Customized Wire Die Linear Wave Springs Manufacturer, Black Powder Coat Forming Wire Carbon /Stainless Steel Wave Linear
A wave spring is a compression spring made of coiled flat wire with waves added along the coils to give it a spring effect. can be used in place of conventional round wire compression springs in applications requiring tight load deflection specification in space critical environments. Generally, they occupy 30-50% of the compressed height space of comparable round wire springs offering more deflection with the same load specifications. This not only provides for space savings but also smaller assemblies that use fewer materials, hence lower production costs.
Springs are manufactured from a single filament of flat wire formed in continuous precise coils with uniform diameters and waves. They are manufactured with either Plain ends (wavy) or Squared-flat ends (shim ends). Generally, 17-7pH is used as the standard material for wave springs. Careful material selection is required for operating environments such as high temperatures and corrosive media.
Wave springs are found in a wide variety of applications where structural considerations restrict the installation height, where uniform force distribution is needed and/or uniform rotational pressure is required over 360°. They are suitable for both static and slightly dynamic load applications. However, fatigue is critical while designing a wave spring for dynamic load applications. For higher life cycles a stronger spring is needed. Special solutions must be found for extremely dynamic applications since considerable stress on the sine wave curves can cause material abrasion at the contact point. Typical applications include connectors, clutches, valves, pumps, seals, medical equipment, etc.

Prevention of fatigue failure of wave spring
The following is the calculation formula of the wave spring load and stress. We can use the formula to design the wave spring stress in a low-stress state, and the fatigue failure of the wave spring is not obvious.
(1) Calculation formula for single-layer wave spring: f=PKDm/Ebt3N4*ID/OD
(2) Multi-layer series or peak-to-peak wave spring calculation formula; f=PKDm3Z/Ebt3N4*ID/OD;
(3) Multi-layer stacked peak type, also known as nested or parallel wave spring calculation formula; F=PKDm3/Ebt3N4Z*IDOD;
Where: f=displacement; P=load; K=multi-turn coefficient; Dm=average diameter; Z=number of turns; E=modulus of elasticity; b=material width;
t=material thickness; N=wave number; ID=inner circle diameter; OD=outer circle diameter; S=bending stress; we found that the fatigue life of the wave spring is far more than 500,000 times through the fatigue test of the wave spring. More than 1 million times. Our company's outer diameter D=137mm, inner diameter d=125mm, thickness t=0.8mm, wave height H=6mm, when the working displacement is 3.5mm, the working force value F=1225N, this specification wave spring has passed a petrochemical enterprise for three years With more use, the spring has a life span of 1.8 million times, and some life spans are even higher.
Therefore, when designing the wave spring, we should choose a reasonable wave height and material thickness according to the load and displacement, effectively control the stress of the wave spring, and use the adjustable wave number to more effectively control the fatigue failure of the wave spring.
Application of Wave Springs
Aviation, automotive, motorbike, bicycle, automatic equipment, household appliance, medical device ,toy, telecommunication, computer, instrument and meter, furniture, electric tools, mold and other industries.
Characteristics of wave spring
(1) The rigidity range is large, the shock absorption ability is strong, and the concrete shape energy per unit volume is large.
(2) It has concrete stiffness characteristics. The stiffness can be corrected by changing the different combinations of peak height, width and thickness. The stiffness can also be adjusted by the number of combined pieces.
(3) Compared with disc springs, it has the advantages of high strength, good flexibility and strong impact resistance.
(4) The structure size is compact. Under the same physical parameters, the installation space is small.
Classification and working principle of wave spring
A common single-layer wave spring is an elastic element with several peaks and valleys on a metal ring. The multi-layer wave spring seems to be composed of several ordinary single-layer wave springs. The difference is that it is not simply superimposed, but is processed through a special continuous winding process.
Wave springs are usually divided into: a, single-layer wave springs,
The single-layer closed type is an "O"-shaped wave spring, and the single-layer open type is a "C"-shaped wave spring; b. Multi-layer peak-to-peak (series) wave spring; c. Multi-layered peak type is also called nested (Parallel type); single-layer wave spring: suitable for short-displacement and medium-low elastic working conditions, with good reliability and high working principle: wave spring has the accuracy of the dual working principle of cylindrical spring and disc spring . Multi-layer wave spring counter-peak type (series type): The elasticity value is inversely proportional to the number of turns. It is mainly used for: large displacement, medium and low elasticity requirements, and is a substitute for cylindrical springs. Nested type (parallel type): The force value of the spring is proportional to the number of turns. While huge elastic force is generated, all the precise characteristics of the wave spring can be maintained. In many occasions, nested (parallel type) wave springs can be used Used instead of disc springs.
