毕业论文油箱下壳体冲压模具设计说明书.doc

摘要
本次设计的零件为凸缘盒形件拉深件—油箱下壳体。。该零件外形基本对称,材料是适于制造高变形性能,深拉延产品及形状较复杂产品的钢材。
首先对零件进行了工艺性分析,有拉深、冲孔、切边等一系列工序。而且生产批量大,各工位有相互的尺寸关系,经过计算分析采用一次拉深与冲孔切边的工艺生产方案,可提高材料的利用率。经过计算分析完成该模具的主要设计计算,凸、凹模工作部分的设计计算,还有工位布置和主要零部件的结构设计,选择合适的模具材料。拉深又称拉延、压延或引伸。它是利用拉深模具在压力机的压力作用下,将预先剪裁或冲裁成一定形状的平板毛坯,拉制成立体空心件的加工方法。拉深成形是板材立体成形的最重要方法,以拉深成形为主体的冲压件非常多,在很多工业及生活用品中都又拉深成形的制品,是冲模发展方向之一。在模具设计前必须对工件进行全面分析,然后合理确定工件的冲压成形工艺方案,正确设计模具结构和模具零件的加工工艺规程,以获得最佳的技术经济效益。

Abstract
The design of box-shaped flange parts for deep drawing parts - gasoline generator under the tank shell. Shell material used under No. ST16 steel and thickness to ensure sufficient strength and stiffness. This deformation of material is suitable for manufacturing high-performance and deep-drawing products and plex products shape.
We carried out the parts of analysis, there is deep drawing, punching, cutting-edge series of processes. And production volume, and the works are of the size of the mutual relationship between the calculated and analyzed through the use of a stretching and punching the production of cutting-edge technology options to improve the utilization of materials. pletion of the analysis of the mold design,convex and concave die part of the design work,there are the ponents of layout and design of the structure, choose a suitable mold material.
Also known as tensile drawing, rolling or extended. It is stretching the use of molds in the press under pressure, will be pre-cut or blanking plate into the shape of a certain rough, three-dimensional drawing made of hollow pieces of processing methods. It is stretching the use of molds in the press under pressure, will be pre-cut or blanking plate into the shape of a certain rough, three-dimensional drawing made of hollow pieces of processing methods. Prior the design of the die, the work-piece should be fully analysis. A correctly designed die structure and works process specifications can obtain the best economical benefit.
