冷卷圆柱弹簧时,首先要根据钢丝的种类和直径所需弹簧的中径,选择适当直径的心轴。在心轴上绕制弹簧时,盘绕力消失后,钢丝要回弹,而回弹的预先确定则比较困难。有关资料所提供的经验公式和心轴直径表与实际情况出入较大,难以满足生产需要。本文根据实际工作所积累的一些数据,结合有关资料,归纳出 Cold-rolled cylindrical springs, the first according to the type of wire and diameter of the required diameter of the spring, select the appropriate diameter mandrel. When the mandrel is wound around the spring, the wire will rebound after the coiling force disappears, and the predetermined rebound will be more difficult. The information provided by the empirical formula and the spindle diameter table and the actual situation of a larger discrepancies, it is difficult to meet production needs. This article based on the actual work of some accumulated data, combined with the relevant information, summed up
