Description

Anmeldung zum Patent einer Schutzvorrichtung mit Augenschutz und Spanauswurf ftlr Universaloberfräsen Die zur Patenterteilung vorgelegte Schutzvorrichtung ist das Produkt langer Überlegungen und Versuche, die auf einen schweren Betriebsunfall mit einer Oberfräse erfolgten.Application for a patent for a protective device with eye protection and chip ejection ftlr universal routers The protective device submitted for patent is the product of long deliberations and trials leading to a serious industrial accident with a router.

Nach Aussagen des Gewerbeaufsichtsbeamten sind die bestehenden Schutzvorrichtungen unzureichend. Durch die Konstruktion und Arbeitsweise der Oberfräsen war eine völlige Sicherheit bisher nicht möglich.According to the labor inspectorate, the existing protective devices are in place insufficient. Due to the design and operation of the routers it was a complete one Security not yet possible.

Durch diese Neuentwicklung dürften künftige Unfälle beim Freihandfräsen verhindert werden, da 1. das Fräswerkzeug abgedeckt ist 2. keine Splitter Handverletzungen verursachen können 3. die Späflanur in eine kontrollierte Richtung ausgeworfen werden 4. weitgehende Verhinderungen von Augenverletzungen durch die Plexiglasabdeckung 5. keine Sichtbehinderung beim Fräsvorgang durch Pleyiglasabdeckung Arbeitsweise der Schutzvorrichtung Die Schutzvorrichtung wird mittels zweier Rundstäbe und zweier Klemmschrauben am Maschinengehäuse befestigt. Das Fräsmesser wurd auf die zu fräsende Tiefe eingestellt und die Schutzvorrichtung so eingestellt, daß das zu bearbeitende Werkstück gerade darunter durchgefwirt werden kann, Beim Fräsen entsteht automatisch in der oberen und unteren runden Öffnung ein Sog, der die in diesem Bo Wch anfallenden Späne in das Innere des Gehäuses saugt.This new development is likely to cause future accidents during freehand milling prevented because 1. the milling tool is covered 2. no splinters hand injuries 3. the Späflanur can be ejected in a controlled direction 4. extensive prevention of eye injuries through the plexiglass cover 5. No visual obstruction during the milling process due to the Pleyiglas cover the protective device The protective device is made by means of two round bars and two Clamping screws attached to the machine housing. The milling knife was on the to be milled Depth adjusted and the protective device adjusted so that the to be machined Workpiece just below it can be milled through, when milling occurs automatically In the upper and lower round opening there is a suction, which accumulates in this Bo Wch Sucks chips into the interior of the housing.

Der im Gehäuse durch das Rotieren des Fräsmessers entstehende Wind drück die entstehenden und hereingesaugten Späne an die Innenwand.The wind generated in the housing by the rotation of the cutter blade press the chips that are created and sucked in against the inner wall.

Durch den fliehenden Charakter der schneckenartig verlaufenden Sontur werden die Späne mit wachsender Geschwindigkeit aus dem Absaugstutzen gedrückt. Bei Verwendung von Fräsern kleiner Durchmesser kann ein Absaugschlauch mittels eines Klemmrings befestigt werden.Due to the fleeing character of the snail-like Sontur the chips are pressed out of the suction nozzle with increasing speed. When using cutters with a small diameter, a suction hose can be removed by means of a Clamping ring are attached.

Die Plexiglasscheibe an der Oberseite des Gehäuses bleibt durch die Luftbewegung im Inneres des Gehäuses stets sauber, kann aber bei evtl. Beschmutzungen durch Lösen zweier Schrauben gereinigt werden.The plexiglass on the top of the case stays through the Air movement inside the housing is always clean, but can if it is dirty can be cleaned by loosening two screws.
