Abstract

The invention relates to the field of screws, and particularly discloses a screw and a machining process thereof. The surface of the screw is finished by a wear-resistant coating, and the wear-resistant coating comprises the following raw materials in parts by weight: 40-50 parts of polyethersulfone resin; 20-25 parts of 2,3,4,5-tetrafluorobenzamide; 15-20 parts of 4-chloro-2,6-difluorophenol; 8-10 parts of ceramic micro powder; 4-7 parts of butyronitrile; and 1-2 parts of a curing agent. The processing technology comprises the following steps: S1, preparing the wear-resistant coating; S2, spraying the wear-resistant coating; and S3, conducting gloss oil spraying. The polyether sulfone resin, 2,3,4,5-tetrafluorobenzamide and 4-chloro-2,6-difluorophenol are added, and the product obtained through the reaction of 2,3,4,5-tetrafluorobenzamide and 4-chloro-2,6-difluorophenol is coupled with the polyether sulfone resin, so that the tightness between structures is improved, and the wear resistance of the wear-resistant coating is improved; and besides, according to the machining process, gloss oil is sprayed to protect the screw, the friction coefficient of the surface of the screw is reduced, and therefore the wear-resisting effect of the surface of the screw is improved.

Description

technical field [0001] The application relates to the field of screws, more specifically, it relates to a screw and its processing technology. Background technique [0002] Screws refer to screws, which use the physical and mathematical principles of the oblique circular rotation and friction of objects to tighten the parts of objects step by step. They are common fasteners in various industries. In the traditional process, copper alloys with high copper content are mostly used for processing, and the wear resistance is poor, which cannot meet the needs of the rapidly developing industry and construction industry, and needs to be improved. Contents of the invention [0003] In order to improve the problem of poor wear resistance of screws, the present application provides a screw and its processing technology. [0004] In the first aspect, the present application provides a screw, adopting the following technical solution: [0005] A screw, the surface of the screw is fi...
