Abstract
Description
La présente invention a pour objet un procédé de fabrication d'une boite de montre dont l'intérieur de la carrure présente une partie en matière synthétique, ainsi qu'une boîte obtenue par ce procédé. La boîte peut être en une ou deux pièces, ronde ou de forme.The present invention relates to a method of manufacturing a watch case, the interior of the middle part having a synthetic material part, as well as a box obtained by this process. The box can be in one or two pieces, round or shaped.
En vue de la fixation de la glace, de la fixation du cadran et du mouvement, et, dans le cas de boites à fond rapporté, en vue de la fixation du fond, il est nécessaire que les cotes des faces intérieures de la carrure soient tenues de façon très précise et que l'état des surfaces soit très bien fini. Or ceci ne s'obtient qu'au prix de reprises telles que tournage, fraisage, rectifiage ou étampage successifs. Dans le cas de boites de forme à ouverture de forme ces reprises sont particulièrement difficiles et coûteuses. Malgré ces reprises il est en outre nécessaire de prévoir des garnitures d'étanchéité entre la carrure, respectivement la carrure-lunette, et la glace, d'une part, et entre le fond et la carrure, d'autre part.For the fixing of the crystal, the fixing of the dial and the movement, and, in the case of boxes with added back, for the fixing of the back, it is necessary that the dimensions of the inner faces of the middle are held very precisely and that the condition of the surfaces is very well finished. However, this is only obtained at the cost of repetitions such as successive turning, milling, rectification or stamping. In the case of shape boxes with shape opening, these times are particularly difficult and expensive. Despite these occasions, it is also necessary to provide seals between the middle part, respectively the middle-bezel, and the crystal, on the one hand, and between the back and the middle, on the other hand.
On a déjà proposé de revêtir par surmoulage l'intérieur d'une carrure-lunette d'une matière plastique souple et compressible destinée à venir maintenir la glace et le fond-carrure par adhérence et compression. Il est connu toutefois que la matière plastique surmoulée intérieurement a tendance à se décoller par retrait de son support. C'est pourquoi l'ancrage radial est assuré dans ce cas par un profil en queue d'aronde usiné dans la carrure-lunette.It has already been proposed to coat, by overmolding, the inside of a middle part of the bezel with a flexible and compressible plastic material intended to hold the crystal and the back part by adhesion and compression. It is known, however, that the plastic molded on the inside tends to peel off by removing its support. This is why the radial anchoring is ensured in this case by a dovetail profile machined in the middle part.
La présente invention a pour but de supprimer tout usinage de reprise de la surface intérieure de la carrure par un revêtement en matière synthétique destiné à absorber les irrégularités de surface et dont l'élasticité est destinée à absorber les différences de dimensions entre la carrure, d'une part, et le fond et la glace, d'autre part, de manière à permettre une fixation étanche des éléments de la boîte sans garniture de joint auxiliaire. Le revêtement en matière synthétique est de préférence relativement dur, par exemple 90 shore, de manière à assurer une très bonne retenue.The present invention aims to eliminate any machining of the interior surface of the middle part by a coating of synthetic material intended to absorb surface irregularities and whose elasticity is intended to absorb the differences in dimensions between the middle part, d 'on the one hand, and the bottom and the glass, on the other hand, so as to allow a tight fixing of the elements of the box without an auxiliary gasket. The coating of synthetic material is preferably relatively hard, for example 90 shore, so as to ensure very good retention.
Le procédé selon l'invention est caractérisé en ce que l'on usine grossièrement l'intérieur de la carrure, qu'on nettoie la surface ainsi usinée, qu'on revêt la surface nettoyée d'un agent organique liquide adhérant à la surface métallique et aux polymères organiques et qu'on revêt, par surmoulage, la surface ainsi préparée d'une matière synthétique constituée par un polymère organique.The method according to the invention is characterized in that the interior of the middle part is roughly machined, that the surface thus machined is cleaned, that the cleaned surface is coated with a liquid organic agent adhering to the metal surface and organic polymers and which the surface thus prepared is coated by overmolding of a synthetic material consisting of an organic polymer.
