Description

DISPOSITIF DE DERIVATION POUR TUBE DE TRANSFERT DE FLUIDE
La présente invention a pour objet un dispositif de dérivation destiné à être posé sur un tube de transfert de fluide, en particulier pour les applications automobiles.BYPASS DEVICE FOR FLUID TRANSFER TUBE
The present invention relates to a bypass device intended to be placed on a fluid transfer tube, in particular for automotive applications.

Les techniques connues, par exemple celle qui met en oeuvre un surmoulage sur un tube en caoutchouc, présentent une certaine complication de mise en oeuvre qui augmente les coûts. The known techniques, for example that which uses overmolding on a rubber tube, present a certain complication of implementation which increases the costs.

La présente invention a pour objet un dispositif de dérivation de mise en oeuvre simplifiée. The present invention relates to a simplified implementation bypass device.

L'idée de base de l'invention est de réaliser par une seule et même opération le forage d'un trou de dérivation et la pose d'un accessoire de dérivation. The basic idea of the invention is to carry out by a single operation the drilling of a bypass hole and the installation of a bypass accessory.

L'invention concerne ainsi un dispositif de dérivation destiné à être posé sur un tube de transfert de fluide et présentant une ouverture de passage de fluide caractérisé en ce qu'il comporte, d'une part, un élément de forage permettant de réaliser par sa translation un trou de dérivation sur le tube et, d'autre part, un élément de fixation du dispositif de dérivation sur le tube, cet élément de fixation venant en contact avec le tube grâce à ladite translation, ce qui permet de réaliser le trou de dérivation sur le tube lors de la pose du dispositif de dérivation. The invention thus relates to a bypass device intended to be placed on a fluid transfer tube and having a fluid passage opening characterized in that it comprises, on the one hand, a drilling element making it possible to achieve by its translation a bypass hole on the tube and, on the other hand, a fixing element of the bypass device on the tube, this fixing element coming into contact with the tube through said translation, which makes it possible to produce the bypass on the tube when installing the bypass device.

Selon une première variante, le dispositif de dérivation présente un embout comportant ledit élément de forage et ledit élément de fixation. Cet embout peut coopérer avec un outil de pose présentant une face d'extrémité qui vient en contact avec l'élément de fixation. According to a first variant, the bypass device has a tip comprising said drilling element and said fixing element. This tip can cooperate with a fitting tool having an end face which comes into contact with the fixing element.

Selon une variante préférée, le dispositif de dérivation comporte un outil de forage et de pose comportant ledit élément de forage ainsi qu'un logement cylindrique pour une pièce formant embout dans laquelle est ménagée l'ouverture de passage, la pièce formant embout présentant à une extrémité ledit élément de fixation, et lorsque la pièce formant embout est disposée en butée dans son logement, ledit élément de forage dépasse de la première extrémité. According to a preferred variant, the bypass device comprises a drilling and laying tool comprising said drilling element as well as a cylindrical housing for a piece forming a nozzle in which the passage opening is formed, the piece forming a nozzle having a end of said fixing element, and when the end piece is placed in abutment in its housing, said drilling element protrudes from the first end.

Ces deux variantes se différencient donc par le fait que, dans la première variante, l'élément de forage est porté par l'embout, alors que dans la variante préférée, l'élément de forage est porté par l'outil de pose, l'embout permettant le passage d'une extrémité forante de l'élément de forage. Dans les deux cas, le forage du tube est réalisé simultanément à la pose du dispositif de dérivation, soit par un élément de forage constitutif de l'embout de dérivation (première variante), soit par un élément de forage constitutif de l'outil de pose (variante préférée). These two variants are therefore differentiated by the fact that, in the first variant, the drilling element is carried by the end piece, while in the preferred variant, the drilling element is carried by the setting tool, the tip allowing the passage of a drilling end of the drilling element. In both cases, the tube is drilled simultaneously with the installation of the bypass device, either by a drilling element constituting the bypass nozzle (first variant), or by a drilling element constituting the tool for pose (preferred variant).

Ladite butée est avantageusement une face d'extrémité de l'outil de forage et de pose qui vient en contact avec l'élément de fixation. Said stopper is advantageously an end face of the drilling and laying tool which comes into contact with the fixing element.

