Research on the Hot Stamping of Invar Based on Flexible Mould

Abstract:

This paper introduces the defect formation and compensation method of Invar during hot stamping with multi point flexible mould. In cylindrical and spherical, for example, through Solidworks 3-d modeling, using Dynaform to do forming numerical simulation, we study multi point hot stamping defects of thick Invar, mainly including indentation and rebound. Then we get the rules of indentation and rebound with thickness and curvature, compensate these defects and control the error within the requirements.