Ce procédé permet d'utiliser des carrures dont l'intérieur est brut d'étampage, de dimensions et de forme standard, dans des tolérances très larges. La matière synthétique absorbe sans autre les variations de cote et les irrégularités de surface. La précision qu'il est possible d'obtenir en ce qui concerne les cotes de la matière synthétique surmoulée permet sans autre de conformer cette matière, au moyen d'empreintes, de telle manière qu'elle assure un joint étanche avec la glace et avec le fond sans qu'il soit nécessaire de prévoir une garniture d'étanchéité de ces joints. Il est en outre sans autre possible de former la matière synthétique surmoulée de manière à ce qu'elle assure la fonction de cercle d'agrandissement ou de support d'encageage.This process makes it possible to use shoulders whose interior is roughly stamped, of standard dimensions and shape, within very wide tolerances. The synthetic material absorbs dimension variations and surface irregularities without further ado. The precision which it is possible to obtain with regard to the dimensions of the overmolded synthetic material makes it possible without other to conform this material, by means of impressions, in such a way that it ensures a tight seal with the glass and with the bottom without the need to provide a seal for these joints. It is furthermore without other possibility to form the overmolded synthetic material so that it performs the function of enlargement circle or casing support.
Le dessin annexé représente, à titre d'exemple, quelques formes d'exécution de l'invention.The accompanying drawing shows, by way of example, some embodiments of the invention.
- La figure 1 représente une vue en coupe axiale d'une boite de montre, qui pourrait aussi bien être une boite ronde qu'une boîte de forme.Figure 1 shows an axial sectional view of a watch case, which could just as easily be a round case as a shaped case.
- La figure 2 représente une vue en coupe axiale d'une carrure selon une seconde forme d'exécution.Figure 2 shows an axial sectional view of a middle part according to a second embodiment.
- La figure 3 représente une coupe axiale d'une carrure selon une troisième forme d'exécution.Figure 3 shows an axial section of a middle part according to a third embodiment.
- La figure 4 représente une coupe axiale d'une carrure selon une quatrième forme d'exécution.Figure 4 shows an axial section of a middle part according to a fourth embodiment.
La boîte représentée à la figure 1 est constituée d'une carrure-lunette 1, d'un fond rapporté à pression 2. et d'une glace 3. Elle abrite un mouvement 4 représenté schématiquement. On a représenté en pointillés l'emplacement d'un organe de commande 5 pour la tige duquel a été prévu un passage dans la carrure. L'intérieur de la carrure est revêtu d'une matière synthétique 7, thermo-durcissable ou thermo-plastique ou élastomère, par exemple du chlorure de polyvinyle dur, du polyéthylène, du prolypropylène, un polyamide ou un caoutchouc synthétique ou naturel. La matière synthétique présente une dureté relativement élevée comprise entre 80 et 100 shore, de préférence 90 shore. La partie supérieure 7a de la matière synthétique constitue un cran de glace dans lequel est fixée de manière étanche la glace 3. De même, la partie inférieure 7b de cette matière synthétique assure un joint étanche entre le fond 2 et la carrure 1. La partie 7c forme un réhaut contre lequel vient s'appuyer le cadran 8.The box shown in Figure 1 consists of a middle-bezel 1, a press-fitted back 2. and a crystal 3. It houses a movement 4 shown schematically. There is shown in dotted lines the location of a
Pour obtenir une telle boîte on procède de la manière suivante : on usine grossièrement l'intérieur de la carrure 1, par exemple par étampage, puis on nettoie parfaitement la surface intérieure de la carrure et l'on revêt celle-ci d'un agent organique liquide destiné à assurer l'adhérence de la matière synthétique au métal. Ensuite, on revêt cette surface de matière synthétique 7 par surmoulage, par exemple par thermo- moulage au moyen d'empreintes, selon une technique connue, et on donne à la partie en matière synthétique 7 la forme intérieure désirée. Après démoulage l'intérieur de la carrure est laissé tel quel. L'extérieur de la carrure est terminé selon les méthodes usuelles, avant ou après le surmoulage, selon les cas.To obtain such a box, the procedure is as follows: the interior of the middle part 1 is roughly machined, for example by stamping, then the interior surface of the middle part is thoroughly cleaned and the latter is coated with an agent organic liquid intended to ensure the adhesion of the synthetic material to the metal. Next, this surface of synthetic material 7 is coated by overmolding, for example by thermo-molding by means of impressions, according to a known technique, and the plastic part 7 is given the desired interior shape. After release from the mold laughing is left as is. The exterior of the middle part is finished according to the usual methods, before or after overmolding, as the case may be.
