Abstract

Closed-open cross wedge rolling(CWR) is a kind of advanced precision forming technology, which can effectively reduce or even eliminate the concave. The workpiece is processed from the shaft end to the middle by the rolls first, and then machined by open CWR. An auto pump shaft is taken as the research object. A 3D coupling thermal, mechanical, microstructural finite element model is established by the finite element analysis software DEFORM-3D according to the constitutive equation and microstructure evolvement model of 42CrMo. Distribution laws of temperature field and microstructure field are acquired. This work not only lays a theoretical foundation for improving the product quality and the comprehensive performance of rolled piece, but also provides a guideline for further application and extension of closed-open CWR.
