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.
tensile spring associated standards:
GB/T_1239 [

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.
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.
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.
