Abstract

The procedure for joining two components (1, 2), e.g. for attaching a component to a vehicle trim strip, uses a plastic or other soft self-hardening material (3) inserted into adjoining cavities in the two components, one of which is undercut to ensure a reliable fixing. The plastic or soft material is poured or molded in the cavities and allowed to set to form a reliable fixing. The undercut cavity can be made in a variety of shapes, including dovetail or hooked section, and it can be used to hold one end of a fastener that receives the second component. The plastic material, preferably a plastomer or elastomer, can be applied manually or with a pneumatic tool and can, where necessary, be heated to harden it.

Procédé pour lier deux pièces l'une à l'autre, par complémentarité de formes, et dispositif pour la mise en oeuvre dudit procédé
La présente invention concerne un procédé de réalisation d'une liaison par obstacle entre deux pièces, à l'aide d'un moyen de liaison comprenant un matériau plastique ou plastifiable durcissable. L'invention concerne également un dispositif pour la mise en oeuvre dudit procédé selon l'invention. Method for joining two parts to each other, by complementarity of forms, and device for implementing said method
The present invention relates to a method of producing an obstacle connection between two parts, using a connection means comprising a curable plastic or plasticizable material. The invention also relates to a device for implementing said method according to the invention.

Lorsqu'on relie entre elles deux pièces, par exemple lors de la fixation d'une attache à une baguette décorative d'un véhicule automobile, on doit bien souvent veiller à ce qu'une surface décorative de la baguette, visible une fois le montage terminé, ne soit pas endommagée, ou à ce que son aspect visuel ne soit pas altéré de quelconque manière. Par exemple, aucun trou débouchant en vue d'une liaison vissée ne doit être aménagé dans la pièce. De la même manière, un chauffage trop fort lors de la réalisation de la liaison peut avoir des conséquences très négatives sur l'aspect visuel de la surface décorative et finalement rendre la pièce inutilisable.  When two parts are connected together, for example when attaching a fastener to a decorative strip of a motor vehicle, it is very often necessary to ensure that a decorative surface of the strip, visible after mounting finished, is not damaged, or that its visual appearance is not altered in any way. For example, no hole opening for a screw connection should be made in the room. In the same way, too much heating when the connection is made can have very negative consequences on the visual appearance of the decorative surface and ultimately render the part unusable.

Il est connu de relier des pièces d'une manière telle qu'une surface décorative d'une pièce ne soit pas dégradée. Habituellement, on recourt à une liaison collée entre les deux pièces
Dans un assemblage collé, les surfaces des pièces à coller doivent être préalablement préparées mécaniquement, ce qui peut être réalisé par sablage ou par action de différentes substances chimiques adaptées. La préparation mécanique, d'une part, sert à nettoyer les surfaces en vue du collage, c'est-àdire à éliminer les saletés, la graisse et autres impuretés ; d'autre part, le sablage rend les surfaces de collage rugueuses, ce qui a pour effet d'augmenter leur surface. It is known to connect parts in such a way that a decorative surface of a part is not degraded. Usually, a bonded bond is used between the two parts
In a bonded assembly, the surfaces of the parts to be bonded must be mechanically prepared beforehand, which can be achieved by sandblasting or by the action of various suitable chemical substances. Mechanical preparation, on the one hand, is used to clean surfaces for bonding, that is, to remove dirt, grease and other impurities; on the other hand, sanding makes the bonding surfaces rough, which has the effect of increasing their surface.

Bien souvent, les matériaux des pièces ne permettent pas, une application directe de l'adhésif sur les surfaces préparées mécaniquement, car l'ancrage de l'adhésif est insuffisant. Le problème est résolu en appliquant un produit d'accrochage sur les surfaces des pièces. Sur le produit d'accrochage est appliquée ensuite une couche de vernis durcisseur supplémentaire.  Very often, the materials of the parts do not allow a direct application of the adhesive to mechanically prepared surfaces, because the anchoring of the adhesive is insufficient. The problem is solved by applying a bonding product on the surfaces of the parts. An additional hardening varnish is then applied to the bonding product.

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

En général, ce n'est qu'après ces opérations de préparation que l'adhésif peut être appliqué sur les surfaces de collage et que les pièces peuvent être assemblées. Une fois les pièces assemblées et serrées, on laisse durcir l'adhésif.  In general, it is only after these preparation operations that the adhesive can be applied to the bonding surfaces and that the parts can be assembled. Once the parts are assembled and tightened, the adhesive is left to harden.

