摘 要

本文分析了电咖啡壶的发展现状与趋势，提出了电咖啡壶的发展应倾向于外观设计的建议。Pro/E是参数化技术最早应用者，而Creo是一个整合Pro/ENGINEER、CoCreate和ProductView三大软件并重新分发的新型CAD设计软件包，针对不同的任务应用将采用更为简单化子应用的方式，所有子应用采用统一的文件格式。AutoCAD是用于二维绘图、详细绘制、设计文档和基本三维设计的自动计算机辅助设计软件，可以用于土木建筑、装饰装潢、工业制图、工程制图、电子工业等多方面领域。Pro/E、Creo和AutoCAD是现今主流的CAD/CAM/CAE软件之一，特别是在国内产品设计领域占据重要位置。本文采用了Pro/E和Creo三维软件对电咖啡壶进行了三维建模和模具设计。对电咖啡壶的外形设计主要做了咖啡壶体、加热底座、漏斗、手柄的设计，然后对这些电咖啡壶的零件进行了虚拟装配，使用AutoCAD做出装配总图和部分零件图。装配完成后对电咖啡壶的加热底座进行了模具设计。本次的重点在于通过对电咖啡壶的设计完成对Pro/E、Creo和AutoCAD的基本特征的掌握。

Modeling design of electric coffee maker

ABSTRACT

This paper analyzes the current situation and development trend of electric coffee pot, and puts forward the suggestion that the development of electric coffee pot should be inclined to the appearance design. Pro / E is the first application of Parametric Technology，Creo is a new CAD design package that integrates Pro/ENGINEER、CoCreate and ProductView three software and distributes it, for different tasks, applications will adopt a more simplistic child application, and all applications will adopt a unified file format. AutoCAD is used for 2D drawing, detail drawing, automatic computer aided design software design documentation and basic 3D design, can be used in the civil construction, decoration industry, drawing, engineering drawing, electronic industry and so on. Pro/E、Creo and AutoCAD are now the mainstream, especially in the field of domestic product design occupies an important position. In this paper, 3D modeling and die design of electric coffee pot are made by using Pro/E and Creo software. The main design of the electric coffee pot is made of a coffee pot, a heating base, a funnel and a handle. Then, the components of these electric coffee pots are assembled by virtual, and the assembly drawings and parts drawings are made by using AutoCAD. After finishing the assembly, the mold design of the heating base of the electric coffee pot is carried out. The emphasis here is on the mastery of the basic features of the Pro/E、Creo and AutoCAD through the design of the electric coffee maker.

Key words：Electric coffee maker; Creo; Modeling design
