Torsion spring is a relatively high precision spring accessories, production of torsion spring with the usual spring machine processing can not meet the 1800 degrees, usually producing torsion spring are spring machine production at home and abroad, the precision 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.

Spring machine and widely used in the electronic industry spring machine and an elastic element, the spring under load can cause a greater elastic deformation, the mechanical work or kinetic energy into deformation energy, and the spring after unloading the deformation disappeared and restore the original state, the deformation can be converted to mechanical work or kinetic energy.

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

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

3, the spring store and output energy as power, such as clockwork spring, firearms spring.

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