Definitions

  • the invention relates to a method for the shot peening of blisk blades with a blasting material jetted onto the blade surfaces with the aid of compressed air or water and a device for carrying out the method
  • a spherical blasting medium In the shot peening of the surface of workpieces, a spherical blasting medium is thrown with the aid of compressed air at high speed against the workpiece surface to be treated. In the material surface deformed by the shot peening through a plurality of calottes, residual compressive stresses are induced so that the risk of cracking is reduced and fatigue strength is increased. Associated with this are a weight reduction, a work hardening and an increase in service life. Shot blasting is known to have long been used with engine components and here also for blading blades.
  • Gas turbine rotors and in particular the rotors of gas turbine engine compressors, are designed with a blading integrally formed on the annular outer periphery of a disk for reliability, weight saving, power enhancement, and durability.
  • Such components are referred to as blisks, the term blisk being a shorthand of the English language term "blade integrated disk".
  • the production of blisks is known to be done by welding, in particular friction welding, separately manufactured blades with the peripheral annular surface of the preferably forged disc or by a proceeding from the outer annular surface of the disc material removal by means of cutting or chemical processes. After forming and finishing the blades, and after the blisk is heat-treated, the blisk blade surfaces can be shot-peened to increase their strength and life by introducing compressive residual stresses into the surface layer.
  • the individual blades are arranged in hermetically sealed chambers containing a shot blasting medium set in motion by ultrasound. This method is particularly disadvantageous because of the high cost of sheathing the blades.
  • the invention has for its object to provide a method for shot peening the blades of Blisks or Blisktrommeln that ensures a low cost and without affecting the blade shape uniform and high surface hardening of the blades, and to provide a device for performing the method.
  • the essence of the invention lies in the separate processing of each individual blisk with simultaneously and immediately opposite and with identical beam intensity and substantially perpendicular to the suction side and the pressure side impinging shot peening, which are guided in adjacent processing paths on the two side surfaces of the respective Bliskschaufel.
  • the beam intensity identical on both blade sides is achieved in that the distance between the jet exit plane and the irradiated surface on both blade sides is substantially the same.
  • the strength of the blisk blades is increased, so that increases in the fatigue strength and elimination of tensile stresses on the component surface are possible.
  • the risk of cracking is minimized, so that ultimately the life is increased. Due to the uniform, high beam intensity in all surface areas, small-diameter blasting balls can be used, so that even small radii in the transition area to the annulus are detected and hardened by shot blasting.
  • the shot peening (shot blast nozzles) have a rectangular cross-sectional shape and are guided in the longitudinal direction of the blisk blades in adjacent, preferably overlapping processing paths over the two blade surfaces.
  • the overlapping of the machining paths compensates for a lower beam intensity and spherical beam coverage in the edge region of the spherical jet.
  • the device according to the invention for carrying out the method comprises a double-jet nozzle unit arranged at a movement unit with two elongated jet blast nozzles arranged at a distance and correspondingly adjustable with respect to the respective blade design, which have nozzle openings of the same shape and size arranged laterally and pointing towards each other at the same height.
  • the double-jet nozzle unit can be moved with the jet nozzles arranged on both sides of the blade during processing in the longitudinal direction and in the transverse direction of the individual blisk blades and can also be pivoted about an X-axis and a Y-axis, so that the Shot blasting the scoop surfaces completely capture and also the curved and twisted shape of the blisk blades can follow at a constant distance and all blade areas are treated with substantially the same beam intensity.
  • the blasting material nozzles and the nozzle openings have a rectangular cross-section or a rectangular Gutaustrittsquerites, so that the blade surfaces can be uniformly shot-peened along wide, planar machining paths.
  • the nozzle openings are delimited at the free end-side end of the blasting material nozzles by a plane baffle plate arranged at an obtuse angle to the flow direction.
  • the blasting balls are deflected outwardly in the direction of the blade surface at an angle that is equal to or more than 90 °, so that the blade surfaces are predominantly perpendicularly struck by the blasting balls, but also the transition region of the blisk blade to the annulus of the shot peening is detected.
