【摘要】：传统大型压力容器封头模具在冲压成形过程中易出现磨损失效,降低了封头产品质量和模具使用寿命,严重影响生产效率。利用ABAQUS软件建立了与大型压力容器封头实际冲压成形模具一致的有限元模型,通过进行有限元模拟分析及相关冲压成形实验,对封头模具易磨损的主要因素进行对比分析,并对传统大型压力容器封头模具的材料硬度值、摩擦系数、凸模和凹模间隙进行合理改进。结果表明,选择模具材料硬度值在75~85 HRC之间、摩擦系数在0.06~0.12之间、凸模和凹模间隙在1.1~1.3 mm之间时的模具磨损量最小。
[Abstract]:Traditional large pressure vessel head die is prone to wear failure during stamping process, which reduces the head product quality and die service life. The production efficiency is seriously affected. The finite element model which is consistent with the actual stamping die of the large pressure vessel head is established by using ABAQUS software. The finite element simulation analysis and the related stamping forming experiment are carried out. The main factors of easy wear of head die are compared and analyzed, and the material hardness, friction coefficient, punch die and die clearance of traditional large pressure vessel head die are improved reasonably. When the hardness of die material is between 75 ~ 85 HRC, the friction coefficient is 0.06 ~ 0.12, and the clearance between punch and die is 1.1 ~ 1.3mm, the wear rate of die is minimum.
