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.
