Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention se rapporte à un assortiment horloger pour une pièce d'horlogerie utilisant un alliage métallique amorphe et notamment un tel assortiment comportant une pièce horlogère dont le matériau ne comporte pas de domaine plastique utilisable, c'est-à-dire avec un domaine plastique très restreint.The invention relates to a watchmaking assortment for a timepiece using an amorphous metal alloy and in particular such an assortment comprising a watchmaking part whose material does not comprise a usable plastic domain, that is to say with a field very limited plastic.

Un tel matériau peut être de manière nullement limitative du silicium monocristallin dopé ou non, du silicium polycristallin dopé ou non, de l'oxyde de silicium, du quartz, de la silice, du corindon monocristallin, du corindon polycristallin, de l'alumine, du rubis, du nitrure de silicium ou du carbure de silicium. Ce matériau pouvant comporter au moins un revêtement partiel d'oxyde de silicium, de nitrure de silicium, de carbure de silicium ou d'un allotrope du carbone. Bien entendu, d'autres types de matériau tels que d'autres céramiques peuvent envisagés tout comme d'autres types de revêtement.Such a material may be in no way limiting doped or un doped monocrystalline silicon, polycrystalline silicon doped or not, silicon oxide, quartz, silica, monocrystalline corundum, polycrystalline corundum, alumina, ruby, silicon nitride or silicon carbide. This material may comprise at least one partial coating of silicon oxide, silicon nitride, silicon carbide or a carbon allotrope. Of course, other types of material such as other ceramics may be considered as other types of coating.

Selon un premier mode de réalisation de l'invention illustré notamment aux figures 8 et 9, l'assortiment horloger 1, 11, 21 comporte une pièce horlogère 3, 13 fixée à un axe 5 à l'aide d'un élément de fixation 7, 17. Avantageusement selon l'invention, l'élément de fixation 7, 17 est en alliage métallique au moins partiellement amorphe et est solidaire de la pièce horlogère 3, 13 par enfoncement partiel comme visible aux figure 8 et 9. De plus, avantageusement selon l'invention, l'élément de fixation 7, 17 comporte un trou 8, 18 dans lequel est chassé l'axe 5.According to a first embodiment of the invention, illustrated in particular in figures 8 and 9 , the watchmaking assortment 1, 11, 21 comprises a watch part 3, 13 fixed to an axis 5 by means of a fixing element 7, 17. Advantageously according to the invention, the fastening element 7, 17 is at least partially amorphous metal alloy and is integral with the watch part 3, 13 by partial depression as visible at figure 8 and 9 . In addition, advantageously according to the invention, the fixing element 7, 17 comprises a hole 8, 18 in which the shaft 5 is driven.

On comprend avantageusement selon l'invention, qu'uniquement par recouvrement partiel de la pièce horlogère 3, 13 par l'élément de fixation 7, 17, il n'est plus nécessaire de mettre en oeuvre un collage. En effet, sous certaines conditions expliquées ci-dessous, un alliage métallique au moins partiellement amorphe autorise de manière avantageuse à prendre la forme de n'importe quel objet à la manière d'une pâte déformée. Cette malléabilité de l'élément de fixation 7 conjuguée à la rugosité de surface de la pièce horlogère 3, 13 offre une adhérence suffisante pour une application horlogère.It is advantageously understood according to the invention, only by partial recovery of the watch part 3, 13 by the fastener 7, 17, it is no longer necessary to implement a bonding. Indeed, under certain conditions explained below, an at least partially amorphous metal alloy advantageously allows to take the form of any object in the manner of a deformed dough. This malleability of the fixing element 7 combined with the surface roughness of the watch part 3, 13 provides sufficient adhesion for a watch application.

Avantageusement selon l'invention, selon une première alternative du premier mode de réalisation, l'assortiment 1 comporte un élément de fixation 7 qui est monté contre une portée 6 de l'axe 5 comme illustré à la figure 8. Cette première alternative évite que la pièce horlogère 3 touche l'axe 5. En effet, préférentiellement selon l'invention, la pièce horlogère 3 comporte, comme l'élément de fixation 7, un ajourage 4 de plus grande section que le trou 8.Advantageously according to the invention, according to a first alternative of the first embodiment, the set 1 comprises a fixing element 7 which is mounted against a bearing surface 6 of the axis 5 as illustrated in FIG. figure 8 . This first alternative avoids that the watch part 3 touches the axis 5. In fact, preferably according to the invention, the watch part 3 comprises, like the fastening element 7, an openwork 4 of larger section than the hole 8.

Selon une deuxième alternative du premier mode de réalisation, l'assortiment 11 comporte au contraire une pièce horlogère 3 qui est montée contre une portée 6 de l'axe 5 comme illustré à la figure 9. Cette deuxième alternative garantit une perpendicularité optimale de la pièce horlogère 3 par rapport à l'axe 5. En effet, préférentiellement selon l'invention, la pièce horlogère 3 étant plaquée entre la portée 6 et l'élément de fixation 7, son positionnement comporte moins de degrés de liberté.According to a second alternative of the first embodiment, the set 11 comprises on the contrary a watch piece 3 which is mounted against a bearing surface 6 of the axis 5 as illustrated in FIG. figure 9 . This second alternative guarantees an optimal perpendicularity of the watch part 3 with respect to the axis 5. In fact, preferentially according to the invention, the watch part 3 being pressed between the bearing surface 6 and the fastening element 7, its positioning comprises less degrees of freedom.

