Buckle definition: is the use of material elasticity and composition characteristics, through deformation and storage of energy work of an armored part.
Pressing uses: shock absorbers, clamping, force measurement, energy storage, and good contact or disengagement between other parts.
Spring in the process, there is a hot roll buckle cold roll this point. The main differences between the two are:
1) Materials selected carbon spring wire, piano wire, bronze wire and so on.
2) Heat treatment: after forming for desaltation and de-ignition treatment, its hardness is not in the assessment. Des stress aer than required also allows for deseeding and de-ignition treatment.
3) The spring of the first cold roll with hard state of bronze should be deseeded and de-ignited. Its hardness is not in the assessment. The spring of the first cold roll with cold hard palladium bronze should be time-age.
