Formulation of springback and machine setting parameters for multi-pass three-roller cone frustum bending with change of flexural modulus
Source abstract
Abstract
Roller bending process can be used to plastically deform a sheet or plate to hollow shapes of constant (i.e. cylindrical, elliptical) or varying (i.e. cone frustum) cross sections. Cylindrical and conical shells are the basic components of vessels and structures used for the various engineering applications. Reported work discuss the formulation of springback and machine setting parameters for continuous multi-pass bending of cone frustum on three-roller bending machines with non-compatible (cylindrical) rollers. Effect of change of flexural modulus during the deformation on springback prediction is analyzed. Effect of plate initial radius, number of bending passes and step interval for two successive bend radii on the springback is presented. Analytical results of multi-pass cone frustum bending were verified with the cone frustum bending experiments and found to be in good agreement. Work reported is expected to improve the accuracy and productivity by facilitating the fabrication engineers.
