Definitions

  • the present invention relates to a method for producing a timepiece element.
  • the invention relates to a method for manufacturing a timepiece element that overcomes the aforementioned drawbacks of the prior art by providing a platinum that is less expensive and faster to produce while having a precision at least equal to that of the prior art.
  • the method uses the advantageous shaping properties of the amorphous materials by applying it to a simple forging process.
  • these amorphous metals have the particular characteristic of softening while remaining amorphous in a temperature range [Tg - Tx] given specific to each alloy (with Tg: glass transition temperature and Tx: crystallization temperature). It is thus possible to shape them under a low stress of the order of MPa and at low temperatures down to at least 200 ° C depending on the material. This then makes it possible to reproduce fine and precise geometries very precisely because the viscosity of the alloy decreases sharply and the latter thus marries all the details of the dies. This is then typically suitable for a complex and precise piece such as a watch plate.
  • An advantage of this embodiment is that it is simpler to perform and does not require the use of an amorphous preform. Indeed, such a method uses simple techniques for making parts by casting, thus making the tooling to use less complex associated with the use of the amorphous zone of said material. As for the first embodiment, this makes it possible to reproduce fine and precise geometries very precisely because the viscosity of the alloy decreases sharply and the latter thus marries all the details of the mold. This simplification then allows a substantial financial gain.
  • Another advantage stems from this ability to perfectly match the shapes of the mold. Indeed, it can be expected to couple the platinum manufacturing steps with those of decorations at the same time. This solution is conceivable by producing the decorations directly on the mold or the dies in order to reproduce them directly during the manufacture of the plate. This allows a new saving of time and money.
  • amorphous materials allows the use of stronger alloys said to high mechanical performance.
  • manufacture of the plate is no longer subject to the machining of brass. It is therefore understood by using high mechanical performance materials, it also becomes possible to reduce the dimensions of said platen including its thickness with the same mechanical characteristics.
  • a watch movement consists of a plate on which is fixed the mechanism of the watch.
  • the plate supports the energy storage members, the regulating members and the driving members of said movement.
  • the present invention consists of a manufacturing method 1 of elements such as a bridge or a plate for a timepiece.
  • elements such as a bridge or a plate for a timepiece.
  • the realization of the plate will be taken as an example, the realization of the decks of the watch being identical.
  • a first embodiment consists of using hot forming with the aid of a press.
  • the first step A 1 consists first of all in making the matrices of the stage. These matrices each have an internal face comprising the negative imprint of the plate to be produced. These matrices are provided with means for the evacuation of surplus material. Of course, the realization of such matrices not being part of the object of the present invention, all the possible methods for making these matrices are conceivable.
  • this first step A 1 consists in providing the material in which the plate will be made.
  • the material used is an at least partially amorphous material.
  • a material so amorphous will be used, said material possibly being a precious metal or not.
  • the metal is an alloy.
  • amorphous material advantageously allows a reduction in dimensions.
  • the amorphous materials have deformation and elastic limit characteristics such that they can undergo higher stresses before deforming plastically.
  • a reduction of the dimensions and in particular of the thickness is possible.
  • next step B 1 is to manipulate the whole in order to achieve said element.
  • step B 1 is to provide a preform of amorphous material.
  • This preform consists of a piece of appearance and dimensions similar to the final piece.
  • the preform is in the form of a disk. It is then necessary for said preform to always have an amorphous structure.
  • the dies are placed in the hot press. These matrices are then heated until the material-specific temperature is reached, preferably between its glass transition temperature Tg and its crystallization temperature Tx.
  • the preform is placed on one of the dies. Pressure is then exerted on the preform by bringing the matrices together to replicate their shape on said amorphous metal preform. This pressing operation is performed for a predefined period of time. Once this time has elapsed, the dies open so that the cooling step C of the molded part can begin.
  • This hot forming principle advantageously offers a high precision of the parts obtained.
