Description
L'invention concerne un procédé d'obtention d'une cale pelable tridimensionnelle ainsi que la cale pelable tridimensionnelle obtenue par ce procédé.The invention relates to a method for obtaining a three-dimensional peelable wedge and the three-dimensional peelable wedge obtained by this method.
Actuellement, les cales pelables sont formées à partir d'un empilement de feuilles des matériaux entre lesquels une couche d'adhésif permet de maintenir les feuilles ensemble. Toutefois, l'empilement des feuilles, et donc la cale, reste plan, c'est-à-dire que chacune des feuilles de l'empilement forme un plan et que l'ensemble des feuilles sont parallèles les unes aux autres. De telles cales pelables sont décrites dans les documents FR 2 716 138 et FR 2 831 095 par exemple. D'autre part, il existe des cales dont l'empilement est agencé de sorte à permettre de réaliser des épaisseurs différentes à des endroits différents de la cale. Une telle cale est décrite par exemple dans le document EP 2 329 546. Toutefois ces cales à épaisseurs multiples restent des cales dont les empilements sont plans et les surfaces de contact sont, par conséquent, planes elles aussi. Cependant, il y a des situations qui nécessitent de réaliser un calage entre des pièces dont les surfaces en contact ne sont pas planes. Par exemple, dans le cas de l'agencement de deux pièces à surface conique l'une avec l'autre. Par conséquent, il est apparu un besoin de réaliser ou d'obtenir des cales dont l'épaisseur reste ajustable par pelage permettant de réaliser ce type de calage.Currently, the peelable shims are formed from a stack of sheets of materials between which an adhesive layer keeps the sheets together. However, the stack of sheets, and therefore the wedge, remains flat, that is to say that each of the sheets of the stack forms a plane and that all the sheets are parallel to each other. Such peelable shims are described in documents FR 2 716 138 and FR 2 831 095 for example. On the other hand, there are shims whose stack is arranged to allow to achieve different thicknesses at different locations of the hold. Such a shim is described for example in EP 2 329 546. However, these shims multiple thicknesses remain wedges whose stacks are planar and the contact surfaces are, therefore, also planes. However, there are situations that require wedging between parts whose surfaces in contact are not flat. For example, in the case of the arrangement of two conical surface parts with each other. Therefore, it has emerged a need to make or obtain wedges whose thickness remains adjustable by peeling to achieve this type of wedging.
Un but de l'invention est de fournir un procédé qui permet d'obtenir des cales pelables tridimensionnelles permettant de caler entre elles deux surfaces en contact qui ne sont pas planes. A cet effet, il est prévu, selon l'invention, un 5 procédé d'obtention d'une cale pelable tridimensionnelle comportant au moins deux parties comportant des étapes de : réalisation d'une série d' au moins deux empilements alternant des feuilles de matériau et des 10 couches d'adhésif, chaque empilement étant associé à une partie de la cale pelable tridimensionnelle à obtenir ; - mise en place de chacun des empilements de la série d'au moins deux empilements dans un moule de forme correspondant à la partie de la cale pelable 15 tridimensionnelle à obtenir ; - polymérisation de chacun des empilements de la série d'au moins deux empilements au sein du moule de forme associé, puis démoulage ; - préparation des bords destinés à être aboutés 20 des empilements ainsi formés; et, - assemblage par aboutement les uns avec les autres des empilements ainsi formés de la série d'au moins deux empilements pour obtenir la cale pelable tridimensionnelle. 25 Avantageusement, mais facultativement, le procédé selon l'invention présente au moins l'une des caractéristiques supplémentaires suivantes : - lors de l'étape d'assemblage, une feuille 30 encollée de matériau est positionnée à cheval sur deux empilements formés aboutés l'un avec l'autre sur une surface interne de la cale pelable tridimensionnelle ; - lors de l'étape de préparation, au moins une feuille de matériau formant une partie d'une surface interne de la cale tridimensionnelle forme une languette s'étendant en saillie depuis au moins un des bords destinés à être aboutés des empilements ainsi formés ; - lors de l'étape d'assemblage, la languette est positionnée sur l'empilement ainsi formé abouté avec l'empilement ainsi formé comprenant la languette ; et, - lors de l'étape d'assemblage, un adhésif est 10 utilisé et comporte une résine polymérisable à température ambiante. Il est prévu aussi, selon l'invention, une cale pelable tridimensionnelle réalisée selon un procédé 15 d'obtention présentant au moins l'une des caractéristiques techniques précédentes, la cale pelable tridimensionnelle étant creuse. Avantageusement, mais facultativement, la cale 20 selon l'invention présente au moins l'une des caractéristiques