摘要
锻件预成形坯料设计是保证成形工艺顺利进行、获得无缺陷锻件、降低锻造载荷的关键环节。对于大型复杂构件,其预成形坯料形状影响到制坯工艺的周期、成本、预成形组织性能。分别从基于反向模拟技术的预成形坯料设计、基于优化设计方法的预成形坯料设计、基于正向过程分析的预成形坯料设计等方面,评述了复杂构件锻造预成形坯料设计的国内外研究现状,指出了大型筋板类构件的预成形坯料形状要求以及设计方法。
Preform design of forging is the key link to ensure smooth forging running, obtain forging without defects, and reduce forging loading. The shape of preform for large-scale complex component influences time, cost, microstructure and property in preforming process. In this paper, the research status at home and abroad on preform design was summarized from the aspects such as preform design based on backward simulation technique, preform design based on optimized design method, and preform design based forward analysis of forming process. Then, the suitable shape of preform for large-scale rib-web component and the corresponding designed method were presented in detail.
