【摘要】 阐明了小锻比锻造的概念 ,首次提出平面变形化的原理及纵向锥面砧可实现小锻比锻造。应用纵向锥面砧还可实现无横向拉应力锻造 ,提高轴类锻件的横向力学性能。小锻比锻造新工艺具有广阔的应用前景更多还原

【Abstract】 The definition of forging with small forging ratio is given The plane deformation theory and axial cone tools are proposed firstly to perform forging with small forging ratio Axial cone plane tools can also be used to no transverse tensile stress forging and to improve transverse mechanical properties of axle shaped forgings This new forging technology of small forging ratio is promising in the future更多还原
