Description

Pince pour le dénudage d'élément tubulaire, en particulier de câble ou similairePliers for stripping a tubular element, in particular cable or the like
La présente invention concerne une pince pour le dénudage d'élément tubulaire, en particulier de câble, tel qu'un câble électrique ou similaire, du type formé de deux branches articulées en un point intermédiaire autour d'un axe commun, l'une des branches portant au moins un organe de coupe rotatif pour le tranchage longitudinal de l'élément tubulaire à dénuder, l'autre branche étant munie de moyens de centrage et d'appui de l'élément tubulaire, moyens de centrage et organe de coupe coopérant entre eux pour délimiter un passage de l'élément tubulaire.The present invention relates to a clamp for stripping a tubular element, in particular a cable, such as an electric cable or the like, of the type formed of two branches articulated at an intermediate point about a common axis, one of branches carrying at least one rotary cutting member for longitudinal slicing of the tubular element to be stripped, the other branch being provided with means for centering and supporting the tubular element, centering means and cutting member cooperating between they delimit a passage of the tubular element.
Un tel outil pour le dénudage de câble électrique ou similaire est décrit dans le brevet FR-A-2.044.600. Cet outil, conforme à celui représenté aux figures 1 A et 1 B, présente un certain nombre d'inconvénients. En effet, les moyens de centrage et d'appui du câble portés par une branche de la pince sont montés fixes sur cette dernière. Ils sont généralement constitués par un galet de guidage à gorge trapézoïdale ou une mâchoire en V, disposé(e) en face de l'organe de coupe. De ce fait, suivant le diamètre du câble et l'ouverture de la pince, l'axe du câble se déplace par rapport à l'un des bras de la pince. L'axe de traction sur la pince et l'axe longitudinal du câble forment alors un angle entre eux rendant difficile, voire impossible une telle traction due au changement de direction des efforts de traction sur la pince. Ainsi, dans la figure 1 , l'effort F1 pour tirer sur les branches de la pince est important mais la coupe longitudinale est possible. Dans la figure 1 B, eu égard à l'orientation du câble dans l'axe du bras de l'une des pinces, l'effort F2 à produire pour tirer sur les branches de la pince ne peut être produit manuellement. Par ailleurs, on constate que le plan normal au câble passant par l'axe de la molette de coupe se déplace vers l'arrière des moyens de centrage et d'appui et n'est plus centré par rapport aux moyens d'appui et de centrage. On aboutit alors à une position de coupe dans laquelle l'organe de coupe appuie sur le câble en un point qui n'est plus soutenu par les moyens de centrage et d'appui rendant à nouveau difficile voire impossible la coupe. Une solution pour accroître le guidage du câble lors de la coupe longitudinale du câble est décrite dans le brevet EP-A-0.366.512. Cette solution consiste à rapporter, en amont de l'organe de coupe qui coopère avec des moyens de centrage et d'appui, des organes de guidage supplémentaires formés d'un organe de coupe associé à un galet de guidage, l'organe de coupe étant monté sur un bras oscillant. Cette solution, outre sa complexité, car elle oblige à rapporter un organe de coupe et un galet, ne résout pas le problème mentionné ci-dessus du changement d'orientation de l'effort pour tirer sur la pince. On observe à nouveau un déplacement vers l'arrière ou vers l'avant du plan normal au câble passant par l'axe de la molette de coupe en fonction du diamètre et du profil du câble.Such a tool for stripping electric cable or the like is described in FR-A-2,044,600. This tool, according to that shown in Figures 1A and 1B, has a number of disadvantages. Indeed, the centering and support means of the cable carried by a branch of the clamp are fixedly mounted on the latter. They are generally constituted by a trapezoidal groove guide roller or a V-shaped jaw, disposed (e) in front of the cutting member. As a result, depending on the diameter of the cable and the opening of the clamp, the axis of the cable moves relative to one of the arms of the clamp. The traction axis on the clamp and the longitudinal axis of the cable then form an angle between them making it difficult, if not impossible, such traction due to the change of direction of the traction forces on the clamp. Thus, in Figure 1, the force F1 to pull on the branches of the clamp is important but the longitudinal section is possible. In FIG. 1B, with regard to the orientation of the cable in the axis of the arm of one of the clamps, the force F2 to be produced to pull on the branches of the clamp can not be produced manually. Furthermore, it can be seen that the plane normal to the cable passing through the axis of the cutting wheel moves towards the rear of the centering and support means and is no longer centered with respect to the support means and centering. This leads to a cutting position in which the cutting member rests on the cable at a point that is no longer supported by the centering and support means making it difficult again or impossible to cut. A solution for increasing the guiding of the cable during longitudinal cutting of the cable is described in EP-A-0,366,512. This solution consists in reporting, upstream of the cutting member which cooperates with centering and support means, additional guide members formed of a cutting member associated with a guide roller, the cutting member being mounted on an oscillating arm. This solution, in addition to its complexity, because it requires reporting a cutting member and a roller, does not solve the aforementioned problem of changing the orientation of the force to pull on the clamp. There is again a movement backwards or forwards of the plane normal to the cable passing through the axis of the cutting wheel according to the diameter and the cable profile.
