Abstract

With the promotion and application of high strength steel and hot stamping forming technology in automobile engineering, researchers gradually realize that in addition to improving the strength of automobile structural parts, the problem of matching the mechanical properties of parts and body safety requirements is also worthy of attention, that is, the same Different areas of the part actually have different mechanical properties requirements, that is, high-strength steel variable-strength hot stamping technology. For the B-pillar parts of the car, the upper part needs sufficient strength to ensure the integrity of the car body when the car is impacted, and the lower part needs good ductility to absorb energy, prevent collision and intrusion, and cause occupant harm. The realization of high-strength steel variable-strength hot-stamping process through special hot-stamping process has become a research hotspot. The main methods are differentiated initial temperature, different thermophysical mold materials, mold block heating, differentiated surface contact conditions and tempering processing.
