Twist Springback of Asymmetric Thin-walled Tube in Mandrel Rotary Draw Bending Process

Analysis of the Rotary-draw Bending Process for Thin-walled Rectangular Aluminum Tube

The Rotary-Draw Bending (RDB) process is a distinguished process employed for the precision cold bending of a hollow tube with small radius bends using Numerical Control (NC) machines. This research presents an analytical model based on the power law hardening model for the RDB processing of rectangular thin tubes. Based on the constraints of the tube in the dies and its thinness, the plane str...
