对0Cr21Ni6Mn9N钢管接头锻件进行工艺分析,设计了下模镶块,解决了管接头锻件的成形。首次试制时管接头锻件出现了比较深的折叠缺陷。使用Simufact.forming锻造工艺模拟软件对锻件的成形过程进行了模拟。结果显示,在挤压力的作用下,在模具中部向内流动的金属产生折叠。进行工艺改进——在折叠位置处增加成形凸台。改进的工艺实施后消除了向内流动现象,解决了折叠缺陷。 Process analysis of 0Cr21Ni6Mn9N steel pipe joint forgings was designed, the lower mold insert was designed to solve the forming of the pipe joint forgings. The first trial of pipe fittings forgings appeared deeper folding defects. Forging process simulation was simulated using Simufact.forming forging process simulation software. The results show that the metal flowing inwardly in the middle of the mold is folded under the effect of the pressing force. Make process improvements - Add forming bosses at the folded position. Improved process to eliminate the phenomenon of inward flow, to solve the folding defects.
