According to the nature of the force, the spring can be divided into tensile spring, compression spring, torsion spring and bending spring, according to the shape can be divided into disc spring, annular spring, plate spring, spiral spring, cut cone coil spring and torsion bar spring, according to the production process can be divided into cold coil spring and hot coil spring.Because of the simple manufacture of ordinary cylindrical spring, and can be made into various types according to the loading situation, the structure is simple, so the most widely used.Spring manufacturing materials should generally have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, commonly used carbon spring steel, alloy spring steel, stainless spring steel and copper alloy, nickel alloy and rubber, etc.Springs are made by cold winding and hot winding.Spring wire diameter is less than 8 mm with cold rolling method, more than 8 mm with hot rolling method.Some springs are made after strong pressure or shot peening processing, can improve the bearing capacity of the spring.
