一、普通螺纹的体积公式推导机械加工中,滚压外螺纹的毛坯尺寸,在一些资料介绍的公式中误差较大,所以一般零件滚螺纹前,外圆毛坯尺寸常由试验确定,下面介绍一种较准确、迅速地确定该尺寸的方法,参见图1。 First, the general formula for the volume of thread deduction Machining, rolling the external thread blank size, the error introduced in some of the information in the larger error, so the general parts before the thread rolling, the outer ring rough size often determined by the test, the following describes a A more accurate and rapid method of determining this size is shown in Figure 1.
