摘要：本次设计了一套冲孔﹑弯曲切断的模具。经过查阅资料，首先要对零件进行工艺分析，经过工艺分析和对比，采用冲孔弯曲切断工序，通过冲裁力、顶件力、卸料力等计算，确定模具的类型。得出将设计的模具类型后将模具的各工作零部件设计过程表达出来。
在论文中第一部分，主要叙述了冲压模具的发展状况，说明了冲压模具的重要性，接着是对冲压件的工艺分析，完成了工艺方案的确定。第二部分，对零件排样图的设计，完成了材料利用率的计算。再进行冲裁工艺力的计算和冲裁模工作部分的设计计算，对选择冲压设备提供依据。最后对主要零部件的设计和标准件的选择，为本次设计模具的绘制和模具的成形提供依据。通过前面的设计方案画出模具各零件图和装配图。6891
本模具性能可靠，运行平稳，能够适应大批量生产要求，提高了产品质量和生产效率，降低劳动强度和生产成本。

Design of the progressive die of the Cable box
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, completed 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 large-scale production, improve product quality and production efficiency. reduce labor intensity and the cost of production.
