Spring according to the nature of force, shape can be divided into several categories
According to the force nature of the spring, the spring can be divided into a tension spring, a compression spring, a torsion spring and a bending spring. The shape can be divided into a disc spring, an annular spring, a plate spring, a coil spring, a truncated cone vortex spring and a torsion bar spring. Wait. Ordinary cylindrical springs are widely used due to their simplicity of manufacture, their ability to be manufactured in various types depending on the loading conditions, and their simple structure. Spring manufacturing materials generally should 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 alloys, nickel alloys and rubber Wait. Springs are manufactured by the cold roll method and the hot roll method. The cold coil method with a spring wire diameter of less than 8 mm and the hot coil method with a diameter of more than 8 mm. Some springs are also subjected to strong pressure or shot peening after they are made, which can increase the bearing capacity of the spring.
The spring is a kind of elastic component widely used in the mechanical and electronic industries. When the spring is loaded, it can produce a large elastic deformation, transform mechanical or kinetic energy into deformation energy, and after unloading, the deformation of the spring disappears and returns to its original state. Deformation can be converted into mechanical or kinetic energy.
