3.0mm cone compression spring
Customized Metal Coil 3mm Cone Tower Shaped Tapered Conical Compression Spring
Spring diameter and pitch are unchanged cylindrical helical spring characteristic line is linear, and the characteristic line of the conical coil spring is nonlinear. When the process pressure of the conical coil spring, the coil spring near the large end of the larger value of c, a smaller value of c softer small end of the spring, the spring harder. Softer spring ring portion of the first work and tight, the first lap (starting from the number of big-endian) and immediately before the size of the force and deformation of the spring and later still proportional tight, and tight coil is not and then to work. Therefore, with the increase in the degree of deformation, the number of spring turns participating in the work will be less and less, and the spring index will develop toward a smaller direction, which will make the spring more harder. So the characteristic line of conical spiral bombardment is a line connecting a straight line and a curve. Conical coil springs can only be used as compression springs.

Types and characteristics of cylindrical spiral compression springs
1. Cylindrical helical compression spring with circular cross section: most of this spring is made of high carbon steel and stainless steel. Its characteristic is that the force value is linear, the structure is spiral, it is convenient to manufacture, and it is also the most widely used compression spring. .
2. Cylindrical helical compression spring with rectangular section: This kind of spring has the characteristics of occupying a small space and can absorb more energy, and the force value is also linear, but it is difficult to manufacture and requires special tooling.
3. Flat section cylindrical spiral compression spring: This kind of spring is very close to the former, but because it is made of materials that are flattened by round wires, the service life will be much longer than the former.
4. Unequal pitch or variable pitch, variable stiffness, cylindrical spiral compression spring: When the spring is working, the force value characteristic is nonlinear, and the stiffness and natural frequency are not fixed. This feature is beneficial to eliminate mechanical resonance. Phenomenon, often used in mechanical equipment supporting high-speed variable loads.
The last type is a multi-strand helical compression spring: this spring steel wire is not an ordinary round wire steel wire, but a steel wire formed by twisting several thin steel wires together. The characteristic is when the load reaches a certain amount when the compression spring is working. The line will find the turning point. It has greater strength than ordinary round wire springs, and has obvious shock absorption effect. It is mostly used in engines.
For the material cross section of the coil spring, a circular cross section should be preferred. Square and rectangular cross-section materials have strong bearing capacity and good impact resistance. It can also miniaturize the spring, but there are few material sources. And the price is high, except for special needs, generally try not to choose this material. In recent years, the development of flattened round steel wire instead of trapezoidal steel wire has achieved good results.
Spring materials that work at high temperatures require good thermal stability, resistance to relaxation or creep, resistance to oxidation, and resistance to certain medium corrosion.
As the working temperature of the spring increases, the elastic modulus of the spring material decreases, resulting in a decrease in stiffness and a decrease in load-bearing capacity. Therefore, the spring working at high temperature must understand the change rate (value) of the elastic modulus, and calculate the influence of the drop in the load capacity of the spring on the performance. According to the provisions of GB1239, when the working temperature of ordinary coil spring exceeds 60℃, the shear modulus should be corrected. The formula is: Gt=KtG in the formula G—the elastic modulus at room temperature; Gt—the shear modulus at the working temperature t Quantity; Kt—temperature correction coefficient is selected according to Table 2-98.
The spring material used at low temperature should have good low temperature toughness. Carbon spring steel wire, piano steel wire and austenitic stainless steel spring steel wire such as 1Cr18Ni9, copper alloy and nickel alloy have good low temperature toughness and strength.
At low temperatures, the brittleness of the material is very sensitive to surface defects, so the surface quality of the material should be strictly required.
At low temperatures, the environmental media has much less corrosion to materials than in the greenhouse, and cadmium and zinc plating are likely to cause cold brittleness.
At low temperatures, the elastic modulus and expansion coefficient of the material do not change much, so it can be ignored in the design.
For springs made of spring steel, the hardness (that is, strength) should be selected according to the nature of the spring load and the magnitude of the stress. However, the hardness has a great relationship with the plane strain fracture toughness.
It can be seen from the curve relationship that as the hardness increases, the plane strain fracture toughness (KIC) value decreases significantly. This means that when determining the hardness value of the spring, it should be based on the premise of meeting the requirements of the spring characteristics, and the hardness value of the spring should be lower.
When selecting spring materials, pay attention to the hardenability of the steel. Whether the cross-section of the spring material is hardened and the degree of hardening have a great bearing on the quality of the spring.
Electrical springs that use the spring itself as a conductor or springs that work in an environment with variable humidity, such as water (including sea water) and steam, generally use copper and gold materials.
Springs that work under acid contact with other corrosive media generally use corrosion-resistant materials such as stainless acid-resistant steel or nickel alloy. For springs used under general environmental media conditions, ordinary spring steel is selected, and the surface of the spring is made of anti-rust coating or electroplating (galvanized, cadmium, copper) to prevent corrosion.
In order to ensure that the accuracy of the springs used in weighing instruments and meters is not affected by temperature changes, constant elastic alloys with minimal changes in elastic modulus and expansion coefficient are generally used.
Reinforced plastics can be used for special-purpose springs that require light weight, insulation, anti-collision, anti-corrosion, etc. At present, the more suitable plastic springs are thermosetting reinforced plastic GFRP with epoxy resin and phenolic resin as the matrix and glass fiber reinforced. Various types of rubber springs can also be made of anti-vibration rubber.

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.
