Thermo-mechanical coupled analysis of hot stamping process for square cup component
Hot stamping is an innovative manufacturing process for forming of high strength steels, which is a non-isothermal process in which a sheet at austenite temperature is rapidly cooled down and formed into a die at the same time. This forming process is a new way to manufacture complex-shaped component such as automobile structural component with tensile strength of up to 1,500MPa, thus enabling extensive cost savings and good crash performance. Better formability at elevated temperatures and lower springback are further advantages of components formed by hot stamping. The finite element analysis is indispensable for a good process design including all process parameters. A 3D elastic-plastic coupled thermo-mechanical FE model for hot stamping of square cup component was developed in this paper based on ABAQUS 3D software by means of experimentally calculated material data and the model was used to describe a number of procedures for the simulation of hot stamping. The coupled heat transferring, material thining ratio and temperature distribution on the square cup component were simulated and the effects of process parameters on them were analyzed. The appropriate process parameters have been achieved by simulations, and the simulations were verified by experiment results.