Une liaison collée présente sans aucun doute de nombreux avantages., Elle permet notamment de relier elles des pièces en pratiquement n'importe quel matériau. Avant tout, une liaison collée permet de relier entre elles des pièces non soudables ou encore des pièces très fines. Elle est fréquemment utilisée pour assembler des métaux avec des matériaux autres, tels que du bois, des matières plastiques, du caoutchouc, du verre ou de la porcelaine.  A bonded bond undoubtedly has many advantages., It makes it possible in particular to connect them pieces in practically any material. Above all, a bonded connection makes it possible to connect non-weldable parts together or even very fine parts. It is frequently used to join metals with other materials, such as wood, plastics, rubber, glass or porcelain.

Néanmoins, une liaison collée comporte un certain nombre d'inconvénients. Un inconvénient important réside dans le fait qu'une liaison collée, souvent, ne résiste pas à des charges élevées, même avec des surfaces rugueuses. Ceci est d'autant plus vrai dans le cas d'efforts de traction qui ne s'exercent pas parallèlement aux surfaces de collage : dans ce cas aucune liaison par obstacle (microscopique) ne vient renforcer la liaison collée et seules les forces d'adhésion de la liaison collée agissent.  However, a bonded bond has a number of drawbacks. An important drawback is that a bonded bond often does not withstand high loads, even with rough surfaces. This is all the more true in the case of tensile forces which are not exerted parallel to the bonding surfaces: in this case no bonding by obstacle (microscopic) reinforces the bonded bond and only the adhesion forces of the bonded bond act.

D'un autre côté, une liaison collée n'offre pas une tenue suffisante aux intempéries et souvent sa stabilité dépend dans une large mesure des influences extérieures.  On the other hand, a bonded bond does not offer sufficient resistance to bad weather and often its stability depends to a large extent on external influences.

En outre, comme on l'a vu plus haut, un nombre relativement élevé d'opérations sont nécessaires pour réaliser une liaison collée, ce qui implique un engagement en matériel important et entraîne des coûts en énergie et en matériaux élevés. A remarquer également que les émissions polluantes importantes qui accompagnent le collage ne spnt pas sans poser certains problèmes sur le plan de l'écologie.  In addition, as seen above, a relatively large number of operations are necessary to make a bonded bond, which involves a commitment in important material and involves costs in energy and in high materials. It should also be noted that the significant polluting emissions which accompany bonding are not without posing certain ecological problems.

Des pièces peuvent aussi être reliées autrement que par collage, par exemple par soudage. Un inconvénient important de la liaison par soudage est qu'elle n'est appliquable qu'avec des matériaux soudables et que, même des matériaux soudables, par exemple certains alliages d'aluminium, sont parfois difficilement soudables. Par ailleurs, le soudage conduit à une sollicitation thermique élevée du matériau, qui peut altérer l'aspect visuel d'une surface décorative d'une pièce au point que la pièce ne réponde plus aux exigences et ne soit plus utilisable.  Parts can also be connected other than by gluing, for example by welding. An important drawback of the welding connection is that it can only be applied with weldable materials and that even weldable materials, for example certain aluminum alloys, are sometimes difficult to weld. Furthermore, welding leads to a high thermal stress on the material, which can alter the visual appearance of a decorative surface of a part to the point that the part no longer meets the requirements and is no longer usable.

Partant de là, le but de la présente invention est de proposer un procédé pour relier entre elles deux pièces, parmi lesquelles l'une au moins présente une face décorative dont l'aspect visuel ne doit pas être altéré par la liaison, qui permette d'éviter les inconvénients des procédés connus de l'état de la technique.  From there, the object of the present invention is to provide a method for connecting two pieces together, among which at least one has a decorative face whose visual appearance must not be altered by the connection, which allows d 'Avoid the disadvantages of the methods known from the prior art.

La demande publiée du brevet allemand DE 199 29 480 Al décrit un procédé de collage, dans lequel des évidements, des trous ou des contredépouilles sont aménagés dans des objets plans à assembler, lesquels évidements, trous ou contre-dépouilles sont ensuite remplis d'adhésif au moment du collage.  The published application of German patent DE 199 29 480 A1 describes a bonding process, in which recesses, holes or undercuts are arranged in planar objects to be assembled, which recesses, holes or undercuts are then filled with adhesive. when pasting.