  • This accuracy is allowed by maintaining the amorphous metal material at a temperature between Tg and Tx. Indeed, when an amorphous material is heated up to this interval temperatures, its viscosity decreases sharply passing for some materials from 10 20 Pa.s -1 to 10 5 Pa.s -1 . This then allows the amorphous material to better fill the spaces of said negative impressions of each matrix which facilitates the production of complex parts.
  • the plate is made by casting, for example pouring a liquid metal into a mold.
  • step A 2 consists first of all in producing the platen mold by any possible method.
  • this first step is to provide the material in which the plate will be made.
  • the melting temperature of the amorphous metals is lower than that of crystalline metals, the implementation of the process is then facilitated. It can also be provided that the casting is of the injection type allowing the material in liquid form to better match the shapes of the mold.
  • step B 2 of shaping the material For this, the constituent material of the platen is then heated to be put in liquid form. Once liquefied, this material is injected into the mold.
  • the next step is to solidify said element.
  • This solidification consists of a cooling step called stage C.
  • This stage C is carried out rapidly in order to descend as quickly as possible to a temperature below Tg.
  • a cooling that is too slow allows the atoms to to structure in the form of mesh and thus to crystallize the metal whereas a fast cooling makes it possible to freeze the atoms in order to avoid that they are structured.
  • the purpose is to maintain the initial at least partially amorphous state
  • the aim is to obtain an amorphous or at least partially amorphous state.
  • the use of the metal casting and then the cooling step C to make amorphous metal is more accurate than its crystalline metal equivalent, Indeed, as the amorphous metal does not have a crystalline structure when it solidifies, the amorphous metal undergoes very little the effects of material removal due to solidification.
  • this solidification shrinkage can reach 5 to 6%, which means that the part has its size decreased by 5 to 6% during solidification. In the case of the amorphous metal, this shrinkage is about 0.5%.
  • the fourth step D then consists in recovering said platen once it has solidified
  • Step E consists in inserting in the plate complementary members such as ruby bearings used for example to support the axes of the gear wheels forming the gear of the watch.
  • this insertion of ruby bearings, during step E is performed by hot crimping.
  • the plate is heated locally to the place where said bearing must be inserted, at a temperature between Tg and Tx. Once the place is warmed up, the ruby landing is approached from the place and then pushed into the stage.
  • the bearing is heated to a temperature above Tg and then pressed into the plate.
  • the heat released by said bearing locally heats the plate to a temperature above Tg facilitating insertion.
  • Step E thus allows a better grip of the bearing in the plate thanks to the ability of the amorphous material to marry the contours. Step E also saves time and money because of its simplicity.
  • the bearing is directly placed in the mold or on the dies and inserted during steps B 1 or B 2 .
  • these bearings are directly integrated in the cast or stamped form, during the steps B 1 or B 2 forming a monoblock element that is to say that the bearings are an integral part of the element and not a reported part.
  • the method 1 may also provide a step F of recrystallization of said platinum.
  • the platen is heated to reach a temperature at least equal to the crystallization temperature of the amorphous metal.
  • the cooling is then performed so that the atoms have time to structure.
  • This step can take place after the recovery step D (in double line at the figure 1 ) or after step E of insertion of the complementary organs (in simple line at the figure 1 ).
  • This recrystallization can be used to advantageously modify certain physical, mechanical or chemical properties of the material such as toughness, hardness or coefficient of friction.
  • a variant of method 1 consists in making decorations in step B 1 or B 2 of the embodiments above.
  • the decorations of the platinum such as decorations type Geneva coast, beading, satin or guilloche are made directly in the negative impressions of said mold or said dies.
  • this variant also makes it possible to do without the heavy tools currently used to make these decorations in series. It is understood that the method 1 allows the realization of a platinum decorated more quickly and, incidentally, cheaper way.
  • step B 2 of the second embodiment it may be provided to directly perform the tapping screw threads in step B 2 of the second embodiment. This operation would then be performed during casting by inserts provided in the mold.
  • the plate may be square or rectangular in shape and that the ruby bearings are not the only complementary members that can be inserted.
