Introduction: closely around the circle, so that it can force and stretched, each side around a loop (
循环)
。
the following necessary for a stretch of the spring data:
1, free length, total length, long full circle, since the length of hook circles;
2, control the diameter, outer diameter, inner diameter, the inside diameter of casing;
3, steel wire size wire diameter;
4, materials (
Species, grade)
；
5, laps: the total number of turns and right-handed or left-handed;
6, the end of the form;
7, within the hook load;
8, load rate, deflection, every inch of pounds;
9, tensile length.
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.
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's 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.
is emerging as one of the most popular News, moving beyond its leaf spring hardware benefits, with conclusive scientific evidence suggesting the positive role play in leaf spring hardware.
A detailed plan must be developed if we hope to reach your profitability goal. Once we have a certain figure in mind, Dongguan Yongqiang spring hardware Co.,Ltd. and our staff need to determine all the steps necessary to reach that goal and act on them.
Dongguan Yongqiang spring hardware Co.,Ltd., which contributes itself on News for creating more useful application.
Dongguan Yongqiang spring hardware Co.,Ltd. harnesses science and technology to create products that support safer and healthier living and that enhance the overall quality of life.
We want to be careful and deliberate about developing Yongqiang, from the platform we choose, to the way we approach it, to the methods we use.
