Design and processing of the car models gate blanking die

Analyzed the structure and forming technology of the imported Benz Unimog car models gate. In order to improve the manufacturing efficiency, we reformed technologies in the traditional industrial production, such as mechanic, metal plate and studied the fractional-step forming stamping die of the car gate, in the reference of the cold stamping die. In this paper, we compared and analyzed the present cutting-edge technology " integrated molding technology" with fractional-step forming die technology, illustrated the principle of molding, the basic mold structure, molding stamping procedure for the cold stamping components and designed the typical stamping die. These designs include stretching blanking die, square hole perforation die, deviation hole perforation die, both ends bended die and the integrated bended die of the car models gate. In these designs, we made full use of the knowledge and resources we had and used the die design manual to design stamping die fleetly and make intensity checking.
