摘要:
发展和应用精密成形技术是一个节约能源、节约材料、提高效率的有效途径。精锻技术在汽车、宇航、机械、电子等支柱产业的发展中得到了广泛的应用。本文从成形件的弹性变形、模具的弹性变形、模具的磨损以及热胀冷缩几个方面综合论述了精锻产品精度预测技术的研究现状及存在的问题,并对其未来可能的发展趋势进行了分析和探讨。
Precision forming technology has the unique advantages compared to the traditional machining technology, for example, saving energy and material as well as increasing the efficiency.It has been used widely in automotive, aerospace, mechanical and electronic industry for its efficiency and precision. In this paper, the advance of precision forging parts' accuracy prediction technology is systematically illustrated in the aspects of part elastic deformation, die elastic deformation, die wear, thermal expansion and shrinkage of part and die.Some problems of precision forging products' accuracy prediction technology have been expounded based on present research. It also analyzes and discusses the development trends.
