A chain production process

Abstract

The invention discloses a chain production process, including: a. heat treatment: in heat treatment equipment, various auxiliary media are used at high temperature to improve the organizational structure of parts and improve the performance of various items; b. carburizing: put the parts in Heat and keep warm in the heat treatment equipment, and then pass through the carbon-containing medium to infiltrate the carbon into the surface of the parts to improve the hardness and wear resistance of the chain; c, quenching; d, tempering; e, blackening; f, bluening; g , Shot peening: Spray the steel shot with the required diameter on the surface of the part according to the need to form uniform small pits to improve the surface fatigue strength of the chain; h, Phosphating: Immerse the part in a phosphating solution at a certain temperature Inside, a phosphating layer is formed on the surface of the parts, which can make the surface of the parts black or gray, improve the appearance of the chain and achieve the purpose of anticorrosion; i. Oiling: After putting the chain into the oil immersion equipment, coat the chain surface Apply oil to prevent the chain from rusting and make the chain more shiny; j. Inspection and storage.

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
