Description

technical field

[0001] The invention relates to the technical field of nut manufacturing, in particular to a nut manufacturing process. Background technique

[0002] There are many types of nuts, including typical hexagonal nuts, captive nuts, channel nuts, fulcrum nuts, lock nuts, movable joint nuts, outer casing nuts, small round nuts, connecting nuts, hexagonal thin nuts, support plate nuts, and double-ear self-supporting nuts. Lock nuts, etc.; play the role of connecting parts on the aero-engine, mainly responsible for the connection of pipeline parts, sealing parts and the connection of various parts, the quality of its processing is good or bad for the transmission, fastening and sealing of parts has a direct impact.

[0003] A kind of manufacturing process disclosed as Chinese Patent No. CN107931574A comprises the following steps: the first step: melting copper and iron, at first copper is put into melting furnace, then iron is put into another melting furnace, and m...

Embodiment Construction

[0024] The following descriptions are only preferred implementations of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions under the idea of ​​the present invention shall belong to the scope of protection of the present invention. At the same time, it should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0025] A kind of manufacturing process of nut, comprises steps as follows:

[0026] A: Selection of raw materials: Select steel wire after carburizing. The carbon content in the steel wire is 0.45-0.55%, the aluminum content is 0.6-0.75%, the silicon content is less than 0.2%, and the rest is iron, and it is coiled into a coil. Carbon steel wire can make the nut harder;

[0027] B: Annealing: Send the coil into the annealing furnace for anneali...
