Theoretical Analyses of Tube Granule Medium Internal High Pressure Forming Processes
摘要
Abstract
The discrete granules brough a non-uniform internal pressures and a significant friction between tube and medium to granule medium internal high pressure forming processes.Therefore,a non-uniform pressure transfer model was built for this process to investigate into theoretical analyses of tube bulging.The effects of the non-uniform pressures and the significant friction on tube forming property were studied by the theoretical analyses which were verified by processing tests.The analyses show that the non-uniform pressures and the significant friction may reduce the thickness reductions and forming pressures of tube bulging.The comparison of theoretical analyses and processing tests indicates that the calculated curves of thickness distributions and forming pressures agree well with test results.The non-uniform pressure transfer model for granule medium internal high pressure forming process may be used for the predictions and analyses of tube forming processes.关键词
