Description

  

      Vorrichtung    zum     Anfasen    von Rohrenden    Vorliegende Erfindung bezieht sich auf eine Vor  richtung zum     Anfasen    von Rohrenden mit einem       Fräskopf,    der durch eine axial verschiebbare Spindel  auf das gegen Drehung gesicherte Rohr zu bewegbar  ist.  



  In     Rohradjustageanlagen    werden die aus einem  Walzwerk oder einer     Zieherei        kommenden    Rohre  zunächst     gerichtet    und anschliessend in Handelslängen  unterteilt. Da die Schnittflächen der     Rohrenden    nicht       gratfrei    sind und ein Teil der Rohre an beiden Enden  mit einem     Gewinde    versehen     werden    müssen, ist  es     erforderlich,    die Enden zu entgraten und     anzufa-          sen.     



  Bei den bekannten Vorrichtungen zum     Anfasen     der Rohrenden ist der     Fräskopf    fest mit einer axial  beweglichen Spindel verbunden, durch die er auf  das Rohrende zu bewegt werden kann. Da aber  die Enden der Rohre beim     Richtvorgang    nicht ab  solut gerade werden und, somit dem     Fräskopf    nicht  axial gegenüberliegen, ist ein wünschenswertes     An-          fasen    der Rohrenden nicht gegeben.

   Man: hat diesen  Nachteil bisher in Kauf     genommen.    Betriebserfah  rungen     haben    jedoch gezeigt, dass die     aussermittig          angefasten    Rohre     dein    Ansprüchen     nicht    genügen.  Um     diesen    Nachteil zu vermeiden, wird nach der  Erfindung vorgeschlagen, den     Fräskopf    raumbeweg  lich mit der Spindel zu verbinden.  



  Zur Verbindung des     Fräskopfes    mit der Spindel       kann    eine bekannte     Gelenkwelle        Verwendung    finden,  die sich über elastische Mittel an einer die Gelenk  welle umgebenden     Hülse    abstützen kann.  



  Anhand der Zeichnung, die schematisch ein Aus  führungsbeispiel der Erfindung zeigt, sind deren Ein  zelheiten     nachstehend    näher erläutert:  Mit 1 ist eine Spindel bezeichnet, die durch nicht  dargestellte Mittel im Sinne des Pfeiles 2 axial ver-    schiebbar     sowie    drehbar in dem Gehäuse 3 gelagert  ist. Der     Fräskopf    4 ist durch eine Gelenkwelle 5  raumbeweglich mit der Spindel 1 verbunden und       stützt    sich über     elastische        Mittel    6 an     einer    Hülse 7  ab, die die     Gelenkwelle    5     dichtend    umgibt.

   Zur Bil  dung eines geschlossenen     Schmiermittelraumes    ist an  der Stirnseite 7a der Hülse 7 eine Dichtung 8 ein  gelassen. Das     elastische        Mittel    6 wirkt schwingungs  dämpfend. Das Ende 9a des durch nicht dargestellte  Mittel gegen Drehung     gesicherten    - Rohres 9 kann  dadurch auch dann von dem     Fräskopf    4     erfasst    wer  den, wenn es geringfügig gekrümmt ist,

   dem     Fräs-          kopf    4 also nicht axial     gegenübersteht.            Ein.    nach der Erfindung gelagerter     Fräskopf    kann  vorteilhaft auch bei den     sogenannten    rotierenden  Fräsmaschinen angewandt werden, bei denen die  Rohre auf einem Kreisbogen an den     Fräsköpfen     vorbeigeführt werden.



      Device for chamfering pipe ends The present invention relates to a device for chamfering pipe ends with a milling head which can be moved towards the pipe secured against rotation by an axially displaceable spindle.



  In tube adjustment systems, the tubes coming from a rolling mill or a drawing mill are first straightened and then divided into commercial lengths. Since the cut surfaces of the pipe ends are not free of burrs and some of the pipes have to be provided with a thread at both ends, it is necessary to deburr and bevel the ends.



  In the known devices for chamfering the pipe ends, the milling head is firmly connected to an axially movable spindle, by means of which it can be moved towards the pipe end. However, since the ends of the pipes do not become absolutely straight during the straightening process and therefore do not face axially opposite the milling head, the pipe ends do not have a desirable bevel.

   Man: So far, this disadvantage has been accepted. However, operating experience has shown that the off-center chamfered pipes do not meet your requirements. To avoid this disadvantage, it is proposed according to the invention to connect the milling head raummobil Lich to the spindle.



  To connect the milling head to the spindle, a known articulated shaft can be used, which can be supported by elastic means on a sleeve surrounding the articulated shaft.



  With the aid of the drawing, which schematically shows an exemplary embodiment of the invention, the details thereof are explained in more detail below: 1 denotes a spindle which is mounted in the housing 3 so as to be axially displaceable and rotatable in the direction of arrow 2 by means not shown . The milling head 4 is connected in a spatially movable manner to the spindle 1 by a cardan shaft 5 and is supported via elastic means 6 on a sleeve 7 which surrounds the cardan shaft 5 in a sealing manner.

   To form a closed lubricant space, a seal 8 is left on the end face 7a of the sleeve 7. The elastic means 6 has a vibration-damping effect. The end 9a of the pipe 9, which is secured against rotation by means not shown, can thereby also be grasped by the milling head 4 if it is slightly curved,

   the milling head 4 is not axially opposite. One. Milling head mounted according to the invention can advantageously also be used in the so-called rotating milling machines in which the tubes are guided past the milling heads on an arc of a circle.
