Formula:
spring constant: k said, when the spring is stretched, each additional load (1 mm distance
kgf /毫米)
spring constant formula (
Unit: KGF/mm)
:k = (
G*d4）
/（
8*Dm3*Nc）
G: module of rigidity of wire;
D: wire diameter;
Dm: - pitch diameter = diameter
Wire diameter;
Nc: laps = total number of laps - effectively

talking about spring, a lot of people are not strange, has been widely applied in life.
Spring tension spring and
compression spring, in this paper, mainly explain is one of the characteristics of extension spring, often used in some hand tools, shock absorbing device, switch equipment tools, such as machine, some control valve can be helpful in various fields, and materials of diversity.
Here, small make up on tensile spring characteristics and how to detect the features, help you to understand the tension spring.
in the spring, in the process of heat treatment and quenching cooling rate should be controlled tensile spring products, in order to obtain high and even hardness and enough hardening layer depth, at the same time reduce the deformation and prevent cracking.
What is the action of tensile spring quenching:
1, steel hardenability: hardenability is also called the hardenability, is refers to under prescribed conditions, the hardening depth and hardness of the steel sample distribution characterized by material performance.
These are the characteristics of steel itself;
2, to stretch the spring products, steel grade requirements for the carbon content is 0.
50% -
0.
75%, manganese element is zero.
50%.
Carbon and manganese are affect the hardenability of elements.
Due to the domestic steel hardenability band wider, quenching oil cooling rate should be according to the condition of low hardenability choice;
3, fast quenching oil is mainly used for thickness or diameter smaller alloy constructional steel and carbon steel spring.
Spring enterprise all hope each heat treatment furnace can deal with more specifications of the spring.
extension spring characteristics test
the spring size including outside diameter, inside diameter, spring wire diameter, free length and tensile length.
In testing is often necessary to test the spring load and stress, this time to consider extension spring free length and the length, is the spring in the no load state and the length of the large tensile condition.
is a modern News widely used in leaf spring hardware industry. It also enhances the quality leaf spring hardware value of the products.
