Three-roller plate bending machines are used in metal forming industries for bending of sheets/plates in to shells of constant or varying cross section. Maximum blank thickness, maximum blank width and minimum shell diameter combinations that can be pre-bent for given plate material specifies capacity of three-roller bending machine. Roller stands or frames supporting rollers are key structural elements in roller bending machines. Designing of the frame structure is crucial due to complex force pattern in action during static and continuous roller bending and complexity of its geometry. In reported work, behavior of different frame structure of a three-roller bending machine (i.e. maximum Von Mises stress and maximum deflection) for maximum load under static bending of varying cross-section shell is analyzed using Finite Element Analysis (FEA) in Ansys. Different possible modification in the frame structure has been considered using shape optimization module of Ansys. Alternate frame structure designs are analyzed based on FEA results of maximum Von Mises stress and maximum deflection. Reported work may be important to machine tool design engineer to arrive at a satisfactory design of machine structures.
