Definitions
- the present invention relates to a method for shaping a barrel spring for a mechanism driven by a motor spring, especially for a timepiece, formed of a metal glass material.
- the initial alloy strip is formed into a barrel spring in two steps:
- the band is wound on itself to form a tight spiral (elastic deformation) and then treated in an oven to fix this shape.
- This heat treatment is also essential for the mechanical properties because it makes it possible to increase the elastic limit of the material, by a modification of its crystalline structure (hardening by precipitation);
- the spiral spring is estrapade, so plastic deformed cold to take its final form. This also makes it possible to increase the level of constraint available.
- the mechanical properties of the alloy and the final shape are the result of the combination of these two steps. A single heat treatment would not achieve the desired mechanical properties for traditional alloys.
- the fixing of crystalline metal alloys involves a relatively long treatment time (several hours) at a temperature high enough to induce the desired modification of the crystalline structure.
- the object of the present invention is to overcome, at least in part, the aforementioned drawbacks.
- the subject of the present invention is a method for shaping the mainspring according to claim 1.
- FIG. 1 is a plan view of the spring loaded in the barrel
- Figure 2 is a plan view of the spring disarmed in the barrel
- Figure 3 is a plan view of the spring in its free state
- Figure 4 is an armature-disarming diagram of a metal glass barrel spring.
- the ribbons intended to form the barrel springs are made by the technique of quenching on a wheel (or Planar Flow Casting) which is a technique for producing metal ribbons by rapid cooling. A jet of molten metal is propelled on a cold wheel that rotates at high speed. The speed of the wheel, the width of the injection slot, the injection pressure are all parameters that will define the width and thickness of the ribbon produced. Other techniques for producing ribbons can also be used, such as the Twin RoIl Casting.
- the alloy used is Ni 53 Nb 2 OZrgTiioC ⁇ 6 Cu 3 in this example. From 10 to 20 g of alloy are placed in a distribution nozzle heated between 1050 and 1150 ° C. The slot width of the nozzle is between 0.2 and 0.8 mm. The distance between the nozzle and the wheel is between 0.1 and 0.3mm. The wheel on which the molten alloy is deposited is a copper alloy wheel and driven at a speed of 5 to 20m / s. The pressure exerted to bring the molten alloy out through the nozzle is between 10 and 50 kPa. Only a good combination of these parameters made it possible to form ribbons with a thickness greater than 50 ⁇ m, typically of> 50 to 150 ⁇ m and a length of more than one meter.
- the barrel spring releases its energy as it moves from the armed state to the disarmed state.
- the goal is to calculate the shape that the spring must have in its free state so that each section is subjected to the maximum bending moment in its armed state.
- Figures 1 to 3 below respectively describe the three configurations of the barrel spring namely armed, disarmed and free.
- the spring in its armed state is considered a spiral with the turns tight against each other.
- any point on the curvilinear abscissa can be written by: r n ⁇ r bonde + ne (2) r n : Radius in the armed state of the nth turn [mm] rbonde: Radius of the barrel plug [ mm] n: Number of turns of armor e: Thickness of the ribbon [mm] Moreover the length of the curvilinear abscissa of each turn is given by:
- the metallic glass ribbon is obtained by rapid solidification of the liquid metal on a copper wheel or alloy with high thermal conductivity rotating at high speed.
- a minimum critical cooling rate is required to vitrify the liquid metal. If the cooling is too slow, the metal solidifies by crystallization and loses its mechanical properties. It is important for a given thickness to guarantee the maximum cooling rate. The higher it is, the less the atoms will have time to relax and the higher the concentration of free volume will be important. The ductility of the ribbon is then improved.
- Plastic deformation of metal glasses below about 0.7 x glass transition temperature T g [K] is heterogeneously through the initiation and then the propagation of slip bands.
- the free volumes act as sites of germination of the sliding bands and the more their number is high, the less the deformation is localized and the more the deformation before rupture is important.
- the Planar Flow Casting stage is therefore crucial for the mechanical and thermodynamic properties of the ribbon.
- T 9 -IOOK glass transition temperature
- T 9 glass transition temperature
- T 9 glass transition temperature
- T 9 glass transition temperature
- Tg viscosity at Tg
- T g thermal activation will allow the diffusion of free volumes and atoms within the material.
- the atoms will locally form denser domains, close to a crystalline structure at the expense of free volumes, which will be annihilated.
- This phenomenon is called relaxation.
- the decrease in free volume is accompanied by an increase in Young's modulus and a decrease in the subsequent ductility.
- the relaxation phenomenon can be likened to annealing.
- the thermal agitation the relaxation is accelerated and causes a drastic embrittlement of the glass by annihilation of the free volume. If the treatment time is too long, the amorphous material will crystallize and thus lose its exceptional properties. Hot forming is therefore a balance between sufficient relaxation to retain the desired shape and as little ductility as possible.
- the ribbons produced by the Planar Flow Casting (PFC) technique have a width of several millimeters and a thickness of between 40 and 150 ⁇ m.
- the wire width electroerosion technique was used to machine ribbons with the typical width and length of a mainspring. A sidewall grinding was performed, after which the spring was shaped from the theoretical form as previously calculated.
- the spring in its setting was then introduced into a heated oven around T 9 (590 0 C) for a period of 3 to 5 minutes, depending on the setting used.
- FIG. 4 shows the variation of torque as a function of the number of revolutions obtained with the spring calculated and shaped according to the method described in this document.
- This armor - disarming curve is quite characteristic of the behavior of a mainspring.
- the torque, the number of turns of development and the overall yield are fully satisfactory given the dimensions of the ribbon.
