Patent ID: 8631678

Claim:
A stamping die, comprising: a lower die; an upper die; a working position limiter; and a rigid storing limiter, wherein the lower die and the upper die are connected via a guide pillar for direction-guiding, so that the lower die and the upper die are movable relatively, and the working position limiter and the rigid storing limiter are arranged between the lower die and the upper die, wherein, the stamping die further comprises at least one elastic storing limiter arranged between the upper die and the lower die, a rigid storing limiter storing hole for containing the rigid storing limiter is arranged on the lower die, a boss is provided at a lower end of the rigid storing limiter, and a diameter of the rigid storing limiter storing hole is smaller than a diameter of the boss of the rigid storing limiter and is larger than a diameter of an upper portion of the rigid storing limiter, and in a storing state of the stamping die, the rigid storing limiter is placed on the rigid storing limiter storing hole, with the boss abutting an upper surface of the lower die, and a distance from an end, away from the lower die, of the rigid storing limiter to the upper surface of the lower die is larger than a distance from a top end of the working position limiter to the upper surface of the lower die; and in a working state of the stamping die, the rigid storing limiter is turned over, with the upper portion being inserted in the rigid storing limiter storing hole, and a distance from an end, away from the lower die, of the rigid storing limiter to the upper surface of the lower die is smaller than the distance from the top end of the working position limiter to the upper surface of the lower die.
