以单侧双排四通管液压胀形工艺为研究对象,运用数值模拟方法分析不同加载参数条件下单侧双排四通管液压胀形支管高度、壁厚分布和补料情况,得出单侧双排四通管液压胀形壁厚分布和补料的一般规律。结果表明:单侧双排四通管液压胀形以两支管外侧主管补料为主,支管间内侧主管补料很少。加载参数对支管高度和外侧主管补料影响较大,对最大、最小壁厚值和内侧主管补料影响很小。内侧主管壁厚分布比较均匀,厚度分界线在外侧主管且靠近支管区域。
Taking the single-side double-row four-way pipe hydraulic bulging process as the research object, the numerical simulation method was used to analyze the height, wall thickness distribution and feeding situation of single-side double-row four-way pipe hydraulic bulging branch under different loading parameters. Side double double row four pipe hydraulic bulging wall thickness distribution and feeding the general rule. The results show that the hydraulic bulging of one-way double-row four-way pipe is dominated by the main pipe outside the two pipes, and the feeding of the main pipe between the two branches is very little. The loading parameters have a great influence on the height of the branch pipe and the feeding of the main pipe outside, and have little influence on the maximum and minimum wall thickness and the feeding of the medial main line. The distribution of the medial main wall thickness is more uniform, the thickness of the boundary line in the lateral and close to the branch pipe.
