Abstract: Expounded punching, blanking, bending modulus of the composite structure design and principle. Process analysis by the stamping of thinner material thickness small curved pieces, will use the punching, blanking, flexural modulus composites than continuous or Progressive Die simple. Punching through, the top pieces, such as the discharge of calculation to determine the type mold. The posterior mold using derivative-scale structures form. Waste from the punch and die and the base under which opened the tank discharges. The mold reliable, stable operation to adapt to the requirements of large-scale production, improve product quality and production efficiency. reduce labor intensity and the cost of production.
Keywords: Ramming; The punch holes, Fall the material curving; Superposable die
