Design & Development of Three Roller Sheet Bending Machine

Abstract

Metal forming can be defined as a process in which the desired size and shapes are obtained through plastic deformation of a material without any significance loss of material. Bending is a metal forming process in which straight length is transformed into a curved length. Roller forming is a continuous bending operation in which a long strip of metal is passed through consecutive sets of rollers, until the desired cross sectional profile is obtained. The roller bending process usually produces larger parts of cylindrical or conical cross sections in large quantity. Normal practice of the roller bending still heavily depends upon the experience and skill of the operator. Trial and Error is a common practice in the industry. Rolling process always began with crucial operation of pre bending both ends of the work piece. This operation eliminates flat spot when rolling a full cylindrical shape and ensures better closure.
