The meaning of the spring

Spring is a kind of mechanical parts use flexibility to work.Usually made from spring steel.Used to control the movement of the parts, moderate impact or vibration, energy savings, the size of the measuring force, etc., widely used in machinery, instrument.The sort of spring is complex, the shape can be divided into the disc spring, circular spring, leaf spring, coil spring, truncated cone vortex coil spring and torsion bar spring, etc.According to the mechanical properties are divided into compression spring, torsion spring, profiled spring, etc.According to the production process can be divided into cold coil spring and hot coil spring.Ordinary cylindrical spring because of its simple manufacture, and can be made into various types according to the load situation, simple structure, is the most widely used.Spring manufacturing materials in general should have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, such as the commonly used carbon spring steel, alloy spring steel, stainless spring steel and copper alloy, nickel alloy and rubber, etc.Spring manufacturing methods of cold rolled and hot rolled method.Spring wire diameter less than 8 mm with cold roll method, generally greater than 8 mm with hot volume method.Some spring after made to crush or shot peening treatment, can improve the bearing capacity of the spring.
