Shenzhen hung Jie hardware spring manufacturer specializes in the production of precision springs, hardware springs, heteromorphic springs, compression springs, torsion springs, electronic smoke hardware, hardware stamping, battery chips and other hardware manufacturers. Located in the West District of the white stone building industrial district, Fuyong, Shenzhen, A4. Telephone: 0755-27380299.
The thermoforming spring is usually combined with quenching and hot forming, not only the heating temperature is slightly higher than the quenching temperature, but also the roll forming after heating, then the middle temperature tempering is carried out at the end of 350-450 degrees by the waste heat quenching, thus the tempered flexor body structure is obtained. This is a kind of deformation heat treatment process, which can effectively improve the elastic pole. Limit and fatigue life.
2, induction heating or protective atmosphere induction heating heat treatment, these processes are generally carried out on the wire before the formation of spiral springs. Some spring manufacturers put the line material heat treatment and spring production together to reduce the cost. Induction heating treatment has better strengthening effect, rapid induction heating, and help to refine grain and improve grain size. Reducing surface decarburization can give full play to the strength and toughness of materials.