Le brevet US n 2, 255,184 présente un procédé d'assemblage de pièces, dans lequel les pièces, à des fins de liaison, sont pourvues chacune d'une cavité en contre-dépouille ouverte d'un côté.  US Patent No. 2, 255.184 presents a method of assembling parts, in which the parts, for bonding purposes, are each provided with an undercut cavity open on one side.

Le brevet US n 3, 309123 présente un procédé d'assemblage de pièces, dans lequel le moyen de liaison pour l'assemblage des pièces comporte des crochets.  US Patent No. 3, 309123 presents a method of assembling parts, in which the connecting means for assembling the parts comprises hooks.

Le modèle d'utilité allemand DE 1 956 803 U présente un procédé d'assemblage de pièces, dans lequel les pièces présentent des cavités inclinées par rapport à la surface des pièces.  The German utility model DE 1 956 803 U presents a method of assembling parts, in which the parts have cavities inclined relative to the surface of the parts.

La demande publiée du brevet allemand DE 1 752343 présente un procédé d'assemblage de pièces, dans lequel, dans une liaison collée, on ajoute un moyen de liaison supplémentaire, sous la forme d'une tige creuse.  The published application of the German patent DE 1 752343 presents a method of assembling parts, in which, in a bonded connection, an additional connection means is added, in the form of a hollow rod.

Cependant aucun des documents mentionnés ne propose un procédé tel que celui de l'invention.  However, none of the documents mentioned proposes a process such as that of the invention.

L'invention propose un procédé pour relier entre elles une première pièce et une deuxième pièce à l'aide d'un matériau plastique ou plastifiable durcissable, dans lequel la première pièce est pourvue d'au moins deux cavités inclinées par rapport à la surface de la pièce, en particulier obtenues par rotation de 1800 autour d'un axe normal à la surface de la pièce, qui communiquent entre elles et débouchent dans la même face de la pièce, dans lequel la deuxième pièce est pourvue d'au moins deux trous débouchants, qui sont alignés avec les cavités dans la première pièce, et dans lequel la première pièce est reliée à la deuxième pièce en coulant ou en moulant le matériau plastique ou plastifiable dans les trous débouchants et dans les cavités.  The invention provides a method for connecting a first part and a second part together using a curable plastic or plasticizable material, in which the first part is provided with at least two cavities inclined with respect to the surface of the part, in particular obtained by rotation of 1800 around an axis normal to the surface of the part, which communicate with each other and open into the same face of the part, in which the second part is provided with at least two holes through holes, which are aligned with the cavities in the first part, and in which the first part is connected to the second part by casting or molding the plastic or plasticizable material in the through holes and in the cavities.

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

Pour relier les deux pièces, on coule ou on moule le matériau plastique ou plastifiable dans les cavités des première et deuxième pièces. Des ouvertures supplémentaires qui débouchent dans les cavités peuvent être prévues à cet effet. Du fait de l'inclinaison des cavités, le matériau durcissable présent dans celles-ci est fermement ancré dans la pièce concernée. Le matériau durcissable, à l'extrémité des trous traversants éloignée de la face d'assemblage de la pièce, forme un collet qui retient la deuxième pièce.  To connect the two parts, the plastic or plasticizable material is poured or molded into the cavities of the first and second parts. Additional openings which open into the cavities can be provided for this purpose. Due to the inclination of the cavities, the curable material present in them is firmly anchored in the part concerned. The curable material, at the end of the through holes remote from the assembly face of the part, forms a collar which retains the second part.

Une configuration de ce type permet un remplissage très simple à l'aide du matériau durcissable, remplissage qui s'effectue soit via le trou débouchant dans la deuxième pièce, soit via la cavité inclinée qui débouche dans la surface de la première pièce.  A configuration of this type allows a very simple filling using the curable material, filling which is carried out either via the through hole in the second part, or via the inclined cavity which opens into the surface of the first part.

L'invention propose encore un procédé pour relier entre elles une première pièce et une deuxième pièce à l'aide d'un matériau plastique ou plastifiable durcissable, dans lequel la première pièce est pourvue d'au moins une cavité en contre-dépouille, ouverte d'un côté, dans laquelle le matériau plastique ou plastifiable est coulé ou moulé, dans lequel lem atériau plastifiable comporte des crochets pour la liaison avec la deuxième pièce, les crochets du matériau plastique ou plastifiable étant reliés à la deuxième pièce.  The invention also provides a method for connecting a first part and a second part to each other using a curable plastic or plasticizable material, in which the first part is provided with at least one open undercut cavity. on one side, in which the plastic or plasticizable material is cast or molded, in which the plasticizable material has hooks for connection to the second part, the hooks of the plastic or plasticizable material being connected to the second part.

