Characteristics and applications of spring steel wire

1, the spring is used in the elastic range, and should be restored to its original position after unloading. Plastic steel wire should have a high elastic limit, yield strength and tensile strength. The higher the yield ratio, the closer the elastic limit is to the tensile strength, the more it can improve the strength utilisation, the stronger the spring.

2, the spring is to rely on elastic deformation to absorb the impact energy, so the spring steel wire does not have to have a high degree of plasticity, but at least have to be able to withstand the plasticity of the spring moulding, and can withstand the toughness of the impact energy.

3, springs usually work under alternating stress for a long time, so they must have a high fatigue limit, as well as good creep resistance and resistance to relaxation.

4、Anti-shock and cushioning, play the role of strong vibration. For example, car shock absorbers are designed using this principle. The principle is to give the opposite force in a certain direction, and produce a certain amount of displacement, thereby reducing vibration.

5, spring wire load, the spring will be deformed when it is subjected to external force, the external force will impose a load on the spring steel wire. Spring steel wire should be able to withstand this load, otherwise it will be damaged. When purchasing spring steel wire, the maximum load of the spring steel wire must be considered.

6, force measurement, for example, the force gauge used is designed to utilise the force measurement principle of the spring.

7、Strengthening, springs also provide reinforcement to reduce wear and tear between mechanical parts.

8, springs for precision instruments should have long-term stability and sensitivity, low temperature coefficient, high quality factor, small after-effects, and constant modulus of elasticity. Springs working at high temperatures need to maintain sufficient elastic limit and good creep resistance at high temperatures.

Spring steel wire is widely used in machinery manufacturing, industrial production, etc. So what are the main applications of the product?

Energy storage and kinetic energy conversion spring steel wire has the function of energy storage and kinetic energy conversion, which can convert kinetic energy into elastic potential energy. It can also convert elastic potential energy into power, to achieve the effect of energy conversion. For example, automatic switches are designed to take advantage of spring energy conversion. For example, the shock absorber of a car is designed using this principle. The principle is to give an opposite force in a certain direction and produce a corresponding displacement, and then get a cushion.

The spring wire load spring deforms when it is subjected to an external force and the external force gives a load to the product. The product can withstand this load, otherwise it will be damaged and needs to be considered when purchasing.

Products used for corrosive media must have good corrosion resistance. Products used for precision instruments should have long-term stability and sensitivity, low temperature coefficient, high quality factor, small after-effects, and constant modulus of elasticity. Spring steel wire working under high temperature conditions is required to maintain sufficient elastic limit and good creep resistance at high temperatures.
