Analysis of Die Wear for Precision Forging of Spiral Bevel Gear
Pages: 52-54,65
Year: Issue:  1
Journal: Journal of Mechanical Transmission

Abstract: 采用刚塑性有限元法对弧齿锥齿轮精锻成形过程中模具表面磨损进行模拟分析,研究了摩擦因数、坯料温度、模具硬度、锻压速度等对模具磨损的影响.分析结果表明,随着摩擦因数的增大,磨损量增大;随着锻压速度、坯料初始温度及硬度的增大,磨损量减小,并且硬度是影响模具表面磨损量最重要的因素.模拟结果可为弧齿锥齿轮精锻成形工艺方案制定及模具寿命预测等提供理论依据.
