Abstract

The drill provides subsequent deburring on the inside edge of the bore in a single operation. The bit body is provided with a pocket into which a spring loaded blade (A) hinged on a pivot (C) is fitted. A spring (B) fitted inside the pocket pushes the blade outwardly, so that deburring edge (G) protrudes form the bit surface. The deburring edge is horizontal continuing with rounded chamfered edge, so that during the drilling operation the blade retracts against the pressure spring into the pocket without participating in the drilling. The deburring edge protrudes just sufficiently to remove the burr and then, by action of the rounded edge, is pushed back once more into the pocket and the bit can be withdrawn.

Description

BESCHREIBUNG DESCRIPTION

Bezeichnung der Erfindung: "BOHRER ZUM BOHREN UND ENTGRATEN Anwendungsgebiet: Für alle Werkstücke die zur Zeit gebohrt und entgratet werden.Name of the invention: "DRILLS FOR DRILLING AND DEBURRING Field of application: For all workpieces that are currently being drilled and deburred.

Vorteile Bohren und entgraten in einem Arbeitsgang ohne daiS die Bohrzeit erhöht wird. Bohren bzw. entgraten von schwer zugänglichen Graten, z.B. ein Quatratrohr innen entgraten.Advantages Drilling and deburring in one operation without the drilling time is increased. Drilling or deburring hard-to-reach burrs, e.g. a square tube deburr inside.

Vorgang: Beim Bohren selbst verändert sich nichts. Sobald der Bohrer in das Werkstück eintaucht, schiebt sich der Entgrater in den Bohrer zurück. Ist das Werkstück durch bohrt, (es entsteht ein Grat) wird der Entgrater durch den Druck einer Feder aus dem Bohrer gedrückt. Nun wird der Bohrer zurückgezogen, der Entgrater schneidet den Grat ab und minimal in das Werkstück ein, wird aber durch die Rundung am Entgrater in den Bohrer zurückgedrückt. Nun kann der Bohrer ohne hindernis ganz aus dem Werkstück gezogen werden.Process: nothing changes when drilling. Once the drill dips into the workpiece, the deburrer slides back into the drill. is the workpiece is drilled through, (a burr is created), the deburrer is due to the pressure a spring pressed out of the drill. Now the drill is withdrawn, the deburrer cuts off the burr and minimally cuts into the workpiece, but is due to the rounding pressed back into the drill on the deburrer. Now the drill can go completely without hindrance be pulled out of the workpiece.
