Analysis of thread rolling die and its application on automatical screwmachine

摘要

For the current thread rolling die widely used and introduce material less, analyse design process of thread rolling die and introduce the methods how to determine the parameters combined with cold rolling principles. At the same time, point out the methods that prevent thread rolling die prematurely failure. Thus, lay a solid theoretical foundation for the design and manufacture of thread rolling die. Meanwhile, do a simple introduction for its application on the automatical screwmachine.
