摘要
热精密锻造技术不仅能赋予零件近净复杂形状和尺寸,而且能使零件宏观性能在坯料性能基础上得到提高,是少无废料产生、绿色、节约型的高效高性能制造技术。综述了热精密锻造技术的应用现状,介绍了热模锻造、等温锻造、基于数值模拟的预制坯优化设计和精密锻造全过程工艺优化设计的国内外研究现状,最后对热精密锻造技术发展方向进行了展望。
Hot precision forging technology is defined as a near net-shape forging operation which generates high-quali-ty parts concerning surface quality and dimensional accuracy. The mechanical properties of forgings are improved by hot precision forging. Precision forging is a highly efficient green manufacturing technology which eliminates or reduces genera-tion of waste, and saves raw material and cost. The paper introduced the current application status of hot precision forging technology, reviewed the current worldwide research status of hot-die forging, isothermal forging, design optimization of preformed forgings and process optimization of precision forging, and finally prospected the development tendencies of hot precision forging technology.