The effect of material and temperature on fatigue failure For the same material: the material with fine grain structure has higher yield strength and fatigue elasticity than the material with coarse grain structure; the fatigue life of surface strengthened treatment is higher than that of unreinforced treatment Much higher; the smaller the surface roughness of the material, the smaller the stress concentration, and the higher the fatigue strength; the fatigue life of materials with metallurgical defects will also be greatly reduced, causing the spring to cause fatigue failure in advance. Wave springs made of ordinary spring steel have good elasticity, electrical conductivity, and wear resistance. The fatigue failure of the spring is within the normal range at normal temperature (temperature 200). However, as the temperature increases, the elasticity of the spring will gradually decrease, and the failure phenomenon will increase significantly.
Wave springs made of stainless steel have high fatigue life and good relaxation resistance. At the same time, stainless steel also has extremely high corrosion resistance and non-magnetic properties. Generally, the stainless steel will fail when the temperature is higher than 400. The special stainless steel has extremely high corrosion resistance and non-magnetic characteristics. The special stainless steel has high relaxation and fatigue resistance when the working temperature reaches 650, which cannot be replaced in special working situations. s material.

How to choose a spring manufacturer? We can judge by inspecting the following 10 points of spring manufacturers:
1. Types of springs that can be produced.
Different types of springs require different production equipment. The more types that can be produced, the more complete the production equipment of the company.
2. Ask about the production accuracy of the spring.
The precision of producing springs represents the production technology capability of the spring factory. The higher the production precision, the more attention the spring factory pays to the quality of the products.
3. Whether there is a research and development team.
The R&D team is indispensable for an enterprise. The R&D team of the spring factory can make this enterprise develop in the direction of new processes and new technologies. ~Innovative ability
4. Whether the production equipment is imported.
Most of the domestic spring equipment is used to produce some non-important parts of the spring, the overall production accuracy is low, and there is a certain gap in product consistency. The higher the precision of the spring equipment, the higher the precision of the spring can be made.
5. Output of spring production.
The production output of springs represents the production capacity of this enterprise. The greater the production capacity, the stronger the supply capacity and the stronger the relative delivery guarantee.
6. Which manufacturers are the suppliers for?
As the saying goes, to marry a wife, you must choose the right person, and you also need to find a partner. For example, you are in the automotive industry, and Xinxiang Huispring Spring Co., Ltd. is a spring for the automotive industry. They directly supply the German Bosch company, so the product quality must be very guaranteed. This is very suitable for you. If you are making a ballpoint pen and you want an ordinary ballpoint pen spring, then this bright spring spring may not be suitable for you. You should choose an ordinary spring factory.
7. Whether there is a special testing department and whether the testing equipment is complete.
The inspection department is a necessary department of the spring enterprise. If no one supervises quality control, or quality control cannot use effective equipment for inspection, then no one would dare to use such products.
8. What is the defective rate of the spring produced? ,
The defective rate of springs of qualified spring manufacturers is generally between 5 and 12 parts per million. This data contains the data of nonconforming products detected by the manufacturer. The smaller the data, the stronger the accuracy and consistency of spring production.
9. Where are the raw materials of the springs purchased and whether they are inspected plate by plate.
The production process of the spring is very important, and the raw material of the spring is more important. For the same material, some material dealers sell it for 5 yuan, and some material dealers sell it for 10 yuan. Why is this? On the one hand, it is the consistency of the steel wire, such as some places where it is thick and some places, on the other hand, whether the composition of the spring material is evenly distributed and whether the content is qualified. The spring produced by unqualified spring raw materials is also unqualified, such as frequent breakage or deformation, and the spring load cannot be reached.
10. Whether it has the qualification certificate of the relevant industry.
For the spring industry, are some certificates very difficult to obtain, such as IATF16949 and GJB 9001C. These are very rare certificates. If this spring company has these qualifications, at least it proves to be very formal.
Finally, we still have to conduct on-site inspections and see how much the registered capital of this spring factory is, so as to avoid subsequent supply problems.
