Abstract

Ein Ausbauwerkzeug (20) zum Extrahieren von spiralförmigen Gewindeeinsätzen umfasst einen länglichen Grundkörper (23,..,26), an dessen einem Ende eine sich nach vorne zu verjüngende Ausziehspitze (28) zum einschneidenden Einführen in den zu extrahierenden Gewindeeinsatz, und an dessen anderem Ende Mittel (23) zum Drehen des Ausbauwerkzeugs (20) um die Werkzeuglängsachse vorgesehen sind.An extracting tool (20) for extracting helical threaded inserts comprises an elongate body (23, .., 26) having at one end a forwardly tapered extraction tip (28) for incisive insertion into the threaded insert to be extracted and at the other thereof End means (23) for rotating the removal tool (20) are provided around the tool longitudinal axis.

Bei einem solchen Ausbauwerkzeug wird ein Ausbau der Gewindeeinsätze durch Inspektionsöffnungen hindurch auf einfache und sichere Weise dadurch ermöglicht, dass die Ausziehspitze (28) zumindest abschnittweise die Form eines steilen Pyramidenstumpfes (28.1) aufweist.

Figure imgaf001
With such a removal tool, removal of the threaded inserts through inspection openings is made possible in a simple and secure manner by virtue of the pull-out tip (28) having the shape of a steep truncated pyramid (28.1), at least in sections.
