What is the difference between a tension spring and a compression spring?

2022-08-29

The tension spring is a coil spring that bears the axial tension, and its hooks are in the form of side hook tension spring, long hook tension spring, English hook tension spring, German hook tension spring, semicircular hook tension spring, duckbill hook tension spring, etc. , "Hook" is used to ensure the source of tension of the tension spring. It is generally made of spring steel with a circular section. When it is not under load, the rings of the tension spring are generally tight and there is no gap. The rebound force (tension) after extension is used to control the movement of the parts, store energy, measure the size of the force, etc. Most extension springs are usually under a certain degree of tension, even without any load. case. This initial tension determines how tightly the tension spring coils without any load. There are many kinds of springs, their functions are also different, and the forces they bear are also various. For example, pressure refers to the working pressure that the compression spring can withstand, such as the shock spring of a vehicle, and torsion refers to the torsion force that the torsion spring can withstand, such as wood. The torsion spring and tension spring of the clothespin are the test tension, such as the tension spring of the spring balance, the rebound force such as the work of the mainspring and so on.

In packaging machinery, the tension spring is generally used for the reset of the actuator, and the force is relatively small, such as the reset after the cam exerts force on the actuator. The function of the compression spring is generally used for strength buffering. For example, if the two sealing props must have a buffer, a compression spring or a buffer pad is required, but the compression spring can withstand high temperature, and the buffer pad cannot do so, so the compression spring is very useful in packaging machinery. widely.
