Definitions
- the present invention relates to twisting equipment hot scalable used in a process for manufacturing a hollow turbomachine blade.
- One of the aims of the invention is to make it possible to carry out course of the operative flow above an operation additional shaping of parts by twisting without risk of causing buckling type ripples according to the central fiber. These ripples are generated by compression stresses induced during elongation of lateral fibers due to differences in length between the starting flat part and the obtained twisted part.
- the method of manufacturing a hollow turbomachine blade comprising an operation in accordance with the invention of setting workpiece shape using twisting equipment evolving hot according to the invention avoids the disadvantages of prior known methods and obtaining blades having geometric characteristics and improved and optimized mechanical conditions of use, guaranteeing repetitive quality while facilitating manufacturing conditions at the lowest cost.
- the method of manufacturing a hollow turbomachine blade according to the invention includes a twist operation hot-swappable, of an element intended for the manufacture of the blade by the hot twist of said alloy element TA6V type titanium, at a temperature above 700 ° C by the action of several bars animated by a movement of rotation around the twist axis and acting on shackles, previously fixed on the element, distributed according to the predetermined twist law, the distribution and number of shackles are determined so as to obtain between each yoke a linear evolution of the twist.
- Hot-swappable twist equipment for manufacture of a hollow turbine engine vane with a high rate of compression in the lower blade area is characterized by metal frame on which is vertically fixed a cylindrical oven with slots allowing the passage of bars, of a circular frame enveloping said oven, of free crowns rotating around the frame on which are fixed the bars acting on clamped shackles on the element to be twisted.
- the process for manufacturing a hollow turbine engine blade 1 comprises in accordance with the invention, an operation remarkable hot twist of the welded assembly 1 made of titanium alloy, of type TA6V consisting of hot twist of the welded assembly at a temperature between 700 and 940 °, by the action of several bars, integral with crowns driven by a frame circular with a rotational movement around the axis of the element, said bars acting on shackles flanged on the element.
- Scalable hot twist can be preceded by a bending operation including the shaping of dawn sections.
- a complementary operation of shaping by twisting and calibration may be required.
- the hot-swappable twisting equipment shown on the Figures 3 and 4 is used for carrying out the operation twisting of the hollow blade element 1 of a turbomachine in the manufacturing process according to the invention and which comes to be described.
- This hot-swappable twisting equipment consists of three separate parts: an upper part mainly intended for blocking one end of the part 1 by two jaws 3, in order to ensure immobilization in rotation and keeping in an upright position, part central unit equipped with an electric oven 2, a frame circular 6 mobile in rotation around the workpiece axis acting on free crowns 7 rotating around the frame, distributed vertically along the height of the element to be twisted and a lower part whose function main is to block the other end of element 1, to ensure during a twist a constant distance between these two ends by a tensile force supplied by means a cylinder 8 limited in its stroke by a ball bearing 9 and the transfer of part 1 from the loading station to inside the oven 2.
- Said central part composed of an electric oven circular 2 capable of a temperature range included between 700 and 940 ° C, have slots 24 intended for passage of bars 5 integral with crowns 7 whose purpose is to act on shafts 23 mounted on the part and visible in Figure 5.
- Metallic screens filled with material fibrous seal the oven to the right of the slots.
- a circular frame 6 of tubular mechanically welded construction is rotated by an electric motor 10 to variable speed by means of a ring gear 11 fixed to the upper end of the frame 6.
- the frame 6 is connected to the metal structure 12 of the equipment by connections to rollers 13, and has as many crowns 7 as necessary according to the law of evolution of the twist, said free crowns 7 rotating around the frame are connected to it by means of roller connections 14.
- Frame 6 and the crowns 7 are also fitted with drive stops 15-16, positioned to apply the twist value required on each yoke 23.
- the upper part of the oven incorporates clamping jaws 3 from one end of the part 1 and also allows the passage of the guide rod 25 connecting the jaws with the metallic structure 12.
- the upper part is mainly intended for clamping from one end of part 1 to be twisted.
- the rod 25 water-cooled ensures the guidance and connection of the jaws of clamping 3 adapted to the shape of the part 1 with the structure 12 of the equipment.
- a blocking system by corners 22 shown in more detail in Figure 5 allows position and immobilize the part 1 in a fixed position while allowing vertical translation of the part 1 of the oven 2 to the loading / unloading station located under the oven.
- a counterweight system allows the balancing of this together in order not to constrain the element to unloading.
- the lower part intended for the transfer of the loading / unloading to oven 2 also ensures clamping function of the other end of element 1 to by means of two jaws 4, free to rotate, extended by a rod 20 guided vertically by a sleeve 18 integral with a carriage 17 with vertical translation provided by the jack 19.
- the carriage 17 is equipped with a stop system at balls 9 and a jack 8 in order to apply a force of traction to element 1 so as to maintain a distance constant between jaws 3 and 4 high and low.
- the cylinder 8 also absorbs the effects of expansion of room 1 during heating.
- Shackles 23 made up of mechanically welded mechanical parts are clamped on the workpiece in positions defined by law evolution of the twist.
- a preparation table allows position them perfectly on the element.
- Figure 2 shows the determined positions A, B, C, D, E of the shafts 23 as a function of the curve evolution of the twist and these positions are reported on Figure 3.
- the electric oven 2 is maintained at a temperature greater than 700 ° for application on an alloy of TA6V type titanium, jaws 3 and 4 are in the low position ready to receive a welded assembly comprising shafts 23 distributed over the height of the welded assembly according to the law of twisting evolution, as indicated above.
- the carriage 17 transfers to oven 2 to an end position predefined stroke, then the jaws 3 are immobilized by a wedge system 22 shown in FIG. 5.
- the oven doors 21 being closed the welded assembly 1 is kept in oven 2 until it reaches the twist temperature.
- the motor 10 drives the circular frame 6 which by means of the stops 15 and 16 distributed according to the angle of twisting to be supplied in turn drives the crowns 7 of which the bars 5 by acting on the shafts 23 print at the whole welded 1 the desired twist law, then the frame 6 is driven in the opposite direction by bringing in its race the crowns 7 in the cycle start position. At this point the oven doors open and cart 17 transfers assembly 1 welded to the loading / unloading station.
