Tempering treatment of compression springs

Tempering treatment of compression springs



Compression springs standard specification model_compression springs as a basic part, it will directly affect the use of various products. Many furniture do not have springs, and people’s living comfort will be reduced in a straight line, which will also bring a lot of inconveniences. For example, sofas without springs, people are like sitting on a hard wooden board, there is no elasticity at all, and they can’t bring people comfort. Sense, so spring can be said to have become an indispensable product in life. In addition, without the existence of the spring, the entire equipment will not be able to work and will directly enter the scrapping stage. It is the spring that is so important that people need to heat and temper it, so why does the spring need to be tempered?

 One is to strengthen the tensile strength. One of the purposes of tempering treatment is to increase the resistance strength of the steel, to ensure that it can rebound normally, and to ensure the effect of the spring. The spring after tempering can increase the tensile strength to more than 90%, reducing the creep resistance of the spring.
The second is to release the residual stress. In fact, the tempered spring can release the residual stress in time so that it can be normally drawn or rolled. In this way, the service life of the spring can be gradually increased, and fatigue performance and creep can be reduced.
The third is to stabilize the shape of the spring. After the tempering treatment, the action of the spring can directly stabilize the shape of the spring. Make it not easily deformed. In this way, the stretching effect of the spring can be guaranteed.
