摘    要:针对楔横轧多楔精密轧制长轴类零件中工艺参数的确定主要依靠经验、轧件缺陷频繁发生的难题,采用自主开发的多楔命令流有限元程序对多楔轧制过程进行有限元数值模拟,从理论上较详细分析成形角、展宽角和断面收缩率三个主要工艺参数对轧件内部等效应力、应变和轴向位移的影响,得到其相应的变化规律,并对断面收缩率对轴向位移的影响规律进行实验验证.

关 键 词:楔横轧  多楔  成形机理  工艺参数  主要工艺参数  楔横轧  多楔  轧制成形机理  影响分析  rolling  wedge  cross  deformation  mechanism  influence  process  parameter  实验验证  变化规律  轴向位移  应变  等效应力  断面收缩率  宽角  理论  数值模拟

Abstract:As to the difficulty of frequent work-piece failure and technological parameter selection by experiment in multi-wedge cross wedge rolling (MCWR) for long-axle parts, a multi-wedge command stream program in FEM was developed by authors to simulate the MCWR rolling process. The effects of forming angle, spreading angle and reduction in area on the inner equivalent stress, strain and axial displacement of work-pieces were theoretically analyzed and the corresponding regularities were obtained. The rule of the effect of reduction in area on the axial displacement of work-pieces was verified by experiment.
Keywords:cross wedge rolling  multi-wedge  deformation mechanism  process parameter
