Description

Klemmstahlhalter Die Erfindung betrifft einen Klemmstahlhalter mit einer Schneidplatte und einer Spanformplatte, die eine Ablenkfiäche fflr die gebildeten Späne aufweist. Clamping steel holder The invention relates to a clamping steel holder a cutting insert and a chipboard forming a deflecting surface for the formed Has chips.

Bei den bekannten Klemmstahlhaltern der eben angeführten Art fronmt es häufig vor, daß Späne zwischen E;panform- und Schneidplatte gelangen. Hiedurch werden oft Betriebstullserbrechungen und Pehler am bearbeiteten Werksttlck verursacht, Der ERfindung liegt die Aufgabe zugrunde die eben erwähnten Nachteile zu vermeiden, d.h. einen Klemmstahlhalter zu achaii fen, bei dem die gebildeten Späne nicht zwischen Spanform-und Schneidplatte gelangen können. Erfindungsgemäß wird dies bei einem Klemmstahlhalter der eingangs genannten Art dadurch erreicht, daß die sich an die wirksame Schneidkante anschließende Spanfläche der Schneidplatte durch eine im Mittelbereich der Schneidplatte vorgesehene Nut unterbrochen ist, in welche die Ablenkfläche der Spanformplat te hineinreicht.In the known clamping steel holders of the type just mentioned fronmt it often happens that chips get between E; panform- and cutting plate. Because of this Often operational breaks and faults are caused on the machined workpiece, The invention is based on the task of avoiding the disadvantages just mentioned, i.e. to achaii fen a clamping steel holder, in which the chips formed are not between Chip form and insert can get. According to the invention, this is a Clamping steel holder of the type mentioned achieved in that the effective cutting edge adjoining rake face of the cutting insert through a central area the cutting plate provided groove is interrupted, in which the deflecting surface of the Chipboard reaches into it.

Weitere Einzelheiten des gegenständlichen Klemmstahlhalters gehen aus der nachfolgenden Beschrelbung eines Ausführungsbeispiels hervor, das in der zeichnung schematisch abgebildet ist. Diene zeigt den betreffenden Klemmstahlhalter teils in Ansicht, teils im Schnitt Die aus Hartmetall bestehende Schneidplatte 1 liegt auf der am Schaft 6 mittels des Rohrstiftes 5 befestigten Auflageplatte 4 auf. Auf der der Auflageplatte 4 abgewandten Seite der Schneidplatte 1 befindet sich die eine schräge, zur Ablenkung der gebildeten Späne dienende Fläche 7' aufweisende Spanformplatte 7.For more details of the clamp steel holder in question, go to from the following description of an embodiment that is shown in the drawing is shown schematically. Diene shows the relevant clamping steel holder partly in view, partly in section The carbide insert 1 rests on the support plate 4 fastened to the shaft 6 by means of the tubular pin 5 on. Located on the side of the cutting plate 1 facing away from the support plate 4 the surface 7 'which is inclined and serves to deflect the chips formed Chipboard 7.

Dieselbe wird mit hilfe der Spannpratze 8 und der durch diese hindurchgehenden, einen Innensechskant 11 aufweisenden Spalmschraube 10 an die Schneidplatte 1 angepreßt. Die Span£ormplatte 7 ist mittels des Senkkerbnagels 9 an der Spannpratze 8 befestigt. Uni ungleichmäßige Pressungen zwischen Spanformplatte 7 und Schneidplatte 1 mit Sicherheit zu vermeiden, ist die im Mittelbereich der Schneidplatte 1 vorgesehene Nut 2 so bew messen, daß die panformplatte 7 lediglich an der der wirksamen Schneidkante 1' abgewandten Flunke der Schneidplatte 1 anliegt.The same is done with the help of the clamping claw 8 and the a socket head screw 10 having a hexagon socket 11 is pressed onto the cutting insert 1. The chipboard 7 is fastened to the clamping claw 8 by means of the countersunk nail 9. Uni uneven pressures between chipboard 7 and insert 1 with Safety is to be avoided in the central area of the cutting insert 1 Measure groove 2 so that the panform plate 7 only on the effective cutting edge 1 'facing away fluke of the cutting tip 1 is applied.

Die 3chneidplatta 1 ist auch auf ihrer der iuflageplatte 4 zugekehrten Seite mit einer Aussparung 3 versehen, da es sich bei dieser Schneidplatte 1 um eine Wendeschneidplatte handelt. Gemäß der Erfindung reicht die Ablenkfläche 7' der Spanformplatte 7 in dLe Nut 2 hinein.The cutting plate 1 is also facing the support plate 4 on its side Side provided with a recess 3, since this cutting insert 1 is an indexable insert. According to the invention, the deflecting surface 7 'extends the chipboard 7 into the groove 2 into it.

Gegenüber den bekannten Klemmstahlhaltern der eingangs genannten Art bietet der erfindungsgemäße Klemmstahlhalter den sehr wesentlichen Torteil, daß bei ihm ein Eindringen von Spänen zwischen Spanform- und Schneidplatte mit Sicherheit vermieden wird. Überdies werden bei dem gegenständlichen Klemmstahlhalter unerwünschte ungleichmäßige Pressungen zwischen der Schneidplatte und den an ihr anliegenden zeilen des Klemmstahlhalters mit Sicherheit v2rmieden.Compared to the known clamping steel holders of the type mentioned above the clamping steel holder according to the invention offers the very essential gate part that with him a penetration of chips between the chip forming and cutting insert with certainty is avoided. Moreover, in the case of the clamp steel holder in question, they are undesirable uneven pressures between the cutting plate and the one resting on it Avoid lines of the clamping steel holder with certainty.
