The compression spring is a kind of hardware fittings with spiral geometry shaped by wire. So his stiffening operation is more difficult than flat hardware accessories, in addition to the strict control of compression spring cross section of the stiffening effect. Therefore, the resistance to fatigue fracture of the decompression spring is sufficient.

Compression spring design production

See actual product demand to choose spring material according to the standard.

According to the product strength and compression stroke, fatigue and other requirements. Determine the inner and outer diameter of the spring and the effective number of turns. And the value range of the line diameter.

Substitute the related parameters into the design parameter formula.

It is reasonable and feasible to design and produce the spring by the spring manufacturer.

Compression spring strengthening process

Shot peening and hard compression spring treatment: to deal with a batch of pressure springs, the compression spring can be sent to the shot blasting room by a separate conveyor belt, shot blasting city is equipped with a group of parallel bars, while strengthening the roll to roll. Drive the edge of the compression spring to rotate forward, so that the high-speed shot can flow through the coils of the compression spring. Hit to the metal surface of the inner ring, that is exactly where the stress of the compression spring is concentrated, shot peening is a better reinforcement of the suspension spring, high stress spring after the appropriate shot peening fatigue life can be increased by more than 4 times.
