高维锥体拉伸中变锥角的变化cad

摘要
本文介绍的模具实例结构简单实用，使用方便可靠，主要说明的是在零件被拉伸时考虑到材料的流动性及摩擦还有塑性变形等的综合因素对变锥角产生的影响。当所有的参数计算完后，对磨具的装配方案，对主要零件的设计和装配要求技术要求都进行了分析。在设计过程中除了设计说明书外，还包括模具的装配图，非标准零件的零件图，工件的加工工艺卡片，工艺规程卡片，非标准零件的加工工艺过程卡片。
此次设计就是在UG平台上对固拉伸模具设计及动画演示。在设计过程中，通过了解和掌握冲压模具材料及拉伸模设计的有关知识，主要完成了模具的工作零件、定位零件、导向零件和装配零件的设计，并利用UG软件三维造型及工作过程的动画设计。
通过设计，不仅掌握了冲压模具的基本设计过程和设计要领，并了解了冲压模具的成型原理，以及UG软件的实体建模、装配建模、制图基础、工作过程动画设计等各个环节的基本操作规则

Abstract
This article describes the structure of the mold is simple and practical examples and easy to use and reliable, the main parts that is taken into account by stretching the flow of material and friction there is plastic deformation of a combination of factors, such as changing the impact angle. When all the parameters after the assembly program of the abrasive, the main parts of the design and assembly requirements of the technical requirements were analyzed. In addition during the design process, design specification, but also including the mold assembly drawing, parts of non-standard parts diagram, workpiece processing card, the card order process, non-standard parts of the process of card processing technology.
The design is the platform of UG solid tensile mold design and animation presentation. During the design process, through understanding and knowledge of stamping die design of materials and tensile modulus of the relevant knowledge, the main work of the completion of the mold parts, positioning parts, spare parts and assembly-oriented design of parts and the use of UG and the work of three-dimensional modeling software process animation.
Through the design, not only mastered basic stamping die design process and design essentials, which is under the principle of stamping die of the molding, as well as the UG software, solid modeling, assembly modeling, mapping the basis of the design process all aspects of animation of the basic operation Rules

Keywords　Stamping die;Tensile; Variable cone angle;UG
