanning roller arranged centrally between these 5, which is rotatably mounted in a movable frame 4. The frame 4 has a pressure element 6, which via an electrical or hydraulic line 7 with a display element 8 of known type, for example an oscillator.

In Figur 2 ist ein Oszillatorbild mit einer Darstellung des Meßwertes (12) im Vergleich zur Normalkontur (11-) dargestellt.In Figure 2 is an oscillator image with a representation of the measured value (12) compared to the normal contour (11-).

Figur 3 zeigt ein Meßschema für eine erfindungsgemäße Vorrichtung.FIG. 3 shows a measurement scheme for a device according to the invention.

Bei Anwendung des vorgeschlagenen Verfahrens wird die Kontur der Rohrinnenoberfläche im Schweißnahtbereich (9) unmittelbar nach der Entgratung mit einer wendelförmigen Abtastrolle 5, die mit einer einwindigen Wendel versehen ist, abgetastet.When using the proposed method, the contour of the inner surface of the pipe becomes in the weld seam area (9) immediately after deburring with a helical Sensing roller 5, which is provided with a single-wind helix, is scanned.

Die Differenzbewegung "st der Abtastrolle 5 zum am Rohrkörper angebrachten Gehäuse 2 wird in elektrische Signale umgewandelt. Diese Meßergebnisse, d.h. Meßwert 12 und Normalkontur werden auf einem Oszillator angezeigt oder durch einen Schreiber aufgezeichnet und stellen die Rohrinnenkontur dar; ferner können die Meßergebnisse direkt zur Nachsteuerung einer motorisch verstellbaren Schweißrolle 13 gegenüber einer vorzu#ustierenden Schweißrolle 14 oder des Entgraters benutzt werden.The differential movement "st of the follower roller 5 to that attached to the pipe body Housing 2 is converted into electrical signals. These measurement results, i.e. measured value 12 and normal contour are displayed on an oscillator or by a recorder recorded and represent the inner contour of the pipe; furthermore, the measurement results directly for readjustment of a motorized adjustable welding roller 13 opposite a welding roller 14 or the deburring tool to be pre-set can be used.

Mit Hilfe der Vorrichtung können schnelle Änderungen als Grenzwertüberwachung zur Anzeige gebracht werden.With the help of the device, rapid changes can be made as limit value monitoring be brought to the display.
