复杂零部件数字化无模制造技术研究

Research on Digital Patternless Manufacturing Technology of Complex Parts

将铸造技术与数字化制造技术相结合,介绍了发动机缸盖数字化制造方法。与基于二维图纸和铸造经验的传统铸造不同,数字化制造全流程基于三维CAD数字模型。同时,将计算机模拟分析技术与铸型加工技术相结合,实现了全流程数字化设计、数字化模拟分析以及数字化加工成型。结果表明,通过其集成应用,成功开发了六缸发动机缸盖,为复杂零部件快速开发提供了一种新的制造方法。

The digital manufacturing method of engine cylinder head was introduced by combining casting technology with digital manufacturing technology.Different from traditional casting based on 2 D drawings and casting experience,the whole process of digital manufacturing was based on 3 D CAD digital model.At the same time,the computer simulation analysis technology was combined with the casting process technology to realize the whole process digital design,digital simulation analysis and digital processing and forming.The results show that through its integrated application,the six-cylinder engine head has been successfully developed,which provides a new manufacturing method for the rapid development of complex parts.
