Tension at the beginning of the
spring tension: initial tension equal to that required to pull against each other in the spring and circle, tension in the early spring coiling occurs after forming.
Torsion spring, because of wire material, wire diameter, spring index, electrostatic, lubricating oil, heat treatment, electroplating, make each tensile spring initial produce uneven phenomenon.
The torsion spring, so the installation specification shall be of pretension to slightly apart some distance between each and circle.
At this time the force needed to become the initial tension.
initial tension = P -
K X l = large load
The spring constant tensile length X
tensile spring nettley, generally speaking, there are threads of embedded, cross center TAB, retractor, more holes, shrink pores, rectangular convergent and teardrop-shaped convergent, convergent from spring body length can be according to the specific circumstances.
More common is pegged to the extension spring, the 'hook' is a source of tension, its shape is circular cross section, easy fixed to the connected components.
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.
:
a number of different terminal device or a 'hook' is used to ensure tensile spring source of tension.
Contrary to the principle of compression spring tension spring.
Compression spring reverse effect at the time of compression and tension spring, a reverse effect at the time of stretching or open.
When tensile spring open on both ends, spring will be trying to bring them back to together.
The increasing consumption demand in key segments such as leaf spring hardware, leaf spring hardware and leaf spring hardware have been driving the sales of and its derivatives worldwide.
Dongguan Yongqiang spring hardware Co.,Ltd. didn’t receive any negative feedback from our customers before, which proves that customers have faith in us.
The first step toward Yongqiang’s successful selling campaign is to understand your customers. What are their needs or desires? Why would they support your product? Even more importantly, why would they be passionate about your product?
