冷却通道对超高强度钢热成形过程温度场的影响

摘要

采用ABAQUS对槽型件热冲压成形过程进行模拟；通过改变模具冷却通道的结构参数，研究冷却通道对板料温度场的影响。结果表明：为保证板料的冷却效果，冷却通道直径、冷却通道距模具表面的距离都不宜过大；板料的冷却效果也并不是冷却通道间壁厚越小越好。%This paper use ABAQUS to do model test for the forming process of hot stamping groove parts,through changing the molding cooling down structure parameter to study how the cooling down channel influences the sheet metal temperature.The results showed that to make sure the cooling effect of sheet metal,the cooling channel diameter,distance between cooling channel from the mold surface should not be too large;the cooling effect of sheet metal is not that with the cooling channel wall thickness smaller is better.