De manière avantageuse, le trou non débouchant présente une section transversale circulaire ou rectangulaire. Le trou non débouchant circulaire, de préférence, a un diamètre en section transversale compris dans une plage allant de 0, 1 à 5 mm, de préférence dans une plage allant de 0, 1 à 2 mm.  Advantageously, the non-through hole has a circular or rectangular cross section. The circular through hole, preferably, has a cross-sectional diameter in the range of 0.1 to 5 mm, preferably in the range of 0.1 to 2 mm.

Conformément à un mode de réalisation avantageux de l'invention, la cavité en contre-dépouille ouverte d'un côté est une rainure.  According to an advantageous embodiment of the invention, the undercut cavity open on one side is a groove.

Conformément à la présente invention, le matériau plastique ou plastifiable peut être coulé ou injecté dans les cavités ou les trous débouchants concernés par application d'une surpression ou d'une dépression.  According to the present invention, the plastic or plasticizable material can be poured or injected into the cavities or through holes concerned by application of an overpressure or a vacuum.

En ce qui concerne le matériau durcissable, il s'agit de préférence d'un matériau thermoplastique (plastomère), d'un matériau thermodurcissable (duromère) ou d'un élastomère.  As regards the curable material, it is preferably a thermoplastic material (plastomer), a thermosetting material (duromer) or an elastomer.

Comme matériaux thermoplastiques, on peut utiliser notamment toutes les matières plastiques, par exemple des polyoléfines, des polymères vinyliques, des polyamides, des polyesters, des polyacétates, des polycarbonates, des polyuréthanes et des ionomères.  As thermoplastic materials, it is possible in particular to use all plastics, for example polyolefins, vinyl polymers, polyamides, polyesters, polyacetates, polycarbonates, polyurethanes and ionomers.

<Desc/Clms Page number 5> <Desc / Clms Page number 5>

Comme matériaux thermodurcissables, conviennent notamment toutes les matières plastiques fabriquées à partir de résines durcissables, par exemple les résines diallyphtalates, les résines époxydes, les résines uréeformaldéhydes, les résines mélamine-formaldéhydes, les résines phénolformaldéhydes et les résines polyester insaturées.  Suitable thermosetting materials are, in particular, all plastics made from curable resins, for example diallyphthalate resins, epoxy resins, urea formaldehyde resins, melamine formaldehyde resins, phenolformaldehyde resins and unsaturated polyester resins.

Comme matériaux élastomères, tous les polymères obtenus par vulcanisation de caoutchoucs naturels ou synthétiques peuvent être utilisés.  As elastomeric materials, all the polymers obtained by vulcanization of natural or synthetic rubbers can be used.

Le matériau durcissable peut être à plusieurs composants, par exemple ce peut être un matériau à deux composants. Pour augmenter la résistance de la liaison, on peut encore utiliser. des matériaux renforcés par fibres.  The curable material can be a multi-component, for example it can be a two-component material. To increase the resistance of the bond, one can still use. fiber-reinforced materials.

Le matériau plastique ou plastifiable peut de la même manière être un adhésif Outre la liaison par obstacle selon l'invention, les forces adhésives de la liaison collée permettent d'obtenir une liaison par adhérence et ainsi d'augmenter encore la résistance de l'assemblage. A la différence d'une liaison collée traditionnelle, dans laquelle on a essentiellement une liaison par adhérence, il est possible d'obtenir avec le procédé selon l'invention une liaison combinée par adhérence et par complémentarité de formes. La résistance de la liaison entre les pièces peut être augmentée, lorsque les surfaces d'assemblage des deux pièces sont pourvues au moins partiellement d'adhésif.  The plastic or plasticizable material can likewise be an adhesive. In addition to the obstacle bond according to the invention, the adhesive forces of the bonded bond make it possible to obtain a bond by adhesion and thus further increase the strength of the assembly. . Unlike a traditional bonded bond, in which there is essentially an adhesion bond, it is possible to obtain with the method according to the invention a combined bond by adhesion and by complementarity of forms. The resistance of the connection between the parts can be increased, when the joining surfaces of the two parts are provided at least partially with adhesive.