Un but de la présente invention est donc de proposer une pince dont la conception permet que l'effort de traction à exercer sur les branches lors d'une coupe longitudinale de l'élément tubulaire reste de valeur et de direction constantes, quels que soient les diamètres et profils de l'élément tubulaire.An object of the present invention is therefore to provide a clamp whose design allows the tensile force to be exerted on the branches during a longitudinal section of the tubular element remains of constant value and direction, whatever the diameters and profiles of the tubular element.
A cet effet, l'invention a pour objet une pince pour le dénudage d'élément tubulaire, en particulier de câble, tel qu'un câble électrique ou similaire, du type formé de deux branches articulées en un point intermédiaire autour d'un axe commun, l'une des branches portant au moins un organe de coupe rotatif pour le tranchage longitudinal de l'élément tubulaire à dénuder, l'autre branche étant munie de moyens de centrage et d'appui de l'élément tubulaire, moyens de centrage et organe de coupe coopérant entre eux pour délimiter un passage de l'élément tubulaire, caractérisée en ce que les moyens de centrage et d'appui délimitent au moins une surface d'appui oscillant autour d'un axe pivot situé sensiblement en regard de l'axe de rotation de l'organe de coupe associé, axe de rotation de l'organe de coupe et axe pivot étant alignés le long d'une ligne sensiblement perpendiculaire à l'axe longitudinal de passage de l'élément tubulaire pour permettre à la surface d'appui de s'auto-orienter en fonction des diamètres et profils de l'élément tubulaire pour maintenir constante, de préférence dans l'axe de l'élément tubulaire, la direction des efforts de traction exercés sur les branches de la pince. Grâce à la conception des moyens d'appui et de centrage sous forme d'une surface d'appui auto-orientable, ladite surface d'appui délimite un appui qui conserve une orientation sensiblement constante et un positionnement sans décalage latéral par rapport au plan passant par les axes de rotation de l'organe de coupe et des moyens d'appui et de centrage au cours de l'ouverture et de la fermeture de la pince, quel que soit le diamètre de l'élément tubulaire. Ainsi, l'opération de coupe peut s'opérer de manière précise avec un effort F de traction exercé sur les branches de la pince demeurant sensiblement constant, quel que soit le diamètre de l'élément tubulaire.For this purpose, the subject of the invention is a clamp for stripping a tubular element, in particular a cable, such as an electric cable or the like, of the type formed of two branches hinged at an intermediate point about an axis. common, one of the branches carrying at least one rotary cutting member for the longitudinal slicing of the tubular element to be stripped, the other branch being provided with centering and bearing means of the tubular element, centering means and cutting member cooperating with each other to define a passage of the tubular element, characterized in that the centering and bearing means delimit at least one bearing surface oscillating about a pivot axis located substantially opposite the axis of rotation of the associated cutting member, axis of rotation of the cutting member and pivot axis being aligned along a line substantially perpendicular to the longitudinal axis of passage of the tubular element to allow the area support to self-orientate according to the diameters and profiles of the tubular element to maintain constant, preferably in the axis of the tubular element, the direction of the tensile forces exerted on the branches of the clamp. Thanks to the design of the support and centering means in the form of a self-orienting support surface, said bearing surface delimits a support which maintains a substantially constant orientation and a positioning without lateral offset with respect to the passing plane. by the axes of rotation of the cutting member and the support and centering means during the opening and closing of the clamp, regardless of the diameter of the tubular element. Thus, the cutting operation can be performed accurately with a tensile force F exerted on the branches of the clamp remaining substantially constant, regardless of the diameter of the tubular element.

