Description

       

  Als Handschutz ausgebildete Späneabführvorrichtung für hochtourige Fräsmaschinen.    Die vorliegende Erfindung bezieht sich  auf eine Späneabführvorrichtung für hoch  tourige Fräsmaschinen mit Stirnfräser, z. B.  für die Holz- und Weichmetallbearbeitung,  und besteht     darin,    dass eine profilierte Hülse  vorgesehen ist, die an der     Fräsmaschine    der  art montiert werden kann, dass sie als Hand  schutz das Werkzeug seitlich und hinten um  schliesst und die Frässpäne in einer einstell  baren Richtung wegleitet, unabhängig von  ,der Vorschubrichtung des Werkstückes in  bezug auf das Fräswerkzeug. Damit können  die Späne z. B. einer Absaugvorrichtung oder  einem Spänesack zugeführt werden, zwecks  ihrer Weiterverwendung (insbesondere bei  Bearbeitung von Blei und Zink).  



  Fig.1 und 2 der Zeichnung zeigen. als: Aus  führungsbeispiel der Erfindung eine Späne  abführvorrichtung an einer Fräsmaschine zum  Fräsen von Klischeeuntersätzen in -der Ste  reotypie.  



  Wie Fig. 1 und 2 veranschaulichen, be  sitzt die Späneabführvorrichtung eine profi  lierte Hülse 1 mit einem     Stiel    1a, der     mittels     einem auf der Frässpindel 3 drehbaren Hal  ter an der nicht weiter dargestellten Fräs  maschine montiert ist. Die Hülse umschliesst  den dreischneidigen Stirnfräser 2, einen       Handschutz    bildend, seitlich und hinten und  weist an diesem Teil ein Loch auf, durch das  der Fräserschaft mit geringem Spiel hin  durchtritt.

   Dieser knappe Durchgang soll in  erster Linie verhüten, dass die Messerschnei-    den des     Werkzeuges    an der Aussenwand der  Hülse streifen und sich vorzeitig abnützen,  indem bei eventueller exzentrischer Montage  der Hülse vorerst .der Werkzeugschaft mit  der Hülse in Kollision kommt; in zweiter  Linie, um zu verhüten, dass Späne zwischen  Hülse und Schaft aus .dem Loch heraus- und  dann nach allen' Seiten     fortgeschleudert     werden.  



  Die drehbare Lagerung der Späneabführ  vorrichtung an der Frässpindel 3, ermöglicht,  die Späneaustrittsöffnung der Hülse zu ver  stellen und damit die Richtung, in der die  Späne weggeleitet werden, unabhängig von  der Vorschubrichtung des Werkstückes ' in  bezug auf das Fräswerkzeug zu verändern.  



  Die     Befestigungsschraube    5 des. Stielhal  ters     gestattet    die genaue     axiale        Einstellung     der Hülse.



  Chip removal device designed as hand protection for high-speed milling machines. The present invention relates to a chip removal device for high-speed milling machines with end mills, for. B. for wood and soft metal processing, and consists in that a profiled sleeve is provided that can be mounted on the milling machine in such a way that it closes as a hand protection the tool to the side and back and the milling chips in an adjustable ble direction diverts away, regardless of, the feed direction of the workpiece with respect to the milling tool. So that the chips z. B. be fed to a suction device or a chip bag for the purpose of their further use (especially when machining lead and zinc).



  Figures 1 and 2 of the drawing show. as: From an exemplary embodiment of the invention, a chip removal device on a milling machine for milling cliché bases in the stereotype.



  As Fig. 1 and 2 illustrate, be the chip removal device sits a profiled sleeve 1 with a handle 1 a, which is mounted on the milling machine by means of a rotatable on the milling spindle 3 Hal ter on the milling machine, not shown. The sleeve encloses the three-edged end mill 2, forming a hand guard, on the side and back and has a hole on this part through which the cutter shank passes with little play.

   This tight passage is primarily intended to prevent the knife edges of the tool from grazing the outer wall of the sleeve and wearing out prematurely, as the tool shank first comes into collision with the sleeve in the event of an eccentric assembly of the sleeve; Secondly, in order to prevent chips from being thrown out of the hole between the sleeve and the shaft and then hurled off in all directions.



  The rotatable mounting of the chip removal device on the milling spindle 3 makes it possible to adjust the chip outlet opening of the sleeve and thus change the direction in which the chips are directed away, regardless of the feed direction of the workpiece 'with respect to the milling tool.



  The fastening screw 5 of the. Stielhal age allows the precise axial adjustment of the sleeve.

PATENTANSPRUCH: Späneabführvorrichtung für hochtourige Fräsmaschinen mit Stirnfräser, gekennzeich net durch eine profilierte Hülse, die an der Fräsmaschine derart montiert werden kann, dass sie als Handschutz das Werkzeug seit lich und hinten umschliesst und die Fräs- späne in einer einstellbaren Richtung weg leitet, unabhängig von der Vorschubrichtung des Werkstückes in bezug auf das Fräswerk- zeug, damit dieselben zum Zwecke ihrer Weiterverwendung einer Spänesammelvor- ri.chtung zugeführt werden können. PATENT CLAIM: Chip removal device for high-speed milling machines with face milling cutters, characterized by a profiled sleeve that can be mounted on the milling machine in such a way that it encloses the tool at the side and back as hand protection and guides the milling chips away in an adjustable direction, regardless of the feed direction of the workpiece in relation to the milling tool so that the same can be fed to a chip collecting device for the purpose of further use.
