The practical application of springs in daily life

① Control the movement of machinery, such as valve springs in internal combustion engines, control springs in clutches, etc.

② Absorb vibration and impact energy, such as buffer springs under cars and train carriages, and vibration absorbing springs in couplings.

③ Store and output energy as power, such as clock springs, Spring Spring in firearms, etc.

④ Used as a force measuring element, such as a spring in a force measuring device or spring scale. The ratio of load to deformation of a spring is called spring stiffness, and the greater the stiffness, the harder the spring.

According to the force properties, Torsion Spring can be divided into tension springs, compression springs, torsion springs, and bending springs. According to shape, it can be divided into butterfly springs, ring springs, plate springs, spiral springs, truncated scroll springs, scroll springs, and torsion bar springs. Generally, cylindrical springs are most widely used due to their simple manufacturing and the ability to be made into various types according to the load conditions, as well as their simple structure. Generally speaking, the manufacturing materials of springs should have high elastic limits, fatigue limits, impact toughness, and outstanding heat treatment functions. Commonly used materials include carbon spring steel, alloy spring steel, stainless spring steel, as well as copper alloys, nickel alloys, and rubber. There are two manufacturing methods for springs: cold coil method and hot coil method. Spring wire with a diameter less than 8 millimeters is generally rolled using cold rolling method, while those with a diameter greater than 8 millimeters are rolled using hot rolling method. Some springs require strong pressure or shot peening treatment after production to improve their load-bearing capacity.

Springs are widely used elastic components in mechanical and electronic work. When loaded, springs can generate significant elastic deformation, converting mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the spring disappears and returns to its original state, converting deformation energy into mechanical work.
