Abstract
The utility model discloses a forming blanking composite die without a forming female die. The forming blanking composite die comprises an upper die and a lower die, the upper die comprises an upper die base and a male die. The male die is fixed to the upper die base through a fixing plate, a discharging plate is further connected to the upper die base in a sliding mode through a discharging screw, and a spring is further arranged between the discharging plate and the upper die base. A guide sleeve is further arranged on the upper die base. The lower die comprises a blanking female die and a lower die base, the upper surface of the blanking female die is matched with the discharging plate, and a female die cutting edge of the blanking female die is matched with the male die. A guide pillar seat and a guide pillar are arranged on the lower die holder, and the guide pillar is in guide fit with the guide sleeve; and a material receiving box is arranged below the material leakage hole of the blanking female die. According to the structure, a process supplement molded surface required by an original forming blanking progressive die structure is removed, so that the material utilization rate is improved. According to the structure, forming and blanking are combined in one die cavity, so that manual operation is more convenient, the production takt is shortened, and the production efficiency is greatly improved.
