两异径圆柱管道接头及其展开

Connectors of Two Different Radi Cylindrical pipes and the Development of Connectors

利用圆锥曲面连接空间各种相对位置的两异径圆柱管道接头及其展开的问题。利用形数结合的计算方法,建立了管道接头的数学模型,设计了绘制展开图的通用程序。利用CAD的方法精确、简便和快速地解决了工程中常见的这一板金制件展开下料问题。

This paper describes how connectors joining two different radii Cylindrical pipes in various relative positions in space are made by cone and how connectors are devdoped. A mattre matical model of the connectors is established by algorithm method of graphic combining with calculation by means of projection and the general program is designed for the plotting of drawings of the development. Computer Aided Design can solve the common problems of development for cutting metal plate of workpieces in engineering precisely, conveniently and quickly.
