摘　　要：内高压成形是以某种传力介质,使管材成形的一种现代塑性加工技术。与传统工艺制造出的三通管相比,内高压成形的异径三通管质量高(强度高、精度高),且成本低(减少成形和装配工序)。本文进行了异径三通管内高压胀形的一系列实验研究,分析了异径三通管成形的主要影响因素,获得合理的工艺参数。结果表明,选用纯石蜡为胀形传力介质,成形结果较理想;几何尺寸也是较重要的参数;轴向压力为17MPa～22MPa、平衡压力为3.5MPa～4.5MPa时,成形效果较好。A series of experiments of high-pressure bulging research for three-way tube have been conducted and the main influence factors of the reducing three-way tube have been analyzed.Finally some important and reasonable parameters have been obtained. Results show that, by taking paraffin wax as the medium, the deformation result is perfect.Geometric dimensions are very important. When the axial pressure is 17-22MPa and count pressure is 3.5-4.SMPa, the effect of the forming is good.
