Abstract
Box-shaped pieces in the process of drawing the material deformation is rather complicated. Wrinkling and the breakdown of its drawing in the main form of failure, and its impact on the quality of forming the major factor is the BHF, the mechanical properties of materials, drawing die parameters, friction conditions and slab shape and thickness. At present, although the rectangular box in the shape of the theoretical analysis and experimental research done a lot of work, but because of the complexity of the deformation, not as Cylindrical parts and pieces as a square box that is more mature theory analysis . With the finite element software and computer technology not to develop, design and manufacture of the mold, can be used finite element analysis, simulation stamping process, the process of drawing forecast may have wrinkles and break down, stamping parts in time to amend the structure size shape Bring it into line with stamping parts of the stamping process. Rectangular pieces of molding to make the laws of numerical simulation possible. In this paper, ZW32-16 outdoor column vacuum circuit breaker box as an example, discussed focused on the rough play in the process pull deep hole method, finite element analysis, testing whether this method of drawing to improve performance Has positive significance. The establishment of products from the model and finite element analysis, respectively, from the stress and strain, and other aspects of analysis and this analysis, design and manufacture die as the theoretical basis and can shorten the vacuum circuit breaker box product development cycle and reduce production costs .