Comme solution alternative, le matériau durcissable peut être métallique. Le métal, pour sa coulée ou son moulage dans les cavités ou les trous débouchants selon l'invention, ouvertes d'un côté, dans la première et le cas échéant dans la deuxième pièce, doit seulement être chauffé à une température supérieure à la température de solidus.  As an alternative solution, the curable material can be metallic. The metal, for its casting or its molding in the cavities or through holes according to the invention, open on one side, in the first and if necessary in the second part, must only be heated to a temperature higher than the temperature of solidus.

Dans la présente invention, la première pièce et éventuellement la deuxième pièce peut comporter une surface décorative qui ne subit aucune altération optiquement pénalisante due à la liaison entre la première et la deuxième pièce. La deuxième pièce, cependant, est de préférence un élément de fixation, en particulier sous la forme d'une agrafe, d'un clips ou similaire, pour la fixation indirecte de la première pièce à un dispositif ou à un élément de montage. De manière particulièrement avantageuse, la liaison entre la première et la deuxième pièce peut être démontée par plastification du matériau durci. En particulier, un élément de fixation (c'est-à-dire la deuxième  In the present invention, the first part and possibly the second part may include a decorative surface which does not undergo any optically penalizing alteration due to the connection between the first and the second part. The second part, however, is preferably a fastening element, in particular in the form of a clip, a clip or the like, for the indirect fixing of the first part to a device or to a mounting element. Particularly advantageously, the connection between the first and the second part can be dismantled by plasticizing the hardened material. In particular, a fastening element (i.e. the second

pièce) pour la fixation indirecte de la première pièce peut être retirée. Ainsi par exemple il est possible de placer sur la première pièce, pour un usinage supplémentaire de celle-ci, un élément de fixation qui, de manière avantageuse, sera facilement éliminé à la fin de l'usinage de la première pièce.  part) for indirect fixing of the first part can be removed. Thus for example it is possible to place on the first part, for further machining thereof, a fixing element which, advantageously, will be easily eliminated at the end of the machining of the first part.

L'invention est décrite de manière détaillée dans ce qui suit en faisant référence aux dessins. Ceux-ci montrent : figure la à Id, quatre modes de réalisation différents de pièces assemblées ; figure 2a à 2d, quatre modes de réalisation différents de cavités en contre-dépouille, ouvertes d'un côté ; figures 3a, 3b un mode de réalisation du moyen de liaison ; figure 4, une application de deux pièces assemblées, et figure 5, un dispositif pour le moulage du matériau plastifiable.  The invention is described in detail in the following with reference to the drawings. These show: FIG. 1a to Id, four different embodiments of assembled parts; Figure 2a to 2d, four different embodiments of undercut cavities, open on one side; Figures 3a, 3b an embodiment of the connecting means; Figure 4, an application of two assembled parts, and Figure 5, a device for molding the plasticizable material.

Examinons tout d'abord les figures la à Id. Les figures la à Id montrent à titre d'exemple quatre modes de réalisation différents de pièces assemblées ; sur les figures la et 1 b, une première pièce 1 présente un trou non débouchant et une deuxième pièce 2 présente un trou débouchant, tandis que sur les figures 1 c et Id, une première pièce et une deuxième pièce présentent chacune un trou non débouchant. Le trou non débouchant et le trou débouchant dans les pièces peuvent être réalisés par perçage au laser ou par fraisage.  Let us first examine Figures 1a to Id. Figures 1a to Id show by way of example four different embodiments of assembled parts; in FIGS. 1 a and 1 b, a first part 1 has a non-through hole and a second part 2 has a through hole, while in FIGS. 1 c and Id, a first part and a second part each have a non-through hole . The non-through hole and the through hole in the parts can be made by laser drilling or by milling.

Généralement, au-dessous d'un diamètre d'environ 2 mm, l'usinage des trous, ne peut être fait que par laser. Un avantage de l'usinage par laser est la faible puissance nécessaire qui permet traitement économique. Generally, below a diameter of about 2 mm, the machining of the holes can only be done by laser. An advantage of laser machining is the low power required which allows economical processing.

Pour relier les deux pièces 1,2, on a introduit dans les trous non débouchants et les trous débouchants un matériau plastique ou plastifié, qui a ensuite durci.  To connect the two parts 1,2, a plastic or plasticized material was introduced into the non-through holes and the through holes, which then hardened.

