Torsion spring is a relatively high precision spring accessories, produce torsion spring with general spring machine can not satisfy processing, torsion spring manufacturer to produce at home and abroad are usually choose spring machine produces, accuracy is relatively high, can not achieve the same point of view is not the same as the shape of the molding positioning, is a more general computer numerical control, automatic production equipment.

1, the spring is used as a force measuring element, such as force measuring device, spring in spring balance, spring load and deformation ratio is called spring stiffness, the greater the stiffness, the harder the spring.

2, the spring store and output energy as power, such as the clock spring, firearms spring.

3, spring control mechanical movement, such as the internal combustion engine valve spring, clutch control spring, etc.

4, the spring absorb vibration and impact energy, such as the car, the train under the buffer spring, vibration absorber spring in the coupling, etc.

Spring machine and electronic occupation widely used in an elastic element, the spring can form a larger elastic deformation, mechanical work or kinetic energy into deformation energy, and after unloading the spring deformation disappeared and return to its original state, deformation can be converted into mechanical work or kinetic energy.
