Processing Steps

A theory and a mathematical model are developed for calculating the parameters of the strain-stressed state at the stages of pre-bending, calibration, straightening and bending of the straightened section, taking into account the strengthening of the billet on a roll machine. By CAD/CAE modeling the strains, stresses and forces acting on the billet from the rolls are investigated. Criteria for the formation of cracks, low accuracy and excessive springing of the billet after these processing steps are determined, recommendations are given for their elimination. Keywords billet, sheet stamping, bending, roll machine, pre-bending, calibration, straightening, bending of the straightened section, CAD/CAE modeling. [email protected]
