Definitions

  • the present invention relates to the field of gas turbines. It relates to a method for producing a gas turbine blade for a gas turbine as well as a tool for producing a casting core for the casting production of the blade
  • Blades of gas turbines which are attached either as blades on the rotor or as vanes on the housing surrounding the rotor, are acted upon by the hot gas coming from the combustion chamber and are exposed to thermal stresses. These blades are increasingly flows around in the course of improving the thermal efficiency with even higher turbine inlet temperatures. It is therefore inevitable that these blades must be cooled inside and / or outside by a cooling medium, in particular cooling air, preferably via the blade root is introduced into the hollow interior of the airfoil, there the blade inside convectively applied cooling method or optionally by Impact cooling cools, and is then blown into the hot gas stream, where appropriate, on the outside of the blade to accomplish a so-called film cooling.
  • the cooling medium flows through the interior of the blade usually in several serpentine-like contiguous cooling channels extending in the radial direction through the airfoil.
  • a casting core In the casting production of such a blade, a casting core must be generated, which forms the inner cavity of the blade with the cooling channels and other details during casting of the blades and keeps free.
  • a core mold composed of two mold halves is used, which are pulled apart in a certain direction during demoulding of the finished casting core (see, for example, US Pat US-A-5,716,192 ). Due to the direction in which the two mold halves must be pulled apart, there are limitations in the design of the casting core and thus the design of the interior of the later blade. These restrictions play a role, especially in complex forms of the interior, as they are used in the WO-A1-03 / 042503 are shown. In order to produce the interior of the blade, which consists of different cooling circuits, and a multiplicity of pins and turbulators, several casting cores are produced and combined with one another, which leads to a very complex production process.
  • the publication DE 101 29 975 A1 discloses a mold for the core of a gas turbine blade with interchangeable inserts to produce blades with different cavity geometries, especially in final development.
  • the invention aims to remedy this situation. It is therefore an object of the invention to propose a manufacturing method for a blade, with respect to the internal cooling while overcoming certain restrictions caused by the casting core is improved and can be produced at the same time with little extra effort. It is a further object of the invention to specify a tool for producing a casting core for the casting production of the blade.
  • the turbulators or pins extend in a direction into the interior, which is substantially perpendicular to the associated inner surface.
  • the method according to the invention for producing the blade by casting in which in a first step a core mold is provided for molding a core free of the interior of the blade, in a second step by means of the core mold of the casting core, in a third step the casting core of FIG Core mold is demolded, and in a fourth step by means of the casting core, the blade is characterized, characterized in that the provided in the first step core shape comprises two mold halves, which are pulled apart during demolding in a first direction, wherein in the mold halves in At least one mold insert is provided for the formation of the turbulators or pins, and in the third step, after the mold halves have been pulled apart in the first direction, the at least one mold insert is pulled away from the molded mold core in a second direction deviating from the first direction approx.
  • An embodiment of the method according to the invention is characterized in that the second direction is perpendicular to the inner surface belonging to the turbulators or pins.
  • a plurality of mold inserts are arranged in the mold halves, which are removed during removal from the molded cast core in different directions deviating from the first direction.
  • FIG. 1 an embodiment of a gas turbine blade according to the invention is shown in cross-section in a highly simplified representation.
  • the blade 10 has a blade profile with a leading edge 11, a trailing edge 12 and a (convex) suction side 13 and a (concave) pressure side 14.
  • the blade 10 has a wall 15 enclosing a hollow interior 16 which is used to guide cooling air is that can flow out of other provided at the trailing edge 12deluftauslässen 17 in the outer space.
  • the interior 16 may be divided by one or more web (s) 29 into several subspaces.
  • a casting core 21 (FIG. Fig. 2 ), which must be generated beforehand.
  • a core mold 23 according to the in Fig. 3 used, which is composed of two along a parting plane 25 separable mold halves 23a and 23b, which in demolding in the by the arrows in Fig. 3 indicated direction are drawn apart. Due to the predetermined direction in which the two mold halves 23a and 23b have to be pulled apart during demolding (demoulding direction), the orientation of certain elements in the interior 16 of the blade is also predefined indirectly via the casting core 21.
  • the web 29 inevitably extends in the interior 16 of the blade in Entformungsraum, because only so the mold halves 23a and 23b can be pulled with their corresponding web elements 30 from the finished casting core.
  • additional elements 18 are now arranged or formed in the interior 16 in the trailing edge region of the blade 10, which may be formed as (round) pins or (rib-like) turbulators and the Heat transfer between the cooling air flowing in the interior 16 and the wall 15 improve.
  • the direction in which the elements 18 protrude from the wall 15, starting in the interior 16, is now in an angular range, regardless of the Entformungscardi the Fig. 3 be selectable, ie the orientation of the elements 18 may differ from the orientation of the web 29.
  • the elements 18 should be perpendicular to the inner surface 19 or 20 of the wall from which they emanate, for fluidic reasons, as in Fig. 1 indicated by the right angle.
  • the casting core 21 would have to have correspondingly shaped and oriented recesses 22 (FIG. Fig. 2 ).
  • the two-part core mold 23 of Fig. 3 would have to be arranged on the mold halves 23a and 23b to form the recesses 22 corresponding form elements 26.
  • the two mold halves 23a and 23b can no longer be pulled apart in the demoulding direction without deforming or destroying the recesses 22 formed, or shearing the mold elements 26.
