Effects of Contact Conditions at Wire–Die Interface on Temperature Distribution during Wire Drawing

The effects of contact conditions at the wire–die interface on temperature distribution specimen and die are investigated to understand wire drawing process. Finite element analysis experiments performed analyze a drawn based different using low-carbon steel wire. maximum (Tmax) decreases as heat transfer coefficient increases, whereas that increases with coefficient. Tmax thermal conductivity die. As generated by friction is rapidly absorbed into die, decreases, thus resulting in decrease surface both linearly factor. In particular, more sensitively changes factor compared velocity, parabolically velocity. influence bearing length increase insignificant.
