摘　　要：针对曲轴锻造平衡块塌角问题,从加热、工艺、模具等不同的角度分析了锻造过程中可能出现缺陷的原因,阐述了NTR法的锻造工艺特点和相应的解决措施,并简单介绍了德国的"CAT EAR"镦锻模具。通过实际生产验证了NTR法锻造的可行性和优越性,为全纤维曲轴的锻造提供了新的理论依据和实际经验。This article analyzes the reasons for possible sunk defects problem occurring during forging to crankshaft balance block from such aspects as heating, process, mould, etc. It also describes NTR＇s technical characteristics and its solutions to the sunken defects problem, and meanwhile, Cat Ear forging mould from Germany is also introduced in a simple manner in this article. NTR solutions have been to be self-evident of its feasibility and superiority through the accumulated experience of the practical factory productions, which also provide a new theoretical basis and also the practical manufacturing experience for upset forging of full fiber crankshafts.