De manière préférée selon l'invention, il a été trouvé qu'au moins un cinquième de la hauteur de la pièce horlogère 3, 13 recouvert par l'élément de fixation 7, 17 permet une bonne solidarisation lorsque la hauteur de la pièce horlogère 3, 13 est comprise entre 100 et 500 µm. De plus, il a également été trouvé préférentiellement qu'une épaisseur minimale de 50 µm de l'élément de fixation 7, 17 au niveau du trou 8, 18 ne recouvrant pas la pièce horlogère 3, 13 permet un bon chassage.In a preferred manner according to the invention, it has been found that at least one fifth of the height of the watch part 3, 13 covered by the fixing element 7, 17 allows a good fastening when the height of the watch part 3 , 13 is between 100 and 500 μm. In addition, it has also been found preferentially that a minimum thickness of 50 microns of the fixing element 7, 17 at the hole 8, 18 not covering the timepiece 3, 13 allows a good hunting.

Préférentiellement selon l'invention, l'élément de fixation 7, 17 est un alliage à base magnésium, à base titane, à base zirconium, à base fer, à base cobalt, à base or, à base palladium ou à base platine. Plus précisément, un élément de fixation 7, 17 formé par un alliage à structure au moins partiellement amorphe du type ZrTiCuNiBe, PdCuNiP ou PtCuNiP ont chacun donné satisfaction.Preferably, according to the invention, the fixing element 7, 17 is a magnesium base, titanium-based, zirconium-based, iron-based, cobalt-based, gold-based, palladium-based or platinum-based alloy. More specifically, a fixing element 7, 17 formed by an alloy with at least partially amorphous structure of the ZrTiCuNiBe, PdCuNiP or PtCuNiP type have each been satisfactory.

Selon une variante du premier mode de réalisation visible à la figure 12, l'assortiment 21 comporte une pièce horlogère 13 formée avec au moins un évidement 12 permettant d'augmenter la surface de contact avec l'élément de fixation 17. Chaque évidement 12 peut être borgne ou traversant et peut être positionné indifféremment en vis-à-vis de l'élément de fixation 17.According to a variant of the first embodiment visible at figure 12 , the set 21 comprises a watchmaking part 13 formed with at least one recess 12 making it possible to increase the area of contact with the fastening element 17. Each recess 12 can be blind or through and can be positioned indifferently with respect to of the fastening element 17.

Dans l'exemple illustré à la figure 12, l'élément de fixation 17 est monté contre une portée 6 de l'axe 5. Toutefois, bien entendu, cette variante avec une pièce horlogère 13 formée avec au moins un évidement 12 peut également être assemblée selon la deuxième alternative de la figure 9 citée ci-dessus, c'est-à-dire avec la pièce horlogère 13 qui est montée contre la portée 6 de l'axe 5.In the example shown in figure 12 , the fastening element 17 is mounted against a bearing surface 6 of the axis 5. However, of course, this variant with a watch part 13 formed with at least one recess 12 can also be assembled according to the second alternative of the figure 9 quoted above, that is to say with the watch part 13 which is mounted against the scope 6 of the axis 5.

On comprend immédiatement que l'assortiment horloger 1, 11, 21 peut ainsi former tout ou partie d'un rouage 101, d'un système d'échappement 103 ou d'un résonateur 105. Plus précisément, la pièce horlogère 3, 13 peut ainsi former une roue 102, un pignon 104, 112, une masse oscillante 106, un ressort (tel par exemple qu'un ressort de barillet), une roue d'échappement 107, une baguette 108 d'ancre 109, un dard 110 d'ancre 109, une fourchette 111 d'ancre 109, un balancier 113, un plateau (tel par exemple qu'un double plateau tenant une cheville) ou un spiral 115.It is immediately understood that the watchmaking assortment 1, 11, 21 can thus form all or part of a gear train 101, an exhaust system 103 or a resonator 105. More precisely, the watch part 3, 13 can thus forming a wheel 102, a pinion 104, 112, an oscillating mass 106, a spring (such as for example a mainspring), an escape wheel 107, an anchor rod 108, a dart 110 anchor 109, an anchor fork 111 109, a rocker 113, a plate (such as for example a double plate holding an ankle) or a spiral 115.

Selon un deuxième mode de réalisation de l'invention illustré notamment aux figures 14 et 15, l'assortiment horloger 31, 41, 51 comporte une pièce horlogère 33, 43 fixée à un axe 35 à l'aide d'un élément de fixation 37, 47 et d'un organe de chassage 39, 49. Avantageusement selon l'invention, l'élément de fixation 37, 47 est en alliage métallique au moins partiellement amorphe, est solidaire de la pièce horlogère 33, 43 et de l'organe de chassage 39, 49 par enfoncement partiel respectif comme visible aux figure 14 et 15. De plus, avantageusement selon l'invention, l'organe de chassage 39, 49 comporte un trou 38, 48 dans lequel est chassé l'axe 35.According to a second embodiment of the invention illustrated in particular in Figures 14 and 15 , the watchmaking assortment 31, 41, 51 comprises a watch part 33, 43 fixed to an axis 35 by means of a fastening element 37, 47 and a driving member 39, 49. Advantageously according to the invention, the fastening element 37, 47 is at least partially amorphous metal alloy is integral with the watch part 33, 43 and the driving member 39, 49 by partial depression respectively as visible to figure 14 and 15 . In addition, advantageously according to the invention, the driving member 39, 49 comprises a hole 38, 48 in which the shaft 35 is driven.

