碟形弹簧以其减振能力强、轴向空间小、更换容易而被广泛地应用于冶金、矿山、国防及交通运输设备上。其形状虽然简单,但加工成型却都存在着变形量大、强度上不去等许多难点,以至一些厂家生产碟形弹簧的合格率超不过50％,尤其是有些对变形要求较严的单位,往往因碟形弹簧合格率低于部颁标准而使其批量报废, Disc spring is widely used in metallurgy, mining, national defense and transportation equipment due to its strong vibration-reducing ability, small axial space and easy replacement. Although its shape is simple, but there are deformation of the processing of large deformation, the strength does not go up and many other difficulties, as well as some manufacturers of disc springs exceeded 50% pass rate, in particular, some of the deformation of the more stringent requirements of the unit, Often due to lower than the pass rate of the concession standard makes the batch scrapped,
