The Forming Process of the Sharply Curved Offsets by the Pushing Method

Abstract:

The scheme of device for the thin-walled sharply curved offset parts forming by pushing the tube-shaped workpiece through the die channel is presented. The numerical simulation of the bending process by pushing the tube-shaped workpiece is performed using ANSYS-LS/DYNA program complex. The wall thickness distribution law along the generatrix of curved workpiece is determined. The influence of curvature radius of the curved offset part on thinning deformation during bending process is defined. The experimental determination of the AISI 304 stainless steel tube-shaped workpiece thickness changes is performed. Application of the developed device for the sharply curved offset parts manufacturing according to DIN/ISO standards is demonstrated.
