Description

La présente invention concerne un procédé d'assemblage d'un bracelet métallique comprenant deux rangées d'éléments extérieurs assemblés deux à deux par des goupilles formant des maillons rigides et au moins une rangée d'éléments intermédiaires situés entre les éléments extérieurs et montés sur les goupilles pour assurer la liaison entre deux maillons successifs ainsi qu'un bracelet fabriqué par la mise en oeuvre du procédé.The present invention relates to a method of assembling a metal bracelet comprising two rows of external elements assembled in pairs by pins forming rigid links and at least one row of intermediate elements located between the outer elements and mounted on them. pins to ensure the connection between two successive links and a bracelet manufactured by the implementation of the method.

Habituellement dans les bracelets métalliques comprenant au moins trois rangées d'éléments les goupilles qui les relient transversalement sont chassées à force dans des alésages de deux rangées extérieures ou collées ou fixées par brasure ou laser etc. Un tel assemblage n'est pas toujours satisfaisant esthétiquement et une ou plusieurs goupilles peuvent se désolidariser des éléments correspondants. Toutes les goupilles peuvent aussi être remplacées par des vis vissées dans un taraudage d'un des éléments ou en utilisant une vis et une goupille partiellement creuse avec un taraudage. Cet assemblage est coûteux.Usually in the metal bracelets comprising at least three rows of elements the pins that connect them transversely are forced out in bores of two outer rows or glued or fixed by brazing or laser etc. Such an assembly is not always aesthetically satisfactory and one or more pins can separate from the corresponding elements. All pins can also be replaced with screws screwed into one of the tapped holes or using a partially hollow screw and pin with tapping. This assembly is expensive.

EP 0968 670 décrit l'utilisation des goupilles à ressort dont une extrémité est munie d'un ergot radial collaborant avec un cylindre de blocage dans un assemblage du type à baïonnette. EP 0968 670 discloses the use of spring pins, one end of which is provided with a radial lug collaborating with a locking cylinder in a bayonet type assembly.

La présente invention a pour but de proposer un procédé d'assemblage palliant les inconvénients précités.The object of the present invention is to propose a method of assembly that overcomes the aforementioned drawbacks.

Le procédé selon l'invention est caractérisé en ce que la fixation des goupilles sur les maillons extérieurs se fait selon les étapes suivantes:

  • on réalise sur la face latérale intérieure de chaque élément extérieur deux alésages borgnes décalés axialement à fond plat d'un diamètre supérieure au diamètre des goupilles,
  • on choisit des goupilles lisses et on les introduit dans lesdits alésages, après avoir préalablement monté sur lesdites goupilles les éléments intermédiaires munis de deux alésages traversant,
  • on soude les goupilles et les éléments extérieurs par transparence en effectuant un bombardement par faisceau d'électrons sur la paroi supérieure ou inférieure des éléments extérieurs,
  • on effectue une opération de terminaison sur la surface bombardée pour enlever le cordon de soudure.
The method according to the invention is characterized in that the fixing of the pins on the outer links is done according to the following steps:
  • two axially offset, axially flat-bottomed blind bores having a diameter greater than the diameter of the pins are made on the inner lateral face of each outer element,
  • smooth pins are selected and introduced into said bores, having previously mounted on said pins the intermediate elements provided with two through bores,
  • the pins and external elements are welded by transparency by electron beam bombardment on the upper or lower wall of the outer elements,
  • a termination operation is performed on the bombarded surface to remove the weld bead.

Le soudage par transparence à travers une paroi métallique par bombardement d'un faisceau d'électrons est connu. Néanmoins, lorsqu'on l'applique dans le cas particulier d'un alésage borgne certains problèmes se posent. En effet, l'air emprisonné dans l'alésage, après y avoir chassé la goupille, se chauffe et a tendance à partir à travers la masse métallique en fusion sous l'effet du bombardement par le faisceau d'électrons. Il crée ainsi dans la masse métallique de bulles d'air qui nuisent à la qualité de la soudure si elles restent à l'intérieur ou elles déforment le cordon de soudure sur la surface en créant des trous et l'usinage est laborieux.Transparency welding through a metal wall by bombarding an electron beam is known. Nevertheless, when applied in the particular case of a blind bore some problems arise. In fact, the air trapped in the bore, after having driven out the pin, heats and tends to leave through the molten metal mass under the effect of the bombardment by the electron beam. He created thus in the metallic mass of air bubbles that affect the quality of the weld if they stay inside or they deform the weld bead on the surface by creating holes and machining is laborious.

