【摘要】 磁极冲片是水轮发电机的重要组成零件，其主要由复式冲模冲裁而成。随着工厂的发展，生产方面对其各项性能的要求不断提高。为降低模具制造成本，缩短模具制造周期，降低模具设计的工作量，同时基于磁极冲片具有结构相对固定但系列较多的特点，对磁极冲片复式冲模进行参数化设计系统的开发具有迫切需求。本文主要从以下几个方面进行研究和探讨：完成了系统总体的结构、功能、流程设计；针对零件种类多但是构型基本固定的特点，研究了模块化建模方法；通过结合复式冲模的实际问题，开发了UG集成应用程序；研究了参数化设计的关键算法：将空间坐标变换在复式冲模装配过程中进行了应用；研究三种目标边定位搜索算法，对其进行比较并得出最佳算法，并将其用于目标对象的定位，实现了后台特征造型的准确定位；研究了几何约束法，并对原有的几何对象进行重新定义，扩大了范围，提高了效率。研究了图形布置算法，实现二维工程图在自动绘制时避免图纸中的多个视图可能发生干涉或重叠问题。最后，选择UG NX6.0和VS2010作为开发平台，应用上述关键技术开发了磁极冲片复式冲模参数化设计系统。采用模块化思想，开发了复式冲模零件的三维参数化建模和装配，可实现不同构型，不同参数的磁极三维模型的自动建模和装配；根据三维模型获得的构型尺寸快速建立符合企业技术标准的二维工程图，实现磁极冲片复式冲模从三维模型到二维工程图纸的全自动生成。更多还原

【Abstract】 Punching sheet with magnetic pole is an important part of hydro-generator,which consist of compound die and punching. With the development of factories,the demand on its quality is becoming more and more high.In order to achieve lowercost of manufacturing, shorter manufacturing cycle time and less workload of diedesign, finding a kind of design method which can implement parametric design oncompound die of punching sheet with magnetic pole is urgent.This thesis did some research work as follows:The design on structure, function and process of system is done. Given thatthere are many kinds of parts, but their structures are similar, modular designmethod is proposed. Considering the actual problems of compound die, theintegrated program of UG software is developed.The key algorithm of parametric design is researched. Space coordinate istransformed and then is used in assemble of compound die. This thesis proposedthree algorithm for side location and searching, and found the optimal algorithm,then it is used in location of target, at last the precise location of feature modeling isrealized. Geometric constraint method is researched, and the original geometrictarget is redefined, which enlarge the range and improve the efficiency. Thealgorithm of graphics arrangement is researched, the problem that view interferenceand overlap might happen during automatic drawing.At last, the parametric design system of punching sheet with magnetic pole isdeveloped with the platform of UG NX6.0and VS2010. With modular idea, threedimensional modeling and assemble method of compound die parts are proposed,which realized automatic modeling and assemble on magnetic poles with differentstructures and parameters. According to the structure size, standard engineeringdrawing can be obtained, which means3d and2d engineering drawing of magneticpole with compound die can be drew automatically.更多还原
