Outil de coupe hélicoïdale d'une enveloppe cylindrique L'invention concerne un outil de coupe hélicoïdale d'une enveloppe cylindrique en matière plastique, en particulier en matériau polymère monocouche non adhérent, gaînant un support, ledit outil comprenant un corps agencé pour pouvoir être entraîné en pivotement autour de l'axe de ladite enveloppe et portant une lame de coupe ayant une arête tranchante inclinée par rapport au plan transversal de l'enveloppe cylindrique. The invention relates to a helical cutting tool for a cylindrical envelope of plastic material, in particular in non-adherent monolayer polymer material, sheathing a support, said tool comprising a body arranged to be able to be driven. pivoting about the axis of said envelope and carrying a cutting blade having a cutting edge inclined relative to the transverse plane of the cylindrical envelope.

Ces outils sont utilisés pour dévêtir des tubes, dégarnir des câbles électriques, etc. These tools are used to strip tubes, strip electrical cables, etc.

Dans ces outils connus, la lame de coupe est montée fixe en position de travail, ce qui nécessite un positionnement très précis et difficile de l'arête tranchante en saillie de l'outil. En outre, cette saillie n'est réglable que par déplacement de la lame de coupe, ce qui rend délicat un réglage précis. In these known tools, the cutting blade is mounted fixed in the working position, which requires very precise and difficult positioning of the cutting edge projecting from the tool. In addition, this projection is adjustable only by movement of the cutting blade, which makes precise adjustment difficult.

<Desc/Clms Page number 2><Desc / Clms Page number 2>

La présente invention vise en conséquence à pallier ces inconvénients des outils connus.  The present invention therefore aims to overcome these drawbacks of known tools.

A cet effet, l'outil selon l'invention est caractérisé en ce que ladite lame de coupe est montée à une extrémité d'une tige montée coulissante dans ledit corps contre l'action d'un ressort de rappel, en saillie d'une butée d'appui solidaire de ladite tige. To this end, the tool according to the invention is characterized in that said cutting blade is mounted at one end of a rod slidably mounted in said body against the action of a return spring, projecting from a support stop integral with said rod.

Avec l'outil selon l'invention, le positionnement de l'arête de coupe se fait par rapport à la butée d'appui, ce qui permet un positionnement précis bien plus aisé que par rapport au corps de l'outil. La tige coulissante rappelée par ressort, qui porte la butée d'appui et la lame de coupe, garantit un enfoncement exactement calibré de l'arête de coupe dans l'enveloppe à couper, la surface extérieure de cette enveloppe coopérant avec la butée d'appui pour repousser la tige contre l'action de son ressort de rappel. With the tool according to the invention, the positioning of the cutting edge is done relative to the abutment stop, which allows precise positioning much easier than relative to the body of the tool. The spring-loaded sliding rod, which carries the support stop and the cutting blade, guarantees an exactly calibrated insertion of the cutting edge into the envelope to be cut, the external surface of this envelope cooperating with the stop of support to push the rod against the action of its return spring.

Selon une forme de réalisation de l'invention permettant un réglage de la profondeur de pénétration de l'arête de coupe, la butée d'appui est une pièce distincte de la tige et est réglable en coulissement selon l'axe de ladite tige pour faire varier la saillie de l'arête de coupe par rapport à la butée d'appui. According to one embodiment of the invention allowing adjustment of the penetration depth of the cutting edge, the support stop is a separate part of the rod and is adjustable in sliding along the axis of said rod to make vary the projection of the cutting edge with respect to the support stop.

L'invention sera bien comprise à la lecture de la description suivante d'un exemple de réalisation, en référence au dessin annexé dans lequel : la figure 1 est une vue schématique en perspective d'une partie d'un outil comportant la lame de coupe, la figure 2 est une vue schématique en perspective, sous un autre angle, de l'ensemble de la figure 1 et la figure 3 est une vue schématique en perspective d'une tige porte-lame de l'outil des figures 1 et 2. The invention will be clearly understood on reading the following description of an exemplary embodiment, with reference to the appended drawing in which: FIG. 1 is a schematic perspective view of a part of a tool comprising the cutting blade , Figure 2 is a schematic perspective view, from another angle, of the assembly of Figure 1 and Figure 3 is a schematic perspective view of a blade holder rod of the tool of Figures 1 and 2 .