Comme mentionné ci-dessus, la pince 1, objet de l'invention, est destinée au dénudage d'élément tubulaire généralement cylindrique. Elle sera plus particulièrement décrite ici dans le cadre d'une application au dénudage de câble 2 électrique ou similaire. Cette pince est formée de deux branches 3, 4 articulées en un point intermédiaire autour d'un axe 5 commun. L'une 3 des branches 3, 4 du câble porte au moins un organe 6 de coupe rotatif pour le tranchage longitudinal du câble 2 à dénuder. Généralement, les branches 3, 4 de la pince 1 sont en outre équipées d'au moins un organe 16 de coupe rotatif supplémentaire pour la réalisation d'une coupe circulaire ou radiale du câble 2 à dénuder. Dans les exemples représentés, la même branche, représentée en 3, porte à la fois l'organe 6 de coupe longitudinal et les organes 16 de coupe radiaux. L'organe 6 de coupe longitudinal est disposé d'un côté de la branche, tandis que les organes de coupe radiaux sont disposés de l'autre côté de ladite branche. L'organe 6 de coupe longitudinal est constitué d'une lame circulaire montée folle sur un axe 11 fixé à la branche de ladite pince. Un galet cylindrique est monté fou sur le même axe de part et d'autre de la lame. Un capot de protection est également porté par le même axe et s'étend autour d'une partie de la lame. Un tel organe de coupe est bien connu à ceux versés dans cet art.As mentioned above, the clamp 1, object of the invention, is intended for stripping tubular element generally cylindrical. She will be more particularly described here in the context of an application to the stripping of electric cable 2 or the like. This clamp is formed of two branches 3, 4 hinged at an intermediate point about a common axis 5. One of the branches 3, 4 of the cable carries at least one rotary cutting member 6 for the longitudinal slicing of the cable 2 to be stripped. Generally, the branches 3, 4 of the clamp 1 are furthermore equipped with at least one additional rotary cutting member 16 for producing a circular or radial cut of the cable 2 to be stripped. In the examples shown, the same branch, shown at 3, bears both the longitudinal cutting member 6 and the radial cutting members 16. The longitudinal cutting member 6 is arranged on one side of the branch, while the radial cutting members are arranged on the other side of said branch. The longitudinal cutting member 6 consists of a circular blade mounted idle on an axis 11 fixed to the branch of said clamp. A cylindrical roller is mounted crazy on the same axis on both sides of the blade. A protective cover is also carried by the same axis and extends around a portion of the blade. Such a cutting member is well known to those skilled in the art.
Les organes 16 de coupe radiaux sont de conception analogue. A chaque fois, l'axe de rotation des organes de coupe radiaux ou longitudinaux s'étend sensiblement parallèlement à l'axe 5 commun d'articulation des branches 3, 4 de la pince.The radial cutting members 16 are of similar design. Each time, the axis of rotation of the radial or longitudinal cutting members extends substantially parallel to the common axis 5 articulation of the branches 3, 4 of the clamp.