On comprend avantageusement selon l'invention, qu'uniquement par recouvrement partiel de la pièce horlogère 33, 43 et de l'organe de chassage 39, 49 par l'élément de fixation 37, 47, il n'est plus nécessaire de mettre en oeuvre un collage. En effet, sous certaines conditions expliquées ci-dessous, un alliage métallique au moins partiellement amorphe autorise de manière avantageuse à prendre la forme de n'importe quel objet à la manière d'une pâte déformée. Cette malléabilité de l'élément de fixation 37, 47 conjuguée à la rugosité de surface de la pièce horlogère 33, 43 et de l'organe de chassage 39, 49 offre une adhérence suffisante pour une application horlogère.It is advantageously understood according to the invention, that only by partially covering the watch part 33, 43 and the driving member 39, 49 by the fixing element 37, 47, it is no longer necessary to work a collage. Indeed, under certain conditions explained below, an at least partially amorphous metal alloy advantageously allows to take the form of any object in the manner of a deformed dough. This malleability of the fixing element 37, 47 combined with the surface roughness of the watch part 33, 43 and the driving member 39, 49 provides sufficient adhesion for a watch application.

Avantageusement selon l'invention, selon une première alternative du deuxième mode de réalisation, l'assortiment 31 comporte un organe de chassage 39 qui est monté contre une portée 36 de l'axe 35 comme illustré à la figure 14. Cette première alternative évite que la pièce horlogère 33 touche l'axe 35. En effet, préférentiellement selon l'invention, la pièce horlogère 33 comporte, comme l'organe de chassage 39, un ajourage 34, mais de plus grande section que le trou 38.Advantageously according to the invention, according to a first alternative of the second embodiment, the set 31 comprises a driving member 39 which is mounted against a bearing surface 36 of the shaft 35 as illustrated in FIG. figure 14 . This first alternative prevents the watch part 33 from touching the axis 35. In fact, preferably according to the invention, the watchmaking piece 33 comprises, like the driving member 39, an opening 34, but of larger section than the hole 38.

Selon une deuxième alternative du deuxième mode de réalisation, l'assortiment 41 comporte au contraire une pièce horlogère 33 qui est montée contre une portée 36 de l'axe 35 comme illustré à la figure 15. Cette deuxième alternative garantie une verticalité optimale de la pièce horlogère 33 par rapport à l'axe 35. En effet, préférentiellement selon l'invention, la pièce horlogère 33 étant plaquée entre la portée 36 et l'organe de chassage 39, son positionnement comporte moins de degrés de liberté.According to a second alternative of the second embodiment, the set 41 comprises on the contrary a watch piece 33 which is mounted against a bearing 36 of the axis 35 as illustrated in FIG. figure 15 . This second alternative guarantees an optimal verticality of the watch part 33 with respect to the axis 35. In fact, preferentially according to the invention, the timepiece 33 being pressed between the bearing surface 36 and the driving member 39, its positioning comprises less degrees of freedom.

De manière préférée selon l'invention, il a été trouvé qu'au moins un cinquième de la hauteur de la pièce horlogère 33, 43 et de la hauteur de l'organe de chassage 39, 49 recouvert par l'élément de fixation 37, 47 permet une bonne solidarisation lorsque la hauteur de la pièce horlogère 33, 43 et/ou la hauteur de l'organe de chassage 39, 49 sont chacune comprise entre 100 et 500 µm.In a preferred manner according to the invention, it has been found that at least one fifth of the height of the watch part 33, 43 and the height of the driving member 39, 49 covered by the fixing element 37, 47 allows good fastening when the height of the watch part 33, 43 and / or the height of the driving member 39, 49 are each between 100 and 500 microns.

Préférentiellement selon l'invention, l'élément de fixation 37, 47 est un alliage à base magnésium, à base titane, à base zirconium, à base fer, à base cobalt, à base or, à base palladium ou à base platine. Plus précisément, un élément de fixation 37, 47 formé par un alliage à structure au moins partiellement amorphe du type ZrTiCuNiBe, PdCuNiP ou PtCuNiP ont chacun donné satisfaction.Preferably, according to the invention, the fixing element 37, 47 is a magnesium base, titanium-based, zirconium-based, iron-based, cobalt-based, gold-based, palladium-based or platinum-based alloy. More specifically, a fastening element 37, 47 formed by an alloy with at least partially amorphous structure of the ZrTiCuNiBe, PdCuNiP or PtCuNiP type have each been satisfactory.

De plus, l'organe de chassage 39, 49 est, de manière préférée, un métal ou un alliage métallique tel qu'un acier inoxydable, un laiton ou un maillechort.In addition, the driving member 39, 49 is preferably a metal or a metal alloy such as stainless steel, brass or nickel silver.

Selon une variante du deuxième mode de réalisation visible à la figure 16, l'assortiment 51 comporte une pièce horlogère 43 formée avec au moins un évidement 42 permettant d'augmenter la surface de contact avec l'élément de fixation 47. Il est également visible que l'organe de chassage 49 peut également comporter au moins un évidement 46. Les évidements 42, 46 peuvent être borgnes ou traversants et peuvent être positionnés indifféremment en vis-à-vis de l'élément de fixation 47.According to a variant of the second embodiment visible at the figure 16 the set 51 comprises a watchmaking part 43 formed with at least one recess 42 making it possible to increase the area of contact with the fastening element 47. It is also visible that the driving member 49 may also comprise at least one 46. The recesses 42, 46 may be blind or through and may be positioned indifferently in relation to the fastening element 47.

