2.AFR Precision Technology Co.,Ltd is specialized in Industry and agriculture,Hardware tools,Spring since established in 10 years ago.So far,our company has established its branch companies in major cities throughout the country.Formed in Room 816, RongChao Financial Center, No 52, RuYi Road, LongCheng Street, LongGang District, ShenZhen,China.,Longgang District,Shenzhen City,Guangdong Province,China as the center, the radiation sales system and service network.Details:According to the force nature, the spring can be divided into tensile spring, compression spring, torsion spring and bending spring. According to the shape, it can be divided into disc spring, ring spring, plate spring, spiral spring, cone scroll spring and torsion bar spring, and can be divided into cold coil spring and hot coil spring according to the process of production. The ordinary cylindrical spring is simple in application and can be made into various types according to loading conditions. In general, the material of the spring should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, such as carbon spring steel, alloy spring steel, stainless steel spring steel, copper alloy, nickel alloy and rubber. The methods of producing spring are cold roll and hot coil. The spring coil diameter less than 8 mm is generally used in cold coil method, and the coil method is larger than 8 mm. Some springs are pressed or shot peening after they are made, which can improve the bearing capacity of the springs.A compressed spring (compression spring) is a spiral spring that bears the direction of pressure. The cross section of the material is mostly circular and is also made of rectangular and multi strand steel. T |
