弹簧成形后，通常务必在220---330℃下退火或热烫，或依据弹簧工作条件和所选原材料的特性开展淬火和回火以提升弹簧力。但弹簧热处理时应选用卡具，以防圈缩小，工作时与轴棒卡牢。别的，如去除2个外端的角边和径向内外的毛边，不应忽视。当弹簧有弯曲倾向时，能够 运用1个圆沿拉紧弹簧的轴向开展多次纵向摩擦，使其在表层局部硬化。

    此外，弹簧力还与设计要素、原材料挑选要素等相关。从弹簧的2个关键计算公式，即变形公式lambda=8pd32n/gd4和应力公式_uu=k8pd2/pid3能够 看出，弹簧力受钢丝直径、环直径、变形和环数的危害很大，这与原材料特性、环境温度、载荷特性和环数密切相关。动态危害，会造成弹簧力和变形指示线异常。