Dans l'exemple illustré à la figure 16, l'organe de chassage 49 est monté contre une portée 36 de l'axe 35. Toutefois, bien entendu, cette variante avec une pièce horlogère 43 formée avec au moins un évidement 42 et/ou un organe de chassage 49 formé avec au moins un évidement 46 peut également être assemblée selon la deuxième alternative de la figure 15 citée ci-dessus, c'est-à-dire avec la pièce horlogère 43 qui est montée contre la portée 36 de l'axe 35.In the example shown in figure 16 , the driving member 49 is mounted against a bearing 36 of the axis 35. However, of course, this variant with a watch part 43 formed with at least one recess 42 and / or a driving member 49 formed with at least one recess 46 can also be assembled according to the second alternative of the figure 15 quoted above, that is to say with the watch part 43 which is mounted against the bearing surface 36 of the axis 35.

On comprend immédiatement que l'assortiment horloger 31, 41, 51 peut ainsi former tout ou partie d'un rouage 101, d'un système d'échappement 103 ou d'un résonateur 105. Plus précisément, la pièce horlogère 33, 43 peut ainsi former une roue 102, un pignon 104, 112, une masse oscillante 106, un ressort (tel par exemple qu'un ressort de barillet), une roue d'échappement 107, une baguette 108 d'ancre 109, un dard 110 d'ancre 109, une fourchette 111 d'ancre 109, un balancier 113, un plateau (tel par exemple qu'un double plateau tenant une cheville) ou un spiral 115.It is immediately understood that the watchmaking assortment 31, 41, 51 can thus form all or part of a gear train 101, an exhaust system 103 or a resonator 105. More precisely, the watchmaking component 33, 43 can thus forming a wheel 102, a pinion 104, 112, an oscillating mass 106, a spring (such as for example a mainspring), an escape wheel 107, an anchor rod 108, a dart 110 d anchor 109, an anchor fork 111 109, a rocker 113, a plate (such as for example a double plate holding an ankle) or a spiral 115.

Des procédés d'assemblage selon l'invention d'un assortiment horloger vont maintenant être expliqués en relation avec les figures 1 à 16. Selon un premier mode de réalisation d'assortiment horloger 1, 11, 21, le procédé selon l'invention comporte une première étape a) destinée à fabriquer une pièce horlogère 3, 13, 23 et un élément de fixation 7', 27' en alliage métallique au moins partiellement amorphe muni d'un trou 8', 28'. Afin de mieux comprendre le procédé, un spiral 23 est utilisé comme une pièce horlogère dans l'exemple des figures 1 à 5. Bien entendu, la pièce horlogère 3, 13, 23 ne saurait se limiter à un spiral.Methods of assembly according to the invention of a watchmaking assortment will now be explained in relation to the Figures 1 to 16 . According to a first embodiment of watchmaking assortment 1, 11, 21, the method according to the invention comprises a first step a) intended to manufacture a watch part 3, 13, 23 and a fastening element 7 ', 27' in at least partially amorphous metal alloy provided with a hole 8 ', 28'. In order to better understand the process, a hairspring 23 is used as a watch piece in the example of Figures 1 to 5 . Of course, the timepiece 3, 13, 23 can not be limited to a spiral.

Comme illustré aux figures 1 et 2, la pièce horlogère 23 comporte une virole 22 comportant un ajourage 24 sensiblement triangulaire et une lame 20 enroulée sur elle-même. Un ajourage 4 et une pièce horlogère 3 similaires sont également schématisés à la figure 6.As illustrated in figures 1 and 2 , the watch 23 comprises a ferrule 22 having a substantially triangular opening 24 and a blade 20 wound on itself. A similar ajourage 4 and a watch piece 3 are also shown schematically in the figure 6 .

De plus, à la figure 3 est montré un élément de fixation 27' selon l'invention de forme sensiblement annulaire et comportant un trou 28' traversant. Cet élément de fixation 27' est une ébauche, c'est-à-dire une préforme destinée à être déformée lors de l'étape b) pour former l'élément de fixation 27 final. On comprend donc que sa forme n'a pas une importance primordiale tout comme la géométrie du trou 28' comme expliqué ci-dessous. Un trou 8' et un élément de fixation 7' similaires sont également schématisés à la figure 6.Moreover, figure 3 is shown a fastener 27 'according to the invention of substantially annular shape and having a hole 28' through. This fixing element 27 'is a blank, that is to say a preform intended to be deformed during step b) to form the final fastening element 27. So we understand that its shape does not have a primary importance as the geometry of the hole 28 'as explained below. A similar hole 8 'and fastener 7' are also shown schematically in FIG. figure 6 .

Toutefois, la présence d'un trou 8', 28' à ce stade n'est pas indispensable. En effet, alternativement un disque pourrait être utilisé à la place d'un élément de forme sensiblement annulaire. Le trou pourrait alors être formé lorsque le disque est déformé à chaud.However, the presence of a hole 8 ', 28' at this stage is not essential. Indeed, alternatively a disk could be used in place of a substantially annular shaped element. The hole could then be formed when the disc is hot deformed.

Préférentiellement selon l'invention, l'élément de fixation 7', 27' est un alliage à base magnésium, à base titane, à base zirconium, à base fer, à base cobalt, à base or, à base palladium ou à base platine. Plus précisément, un élément de fixation 7', 27' formé par un alliage à structure au moins partiellement amorphe du type ZrTiCuNiBe, PdCuNiP ou PtCuNiP ont chacun donné satisfaction.Preferably, according to the invention, the fastening element 7 ', 27' is a magnesium-base, titanium-based, zirconium-based, iron-based, cobalt-based, gold-based, palladium-based or platinum-based alloy. . More specifically, a fixing element 7 ', 27' formed by an alloy with at least partially amorphous structure of the ZrTiCuNiBe, PdCuNiP or PtCuNiP type have each been satisfactory.

