Spring factory how to improve the spring reduction feature

2020-10-23
As spring is more and more big, the demand for the standard specification is becoming more and more high, so the spring factory applied various ascension process to improve the quality of the spring, improve play yellow feature reduction play the making craft of common preventive measures are: resilience quenching treatment and electromagnetic induction heating,
1)
Resilience quenching
resilience quenching process in quenching released on both sides of the stainless steel wire is equal to the tensile strength by 30% ~ 50% of the tensile stress field, stainless steel wire under the action of tensile strength in trace element resilience, mobile dislocation line. By this time the amount of clearance material concentration atoms ( C and N) With temperature diffusion, near to the dislocation line will move with the dislocation of 'pinning' live. In addition in the quenching process dissolution of cementite provides many pinning points, the dislocation 'pinning' more completely, more abundant, improves the immune ability, stainless steel wire plastic deformation to improve the play reduction characteristic of the stainless steel wire. ( 2) Electromagnetic induction heating process faster electromagnetic induction heating, stainless steel wire surface oxidation is light, not easy to cause the nitriding, crystal is also improved. Electricity induction heating equipment in the production of manufacturing oil conditioning - processing Stainless steel wire is quenching pressure spring, strong plasticity, under static load and load feature reduction is very good, in the spring under the various indicators keep the original level specification, turnning reduce 10% ~ 20%. Rubber shock absorber factory very is containing niobium and vanadium alloy steel, only the higher transition temperature of ferrite made abundant niobium and vanadium, melting to obtain secondary hardening quenching expected effect. Under the general heating specification, ferrite transition temperature is too high, crystal coarsening, stainless steel wire surface oxidation, nitriding also sharply increase, a serious threat to fatigue life. Electromagnetic induction heating to 900 ~ 1200 ℃, nitriding, stainless steel wire is not easy to happen serious oxidation and crystal coarsening. She said can make the electromagnetic induction heating containing niobium and vanadium steel makes full use of advantages.
