汽车车身铝合金板材热冲压模内淬火工艺技术

Heat treatment,forming and in-die quenching process used on aluminum alloy sheet pressing

热冲压成形及模内淬火工艺(HFO)是一种针对于复杂冲压形状的高强度铝合金板材的先进生产工艺方法,可以提升高强度铝合金板材的冲压性能,同时又避免了热成形后的材料性能严重下降,可大规模提升铝材料的应用在轻量化车身中所占比重,对于汽车轻量化开发具有很重要的研发价值。对HFQ工艺流程、在汽车上的应用以及目前的研发进展进行了系统的介绍。

Heat treatment,forming and in- die quenching process（ HFQ） is a production method for stamping complex- shaped aluminium components from high- strength and ultra- high- strength alloys. HFQ can improve the formability of high- strength aluminium alloys and avoid the reducing of material performance. HFQ can be used to enhance the application of aluminum materials in lightweight body,and it is important to the development of lightweight vehicle. Presents HFQ process and it＇s application in the automotive,and the current development.
