图1所示为某厂出口产品上所用的特殊梯形双头螺纹零件,由于批量大,该工艺规定用滚丝轮进行滚压加工。因此滚丝轮无现货供应,经分析研究,为该厂设计制造了滚丝轮。现将滚丝轮的设计介绍如下。众所周知,利用滚丝轮可以进行单头螺纹的滚压加工,能否利用滚丝轮滚压双头螺纹呢?这方面我厂 Figure 1 shows the special trapezoidal double-headed threaded parts used in the export of a factory. Due to the large batch size, the process stipulates that the rolling process be performed by a rolling wheel. Therefore, there is no stock roller gear, the analysis of research, design and manufacture of the plant rolling wheel. Now the design of rolling wheel is as follows. As we all know, the use of rolling wheel can be single-head thread rolling process, the use of rolling wheel rolling double-headed thread? In this regard, I plant
