ABSTRACT

Taking the plane flange drawing part as an example, the traditional forming process is mostly rigid drop forming in the early stage and artificial knock shaping in the later stage, so the qualified rate of the part is low in the forming process. It has a long production cycle, costs a lot of energy and other material resources, and the manufacturing cost is high. The application of the forming technology based on the combination of rigid and flexible in the forming process of such parts can effectively solve the problems existing in the traditional forming process of such parts, and effectively improve the surface quality of parts. By using DYNAFORM finite element analysis software to analyze the forming process of parts, we can accurately analyze the advantages and disadvantages of traditional rigid drop forming and rigid flexible combination forming process. Through the combination of rigid and flexible forming process, adjusting the pressure of flexible medium on parts and the size of blank holder gap in the forming process can solve the technical problems such as the rupture of flat flange drawing parts in the deformation stage, excessive local thinning and the surface quality of parts after forming not up to standard.
