Definitions

  • the invention relates to a housing for wristwatches according to the preamble Claim 1.
  • a housing for wristwatches (DE 44 07 179 A1), which consists of there is a housing part accommodating the clockwork. This is through on one side a watch glass and closed on the other side by a lid. At least the housing part consists of a hardenable stainless steel with a carbon content > 0.4% and is made from the solid material by machining then hardened.
  • the object of the invention is to show a housing which at high Functionality has a high resilience.
  • the housing part preferably but also the outer cover that closes the housing on the underside from one hardenable, nickel-free stainless steel, which has a carbon content greater than 0.4% and in alloy chromium with a proportion greater than 12%, molybdenum with a proportion contains greater than 0.2% and vanadium with a proportion greater than 0.2%.
  • the hardenable steel is preferably one from the group X110 CrMoV 15 or X105 CrMo 17.
  • the outer housing part and / or the Lid also uses hardenable steel that has a carbon content greater than 0.1%, preferably between 0.1 and 6% and chromium greater than 12%, tungsten greater than 1.0%, Molybdenum greater than 0.2%, vanadium greater than 0.2%, greater than 0.2% and silicon greater Contains 0.2%.
  • the invention is based on the finding that, surprisingly, the The aforementioned hardenable steels, despite their magnetizability, also for housings by Wristwatches are suitable if the inside of the case of the Ring surrounding the movement made of diamagnetic metallic material is provided. It has been shown that through this ring the clockwork receiving part of the interior of the housing from a function and The accuracy of the clockwork impairing magnetic field can be kept free can.
  • the invention is explained in more detail below with the aid of an example of an embodiment explained.
  • the figure shows a section through a simplified representation housing according to the invention for a men's and / or women's wristwatch, together with a clockwork arranged in this housing.
  • 1 is the outer case of a men's and women's wristwatch, in which the clockwork 2 with the hands 3 and the dial 4 is housed and which on the top in the figure above through a disc or through a watch glass 5 made of sapphire glass and sealed at the bottom by a lid 6 is closed.
  • the axis of the clockwork 2 around which the hands 3 revolve is marked with A designated.
  • the watch glass 5 is suitably in a groove on the top of the Housing used and there for example by gluing or on others appropriately sealed is attached.
  • the cover 6 is screwed onto the Bottom of the housing 1 attached, sealed by a seal or O-ring 7.
  • a ring 8 enclosing the clockwork mechanism 2 is provided in the interior of the housing 1, in which the clockwork 2 is held.
  • the ring 8 has an axial height that is the same or is approximately equal to the height of the clockwork 2.
  • an intermediate cover 9 is provided which holds the ring 8 on its outer cover 6 closes facing side and via a further sealing ring 10 that of the Ring 8 formed auxiliary housing below, i.e. tight on the side facing the cover 6 concludes.
  • the intermediate cover 9 lies with its surface sides parallel to the Surface sides of the outer cover 6 and parallel to the surface sides of the Dial 4 and the watch glass 5 and thus also in planes perpendicular to the Axis A of the clock, which is determined by the axis of the hands 3. It is kept Intermediate cover 9 on the ring 8 in that this intermediate cover with its Clockwork 2 side is supported against the inner surface of the outer cover 6 with elastic deformation of the sealing ring 10, so that a vibration and rattle-free arrangement of the intermediate cover 9 is given.
  • the ring 8 With its upper end face in the figure, the ring 8 is supported on the peripheral region of the Dial 4 from, which in turn rests against a collar 11 on the Inner surface of the housing 1 is formed in that there the cross section of Interior of the housing 1 to form a in a plane perpendicular to the axis A. lying ring-shaped contact surface (collar 11) towards the top of the housing reduced.
  • the Damping ring 12 forms an elastic mounting of the ring 8 and thus the Movement 2 and protects this movement against external impacts on the watch.
  • the peculiarity of the clock shown is that the housing 1 as well the outer cover 6 from a solid material by machining a lathe, preferably on a CNC lathe made of a corrosion and acid-resistant, but nickel-free steel is made, which is hardenable and the Carbon content is over 0.1%.
  • This steel contains in addition to that Carbon content in alloy chromium, molybdenum and vanadium.
  • a steel of the group X55 CrMo 14, X65 CrMo 14, X90 CrMoV 18, X105 CrMo 17 and X 110 CrMoV 15 and in particular the steels X105 CrMo 17 and X110 CrMoV 15 are used for the production of the housing 1 and the outer cover 6 , the latter steels containing carbon, silicon, manganese, phosphorus sulfur, molybdenum and vanadium in the following proportions: X110 CrMoV 15: Carbon (C) 1.05-1.15% Silicon (Si) 1.0% Manganese (Mn) 1.0% Phosphorus (P) 0.045% Sulfur (S) 0.03% Chrome (Cr) 14.00 - 16.00% Molybdenum (Mo) 0.4 - 0.6% Vanadium (V) 0.1-0.15% X 105 CrMo 17: Carbon (C) 0.95-1.2% Silicon (Si) 1.0% Manganese (Mn) 1.0% Phosphorus (P) 0.045% Sulfur (
  • the manufacture of the housing 1 and the cover 6 takes place from the Solid material by machining, through which initially a blank will be produced. Then this blank is placed in a vacuum oven or in a Protective gas atmosphere at a temperature above 1000 ° C, preferably at a Temperature heated between about 1030 and 1060 ° C and then quenched. The blank thus hardened is then relaxed at a temperature below 200 ° C, i.e. at a temperature of about 170 - 180 ° C over a period of one to two hours.
  • the housing 1 and the cover 6, which then have a hardness of up to 63 or 65 HRC can be post-treated on the surfaces, namely for example by blasting with glass beads, high-gloss polishing, CVD-PVD coating.
  • a case-hardenable steel is also suitable for the housing 1 and / or the cover 6, which then has the following proportions of carbon, chromium, tungsten, molybdenum, vanadium, manganese and silicon: Carbon (C) 0.1 - 0.6% Silicon (Si) > 0.2% Manganese (Mn) > 0.2% Chrome (Cr) > 12% Molybdenum (Mo) > 0.2% Vanadium (V) > 0.2% Tungsten (W) > 1%
  • the housing 1 and the cover 6 can also be made with this case-hardenable steel also produce with great hardness, although the steels mentioned above X110 CrMoV 15 and X105 CrMo 17 are preferred.
  • the intermediate ring 8 is required, which consists of one of the magnetic metallic material, i.e. from one material, the existing magnetic lines repressed.
  • the ring 8 preferably consists of CuZn 40 Al2.
  • the dial 4 or this is made of the same material as the ring 8 Dial-forming disc and the intermediate cover 9 made so that the clockwork 2 completely in a housing or in a shield from the magnetic metallic material is housed.
  • the dial 4 and / or the Intermediate cover 9 can also be sufficient flat, disc-like rings that the Only partially close the upper and / or lower open side of the ring 8.
