The hot stamping forming technology heats the boron steel plate (initial strength 500-700 MPa) to the austenitizing state, and quickly transfers it to the high-speed press forming in the mold. Under the condition of ensuring a certain pressure, the workpiece is in the mold body. The quenching treatment is performed at a cooling rate of more than 27 ° C / s, and the quenching is performed for a while to obtain a forming method of ultra-high strength steel parts having a uniform martensite structure.
Hot stamping forming technology is divided into direct thermoforming and indirect thermoforming.
