Custom manganese steel high elastic tension spring

The hook forms of the extension spring include side hook extension spring, long hook extension spring, English hook extension spring, German hook extension spring, semicircular hook extension spring, duckbill hook and so on. Its materials include stainless steel, piano steel, high carbon steel, phosphor bronze, oil tempered alloy spring steel, etc.


Tension springs (also called tension springs, referred to as tension springs) are helical springs that bear axial tension. Tension springs are generally made of round cross-section materials. When not under load, the coils of the tension spring are generally tight and there is no gap.


Many different terminal devices or “hooks” are used to ensure the source of the tension spring. The working principle of the extension spring is opposite to that of the compression spring. The compression spring acts in the opposite direction when it is compressed, and the extension spring acts in the opposite direction when it is stretched or pulled apart. When the ends of the tension spring are pulled apart, the spring will try to pull them back together. Like compression springs, extension springs also absorb and store energy. But unlike compression springs, most extension springs are usually under a certain degree of tension, even without any load. This initial tension determines how tightly the tension spring is coiled without any load.

Tension springs, also known as spiral tension springs, are generally of equal pitch and mostly circular in cross section. They can be used in many occasions, such as production and assembly, experimentation, research and development, and maintenance. Tension springs occupy an important position in the global market and are widely used in national defense, marine, computer, electronics, automobiles, molds, medicine, biochemistry, aerospace, railways, nuclear power, wind power, thermal power, construction machinery, mining machinery, construction machinery, Elevator and other fields.