Dans le cadre de l'une ou l'autre des deux variantes ci-dessous, l'élément de forage peut être autoforant, et par exemple, il présente à cet effet des ailettes, ou bien encore, il peur être constitué par un poinçon, et dans l'un ou l'autre car il est de préférence couplé avec un dispositif vibrant, par exemple pour former une sonotrode. In the context of one or the other of the two variants below, the drilling element can be self-drilling, and for example, it has for this purpose fins, or even, it can be constituted by a punch , and in one or the other because it is preferably coupled with a vibrating device, for example to form a sonotrode.

Toujours dans le cadre de l'une ou l'autre des deux variantes précitées, l'élément de fixation est de préférence une collerette présentant un contour cylindrique tournant sa concavité vers le tube et ayant un diamètre sensiblement égal au diamètre d'un contour extérieur dudit tube. Le contour cylindrique de la collerette présente un axe qui forme un angle de préférence égal à 900 avec un axe d'insertion du dispositif de dérivation.  Still in the context of one or other of the two aforementioned variants, the fixing element is preferably a flange having a cylindrical contour turning its concavity towards the tube and having a diameter substantially equal to the diameter of an external contour of said tube. The cylindrical contour of the flange has an axis which forms an angle preferably equal to 900 with an axis of insertion of the bypass device.

L'invention concerne également un procédé de pose d'un dispositif de dérivation de type précité comptant les étapes suivantes
a) réaliser un trou de forage dans le tube à l'aide de l'élément de forage en translatant celui-ci selon une direction inclinée par rapport à un axe longitudinal du tube jusqu'à ce que l'élément de fixation vienne en contact avec le tube.The invention also relates to a method for installing a bypass device of the aforementioned type, comprising the following steps
a) drill a hole in the tube using the drilling element by translating the latter in a direction inclined relative to a longitudinal axis of the tube until the fixing element comes into contact with the tube.

b) solidariser l'élément de fixation avec le tube. b) securing the fastening element with the tube.

D'autres caractéristiques et avantages de l'invention apparaîtront mieux à la lecture de la description qui va suivre, en liaison avec les dessins ci-annexés, dans lesquels
- les figures la et lb représentent respectivement en vue latérale et en coupe AA la première variante du dispositif selon l'invention.Other characteristics and advantages of the invention will appear better on reading the description which follows, in conjunction with the attached drawings, in which
- Figures la and lb show respectively in side view and in section AA the first variant of the device according to the invention.

- la figure 2 représente en coupe longitudinale la variante préférée du dispositif selon l'invention. - Figure 2 shows in longitudinal section the preferred variant of the device according to the invention.

- et la figure 3 représente en coupe un tube équipé d'un dispositif correspondant à la figure 2. - and Figure 3 shows in section a tube fitted with a device corresponding to Figure 2.

Les figures la et lb représentent un embout autoforant destiné à former un bouchon de type purge. Figures la and lb show a self-drilling tip intended to form a purge type plug.

L'embout, par exemple en matière plastique, se présente sous la forme d'une pièce moulée monobloc comportant un tube 1 présentant une paroi interne 16 et une paroi externe 17, la paroi externe 17 comportant un filetage 3 permettant le montage d'un bouchon à l'extrémité 2 du tube 1. L'embout présente une collerette 4 présentant une face concave 8 dont le contour correspond au contour extérieur 31 du tube 30 auquel l'embout doit être solidarisé.The end piece, for example made of plastic, is in the form of a one-piece molded part comprising a tube 1 having an internal wall 16 and an external wall 17, the external wall 17 comprising a thread 3 allowing the mounting of a plug at the end 2 of the tube 1. The end piece has a collar 4 having a concave face 8 whose outline corresponds to the outside outline 31 of the tube 30 to which the end piece must be secured.

Cette solidarisation s'effectue de préférence par soudure de la face concave 8 au contour extérieur 31 du tube. Cette soudure peut être effectuée par vibrations, par ultrasons, ou bien encore par soudure thermique. La solidarisation peut être également réalisée différemment, par exemple par collage. This joining is preferably carried out by welding the concave face 8 to the outer contour 31 of the tube. This welding can be carried out by vibration, by ultrasound, or even by thermal welding. The joining can also be carried out differently, for example by gluing.

L'embout présente également des ailettes autoforantes 10, par exemple au nombre de 4 et faisant entre elles un angle, par exemple de 900, comme représenté. The end piece also has self-drilling fins 10, for example 4 in number and forming an angle between them, for example 900, as shown.

