Abstract

The invention provides a positioning structure for a turbine blade blank, which can be used for solving the problems of non-uniform material flow and low material utilization ratio of a blank in a die forging process due to the absence of an effective positioning device for die forging of the conventional blank, can be used for effectively solving the problem of short service life caused by wear of a die, and contributes to lowering the production energy consumption and increasing the production efficiency. The positioning structure is characterized by comprising a forging die, wherein a material carrying table is arranged on the end part of the outer side of a leaf-crown-shaped cavity of a lower die forging module; a positioning lug is arranged on the top of a blank to be processed; the blank is arranged in the die cavity of the forging die; and the positioning lug of the blank is limited by using the material carrying table.

Description

Technical field [0001] The invention relates to the technical field of die forging of turbine blades, in particular to the positioning structure of a turbine blade blank. Background technique [0002] The blank is a transition between the bar and the forging, and the placement of the blank in the mold cavity has a greater impact on the final forming result of the forging. In actual production, the size difference of the same batch of blanks is often encountered but the forging The size of the later forgings is quite different, which is often determined by the positioning of the blank in the mold cavity. For blade forgings, especially for moving blades, there is usually no corresponding positioning measures in the design of the blank and die, which results in uneven material flow during the forging process, especially for the large twist angle of the blade crown and blade root. Even if damping is added to the easy-flow side of the mold cavity, the blank positioning effect cannot ...