Le procédé selon l'invention permet d'éliminer ces problèmes. En effet, le fond plat de l'alésage borgne permet, contrairement aux alésages habituels de forme conique, d'éliminer ou de réduire fortement la poche d'air qui subsisterait au fond de l'alésage. Le diamètre de l'alésage supérieur au diamètre de la goupille lisse permet lors de la mise en place de la goupille l'évacuation de l'air et accessoirement lors du soudage l'air restant et chauffé peut aussi quitter l'alésage sans passer dans la masse en fusion. On obtient ainsi sur la surface bombardée de l'élément un cordon de soudure formant une surépaisseur de matière réduite que l'on peut facilement enlever par une opération de terminaison. La faible surépaisseur contribue à ce que la perte de matière soit faible. La régularité du cordon de soudure et sa faible épaisseur permettent par une simple opération de terminaison de supprimer toute trace visible du soudage.The method according to the invention makes it possible to eliminate these problems. Indeed, the flat bottom of the blind bore makes it possible, unlike the usual conical bores, to eliminate or greatly reduce the air pocket that would remain at the bottom of the bore. The diameter of the bore greater than the diameter of the pin allows during the installation of the pin the evacuation of the air and incidentally during welding the remaining air and heated can also leave the bore without passing through the molten mass. Thus, on the bombarded surface of the element, a weld bead forming a reduced thickness of material is obtained which can be easily removed by a termination operation. The low thickness contributes to a low material loss. The regularity of the weld bead and its small thickness allow by a simple termination operation to remove any visible traces of welding.

Selon une variante préférée après l'alésage lesdits éléments sont soumis à une opération de tonnelage pour enlever les bavures suivie d'une opération de nettoyage pour éliminer toute trace de poudre.According to a preferred variant after the boring said elements are subjected to a tumbling operation to remove burrs followed by a cleaning operation to remove any trace of powder.

En effet, après la formation des alésages traversant pour les éléments intermédiaires et borgnes pour les éléments extérieurs, on élimine les bavures par tonnelage. Étant donné que des poudres métalliques se déposent sur les éléments on effectue un nettoyage pour les éliminer. Le nettoyage consiste à un lavage dans un liquide car il est important d'éliminer les poudres métalliques formées lors du tonnelage parce qu'elles ont une influence négative sur la soudure par transparence.Indeed, after the formation of the through bores for the intermediate and blind elements for the outer elements, the burrs are eliminated by tumbling. Since metal powders are deposited on the elements, cleaning is carried out to eliminate them. The cleaning consists of washing in a liquid because it is important to eliminate the metal powders formed during the tumbling because they have a negative influence on the weld by transparency.

Selon une autre variante d'exécution les éléments intermédiaires sont aussi soudés par transparence sur les goupilles.According to another embodiment of the intermediate elements are also welded by transparency on the pins.

Si l'on soude uniquement les éléments extérieurs sur les goupilles on obtient un bracelet articulé, en soudant aussi les éléments intermédiaires sur les goupilles on obtient un bracelet rigide.If we only weld the outer elements on the pins we get an articulated bracelet, also soldering the intermediate elements on the pins we get a rigid bracelet.

L'invention concerne aussi un bracelet fabriqué par la mise en oeuvre du procédé, caractérisé par le fait que ledit bracelet est un bracelet de montre et pour quelques maillons les alésages sont traversant et les goupilles sont remplacées par des vis pour permettre la mise en longueur du bracelet.The invention also relates to a bracelet manufactured by the implementation of the method, characterized in that said bracelet is a watch strap and for some links the bores are through and the pins are replaced by screws to allow the setting in length of the bracelet.