supplémentaires suivantes : - la cale est de forme conique ; - la cale est en deux parties, chaque partie étant obtenue à partir d'un empilement ainsi formé ; et, 25 - les deux parties sont symétriques l'une de l'autre selon un plan passant par les bords destinés à être aboutés. D'autres caractéristiques et avantages de 30 l'invention apparaîtront lors de la description ci-après d'un mode de réalisation de l'invention. Aux dessins annexés : - la figure 1 est une vue tridimensionnelle éclatée d'une cale pelable tridimensionnelle obtenue par le procédé selon l'invention ; - la figure 2 est une vue de côté de la cale 5 pelable tridimensionnelle de la figure 1 ; - la figure 3 est une vue en section de la cale tridimensionnelle pelable de la figure 1 ; - la figure 4 est une vue en section d'une variante de réalisation de la cale pelable tridimensionnelle de la 10 figure 1 ; - la figure 5 est une vue tridimensionnelle d'une cale pelable tridimensionnelle selon l' invention présentant une forme différente. 15 En référence aux figures 1 à 4, nous allons décrire une cale pelable tridimensionnelle de forme conique creuse. Cette forme de la cale pelable tridimensionnelle selon l'invention est choisie, ici, à but purement illustratif. Le procédé d'obtention d'une telle cale 20 pelable tridimensionnelle selon l'invention peut s'appliquer à tout type et forme de cales pelables tridimensionnelles. La cale pelable tridimensionnelle 1 selon 25 l'invention est donc ici de forme conique creuse. Elle est réalisée par aboutement de plusieurs parties 10, 20, ici au nombre de deux. Il est à noter que le choix du nombre de parties constituant la cale pelable tridimensionnelle à obtenir est fonction de la complexité 30 de la forme de la cale pelable tridimensionnelle. En effet, comme nous le verrons plus loin, chaque partie formant la cale pelable tridimensionnelle à obtenir est réalisée à l'aide d'un moule de forme, et doit donc être démoulable facilement. Dans le cas de la cale pelable tridimensionnelle illustrée en figure 1, les deux parties 10 et 20 formant la cale pelable tridimensionnelle 1 sont identiques et symétriques l'une par rapport à l'autre selon un plan passant par des bords 13,14, 23,24. La première partie 10 est réalisée à partir d'un premier empilement de feuilles de matériau, comme des feuilles métalliques, comme l'acier inoxydable ou l'aluminium, ou encore des feuilles de matériau composite. Entre chacune des feuilles composant ce premier empilement, est réalisée une couche d'adhésif qui va permettre de maintenir les feuilles assemblées les unes aux autres tout en permettant, lors d'une utilisation de la cale pelable tridimensionnelle 1 selon l'invention, un ajustement de l'épaisseur par délitage de une ou plusieurs feuilles des matériaux empilés. La première partie 10 comporte une face interne 12 réalisée par une feuille de matériau et une face externe 11 elle-même réalisée par une autre feuille de matériau, les deux feuilles de matériau étant à chacune des extrémités de l'empilement formant la première partie 10. De manière symétrique, la deuxième partie 20 est réalisée à partir d'un deuxième empilement similaire de feuilles de matériau alternant avec des couches d'adhésif. La deuxième partie 20 présente une face interne 22 réalisée par une feuille de matériau et une face externe 21 réalisée par une autre feuille de matériau, les deux feuilles de matériau étant chacune à une extrémité de l'empilement formant la deuxième partie 20. Afin de réaliser chacune des parties 10 et 20, le procédé d'obtention d'une cale pelable tridimensionnelle 1 selon l'invention comporte une première étape de réalisation des empilements, de manière connue en soi, qui consiste à réaliser un empilement alterné de feuilles de matériau et de couches d'un matériau adhésif. Chaque 5 feuille présente une résistance intrinsèque au déchirement et chaque couche de matériau adhésif relie l'une à l'autre deux feuilles adjacentes de l'empilement par une force de liaison plus faible que la résistance de feuilles au déchirement, selon qu'il résulte que chaque 10 feuille peut être détachée de l'empilement sans se déchirer. Une fois les empilements réalisés, chacun de ces empilements est positionné dans un moule de forme correspondant à la partie désirée de la cale pelable 15 tridimensionnelle 1 à obtenir. Ensuite, le moule subit un cycle de cuisson permettant de polymériser le matériau adhésif situé entre les feuilles de matériau de l'empilement alors que ce dernier est mis en compression au sein du moule de forme. 