L'autre branche, représentée en 4, de la pince 1 , est munie de moyens 7 de centrage et d'appui du câble 2. Les moyens 7 de centrage et d'appui et l'organe 6 de coupe coopèrent entre eux pour délimiter un passage 8 de câble 2. Ces moyens 7 de centrage et d'appui pour le câble 2 sont disposés en regard de l'organe 6 de coupe longitudinal. Ces moyens 7 de centrage et d'appui délimitent au moins une surface 9 d'appui oscillant autour d'un axe 10 pivot et montée fixe axialement par rapport audit axe 10 pivot. La surface 9 d'appui est donc montée oscillant de manière permanente par un montage à pivotement libre autour de l'axe 10 pivot. Ce montage à pivotement libre de la surface 9 d'appui, fixe axialement, à l'intérieur d'une plage angulaire prédéterminée permet une auto-orientation permanente de ladite surface 9 d'appui. Cet axe 10 pivot est situé sensiblement en regard de l'axe 11 de rotation de l'organe 6 de coupe associé. Axe 11 de rotation de l'organe 6 de coupe et axe 10 pivot sont alignés le long d'une ligne sensiblement perpendiculaire à l'axe longitudinal de passage 8 du câble 2 pour permettre à la surface 9 d'appui de s'auto-orienter en fonction des diamètres et profils de câble 2 pour maintenir constante, de préférence dans l'axe du câble 2, la direction des efforts F de traction exercés sur les branches 3, 4 de la pince 1. Ainsi, l'effort F de traction et l'axe longitudinal du câble sont sensiblement alignés, ce qui permet d'exercer un effort relativement faible sur les branches 3, 4 de la pince. Au cours de son auto-orientation, la surface 9 d'appui peut être amenée à pivoter suivant deux directions autour de l'axe pivot 10. La surface 9 d'appui ne peut en aucun cas se déplacer axialement par rapport à son axe de pivotement au cours de son auto-orientation. On note dans les figures que l'axe 10 pivot, l'axe 11 de rotation de l'organe 6 de coupe et l'axe 5 d'articulation des branches sont trois axes sensiblement parallèles qui forment un triangle.The other branch, represented at 4, of the clamp 1, is provided with means 7 for centering and supporting the cable 2. The centering and support means 7 and the cutting member 6 cooperate with one another to define a passage 8 of cable 2. These means 7 of centering and support for the cable 2 are arranged facing the longitudinal cutting member 6. These means 7 of centering and support delimit at least one bearing surface 9 oscillating about a pivot axis 10 and fixedly mounted axially with respect to said pivot axis. The bearing surface 9 is therefore mounted permanently oscillating by a freely pivotable mounting about the pivot axis. This pivotally free mounting of the bearing surface 9, fixed axially, within a predetermined angular range allows permanent self-orientation of said bearing surface 9. This pivot axis 10 is located substantially opposite the axis 11 of rotation of the associated cutting member 6. Axis 11 of rotation of the cutting member 6 and axis 10 pivot are aligned along a line substantially perpendicular to the longitudinal axis of passage 8 of the cable 2 to allow the bearing surface 9 to self-support. orienting according to the diameters and cable profiles 2 to maintain constant, preferably in the axis of the cable 2, the direction of the tensile forces F exerted on the branches 3, 4 of the clamp 1. Thus, the force F of traction and the longitudinal axis of the cable are substantially aligned, which allows to exert a relatively low force on the branches 3, 4 of the clamp. During its self-orientation, the bearing surface 9 can be pivoted in two directions about the pivot axis 10. The bearing surface 9 can in no case move axially relative to its axis of rotation. pivoting during its self-orientation. It is noted in the figures that the pivot axis 10, the axis 11 of rotation of the cutting member 6 and the hinge axis 5 of the branches are three substantially parallel axes which form a triangle.
Les moyens 7 d'appui et de centrage peuvent affecter un grand nombre de formes. Dans un premier mode de réalisation, représenté à la figure 4, les moyens 7 d'appui et de centrage sont constitués par un train de galets 12 formant la surface 9 d'appui. Ces galets 12 sont montés à rotation sur une platine 13 commune reliée, à l'une des branches 4 de la pince 1 , de manière oscillante autour dudit axe 10 pivot.The support and centering means 7 can affect a large number of shapes. In a first embodiment, shown in FIG. 4, the support and centering means 7 consist of a roller train 12 forming the bearing surface 9. These rollers 12 are mounted to rotate on a common plate 13 connected to one of the branches 4 of the clamp 1, oscillating about said pivot axis 10.
