摘　　要：随着锻件尺寸和形状复杂度不断提高,所需设备的载荷吨位也在不断加大,使得成形载荷升级,不断挑战设备成形的能力。为了在中小型压力机上生产出更大尺寸或形状更为复杂的模锻件,迫切需要发展省力成形模锻工艺以实现小设备干大活的目标。为此,国内外学者在大型/复杂模锻件省力成形工艺及省力成形原理方面开展了大量研究。首先介绍了影响模锻成形载荷的关键因素,其次系统论述了等温局部加载、超塑性等温锻造、辊锻-模锻复合成形以及中空分流锻造等相关省力成形工艺的技术原理及研究进展,最后提出了大型/复杂模锻件省力精确塑性成形面临的关键难题与挑战。As the size and shape complexity of forgings continue to increase,the required load tonnage is also increasing,so that the forming load is upgraded,and the ability of equipment forming is constantly challenged. To produce die forgings with larger size or more complex shape on medium and small presses,it is urgent to develop less-loading forming die forging technology to achieve the goal of small equipment doing large work. For this reason,a lot of research on less-loading forming technology and less-loading forming principle of large-sized/complex die forgings was carried out by scholars at home and abroad. Firstly,the key factors affecting the forming load of die forging were introduced. Secondly,the technical principle and research progress of isothermal local loading,superplastic isothermal forging,roll forging-die forging composite forming and hollow divided flow forging and other related less-loading forming processes were systematically discussed. Finally,the key problems and challenges of less-loading and accurate plastic forming of large-sized/complex die forgings were put forward.
