摘　　要：针对一般用途的小型螺旋弹簧,可在普通车床上用冷成型法卷制成型,卷制的原理与车螺纹基本相同。芯轴是卷制弹簧的主要工具。芯轴的长短根据弹簧长度决定,芯轴的直径大小非常重要,芯轴的直径可用经验公式计算,特别适合单件、小批量生产。Small-sized coil springs for general purposes are rolled by cold forming on a common lathe.The rolling principle is basically the same as that of thread turning.The mandrel is the main tool for rolling the spring.The length of the mandrel is determined by the length of the spring.The diameter of the mandrel is very important.The diameter of the mandrel can be calculated by empirical formula,which is especially suitable for single-piece and small-batch production.