Dans un autre mode de réalisation représenté aux figures 3 et 5, les moyens 7 d'appui et de centrage sont constitués par une mâchoire 14 de guidage à profil transversal en V1 ladite mâchoire 14 étant reliée à l'une 4 des branches 3, 4 de la pince 1 de manière oscillante autour dudit axe 10 pivot. Les faces internes du V constituant la surface 9 d'appui peuvent être formées par des rouleaux 15 à pivotement libre qui facilitent le déplacement relatif entre pince et câble.In another embodiment shown in FIGS. 3 and 5, the support and centering means 7 are constituted by a transverse profile guide jaw 14 in V 1, said jaw 14 being connected to one of the four branches 3, 4 of the clip 1 oscillating about said pivot axis. The internal faces of the V constituting the bearing surface 9 can be formed by free-swinging rollers 15 which facilitate the relative movement between clamp and cable.
De préférence, la surface 9 d'appui, délimitée par les moyens 7 de centrage et d'appui, est montée oscillante à l'intérieur d'une plage angulaire prédéterminée délimitée par deux butées de fin de course non représentées. Ces butées de fin de course peuvent être formées par les bords dits transversaux d'une lumière oblongue ménagée dans les moyens 7 de centrage et d'appui, cette lumière coopérant avec un axe porté par la branche 4 de la pince munie desdits moyens 7 de centrage. Ainsi, le déplacement à pivotement des moyens 7 de centrage et d'appui est possible entre deux positions extrêmes correspondant chacune au contact de l'axe avec un bord dit transversal de la lumière. Bien évidemment, un montage inverse, à savoir l'axe étant porté par les moyens 7 d'appui, la lumière par la branche 4 de la pince aurait également pu être envisagé de manière équivalente.Preferably, the bearing surface 9 delimited by the centering and bearing means 7 is mounted oscillating within a predetermined angular range. delimited by two end stops not shown. These limit stops can be formed by the so-called transverse edges of an oblong slot formed in the means 7 of centering and support, this light cooperating with an axis carried by the branch 4 of the clamp provided with said means 7 of centering. Thus, the pivoting movement of the centering and support means 7 is possible between two extreme positions each corresponding to the contact of the axis with a transverse edge of the light. Of course, a reverse assembly, namely the axis being carried by the support means 7, the light by the branch 4 of the clamp could also be considered in an equivalent manner.
Le fonctionnement d'une pince conforme à l'invention est analogue à celui décrit dans l'état de la technique. En effet, il suffit de positionner le câble 2 à l'intérieur du passage 8 de câble s'étendant entre organe 6 de coupe et moyens 7 d'appui, notamment à l'intérieur de la gorge en V délimitée par les moyens 7 d'appui et de centrage. Dans un second temps, il est exercé généralement manuellement un effort de traction sur les branches de la pince pour procéder à la découpe longitudinale dudit câble. La découpe radiale dudit câble peut être opérée avant ou après la découpe longitudinale. Au cours de la découpe longitudinale, les moyens 7 d'appui et de centrage délimitent une surface 9 d'appui qui s'auto-oriente par pivotement libre suivant deux directions autour de son axe 10 pivot de manière telle que l'axe de traction sur la branche de la pince et l'axe longitudinal du câble demeurent sensiblement alignés amenant l'opérateur à exercer sur le câble un effort de traction constant quel que soit le diamètre du câble à dénuder. Les butées de fin de course n'empêchent en rien le déplacement à oscillation libre des moyens d'appui et de centrage mais limite ce débattement pour empêcher une rotation complète des moyens d'appui et de centrage. The operation of a clamp according to the invention is similar to that described in the state of the art. Indeed, it suffices to position the cable 2 inside the cable passage 8 extending between the cutting member 6 and the support means 7, in particular inside the V-shaped groove delimited by the means 7 d 'support and centering. In a second step, it is generally exercised manually a tensile force on the branches of the clamp to proceed to the longitudinal cutting of said cable. The radial cut of said cable can be operated before or after the longitudinal cut. During the longitudinal cutting, the support and centering means 7 delimit a support surface 9 which is self-orienting by free pivoting in two directions about its pivot axis in such a way that the traction axis on the branch of the clamp and the longitudinal axis of the cable remain substantially aligned causing the operator to exert on the cable a constant tensile force regardless of the cable diameter to be stripped. The limit stops do not prevent the freely oscillating displacement of the support and centering means but limits this deflection to prevent complete rotation of the support and centering means.
