What are the material requirements for the manufacture of bevel coil springs?


1. High intensity


In order to improve the ability of the inclined coil spring to resist fatigue damage and slack, the beveled coil spring material should have high yield strength and elastic limit, especially a high yield ratio. In general, the elastic limit of a material is proportional to the yield strength, so bevel coil spring designers and manufacturers always expect a material with high yield strength.


2. Outstanding plasticity and resistance


In the manufacturing process of beveled coil springs, the material needs to undergo different degrees of processing deformation, so the material is required to have certain plasticity. For example, the hook loop and torsion arm of the stretching and torsion bevel coil spring with complex shape, when the radius of curvature is very small, when processing winding or stamping bending forming, the bevel coil spring material must not show cracks, damage and other shortcomings. When the bevel coil spring receives shock load or variable load, the material should have good resistance, which will be of great benefit to improve the service life of the bevel spring.

3. Excellent appearance state and fatigue function


The sloped coil spring I is used as the external stress Z is large, and the fatigue failure is often from the appearance of the wire, about the use of important occasions of the inclined coil springs such as valve inclined coil springs, valve inclined coil springs and suspension inclined round springs are required to have millions of times, tens of millions of times or even longer cycle life, which puts forward high requirements for the fatigue function of the material. There are many factors that affect the fatigue function of materials, such as the chemical composition of materials, hardness, purity of steel, surface quality and metallographic structure, etc., and the surface quality of materials is particularly important.


4. Strict size


Many inclined coil springs have high requirements for load accuracy, such as the load error of gas i inclined coil spring should not be greater than 5%--6% of the regular load, taking the pulling and pressing inclined coil spring with round steel wire as an example, if the wire diameter error is 1%, the load will produce an error of about 4%. It can be seen that strict dimensional accuracy is also very important to ensure the quality of the bevel coil spring.


5. Good uniformity


The uniformity requirements of materials refer to the requirements for uniformity and stability of various indicators such as chemical composition, mechanical function, and dimensional error of materials. If the functions of all aspects of the material are not common, it will bring great difficulties to the production of bevel coil springs, forming the discreteness of product geometry, hardness, load and other parameters, serious unevenness and even the formation of scrap. Strap fingers
