The invention belongs to the technical field of hot stamping forming, and particularly relates to a plate hot stamping process. The plate hot stamping process comprises the following steps that platewashing is carried out, wherein a cleaning device is used for washing a plate to remove oil contaminations or dust; heating is carried out, wherein the washed plate is heated, and the plate is heatedin a walking beam furnace; after the plate is heated, the plate is rapidly transferred to a hot stamping die to be subjected to hot stamping forming; a formed part is rapidly cooled to 200 DEG C, anda martensitic structure is formed; and after the obtained part is cooled to 200 DEG C, the obtained part is cooled along with the room temperature, and a high-extension strength part is obtained. Theplate hot stamping process is mainly used for the process of the hot stamping process, and hot stamping hole forming is carried out on the plate; and the plate hot stamping process is used for carrying out hot stamping hole forming on the plate, cooling protection can be carried out on a plunger chip, the service life of the plunger chip is prolonged, and in addition, in the plate conveying process, scratches of the plate are reduced.
