In a tensile
spring heat treatment and quenching process, the cooling speed 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.
tensile spring associated standards:
GB/T_1239 [
1]
。
1 -
2009 _ _ cold roll of cylindrical helical spring technology conditions, part 1: tension spring;
GB / T2087 -
2001 cylindrical spiral tensile spring size and parameters: GB/T 2008 -
1997, etc.
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.
extension spring feature
the spring is under axial tension spring, stretching after pulling force is used to store energy, it will try to back together after open, produce to the force majeure.
When not bearing, is between tension spring coil and tight, so tensile spring coiling of the close degree is decided by the initial tension.
Its general with stainless steel, piano steel, high carbon steel, phosphor copper, oil tempered alloy spring steel, etc
To that end, Dongguan Yongqiang spring hardware Co.,Ltd. has successfully built a solid foundation and infrastructure for News manufacturing.
Dongguan Yongqiang spring hardware Co.,Ltd. will accomplish this by exceeding the expectations of our customers while conserving resources and preserving the quality of the environment.
The same determination is critical for business owners. The journey in News business is both a challenging and rewarding experience.
The risk of leaf spring hardware is reduced by leaf spring hardware with the consumption of .
In order to obtain the most suitable for your leaf spring hardware, you need to contact qualified suppliers which can produce super quality to your specifications and offer a friendly price.
