Abstract: A method and die for a hot stamped member comprising a local soft region, and a hot stamped member, is provided. The method comprises moving an austenitized slab into a TTP thermoforming die, the TTP thermoforming die pressing out several ribs at a soft region position, moving a thermoformed member from the TTP thermoforming die into a shaping die, and pressing, when pressure is applied, the ribs of the soft region lower and wider until they are the same shape as a digital product model. A soft region is provided with ribs during thermoforming, and the ribs shrink during shaping to compensate for a dimensional change caused by the soft region cooling and shrinking, thereby not only ensuring the performance of a soft region of a part, but also solving the problems of severe dimensional deviation and poor dimensional stability after TTP formation.

A local region to be softened of a hot stamping blank is covered by a heat-insulating layer, and the heat-insulating layer is covered by a heating layer. After the hot stamping blank is fed into a heating furnace, a local temperature difference is generated, thereby forming a soft region. Then, the hot stamping blank having soft and hard regions is fed into a thermoforming machine so as to be machined into a hot stamped member. A hot stamping blank is subjected to local temperature control during heating to form a hot stamping blank having soft and hard regions, so that a hot stamped member that is locally softened can be formed in one step without the need for tailor welding. Therefore, die costs can be reduced, and the dimensional precision of obtained parts is high.
