Description

Technical Field

[0001] The utility model relates to the technical field of turbine blade processing, and particularly relates to a spraying tooling for turbine blades. Background Technique

[0002] Turbine blades are important components in the turbine section of gas turbine engines. The high-speed rotating blades are responsible for sucking high-temperature and high-pressure airflows into the combustor to maintain the operation of the engine. In order to ensure stable and long-term operation in extreme environments of high temperature and high pressure, turbine blades are often forged from superalloys and cooled in different ways, such as internal air cooling, boundary layer cooling, or using thermal barrier coatings to protect the blades, etc., to ensure reliability during operation. When coating turbine blades, supporting spraying equipment is required;

[0003] The current spraying equipment has a single operation structure. When spraying, the turbine blade remains in a fixed position, and there are operation dead corners during spraying, which affects the uniformity and completion degree. Moreover, the current spraying residues are usually directly discharged, causing waste of resources and environmental pollution; for this reason, we propose a spraying tooling for turbine blades.
