Abstract

The invention aims at providing a series blisk manufacturing technology capable of improving the machining precision of a series blisk, shortening the machining time and reducing the machining cost. The series blisk manufacturing technology comprises the steps that a laser direct melting additive manufacturing method is utilized for directly printing multi-level blades on a hub, and a blisk printing blank is formed; and in the series blisk printing process, all blades of at least one single disc are synchronously printed, and all the blades of at least one single disc are synchronously thickened layer by layer.

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 hub design, which has the advantages of weight reduction, level reduction, efficiency increase and reliability improvement. The structure of the overall blisk has been continuously developed, from the initial one-piece disc to one-piece disc-drum, one-piece disc shaft, one-piece disc-drum shaft, and gradually developed to a tandem-type whole in which two or more stages of blisks are connected in solid state. Leaf disk. The tandem blisk has two or more stages of rotor blades radially distributed on the same hub, and the blades of different stages have different blade shapes to meet the aerodynamic design requirements. [0003] The overall blisk has the characteristics of poor channel opening,...
