Description

Vorliegende Erfindung betrifftGewindesehneidkluppen mit vieleckigen, mehrere Schneidstellen aufweisenden Schneidbacken, die außerhalb des an einer Breitseite offenen Kluppenrahmens um Schraubenbolzen in die neue Lage gedreht werdten. The present invention relates to thread cutting dies having polygonal, multiple cutting locations having cutting jaws around the outside of the clip frame that is open on one broad side Screw bolts are turned into the new position.

Das Neue besteht darin, daß die Backen einerseits unter Wirkung von Federn stehen, die die fest angeordneten Schraubenbolzen umgeben, ίο anderseits sich gegen Muttern der Schraubenbolzen legen, so daß beim Lösen der Muttern die Backen selbsttätig aus dem Kluppenrahmen heraustreten.The novelty is that the jaws are on the one hand under the action of springs that the Surrounding fixed screw bolts, ίο on the other hand against the nuts of the screw bolts place so that when loosening the nuts the jaws automatically out of the clip frame stepping out.

Auf der Zeichnung ist die neue Schneidlduppe in einer Ausführungsform dargestellt, und zwar zeigt:In the drawing, the new cutting dome is shown in one embodiment, namely shows:

Abb. ι dieselbe in einer Ansicht undFig. Ι the same in a view and

Abb. 2 in einem Schnitt nach A-A der Abb. 1.Fig. 2 in a section along AA of Fig. 1.

Es ist α der Kluppenrahmen, in dessen Öffnung b die beiden vieleckigen Schneidbacken c, d geführt sind. Der letztere der beiden ruht auf der Deckfläche eines mit der Stellschraube e verbundenen Druckstückes f und legt sich mit seinen hinteren Flächen gegen den entsprechend winklig geformten Ausschnitt derselben, so daß die im gegebenen Beispiel sechseckige Schneidbacke von vier Seiten begrenzt wird.It is α the clip frame, in the opening b of which the two polygonal cutting jaws c, d are guided. The latter of the two rests on the top surface of a pressure piece f connected to the adjusting screw e and lies with its rear surfaces against the correspondingly angled cutout of the same, so that the hexagonal cutting jaw in the example given is limited on four sides.

In gleicher Weise ist die Gegenbacke c vierseitig begrenzt und ruht auf einer unten am Rahmen befestigten Platte g, welche mit einer von einer Druckfeder h umgebenen festen Schraube i ausgerüstet ist, auf welche die Backe aufgesteckt ist, die mittels einer Mutter k auf der Unterlegplatte g des Rahmens festgespannt wird.Similarly, the counter-jaw is c quadrilateral limited and rests on a fixed bottom of the frame plate g, which is equipped i to one of a compression spring h surrounded solid screw on which the jaw is mounted, the k by means of a nut on the shim g of the frame is clamped.

In gleicher Weise wird die unter Wirkung einer Feder i stehende Einsatzbacke d mittels einer auf der Schraube m sitzenden Mutter η auf der Unterlage g des beweglichen Druckstückes f festgespannt. Das Umsetzen der Schneidbacken c, d erfolgt in einfacher Weise durch Lösen der Muttern k, n, wonach die Backen durch die in ihrer Bohrung φ bzw. φ1 liegenden Druckfeder h bzw. I selbsttätig angehoben (Abb. 2) und dann bis zur nächsten Schneidstelle gedreht werden, worauf die Muttern wieder angezogen und die Backen festge-■ spannt werden.In the same way, the insert jaw d , which is under the action of a spring i , is tightened on the base g of the movable pressure piece f by means of a nut η sitting on the screw m. The cutting jaws c, d are moved in a simple manner by loosening the nuts k, n, after which the jaws are automatically lifted by the compression spring h or I located in their bore φ or φ 1 (Fig. 2) and then to the next Cutting point are rotated, whereupon the nuts are tightened again and the jaws are clamped.
