Problems solved by technology

[0003] Aiming at the problems existing in the prior art, the present invention provides a method for combining and positioning general-purpose single-crystal turbine working blade modules. Single crystal turbine working blade modules of different heights ensure the verticality during the combination process of single crystal blade modules, so that a better crystal orientation can be obtained during the solidification process of single crystal blades, reducing the labor intensity of workers and improving production efficiency

Abstract

The invention belongs to the technical field of precision casting, and particularly relates to a method for combined locating of general single crystal turbine working blade mold sets. A middle column tube, a bottom disc and an upper disc are located through locating pins and a locating groove, the positions of the bottoms and tops of blade wax pieces in the mold sets are fixed, and therefore perpendicularity of the single crystal blade mold sets in the combining process is effectively guaranteed, and good crystal orientation is obtained in the single crystal blade solidification process. The middle column tube can be adjusted and located according to the height of different blade mold sets, and the requirement for combining the single crystal blade mold sets with different heights can be met.

Description

technical field [0001] The invention belongs to the technical field of precision casting, and in particular relates to a combined positioning method for a general single-crystal turbine working blade module. Background technique [0002] The crystal orientation of a single crystal blade has an important influence on its mechanical properties, and the crystal orientation of a single crystal is largely affected by the combined module. During the assembly process of single crystal blade modules, the chassis, center column tube, upper disk and blade wax parts are mainly completed manually, and the verticality of single crystal blade wax parts cannot be guaranteed; if combined tooling is used to ensure its verticality, different single crystal The combined heights of the blade modules are different, so different combined tooling is required, which leads to an increase in the manufacturing cost of the tooling and low work efficiency. Contents of the invention [0003] Aiming at...
