Description

Vorrichtung zum Entfernen des Innengrates längsnahtgeschweißter Rohre Die Erfindung betrifft eine Vorrichtung zum Entfernen des Innengrates längsnahtgeschweißter Rohre und bedient sich in bekannter Weise eines am Kopf eines in Richtung der Rohrachse bewegbaren Gestänges angebrachten Abgratwerkzeugs. Erfindungsgemäß besteht der Kopf aus einer in mehrere Segmente symmetrisch längs geschlitzten, kegeligen Hülse, deren eines oder mehrere Segmente das oder die Abgratwerkzeuge, z. B. das Schneidwerkzeug oder die Walzrolle oder die Drückwerkzeuge, tragen, und einem in die Hülse eingepaßten kegeligen Dorn zum radialen, elastischem Ausstellen der Segmente. Zum Hineinziehen des Dornes in die Hülse ist eine Feder, vorzugsweise eine Tellerfeder, vorgesehen.Device for removing the inner ridge of longitudinally welded pipes The invention relates to a device for removing the inner ridge of longitudinally welded seams Pipes and uses in a known manner one at the head of one in the direction of the pipe axis movable rod attached trimming tool. According to the invention, there is the head from a conical sleeve, symmetrically slit longitudinally in several segments, whose one or more segments that or the trimming tools, e.g. B. the cutting tool or the roller or the spinning tools, and one fitted into the sleeve conical mandrel for radial, elastic exposure of the segments. To pull in of the mandrel into the sleeve, a spring, preferably a plate spring, is provided.

Durch diese Ausbildung wird in einfacher und verschleißsicherer Weise eine genau arbeitende Vorrichtung zum Entfernen des Innengrates geschaffen.This training is in a simple and wear-resistant manner created an accurate device for removing the inner ridge.

Die Zeichnung zeigt eine Ausführungsform einer Vorrichtung gemäß der Erfindung.The drawing shows an embodiment of a device according to FIG Invention.

Abb. 1 ist eine Seitenansicht, teilweise im Längsschnitt, einer Vorrichtung mit drei Eindrückwerkzeugen, Abb. 2 die Draufsicht nach Abb. 1, Abb. 3 der O_uerschnitt A-A und Abb. 4 der O_uerschnitt B-B nach Abb. 1.Figure 1 is a side view, partly in longitudinal section, of an apparatus with three pressing tools, Fig. 2 the plan view according to Fig. 1, Fig. 3 the O_u section A-A and Fig. 4 the O_u section B-B according to Fig. 1.

In den längsnahtges,Ghweißten Rohren 1 sind die Abgratwerkzeuge geführt. In den Abb. 1 bis 4 sind drei Eindrückwerkzeuge 2 als Abgratwerkzeuge vorgesehen. Sie sitzen lösbar auf den längs geschlitzten, kegeligen Spannhülsen 4, die mittels der angepaßten kegeligen Spanndorne 5 radial anstellbar sind. Die Spannhülsen 4 sind an den Gestängerohren 6, die Spanndorne 5 an den Rundstangen 7 befestigt. Sie sind: über die Tell-erfede@rn 8 miteinander verbunden.The trimming tools are guided in the longitudinally welded, welded tubes 1. In Figs. 1 to 4, three pressing tools 2 are provided as trimming tools. They sit releasably on the longitudinally slotted, tapered clamping sleeves 4, which by means of the adapted tapered mandrels 5 can be adjusted radially. The clamping sleeves 4 are attached to the rod tubes 6, the mandrels 5 to the rods 7. she are: connected to each other via the Tell-erfede @ rn 8.