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

En référence aux figures 1 et 2, on a représenté un corps 1 faisant partie d'un outil selon l'invention et portant une lame de coupe 2 présentant une arête tranchante 3. With reference to FIGS. 1 and 2, there is shown a body 1 forming part of a tool according to the invention and carrying a cutting blade 2 having a cutting edge 3.

En référence à la figure 3, la lame de coupe 2 est montée à une extrémité d'une tige 4 montée coulissante dans une bague 5 fixée dans un alésage traversant 6 du corps 1. La lame de coupe 2 est montée sur une tête 7 épaulée de la tige 4 par l'intermédiaire d'une vis 8 permettant l'interchangeabilité de la lame de coupe 2. Referring to Figure 3, the cutting blade 2 is mounted at one end of a rod 4 slidably mounted in a ring 5 fixed in a through bore 6 of the body 1. The cutting blade 2 is mounted on a shoulder 7 of the rod 4 by means of a screw 8 allowing the interchangeability of the cutting blade 2.

Un ressort hélicoïdal 9 est interposé entre l'épaulement de la tête 7 et la bague 5 de manière à écarter la tête 7 de la bague 5. A helical spring 9 is interposed between the shoulder of the head 7 and the ring 5 so as to separate the head 7 from the ring 5.

Dans l'exemple représenté, une butée d'appui 10, distincte de la tige 4, est montée sur la tête 7 à coulissement axial par rapport à la tige 4, sur deux broches 11, au moyen d'une vis 12 qui est avantageusement une vis de calibrage fin. In the example shown, a support stop 10, separate from the rod 4, is mounted on the head 7 with axial sliding relative to the rod 4, on two pins 11, by means of a screw 12 which is advantageously a fine calibration screw.

La bague 5 porte un téton radial 13 coopérant avec une rainure radiale 14 de l'alésage 6. La bague 5 comporte en outre une gorge périphérique 15 avec laquelle coopère un plongeur 16 en forme profilée de diabolo coulissant dans le corps 1 orthogonalement à l'axe de l'alésage 6 et rappelé vers l'extérieur du corps 1 par un ressort (non représenté). La tige 4 porte de son côté un téton radial 17 coopérant avec une rainure axiale borgne 18 de la bague 5 de manière à guider la tige 4 lors de son coulissement. The ring 5 carries a radial stud 13 cooperating with a radial groove 14 of the bore 6. The ring 5 also has a peripheral groove 15 with which a plunger 16 in the form of a diabolo profile sliding in the body 1 orthogonally to the axis of the bore 6 and returned to the outside of the body 1 by a spring (not shown). The rod 4 carries in turn a radial stud 17 cooperating with a blind axial groove 18 of the ring 5 so as to guide the rod 4 during its sliding.

La vis 12 permet donc de régler la distance axiale entre la face d'extrémité de la pièce d'appui 10 et l'arête tranchante 3 de la lame de coupe 2, qui est la profondeur de pénétration de la lame. Ce réglage se fait après démontage de l'ensemble porte-lame représenté à la figure 3. Pour ce démontage, le plongeur 16 est enfoncé contre l'action de son ressort, sa forme de diabolo libérant alors la gorge 15 de la bague 5. Une traction vers l'extérieur de la tige 4 permet alors d'effacer la lame de coupe 2 puis d'extraire l'ensemble porte-couteau guidé par la coopération du téton 13 avec la rainure 14. The screw 12 therefore makes it possible to adjust the axial distance between the end face of the support piece 10 and the cutting edge 3 of the cutting blade 2, which is the penetration depth of the blade. This adjustment is made after disassembly of the blade holder assembly shown in FIG. 3. For this disassembly, the plunger 16 is pressed against the action of its spring, its diabolo shape then releasing the groove 15 from the ring 5. An outward pull of the rod 4 then makes it possible to erase the cutting blade 2 and then to extract the knife holder assembly guided by the cooperation of the stud 13 with the groove 14.

<Desc/Clms Page number 4> <Desc / Clms Page number 4>

Le remontage se fait par une succession inverse d'opérations. The reassembly is done by a reverse sequence of operations.

Bien entendu, dans le cas d'une butée d'appui 10 non réglable, celle-ci peut être constituée de la tête 7 de la tige 4.Of course, in the case of a non-adjustable support stop 10, this can consist of the head 7 of the rod 4.