L'élément de fixation 7', 27' peut être formé à partie d'une bande ou d'un fil puis être découpé dedans. Une trempe rapide sur disque (appelé « melt spinning » en anglais) ou une coulée suivie d'une trempe peuvent être envisagées.The fastening element 7 ', 27' can be formed from a strip or wire and then cut into it. A fast hardening on disk (called "melt spinning" in English) or a casting followed by quenching can be envisaged.

Le procédé selon l'invention se poursuit avec la deuxième étape b) destinée à enfoncer partiellement la pièce horlogère 3, 23 dans l'élément de fixation 7', 27' chauffé entre sa température de transition vitreuse Tg et sa température de cristallisation Tx afin de former un ensemble pièce horlogère 3, 23 - élément de fixation 7, 27 comme illustré aux figures 4 et 7.The method according to the invention continues with the second step b) intended to partially drive the watch part 3, 23 into the fastening element 7 ', 27' heated between its glass transition temperature Tg and its crystallization temperature Tx in order to to form a watch-piece assembly 3, 23 - fixing element 7, 27 as illustrated in FIGS. figures 4 and 7 .

En effet, l'élément de fixation 7', 27' en alliage métallique au moins partiellement amorphe, quand il est chauffé entre sa température de transition vitreuse Tg et sa température de cristallisation Tx, voit sa viscosité chuter jusqu'à permettre la pièce horlogère 3, 23 à pouvoir être enfoncée par simple poussée. Comme visible aux figures 4 et 7, l'élément de fixation 7', 27' se déforme alors pour finalement former l'élément de fixation 7, 27 en recouvrement partiel de la pièce horlogère 3, 23.Indeed, the at least partially amorphous metallic alloy fastener element 7 ', 27', when it is heated between its glass transition temperature Tg and its crystallization temperature Tx, sees its viscosity drop down to allow the watch piece 3, 23 can be pushed by simple push. As visible to figures 4 and 7 the fixing element 7 ', 27' then deforms to finally form the fastening element 7, 27 in partial overlap of the watch part 3, 23.

Selon une variante du premier mode de réalisation illustrée aux figures 10 & 11, lors de cette étape b), le procédé permet également à la pièce horlogère 13 de voir également son (ou ses) évidement(s) 12 être au moins partiellement rempli par l'élément de fixation 17 en plus dudit recouvrement expliqué ci-dessus. On comprend immédiatement que cette variante autorise un accrochage supérieur par l'augmentation de la surface de contact entre l'élément de fixation 17 et la pièce horlogère 13.According to a variant of the first embodiment illustrated in FIGS. Figures 10 & 11 during this step b), the method also allows the watch part 13 to also see its (or its) recess (s) 12 be at least partially filled by the fastening element 17 in addition to said recovery explained above . It is immediately understood that this variant allows a higher attachment by increasing the contact surface between the fastening element 17 and the watch part 13.

Dans le but de garantir une géométrie prédéterminée de l'élément de fixation à la fin de l'étape b), un gabarit peut être utilisé pour limiter la déformation de l'élément de fixation 7, 17, 27 selon certaines cotes telles que celle de la section du trou 8, 18, 28 et celle de la paroi périphérique de l'élément de fixation 7, 17, 27, voire, comme expliqué ci-dessus, former le trou 8, 18, 28 dans le disque d'ébauche de l'élément de fixation.In order to guarantee a predetermined geometry of the fixing element at the end of step b), a template can be used to limit the deformation of the fastening element 7, 17, 27 according to certain dimensions such as that the section of the hole 8, 18, 28 and that of the peripheral wall of the fixing element 7, 17, 27, or, as explained above, forming the hole 8, 18, 28 in the roughing disk of the fastener.

De manière additionnelle au gabarit ou de manière isolée, une entretoise peut être utilisée lors de l'étape b) afin de garantir la profondeur de pénétration de la pièce horlogère 3, 13, 23 dans l'élément de fixation 7, 17, 27. Cette entretoise est par exemple utilisée pour garantir qu'une épaisseur minimale de 50 µm de l'élément de fixation 7, 17, 27 reste après l'étape b), c'est-à-dire, pour la première alternative des figures 8 et 12, qu'il y ait une minimale de 50 µm d'élément de fixation 7, 17, 27 entre la portée 6 et la pièce horlogère 3, 13, 23.In addition to the template or in isolation, a spacer can be used in step b) to ensure the depth of penetration of the watch part 3, 13, 23 into the fastener 7, 17, 27. This spacer is used, for example, to ensure that a minimum thickness of 50 μm of the fixing element 7, 17, 27 remains after step b), that is to say, for the first alternative of figures 8 and 12 there must be a minimum of 50 μm of fixing element 7, 17, 27 between the bearing surface 6 and the watch part 3, 13, 23.

