落料拉深復合模具设计.doc

摘 要 随着现代工业的发展和人们的生活不断改善，各种新型的工具不断地问世为人们的生活提供方便，而在制造这些工具的过程离不开模具。各种模具在不同的时代发生着飞跃的变化，随之出现许多不同的制造方式。 由于产品的材料和工艺特性不同，生产用的设备也各异，模具种类繁多，但用的最为广泛的大约有以下几种：冷冲压模、塑料成型模、锻造模、精密铸造模、粉末冶金模、橡胶成型模、玻璃成型模、窑业制品模、食品糖果模、建材用模等。其中以冷冲压模、塑料模的技术要求和复杂程度较高。 我的设计课题是：内胆的拉深，主要介绍的是无凸缘筒形件拉深模的设计过程。我参考了大量有关拉深模模具设计实例等方面的资料。拉深是利用拉深模将板料制成各种空心件的一种方法，是冲压生产中应用最主要的工序之一。我设计的是无凸缘内胆拉深模设计和制造，材料为08钢板，厚度t=2mm。采用的工序为落料拉深复合工序和拉深单工。设计的主要内容：工件的工艺性分析；冲压工艺方案的确定；模具的技术要求及材料选用；主要设计尺寸的计算；工作部分尺寸计算；模具的总体设计；主要零部件的结构设计；模具的总装图；模具的装配等。最后生成装配工程图和相关的零件图。 关键词：模具 落料 拉深 装配图 零件图 Abstract With the development of modern industry and peoples lives continue to improve, a variety of new tools continue to come out to provide convenience to peoples lives and in the process of manufacture of these tools can not be separated from the mold. Various molds at different times, changes in the leap, followed by a number of different manufacturing methods. Materials and workmanship of the product characteristics, production equipment also vary a wide range of mold, but the most widely used in approximately the following: cold stamping mold, plastic molding, forging mold, the mold of precision casting, powder metallurgy mold, rubber molding, glass molding, ceramic products, mold, food candy mold, building materials and mold. Among them, the high technical requirements and complexity of the cold stamping mold, plastic mold. In the design, introduces the mold drawing. In this design, I made reference to the large number of Die mold design example. The drawing is a drawing die as a processing method of the sheet metal stamping into a variety of hollow, is the most widely used in the stamping process. I designed the interior of no flange drawing die design and manufacturing materials for the steel plate 08, the thickness t = 1mm. Processing methods for the blanking pull deep composite processes and drawing a single process. Processing method is relatively simple. The main content of the design: the process of the workpiece analysis; prog
