摘　　要：道钉因为尺寸太小采用机械加工难度较大,且浪费材料、效率低。精锻加工可以避免上述缺点,产品机械性能好,表面质量高。通过分析精锻过程中的参数选择,利用Deform-3D金属体积成形软件数值模拟了35钢道钉零件的精锻成形过程。仿真过程中分别在应力、应变分布、载荷计算、材料流动速度、模具填充和毛坯优化等方面作了深入研究,为模具及成形设备的设计等工艺规划提供了可靠的依据。Because of small size the flat head nail is difficult to cut. Precision forging was used to form the part due to its good mechanical properties and excellent surface quality. Based on the selection of the process parameters in forming,the precision forging of flat head nail was simulated by Deform-3D software. Meanwhile stress and strain distribution,load calculation,material flow rate, mold filling during the forming have been detailed respectively,which provided reliable basis to forging process planning.
