Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Entfernen des Innengrates an -der Längsnaht elektrisch geschweißter Röhre, bei der ein mehrere in radialer Abstufung hintereinander angeordnete, schaberartig wirkende Schneiden tragender Schaft von ernenn im Rohr geführten Halter getragen ist.The invention relates to a device for removing the Inner ridge on the longitudinal seam of electrically welded tubes, in which one several Blade-like cutting edges arranged one behind the other in radial gradation The supporting shaft is carried by the holder guided in the tube.
Bei einer bekannten Vorrichtung diesen Art .sind die Schneiden fest mit dem Schaft verbunden. Da nm Innern des Rohres wenig Platz zur Verfügung steht, müssen die Schneiden verhältnismäßig klein sein. Infolgedessen ist die Wärmeableitung von .den Schneiden ,ungenügend, so .da@B sie sich schnell und ungleichmäßig abnutzen.In a known device of this type, the cutting edges are fixed connected to the shaft. Since there is little space available inside the pipe, the cutting edges must be relatively small. As a result, the heat dissipation from .the cutting edges, insufficient, so .da @ B they wear out quickly and unevenly.
Es ist ,bereits bekannt, zum Außenbearbeiten von zyli-ndirisichen Werkstücken einen Drehstahl mit durch eine umlaufende Scheibe gebildeter Schneide zu verwenden. Dadurch wird erreicht, :daß- der arbeitende Teil der Schneide ständig wechselt; so daßeine ununterbrochene Kühlung der Schneide in ihrem jeweils unwi.rksemen Bereich stattfindet.It is already known for external machining of cylindrical Workpieces a turning tool with a cutting edge formed by a rotating disk to use. This achieves: that - the working part of the cutting edge constantly changes; so that an uninterrupted cooling of the cutting edge in its respective ineffective Area takes place.
Die Erfindung ?bezweckt die Nutzbarmachung dieses Gedankens für die Vorrichtung der eingangs bezeichneten Art. Das Neue besteht darin, daß- der Schaft exzentrisch und drehbar -im Halter gelagert ist und im Durchmesser albgestufte Scheiben trägt, ,deren Umfangsflächen die Schneiden b,il@d@en. Da die Schneiden mit ständig wechselnden Abschnitten zur Witkunig kommen, wird eine ungleichmäßige Abnutzung der Schneiden *und damit eine nachteilige Veränderung der Durch.mes.serab.stufungvermieden. Dia außerdem eine gute Wärmeabführung gewährleistet ist, die nötigenfalls noch durch eine in das Rohr eingeführte Kühlflüssigkeit erhöht werden kann, wird eine bedeutend, längere Standzeit des gesamten Werkzeuges.-erziielt als. bei der bekannten Vorrichtung. Die exzentrische .Anordnung der Schneiden hat den Vorteil, daß- unter dem Werkzeug in @dcm Roihr -ein-genügend großer Zwischenraum verbleibt, so daß die Späne durch das-. sich vorschiebende Rohr mitgenommen werden können. - -Ein Ausführungsbeispiel ist= n=-der- Zeichnung dargestellt. _ Abb. i zeigt die Vorrichtung und das zu entgratende Rohr im -Längsschnitt; Abb. a, 3 und 4 zeigenden Querschnitt nach den Linien A-A b@zw. B-B bzw. C-C .der Abb. i.The aim of the invention is to utilize this idea for the device of the type mentioned at the beginning. What is new is that the shaft is eccentrically and rotatably mounted in the holder and has disks stepped in diameter, the circumferential surfaces of which have the cutting edges b, il @ d @en. Since the cutting edges come to the point with constantly changing sections, uneven wear of the cutting edges * and thus a disadvantageous change in the diameter gradation is avoided. Since, in addition, good heat dissipation is guaranteed, which if necessary can be increased by a cooling liquid introduced into the tube, a significantly longer service life of the entire tool is achieved. in the known device. The eccentric arrangement of the cutting edges has the advantage that there remains a sufficiently large gap under the tool in the pipe, so that the chips can pass through. advancing pipe can be taken. - -An embodiment is shown = n = -the drawing. _ Fig. I shows the device and the pipe to be deburred in longitudinal section; Fig. A, 3 and 4 showing cross-section along the lines AA b @ zw. BB or CC. Of Fig. I.
Die zum Entfernen des Innengrates des elektrisch geschweißten Rohres i dienende Vorrichtung hestht in,der Hauptsache aus einem in dem Rohr durch- Rollen a, 3, 4, 5 geführten Halter 6, dem exzentrisch und drehbar in denn Halter gelagerten Schaft 8 und dem von dem Schaft 8 außerhalb des Halters 6 .getragenen Werkzeug 7, welches die im Durchmesser abgestuften Schneiden 7" aufweist. Das Werkzeug 7 kann aus einzelnem, die Sahneeiden aufweisenden Scheiben zusammengesetzt oder aus einem Stück hergestellt mein. Der Schaft 8 ist mit einer Antrieb@s-wellie 9 verbunden, die durch ein Getriebe fo, ii in- Drehung versetzt wird. In axi!alier Richtung ist@das Werkzeug einerseits durch eine Schaftverdickung und andererseits :durch die Antriebswelle 9 gegen denn Halter 6 abgestützt.The device used to remove the inner ridge of the electrically welded pipe i is mainly composed of a holder 6 guided in the pipe by rolling a, 3, 4, 5, the eccentric and rotatable shaft 8 mounted in the holder and that of the The tool 7 is carried outside the holder 6 and has the cutting edges 7 ″ which are graduated in diameter. The tool 7 can be composed of individual discs containing the cream silk or made from one piece. The shaft 8 is equipped with a drive @ s- Wellie 9, which is set in rotation by a gearing fo, ii. In the axial direction, the tool is supported on the one hand by a thickened shaft and on the other hand by the drive shaft 9 against the holder 6.
In, das Rohr kann eine Kühlflüssigkeit eingeleitet werden, .in welche die umlaufenden Schneiden 7a eintauchen.A cooling liquid can be introduced into the tube, into which the circumferential cutting edges 7a are immersed.
