Abstract: |
The article introduces process flow, engineer testing condition and testing process of small diameter and large length diameter ratio thin-wall cylinder’s spinning which is processed with steel tube billet. It studies the way of different technological parameter’s influences on small diameter thin-wall cylinder’s spinning by large diameter spinning roller synchronous backward spinning. It solves the key problem of spinning course, such as bulged instability, wrinkled on billet, linearity out of tolerance seriously after spinning precisely, unloading difficultly and so on. It also pledges products’ precision, so as to provide reference for similar spinning. |
