①低温碳氮共渗的方法http://www.diannaothj.com  弹簧机  
Low temperature carbon and nitrogen co permeation method
采用回火与低温碳氮共渗相结合的技术,可以有效地提升压缩弹簧电脑压簧机的疲劳系数和耐腐蚀性,因而此项技术多被应用于卷簧中。
By the combination of tempering and low temperature nitriding, the fatigue coefficient and the corrosion resistance of the compression spring machine can be effectively improved.
②弹簧等温淬火的方法
Spring isothermal quenching method
直径较小或透性满足的弹簧产品可采用等温淬火的方法,其仅能削减变形,而且还能提升行进强耐性。在等温淬火后佳再进行一次回火处理,可增强弹性极限,回火温度与等温淬火温度保持一致。
Small diameter or permeability to meet the spring products can be used in the method of isothermal quenching, which can only cut deformation, but also enhance the strength of the travel. After isothermal quenching, the optimum tempering process can be carried out, and the elastic limit can be enhanced, and the tempering temperature is consistent with the isothermal quenching temperature.
③喷丸处理的方法
Method of shot blasting
弹簧表面有划痕、折叠或氧化脱碳等缺点通常会成为压缩弹簧电脑弹簧机作业时应力会集和疲倦开裂的源头。若用纤细的钢丸高速喷打弹簧外表,不仅能改进弹簧外表的质量、行进外表强度,而且在弹簧外表处于压力状态下能够增强进行疲劳强度和延长使用寿命。
Spring surface scratches, folding, or oxidation and decarburization, shortcomings will usually become compressed spring computer spring machine operation should be force to gather and fatigue crack source. If slender steel shot high-speed penda spring appearance, not only can improved spring appearance quality, the road surface strength, but also in the spring appearance in pressure can enhance for fatigue strength and prolong the service life.
④形变热处理的方法
The method of thermomechanical treatment
将热处理强化和两钢的变形强化两者相结合,以更好的发挥弹簧钢的强度和耐性。在形变热处理中有高、中和低温之分。其中高温形变热处理是在稳定的奥氏体状态下发生形变后立即淬火,也可与热轧或铸造相结合起来,即热成型后当即淬火。因而形变热处理方法已被广泛应用于汽车板簧生产中。
The combination of heat treatment and deformation hardening of two steel in order to better exert the strength and tolerance of spring steel. There are high and low temperature in deformation heat treatment. The high temperature deformation heat treatment is in a stable state after the deformation of the austenitic deformation immediately after quenching, can also be combined with hot rolling or casting, that is, immediately after the hot forming quenching. The thermomechanical processing method has been widely used in the production of automobile leaf spring.
