Description
Technical Field
The invention belongs to the technical field of manufacturing of engine air sealing rings, and particularly relates to a manufacturing device of an air sealing ring with a high-temperature alloy steel belt wrapped braided rope structure.
Background
The high-temperature alloy steel belt wraps the braided rope structure gas sealing ring, is installed between a turbine outer ring of the turbine guider of the engine and the blades of the guider, and is used for sealing gas and preventing high-temperature gas from being mixed with a cooling gas channel.
The high-temperature alloy steel belt wrapped braided rope structure air sealing ring used for the engine is manufactured by wrapping a 6J20 braided rope by using a high-temperature alloy steel belt made of GH3030, and then forming slender cylindrical strips with various diameters and lengths, wherein the cylindrical surface is required to be smooth and free of bulge, and the joints of the cylindrical strips are required to be straight and free of distortion. The manufacturing method can theoretically be formed by cold stamping through a cold stamping die, but because the diameter of the gas seal ring used by the engine is small and the length of the gas seal ring is long (such as the gas seal ring with the diameter phi of 2.4mm multiplied by the length 378 mm), if the gas seal ring is processed by cold stamping through the stamping die, a female die and a male die with the arc radius of R1.2mm and the length of more than 378mm need to be designed, the processing difficulty of the die is very high, particularly, the groove of the female die is long and thin, the requirement on the straightness tolerance is very high, and the processing cannot be finished through conventional processing equipment and tools. In addition, a method for cold-drawing and forming a steel strip by adopting a common drawing die on a lathe is also provided, but because the steel strip made of a high-temperature alloy material has high tensile strength (about 2 times of common carbon steel and 1.27 times of austenitic stainless steel), severe cold hardening and large bending deformation resistance, the method is applied to the gas seal ring for processing the steel strip made of the high-temperature alloy material, bulging is easy to generate at the seam of the steel strip due to incomplete deformation in one-time drawing deformation, and the original bulging cannot be completely eliminated due to severe cold hardening of the high-temperature alloy material in multiple times of drawing, and the seam of the steel strip can be distorted along the circumference in the length direction of the gas seal ring, so that the quality requirement of the gas seal ring of an engine is not met, and therefore research and design of a manufacturing device suitable for wrapping the braided rope structure gas seal ring by the high-temperature alloy steel strip are needed to solve the problem.