Ces ailettes auto forantes 10 sont délimitées par une surface externe curviligne 11 et à bords coupants s'étendant entre la paroi externe 17 et la pointe 12, et une surface interne, ici également curviligne, 14 s'étendant depuis le paroi interne 16 et le point 15. Le tube 1 présente un canal central 18 qui se prolonge par les régions de passage 19 situées entre les ailettes 10. These self-drilling fins 10 are delimited by a curvilinear external surface 11 and with cutting edges extending between the external wall 17 and the tip 12, and an internal surface, here also curvilinear, 14 extending from the internal wall 16 and the point 15. The tube 1 has a central channel 18 which is extended by the passage regions 19 situated between the fins 10.

La pose de l'embout s'effectue de la manière suivante. La pointe 12 de l'embout est mise en contact avec un endroit choisi du contour extérieur 31 du tube 30. On exerce sur l'embout une force parallèle à son axe
XX', cette force étant suffisante pour que les ailettes autoforantes 10 percent le tube. Cette force est exercée de préférence à l'aide de l'outil de pose 70 qui présente un corps central 75 et une région, par exemple cylindrique, 71 délimitant un logement 72 recevant le tube 1, cette région 71 se terminant par une face d'extrémité 73 ayant de préférence un profil épousant la face 7 de la collerette 4. La face d'extrémité 73 est disposée en appui sur la face 7 et l'outil de pose 70 est déplacé parallèlement à l'axe xx' dans le sens de l'enfoncement des ailettes autoforantes 10. Le déplacement de l'embout se poursuit alors jusqu'à ce que la face concave 8 épouse le contour extérieur 31 du tube.The fitting of the end piece is carried out as follows. The tip 12 of the endpiece is brought into contact with a selected location on the external contour 31 of the tube 30. A force is exerted on the endpiece parallel to its axis
XX ', this force being sufficient for the self-drilling fins 10 to pierce the tube. This force is preferably exerted using the setting tool 70 which has a central body 75 and a region, for example cylindrical, 71 delimiting a housing 72 receiving the tube 1, this region 71 ending in a face d 'end 73 preferably having a profile matching the face 7 of the flange 4. The end face 73 is disposed in abutment on the face 7 and the fitting tool 70 is moved parallel to the axis xx' in the direction of the depression of the self-drilling fins 10. The displacement of the end piece then continues until the concave face 8 follows the outer contour 31 of the tube.

La pénétration des ailettes de forage 10 peut être facilitée par un ramollissement du tube 30 qui est obtenu en mettant en vibrations l'embout de forage, voire par apport thermique. On solidarise ensuite la face concave 8 au contour 31 du tube, de manière à obtenir une dérivation. On retire ensuite l'outil de pose 70.The penetration of the drilling fins 10 can be facilitated by a softening of the tube 30 which is obtained by vibrating the drill bit, or even by thermal input. The concave face 8 is then secured to the contour 31 of the tube, so as to obtain a bypass. The fitting tool 70 is then removed.

La variante préférée représentée à la figure 2 compte un outil de forage et de pose, par exemple sous forme d'une pièce moulée monobloc, désigné par le repère général 40. I1 comporte un corps central 49 qui se prolonge par une région cylindrique centrale 41 délimitée par un contour extérieur 45 et se terminant par un poinçon 42 dont le contour curviligne 43, qui peut notamment être un contour de révolution, se termine par une pointe 44. La région cylindrique centrale 41 est entourée par une région tubulaire 46 présentant un contour intérieur 47 qui délimite, avec le contour extérieur 45 et le fond de gorge 48, un logement cylindrique 56 pour une pièce 50 formant embout. La région tubulaire 46, qui prolonge le corps central 49 et qui est coaxiale (selon l'axe XX) à la région, par exemple cylindrique, 41, se termine par une face d'extrémité 57, ayant de préférence un profil épousant la face 7 de la collerette 4. The preferred variant shown in FIG. 2 has a drilling and laying tool, for example in the form of a one-piece molded part, designated by the general reference 40. I1 comprises a central body 49 which is extended by a central cylindrical region 41 delimited by an external contour 45 and ending with a punch 42 whose curvilinear contour 43, which can in particular be a contour of revolution, ends with a point 44. The central cylindrical region 41 is surrounded by a tubular region 46 having a contour inside 47 which delimits, with the outside contour 45 and the bottom of the groove 48, a cylindrical housing 56 for a part 50 forming a nozzle. The tubular region 46, which extends the central body 49 and which is coaxial (along the axis XX) to the region, for example cylindrical, 41, ends with an end face 57, preferably having a profile matching the face 7 of the collar 4.