De manière optionnelle, après l'étape b) et avant l'étape c) expliquée ci-dessous, le procédé peut comporter une étape intermédiaire d) destinée à maintenir l'ensemble pièce horlogère 3, 13, 23 - élément de fixation 7, 17, 27 au-dessus de la température de transition vitreuse Tg de l'élément de fixation 7, 17, 27 afin de rendre plus ductile l'élément de fixation 7, 17, 27. En effet, un tel maintien en température permet d'initier une cristallisation notamment au niveau du trou 8, 18, 28 propre à faciliter l'étape finale c) expliquée ci-dessous.Optionally, after step b) and before step c) explained below, the method may comprise an intermediate step d) intended to hold the timepiece assembly 3, 13, 23 - fastening element 7, 17, 27 above the glass transition temperature Tg of the fixing element 7, 17, 27 in order to make the fixing element 7, 17, 27 more ductile. Indeed, such a temperature maintenance makes it possible to initiating a crystallization in particular at the hole 8, 18, 28 able to facilitate the final step c) explained below.

Enfin, le procédé se termine avec l'étape c) destinée à chasser un axe 5, 25 dans le trou 8, 18, 28 de l'élément de fixation 7, 17, 27 pour former l'assortiment horloger 1, 11, 21, c'est-à-dire en un ensemble solidaire formé d'un axe 5, 25, d'un élément de fixation 7, 17, 27 et d'une pièce horlogère 3, 13, 23.Finally, the process ends with step c) intended to drive an axis 5, 25 into the hole 8, 18, 28 of the fixing element 7, 17, 27 for forming the watchmaking assortment 1, 11, 21, that is to say a unitary assembly formed of an axis 5, 25, of a fastening element 7, 17, 27 and a watch part 3, 13, 23.

Selon une première alternative de l'étape c), l'élément de fixation 7, 17 est plaqué contre la portée 6, 26 de l'axe 5, 25 comme illustré aux figures 4-5, 8 et 12. Selon une deuxième alternative de l'étape c), la pièce horlogère 3, 13, 23 est plaquée contre la portée 6,26 de l'axe 5,25 comme illustré à la figure 9.According to a first alternative of step c), the fastening element 7, 17 is pressed against the bearing surface 6, 26 of the axis 5, as illustrated in FIGS. Figures 4-5 , 8 and 12 . According to a second alternative of step c), the timepiece 3, 13, 23 is pressed against the bearing surface 6.26 of the axis 5.25 as illustrated in FIG. figure 9 .

On comprend, avantageusement selon le premier mode de réalisation de l'invention, que la pièce horlogère 3, 13, 23, comportant un ajourage 4, 14, 24 qui s'étend autour du trou 8, 18, 28 de l'élément de fixation 7, 17, 27 en ayant une plus grande section, ne subit qu'une contrainte minimale, voire aucune contrainte, lors de l'étape c), c'est-à-dire que la quasi-totalité, voire la totalité, de la contrainte de chassage exercée lors de l'étape c) sera supportée par l'élément de fixation 7, 17, 27. Cela permet de laisser un interstice, c'est-à-dire une zone sans matière comme visible aux figures 8, 9 et 12, entre la paroi de la pièce horlogère 3, 13, 23 délimitant l'ajourage 4, 14, 24 et le diamètre externe de l'axe 5, 25 contre lequel l'élément de fixation 7, 17, 27 est chassé.It is understood, advantageously according to the first embodiment of the invention, that the timepiece 3, 13, 23, having an opening 4, 14, 24 which extends around the hole 8, 18, 28 of the element of fixation 7, 17, 27 having a larger section, undergoes only minimal stress, or even no stress, during step c), that is to say that almost all or all, of the driving force exerted during step c) will be supported by the fixing element 7, 17, 27. This allows to leave a gap, that is to say an area without material as visible to figures 8 , 9 and 12 between the wall of the timepiece 3, 13, 23 delimiting the opening 4, 14, 24 and the outer diameter of the axis 5, against which the fixing element 7, 17, 27 is driven.

Selon un deuxième mode de réalisation d'assortiment horloger 31, 41, 51, le procédé selon l'invention comporte une première étape a') destinée à fabriquer une pièce horlogère 33, 43, un élément de fixation en alliage métallique au moins partiellement amorphe et un organe de chassage 39, 49 muni d'un trou 38, 48.According to a second embodiment of watchmaking assortment 31, 41, 51, the method according to the invention comprises a first step a ') intended to manufacture a watch part 33, 43, an at least partially amorphous metal alloy fastener and a driving member 39, 49 provided with a hole 38, 48.

Sans être illustrés, la pièce horlogère 33, 43 et l'élément de fixation peuvent être de forme sensiblement identique à ceux 3, 13, 23, 7', 27' du premier mode de réalisation. On comprend donc que la forme de l'élément de fixation n'a pas une importance primordiale. Préférentiellement selon l'invention, l'organe de chassage 39, 49 est en forme de rondelle et comporte un trou 38, 48 dont la géométrie est importante d'être maîtrisée.Without being illustrated, the timepiece 33, 43 and the fixing element may be substantially identical in shape to those 3, 13, 23, 7 ', 27' of the first embodiment. It is therefore understood that the shape of the fastener is not of paramount importance. Preferably according to the invention, the driving member 39, 49 is in the form of a washer and has a hole 38, 48 whose geometry is important to be controlled.

Le procédé selon l'invention se poursuit avec la deuxième étape b') destinée à enfoncer partiellement la pièce horlogère 33, 43 et l'organe de chassage 39, 49 dans l'élément de fixation chauffé entre sa température de transition vitreuse Tg et sa température de cristallisation Tx afin de former un ensemble pièce horlogère 33, 43 - élément de fixation 37, 47 - organe de chassage 39, 49.The method according to the invention continues with the second step b ') intended to partially drive the watch part 33, 43 and the driving member 39, 49 into the fastening element heated between its glass transition temperature Tg and its crystallization temperature Tx in order to form a watch-piece assembly 33, 43 - fixing element 37, 47 - hunting member 39, 49.

