Abstract

In this study, we conducted an investigation into the multi-zone variable-strength hot stamping and forming technology within a single die. This investigation encompasses the crucial technologies of simulating and analyzing variable-strength (Tailored temperature process) hot stamping and forming, die design, part development, and testing. We have undertaken extensive research and development in these areas. The research involves analyzing part data and material requirements for simulating variable-strength hot stamping and forming, determining zoning requirements for mold design and development, and conducting trial production and testing of variable-strength hot stamping and forming parts. The simulation analysis includes hot stamping forming simulation analysis and forming simulation/mold temperature control and cooling analysis of the mold, with a focus on part data, material requirements, and part performance requirements. Additionally, we have developed a variable strength forming die and the associated heating and cooling system. Multiple batch prototyping with varying process conditions was carried out, and the fundamental mechanical properties of the parts were tested. Furthermore, the paper discusses the key aspects of material and processing development in the high-temperature zone of the variable strength forming die.
