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.
