Description
Procédé de fabrication d'une boîte de montre et boîte de montre obtenue par ce procédé. La présente invention se rapporte à un procédé de fabrication, d'une boite de montre. Ce procédé est ,caractérisé en ce qu'on sort par emboutissage d'une feuille métallique une ébauche du corps de la boîte,
et en ce qu'on découpe la matière adjacente à la partie em- boutie,de façon: à ménager des languettes que l'on replie sur elles-mêmes pour en former les cornes des -anises.
Le dessin ci-annexé représente, à titre d'exemple et à trois états successifs, l'ébauche ,du corps d'une forme d'exécution de la boîte de montre,olbtenue au moyen du procédé selon l'invention.
Les fig. 1, 3, 5 sont des vues en plan et les fig. 2, 4, 6 des coupes verticales.
D'une feuille de métal 7 on sort, par em- boutiesage, l'ébauche de la carrure-lunette 8 d'une boîte de montre ronde. On peut, dans une même opération ou séparément, avant ou après l'emboutissage, ménager l'ouverture 9 pour la glace.
La phase suivante du procédé de fabrica tion consiste à découper la matière adjacente à -la partie emboutie 8 de façon à ménager des languettes 10 (fig. 3) qu'il suffit ensuite de replier sur elles-mêmes (fig. 5 et 6), vers le haut ou vers le bas, pour en former les cornes 11 dies anses.
Le pliage peut aussi se faire longitudi- nalement et l'on peut donner aux cornes la forme que l'on désire.
Il va sans dire que ce procédé s'applique aussi bien aux boîtes de forme qu'aux boîtes rondes,.
La carrure emboutie peut au besoin servir d'armature à un :revêtement de matière plastique ou,de métal noble. Le procédé per met d'obtenir très économiquement une boîte de montre légère et en, grande série.
A method of manufacturing a watch case and watch case obtained by this method. The present invention relates to a method of manufacturing a watch case. This process is characterized in that a blank of the body of the box is taken out by stamping from a metal sheet,
and in that the material adjacent to the embossed part is cut, so as to: provide tongues which are folded back on themselves to form the horns of the anise.
The accompanying drawing represents, by way of example and in three successive states, the blank of the body of an embodiment of the watch case, obtained by means of the method according to the invention.
Figs. 1, 3, 5 are plan views and FIGS. 2, 4, 6 vertical sections.
From a sheet of metal 7, the blank for the caseband 8 of a round watch case is taken out by stamping. It is possible, in the same operation or separately, before or after stamping, to provide the opening 9 for the ice.
The next phase of the manufacturing process consists in cutting the material adjacent to the stamped part 8 so as to provide tabs 10 (fig. 3) which then need only be folded back on themselves (fig. 5 and 6). , upwards or downwards, to form the horns 11 dies handles.
Folding can also be done longitudinally and the horns can be given the shape you want.
It goes without saying that this process is applicable to shaped boxes as well as round boxes.
The stamped middle part can serve as a reinforcement for a: coating of plastic material or of noble metal. The process makes it possible to obtain very economically a light watch case in large series.