20 Une fois le procédé de cuisson réalisé, une étape de démoulage est réalisée suivie d'un arasement des chutes non nécessaires de l'empilement permettant entre autres de réaliser des bords d'aboutement 13 et 14 pour ce qui concerne la première partie 10, 23 et 24 pour ce 25 qui concerne la deuxième partie 20. En effet, ces bords doivent être bien préparés puisque ces derniers vont être aboutés par paire l'un à l'autre, lors de l'assemblage des différentes parties 10,20 formant la cale pelable tridimensionnelle 1 selon l'invention. De manière 30 générale, cet arasement des chutes permet de finaliser les parties 10,20 avant assemblage de la cale pelable tridimensionnelle 1 selon l'invention.An object of the invention is to provide a method which makes it possible to obtain three-dimensional peelable wedges making it possible to wedge between them two surfaces in contact which are not flat. To this end, according to the invention, there is provided a method for obtaining a three-dimensional peelable shim comprising at least two parts comprising steps of: producing a series of at least two stacks alternating sheets of material and layers of adhesive, each stack being associated with a portion of the three-dimensional peelable wedge to be obtained; placing each of the stacks of the series of at least two stacks in a mold of shape corresponding to the part of the three-dimensional peelable wedge to be obtained; polymerization of each of the stacks of the series of at least two stacks in the mold of associated shape, then demolding; preparation of the edges intended to be joined with the stacks thus formed; and, assembling by abutment with one another the stacks thus formed of the series of at least two stacks to obtain the three-dimensional peelable shim. Advantageously, but optionally, the method according to the invention has at least one of the following additional features: - during the assembly step, a sheet 30 bonded with material is positioned astride two formed butted stacks; with each other on an inner surface of the three-dimensional peelable shim; during the preparation step, at least one sheet of material forming a part of an inner surface of the three-dimensional wedge forms a tab projecting from at least one of the edges intended to be abutted with the stacks thus formed; during the assembly step, the tongue is positioned on the stack thus formed abutting with the thus formed stack comprising the tongue; and, during the assembly step, an adhesive is used and comprises a polymerizable resin at room temperature. According to the invention, there is also provided a three-dimensional peelable shim made according to a production method having at least one of the preceding technical characteristics, the three-dimensional peelable shim being hollow. Advantageously, but optionally, the wedge 20 according to the invention has at least one of the following additional features: the wedge is of conical shape; the wedge is in two parts, each part being obtained from a stack thus formed; and, the two parts are symmetrical to each other in a plane passing through the edges intended to be abutted. Other features and advantages of the invention will become apparent from the following description of an embodiment of the invention. In the accompanying drawings: FIG. 1 is an exploded three-dimensional view of a three-dimensional peelable shim obtained by the process according to the invention; Figure 2 is a side view of the three-dimensional peelable shim of Figure 1; FIG. 3 is a sectional view of the peelable three-dimensional wedge of FIG. 1; FIG. 4 is a sectional view of an alternative embodiment of the three-dimensional peelable shim of FIG. 1; - Figure 5 is a three-dimensional view of a three-dimensional peelable shim according to the invention having a different shape. With reference to Figures 1 to 4, we will describe a three-dimensional peelable wedge of hollow conical shape. This form of the three-dimensional peelable wedge according to the invention is chosen here for purely illustrative purposes. The method for obtaining such a three-dimensional peelable shim according to the invention can be applied to any type and form of three-dimensional peelable shims. The three-dimensional peelable shim 1 according to the invention is therefore here of hollow conical shape. It is made by abutting several parts 10, 20, here two in number. It should be noted that the choice of the number of parts constituting the three-dimensional peelable shim to obtain is a function of the complexity of the shape of the three-dimensional peelable shim. Indeed, as we will see later, each part forming the three-dimensional peelable wedge to be obtained is made using a form mold, and must be easily demoldable. In the case of the three-dimensional peelable shim illustrated in FIG. 1, the two parts 10 and 20 forming the three-dimensional peelable shim 1 are identical and symmetrical with respect to one another in a plane passing through edges 13, 14, 23 24. The first part 10 is made from a first stack of sheets of material, such as metal sheets, such as stainless steel or aluminum, or sheets of composite material. Between each of the sheets making up this first stack, an adhesive layer is produced which will make it possible to hold the assembled sheets together while at the same time allowing, when using the three-dimensional peelable shim 1 according to the invention, an adjustment the thickness by disintegration of one or more