Definitions

  • the invention relates to a method of manufacturing a timepiece applique, comprising an upper surface intended to be seen by a user, and a lower surface for its support on a dial or a structure of a timepiece, and at least one foot projecting from said lower surface, for its attachment to such a dial or such a structure, according to which method is provided in a first operation with a profile or a bar in which the machining is carried out roughing said feet and said lower surface, before cutting said section or said bar in a second operation, then performing the machining again, with at least one final diamond coating operation, of said upper surface.
  • the invention also relates to a method of manufacturing an assembly comprising an applique and a timepiece dial.
  • the invention also relates to a method of manufacturing a timepiece comprising at least one such dial, and / or a structure carrying at least one applique produced by the method.
  • the invention relates to the field of watch dressing and display functions.
  • Horological appliques are essential elements of a timepiece, in particular a watch, helping to give it a particular appearance. As a result, their execution must be particularly careful, very reproducible, and free from any defect in surface finish. Perfect execution is made difficult by the very small size of these appearance components, and by their difficult grip. As a result, the reject rate can be high. This production is even more delicate when the appliques are of left shape, to adapt to the curvature of a dial, a flange, or a plate, and do not have a flat reference surface.
  • a casing material such as an amorphous metal alloy or with a nanocrystalline structure or an alloy of gold and / or silver and / or copper and / or rhodium and / or titanium and / or aluminum
  • a thick hollow blank of greater thickness, is produced in a first tool at 20 micrometers, of the casing material, with an extra thickness in relation to each aspect surface, with a first cavity for receiving a frame
  • an interior material is chosen for the production of a frame, we this reinforcement is produced and it is made integral with this first cavity, and at least one aspect surface remaining visible is machined by diamond-coating with a tool, removing all or part of the excess thickness of the blank.
  • the document EP3220209 in the name of NIVAROX_FAR SA describes an economical manufacturing process of a display or clockwork switch component according to which a first material is chosen which is easy to shape or to machine, and a slug is produced in this first material, a second material is chosen for the production of each aspect surface of the component, which is an amorphous metal alloy or of nanocrystalline structure or comprises nickel or nickel-phosphorus, or which is a pure metal or an alloy of gold and / or silver and / or copper and / or rhodium and / or titanium and / or aluminum, this piece is covered, at least on the surfaces intended to remain visible on the component, with a thick layer, of a thickness initial greater than 20 micrometers, of the second material; and at least one aspect surface is machined by diamond coating, removing all or part of the thick layer.
  • the invention proposes to define a method of manufacturing wall lights ensuring perfect subsequent positioning of the wall light on its support.

  • Such an applique 100 usually comprises an upper surface 10 intended to be seen by a user, and a lower surface 2 for its support on a dial or a structure of a timepiece.
  • this lower surface 2 can be directly glued to such a dial or such a structure, it generally comprises at least one foot 3.
  • Each foot 3 protrudes from this lower surface 2, and more particularly but not limited to a particular orientation in the 'space relative to the lower surface 2, for its attachment to such a dial or such a structure.
  • At least two cross machining is carried out so as to roughen each foot 3 with a polygonal contour with facets 4, 5, 6, 7.
  • At least one foot 3, and preferably each foot 3, is journalled so as to machine a substantially cylindrical surface 8 directly usable for fixing. of the applique 100 on its support in the timepiece.
  • a front groove 89 is produced, which is arranged to receive any possible burr or lip during a fitting of the applique 100 on. a dial or a structure by driving or hooping.
  • this journaling is carried out during the first operation, before the cutting operation.
  • a finishing machining of the lower surface 2 is carried out. More particularly, this curved lower surface 2 is produced.
  • the advantage of the present invention is to obtain parallel feet over their entire length, even if the lower surface 2 is curved, or, in general, has any profile.
  • this finishing machining of the lower surface 2 is carried out by diamond coating.
  • journaling operation makes it possible to obtain feet 3 which are of revolution, and in particular cylindrical, of the usual type.
  • the embodiment of the blank of the feet 3 by cross machining, in the form of a faceted polygonal foot also makes it possible to have an intrinsic orientation surface, for a unique and precise angular orientation of the applique 100 comprising such a polygonal foot on its support in a timepiece.
  • the invention also relates to a dial 200 of a timepiece comprising at least one applique 100 produced by this method.
  • this dial 200 comprises at least one polygonal opening 201, which is arranged to cooperate with a foot 3 comprising a polygonal contour with facets 4, 5, 6, 7, to ensure the exact angular orientation. of the wall lamp 100 comprising this polygonal foot 3.
  • Machining technologies by electro-erosion, laser, or other, today make it possible to make such non-circular openings, which were previously not possible with drilling tools, and difficult to achieve with precision in stamping, especially for substrates intended to be enamelled or to undergo a coating of any type.
  • this dial comprises at least one applique 100 comprising such a single polygonal foot 3.
  • the dial 200 comprises at least one circular opening 202, which is arranged to receive with clamping, at the level of the junctions between its facets, a foot 3 having a polygonal contour with facets 4, 5, 6, 7.
  • the invention also relates to a timepiece 300 comprising at least one such dial 200, according to one of the variants described above, and / or a structure 301 carrying at least one applique 100 produced by the method.
  • the timepiece 300 comprises a structure 301, which comprises, or else at least one polygonal opening 302 arranged to cooperate with a foot 3 comprising a polygonal contour with facets 4, 5, 6, 7, to ensure the exact angular orientation of the wall lamp 100 comprising this polygonal foot 3, or at least one circular opening 303 arranged to receive with clamping, at the level of the junctions between its facets, a foot 3 comprising a polygonal contour with facets 4, 5, 6 , 7.
  • this timepiece 300 is a watch.
