| 摘要: | 零件轮廓精度是旋压件成形质量评判标准之一. 在Simufact有限元软件中进行GH4169高温合金锥形机匣的普通旋压仿真试验, 观察到影响旋压件轮廓精度的常见缺陷: 底部隆起、底部减薄、回弹. 通过对照法对底部隆起进行尾顶块控制. 采用单因素试验法探究成形过程中主要工艺参数(旋轮进给比、芯模转速、道次间距)对底部减薄和工件回弹量的影响规律, 以最大底部减薄量和平均回弹角度为评价指标. 结果表明: 进给比对底部减薄影响最大, 道次间距对回弹影响最大. 综合对底部减薄和回弹的控制, 针对试验件工艺参数应选择较大道次间距p=20mm, 较小旋轮进给比f=0.8mm?r-1或较大旋轮进给比f=1.6mm?r-1, 较大的芯模转速n=500r?min-1. |
| Abstract: | Part contour accuracy is one of the criteria for judging the forming quality of spinning parts. Through the general spinning simulation test of GH4169 superalloy conical casing with Simufact finite element software, the common defects affecting the profile accuracy of the spinning parts were observed, including bottom bulge, bottom thinning, and springback. The bottom bulge could be controlled by the tail top block with a comparison method. The single factor test method was used to explore the influences of the main process parameters, including feed ratio, core mold speed, and pass spacing, on the bottom thinning and workpiece springback during the forming process, for which the maximum bottom thinning and average springback angle were taken as evaluation indexes. The results show that the feed ratio has the greatest influence on the bottom thinning, and the pass spacing has the greatest influence on the springback. Aiming at comprehensive control of bottom thinning and workpiece springback, the process parameters for the conical casing studied should be the following: the larger pass interval p=20mm, the feed ratio of smaller spinning roller f=0.8mm?r-1 or the feed ratio of larger rotary wheel f=1.6mm?r-1, and the larger mandrel rotational speed n=500r?min-1. |
