Description
Procédé de fabrication en série de pièces de boîtes de montres. La présente invention a pour objet tin pro cédé (le fabrication en série de pièces de boîtes de montres, notamment de carrures ou lunet tes. Ce procédé est caractérisé par le fait. qu'on utilise un tube profilé dont la section corres pond à la section droite de ces pièces, et par le fait qu'on pratique dans le tube, avant son tronçonnage, au moins une partie des perçages desdites pièces.
<B>Le</B> dessin annexé illustre un exemple de mise en #uvre de l'objet de l'invention et un produit obtenu par le procédé décrit, ci-dessous à titre d'exemple.
La fig. 1 est une vue en perspective du tube profilé et la fig. ? est une vue en perspective d'une carrure pour boîte de montre.
Le tube représenté, obtenu par laminage, est désigné par 1; sa section droite correspond à la section de la carrure que l'on veut obtenir. Il comprend un corps la muni de quatre ner- N tires lb devant constituer, après le tronçon nage, des cornes pour la. fixation d'un bracelet. On pratique dans le corps 1a, avant de tron- conner, une série de trous ? servant an pas sage des tiges de remontoir des mouvements; de même, on pratique, dans chacune des ner vures lb, une série de trous 3 destinés à, rece voir les barrettes de fixation des bracelets.
Une fois ces perçages effectués, on procède au polissage du tube. C'est seulement après que ces opérations ont, été effectuées que l'une des extrémités est. travaillée et ensuite tron çonnée sur une décolleteuse. Après chaque tronçonnage, l'extrémité libre est à son tour travaillée, de sorte qu'une fois le tube entière ment tronçonné, les pièces séparées sont polies et percées et ont. une de leurs faces travaillée. Il suffit alors de les terminer par le travail de leur seconde face pour obtenir des car rures telles que la carrure 4 représentée dans la flet \?.
A method of mass production of parts for watch cases. The object of the present invention is a process (the mass production of parts for watch cases, in particular middle or bezel. This process is characterized in that a profiled tube is used, the section of which corresponds to the cross section of these parts, and by the fact that in the tube, before cutting it, at least part of the bores of said parts.
<B> The </B> accompanying drawing illustrates an example of implementation of the object of the invention and a product obtained by the process described below by way of example.
Fig. 1 is a perspective view of the profiled tube and FIG. ? is a perspective view of a middle part for a watch case.
The tube shown, obtained by rolling, is designated by 1; its straight section corresponds to the section of the middle part that we want to obtain. It comprises a body provided with four nerves lb to constitute, after the swimming section, horns for the. attaching a bracelet. Do we practice in the body 1a, before cutting, a series of holes? serving as a step for winding stems for movements; Likewise, in each of the nerves lb, a series of holes 3 intended to receive the straps for fixing the bracelets is practiced.
Once these holes have been made, the tube is polished. It is only after these operations have been carried out that one of the ends is. worked and then cut on a bar turning machine. After each cutting, the free end is in turn worked, so that after the tube has been completely cut off, the separate parts are polished and drilled and have. one of their faces worked. It is then sufficient to finish them by working on their second side to obtain edges such as the caseband 4 shown in the flet \ ?.
