摘要: 針對水平Ⅴ型錐面砧拔長矩形截面坯料建立了力學模型,并進行了定性物理模擬實驗與生產性實驗.研究結果表明,水平V型錐面砧不僅可以實現變形均勻的無橫向拉應力鍛造,而且提高了軸類鍛件的橫向力學性能,實現了大型軸類鍛件的等向鍛造,同部位力學性能值的橫縱向之比均約等于1.00.Abstract: 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.
