介绍了由辗压螺纹毛坯直径理论计算公式推导辗压毛坯极限直径计算式的过程。利用该公式 ,根据已知被辗压螺纹的精度、直径、螺距、牙型和螺纹刀具精度等参数 ,即可算出辗压螺纹的毛坯直径。该公式适用于计算多种对称牙型的圆柱螺纹 (如米制、英制、美制等各种精度等级的螺纹 )辗压前的毛坯直径。该计算方法经多年实践证明具有适用范围广、准确性高、计算简便等特点
The process of deducing the formula of the limit diameter of rolling blank by the theoretical calculation formula of rolling screw blank diameter is introduced. Using this formula, the diameter of the blank for the rolling thread can be calculated from the known parameters such as accuracy, diameter, pitch, type of tooth profile, and thread tool accuracy of the rolled thread. The formula is suitable for calculating a variety of symmetrical teeth of the cylindrical thread (such as metric, British, American and other precision grade thread) before rolling rough diameter. After years of practice, this calculation method has proved that it has a wide range of applications, high accuracy, easy calculation
