摘要：
The corner filling of hexagonal convex ring is an important basic problem in the variable section forming technology of tube. It is easy to crack the tube in the forming area of the corner and difficult to obtain qualified products. This paper presents a new method of forming hexagonal convex ring with ultrasonic-assisted granular medium forming (UGMF) technology. Based on the finite element method (FEM) and discrete element method (DEM) coupling model, the wall thickness of tube, the shrinkage length of tube end, forming force, and the radius of corner are investigated. The experimental results show that vibration can reduce the radius of corner forming, improve the wall thickness distribution of corner area, and reduce the forming force. All these results indicate that UGMF is a new forming technology for convex ring tubes with hexagonal.
