The paper is focused on an analysis and optimization of the rotary draw benging process to eliminate bent tube ovality by modification pressure bar geometry. bending realized WafiosCNC machine. A that for automotive application made 34MnB5 steel. Currently, after angle 120°, unacceptable occurs. Therefore, it necessary improve quality production thus prevent formation ovality. In this case, ge...

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...