Dans les modes de réalisation la et 1 b, le matériau durci 3, à l'extrémité des trous débouchants 3 éloignée de la surface d'assemblage des deux pièces 1, 2, forme un collet qui retient la deuxième pièce 2. Avec l'accrochage du collet combiné à la contre-dépouille du trou non débouchant on obtient une liaison par complémentarité de formes entre les deux pièces 1, 2. Dans le mode de réalisation de la figure 1 b, à la différence du mode de réalisation de la figure la, une couche 4 de matériau durci est disposée en plus entre les deux pièces 1,2. Cette couche peut servir de couche d'adhésif  In embodiments 1a and 1b, the hardened material 3, at the end of the through holes 3 remote from the assembly surface of the two parts 1, 2, forms a collar which retains the second part 2. With the attachment of the collar combined with the undercut of the non-through hole, a connection is obtained by complementarity of shapes between the two parts 1, 2. In the embodiment of FIG. 1 b, unlike the embodiment of FIG. 1a, a layer 4 of hardened material is additionally disposed between the two parts 1,2. This layer can be used as an adhesive layer

supplémentaire, dans les cas où le matériau plastique ou plastifiable durcissable est un adhésif. De même, ceci permet de maintenir un certain espace entre les deux pièces assemblées, par exemple afin d'empêcher un contact électro-conducteur. Le remplissage du trou débouchant et du trou non débouchant des pièces 1, 2 assemblées avec le matériau 3 plastique ou plastifiable durcissable a lieu de préférence par injection ou par moulage du matériau à travers le trou débouchant dans la deuxième pièce.  additional, in cases where the curable plastic or plasticizable material is an adhesive. Likewise, this makes it possible to maintain a certain space between the two assembled parts, for example in order to prevent an electrically conductive contact. The filling of the through hole and the non-through hole of the parts 1, 2 assembled with the curable plastic or plasticizable material 3 preferably takes place by injection or by molding of the material through the through hole in the second part.

Dans les modes de réalisation selon les figure 1c et Id, aussi bien la première pièce 1 que la deuxième pièce 2 ne comportent que des trous débouchants. Une liaison par complémentarité de formes est réalisée par le matériau 3 durci introduit dans les trous non débouchants en contre-dépouille.  In the embodiments according to FIGS. 1c and Id, both the first part 1 and the second part 2 only have through holes. A connection by complementarity of shapes is carried out by the hardened material 3 introduced into the non-through holes in the undercut.

Dans le mode de réalisation de la figure Id, comme dans celui de la figure lb, une couche 4 de matériau durci est placée entre les deux pièces 1,2. Le remplissage des trous non débouchants à l'aide du matériau plastique ou plastifiable peut être réalisé par moulage dudit matériau lors de l'assemblage des pièces. Une injection du matériau avec les pièces déjà assemblées exige la présence d'au moins une ouverture supplémentaire débouchant dans les trous non débouchants. In the embodiment of Figure Id, as in that of Figure 1b, a layer 4 of hardened material is placed between the two parts 1,2. The filling of non-through holes using plastic or plasticizable material can be achieved by molding said material during assembly of the parts. An injection of the material with the parts already assembled requires the presence of at least one additional opening opening into the non-opening holes.

Les figures 2a à 2d montrent à titre d'exemple quatre modes de réalisation différents de cavités en contre-dépouille ouvertes d'un côté. Dans les modes de réalisation 2a et 2b, la cavité est conformée en trou non débouchant unique à section transversale conique 5 ou rectangulaire 6. Dans les modes de réalisation des figures 2c et 2d, les deux cavités 7 sont inclinées par rapport à la surface de la pièce et sont disposées de manière symétrique, tournées de 180 , par rapport à une normale 11 à la surface de la pièce. Du fait de l'inclinaison des cavités 7 par rapport à la surface de la pièce, un matériau durcissable placé dans celles-ci est fermement ancré dans la pièce. Dans le mode de réalisation de la figure 2d, les deux cavités 8 sont disposées sur la même face de la pièce 1 et débouchent dans la surface. Une deuxième pièce 2 assemblée avec la première pièce 1 présente deux trous débouchants 10 complémentaires. Pour relier les deux pièces 1, 2, on coule ou on moule un matériau durcissable dans les trous débouchants et dans les cavités. Le matériau durci présente au niveau des extrémités des trous débouchants 10 éloignées de la surface d'assemblage des collets 12 qui retiennent la pièce 2.  Figures 2a to 2d show by way of example four different embodiments of undercut cavities open on one side. In embodiments 2a and 2b, the cavity is shaped as a single non-opening hole with a conical or rectangular cross-section 5 or 6. In the embodiments of FIGS. 2c and 2d, the two cavities 7 are inclined relative to the surface of the part and are arranged symmetrically, turned 180, with respect to a normal 11 on the surface of the part. Due to the inclination of the cavities 7 relative to the surface of the part, a hardenable material placed therein is firmly anchored in the part. In the embodiment of Figure 2d, the two cavities 8 are arranged on the same face of the part 1 and open into the surface. A second part 2 assembled with the first part 1 has two complementary through holes 10. To connect the two parts 1, 2, a hardenable material is poured or molded in the through holes and in the cavities. The hardened material has at the ends of through holes 10 remote from the assembly surface of the collars 12 which hold the part 2.

