Abstract

The present application discloses a high-temperature pallet self-locking nut processing technology in the field of mechanical technology. The specific steps of the processing technology are: (1) material preparation; (2) blanking: (3) stretching forming: using a high temperature alloy plate with After the mold is fixed, the two ends of the mold are pulled for multiple times according to the shape of the product, and lubricant is added between the mold and the high-temperature alloy sheet if necessary; (4) Machining and finishing; (5) Wire cutting; (6) ) tapping; (7) Intermediate inspection; (8) Heat treatment: solution + aging treatment: solution temperature 900±10℃, time 60min, oil cooling; aging temperature 710±10℃, time 15~17h, adopt oil cooling Air cooling; (9) Sandblasting; (10) Flaw detection; (11) Surface treatment: silver plating is performed on the surface of the superalloy plate treated by the above process; (12) Inspection. The solution solves the problem of high tool consumption when producing the pallet self-locking nut in the prior art.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a process for processing high-temperature pallet self-locking nuts. Background technique [0002] The working environment of some connecting parts such as aviation, aerospace, ships and high-speed rail is often high temperature and high strength, which requires high yield strength, durability strength and creep strength, and has good processing plasticity and welding performance, which is convenient for quick installation and disassembly . [0003] At present, turning and heading processing methods are usually used in the domestic production process. Turning refers to lathe processing, which is a part of mechanical processing. Lathe processing mainly uses turning tools to turn rotating workpieces. Whether it is turning Whether it is heading processing, there are disadvantages of low processing efficiency and high tool consumption. In the actual installation and ...
