AbstractPush bending process is one of the methods for bending tubular parts It is a suitabletechnique to make a considerable small bending radius The method is performedusing a rigid die to guide and form the tube into the required shape while beingpushed by a punch A pressure media is used within the tube to prevent wrinkling andbuckling The hyper elastic rubber materials are commonly used as pressure media This paper presents the pressure distribution within the tube before and duringbending process Theoretical result of pressure distributions obtained by a closed formsolution is compared with the finite element simulations of the process Effect ofrubber properties on the tube quality is also studied Finally optimum workingconditions of process is predicted by the finite element method and is compared withexperimental observations
