Abstract

The report presents the design of a 13-roll leveler for straightening sheet blanks of complex configuration. The roll leveler is equipped with a mechanism for controlling the roll gap, which during the levelling process compensates for the elastic deformation of the housing and maintains the specified levelling conditions. The levelling process was analyzed using the finite element method (FEM) with the determination of forces acting on the rollers during levelling of sheet blanks up to 50 mm thick.
