【正文】 地位正日趨上升?，F(xiàn)代制造工業(yè)的發(fā)展和技術水平地提高，在很大程度上取決于模具工業(yè)的發(fā)展。模具工業(yè)是國民經(jīng)濟的基礎工業(yè)。 關鍵詞 ：沖壓 ， 落料沖孔模 ， 模具結構 II Title: Round gasket stamping process with missing and die design Major: Materials Science and Engineering Name: Dan Zhao Signature: Supervisor: YuJun Zhang Signature: ABSTRACT A molding tool for designing a set only hurtling bore falling anticipating. After a lot of access to information, Punching and blanking procedure were adopted through process analysis, punching through, the top pieces, such as the discharge of calculation to determine the type mold. Get a molding tool for will designing type empress expresses out each work zero parts design process of the molding tool. In the first part, mainly described the development status of progressive metal stamping tools, illustrates the importance of stamping mould, then there is the process analysis of stamping process scheme, pleted the sure. Further blanking force calculation and Die Design and calculation of working part .provide the basis for the selection of stamping equipment. Finally on the main parts design and standard for the selection of design, mould of plotting and die forming provides the basis. The design project passing before draws an each spare parts of molding tool diagram with assemble the diagram. The mold reliable, stable operation to adapt to the requirements of largescale production, improve product quality and production efficiency. Reduce labor intensity and the cost of production.
