Abstract

The invention belongs to the technical field of precision machining, and discloses a preparation method of a gas turbine swirler, which is characterized in that the gas turbine swirler is decomposed into three parts, namely an inner ring, an outer ring and blades, then the inner ring, the outer ring and the blades are independently formed by adopting a machining method, and then the inner ring, the outer ring and the blades are connected by adopting a brazing method. In order to guarantee the brazing quality, a mounting head is machined on the heads of the blades a blade-shaped groove is correspondingly machined in the inner ring, a bayonet is correspondingly machined in the outer ring, then the outer ring, the blades and the inner ring are tensioned through an assembly tool to guarantee that brazing faces are tightly attached, spot welding is used for positioning, and the blades are conveyed into a furnace to be subjected to vacuum brazing after being completed. The roughness of the inner wall of the hollow blade is guaranteed by splitting the structure of the swirler and combining with independent machining, the tensile strength performance of brazing seams between the blades and the inner ring and the brazing seams between the blades and the outer ring is excellent under the room temperature and high temperature environment, the strength performance is better than that of base metal, the performance of the base metal cannot be lost, and the machining period is effectively shortened.

Description

technical field [0001] The invention belongs to the technical field of precision machining, and relates to a preparation method of a gas turbine cyclone. Background technique [0002] In the field of energy and electric power, the material of the gas turbine engine swirler is a deformed superalloy, the blades on the swirler are hollow blades, and there are small holes in the air film on the blades. In the prior art, production and processing are carried out by casting, but it is not easy Ensure the roughness of the inner wall in the hollow blade, so as to affect the product performance. Moreover, separate mold opening is required for single-piece production, which has a long cycle and high cost. In view of this, it is necessary to provide a preparation method that can ensure the roughness of the inner wall of the hollow blade and ensure the performance of the product. Contents of the invention [0003] The present invention provides a preparation method of a gas turbine ...
