ZHENGDE Spring is the most commonly used part in the machinery industry and in daily life. The main function of the spring is to use the energy stored in its own deformation to ease the vibration and impact of the machine or parts, and to control the movement of the machine or parts.
The use characteristics and uses of spring steel wire
The spring is used within the elastic range, and it should return to its original position after unloading. It is hoped that the plastic deformation should be as small as possible, so the steel wire should have high elastic limit, yield strength and tensile strength. The higher the yield ratio, the closer the elastic limit is to the tensile strength, so the higher the strength utilization rate is, the stronger the elastic force of the spring is.
The spring relies on elastic deformation to absorb the impact energy, so the spring steel wire does not have to have high plasticity, but at least it must have the plasticity to withstand the spring forming and enough toughness to withstand the impact energy.
Springs usually work under alternating stress for a long time, so they must have a high fatigue limit, as well as good creep and relaxation resistance.
