滚丝轮是现代螺纹生产中高效率的螺纹工具之一,它的材料是Cr12MoV;W18Cr4V;9CrSi等。其体积大用料多,制造工艺复杂,尤其反复锻造工序十分繁重。为了节省材料,物尽其用,可把废滚丝轮再次加工成新的滚丝轮。废旧滚丝轮翻新的理论根据和潜力滚丝轮是根据公式tgr=t件/πd_2=S/πD_2设计出来的,即πD_2/πd_2=S/t件=n。n就是滚丝轮的螺纹头数,也是滚丝轮的螺纹中径与被加工工件螺纹中径的比值。由此可见,滚丝轮的中径
Rolling wheel is a modern thread production of high efficiency thread tool, its material is Cr12MoV; W18Cr4V; 9CrSi and so on. Its bulky materials and more complex manufacturing processes, in particular, repeated forging process is very heavy. In order to save materials, make the best use of waste rollers can be re-processed into a new rolling wheel. The theoretical basis and potential of the rebuild of the used roller is that the roller is designed according to the formula tgr = t / πd_2 = S / πD 2, that is, πD_2 / πd_2 = S / t = n. n is the thread number of the thread rolling wheel, which is also the ratio of the thread diameter of the thread rolling wheel to the thread diameter of the thread to be machined. This shows that the diameter of the roller
