摘要

PPROBLEM TO BE SOLVED: To achieve both of securement of high formability of an Al-Mg-Si-based aluminum alloy sheet mainly used as an automotive body sheet and keeping of high productivity in the forming. PSOLUTION: Regarding the Al-Mg-Si-based aluminum alloy sheet lying in a sub-aged state by age hardening or in a worked and hardened state by rolling, before cold press forming therefor, solution heat treatment is partially performed, a strength difference is imparted to a heated part and a non-heated part, and the heated part having low strength is made to abut on the pressure pad part, and the non-heated part having high strength is made to abut on a punch shoulder part, thus cold press forming is performed. In the partial solution heat treatment, rapid cooling is performed at 50C/min in such a manner that the heating arrival temperature of the heated part is controlled to 480 to 580C.

要解决的问题：为了确保主要用作汽车车身板的Al-Mg-Si基铝合金板的高可成形性，并保持成形的高生产率。

解决方案：关于通过时效硬化处于亚时效状态或通过轧制而处于加工和硬化状态的Al-Mg-Si基铝合金薄板，在对其进行冷压成形之前，先对其进行固溶热处理，在加热部和非加热部施加强度差，使强度低的加热部抵接在压垫部上，使强度高的非加热部抵接在凸模肩上零件，因此执行冷压成型。在部分固溶热处理中，以将被加热部的加热到达温度控制为480〜＜580℃的方式，以50℃/ min的速度进行快速冷却。
