Compression spring must be very familiar with you, in life everywhere plays a key role. We have to learn it in many ways, in fact, we have been using it, more or less there are some improper use method. So how does the compression spring work correctly?

1, spring horizontal application

When the spring is applied horizontally, the guide pin and the spring will wear and break.

2. Poor flatness of the assembly surface

When the parallelism of the assembly surface is not good, the spring will be twisted, and the high pressure fracture will be caused locally. When the parallelism is bad, the spring will be twisted and the spring will be broken if the application exceeds 300,000 times. Please improve the parallelism of the assembly surface within 300,000 cycles of application.

3. Application without preloading

Spring up and down because of the gap caused by spring vibration spring distortion, such as when there is prepressure, the spring is more stable.

4. Applications that exceed a large amount of compression

Caused by pressure and then cause damage, close to the application of dense long, will make the spring line gradually dense so, due to the metal spring set number of high load curve resulting in high, close to cause high stress spring fracture, please do not apply more than 300 thousand times.

5. Application of spring-free guidance

If it is applied without spring guidance, it is easy to cause the bottom of spring and the body to be twisted, and the local high pressure of the twisted part is the main cause of spring fracture.

6, spring outside diameter and countersunk hole

If the countersunk head hole and the spring clearance head are too small, it will be caused by the spring compression that the outside of the countersunk head hole is enlarged and the friction between the countersunk head hole will lead to concentrated fracture of force. The better countersunk head aperture is the outer diameter of the spring +1.0mm. Free long springs with countersunk head hole shape.

7. Guide pin length and countersunk hole depth are short

If the guide pin is too short, the head of the guide pin and the spring will be worn and broken. The ideal length of the guide pin should be more than 1/2 of the length of the spring, and the chamfering Angle of C3 should be inverted.
