Abstract
A kind of production method of spring, comprises the following steps：（1）Roll：Temperature during hot rolling is in the range of 300 ~ 370 DEG C, and the pitch of spring is 5 8mm；（2）Stress relief annealing：To make the temperature after shackle completion of processing lower 10~15 DEG C than the temperature after rolled during stress relief annealing, the internal stress formed when rolling can be eliminated, stabilizing spring size improves the tensile strength and elastic limit of wire；（3）Two ends to grinding, back-end crop；（4）Halt or swirling flows：The bearing capacity 25% of spring static load can be improved；（5）Examine；（6）Surface is turned blue processing：Its surface is set to produce very thin oxidation film, corrosion stability and friction resistant performance are improved；（7）Packaging；The present invention disclosure satisfy that fatigue test requirement, by 5 × 106Do not occur fatigue fracture after secondary circulation and fracture, ensure that longer service life and higher use intensity.
Description
Technical field
The invention belongs to mechanical field, specifically a kind of production method of spring.
Background technology
As China's transport service is continued to develop towards direction at a high speed, heavily loaded, higher requirement is proposed to the fatigue strength of vehicle component.It is used as the key components and parts of roller bearing adapter stabilizer bar, body spring is realizing uniformly transferring for car load, in terms of relaxing vibration caused by guideway irregularity and impacting, play vital effect, therefore, it is guarantee driving safety, in the urgent need to carrying out Fatigue reliability testing checking to body spring, to ensure service life and intensity, the fatigue reliability of body spring has safely vital effect for the operation of lorry.
The content of the invention
It is an object of the invention to provide truck headache driving can be met, meet the production method of the spring of Fatigue reliability testing requirement.
A kind of production method of spring of the present invention, comprises the following steps：
（1）Roll：Temperature during hot rolling is in the range of 300 ~ 370 DEG C, and the pitch of spring is 5-8mm；
（2）Stress relief annealing：To make the temperature after shackle completion of processing lower 10~15 DEG C than the temperature after rolled during stress relief annealing, the internal stress formed when rolling can be eliminated, stabilizing spring size improves the tensile strength and elastic limit of wire；
（3）Two ends to grinding, back-end crop；
（4）Halt or swirling flows：The bearing capacity 25% of spring static load can be improved；
（5）Examine；
（6）Surface is turned blue processing：Its surface is set to produce very thin oxidation film, corrosion stability and friction resistant performance are improved；
（7）Packaging.
The spring produced through the inventive method, ensure that longer service life and higher use intensity, fatigue test requirement be disclosure satisfy that, by 3 × 106Do not occur fatigue fracture after secondary circulation and fracture.
Embodiment
A kind of production method of spring of the present invention, comprises the following steps：
（1）Roll：Temperature during hot rolling is in the range of 300 ~ 370 DEG C, and the pitch of spring is 5-8mm；
（2）Stress relief annealing：To make the temperature after shackle completion of processing lower 10~15 DEG C than the temperature after rolled during stress relief annealing, the internal stress formed when rolling can be eliminated, stabilizing spring size improves the tensile strength and elastic limit of wire；
（3）Two ends to grinding, back-end crop；
（4）Halt or swirling flows：The bearing capacity 25% of spring static load can be improved；
（5）Examine；
（6）Surface is turned blue processing：Its surface is set to produce very thin oxidation film, corrosion stability and friction resistant performance are improved；
（7）Packaging.