Le procédé de fabrication sera illustré par quelques exemples.The manufacturing process will be illustrated by a few examples.
On procède à un premier nettoyage de la carrure brute au moyen d'ultrasons dans un bain de perchloréthylène.The raw build is first cleaned by ultrasound in a perchlorethylene bath.
On procède ensuite à un nettoyage chimique en immergeant la carrure dans un bain d'oxydes d'alcalis dilués avec de l'eau et chauffé à une température de 90 o C. A chemical cleaning is then carried out by immersing the middle part in a bath of alkali oxides diluted with water and heated to a temperature of 90 o C.
On applique ensuite, au pinceau ou au pistolet, un mélange de xylène et de perchloréthylène sur la surface intérieure de la carrure, puis on procède au surmoulage de chlorure de polyvinyle dur.A mixture of xylene and perchlorethylene is then applied, using a brush or a spray gun, to the inner surface of the middle part, followed by overmolding of hard polyvinyl chloride.
On nettoie la carrure brute d'étampage aux ultrasons dans du trichlorétylène, puis on procède à un nettoyage chimique comme dans l'exemple I.The raw middle part of the stamping is cleaned by ultrasound in trichlorethylene, then a chemical cleaning is carried out as in Example I.
Ensuite, on applique, au pinceau ou au pistolet, un mélange de méthyl et d'isobutylcétone éther de glycol puis on procède au surmoulage du polymère organique.Then, a mixture of methyl and isobutyl ketone glycol ether is applied, using a brush or a spray gun, and the organic polymer is then overmolded.
On nettoie la surface de la carrure comme dans l'exemple I ou II, puis on applique, au pinceau ou au pistolet, un mélange de méthyl et d'éthylcétone/xy- lène, puis on procède au surmoulage du polymère organique.We clean the surface of the middle as in Example I or II, then a mixture of methyl and ethyl ketone / xylene is applied with a brush or a spray gun, followed by overmolding of the organic polymer.
Selon une deuxième forme d'exécution représentée à la figure 2, la carrure 9 présente une surface intérieure 9a parfaitement cylindrique ou prismatique, un réhaut 10, formant également le cran de glace, et formé entièrement en matière synthétique de dureté suffisante, par exemple 90 shore. Grâce à l'adhérence de la matière synthétique, on voit qu'il est également possible de supprimer tout moyen d'ancrage axial.According to a second embodiment shown in Figure 2, the middle 9 has an
Selon une troisième forme d'exécution représentée à la figure 3, la carrure 11 est venue d'une pièce, brute, avec un réhaut 12. Ce réhaut 12 présente toutefois un certain nombre, par exemple 4,6 ou 8, perçages ou cheminées 13 à sa naissance. Lors du surmoulage par la matière synthétique 14, cette matière remplit les cheminées et relie ainsi la matière synthétique se trouvant au-dessus et au-dessous du réhaut 12 en assurant une retenue supplémentaire.According to a third embodiment represented in FIG. 3, the middle part 11 came from a single piece, rough, with a
La figure 4 représente une variante d'exécution de la figure 2. Selon cette variante, on a fixé, lors du surmoulage, un réhaut métallique 15, rond ou de forme, sur la matière synthétique. La surface du réhaut 15 destinée au surmoulage est préparée comme celle de la carrure 9.FIG. 4 shows an alternative embodiment of FIG. 2. According to this alternative, a
Lorsque le réhaut est recouvert de matière synthétique selon la figure 1 ou constitué par la matière synthétique elle-même selon la figure 2, on peut métalliser ce réhaut.When the flange is covered with synthetic material according to Figure 1 or consisting of synthetic material tick itself according to Figure 2, we can metallize this flange.
Le procédé selon l'invention peut être appliqué à tous métaux, ferreux ou non ferreux, ainsi qu'à leurs alliages, tels que, par exemple, acier, acier inoxydable, laiton, carbures, borures, nitrures, maillechort, titane.The process according to the invention can be applied to all metals, ferrous or non-ferrous, as well as to their alloys, such as, for example, steel, stainless steel, brass, carbides, borides, nitrides, nickel silver, titanium.
