挤压模具设计综合数据库系统

采用结构化程序和规范化数据库技术，开发了模具设计综合数据库系统，该系统由6个设计模块，即棒材模、实心型材模、空心型材模、壁板模、宽展模、导流模设计模块和1个系统维护模块组成，可以构成挤压模具设计专家系统重要的专家经验来源和实现自学习、自积累的支撑体系，也可以作为独立的软件使用，完成模具设计过程中的经验积累与数据积累，代替挤压模具设计技术资料手册，实现相关设计参数的自动计算和模具强度校核，利用该系统可以大大减轻技术人员的劳动工作量，同时提高模具设计的准确度，保证模具设计的合理性，最终达到提高挤压生产效益的目的。

Database System for Design of Extrusion Dies

Based on the principles of structured program design and normalized database design, a data- base system for the design of extrusion dies was developed. The system includes six design modules for six types of dies (dies for bars, dies for solid shapes, hollow section dies, dies for wall panels, spreading dies, dies with flow guid) and one system maintenance module, is not only the main sources of expert experience and de- sign criteria, but also the supporting layer for the self-learning and self-accumulating in expert system for the design of extrusion dies. As an independent software, the system can accumulate experience and data related to die design, act as design standards manual and accomplish the calculations of certain design parameter and strength conditions of extrusion dies. The system is useful for decreasing designers' workload, improving the accuracy and rationality of die design.
