Problems solved by technology

[0002] At present, the material of the baffle parts used in the engine is GH4169 alloy. The strengthening elements in the GH4169 alloy account for 4.5% of the total elements. The new baffle parts use the GH738 alloy material, and the strengthening elements account for 8.6% of the total elements, nearly doubled. , the difficulty has increased a lot, and the original forming technology of baffle parts can no longer meet the forming requirements of new baffle parts.

Abstract

A high-deformation-resistance high-temperature alloy baffle forming process is characterized by comprising winding shaping, heat treatment shaping and a finish machining process of complex shapes of baffle tips, wherein the adopted material is GH738 alloy, a wire is wound around a forming core rod, the diameter of a winding fixture is 350-420 millimeters, at the time of winding, the rotating speed of a lathe is adjusted to be 10-30 revolutions per minute, the distance between a middle support plate and the fixture is adjusted manually, after the wire is wound, a part blank is bounced off from the fixture, and then solution treatment, aging treatment, linear cutting and coping chamfering are carried out. The high-deformation-resistance high-temperature alloy baffle forming process has the advantages that the winding shaping, the heat treatment shaping and the finish machining process of the complex shapes of the baffle tips completely meet the design requirements of parts, can meet the using performance requirements of the GH738 alloy parts, and can be widely used for manufacture of various large-size high-deformation-resistance baffle type parts of engines.
