Definitions

  • the invention relates to a piece for a watch movement and in particular to such a part which is not or not very sensitive to magnetic fields as all or part of a cog, all or part of a raqueting system or any or part of an exhaust system.
  • This type of material has the advantage of being easily machinable, in particular to be able to cut and has, after quenching and tempering treatments, high mechanical properties very interesting for the realization of parts pivoting a clockwork movement.
  • These steels have, after heat treatment, a wear resistance and a hardness which are particularly high.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing an alternative material enjoying the same advantages of steels 15P and 20AP without being sensitive to magnetic fields or corrosion.
  • the invention relates to a micromechanical component for a watch movement comprising a metal body formed with a single material characterized in that said single material is of high-grade austenitic steel type.
  • the micromechanical part is, surprisingly, chemically and physically stable with the use of a single totally homogeneous material even in case of exposure external magnetic fields or oxidizing atmospheres.
  • the invention relates to a timepiece characterized in that it comprises at least one micromechanical component according to one of the preceding variants.
  • the movement 1 preferably comprises a resonator 3 comprising a balance 5 and a spiral 7 intended to regulate the movement 1.
  • the resonator 3 is preferably pivotally mounted, in particular by means of a ferrule 26 of the spiral 7 mounted on an axis, between a bridge 2 and a plate 4 and comprises a racking system 21 mounted on the bridge 2 mainly comprising a racket 17. It can be seen, at the figure 1 , that the bridge 2 is fixed on the plate 4 in particular by means of a screw 28.
  • the movement 1 also comprises an exhaust system 9 comprising an anchor 11 of the Swiss type and an escape wheel 13 intended to distribute the gear 15 of the movements of the resonator 3 but also to maintain it.
  • the exhaust system 9 is preferably mounted between two bridges 6, 8 and a plate 4.
  • the gear train 19 is intended to transmit the energy of the barrel (not shown) to the resonator but also to recharge the barrel using, for example, a winding stem 19 or an oscillating weight 23.
  • micromechanical parts are currently formed from 15P and 20AP steels and are therefore sensitive to magnetic fields and corrosion. If their sensitivity can be troublesome directly in the case of a moving part, it can also be indirectly by influencing another adjacent piece.
  • the invention relates to a micromechanical component for a watch movement comprising a metal body formed with a single material of the austenitic steel type with a high interstitial content.
  • austenitic steel comprises an alloy comprising predominantly iron in substantially austenitic form. Indeed, in any production, it is difficult to guarantee that the whole structure is austenitic.

It is thus clear that the austenitic steel according to the invention may comprise only interstitial carbon atoms, only interstitial nitrogen atoms or both carbon atoms and nitrogen atoms.
  • the properties are optimal for the manufacture of timepieces for a sum of the percentages of carbon and nitrogen in total mass of the metal body of between 0.75% and 0.95% and / or for a ratio of the percentages of carbon and nitrogen in total mass of the metal body between 0.35 and 0.55.

  • a chromium manganese austenitic steel giving complete satisfaction whose sum, that is to say C + N, is substantially equal to 0.85% by total mass of the body metal and the ratio of percentages of carbon and nitrogen in total mass of the metal body, that is to say C / N, is substantially equal to 0.44.
  • any gammagene element that is to say, promoting the phase y of a steel, can replace all or part of the manganese to promote the austenitic phase such as, for example, cobalt or copper.
  • the austenitic steel with a high interstitial content according to the invention may also comprise bismuth, lead, tellurium, selenium, sulfur and / or sulfur and manganese (when the steel does not contain of manganese) as an adjuvant to improve the machinability of said micromechanical part.
  • these compounds used alone or in combination as adjuvants allowed to form discontinuities of matter in the material capable of limiting the chip length and, therefore, facilitate the machining of said material.

  • micromechanical parts can be envisaged, even if they are not usually made of 15P steel or 20AP steel.
  • a high interstitial austenitic steel does not require heavy implementation steps including no curing treatment of the material to a certain thickness, no chemical protection treatment of the material or any magnetic shielding treatment.
  • austenitic steels with high interstitial content are in line with the high demands of watchmaking without special treatment dedicated to protection against magnetic fields and corrosion.
  • step a) consists mainly of casting a high interstitial austenitic steel having at least one non-metal as an interstitial atom such as nitrogen and / or carbon in a homogeneous proportion. that is to say in the entire metal body, between 0.15% and 1.2% of the total mass of said metal body.
  • the sum of the percentages of carbon and nitrogen in total mass of the metal body is between 0.75% and 0.95% and / or the ratio of percentages of carbon and nitrogen in total mass of the metal body is between 0.35 and 0.55.
  • the austenitic steel with a high interstitial content according to the invention is of the stainless steel austenitic type comprising at least 10% of chromium and at least 5% of nickel and / or at least 5% of manganese, the remainder being in iron.
  • a chromium manganese austenitic steel whose sum, that is to say C + N, is substantially equal to 0.85% by total weight of the metal body and the ratio of percentages of carbon and nitrogen in total mass of the metal body, that is to say C / N, is substantially equal to 0.44, gives complete satisfaction.
  • the austenitic steel with a high interstitial content according to the invention may also comprise bismuth, lead, tellurium, selenium, sulfur and / or sulfur and manganese (when the steel does not contain of manganese) as an adjuvant to improve the machinability of said micromechanical part.
  • step b) comprises a phase of deformation of said material in band form. Then the phase deformation is followed by a cutting step to form said micromechanical part in a part of the strip.
  • the cutting phase in the first embodiment, preferably comprises a drawing of a blank of the workpiece and then a machining of the functional surfaces, possibly followed by a grinding.
  • the first embodiment makes it possible, by way of example, to form wheel planks 14, gable planks 18, racket plank 17, escape wheel planks 13, ferrules 26 or a rod 10 anchor 11.
  • step b) comprises a phase of deformation of said material in the form of bar or wire. Then the deformation phase is followed by a cutting step to form said micromechanical part in a part of the bar or wire.
  • the cutting phase which can be assimilated to a turning, in the second embodiment, preferably comprises a cutting of the functional surfaces, possibly followed by a grinding.
