| 目的 研究不变薄凸缘的翻孔件的翻孔镦粗成形过程。方法采用有限元模拟软件ABAQUS,对不变薄凸缘的翻孔件的翻孔镦粗过程建立了平面二维对称的有限元模型,并进行了有限元计算分析;完成了模具设计,并在1000kN的伺服压力机上进行了实验。结果 当凹模圆角为1.2mm,凸凹模间隙在0.80~0.86之间时,单次镦粗可以获得与初始坯料厚度一致的凸缘。结论 凹模圆角大小及凸凹模间隙大小对不变薄凸缘翻孔凸缘质量有着重要的影响,并最终影响凸缘的镦粗过程。 |

| Objective To investigate the flanging-upsetting process of flange. Methods Finite simulation software ABAQUS was adopted to establish the 2D planar symmetrical model to simulate the process. Die was designed for the experiments which were conducted on the 1000 kN servo press. Results A flange with the thickness equal to the initial blank was obtained after one time upsetting when the female die radius was 1. 2 mm and the clearance between the punch and die was in the range of 0. 80 ~ 0. 86. Conclusion The female die radius and the clearance between the punch and die obviously affected the quality of flange, which affected the upsetting process. |
