Ultra-High Strength Steel Hot Stamping Technology and Devices

摘要：

　　Ultra High Strength Steel (UHSS) hot stamping technology is a special process which can enhance the steel tensile strength to 1500MPa.Appling this technology in producing vehicle structure parts can make car lighter and safer.In China there are more and more automobile enterprises adopt this technology.To master and extend the skill, China Academy of Machinery Science & Technology (CAM) have done systematic research, such as the strengthen mechanism of the steel, hot stamping key devices designing, forming and quenching integrated mould designing,stamping process parameters optimization, etc..By now, CAM has mastered the mass production technology of vehicle pans, which can guarantee its size and tensile strength, and made some typical parts like door-beam, B pillar, etc..Especially in mould manufacture area, proposed a new method which is presetting the internal cooling pipe (ICP) in the cavity of sand mold and then pouting the molten metal (hereinafter referred to as CPP, Casting with Preset Pipe).The paper is an introduction of the research work and achievement about UHSS hot stamping developed by CAM.