En effet, pour permettre la mise en longueur du bracelet pour l'adapter au tour de poignée de l'utilisateur il faut prévoir comme d'habitude quelques maillons dans lesquels les goupilles sont remplacées par des vis.Indeed, to allow the lengthening of the bracelet to adapt to the handle turn of the user must provide as usual some links in which the pins are replaced by screws.

Selon une variante le métal utilisé pour les éléments et les goupilles est soit de l'acier soit de l'or soit du titane.According to one variant, the metal used for the elements and the pins is either steel or gold or titanium.

L'invention sera décrite plus en détails à l'aide du dessin annexé.The invention will be described in more detail with the aid of the accompanying drawing.

La figure 1 est une vue partielle d'un bracelet avec trois rangées d'éléments.The figure 1 is a partial view of a bracelet with three rows of elements.

La figure 2 montre un élément extérieur avec une goupille après le soudage.The figure 2 shows an outer element with a pin after welding.

La figure 3 est une vue en coupe selon l'axe longitudinal de la goupille de la figure 2.The figure 3 is a sectional view along the longitudinal axis of the pin of the figure 2 .

A la figure 1 une partie d'un bracelet articulé 1 est représentée. Il se compose de trois rangées d'éléments dont deux extérieures et une intérieure. Le nombre des rangées intérieures peut être supérieur à un. Les éléments 2 et 3 des rangées extérieures sont reliés transversalement par des goupilles 5 qui sont fixées par soudage dans deux alésages borgnes dont sont munis les éléments extérieurs 2 et 3. Les éléments intérieurs 4 sont munis de deux alésages traversant et sont articulés sur les goupilles 5 (schématiquement représentées sur la figure 1 par leurs axes) libres en rotation et en décalage par rapport aux éléments extérieurs 2 et 3.To the figure 1 part of an articulated bracelet 1 is shown. It consists of three rows of elements, two of which are exterior and one interior. The number of inner rows may be greater than one. The elements 2 and 3 of the outer rows are connected transversely by pins 5 which are fixed by welding in two blind bores which are provided with the outer elements 2 and 3. The inner elements 4 are provided with two through bores and are articulated on the pins 5 (schematically represented on the figure 1 by their axes) free in rotation and offset from the outer elements 2 and 3.

A l'aide des figures 2 et 3 le soudage d'une goupille 5 sur un élément 2 sera décrit.With the help of Figures 2 and 3 the welding of a pin 5 on an element 2 will be described.

Chaque élément extérieur 2 (ou 3) est muni sur sa face latérale intérieure 20 de deux alésages borgnes 21 à fond plat. Le diamètre de l'alésage est légèrement supérieur au diamètre de l'extrémité d'une goupille 5. Cette différence est de l'ordre de 0.03 mm. Chaque goupille lisse présente deux épaulements 51. Le diamètre de la goupille 5 entre les deux épaulements est supérieur au diamètre des alésages 21 afin d'assurer un écartement fixe entre les éléments 2 et 3, car la profondeur des alésages 21 peut éventuellement varier. En introduisant les goupilles 5 dans les alésages 21 jusqu'à ce que les épaulements 51 s'appuient contre les faces 20 un écartement identique entre les éléments 2 et 3 est assuré. Lors de l'introduction des extrémités 52 des goupilles 5, de diamètre inférieur au diamètre des alésages 21, l'air contenu dans les alésages 21 est chassé vers l'extérieur grâce à cette différence des diamètres. Le fond plat des alésages permet aussi de limiter l'air qui peut subsister au fond de l'alésage, par rapport à un fond conique, si l'extrémité de la goupille ne vient pas en contact avec le fond.Each outer member 2 (or 3) is provided on its inner side face 20 with two blind holes 21 flat bottom. The diameter of the bore is slightly greater than the diameter of the end of a pin 5. This difference is of the order of 0.03 mm. Each smooth pin has two shoulders 51. The diameter of the pin 5 between the two shoulders is greater than the diameter of the bores 21 to ensure a fixed spacing between the elements 2 and 3, because the depth of the bores 21 may vary. By introducing the pins 5 into the bores 21 until the shoulders 51 bear against the faces 20 an identical spacing between the elements 2 and 3 is ensured. When the ends 52 of the pins 5, whose diameter is smaller than the diameter of the bores 21, are introduced, the air contained in the bores 21 is driven outwards thanks to this difference in diameters. The flat bottom of the bores also limits the air that can remain at the bottom of the bore, compared to a conical bottom, if the end of the pin does not come into contact with the bottom.