<Desc/Clms Page number 8><Desc / Clms Page number 8>

Des collets 9 similaires qui s'accrochent sur la pièce 1 sont formés au niveau des ouvertures des cavités 8. Ceux-ci renforcent la liaison par complémentarité de formes entre les deux pièces 1 et 2.  Similar collars 9 which hang on the part 1 are formed at the level of the openings of the cavities 8. These reinforce the connection by complementarity of shapes between the two parts 1 and 2.

Les figures 3a et 3b montrent un exemple de réalisation du moyen de liaison utilisable selon l'invention. Dans le mode de réalisation de la figure 3a, le moyen de liaison est formé du matériau 3 durcissable qui est moulé dans un trou non débouchant conique de la pièce 1. Le matériau 3 est muni de crochets 13 pour la liaison avec la deuxième pièce. Ceci signifie que le matériau 3, au moins aux endroits où sont prévus les crochets, est indéformable et que la plastification n'a lieu qu'à l'extrémité destinée à être moulée dans le trou non débouchant. Dans le mode de réalisation de la figure 3b, un élément de liaison sous la forme d'une tige 14 a été mis en place dans le trou non débouchant conique de la première pièce 1 avant la coulée du matériau 3 durcissable. Cette tige 14, à son extrémité insérée dans le trou non débouchant, comporte un élargissement 15 qui s'ancre dans la pièce 1. Par coulée ou par moulage du matériau durcissant 3, la tige 14 est fixée dans le trou non débouchant et, notamment, est bloquée en rotation autour de l'axe de la tige et par conséquent ne peut pas se désolidariser de la liaison par complémentarité de formes. La tige 14 peut servir de moyen de fixation pour la fixation indirecte de la pièce 1, en particulier pour un usinage complémentaire de la pièce 1.  Figures 3a and 3b show an embodiment of the connecting means used according to the invention. In the embodiment of Figure 3a, the connecting means is formed of curable material 3 which is molded in a conical non-through hole of the part 1. The material 3 is provided with hooks 13 for connection with the second part. This means that the material 3, at least in the places where the hooks are provided, is non-deformable and that the plasticization takes place only at the end intended to be molded in the non-through hole. In the embodiment of FIG. 3b, a connecting element in the form of a rod 14 has been put in place in the conical non-opening hole of the first part 1 before the casting of the hardenable material 3. This rod 14, at its end inserted in the non-through hole, has a widening 15 which is anchored in the part 1. By casting or by molding the hardening material 3, the rod 14 is fixed in the non-through hole and, in particular , is blocked in rotation around the axis of the rod and therefore cannot be detached from the connection by complementarity of shapes. The rod 14 can serve as a fixing means for the indirect fixing of the part 1, in particular for a complementary machining of the part 1.

La figure 4 montre à titre d'exemple, l'utilisation de deux pièces 1, 16 liées conformément à l'invention, la première pièce 1 étant une pièce en aluminium ou en alliage d'aluminium à anodiser et la deuxième pièce étant un support 16 du bain d'anodisation avec des moyens de contact 17 pour la pièce 1. Une liaison entre la pièce 1 et le support 16 est réalisée à l'aide d'un matériau 3 plastifiable partiellement moulé dans un trou non débouchant de la première pièce, qui est en outre pourvu de crochets 13 à des fins de fixation au support 16. En ce qui concerne la face de la pièce 1 opposée à la face connectée électriquement, il peut s'agir d'une surface décorative à anodiser, dont l'aspect ne doit pas être altéré par la liaison entre la pièce 1 et le support 16. Ceci est obtenu grâce au procédé selon l'invention.  FIG. 4 shows by way of example, the use of two parts 1, 16 linked in accordance with the invention, the first part 1 being an aluminum or aluminum alloy part to be anodized and the second part being a support 16 of the anodizing bath with contact means 17 for the part 1. A connection between the part 1 and the support 16 is made using a plasticizable material 3 partially molded in a hole not emerging from the first part , which is further provided with hooks 13 for attachment to the support 16. As regards the face of the part 1 opposite the electrically connected face, it may be a decorative surface to be anodized, the l 'aspect should not be altered by the connection between the part 1 and the support 16. This is achieved by the method according to the invention.

