Surface plating processing technology of high-strength fastener

Abstract

The invention relates to the technical field of fastener processing, in particular to a surface plating processing technology of a high-strength fastener. In the surface plating processing technology,the fastener is plated with zinc powder, aluminum powder and composite rare earth metal salt, and plating can effectively prevent the fastener from making contact with the external air environment, so that the fastener is prevented from being oxidized in the using process, the service life of the fastener is prolonged, and later disassembly and maintenance work of the fastener is facilitated; high-temperature gas is used in cooperation with an infrared heating lamp to dry the fastener with water in the air, so that a rust layer is prevented from being generated again after the fastener is cleaned, and deposition and attachment of the plating to the surface of the fastener are facilitated; the fastener is plated in a mechanical plating mode, so that the use cost of a traditional chemical plating can be effectively saved; and the raw materials of the mechanical plating are non-toxic, so that the environment is easy to treat, the pollution in the process can be avoided, and the annealingsoftening phenomenon is avoided after plating.

Description

technical field [0001] The invention relates to the technical field of fastener processing, in particular to a surface coating processing technology of high-strength fasteners. Background technique [0002] Fasteners are also called standard parts in the market, which is a general term for a type of mechanical parts used when two or more parts (or components) are fastened and connected into a whole. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used mechanical basic parts and are in great demand. Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a wide variety of specifications, different ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a surface coating processing technology for high-strength fasteners, which solves the problem that the existing fasteners are exposed to the air for a long time and in a humid environment. It is easy to corrode and rust, which is very inconvenient when the equipment is disassembled and repaired in the later stage