sheets of stacked materials. The first part 10 has an inner face 12 made of a sheet of material and an outer face 11 itself made of another sheet of material, the two sheets of material being at each end of the stack forming the first part 10 Symmetrically, the second portion 20 is made from a second, similar stack of alternating material sheets with layers of adhesive. The second portion 20 has an inner face 22 made of a sheet of material and an outer face 21 made of another sheet of material, the two sheets of material being each at one end of the stack forming the second part 20. In order to each of the parts 10 and 20, the method for obtaining a three-dimensional peelable shim 1 according to the invention comprises a first step of making the stacks, in a manner known per se, which consists in producing an alternating stack of sheets of material and layers of an adhesive material. Each sheet has intrinsic tear strength and each layer of adhesive material connects two adjacent sheets of the stack to one another by a lower bond strength than the sheet tear strength, as a result of which that each sheet can be detached from the stack without tearing. Once the stacks have been made, each of these stacks is positioned in a mold of shape corresponding to the desired part of the three-dimensional peelable shim 1 to be obtained. Then, the mold undergoes a firing cycle for polymerizing the adhesive material between the sheets of material of the stack while the latter is compressed into the form mold. Once the cooking process has been carried out, a demoulding step is carried out followed by a leveling off of the unnecessary drops in the stack making it possible, among other things, to make abutment edges 13 and 14 with respect to the first part 10, 23 and 24 for the second part 20. Indeed, these edges must be well prepared since the latter will be abutted in pairs to one another, during the assembly of the various parts 10,20 forming the three-dimensional peelable shim 1 according to the invention. In general, this leveling of the falls makes it possible to finalize the parts 10, 20 before assembly of the three-dimensional peelable shim 1 according to the invention.
Lors de l'assemblage des différentes parties 10, 20 afin d'obtenir la cale pelable tridimensionnelle 1 selon l'invention, une couche 30 de matériau adhésif est prévue sur les bords d'aboutement 14, 24 et 13, 23. Le matériau 5 adhésif de la couche 30 est par exemple une résine qui est polymérisable à température ambiante. L'utilisation d'une telle résine évite de repasser la cale pelable tridimensionnelle 1 selon l'invention dans un cycle de cuisson pour polymériser la couche 30de matériau adhésif. 10 En effet, dans cette situation, il y aurait un risque de modifier la mise en forme et l'empilement des différentes parties 10, 20 formant la cale pelable tridimensionnelle 1 selon l'invention. Afin d'assurer le bon assemblage de différentes 15 parties 10, 20 formant la cale pelable tridimensionnelle 1 selon l'invention, il est prévu de positionner une feuille d'assemblage 40 qui est collée à l'aide du matériau adhésif formant la couche 30 sur la face interne 12, 22 des différentes parties formant la cale pelable 20 tridimensionnelle 1 selon l'invention. Cette configuration est illustrée à la figure 3. Dans ce cas, la feuille 40 est réalisée dans le même matériau que les feuilles de matériau formant les empilements qui ont été formés pour obtenir les différentes parties 10, 20 de la 25 cale pelable tridimensionnelle 1 selon l'invention. De plus, cette feuille 30 est positionnée de sorte à se retrouver à cheval sur les deux parties 10, 20 au niveau de leurs bords respectifs qui ont été aboutés l'un avec l'autre. 30 Dans une variante de réalisation, illustrée à la figure 4, la feuille de matériau 40 servant à renforcer l'assemblage des parties 10,20 formant la cale pelable tridimensionnelle 1 selon l'invention est remplacée par des languettes 15, 25 réalisées à partir d'au moins la feuille de matériau de l'empilement réalisant la surface interne 12, 22 des parties 10, 20 respectivement, formant la cale pelable tridimensionnelle 1 selon l'invention. Une fois les bords d'aboutement 13, 14 et 23, 24 réalisés, les languettes 15, 25 s'étendent en saillie depuis au moins un des bords 13, 24 d'aboutement. Ainsi, lors de l'assemblage des parties 10, 20 formant la cale pelable tridimensionnelle 1 selon l'invention, ces dernières sont emboîtées les unes avec les autres lors de la mise en contact des bords d'aboutement des parties 10, 20 ainsi assemblées. De nouveau, un matériau adhésif formant la couche 30 est utilisé comme précédemment pour l'assemblage. De préférence, les languettes 15, 25 présentent une forme correspondant à une partie d'un développé de la surface interne de l'autre partie sur laquelle ladite languette 15, 25 est destinée à être collée. D'autre part, une forme complémentaire est retirer de la face interne de la partie sur laquelle la languette va être collé afin qu'il n'y ait