热冲压技术由于具有成形性好、低的成形力、回弹小以及零件强度高等优点被广泛应用于汽车工业,但随着汽 车对于减重和安全性的进一步提高,单一高强度的热冲压零件已经不能满足碰撞吸能需求,文章提出将某车型 B 柱、A 柱、门
槛和 A 柱下加强板四个零件合并得到包含两种厚度规格的一体式热冲压门环零件,在降低整车重量的同时提升了碰撞性能。针 对零件合并造成的成形性问题,基于 CAE 分析技术,对门环零件结构进行了优化设计,在满足成形性的同时,零件最终的力学 性能亦满足要求。通过增大局部圆角的方式可以有效降低热冲压后零件的减薄率,保证整体的强度和刚度,通过增设吸皱包或 台阶的方式可以有效解决起皱叠料现象,同时减薄率也在可控范围内,满足设计需求。

The hot stamping technology is widely used in automobile industry because of its advantages of good formability, lower
forming force, small springback and high part strength. However, with the further improvement of automobile weight reduction and safety,
single high-strength hot stamping parts can no longer meet the energy absorption requirements of collision.This paper proposes to combine
four parts of B-pillar, A-pillar, threshold and lower A-pillar reinforcement plate to the integrated hot stamping door ring parts with two
thickness specifications, it can reduce the vehicle weight and improve the collision performance. The combination of parts will cause
formability problems. Based on CAE analysis technology, the structure of the door knocker part is optimized, which can meet the
formability and the final mechanical properties of the parts. By increasing the local fillet, the thinning rate of hot stamping parts can be
effectively reduced, and the overall strength and stiffness can be ensured. The wrinkle stacking phenomenon can be effectively solved by
adding wrinkle absorbing bags or steps. At the same time, the thinning rate is within the controllable range to meet the design requirements.