L'embout 50 présente une région tubulaire 51 pourvue d'un filetage d'extrémité 52, l'intérieur du tube 51 définissant le canal 18 précité. L'extrémité 53 de la pièce 50 qui est opposée au filetage 52 présente une collerette 4 de forme sensiblement identique à celle de la collerette des figures la et lb, de sorte que, comme représenté à la figure 3, sa face 8 épouse la contour externe du tube 30. Comme la collerette 4 est disposée à l'extrémité 53 de l'embout 50, sa face 8 s'étend jusqu'au bord interne 54 du tube 51. The end piece 50 has a tubular region 51 provided with an end thread 52, the inside of the tube 51 defining the aforementioned channel 18. The end 53 of the part 50 which is opposite the thread 52 has a flange 4 of shape substantially identical to that of the flange of Figures la and lb, so that, as shown in Figure 3, its face 8 follows the contour external of the tube 30. As the collar 4 is disposed at the end 53 of the end piece 50, its face 8 extends to the internal edge 54 of the tube 51.

La pose du dispositif est réalisée de la manière suivante
La région tubulaire 51 de l'embout 50 est introduite dans le logement 56, comme représenté à la figure 2. The installation of the device is carried out as follows
The tubular region 51 of the end piece 50 is introduced into the housing 56, as shown in FIG. 2.

La pointe 44 est ensuite appuyée sur le contour externe 31 du tube 30. On couple l'embout 50 par son corps central 49 à un générateur de vibrations par exemple un générateur d'ultrasons 60 formant avec la pièce 50 un sonotrode, et on enfonce l'outil 40 de préférence parallèlement à l'axe XX' en perçant le trou 35 et en poursuivant la translation jusqu'à ce que la face 8 de la collerette vienne en butée sur le contour 31 du tube 30. The tip 44 is then supported on the external contour 31 of the tube 30. The end piece 50 is coupled by its central body 49 to a vibration generator, for example an ultrasound generator 60 forming with the part 50 a sonotrode, and it is pressed the tool 40 preferably parallel to the axis XX 'by drilling the hole 35 and continuing the translation until the face 8 of the collar comes into abutment on the contour 31 of the tube 30.

Ensuite, la soudure par ultrasons est obtenue directement en fournissant par l'intermédiaire du générateur de vibrations, par exemple d'ultrasons, 60 une puissance suffisante pour que la face 57 qui s'appuie sur le contour 7 de la collerette 4 transmette une énergie assurant la soudure du contour convexe 8 sur l'extérieur 31 du tube 30. Then, the ultrasonic welding is obtained directly by supplying, via the vibration generator, for example an ultrasound generator, 60 sufficient power so that the face 57 which rests on the contour 7 of the flange 4 transmits energy. ensuring the welding of the convex contour 8 on the outside 31 of the tube 30.

On retire ensuite l'outil 40 pour obtenir une dérivation telle que représentée à la figure 3. Comme dans le cas des figures la et lb, la solidarisation de la collerette 4 au tube 30 peut être obtenue par d'autres moyens, notamment par collage, par exemple dans le cas d'un tube en élastomère. The tool 40 is then removed to obtain a derivation as shown in FIG. 3. As in the case of FIGS. 1a and 1b, the attachment of the flange 4 to the tube 30 can be obtained by other means, in particular by gluing , for example in the case of an elastomer tube.

Le dispositif selon l'invention permet ainsi de réaliser des dérivations ou des accessoires tels que des purges, prises de température ou de pression etc.  The device according to the invention thus makes it possible to produce diversions or accessories such as purges, temperature or pressure measurements, etc.

avec une grande simplicité technique.with great technical simplicity.

L'outil de pose 40 ou 70 est généralement en métal, par exemple en titane. La technique de soudure est applicable en particulier dans le cas d'un tube et d'un embout en plastique de la même famille. Le collage peut être mis en oeuvre pour coller un tube et un embout en des plastiques qui sont ou non de la même famille, ou bien dans le cas d'un tube en élastomère. On peut également utiliser à titre de colle entre un embout et un tube en plastique, un plastique intermédiaire qui fait fonction de colle en fondant.  The setting tool 40 or 70 is generally made of metal, for example titanium. The welding technique is applicable in particular in the case of a tube and a plastic tip of the same family. Gluing can be used to glue a tube and a nozzle made of plastics which may or may not be from the same family, or else in the case of an elastomer tube. It is also possible to use, as glue between a nozzle and a plastic tube, an intermediate plastic which acts as glue when melting.