pas de variation de l'épaisseur de la cale pelable tridimensionnelle 1 selon l'invention entre la face interne 12,22 et la face externe 11,21.When assembling the various parts 10, 20 to obtain the three-dimensional peelable shim 1 according to the invention, a layer 30 of adhesive material is provided on the abutment edges 14, 24 and 13, 23. The material 5 Adhesive of the layer 30 is for example a resin which is polymerizable at room temperature. The use of such a resin avoids ironing the three-dimensional peelable shim 1 according to the invention in a firing cycle to polymerize the layer 30 of adhesive material. Indeed, in this situation, there would be a risk of modifying the shaping and stacking of the various parts 10, 20 forming the three-dimensional peelable shim 1 according to the invention. In order to ensure the proper assembly of different parts 10, 20 forming the three-dimensional peelable shim 1 according to the invention, it is intended to position an assembly sheet 40 which is glued with the aid of the adhesive material forming the layer 30. on the inner face 12, 22 of the different parts forming the three-dimensional peelable shim 1 according to the invention. This configuration is illustrated in FIG. 3. In this case, the sheet 40 is made of the same material as the sheets of material forming the stacks which have been formed to obtain the different parts 10, 20 of the three-dimensional peelable shim 1 according to FIG. the invention. In addition, this sheet 30 is positioned so as to be straddling the two portions 10, 20 at their respective edges which have been abutted with each other. In an alternative embodiment, illustrated in FIG. 4, the sheet of material 40 serving to reinforce the assembly of the parts 10, 20 forming the three-dimensional peelable shim 1 according to the invention is replaced by tabs 15, 25 made from at least the sheet of material of the stack forming the inner surface 12, 22 of the parts 10, 20 respectively, forming the three-dimensional peelable shim 1 according to the invention. Once the abutment edges 13, 14 and 23, 24 are made, the tabs 15, 25 project from at least one of the abutment edges 13, 24. Thus, during the assembly of the parts 10, 20 forming the three-dimensional peelable shim 1 according to the invention, the latter are nested with each other when the abutting edges of the parts 10, 20 thus assembled are brought into contact. . Again, an adhesive material forming layer 30 is used as previously for assembly. Preferably, the tongues 15, 25 have a shape corresponding to a part of a developed of the inner surface of the other part on which said tongue 15, 25 is intended to be glued. On the other hand, a complementary shape is removed from the inner face of the part on which the tongue will be glued so that there is no variation in the thickness of the three-dimensional peelable shim 1 according to the invention between the inner face 12,22 and the outer face 11,21.
Le procédé d'obtention selon l'invention d'une cale pelable tridimensionnelle 1 selon l'invention vient d'être décrit en regard d'une cale pelable tridimensionnelle 1 de forme tronconique creuse.The process according to the invention for obtaining a three-dimensional peelable shim 1 according to the invention has just been described with regard to a three-dimensional peelable shim 1 of hollow frustoconical shape.
Toutefois, comme cela est illustré en figure 5, la cale peut être de forme quelconque comme par exemple présenter une forme hexagonale 2 en section. D'autres formes peuvent être réalisées à l'aide du procédé d'obtention selon l'invention comme par exemple une cale de section ovoïde ou de toute autre forme polygonale en section. De plus, les cales pelables tridimensionnelles selon l'invention réalisées par le procédé d'obtention de 5 l'invention peuvent être tronconiques dans leur forme générale ou bien de forme régulière de type cylindrique ou encore de forme quelconque avec des dimensions de section pouvant varier le long d'un axe longitudinal principal de la cale pelable tridimensionnelle à obtenir 10 avec le procédé d'obtention de l'invention. Bien entendu il est possible d'apporter des modifications à l'invention sans pour autant sortir du cadre de celle-ci. 15However, as illustrated in FIG. 5, the shim can be of any shape, for example having a hexagonal shape 2 in section. Other forms can be made using the method of obtaining according to the invention such as a wedge of ovoid section or other polygonal shape in section. In addition, the three-dimensional peelable shims according to the invention produced by the process for obtaining the invention may be frustoconical in their general shape or of regular cylindrical type or of any shape with varying sectional dimensions. along a main longitudinal axis of the three-dimensional peelable wedge to be obtained with the method of obtaining the invention. Of course it is possible to make modifications to the invention without departing from the scope thereof. 15
