针对某车型前防撞梁零件开发热成形模具，并进行热冲压成形试验，对成形后的零件进行激光扫描以及金相组织、显微硬度和力学性能检测。结果表明：所试制的零件形状符合设计要求，热成形后零件为马氏体组织，显微硬度在HV400 以上，样件屈服强度在1 000 MPa以上，抗拉强度在1 400 MPa以上，断后延伸率在10 %以上。

Based on the front bumper of a commercial vehicle，the hot stamping mould was developed，and the hot stamping experiment was carried out. The laser scanning，microstructure， microhardness and mechanical properties of the components were detected. The results showed that the shape of the components meets the design requirements；the structure of components after hot stamping is martensite structure；the hardness of the components is more than HV400； the yield strength of the components is more than 1 000 MPa；the tensile strength of the components is more than 1 400 MPa；the elongation exceeds 10 %.
