Title Stamping die design and forming simulation of the Automobile parts
Abstract
Many structure parts of automobile are sheet metal parts, this topic researches on designing a stamping die and forming simulation of the automobile parts. First complete automobile structural parts of the stamping process design, using the DYNAFORM software to simulate and analyze the molding process, accurate prediction the forming process, Thickness variation, strain of sheet metal, so as to provide the best plan for die design. Second, using the Pro/E software to design the punch and die, positioning device and discharge device structure, complete the whole mold assembly. considering to the automobile structural parts of the shape, size, technical requirements, error and Simulation of forming parameters, and according to the basic steps of mold design and reference design standard to finish all the design of automobile parts stamping die. Finally, draw the general assembly drawing and parts of engineering drawings.
