Deformation Behaviors of Tube Rotary-Draw Bending Filled with Steel Balls

摘要：

Wrinkling, wall thickness overthinning and crosssection distorting are main defects that seriously affect the forming quality of the tube in bending process. In this paper, numerical simulation based on PAM-STAMP 2G is conducted for the tube rotary-draw bending filled with steel balls as pressure transferring medium to analyze the deformation behaviors under various internal pressures. The results show that, tube bending filled with steel balls as pressure transferring medium can effectively restrain the defects of wrinkling and cross-section distorting. In addition, wrinkling and cross-section distorting of the bent tube decrease, the wall thickness thickening at the intrados of the bent tube decreases while the wall thickness thinning at the extrados increases with the internal pressure.