En effet, l'élément de fixation en alliage métallique au moins partiellement amorphe, quand il est chauffé entre sa température de transition vitreuse Tg et sa température de cristallisation Tx, voit sa viscosité chuter jusqu'à permettre la pièce horlogère 33, 43 à pourvoir être enfoncée par simple poussée. Comme visible aux figures 13 et 16, l'élément de fixation se déforme alors pour finalement former l'élément de fixation 37, 47 en recouvrement partiel de la pièce horlogère 33, 43 et de l'organe de chassage 39, 49.Indeed, the at least partially amorphous metal alloying element, when it is heated between its glass transition temperature Tg and its crystallization temperature Tx, sees its viscosity drop to allow the watch part 33, 43 to be filled to be pushed by simple push. As visible to figures 13 and 16 the fixing element then deforms to finally form the fastening element 37, 47 in partial overlap of the watch part 33, 43 and the driving member 39, 49.

Selon une variante du deuxième mode de réalisation illustrée à la figure 16, lors de cette étape b'), le procédé permet également à la pièce horlogère 43 de voir également son (ou ses) évidement(s) 42 et/ou l'organe de chassage 49 de voir également son (ou ses) évidement(s) 46 être au moins partiellement rempli par l'élément de fixation 47 en plus dudit recouvrement expliqué ci-dessus. On comprend immédiatement que cette variante autorise un accrochage supérieur par l'augmentation de la surface de contact entre l'élément de fixation 47 et la pièce horlogère 43 et/ou l'élément de fixation 47 et l'organe de chassage 49.According to a variant of the second embodiment illustrated in FIG. figure 16 during this step b '), the method also allows the watch part 43 to also see its (or its) recess (s) 42 and / or the hunting member 49 to see also its (or its) recess ( s) 46 be at least partially filled by the fastener 47 in addition to said overlap explained above. It is immediately understood that this variant allows a higher attachment by increasing the contact surface between the fixing element 47 and the watch part 43 and / or the fixing element 47 and the driving member 49.

Dans le but de garantir une géométrie prédéterminée de l'élément de fixation à la fin de l'étape b'), un gabarit peut être utilisé pour limiter la déformation de l'élément de fixation 37, 47 selon certaines cotes telles que celle de la paroi interne et celle de la paroi périphérique de l'élément de fixation 37, 47.In order to guarantee a predetermined geometry of the fixing element at the end of step b '), a template can be used to limit the deformation of the fixing element 37, 47 according to certain dimensions such as that of the inner wall and that of the peripheral wall of the fixing element 37, 47.

De manière additionnelle au gabarit ou de manière isolée, une entretoise peut être utilisée lors de l'étape b') afin de garantir la profondeur de pénétration de la pièce horlogère 33, 43 et de l'organe de chassage 39, 49 dans l'élément de fixation 37, 47. Cette entretoise est par exemple utilisée pour garantir qu'une épaisseur minimale de 50 µm de l'élément de fixation 37, 47 entre la pièce horlogère 33, 43 et de l'organe de chassage 39,49.In addition to the template or in isolation, a spacer may be used during step b ') to guarantee the depth of penetration of the watch part 33, 43 and the driving member 39, 49 in the fixing element 37, 47. This spacer is for example used to ensure that a minimum thickness of 50 microns of the fastener 37, 47 between the watch part 33, 43 and the driving member 39.49.

Enfin, le procédé se termine avec l'étape c') destinée à chasser un axe 35 dans le trou 38, 48 de l'organe de chassage 39, 49 pour former l'assortiment horloger 31, 41, 51, c'est-à-dire en un ensemble solidaire formé d'un axe 35, d'un organe de chassage 39, 49, d'un élément de fixation 37, 47 et d'une pièce horlogère 33, 43.Finally, the process ends with step c ') intended to drive an axis 35 in the hole 38, 48 of the driving member 39, 49 to form the watchmaking assortment 31, 41, 51, that is, that is to say in an integral assembly formed of an axis 35, a driving member 39, 49, a fixing member 37, 47 and a timepiece 33, 43.

Selon une première alternative de l'étape c'), l'organe de chassage 39, 49 est plaqué contre la portée 36 de l'axe 35 comme illustré aux figures 14 et 16. Selon une deuxième alternative de l'étape c'), la pièce horlogère 33, 43 est plaquée contre la portée 36 de l'axe 35 comme illustré à la figure 15.According to a first alternative of step c '), the driving member 39, 49 is pressed against the bearing surface 36 of the shaft 35 as illustrated in FIGS. figures 14 and 16 . According to a second alternative of step c '), the timepiece 33, 43 is pressed against the bearing surface 36 of the axis 35 as illustrated in FIG. figure 15 .

On comprend, avantageusement selon le deuxième mode de réalisation de l'invention, que la pièce horlogère 33, 43, comportant un ajourage 34, 44 qui s'étend autour du trou 38, 48 de l'organe de chassage 39, 49 en ayant une plus grande section et, ne subit aucune contrainte lors de l'étape c'), c'est-à-dire que la totalité de la contrainte de chassage exercée lors de l'étape c') sera supportée par l'organe de chassage 39, 49. Cela permet de laisser un interstice, c'est-à-dire une zone sans matière comme visible aux figures 14, 15 et 16, entre la paroi de la pièce horlogère 33, 43 délimitant l'ajourage 34, 44 et le diamètre externe de l'axe 35 contre lequel l'organe de chassage 39, 49 est chassé.It is understood, advantageously according to the second embodiment of the invention, that the watch part 33, 43, having an opening 34, 44 which extends around the hole 38, 48 of the driving member 39, 49 having a larger section and, does not undergo any stress during step c '), that is to say that all of the driving force exerted during step c') will be supported by the body of hunting 39, 49. This allows to leave a gap, that is to say an area without matter as visible to Figures 14, 15 and 16 between the wall of the watch part 33, 43 delimiting the opening 34, 44 and the outer diameter of the axis 35 against which the driving member 39, 49 is driven.

