Believe spring need to electroplating processing is known to all, but as we all know, need to make their spring after tempering,
The heat treatment)
?
Tell us why spring under the tempering process, the need to do what need to be aware of tempering process?
one, why should spring tempering treatment?
1, to increase the material yield strength to tensile strength of about 90%, improve spring creep properties.
2, release drawing and residual stress caused by spring coiling process, improve the fatigue and creep properties.
3, stable spring shape: 15 - tempered After 30 minutes spring outer ring will shrink to a stable level.
2, spring temper handle matters need to pay attention to what?
1, avoid to improve temperature, shorten the time of spring temper processing way.
2, hardness: along with the increase of tempering temperature, the hardness increased slightly after the fall. Fatigue performance of the best slightly below the hardness of the maximum temperature.
3, reducing: carbon steel spring temper diameter will shrink, so should set aside some sizes in the coil spring.
4, spring heat tint: heat tint is related to temperature and residue on the surface of the steel wire, color uneven temperature distribution and the airflow or the chamber of a stove or furnace.
5, and if you expect even color, to manage the furnace and the loading way; If you have any oil or partial fingerprints, will change color after tempering.
6, tempering temperature: generally USES the tempering temperature - in 250 200-280 ℃, if adopted 250 ℃ processing wire, although can improve the strength, but plastic toughness will loss, can lead to tension spring hook or torsional spring bending leg when a fault occurs.
7, compression spring: hammer on mild hypothermia after tempering can reduce the deformation.
8, tension spring: after tempering treatment early stress there will be a loss, loss should be considered when setting deviation allowed.
9, torsion spring, coil spring after 280 ℃ tempering treatment, such as coil spring to rework, after low temperature tempering temperature is 250 ℃.
10: the hook and torsion spring, tension spring arm position will change after tempering, for accurate position requirement, should grasp the variation.
The point for Dongguan Yongqiang spring hardware Co.,Ltd. is that managerial processes are as important as other inputs in production and can create significant competitive advantage.
And finally, if you want to find additional resources for News, simply go to Yongqiang Spring Hardware for more.
The best way of leaf spring hardware is to get a leaf spring hardware News.
