Spring is a kind of elastic element widely used in modern industry and electronic industry, spring can produce large elastic deformation when loaded, and convert mechanical kinetic energy into performance, and after unloading, the deformation of the spring disappears and returns to its original state, while converting the deformation energy into mechanical kinetic energy. The ratio of the load to the deformation of the spring is called the spring rate, and the greater the stiffness, the harder the spring.

The role of the spring

1: Cushioning and vibration damping. Such as vibration damping springs under the box of cars and trains, buffer springs of various buffers, etc.;

2: Control the movement of the mechanism. Such as valve springs in internal combustion engines, control springs in clutches, etc.;

3: Store and output energy. Such as clock springs, bolt springs, etc.;

4: Measure the magnitude of the force. Such as spring scales, springs in dynamometers, etc.;

Spring in the work often subject to alternating and impact load, and require large deformation, Dongguan spring factory spring material should have high tensile strength, elastic limit and fatigue strength. In the process, it must have a certain hardenability, not easy to decarburize, and the surface quality is good.
