The first upper die 110 is provided at a lower side thereof with a first punch 111, and the first punch 111 punches out a thin-walled product to form an inner contour of a hollow pattern. The first lower mold 120 is provided with a first bearing part 121 and a first positioning column 122, the first bearing part 121 is used for bearing a thin-walled product, so that the thin-walled product can be smoothly placed on the surface of the first bearing part 121 on the upper side of the first lower mold 120; the first positioning column 122 is used for penetrating through the hollow pattern inner cavity of the thin-wall product to position the thin-wall product, so that the first punch 111 can accurately punch out the inner contour of other hollow patterns on the thin-wall product.
As shown in fig. 1, the first lower mold 120 is fixedly disposed. The first lower mold 120 has a first bearing portion 121 formed on an upper surface thereof for bearing a thin-walled product. Specifically, in this embodiment, the punching die set is suitable for thin-walled products that are revolving bodies, and for the convenience, the thin-walled products that are revolving bodies are reliably supported and limited, and the thin-walled products are prevented from deforming. In this embodiment, the first bearing portion 121 has an arc structure corresponding to a thin-walled product. It is understood that the radius of the cambered surface structure of the first bearing part 121 can be smaller than or equal to the radius of the thin-walled product, but cannot be significantly larger than the radius of the thin-walled product. In other embodiments different from the present embodiment, the shape of the first bearing part 121 may be correspondingly configured according to the specific shape of the thin-walled product, including but not limited to a plane shape, a folded line shape, and the like.
