- the method according to the invention makes it possible to carry out a structural reinforcement as illustrated in FIG. 2, FIG. 2 illustrating the reinforcement 30 in its final state.
- FIG. 3 represents a block diagram illustrating the main steps of a method for producing a blade blade leading edge metal structural reinforcement 10 as illustrated in FIGS. 1 and 2.
- the first step 1 10 of FIG. embodiment method 100 is a step of manufacturing a metal insert 41 by conventional machining means known to those skilled in the art.
- the metal insert 41 is machined to substantially represent the profile and shape of the base 39 of the metal reinforcement 30 in its final state.
- flanks of the metal insert 41 are machined so as to take the intrados and extrados form of the metal reinforcement 30 and the lower face 42 of the insert 41 is machined so as to correspond to the shape of the internal profile 33 rounded to fit the rounded shape of the leading edge 16 of the dawn 10.
- the second step 120 of the production method 100 is a step of positioning, or docking, the insert 41 at the end of a preform 51 formed in a form tooling 50.
- the form tooling 50 comprises a lower portion 52 comprising the preform 51 and an upper portion 53 covering the lower portion 52 sealingly.
- the preform 51 is made to form the contour and the profile intrados and extrados desired metal reinforcement 30.
- the preform 51 has substantially the same profile as the blade on which the metal reinforcement will be assembled.
- the upper face 54 of the preform 51 is made to correspond to the complementary shape of the lower face 42 of the insert 41 which corresponds to the shape of the internal profile 33 of the reinforcement 30.
- the positioning of the insert 41 on the preform 51 is made by interlocking the lower face 42 on the upper face 54 of the preform 51 so that the assembly forms a profile equivalent to the shape of the internal part of the reinforcement metal 30.
- the third step 130 of the embodiment method 100 is a step of hot forming a flat sheet 60 placed in the shaped tooling 50 between the lower part 52 and the upper part 53 closing the tooling. waterproof way.
- the hot forming step consists of using the property of the metals which have a capacity to deform without breaking at a given temperature, such as aluminum or titanium.
- a given temperature such as aluminum or titanium.
- titanium under certain temperature conditions, for example at 940 ° C., has an elongation rate of greater than 35%.
- a hot forming process used for this step may be a superplastic forming process (SPF for Super Plastic Forming in English).
- Superplastic forming is a process for producing complex sheet metal parts with small thicknesses and in a single operation.
- the flat sheet 60 is heated to a given temperature, for example to a temperature equivalent to half the melting temperature of the material. At this temperature, the sheet 60 is deformed by the pressure of a neutral gas, for example argon, introduced inside the closed tooling 50 as shown in FIG. 5.
- a neutral gas for example argon
- the evolution of this pressure of gas, represented by arrows in FIG. 5 is controlled so that the shaping of the sheet 60b, on the insert 41 and on the preform 51, takes place in the superplastic domain which is associated with a range of deformation rate specific to each family of material.
- the prediction of the law of evolution of the forming pressure is carried out by numerical simulation so as to optimize the shaping and the cycle time of such a method.
- the temperature and pressure conditions inside the form tooling 50 are continued so as to secure the insert 41 Diffusion welding, as shown in Figure 6.
- Diffusion welding uses the atom diffusion principle to create a mechanical bond.
- the tightness of the shaped tooling 50 eliminates the risk of contamination of the parts during the diffusion bonding thereby obtaining a qualitative weld.
- This step of hot forming of the flat plate 60 may be optionally preceded by a step 170 of preparing the sheet 60 before its hot deformation.
- This preparation step 170 consists, for example, in a step of pre-machining certain areas of the sheet 60 so as to locally obtain the thicknesses approaching the final thicknesses of the flanks 35, 37 of the metal reinforcement 30 when the sheet 60 is formed. .
- the local machining of the plane sheet 60 can be carried out chemically.
- This step 170 for preparing the flat sheet 60 may also include a step of increasing the roughness of its lower face 61 which will form the inner surface of the metal reinforcement 30 in its final state.
- the roughness of the lower face 61 of the sheet 60 can also be degraded during the forming of the sheet 60 by hot forming on the preform 51, the preform 51 previously having a degraded roughness.
- the fourth step 140 of the production method 100 is a demolding step of the blade metal reinforcement 30 formed by the shaped sheet 60 and the insert 41 secured to the shaped sheet 60.
- the fineness of the flanks 35, 37 provides a certain elasticity to the assembly which allows to unmold the piece without damage.
- the fifth step 150 of the production method 100 is a finishing step and recovery of the reinforcement 30 by machining so as to obtain the thicknesses and the required profile.
- This recovery step 150 may comprise one or more sub-steps presented below, namely:
- flanks 35, 37 consisting in particular of trimming the flanks 35, 37 and the thinning of the flanks intrados and extrados by chemical machining, optionally selective if necessary;
- the method according to the invention may also comprise non-destructive testing steps of the reinforcement 30 making it possible to ensure the geometrical and metallurgical conformity of the assembly obtained.
- the non-destructive tests can be carried out by an X-ray method.
- the method according to the invention may also comprise an additional operation of increasing the roughness following demolding of the reinforcement 30 of the form tooling 50 and if the roughness is not degraded beforehand during the step of preparation 170 of the sheet 60 or during the forming step 130 by a degraded surface state of the preform 51.
- the process according to the invention has been described mainly for a titanium-based metal structural reinforcement; however, the process according to the invention is also applicable with nickel-based or steel-based materials.
- the invention has been particularly described for the realization of a reinforcement metal of a composite turbomachine blade; however, the invention is also applicable for producing a metal reinforcement of a turbomachine metal blade.
- the invention has been particularly described for producing a metal reinforcement of a turbomachine blade leading edge; however, the invention is also applicable for producing a metal reinforcement of a trailing edge of a turbomachine blade.
