摘要： 对超高强度防撞梁的热冲压成形过程进行了模拟分析,揭示了热成形过程不同阶段板料温度、厚度、微观组织和性能的变化规律,以及初始成形温度、冲压速度和压边力等工艺参数对超高强钢热成形的影响规律,优化了防撞梁热成形工艺参数,并通过试验进行了验证。结果表明:热冲压成形过程中,板料厚度变化主要发生在高速冲压阶段,微观组织及性能变化主要发生在淬火阶段,热冲压成形件卸载后的回弹量很小;初始成形温度对板料厚度变化影响显著,初始成形温度较低时板料成形性较差;冲压速度过大或过小均易导致板料减薄严重;添加压料板会大幅降低板料流动性,易导致拉裂;对本文构件而言,最佳工艺参数是:初始成形温度为800 ℃、冲压速度为100 mm/s,不设置压料板。

Abstract: The hot stamping process of an anti-collision beam with ultra high strength was analyzed by simulation. The evolutions of the temperature, thickness, microstructure and mechanical properties of the blank in different stages of hot stamping were investigated. The influences of the process parameters, such as initial forming temperature, punch speed and blankholder force, were studied. Then these parameters were optimized and the results were verified by hot stamping tests. Results show that the blank thickness varies mainly in the stamping stage, while the microstructure and the mechanical properties change mainly in the quenching stages, a little springback occurs after the component is unloaded. The influence of the initial forming temperature on the thickness is obvious, and the formability is poor under low initial forming temperature condition. Both over high and over low punch speeds can cause over reduction of the blank thickness. The blankholder setting reduces the fluidity of the metal greatly, which may bring in cracking. For the beam investigated in this work, the optimum process parameters are initial forming temperature of 800 ℃, punch speed of 100 mm/s, and no blankholder setting.

Key words: materials synthesis and processing technology, ultra high strength steel, hot stamping, process optimization, numerical simulation
