本文描述了有限元法(FEM)分析大直径SUS304管冷去毛刺过程。大直径的管道如216.3毫米用于植物气体和液体的流动通道。管的去毛刺过程通常是形成分支。去毛刺成型是一种典型的分支管道的成型技术。去毛刺的过程是通过绘画的死于洞。和分支管道一般都加入了焊接。但是这个过程中有一些问题。首先,去毛刺过程取决于管的成形极限。第二,壁厚和应变分布的分支形成边缘是不平等的。这些问题是导致pre-hole形状。 It generally has difficulty to determine the optimum pre-hole shape. Many try and error is needed. In this study, we proposed that the method of estimation for optimum pre-hole shape of mother pipe by finite element method analysis. The nominal diameter of mother pipe is 200A. And the target nominal diameter of branch pipe is 100A. The diameter is 114.3 mm, and the wall thickness is 3.0 mm. And target burring wall height is 10 mm with uniformly wall height around the edge. The height 10 mm means that is not needed the machining after burring process and is easy to weld to join the branch pipe to mother pipe. Initial pre-hole shape of analysis model is simple circle. After FEM analysis, the height of burring position was measured. Then the diameters of longitudinal direction and circumferential direction was adjusted. After optimum diameter of both direction diameter was determined, the diameter of 45 °direction was analyzed by using point tracking function to estimate of initial optimum diameter. Eventually, the burring formed shape had an uniform 10 mm height. It was clarified that the method of estimation for optimum pre-hole was effective. Recent Publications 1.
