毕业论文—铭牌底板生产技术设计.docVIP

湖北理工学院 毕业论文（论文） 摘 要 冲压工艺技术具有生产效率高、生产成本低、材料利用率高、能成形复杂零件、适合大批量生产等优点。本文简单的介绍了复合冲压模，研究了冲压成形的基本理论,然后运用基本理论对该制件的基本工序的特点、性质、规律进行了分析、研究和探讨。以冲孔、落料工序为重点确定冲压工艺方案，决定采取倒装复合冲压模。在制件的整体结构的设计中，还要进行模具中各个零件的设计及选择和某些零件相关尺寸的计算及校核，如确定凹模尺寸、凸模尺寸，确定凸、凹模的结构形式，并对其进行强度校核。然后是模具的零件设计，主要是导柱、导套的设计选择，卸料板的选择及其厚度的确定，固定板的尺寸确定。确定模具上下模座的形式及其厚度，最终完成了给定的铭牌底板工件的制作。 关键字：冲压；复合模；高效率 ABSTRACT Stamping technology has the advantages of high production efficiency,low production cost,highutilization ratio of material, forming advantages of complex parts,suitable for mass production. This paper describes a simple compound stamping die, the basic theory of stamping forming, and then use the basic theory of the parts of the basic process,characteristics, nature of law are analyzed, studied and discussed. In order to punching, blanking process to determine the stamping process scheme for the key, decided to flip composite stamping die.In the design of the whole structure of parts of the calculation and checking, but also for the design and selection of various parts in the mold and some parts size, such as determining the size of female die, punch size, determine the structure form, the concave and convex, and check the strength of the. Then the design of mold, is mainly the design guide column, a guide sleeve selection, selection and the thickness of the fixing plate stripper plate, the size determination.Determine the form and the thickness of die holder die, finally completed the nameplate of the given floor workpiece.
