Description
Es ist bekannt, Schneidkörper für Zerspanungswerkzeuge so auszubilden, daß sie in der Draufsicht die Form eines Parallelogratnmes aufweisen. Um zu vermeiden, daß derartige Schneidkörper bei sehr verschiedenartigen und plötzlich sich ändernden Beanspruchungen, wie sie zum Beispiel beim Kopierdrehen auftreten, aus der Halterung herausgerissen werden, ist man dazu übergegangen, die beiden Spannflächen des Schneidkörpers so auszubilden, daß sie einen spitzen Winkel bilden, dessen Scheitel an der vom Werkzeugschaft abgewendeten Seite liegt.It is known to design cutting bodies for cutting tools so that they in plan view the Have the shape of a parallelogram. In order to avoid, that such cutting body with very different and suddenly changing loads, such as they occur, for example, during copy turning, are torn out of the holder, one has gone over to this, to form the two clamping surfaces of the cutting body so that they form an acute angle, the The apex is on the side facing away from the tool shank.
Um diese Schneidkörper in verschiedenen Lagen einsatzfähig zu machen, sie also als Wendeschneidplatten benutzen zu können, hat man auch schon daran gedacht,In order to make these cutting bodies usable in different positions, so they are used as indexable inserts to be able to use, one has already thought of

eine der beiden Spannflächen aus zwei Flächen zu bilden, die einen stumpfen Winkel miteinander einschließen. In erster Linie hat man diese beiden Flächen als Ebenen ausgebildet. Die Erfindung, durch die eine weitere Verbesserung erzielt wird, geht von der Erkenntnis aus, daß auch bei der zuletzt erwähnten bekannten Ausführungsform die Gefahr des Herausreißens des eingespannten Schneidkörpers besteht, wenn Kräfte in Richtung der Schnittgeraden wirksam sind, die von den beiden Ebenen der Einspannfläche gebildet wird.to form one of the two clamping surfaces from two surfaces, which include an obtuse angle with one another. First and foremost, you have these two areas as Levels trained. The invention, by which a further improvement is achieved, is based on the knowledge from that even with the last-mentioned known embodiment there is a risk of the clamped being torn out Cutting body exists when forces in the direction of the intersection line are effective by the two Planes of the clamping surface is formed.
Die Erfindung betrifft eine Wendeschneidplatte für ein Zerspanungswerkzeug, die in der Draufsicht die Form eines Parallelogramms aufweist und deren eine Spannfläche aus zwei Flächen besteht, die einen stumpfen Winkel miteinander einschließen. Erfindungsgemäß sind die beiden Flächen Teile von Rotationsflächen, die eine gekrümmte Schnittlinie aufweisen. Aus herausstellungstechnischen Gründen wird man Rotationsflächen wählen, die man durch ' gradlinige Erzeugende bilden kann. Die in Frage kommenden Flächenteile können also Teile von Zylinder- oder Kegelflächen sein. Zweckmäßig ist es, die Rotationsflächen so zu wählen, daß ihre Achsen nahezu senkrecht zur zentrischen Symmetrieachse des Schneidkörpers sind. Eine bevorzugte Ausführungsform besteht darin, daß die beiden Rotationsflächen eine gemeinsame Achse aufweisen.The invention relates to an indexable insert for a cutting tool which, in plan view, has the shape of a parallelogram and whose one clamping surface consists of two surfaces that form an obtuse angle include with each other. Both are according to the invention Surfaces Parts of surfaces of revolution that have a curved line of intersection. For technical reasons For reasons, one will choose surfaces of revolution, which can be defined by ' can form straight generators. The surface parts in question can therefore be parts of cylinder or Be conical surfaces. It is useful to use the surfaces of revolution to be chosen so that their axes are almost perpendicular to the central axis of symmetry of the cutting body. One preferred embodiment is that the two Surfaces of revolution have a common axis.
An Hand eines Ausführungsbeispieles wird die Erfindung näher erläutert. In den Figuren 1, 2, 3 und k der Zeichnung ist eine in einen Werkzeugkopf eingespannte erfindungsgemäße Wendeschneidplatte im Aufriß, Grundriß, Seitenriß und Schrägriß dargestellt.The invention is explained in more detail using an exemplary embodiment. In Figures 1, 2, 3 and k of the drawing, an indexable insert according to the invention clamped in a tool head is shown in elevation, plan, side elevation and oblique view.

Die erfindungsgemäße Vendeschnexdplatte 1 ruht auf der Amboßplatte 2, die in dem Kopf des Werkzeugschaftes 3 angeordnet ist. Die Wendeschneidplatte, die in der Draufsicht die Form eines Pa->> rallelogrammes aufweist, wird durch die Klemmpratze 4 in ihrer Lage fixiert. An ihrer Unterseite ist die Wendeschneidplatte mit den Auflageflä- chen 5 ausgestattet, die erfindungsgemäß Teile von Kegelflächen sind. Diese weisen eine geraeinsame Achse auf, die parallel zur Zeichenebene und senkrecht zur Symmetrieachse der Schneidplatte verläuft. Auf der Oberseite der Wendeschneidplatte 1 sind die Spanbre hernuten 6 vorgesehen sowie der Steg 7, auf den die Klemmpratze k einwirkt. Weitere Einzelheiten der Wendeschneidplatte 1 sind aus den Figuren 3 und k zu erkennen. Die Schnittlinie zwischen den beiden Rotationsflächen 5 ist im vorliegenden Falle ein Kreis, der in der Draufsicht als Gerade erscheint, die parallel zu den längeren Seiten des Parallelogramm es verläuft.The Vendeschnexdplatte 1 according to the invention rests on the anvil plate 2, which is arranged in the head of the tool shaft 3. The indexable insert, which in plan view has the shape of a parallelogram, is fixed in its position by the clamping claw 4. On its underside, the indexable insert is equipped with the bearing surfaces 5, which according to the invention are parts of conical surfaces. These have a straight axis that runs parallel to the plane of the drawing and perpendicular to the axis of symmetry of the cutting insert. On the top of the indexable insert 1, the Spanbre hernuten 6 are provided as well as the web 7 on which the clamping claw k acts. Further details of the indexable insert 1 can be seen from FIGS. 3 and k . In the present case, the line of intersection between the two surfaces of rotation 5 is a circle that appears in the top view as a straight line that runs parallel to the longer sides of the parallelogram.