La figure 5 montre à titre d'exemple un dispositif pour le moulage d'un matériau 3 plastifiable durcissable dans un trou non débouchant 18 de la première pièce 1. Le dispositif comprend un tube de guidage 18, disposé à  FIG. 5 shows by way of example a device for molding a plasticizable material 3 curable in a non-through hole 18 of the first part 1. The device comprises a guide tube 18, disposed at

<Desc/Clms Page number 9><Desc / Clms Page number 9>

l'extrémité proximale dans le cas présent, pour guider le matériau 3 plastifiable, un tube de chauffage 19, disposé à l'extrémité distale dans le cas présent, pour plastifier par voie thermique le matériau 3 plastifiable, ainsi qu'un piston 20 pour refouler l'extrémité plastifiée du matériau 3 plastifiable dans le trou non débouchant 18. Le matériau 3 plastifiable est chauffé à l'aide du tube de chauffage 19, au moins juqu'à sa température de plastification, à la suite de quoi il est refoulé dans le trou non débouchant 18 par une pression axiale exercée sur le piston 20, c'est-à-dire dans la direction indiquée par la flèche. La pression axiale nécessaire est fonction du degré de plastification du matériau et elle peut être appliquée manuellement ou par des moyens mécaniques, en particulier sous la forme d'un vérin pneumatique. Le chauffage du tube de chauffage 19 peut être obtenu par un chauffage à résistances ou par un chauffage à induction.  the proximal end in the present case, to guide the plasticizable material 3, a heating tube 19, arranged at the distal end in the present case, to thermally plasticize the plasticizable material 3, as well as a piston 20 for pushing the plasticized end of the plasticizable material 3 into the non-through hole 18. The plasticizable material 3 is heated using the heating tube 19, at least up to its plasticization temperature, after which it is pushed back in the non-through hole 18 by an axial pressure exerted on the piston 20, that is to say in the direction indicated by the arrow. The axial pressure required depends on the degree of plasticization of the material and can be applied manually or by mechanical means, in particular in the form of a pneumatic cylinder. The heating of the heating tube 19 can be obtained by resistance heating or by induction heating.

En résumé, on notera que le procédé selon l'invention pour relier entre elles deux pièces, parmi lesquelles l'une au moins peut comporter une surface décorative qui ne doit pas être altérée, présente des avantages essentiels par rapport aux procédés traditionnels. Notamment par rapport à une liaison collée, le procédé selon l'invention peut être mis en oeuvre avec un nombre d'étapes plus faible et un engagement en appareils beaucoup plus réduit, ce qui permet une fabrication économique. De plus les émissions de substances polluantes sont plus faibles, ce qui constitue un avantage sur le plan écologique. Le procédé selon l'invention permet de relier par complémentarité de formes et le cas échéant également par adhérence pratiquement tous les matériaux. Une telle liaison, selon le matériau utilisé comme matériau durcissable, est stable aux intempéries et résiste à des charges élevées. Lorsqu'on utilise un adhésif, la résistance de fatigue peut être calculée de manière simple sur la base de la configuration et des paramètres du matériau, la résistance d'adhérence pouvant être calculée à partir des caractéristiques des adhésifs habituels et des couples de matériaux. Enfin, une liaison par complémentarité de formes entre deux pièces peut, si nécessaire, être démontée de manière simple par plastification d'un matériau non adhésif durcissable. In summary, it will be noted that the method according to the invention for connecting two parts together, among which at least one may have a decorative surface which must not be altered, has essential advantages compared to traditional methods. In particular compared to a bonded connection, the method according to the invention can be implemented with a lower number of steps and a much reduced commitment in devices, which allows economical manufacturing. In addition, the emissions of polluting substances are lower, which constitutes an ecological advantage. The method according to the invention makes it possible to connect by complementarity of shapes and, where appropriate, also by adhesion to practically all materials. Depending on the material used as the hardenable material, such a bond is weather-resistant and withstands high loads. When using an adhesive, the fatigue strength can be calculated in a simple manner based on the configuration and parameters of the material, the adhesion strength can be calculated from the characteristics of the usual adhesives and the pairs of materials. Finally, a connection by complementarity of shapes between two parts can, if necessary, be dismantled in a simple manner by plasticization of a curable non-adhesive material.
