摘要
基于 Active X技术 ,运用 VBA,对复杂铝型材挤压分流模 CAD的关键技术进行了研究。系统分解为挤压模工艺参数和模具结构设计二大模块 ,利用区域法自动查找型材质心和最大外接圆直径。提出了最短工作带位置的自动寻找方法和工作带的 CAD计算公式。采用交互式设计 ,模块化程度高 ,易于维护和扩充。
Based on Active X technology,the CAD key technology of the complicated extrusion porthole die of aluminium profiles is studied by VBA The system consists of extrusion die process parameters and die structure design,and the centroid and the maximum diameter of circumcircle can be found out automatically The position of the shortest die bearing is investigated The design can be carried out interactively and it is highly modularized The system is easy to be maintained and extended
