Abstract

The application discloses a high temperature support plate self-locking nut processing technology in the mechanical technology field. The high temperature support plate self-locking nut processing technology includes concrete steps: (1) preparing material; (2) blanking; (3) stretching for forming: fixing a mold for high temperature alloy sheet material, pulling two ends of the mold according to shape of a product for repeated stretch forming, and adding lubricant between the mold and the high temperature alloy sheet material when necessary; (4) performing machining for fine trimming; (5) performing linear cutting; (6) performing thread tapping; (7) performing in-process inspection; (8) performing heat treatment: performing solid dissolution and aging treatment, wherein in solid dissolution, setting solid dissolution temperature at 900+/-10DEG C, keeping solid dissolution time for 60min, and then adopting oil cooling; in aging treatment, setting aging temperature at 710+/-10DEG C, keeping aging time for 15-17h, and then adopting air cooling; (9) blasting sand; (10) detecting fault; (11) performing surface treatment: plating silver on the surface of the high temperature alloy sheet material after being processed through the above steps; (12) inspecting. The high temperature support plate self-locking nut processing technology solves the problem that cutter consumption is high in production of support plate self-locking nuts 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 ...
