Definitions

  • the invention relates to a method for producing turbo rotors, in which prefabricated blades are connected to the rotor body by hot powder pressing.
  • the object is achieved in an excellent manner by the method according to the invention, in that the capsule formation means that the highest pressures can be transferred to the compact and at the same time the desired high dimensional accuracy is guaranteed.
  • An additional advantage of the method according to the invention lies in the fact that the prefabricated blades can be made of a different material than the hub body of the rotor, which may result in more favorable operating properties of the finished rotor.
  • the capsule shown in longitudinal section in FIG. 1 for the hot isostatic pressing essentially consists of a ceramic core 1, which has the negative contour of a radial turbine wheel with a hub area 12 and blade matrices 11, the upper side of the ceramic core being open.
  • the ceramic core 1 is enclosed by a sheet metal outer skin 2, which rests on the base and the side surfaces of the ceramic core 1, while it maintains a distance A from the top of the ceramic core, which is necessary because a volume reduction takes place during the pressing process.
  • the distance A is precisely matched to the compression to be expected.
  • On the upper side of the sheet metal outer skin 2 there is a filling opening 3 in the middle for the powdery material of the compact, which is closed pressure-tight before the pressing process.
  • the blade matrices 11 of the ceramic core 1 are shown as a straight, flat column, which accordingly requires the insertion of straight, flat blades.
  • straight, flat column curved columns can also be provided, in which correspondingly curved, prefabricated blades can be inserted.
  • the partial section according to FIG. 3 serves to illustrate the connection of prefabricated sheet metal blades, one of which is shown in cross section and is provided with the reference number 21, with the hub 12 to be produced from powder.
  • the blade 21 is tapered at its root 20.
