Chain production process

Abstract

The invention discloses a chain production process. The chain production process includes the steps that a, heat treatment is carried out, in heat treatment equipment, various auxiliary media are adopted under the high temperature to improve the organization structure of parts and improve the performance of various articles; b, carburization is carried out, the parts are placed in the heat treatment equipment to be heated and kept warm, and then carbon containing media are introduced to infiltrate the carbon into the surfaces of the parts so as to improve the hardness and abrasion resistance of a chain; c, quenching is conducted; d, tempering is conducted; e, blacking is conducted; f, bluing is conducted; g, shot blasting is conducted, and according to the requirements, steel shots with the required diameters are sprayed on the surfaces of the parts to form uniform small pits, so that the surface fatigue strength of the chain is improved; h, phosphorization is conducted, the parts areimmersed in phosphating liquid with a certain temperature to form a phosphating layer on the surface of each part, the surface colors of the parts can appear black or gray, the beauty of the chain isimproved, and the purpose of corrosion resistance is achieved at the same time; i, oiling is conducted, after the chain is put into oil immersion equipment, the oil is applied to the surface of the chain to prevent rust and the chain is more shiny; and j, inspection and warehousing are conducted.

Description

technical field [0001] The invention belongs to the technical field of chain processing, and in particular relates to a chain production process. Background technique [0002] Chains are basically labor-intensive products, and many developed countries have turned to developing countries for production, which has brought new opportunities for my country's chains to expand exports. [0003] The chain manufacturing capacity is the decisive factor of the chain manufacturing industry, and the core of the chain manufacturing strength is the degree of craftsmanship of the chain manufacturing. The degree of chain manufacturing technology depends largely on the professional degree of chain consumption. The degree of equipment strength directly affects the production efficiency of the chain manufacturing company, the quality of the product, and the economic benefits. [0004] In order to prolong the service life of the chain, oil is usually applied on the surface of the chain to pro...

Problems solved by technology

[0004] In order to prolong the service life of the chain, oil is usually applied on the surface of the chain to protect the chain and make the chain more shiny. The existing oiling method generally adopts the oil immersion method, that is, directly put the chain into the oil Then take out the chain, the joints of the chain links are in a bonded state, even if the chain is placed in the oil, the joints of the chain links still cannot contact with the oil, resulting in a dead angle of oiling, and the joints of the chain links cannot be contacted. Protected and easy to oxidize, which affects the service life of the chain