En outre, conformément à ces deux modes de réalisation, on comprend, avantageusement selon l'invention, que l'élément de fixation 7, 17, 27, 37, 47 en alliage métallique au moins partiellement amorphe va prendre parfaitement la forme d'une partie de la pièce horlogère 3, 13, 23, 33, 43, et, éventuellement, de l'organe de chassage 39, 49, lui autorisant en combinaison à la rugosité de surface de la pièce horlogère 3, 13, 23, 33, 43 et, éventuellement, de l'organe de chassage 39, 49 à s'y agripper sans qu'il ne soit plus nécessaire de mettre en oeuvre un collage.In addition, according to these two embodiments, it is advantageously understood according to the invention, that the fastening element 7, 17, 27, 37, 47 of at least partially amorphous metal alloy will take perfectly the shape of a part of the timepiece 3, 13, 23, 33, 43, and possibly the driving member 39, 49, allowing it in combination with the surface roughness of the watch part 3, 13, 23, 33, 43 and possibly the driving member 39, 49 to grip it without it is no longer necessary to implement a bonding.

Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art. En particulier, la géométrie de la pièce horlogère 3, 13, 23, 33, 43 peut différer sans que les avantages de la présente description soient perdus.Of course, the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art. In particular, the geometry of the timepiece 3, 13, 23, 33, 43 may differ without the advantages of the present description being lost.

L'étape c), c') de chassage de l'axe 5, 25, 35 pourrait également se faire à une température supérieure à la température de transition vitreuse Tg de l'alliage métallique au moins partiellement amorphe afin de ramollir légèrement ce dernier pour diminuer les contraintes sur le matériau de la pièce horlogère 3, 13, 23, 33, 43 tout en conservant une bonne tenue. Ainsi, à titre d'exemple, le procédé pourrait comporter une première phase c1) destinée à chauffer l'axe au-dessus de la température de transition vitreuse de l'élément de fixation et une deuxième phase c2) destinée à chasser l'axe dans le trou de l'élément de fixation ou de l'organe de chassage afin d'élever la température de la surface de contact de l'élément de fixation au-dessus de sa température de transition vitreuse dans le but de ramollir localement l'élément de fixation pour diminuer les contraintes sur le matériau de la pièce horlogère tout en conservant une bonne tenue.Step c), c ') of driving the axis 5, 25, 35 could also be done at a temperature above the glass transition temperature Tg of the at least partially amorphous metal alloy to slightly soften the latter to reduce the stress on the material of the watch part 3, 13, 23, 33, 43 while maintaining a good performance. Thus, by way of example, the method could comprise a first phase c1) intended to heat the axis above the glass transition temperature of the fixing element and a second phase c2) intended to drive the axis in the hole of the fastener or the driving member to raise the temperature of the contact surface of the fastener above its glass transition temperature for the purpose of locally softening the fixing element to reduce the stresses on the material of the watch piece while maintaining a good performance.

Ce chauffage faciliterait également la formation d'un trou par le passage de l'axe dans le cas où un disque est utilisé pour former l'élément de fixation lors de l'étape a). Cette configuration permettrait enfin de diminuer les risques de désolidarisation de l'ensemble formé à l'étape b), b').This heating would also facilitate the formation of a hole through the passage of the axis in the case where a disc is used to form the fastener in step a). This configuration would finally reduce the risk of separation of the assembly formed in step b), b ').

Il est également possible de jouer sur la structuration de surface de l'axe 5, 25, 35 afin d'améliorer l'accroche lors de l'étape c), c') de chassage.It is also possible to play on the surface structuring of the axis 5, 25, 35 in order to improve the grip during step c), c ') of driving.

De plus, l'utilisation d'un axe 5, 25, 35 à faible coefficient de dilatation est préférable pour limiter le retrait lors du refroidissement qu'il soit effectué lors de l'étape b), b') ou c), c').In addition, the use of a low coefficient of expansion axis 5, 25, 35 is preferable in order to limit the shrinkage during cooling that is carried out during step b), b ') or c), c ').

Enfin, à la lecture des procédés ci-dessus, on comprend qu'il est possible de former plusieurs ensembles en même temps. Ainsi, à titre d'exemple, les pièces horlogères pourraient être maintenues solidaires de leur plaquette de gravage et les éléments de fixation de leur bande ou de leur fil afin de les monter les unes sur les autres pour l'étape b), b') de solidarisation (appelé « wafer scale assembling » en anglais). De manière similaire, plusieurs ensembles pourraient être chassés sur leur axe respectif lors de la même étape c), c').Finally, upon reading the above methods, it is understood that it is possible to form several sets at the same time. Thus, for example, the watch parts could be held integral with their etching plate and the fastening elements of their band or wire to mount them on each other for step b), b ' ) of solidarity (called "wafer scale assembly" in English). Similarly, several sets could be driven on their respective axis during the same step c), c ').
