Hot stamping forming process and stamping die

The invention relates to a hot stamping forming process and a stamping die, and the hot stamping forming process comprises the following steps: cutting a plate: cutting an original plate to obtain a to-be-stamped plate; preheating is conducted, specifically, the to-be-stamped plate is preheated; first-time stamping is conducted, specifically, the preheated to-be-stamped plate is placed in a stamping die, and first-time stamping is conducted on a first area of the to-be-stamped plate; and secondary stamping is conducted, specifically, secondary stamping is conducted on a second area of the to-be-stamped plate, and the first area does not coincide with the second area. Compared with a traditional single-time hot stamping process, the first area is subjected to first-time stamping, and then the second area is subjected to second-time stamping after first-time stamping forming, so that the pressure stress on the to-be-stamped plate is reasonably controlled, the tensile stress state can be achieved, the wrinkling
