Because the automobile manufacturers require a thick wall steel pipe diameter and length is not the same as the need for custom,,
The tensile strength of hot stamping technology is a new technology for ultra high strength steel plate forming. The tensile strength of the hot stamping can be more than 1500MPa, and high forming precision, no rebound. This way can make full use of the plasticity of material properties for stamping parts, auto parts manufacturing, can improve the safety performance the car, reducing body weight. At present, only a few units of hot stamping technology in the mold design, process test and simulation to obtain the corresponding results, but the relationship between process parameters is not an in-depth discussion of hot stamping process. It is difficult to grasp, the use of simulation technology can optimize the process parameters. At the door anticollision beam as an example, the process characteristics of the combination of research methods through numerical simulation and hot stamping test of ultra high strength steel hot stamping, punching and stamping speed and pressure to establish initial forming temperature The relationship between the model and the correctness of the model is verified by experiment. The test steel material properties for Baosteel 22MnB5 hot rolled plate, the number is BR1500HS, thickness of 2mm, density of 7850kg/m3, the critical cooling rate is 15 DEG /s, the chemical composition of BR1500HS% S mass fraction of P elements C Mn B Si Cr 0.21 1.35 0.0033 0.28 0.23 0.004 0.0055 hot rolling state, the hardness of the material is about 193HV, the tensile strength is 500 ~ 600MPa
The vehicle door anti-collision rodPerformance:
Before quenching yield strength more than 300MPa, the tensile strength is more than 600MPa;
After quenching, the yield strength is more than 1200MPa, the tensile strength is more than 1500MPa;
