Definitions

  • the invention relates to a method for the economical manufacture of a display component or clockwork switch comprising at least one aspect surface.
  • the invention also relates to a watch comprising at least one display or switching component produced by this method.
  • the invention relates to the field of display components or clock switch.
  • the invention proposes to develop an alternative method, making it possible to achieve at controlled cost watch display components or switching devices comprising at least one aspect surface, guaranteeing the visual and surface reproducibility of these surfaces. in appearance, with improved production reliability compared to the prior art.
  • the invention relates to a manufacturing method according to claim 1.
  • the invention also relates to a watch comprising at least one display or switching component produced by this method.
  • the invention proposes to reduce both the cost and the mass of trim components or switch, while ensuring a flawless appearance for such pieces of appearance, and reducing as much as possible manufacturing scrap.
  • the invention proposes to make a shell, preferably hollow, whose surface portion is made of a material compatible with a finishing machining to obtain a regular surface condition and very low roughness.
  • This surface portion is made of a sufficient thickness to ensure the homogeneity of the material, and thus ensure the quality of the final appearance after machining.
  • the preferred finishing machining is a tool diamond.
  • the invention thus relates to a method for the economical manufacture of a display component 1 or a watch-making switch, constituted by a needle 11, an appliqué 12, or the like, comprising at least one surface of appearance 2 intended to be visible to the user of a watch or the like.
  • the method according to the invention can be implemented with a first reusable tooling 3, such as a mold or the like, or with a first consumable tool 3, such as a shell made of light polymeric material, such as PMMA, or other, itself made from other tools. Therefore, as soon as the blank 4 is formed entirely, one can choose either to leave it in the first tool 3 for at least part of the following operations, or to separate it.
  • a first reusable tooling 3 such as a mold or the like
  • a first consumable tool 3 such as a shell made of light polymeric material, such as PMMA, or other, itself made from other tools. Therefore, as soon as the blank 4 is formed entirely, one can choose either to leave it in the first tool 3 for at least part of the following operations, or to separate it.
  • the first tooling 3 comprises a peripheral contact layer 31, for example a metallized layer (by PVD or equivalent) to allow galvanic growth of the blank 4, this peripheral contact layer 31 may be, optionally, retained or eliminated for the rest of the operations. It may in particular remain in the area of the excess thickness 5, and be machined with it during the diamondizing operation.
  • a peripheral contact layer 31 for example a metallized layer (by PVD or equivalent) to allow galvanic growth of the blank 4
  • this peripheral contact layer 31 may be, optionally, retained or eliminated for the rest of the operations. It may in particular remain in the area of the excess thickness 5, and be machined with it during the diamondizing operation.
  • the blank 4 is produced in this envelope material with an initial thickness E greater than or equal to 50 microns.
  • component 1 is made with at least one surface of appearance 2 bordered by a projecting edge 9, and during diamonding, this projecting edge 9 is produced which delimits this surface of aspect 2.
  • all the surfaces of appearance 2 intended to remain visible are diamond-coated, removing all or part of the excess thickness 5, and, when the component 1 in comprises, all the projecting ridges 9 which delimit these surfaces of aspect 2.
  • one removes the whole of the extra thickness 5 during this diamondizing operation.
  • it is completed to remove the extra thickness 5 during diamond recovery, which may be made necessary by a particular geometry of the component 1.
  • At least one such surface of appearance 2 is dotted so as to remain visible, by removing all or part of the excess thickness 5, with a surface state between 2 nm Ra and 100 nm Ra.
  • a residual thickness ER of at least 5 microns of the blank 4 is maintained at each aspect surface 2.
  • At least 50% of the initial thickness E of the blank 4 is removed.
  • the interior material is selected from alloys of copper and / or aluminum and / or zinc.
  • a brass is chosen for the interior material.
  • an aluminum alloy is chosen for the interior material.
  • a zinc alloy is chosen for the interior material.
  • a POM or PS or PC or a polymer is chosen for the interior material.
  • the charged interior material is chosen to render it electrical conductor.
  • the envelope material is chosen as the interior material. It is thus possible to produce a component 1, in particular a hollow component 1 with a second cavity 70, in a single material. More particularly, the blank 4 may be made by galvanic growth, for example in Ni-P, and the reinforcement 7 can be made by continuing to grow Ni-P directly; However, it is then possible to modify the electrical parameters in order to save manufacturing cycle time since, for the frame 7, no grain fineness or absence of defects is sought, the only function of the frame 7 being a mechanical maintenance of the component 1.
  • the shell material different from said interior material is chosen.
  • the nickel-phosphorus envelope material is chosen.
  • the reinforcement 7 is bonded in the first cavity 6 of the blank 4.
  • the reinforcement 7 is introduced into and maintained by deformation in the first cavity 6 of the blank 4 held in the first tool 3.
  • the reinforcement 7 is made by stamping between a punch 82 and a matrix 81 constituting together such a second tool 8, as visible on the figure 3 .
  • the hollow armature 7 is produced with a second cavity 70 and / or having at least one attachment foot 10.
  • the component 1 thus has a particularly low mass, which is present a finished surface finish that is flawless, and is ready to be assembled on a watch 100 or the like.
  • the component 1 is produced in the form of a needle 11 or a wall 12 or a numeral 13 or a symbol 14 or a monogram 15 or an indicator 16 or an index 17 or a window surround 18, or other similar component.
  • the invention can also be implemented with a single blank and several reinforcements, or several blanks and a single reinforcement, or several blanks and several reinforcements, for a single blank. component.
  • the invention also relates to a watch 100 comprising at least one component 1 display or switching made by the method according to the invention.
  • the diamond finish state of such a component is distinguished by the perfect quality of the surface condition (mirror) and the intersection of the faces that define sharp edges, that no other method of manufacture can provide.
