Description
Die Erfindung betrifft eine Vorrichtung zur automatischen Kontrolle und/oder Steuerung des Entgratungs-Werkzeugs und/oder der Schweißrollen beim HF-Längsnahtschweißen von Rohren gemäß dem Gattungsbegriff. The invention relates to a device for automatic Control and / or control of the deburring tool and / or the welding rollers in HF longitudinal seam welding of pipes according to the generic term.
Die Entgratungskontrolle wurde bisher visuell durch das Bedienungspersonal vorgenommen. Die Kontrolle konnte hierbei erst am abgetrennten Rohr und somit zu spät durchgeführt werüen. BcL der kontinuierlichen Rohrherstellung wurde dL· Fertigung von Zeit zu Zeit unterbrochen und ein Fenster aus lern Rohr herausgebrannt und durch dieses mit Spion die Entgratkontrolle vorgenommen. Hierbei entstand nicht nur der zeitliche, sondern auch ein materieller Produktionsverlust.The deburring control was previously carried out visually by the operating personnel. The control could only be carried out on the severed pipe and therefore too late. BcL of continuous Pipe production was interrupted from time to time and a window was burned out of the pipe and made the deburring control through this with spy. Not only the temporal, but also a material loss of production.
Bekannt ist auch eine Überprüfung der Innenentgratung mittels Ultraschall. Nachteilig bei diesen Verfahren ist, daß die Prüfaussage undifferenziert bezüglich der verschiedenen Entgratungsfehler ist. Ein Erkennen sämtlicher Entgratungsfehler ist mit der Ultraschailübcrprüfung nicht möglich.A check of the internal deburring is also known by means of ultrasound. The disadvantage of this method is that the test statement is undifferentiated with regard to the various deburring defects. A detection of all deburring errors is with the ultrasonic check not possible.
Aufgabe der Erfindung ist, eine Vorrichtung zu schaffen, mit der unmittelbar hinter der Entgratung -15 auftretende Abweichungen von der gewünschten Normalkontur erkannt und anschließend daran umgehend behoben werden können.The object of the invention to provide a device with which immediately after the deburring - 15 occurring detected deviations from the desired contour normal and can then be fixed thereto immediately.
Zur Lösung der Aufgabe wird eine Vorrichtung vorgeschlagen, wie sie in dem Patentanspruch beschrieTo achieve the object, a device is proposed as described in the claim
n ben ist. Mit Hilfe der Anzeige der Vorrichtung lassen sich alle Fehler feststellen, zuordnen und ohne Unterbrechung der Fertigung beheben- Insbesondere braucht die Gutfertigung nicht unterbrochen zu werden, um die Entgratung zu überprüfen. n ben is. With the aid of the display of the device, all errors can be determined, assigned and corrected without interrupting production.

Wie aus Fi g. la und Ib ersichtlich, ist die Vorrichtung an einem im Innern des Rohres befindlichen und geführten Gestänge 1 in einem Gehäuse 2 angebracht. In dem Gehäuse 2 befinden sich im Winkel zur senkrechten Rohrachse Kopierrollen 3. Ferner eine mittig zu diesen angeordnete wendeiförmige 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. einem Oszillator, verbunden ist.As shown in Fig. la and Ib can be seen, is the device attached to a rod 1 located inside the pipe and guided in a housing 2. In the housing 2 there are copier rollers 3 at an angle to the vertical pipe axis central to these arranged helical scanning roller 5, which can be rotated in a movable frame 4 is stored. 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. B. an oscillator connected.
In Fig. 2 ist ein Oszillatorbild des Meßwertes 12, welcher eine fehlerhafte Kontur, z. B. Ausbruch eines Innenentgratungswerkzeuges im Vergleich zur Normalkontur, einer einwandfreien Entgratung darstellen soll.In Fig. 2 is an oscillator image of the measured value 12, which is a faulty contour, z. B. Outbreak of a Internal deburring tool compared to the normal contour, should represent a perfect deburring.
Fig.3 zeigt ein Meßschema für eine Vorrichtung mit der unten beschriebenen Nachsteuerung der Schweißrollen 13,14.3 shows a measurement scheme for a device with the adjustment of the welding rollers 13, 14 described below.
Bei Anwendung der Vorrichtung wird die Kontur der Rohrinnenoberfläche im Schweißnahtbereich 9 unmittelbar nach der Entgratung mit einer Abtastrolle 5. die mit einer einwind^gen Wendel versehen ist. abgetastet.When the device is used, the contour of the inner surface of the pipe in the weld seam area 9 becomes immediate after deburring with a scanning roller 5. which is provided with a single-wind helix. scanned.
Die Differenzbewegung »s« der im Rahmen 4 gelagerten Abtastrolle 5 zum am Rohrkörper mit Kopierrollen anliegenden Gehäuse 2 wird in elektrische Signale umgewandelt. Diese Me3ergebnisse, d. h. Meßwert 12 und Normalkontur Π. werden auf einen Oszillator angezeigt oder durch einen Schreiber aufgezeichnet und stellen die Rohrinnenkontur dar.The differential movement "s" between the scanning roller 5 mounted in the frame 4 and the housing 2 resting on the tubular body with copying rollers is converted into electrical signals. These measurement results, ie measured value 12 and normal contour Π. are displayed on an oscillator or recorded by a recorder and represent the inner pipe contour.
Ferner können die Meßergebnisse direkt zur Nachsteuerung einer motorisch verstellbaren Schweißrollc 13 gegenüber einer voi zujustierenden Schweißrolle 14 und/oder der Anstellung der Entgratungswerkzeuge 15 benutzt werden.Furthermore, the measurement results can be used directly to readjust a motorized adjustable welding roller 13 compared to a welding roller 14 to be adjusted and / or the adjustment of the deburring tools 15 can be used.
Mit Hilfe der Vorrichtung können schnelle Änderungen als Grenzwertüberwachung zur Anzeige gebracht werden.With the aid of the device, rapid changes can be displayed as limit value monitoring will.
