The spring steel of mechanical spring must have higher elastic limit and higher yield ratio to avoid permanent deformation of spring under high load. At the same time, good hardenability and low decarburization sensitivity are required to greatly reduce the elastic limit; good surface quality, easy processing and molding, and good heat treatment processability under hot and cold conditions.
Springs formed under heating conditions (usually more than 10 mm in diameter or thickness)
Heat treatment process for thermoforming mechanical springs - most springs formed by this method are combined with thermoforming and heat treatment, while coil springs are mostly heat treated after thermoforming. The heat treatment method of the spring steel is quenching and tempering at medium temperature. The microstructure of the steel is tempered magnesite. This kind of structure has higher elastic limit, yield limit and certain toughness.
The spring is formed in cold state (diameter or thickness is usually less than 10 mm)
Heat treatment of cold-formed mechanical springs - for springs made of cold-rolled steel, steel or cold drawn steel, the material is reinforced by cold-plastic deformation to achieve the required properties of the spring. Therefore, after forming the spring, it is only necessary to maintain the stress relief treatment in the range of about 250 ℃ for about 30 minutes, so as to eliminate the internal stress generated by the cold formed spring and form the spring.
The above is Zhejiang spring manufacturer In the production of spring, spring forming process, high-tech production technology, production of high-quality spring, for more demand to provide wholesale spring, spring price is reasonable, if you need to know more, please contact Zhejiang Yuanhua spring manufacturer!
