Description
L’invention se rapporte au domaine technique des cycles, et en particulier à la fabrication d’accessoires pour cycles.The invention relates to the technical field of cycles, and in particular to the manufacture of accessories for cycles.
Art antérieurPrior art
Il est connu de l’art antérieur de fabriquer en grande série des accessoires pour cycles, par exemple des carters de protection ou des gardes boue pour les roues.It is known from the prior art to mass-produce accessories for cycles, for example protective casings or mudguards for the wheels.
De tels accessoires sont généralement en plastique, et obtenus par injection. Bien que cette technique de fabrication soit très rentable et répétable pour les grandes séries de fabrications, par exemple supérieures à 100 000 exemplaires, le coût des moules est très élevé et ne peut pas être amorti pour de petites séries de fabrication, par exemple inférieures à 2 000 exemplaires.Such accessories are generally made of plastic, and obtained by injection. Although this manufacturing technique is very profitable and repeatable for large manufacturing series, for example greater than 100,000 copies, the cost of the molds is very high and cannot be amortized for small manufacturing series, for example less than 2,000 copies.
Il en est de même pour les éventuelles étapes de décor de ces accessoires : ces accessoires peuvent être personnalisés en choisissant leur couleur obtenue directement dans la masse, c’est-à-dire en ajoutant des pigments avec le matériau injecter. Il s’ensuit que toute la série est fabriquée de la même couleur.The same is true for any decorating steps for these accessories: these accessories can be personalized by choosing their color obtained directly from the mass, i.e. by adding pigments with the material to be injected. It follows that the entire series is made in the same color.
Certains décors peuvent également être ajoutés au niveau des moules, par exemple un marquage en relief, représentant un texte ou un logo, ou encore une texturation différente sur certaines zones de l’accessoire, tel que des zones lisses et des zones dépolies. Là encore, les décors seront communs à tous les exemplaires des accessoires fabriqués, car ils sont obtenus directement à partir du moule d’injection.Certain decorations can also be added to the moulds, for example raised marking, representing a text or a logo, or even a different texturing on certain areas of the accessory, such as smooth areas and frosted areas. Here again, the decorations will be common to all the copies of the accessories manufactured, because they are obtained directly from the injection mold.
Il existe enfin des techniques d’étiquetage en moule, en anglais « in mold labelling », dans lesquelles le décor des pièces est déposé dans le moule d’une pièce avant son injection. Là encore, l’utilisation d’un moule n’est pas adapté aux petites séries.Finally, there are in-mold labeling techniques, in English "in mold labelling", in which the decoration of the parts is deposited in the mold of a part before its injection. Again, the use of a mold is not suitable for small series.
L’un des buts de l’invention est de pallier les inconvénients de l’art antérieur, en proposant un processus de fabrication qui soit aussi bien adapté aux grandes séries, qu’aux petites séries voir aux séries unitaires.One of the aims of the invention is to overcome the drawbacks of the prior art, by proposing a manufacturing process which is equally well suited to large series, to small series or even to unit series.
À cet effet, il a été mis au point un procédé de fabrication d’un accessoire pour cycle, tel qu’un garde boue ou un carter de protection.To this end, a process for manufacturing a cycle accessory, such as a mudguard or a protective casing, has been developed.
Selon l’invention, il comprend une étape de découpe de l’accessoire dans une feuille ou une plaque de matière, la découpe étant réalisée selon une technique de suivi de profil.According to the invention, it comprises a step of cutting the accessory out of a sheet or a plate of material, the cutting being carried out using a profile tracking technique.
De cette manière, le processus de fabrication s’affranchit de l’utilisation d’un moule, ce qui signifie que chaque série fabriquée peut avoir sa propre forme, ou encore son propre choix de matériau utilisé avec des finitions particulières. Il est même envisageable de personnaliser les accessoires de façon unitaire, en adaptant la découpe à chaque exemplaire fabriqué.In this way, the manufacturing process is freed from the use of a mould, which means that each series manufactured can have its own shape, or even its own choice of material used with particular finishes. It is even possible to customize the accessories individually, by adapting the cut to each manufactured copy.
Selon une forme de réalisation particulière, l’étape de découpe par suivi de profil est réalisée par fraisage numérique. Cette méthode est peu onéreuse et est adaptée aux matériaux sous forme de feuilles ou de plaques.According to a particular embodiment, the step of cutting by profile tracking is carried out by digital milling. This method is inexpensive and suitable for materials in the form of sheets or plates.
Avantageusement, le procédé comprend également une étape de décor de l’accessoire découpé, ce qui permet de perfectionner la personnalisation.Advantageously, the method also includes a step of decorating the cut-out accessory, which makes it possible to improve the personalization.
Afin d’être compatible avec les outils de production numériques, et en particulier la gestion de données variables, l’étape de décor est réalisée par une impression jet d’encre dite « goutte à la demande », avec une encre à séchage aux rayons ultraviolet.In order to be compatible with digital production tools, and in particular the management of variable data, the decoration stage is carried out by so-called "drop-on-demand" inkjet printing, with ray-drying ink. ultraviolet.
Pour protéger l’état de surface de l’accessoire, et en particulier du décor le cas échéant, le procédé comprend en outre une étape de protection du décor ou du matériau dans son ensemble, tel qu’un dépôt de vernis.To protect the surface condition of the accessory, and in particular of the decoration if applicable, the method further comprises a step of protecting the decoration or the material as a whole, such as a deposit of varnish.
Dans certains modes de réalisation, le procédé comprend également une étape de mise en forme de l’accessoire découpé, par exemple par cintrage et/ou roulage. Ainsi, l’accessoire est adapté en forme à l’esthétique souhaitée ou à la géométrie du cycle destinée à recevoir l’accessoire.In certain embodiments, the method also comprises a step of shaping the cut-out accessory, for example by bending and/or rolling. Thus, the accessory is adapted in shape to the desired aesthetics or to the geometry of the cycle intended to receive the accessory.
Dans ces modes, le procédé comprend avantageusement également une étape de rainurage d’une face interne de l’accessoire, préalable à l’étape de mise en forme. Ce rainurage permet de faciliter la mise en forme de l’accessoire. S’il y a un décor, ses déformations sont minimisées car l’épaisseur du matériau mis en forme est réduite.In these modes, the method advantageously also comprises a step of grooving an internal face of the accessory, prior to the shaping step. This grooving makes it easier to shape the accessory. If there is a decor, its deformations are minimized because the thickness of the shaped material is reduced.
De préférence, la matière de l’accessoire est un complexe d’une première et une deuxième feuilles d’aluminium d’épaisseur comprise entre 0,2 et 0,8mm prenant en sandwich une feuille réalisée en matériau plastique, d’épaisseur comprise entre 0,5 et 5mm. Ce matériau présente de bonnes performances de durabilité, de résistance aux intempéries, est peu onéreux, et est simple à mettre en œuvre.Preferably, the material of the accessory is a complex of a first and a second sheet of aluminum with a thickness of between 0.2 and 0.8 mm sandwiching a sheet made of plastic material, with a thickness of between 0.5 and 5mm. This material has good performance in terms of durability, weather resistance, is inexpensive, and is simple to implement.
Dans certains modes de réalisation, l’accessoire est un garde-boue ou un carter de protection.In some embodiments, the accessory is a fender or a protective cover.
