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.
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.
pull at the beginning of the spring tension: the tension equal to open to each other at the beginning of spring and circle the required force, 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
formula:
spring constant: with 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 2.

Dongguan Yongqiang spring hardware Co.,Ltd. will become the destination store for customers, offering the convenience of multiple brands and channels, and providing a personal high touch shopping experience that helps create lifelong customer relationships.
Overwhelming customers with too much information or the slew of benefits News provides–even if they're all valid–is a surefire way to lose their attention.
