Abstract

Die Erfindung bezieht sich auf eine Werkzeugführung mit einem Gehäuse (10), in dem sich das Werkzeug (7) in Längsrichtung beweglich über zumindest einen Führungsabschnitt (11, 12) mit jeweils zumindest einem buchsenartigen Führungselement (16) und einem ebenfalls buchsenartigen Lagerbauteil (17) in Querrichtung elastisch abstützt, und das einen Anschlag (15) aufweist, welcher den Bewegungsspielraum des Werkzeugs (7) entgegen seiner Ausfahrbewegung (Pfeil 14) begrenzt. Jeweils einer der beiden zusammenwirkenden Führungsbestandteile - Führungselement (16) und Lagerbauteil (17) - weist eine kippfähige Längsfläche (16d, 17a bis d) mit einem linienhaften Scheiteldurchmesser (SP) auf, an den sich seitlich Flächenabschnitte (17c, 17d) mit davon abweichendem, sich in Längsrichtung veränderndem Durchmesser anschließen. Ferner ist die dem Werkzeug (7) zugewandte Innenfläche (16a) des Führungselements (16) - im Längsschnitt betrachtet - mit Ausnahme allenfalls ihrer stirnseitigen Endabschnitte (16b, 16c) geradlinig ausgebildet.
Mit der Erfindung wird vorgeschlagen, jeden Führungsabschnitt (11, 12) jeweils aus einem Führungselement (16) und einem Lagerbauteil (17) zusammenzusetzen, wobei das an dem Führungselement (16) anliegende Lagerbauteil (17) aus einem weicheren, elastischen Werkstoff besteht als das Führungselement (16) selbst. Die auf dem Scheiteldurchmesser liegenden Scheitelpunkte (SP) - entsprechend dem Größtdurchmesser (DG) einer kippfähigen Außenfläche (16d, 17b bis d) oder dem Kleinstdurchmesser einer kippfähigen Innenfläche (17a) - zumindest einer kippfähigen Längsfläche (17b bis d) sind bezüglich deren Erstreckung in Längsrichtung außermittig (Abstand e) angeordnet, wobei jede kippfähige Längsfläche einer im Längsschnitt im wesentlichen geradlinigen Gegenfläche (Führungselement 16, Lagerbauteil 17 bzw. Gehäuse 10) gegenüberliegt.
