Suzhou spring manufacturers teach you how to choose the spring information?

Spring material selection? Spring manufacturers to tell you, should be based on the nature of the spring to bear the load, stress conditions, stress size, operating temperature, environmental media, service life, requirements for electrical and magnetic conductivity, process function, data history and price and other factors to admit.

When recognizing the shape and standard of the data section, priority should be given to the series of standards set by national standards and ministerial standards, and the selection of non-standard series of standards should be avoided as far as possible. Medium and small spring, especially spiral tension spring, should be given priority to the use of strengthened steel wire, lead bath and other warm drawn steel wire and oil quenched tempering steel wire, with high strength and outstanding surface quality, fatigue function is higher than the general quenched tempering steel wire, simple processing, good process, stable quality.

Carbon spring steel wire and piano steel wire after cold drawing, there is a large residual stress after processing the spring, there is a large residual stress, after tempering the standard change is large, it is difficult to control the standard accuracy. Oil quenching tempering steel wire is modulated and strengthened after the steel wire is drawn to the standard, basically no residual stress exists, after the forming spring is tempered at low temperature, the standard changes are small, and the heat stability is better than that of cold drawn strengthened steel wire.

Large and medium-sized spring, on the load accuracy and higher stress should be selected cold drawn material or cold drawn polished steel. For springs with lower load accuracy and stress, hot-rolled steel can be used.

The data section of the spiral spring should be prefered to use a circular section. Square and rectangular section data, strong ability to withstand, good impact resistance, but also can make the spring miniaturization

But the sources are few. And the price is high, in addition to special needs, generally try not to choose such information. In recent years, the research and development of round steel wire rolling instead of trapezoidal steel wire has achieved a good effect. The spring material operating at high temperature requires the strength to have good thermal stability, anti-relaxation or creep ability, anti-oxidation ability, resistance to certain medium corrosion ability.
