摘要
三通管翻边成型是一种非常复杂的变化过程,在成型过程中预制孔的形状对成型的影响非常大,所以要根据参数要求对预制孔进行计算,通过Dynaform软件进行模拟分析,找出拉拔过程中可能出现的撕裂或起皱的地方,以便对预制孔形状进行优化处理从而不仅可以保证支管没有起皱、管口撕裂等失效现象,还可以进一步提高管口平整性和支管高度。
Tee flange molding is a very complex process of change. The affect of the preformed holes is very large in the molding process, so we have to calculate according to the parameters and Simulation by Dynaform in order to find the place of torn or wrinkled during the molding process. Then we can not only guarantee that the branch pipes is not wrinkled and torn but also can improve the smoothness and height of the branch pipes by optimizing of the shape of the prefabricated holes.
