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.
:
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.
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.
application:
tension springs and spiral extension spring, generally for pitch, such as cross section is round more, they can be used in many occasions, such as production assembly, experiment, research and development, maintenance, etc.
Tension spring occupies an important position in the global market, widely used in national defense, Marine, computer, electronic, automotive, mold, medical, biological, chemical, aerospace, railway, nuclear power, wind power, thermal power, engineering machinery, mining machinery, construction machinery, elevator, etc.
