Paper Title:
Finite Element Analysis of Pipeline Steel Air-Bending
  Abstract

Air bending of wide-punch large radius of curvature, as a special bending mode, has been widely applied in the production of large diameter pipeline JCO forming. The JCO forming process is accomplished by several air bending processes. The quality and shape of pipe are greatly influenced by the air bending. During the present work, the bending is investigated into using the finite element (FE) method and orthogonal design of experiment. Experiments are carried out and the experimental result is very close to the result simulated by finite element analysis. Springback, forming force and residual stress are discussed. The aim of this research is to investigate the influencing degree of parameters, such as sheet material, sheet thickness, bending angle, lubrication and punch radius; in particular the effect of springback, forming force, residual stress on air bending parameters are also discussed.
