Abstract

The object of the present invention is to provide a manufacturing process for tandem blisks, which can improve the machining accuracy of tandem blisks and reduce processing time and cost. The tandem blisk manufacturing process includes directly printing multi-level blades on the hub to form a blisk printing blank by using the additive manufacturing method of direct laser melting, and during the printing process of the tandem blisk, at least one single blisk is simultaneously printed All blades, so that all blades of at least one single disk are thickened layer by layer synchronously.

Description

technical field [0001] The invention relates to a manufacturing process of a blisk, in particular to a manufacturing process of a blisk of an aero-engine. Background technique [0002] Compared with the traditional blisk separation structure, the integral blisk integrates the blade and the hub, which has the advantages of weight reduction, stage reduction, efficiency enhancement and reliability improvement. The structure of the blisk continues to develop, from the original integrated disc to the integrated disc drum, the integrated disc shaft, and the integrated disc drum shaft, and gradually developed to a series of two or more stages of blisks connected in series in a solid state. Leaf disc. Tandem blisks are two or more stages of rotor blades radially distributed on the same hub, and blades of different stages have different blade shapes to meet aerodynamic design requirements. [0003] The overall blisk has the characteristics of poor channel opening, thin blade, compl...