  • the length of the blasting material nozzles is selected so that the blasting material emerging from the nozzle openings also detects the transition region.
  • Blisktrommel 3 comprises a moving unit 4, with a mounted on a nozzle holder 5 double jet nozzle unit 6 according to the arrows A and B in the vertical direction and in the horizontal direction (see Fig. 1 ) can be moved and pivoted according to the arrow X about a horizontal axis and according to the arrow Y about a vertical axis (see Fig. 2 ) can be.
  • the double-jet nozzle unit 6 comprises two blasting-material nozzles 7, each designed as flat, rectangular and elongated hollow bodies, which are arranged with their broad sides spaced apart and substantially parallel to one another.
  • the distance between the two Strahlgutdüsen 7 is adjustable and is adjusted depending on the blade thickness-shape and distance so that the Strahlgutaustragsdüsen 7 do not contact the machined Bliskschaufeln 1 or these adjacent Bliskschaufeln during Kugelstrahlverfestigens.
  • the length of the Strahlgutdüsen 7 is greater than the maximum height of the machined Bliskschaufeln 1.
  • the two Strahlgutdüsen 7 have at the front free end in each case a laterally arranged, substantially over the entire width b reaching - rectangular -
  • Nozzle opening 8 on.
  • the closed front end of the nozzle opening 8 and the Strahlgutdüse 7 is formed by an oblique, approximately at an angle of 45 ° extending baffle plate 9, at which about the Strahlgutdüse 7 supplied Strahlgutstrom or the Strahlgutkugeln 10 deflected by about 90 ° or greater and thus approximately perpendicular to the longitudinal extent of the Strahlgutdüsen 7 and to the flow direction in the Strahlgutdüsen 7 are discharged via the nozzle opening 8.
  • the nozzle openings 8 of the two Strahlgutaustragsdüsen 7 are directed towards each other and arranged exactly opposite each other.
  • the respective Strahlgutaustragsdüse 7 is connected to a Strahlgut arrangements Georgia 11, which in turn is connected to a Strahlgutzu operations effet 12 having a substantially circular cross-section.
  • the inner cross section of the Strahlgut executions Georgia 11 is formed so that the over the Strahlgutzu operationss effet 12 by means of compressed air or water supplied jet medium circular cross section of Strahlgutstroms gradually, that is without energy losses and turbulence of Strahlgutstroms and simultaneously increasing the speed of the solidification balls, in a rectangular inner cross section the Strahlgutaustragsdüsen 7 corresponding cross section is transferred.
  • the double-jet nozzle unit 6 is moved in a plurality of overlapping paths in the longitudinal direction of the blisk blade 1 to be individually processed by means of the movement unit 5.
  • the overlapping of the processing paths is required because the emerging at the edges of the nozzle opening 8 blasting material is slightly lower than in the Center.
  • the Bliskschaufel 1 is located during processing centrally between the two set at a distance corresponding to the cross-sectional profile of the respective Bliskschaufel Strahlgutdüsen 7, so that on the suction side and the pressure side of the Bliskschaufel 1 each of the opposite surface areas with a due to the central arrangement on both sides the same strong ball jet are acted upon and thus no deformation of the Bliskschaufeln 1 by unilateral or different strength in the action of the shot peening is recorded.
  • the double-jet nozzle unit 6 When the double-jet nozzle unit 6 is moved along the machining paths, the double-jet nozzle unit 6 is pivoted in accordance with the arrows X and / or Y so that the blasting material exit plane follows the opposing nozzle openings 8 of the rotated blade shape and is aligned substantially parallel and equidistant from the blade surface.
  • the blasting material balls can have a comparatively small diameter, so that even areas with small radii, for example in the transition region between the lateral blade surfaces and the annulus, can be processed with the radiation medium and hardened by shot blasting. Due to the individual processing of the blisk blades, wherein the blasting shot with small diameter substantially perpendicular and impinge with the same strength only on the side surfaces, in particular a deformation of the filigree, particularly easily deformable blade edges is prevented. With the method described above, each individual Bliskschaufel on the pressure side and the suction side is processed with the same beam intensity and fully shot-peened solid.
