Abstract

To accommodate the cutting insert (6), the holder (1) is provided with a recess (2), the top side (4) of which runs at an angle to the longitudinal axis of the holder and the bottom side (3) of which runs parallel to the longitudinal axis of the holder. The recess (2) is designed as a groove (7) in the transverse direction of the holder, and the cutting insert (6) is designed as a matching tongue (8). An opening (5) is provided in the holder (1) at the end of the recess (2). With this design, reliable fastening of the cutting insert (6) in the holder (1) is obtained in a simple manner and without separate clamping means.

Description

La présente invention concerne un outil de coupe constitué d'un porte-plaquette et d'une plaquette coupante, pouvant être échangée, qui peut être fixée dans le porteplaquette sans moyen de serrage particulier. The present invention relates to a cutting tool consisting of a wafer holder and a cutting insert, exchangeable, which can be fixed in the carrier plate without particular clamping means.

Des outils de ce type pour l'écroûtage ou pour le décolletage sont connus par exemple par le modèle d'utilité No. 1 887 564 de la République Fédérale d'Allemagne et la demande de brevet publiée sous le No. 22 06 654 en
République Fédérale d'Allemagne. Ils sont toutefois encore relativement compliqués et ne conviennent pas pour des charges assez grandes.
Tools of this type for peeling or for turning are known for example by the utility model No. 1,887,564 of the Federal Republic of Germany and the patent application published under the number 22 06 654 in
Federal Republic of Germany. However, they are still relatively complicated and are not suitable for large loads.

L'invention vise un outil de coupe d'une manipulation assez simple et qui peut être fabriqué à moins de frais, tant pour ce qui concerne le porte-plaquette que la plaquette coupante elle-même. The invention relates to a cutting tool with a fairly simple handling and which can be manufactured at less cost, both as regards the wafer holder and the cutting insert itself.

Suivant l'invention, dans le porte-plaquette est ménagé un évidement dont la face supérieure est inclinée par rapport à l'axe longitudinal du porte-plaquette tandis que la face supérieure est parallèle à cet axe longitudinal du porte-plaquette, l'évidement sert suivant la direction transversale du porte-plaquette de rainure et la plaquette coupante de languette associée à cette rainure et une ouverture est ménagée dans le porte-plaquette. e
Les avantages procurés par l'invention sont no tamment le bon maintien de la plaquette de coupe dans le porte-plaquette, même pour un service assez dur, bien qu'il soit facile d'enlever la plaquette coupante du porte-plaquette.A cela s'ajoute que la plaquette coupante relativement mince peut être fabriquée à un prix favorable, ce qui est particulièrement important pour des plaquettes coupantes en métal dur.
According to the invention, in the wafer holder is formed a recess whose upper face is inclined relative to the longitudinal axis of the wafer holder while the upper face is parallel to this longitudinal axis of the wafer holder, the recess serves in the transverse direction of the groove holder and the tongue cutting insert associated therewith and an opening is provided in the insert holder. e
The advantages provided by the invention include the good maintenance of the cutting insert in the insert holder, even for a rather hard service, although it is easy to remove the cutting insert from the insert holder. In addition, the relatively thin cutting insert can be manufactured at a favorable price, which is particularly important for cutting inserts of hard metal.

Aux dessins annexés, donnés uniquement à titre d'exemple
Les figures 1, 2 et 3 sont trois vues du porteplaquette ,et
Les figures 4, 5 et 6 sont trois vues de la plaquette coupante suivant l'invention.
In the accompanying drawings, given solely by way of example
Figures 1, 2 and 3 are three views of the tray holder, and
Figures 4, 5 and 6 are three views of the cutting insert according to the invention.

Aux figures 1, 2 et 3, dans le porte-plaquette I est ménagé un évidement 2 dont la face 3 inférieure est parallèle à l'axe longitudinal du porte-plaquette 1. La face 4 supérieure de l'évidement 2 est au contraire inclinée par rapport à cet axe longitudinal, de préférence suivant un angle de 110 environ. In FIGS. 1, 2 and 3, in the insert holder I is provided a recess 2 whose lower face 3 is parallel to the longitudinal axis of the insert holder 1. The upper face 4 of the recess 2 is, on the contrary, inclined. relative to this longitudinal axis, preferably at an angle of about 110.

Dans le porte-plaquette 1 est ménagée une ouverture 5 qui assure un bon maintien en position de la plaquette 6 coupante. En outre, cette ouverture 5 sert à désolidariser la plaquette 6 coupante du porte-plaquette I, par exemple à l'aide d'une cheville en exerçant une faible action de levier. In the wafer holder 1 is provided an opening 5 which ensures a good holding in position of the wafer 6 cutting. In addition, this opening 5 serves to separate the cutting plate 6 of the wafer carrier I, for example by means of a dowel exerting a low lever action.

Dans la direction transversale du porte-plaquette, l'évidement 2 est agencé en rainure 7 et la plaquette 6 de coupe en languette 8 conjuguée de la rainure 7. In the transverse direction of the wafer holder, the recess 2 is arranged in groove 7 and the wafer 6 in tongue 8 conjugate with the groove 7.

Grâce à cet agencement à rainure et languette de la plaquette 6 coupante et du porte-plaquette 1, ainsi qu'à la face 4 supérieure de l'évidement 2 incliné par rapport à l'axe longitudinal du porte-plaquette, on obtient une fixation sûre de la plaquette 6 coupante, celle-ci pouvant être mise en place d'une manière simple et rapide et être enlevée du porte-plaquette 1 par une simple pression. With this tongue-and-groove arrangement of the cutting insert 6 and the insert holder 1, as well as the upper face 4 of the recess 2 inclined with respect to the longitudinal axis of the insert holder, a fastening is obtained. the cutting insert 6, it can be set up in a simple and fast manner and be removed from the wafer holder 1 by a simple pressure.

Les figures 4, 5 et 6 représentent la plaque 6 coupante ayant une partie éloignée de l'arête tranchante en forme de languette 8. Les angles 0 < ,A, et g sont les divers angles de dépouille nécessaires pour un outil de décolletage. Les angles ou et A sont avantageusement ménagés pour la moitié de leur valeur absolue dans le porte-plaquette 1, ce qui s'obtient par une conformation correspondante de 1 'évidement 2. Certes,la plaquette 6 coupante est ainsi disposée obliquement dans le porteplaquette 1, comme cela ressort des figures 2 et 3 (angle 1/2 de MC et 1/2 de ss). Mais le fait que les angles CC et A soient partiellement ménagés dans le porte-plaquette I a pour résultat de simplifier la fabrication de la plaquette 6 coupante et donc d'en diminuer le coût.  Figures 4, 5 and 6 show the cutting plate 6 having a portion remote from the tongue-shaped cutting edge 8. The angles θ, λ, and g are the various clearance angles required for a cutting tool. The angles or and A are advantageously arranged for half of their absolute value in the wafer carrier 1, which is obtained by a corresponding conformation of the recess 2. Admittedly, the cutting wafer 6 is thus arranged obliquely in the carrier plate 1, as is apparent from Figures 2 and 3 (1/2 MC and 1/2 ss). But the fact that the angles CC and A are partially formed in the wafer carrier I has the result of simplifying the manufacture of the wafer 6 cutting and thus to reduce the cost.
