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.
as
compression spring, tension spring is also absorb and store energy.
But I don't like the compression spring most of the tensile spring usually under a certain degree of tension, even in the absence of any load.
This determines the initial tension in the absence of any load, tensile spring coiling of the close degree.
abstract: 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.
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.
