摘要：

精密锻造是一种近净成形或净成形技术，来自工业界的现实需求推动了该项技术的发展。针对精锻工艺、锻造模具、复杂件锻造成形以及数值模拟在精锻中的应用分别作了介绍。在工艺方面，出现了具有代表性的温锻-冷锻联合成形、分流锻造成形、流动控制成形、冲锻复合成形与闭塞锻造等新型精锻工艺；在模具结构设计方面，形成了新的方法与理念；在复杂零件的开发方面，围绕具体零件开展的工艺创新与实践依然十分活跃，虽然受到一定的应用限制，但仍具有重要的实际意义；在数值模拟技术应用方面，不断成熟的数值模拟技术使用广泛且逐渐成为必备的研发分析工具。结合以上精锻技术的发展现状，指出了精锻技术在未来的发展趋势。

Precision forging is a kind of near net forming or net forming technology, and the demands from industry push forward the development of the technology. Therefore, the precision forging process, forging die, forging of complex part and the application of numerical simulation in the precision forging were introduced respectivety. For the forging process, some new precision forging processes such as combined warm and cold forging, divided flow forging, flow control forming, forging-stamping compound forming and enclosed die forging were generated, and for the die structure design, some novel methods and ideas were put forward. And then, for the complex part development, the process innovation and practice based on detailed parts were very active, which had important significance although there was some limitation in application. At last, for the numerical simulation technology, the mature numerical simulation technology was widely used and gradually became the necessary analysis tool for research and development. Thus, combining the above status of precision forging technology, the development trend in the future of the precision forging technology was proposed.
