Definitions

• the cooling unit 38 comprises a reservoir 42 of pressurized cooling fluid and a pressure reducing valve 44 capable of receiving the fluid coming from the reservoir 42 and of delivering it under a determined pressure.
• This pressure reducer is connected to a conduit 46, supplied with pressurized cooling fluid, which extends close to the reinforcement 14.
• the end of the conduit 46 comprises a nozzle 48 which is configured to spray the cooling fluid onto the surface of the valve. reinforcement 14.
• Liquid nitrogen is sprayed at a temperature of -200 ° C.
• the adhesive film 16 is cooled by thermal conduction through the reinforcement 14.
• the nitrogen application time therefore depends on the thickness and the nature of the metal reinforcement 14, as well as on the desired temperature in the adhesive film 16 to cause it to break.
• the second part that is to say the reinforcement 14 is subjected to a compressive stress in a direction D substantially perpendicular to a surface of the adhesive film 16. .
• This compressive stress is a mechanical stress corresponding to a shock exerted on the surface of the metal reinforcement 14.
• This compression wave has the advantage of being transformed into a tensile wave at the interface between the reinforcement 14 and the adhesive film 16 of the makes the difference in mechanical impedance between the reinforcement 14 and the adhesive film 16.
• the change in mechanical rigidity at the interface between two materials induces the reflection of part of the incident wave compression into a tensile wave.
• These components comprise a generator 50, converting a source of electrical energy supplying the generator into a sinusoidal electrical signal. This signal feeds a converter 52, which converts the sinusoidal electrical signal into sinusoidal vibrating waves. These vibratory waves are transmitted to an amplifier 54, which amplifies them. The amplifier 54 amplifies the vibratory waves intended for a sonotrode 56 which is able to mechanically transmit the vibratory waves. At one end of the sonotrode 56 is at least one transmission finger 58, also called an "indenter”, which receives the vibratory waves from the sonotrode 56, which is arranged in contact with the reinforcement 14 of the second part, and which is suitable for them. mechanically transmit to the reinforcement 14.
• the transmission finger or fingers 58 of the sonotrode 58 exert the mechanical stress by hammering by ultrasound, as we have seen, substantially in the direction D substantially perpendicular to a surface of the adhesive film 16 ..
• the assembly 32 of the tooling 30 enables the two stages of cooling and stressing to be carried out simultaneously. These two operations are carried out in a coverage zone C of the leading edge 20 of the blade 12 by the tooling 30, and more particularly by the fingers 58 of the sonotrode 56 immediately after passage of the nozzle 48.
• the zone C is of a length I less than the length L of the leading edge 14 of the vane 12.
• the tool 40 is therefore moved along the entire length L of the leading edge 14 of the vane 12, as illustrated FIGS. 3 and 4.
• the coverage area C first undergoes cooling by the nozzle 48 and then immediately after the mechanical stress by the transmission fingers 58.
• the immediate proximity of the fingers 58 to the nozzle 48 prevents the leading edge 20 from heating up and the cooling from losing its effectiveness.
