The finger spring evolved from relying on the elastic deformation of the crossbow arm to the torsion spring using the lever principle to generate the emitting force.

Torsion spring is a relatively high precision spring accessories, the production of torsion spring with the general spring machine can not be satisfied with 1800 degrees of processing, the general production of torsion spring Dongguan spring factory choose the almighty spring machine production, the precision is relatively high, the all-round spring machine can complete different viewpoints of different shapes of the forming positioning, is a more general computer numerical control all-round machine, fully automatic production equipment.

The main functions of the all-round spring machine:

Spring is a kind of elastic element widely used in electronic work, the spring can undergo large elastic deformation when loaded, the mechanical work or kinetic energy is converted into deformation energy, and the deformation of the spring disappears and returns to its original state after unloading, and the deformation energy is converted into mechanical work or kinetic energy.

1. The spring in the all-round spring machine controls the movement of machinery, such as the valve spring in the internal combustion engine, the control spring in the clutch, etc.

2. The spring in the all-round spring machine absorbs vibration and impact energy, and the all-round spring machine is such as the buffer spring under the car and train car, the vibration absorbing spring in the coupling, etc. Slash coil spring

3. The spring in the all-round spring machine stores and outputs energy as power, such as wall clock springs, springs in firearms, etc.

4. The spring in the almighty spring machine is used as a force measuring element, such as the force tester, the spring in the spring scale, etc., the ratio of the load to the deformation of the spring is called the spring rate, the greater the stiffness, the harder the spring.

5. Modern torsion spring torsion rods are mostly made of steel with excellent elasticity, and the way has also been greatly changed, including hairsprings in mechanical watches, power springs in toy gyro guns, and torsion rods in tanks and cars. The torsion bar is small in size and has a large torque, which is very good as a shock absorber for transportation things. Shock springs
