Betreff: Beschreibung des Winkel-Entgraters. Subject: Description of the angle deburrer.

Der Winkel-Entgrater dient zur Entgratung oder Versenkung von Bohrungen oder sonstigen Materialdurchbrechungen an den Innenseiten von Metallziehteilen oder U-förmig gebogenen Blechteilen oder sonstigen an der Oberfläche un-· handlichen Materialteilen.The angle deburrer is used to deburr or countersink holes or other material openings the inside of drawn metal parts or U-shaped bent sheet metal parts or other un- handy material parts.

Dieser insbesondere in blechverarbeitenden Werkstätten häufig auftretende Arbeitsgang wurde bisher entweder in unrationeller Weise von Hand mit der Peile ausgeführt oder aber mit Hilfe der bekannten Winkelbohrmaschinen vorgenommen.This operation, which occurs frequently in sheet metal processing workshops, was previously either in Inefficiently carried out by hand with the Peile or with the help of the well-known angle drills performed.

Die technische Aufgabe des Gerätes besteht darin, an Ziehteilen, Blechteilen oder sonstigen Materialteilen deren Oberfläche wegen der Form des Arbeitsteiles einer herkömmlichen Bearbeitung etwa mit Bohrmaschine oder Drehbank unzugänglich ist von ,dem durch Bohrung oder sonstige Materialdurchbrechung entstandenen Materialrückstand (G-rat) zu säubern (entgraten) und die Bohrungsränder abzuschrägen (versenken). Durch die bisher üblichen Hilfsmittel, konnte dies nur in unzulänglicher Weise geschehen. The technical task of the device is to work on drawn parts, sheet metal parts or other material parts the surface of which, because of the shape of the working part, requires conventional machining, for example with a drill or The lathe is inaccessible from the material residue created by drilling or other material breakthroughs (G-rat) to clean (deburr) and bevel (countersink) the hole edges. Through the usual Aid, this could only be done inadequately.

Die Entgratung mit der Peile ist unrationell und bietet außerdem die Gefahr einer Oberflächenschädigung. Die Anwendung der verschiedenen Modelle von Winkelbohrmaschinen ist einerseits höchst aufwendig, zum anderen durch die Unhandlichkeit dieser Geräte erschwert und bei kleineren Normteilen unmöglich.Deburring with the bearing is inefficient and offers also the risk of surface damage. The application of the various models of angle drilling machines is on the one hand extremely complex, on the other hand it is difficult due to the unwieldiness of these devices and with smaller ones Standard parts impossible.

Der Winkelentgrater löst diese Aufgabe in iadealer Weise. Angeschlossen an die Arbeitswelle einer beliebigen Bohrmaschine (Hand-, Tisch-, Säulenbohrmaschine) oder Drehbank gibt er die -Möglichkeit mit diesen Geräten "über Eck" auch an unhandlichen Materialteilen jeder Größe zu entgraten und zu versenken.The angle deburrer solves this task in an ideal way. Connected to the output shaft of any drilling machine (hand, table, column drilling machine) or lathe he also gives the option of "cornering" these devices deburring and countersinking unwieldy material parts of any size.

Claims

V = MnUZZ KG METALLARBEITEN 8 Munich 8, Ampfingstraße 27 Here the drive spindle is clamped into any drilling machine or lathe. By means of a power transmission element, e.g. chain drive 3, 5, the rotary movement is transmitted to the work spindle 1 which is firmly connected to the tool and which is mounted eccentrically from the drive spindle 7 on a body 4 which is elongated from solid material. This body, the shape of which can be adapted to the respective operation, is protected by a screwed cover box. The advantage of the device compared to the previous way of working is manifold. The extremely flat design, which can also be varied according to the requirements of the respective work process, enables the device to be used for almost all bent parts and drawn parts, including workpieces that were difficult or difficult to process with the previous aids due to their complicated design Circumstances was possible. The device is far more efficient in terms of acquisition and operation than the tools that have been used up to now. Protection claims. Angle deburrer, characterized by

1) Transmission of the rotary movement of a drive spindle (7) to one that is eccentrically supported by the drive spindle,

working spindle (1) acting in the same working direction by means of a force transmission element, e.g. by means of Chain drive (3, 5).

2) Locking of the device by means of mechanical fastening on the drive unit e.g. by means of a stop rod (6).

3) storage of the force-transmitting element on a elongated body (4) held flat and adapted to the respective operation and made of any material from suitable resistance (cast aluminum, steel or plastic).

4) Covering of the force-transmitting element by a cover box (2) that can be removed for assembly and maintenance.
