油底壳的成型工艺与模具设计(含CAD图,ProE三维图)(任务书,开题报告,外文翻译,论文说明书16600字,CAD图纸16张,Pro/E三维图)
摘 要
这次设计的零件为汽车发动机油箱下底壳这一凸缘盒形件拉深件。此次设计的制件的外形是对称的，为了能够适用于制造高变形性能，深拉深产品及形状较复杂产品的钢材为材料的制件。首先，我们需要对零件的工艺进行分析，确定加工工序，有拉深（延）、冲孔、切边等一系列工序。而且油底壳要求大批量生产，并且各个工位上有一定的尺寸关系，经过我们的计算和分析，我们决定采用拉延与冲孔切边的工艺方案设计制造制件，因为这种方案能够提高材料的利用率。为了完成该模具的主要设计计算，我们需要对凸、凹模进行设计并且计算其数据，同时也要设计模具的工位布置，与此同时也要完成模具中必要的零部件的结构设计，并选择合适的模具材料，需要经过一系列的计算。拉深又称拉伸、压延或引深。拉深，就是我们设计制造的模具凭借着压力机给予的压力作用，将在拉深工序之前，已经被冲裁出一定形状的平面毛坯板料，加工成为立体的空心件的一种加工方法。拉延成型是毛胚板材立体成形的最主要的方式，非常多的冲压件以拉深成形为主体，现在有很多拉深成形的制品被利用在工业及生活用品中，这是冲模其中一种发展方向。
本次毕业设计需要对本专业学习的课程中的理论加以运用，同时也要求我们结合实际生产知识进行一次冲压模具设计，通过这次设计，可以养成和扩展学生独自工作的能力，而且，本次设计加深了学生对于本专业课程知识及老师教授的知识的理解，同时也额外学习了新的知识，熟悉了冲压模具设计的方法，了解了模具设计的步骤。在这次的设计中，我们了解到了如何对于对零件在制造时的工艺作出具体分析，要确定什么样加工工序方案，对于模具的结构有了基本的了解，使得我计算数据的能力提高了，熟练了二维、三维绘图软件的应用，对模具设计的规范和标准有了了解，同时，对于设计时用到的各个科目以及相关的知识都进一步的恢复和加强。
关 键 词：拉延模，拉深，切边，冲孔，设计。
The oil pan forming technology and die design
Abstract
The parts of the design for the flange box deep drawing parts, gasoline generator under the tank shell. The basic symmetry parts appearance, material is suitable for manufacturing high deformation performance, deep drawing steel and shape more complex products.
First on the parts manufacturability analysis, deep drawing, punching and trimming and a series of processes. And production batch is large, each station is the size of the relationship between each other, through calculation and analysis using a tensile trimming and punching process production plan, can improve the utilization rate of material. Through calculation and analysis to complete the main design and calculation of the mould, convex and concave mould work part of the design and calculation, and location layout and structural design of main components, choose the right mold material. Stretching also called drawing, rolling or drawing. It is the use of stretching die under the pressure of the press, will be cut in advance or cutting into a certain shape flat workpieces, pulled the three-dimensional hollow pieces of processing methods. Stretch forming is the most important plank three-dimensional forming method, to stretch forming as the main body of the stamping parts, in many industries and articles for daily use and stretch forming products, is one of the stamping die development direction.
This design is suitable for the production of such expertise and training practice a theory of cold stamping die design programs to develop and improve students' independent work, consolidate and expand the capacity of the course content, such as cold stamping die design, master cold stamping mold design methods and procedures, with cold stamping mold, a basic design skills, learn to analyze how technology components, how to determine treatment options, understand the basic structure of the mold, increase capacity, and drawing skills, familiar with specifications for all subjects and standards, and related courses have a comprehensive review, the ability to think independently improved.
Key words: tensile modulus, deep drawing, trimming, punching and design.
