How to use the correct use of inclined coil spring, let Du Chenfa precision spring to tell you about it

1. Use more than the maximum compression

Pressure is used for a long time of pressure and causes damage, the damage is close to long time use, which will gradually reduce the spring line, because the higher the number of springs fixed will lead to high load, and high stress will lead to high pressure nearby, high stress will be caused by high pressure.

two There is no preloading

Because of the gap, the spring vibration is caused by the spring, and the spring is twisted.

Three, the use of spring horizontal use

When the spring is used horizontally, it will nurse the guide and the spring wear and break.

Four, when their flat surfaces are flat

When the component surface parallelism is poor, the spring will deform, local high pressure will break, and the occurrence of poor parallelism will cause spring distortion and cause more than 300,000 times spring break. Please increase the parallelism of the component without exceeding 300,000 times.

5. Relevant spring inner diameter and guide

After a few hours in which there is a gap between the derivations, collision and wear of the inner diameter will cause the spring to wear out. Instead, it will cause the spring to break. And for long springs, use steps or conditions to avoid collisions with guides while dispersing springs.

Six, spring diameter and rectangular head

The head hole and spring are too small, the external swelling on the outside will be concentrated, and the external hole friction will be concentrated due to the spring compression. The better the aperture diameter is the spring +1.5mm outside diameter. For free and longer spring shapes, use the head shape.

Seven, the head and head hole depth is very short.

The guide is too short, which will cause the derived head and spring to break. The ideal length of conduction is set to 1/2 the length of the spring. Please reflect the backward Angle of C3.

use

When using a spring, the spring will be distracting and will insert the external RA (or other scope inserted into the inflection point).

Series for spring use

When used in series, the spring is bent, the derivative or the hub length is exceeded, which will cause the same cause of fracture, and the load of the spring itself slightly different loads are weaker to withstand greater compressive surface fracture.

When foreign bodies are mixed

Mixed foreign parts will result in no compression of the effective volume. The substantial effective volume becomes smaller and close to the surface leads to high stress and fracture.
