摘　　要：-本文运用三维作图软件进行某曲轴模具设计,运用forge锻造成形模拟软件对曲轴的成形过程进行数值模拟,分析了连皮结构及压弯模结构对曲轴精密模锻成形过程中的金属流动情况、锻件成形过程中充填情况和锻造压力。通过模拟分析,优化了预锻模的连皮结构、桥部高度,达到了优化工艺参数、优化曲轴模具结构、解决充型不满问题,并能够在14000T热模锻压力机进行模锻成形锻造的目的。This paper employs three-dimensional drawing software to design a crankshaft die and uses the Forge forging simulation software to numerically simulate the forming process of the crankshaft.The study analyzes the effects of the flash structure and bending die structure on the metal flow during the precision forging process of the crankshaft,the filling conditions during the forging process,and the forging pressure.Through simulation analysis,the flash structure and bridge height of the pre-forging die were optimized to achieve optimized process parameters,optimized crankshaft die structure,and resolution of underfilling issues.The optimized design allows for successful forging on a 14,000T hot die forging press.
