Hot stamping and quenching integrated treatment device and method

The invention discloses a hot stamping and quenching integrated treatment device and method, and belongs to the technical field of metal hot working. The device comprises a lower die mold surface core assembly composed of flexible small punches, a lower die is placed in a liquid pool, back pressure is provided and lifting is controlled through an ejector rod, and enough gaps exist between the small punches to allow liquid to freely flow; the blank is heated and subjected to heat preservation, so that the plate reaches the required temperature; then the blank is rapidly moved to the lower die; the blank is quickly formed under the action of the upper and lower dies; the upper die drives the lower die under the action of certain back pressure to continuously and quickly move downwards, so that the formed part is immersed in liquid to complete solid solution heat treatment; after the workpiece is cooled and shaped, the upper die moves upwards, the lower die stops moving upwards to the initial position, the upper
