Definitions
- the present invention relates to a tooling of "multi-effects" shape suitable for forming at high temperature metal parts such as for example a composite blade metal reinforcement, or metal, turbomachine.
- the tooling of "multi-effects" shape is particularly well suited to the forming of a piece of complex geometry such as a metal reinforcement of turbomachine blade leading edge.
- the field of the invention is in particular that of turbomachines and more particularly that of the fan blades, made of composite or metallic material, of a turbomachine and whose leading edge comprises a metallic structural reinforcement.
- the invention is equally applicable to the production of all pieces of complex geometrical shape and to the production of metal reinforcements intended to reinforce a leading edge or a blade trailing edge of any type of turbomachine, whether terrestrial or aeronautics, and in particular a helicopter turbine engine or an airplane turbojet engine.
- leading edge corresponds to the front part of an airfoil which faces the airflow and which divides the airflow into an intrados airflow and a flow of air. extrados air.
- the trailing edge corresponds to the posterior part of an aerodynamic profile where the intrados and extrados flows meet.
- the turbomachine blades and in particular the fan blades, undergo significant mechanical stress, particularly related to the speed of rotation, and must meet strict conditions of weight and bulk.
- One of the options considered to lighten the blades is the use of composite materials for their manufacture.
- the metal structural reinforcement protects the leading edge of the composite blade by avoiding risks of delamination, fiber breakage or damage by fiber / matrix decohesion.
- a turbomachine blade has an aerodynamic surface extending, in a first direction, between a leading edge and a trailing edge and, in a second direction substantially perpendicular to the first direction, between a foot and a dawn summit.

- unidirectional press is meant a single-effect press having only one working axis, generally the vertical axis relative to the pressing plane of the press, as opposed to double or triple-effect presses respectively comprising two or three axes. oriented in different directions.
- multi-effect is meant a deformation according to several directions occurring in several parts of the part simultaneously in opposition to a simple deformation effect resulting from a single constraint applied locally in one direction only.
- the invention it is possible to carry out a multi-effects deformation (ie in different directions simultaneously) by means of a single-effect press, inexpensive, under conditions of high temperatures, that is to say tell the temperatures necessary for the forging of the parts to realize.
- the piece is deformed and twisted in several directions in a single operation with a single-effect press and at a temperature greater than 850 ° C. 940 ° C for making a titanium reinforcement).
- the tooling according to the invention makes it possible to overcome the complex embodiment of the reinforcement by a method of milling in the mass from flats requiring large volumes of material and therefore the tool allows to reduce the quantities of raw materials necessary for the realization of such a metal reinforcement.
- the metal reinforcement of complex shape is made simply and quickly from a preform obtained from a simple metal bar and a succession of forging steps as described in particular in the patent application SNECMA FR1055066.
- the preform is then shaped three-dimensionally at high temperature in the "multi-effects" tooling by means of a single-effect press.

- the shaped screen 100 shown, by way of example, in all the figures, is a tool allowing the realization of a titanium reinforcement of turbomachine blade leading edge.
- the tooling is intended to be mounted on a single-acting press (not shown), of the forging press type, comprising a single working axis, generally the vertical axis, illustrated in FIG. 1 by the Z axis.
- the tooling can also be mounted on any type of pressure forging machine having a single working axis.
- a forging is made by placing a preform or blank between two dies, an upper die and a lower die, each having a suitable fingerprint, and then bringing the two dies closer together with each other. a pressure sufficient to deform the preform to obtain a part whose geometry corresponds to that of the impressions, the forging operation being performed with the tool mounted temperature, that is to say at a temperature above 850 ° C for producing a titanium piece and preferably a temperature of the order of 940 ° C (plus or minus 10%).
- the lower part 1 10 of the tooling comprises in particular:
- the lower matrix 1 12 is formed by:
- a second upper portion 1 12a having at its lower face locating lugs 1 18 for positioning the upper portion 1 12a in the grooves 1 19 of the lower portion 1 12b; each lug 1 18 having the shape complementary to the shape of the longitudinal grooves 1 19 of the first lower portion 1 12a.

- the lower part 1 12b of the matrix 1 12 has a flare, substantially isosceles trapezium-shaped, adapted to receive the base of the punch 1 14, also of trapezoidal shape, and adapted to center the punch 1 14 in the matrix 1 12.
- the base of the punch 1 14 is trapped between the lower part 1 12a and the upper part 1 12b of the matrix 1 12, and more precisely in a space 1 15 bordered on the one hand by the flaring of the lower part 1 12a and on the other hand by two horizontal tabs 133 projecting inwardly of the tool 1 10 in the upper part.
- these two horizontal tabs 133 of the upper portion 1 12b perform a stop function allowing only a certain vertical displacement (ie along the Z axis shown in Figure 1) of the base of the punch 1 14 in the defined space 1 15.
- the game thus created advantageously authorizes a calibrated movement between these different parts of the die 1 12, making it possible to make a punch 1 14 floating in the space 1 15 able to facilitate demolding of the piece made in the tooling 100.

- the two upper dies 121, 122 translate along the Y axis, during the displacement of the upper support 123 along the Z axis.
- the translation of the upper dies 121, 122 during the closure of the press is enabled by the complementary shape of the upper dies 121, 122 and the lower die 1 12.
- the face 131 of the lower die 1 12 in facing towards the inside of the tooling 100 forms a slope on which the upper dies 121, 122 slide during the closing of the press, generating a transversal displacement complementary to the vertical displacement according to the Z axis.
- the transverse movement of the upper dies 121, 122 is relatively guided by a guide 134, for example a free cylindrical axis, allowing the two upper dies 121, 122 to be guided during the closing and during the opening of the press.

- the spacers 141 have an outer surface 1 36 beveled forming a slope and providing a bearing surface adapted to slide on the upper dies 121, 122 during the opening of the tool 100.
- the spacers 141 go up vertically, according to the arrow referenced 161, illustrated in Figure 4, come into contact with the upper dies 121, 122 and then push the upper dies 121, 122 in a transverse direction, perpendicular to the direction of the opening of the tooling 100.
