Abstract

Different from the conventional stamping process, rubber forming uses a rubber pad contained in a rigid box to act as a punch. The main attraction of the process is its simplicity, and it can be used for prototype development or for low-volume production. In this study, an axisymmetric rubber-pad forming operation is investigated via numerical simulations and experiments. Some key process parameters, such as rubber material, hardness of flexible punch, stamping velocity, rubber-pad thickness, and friction are studied in detail. Good correlation is achieved between the finite element predicted and experimentally measured thickness-thinning in the formed part. Stress and strain distributions in the specimen are investigated numerically during the process using ABAQUS/Standard.
