摘　　要：针对水平Ⅴ型锥面砧拔长矩形截面坯料建立了力学模型,并进行了定性物理模拟实验与生产性实验.研究结果表明,水平V型锥面砧不仅可以实现变形均匀的无横向拉应力锻造,而且提高了轴类锻件的横向力学性能,实现了大型轴类锻件的等向锻造,同部位力学性能值的横纵向之比均约等于1.00.A mechanical model was established for the forging drawing process of rectangular block with a horizontal V-shaped anvil, and the quantitative physical simulation and productive experiment of the process were carried out. It is showed that the forging method with a horizontal V-shape anvil can realize no transverse tensile stress forging, improve transverse mechanical properties and achieve uniform forging for heavy axial forgings. The ratio of transverse mechanical properties to longitudinal mechanical properties is about 1.00 at the same position of heavy axial forgings.