Après avoir introduit les goupilles 5 dans les alésages un bombardement par faisceau d'électrons est appliqué sur la face supérieure 22 (ou inférieure) des éléments 2 et 3 permettant de souder par transparence les extrémités des goupilles 5 dans les alésages 21. Sur les figures 2 et 3 on voit la partie fondue 7 de l'élément 2 et de la goupille 5 sous l'effet du soudage par transparence ainsi que la surépaisseur 6 subsistant à la fin. Cette surépaisseur 6 ou cordon de soudure peut être enlevé par une opération de terminaison, la surépaisseur étant comprise entre 0.05 et 0.15 mm. Pendant le soudage par transparence l'air qui se trouve dans l'alésage et qui se dilate par la chaleur dégagée s'évacue aussi vers l'extérieur sans avoir tendance de passer à travers la masse fondue.After having introduced the pins 5 into the bores, an electron beam bombardment is applied to the upper face 22 (or lower) of the elements 2 and 3 for welding the ends of the pins 5 in the bores 21 transparently. Figures 2 and 3 the molten portion 7 of the element 2 and the pin 5 are seen under the effect of the transparency welding and the excess thickness 6 remaining at the end. This excess thickness 6 or weld bead can be removed by a termination operation, the excess thickness being between 0.05 and 0.15 mm. During the transparency welding, the air in the bore which expands with the heat released also discharges outwardly without any tendency to pass through the melt.

Avant de procéder au soudage par transparence, les différents éléments du bracelet 1 sont assemblés, comme représenté à la figure 1 et ensuite au procède au bombardement par faisceaux d'électrons sur les éléments 2 et 3.Before proceeding with the welding by transparency, the various elements of the bracelet 1 are assembled, as shown in FIG. figure 1 and then electron beam bombardment on elements 2 and 3.

Pour permettre l'adaptation du bracelet, notamment pour les bracelets de montre, on ajoute aux extrémités du bracelet quelques éléments ayant la même disposition mais avec des alésages traversants et au lieu des goupilles on utilise des vis.To allow the adaptation of the bracelet, especially for the watch straps, is added to the ends of the bracelet a few elements having the same provision but with through holes and instead of the pins are used screws.

Après avoir formé les alésages sur les éléments 2, 3, et 4 il est souhaitable d'éliminer les bavures. Dans ce but on fait subir aux éléments une opération de tonnelage. Les éléments sont introduits dans un récipient contenant des éléments en acier tels que billes ou éléments similaires et soumis à une série de vibrations. Les bavures sont éliminées par le frottement des éléments en acier avec les éléments du bracelet. Ce frottement éliminant les bavures crée des poudres de métal que l'on élimine par lavage.After forming the bores on the elements 2, 3, and 4 it is desirable to eliminate the burrs. For this purpose the elements are subjected to a tumbling operation. The elements are introduced into a container containing steel elements such as balls or similar elements and subjected to a series of vibrations. The burrs are eliminated by the friction of the steel elements with the elements of the bracelet. This friction eliminates burrs creates metal powders that are removed by washing.

Le métal utilisé pour les éléments 2, 3 et les goupilles est soit de l'or soit de l'acier soit du titane, étant entendu que le même métal est utilisé pour les éléments et les goupilles.The metal used for the elements 2, 3 and the pins is either gold or steel or titanium, it being understood that the same metal is used for the elements and the pins.

Après le soudage une opération de lavage du bracelet peut aussi être nécessaire pour éliminer les traces (noircissures) de vapeur de métal produite lors de l'opération de soudage.After welding a wristwashing operation may also be necessary to remove traces (blackouts) of metal vapor produced during the welding operation.

Si l'on souhaite obtenir un bracelet rigide on procède aussi à un soudage par transparence sur les éléments intermédiaires pour le rendre solidaires des goupilles.If it is desired to obtain a rigid bracelet is also carried out a transparency welding on the intermediate elements to make it integral with the pins.
