Abstract
An analytical model for the ironing of deep-drawn cups is developed using the slab method. Inhomogeneous deformation of the drawn cup is taken into consideration. Elastic recovery after a cup being ironed is also modeled. Predictions on punch load and frictional force at the punch-cup interface show excellent agreements with experimental measurements. Influence of die semi-angle, ironing reduction ratio and friction on the process is investigated. With this model, new process parameters for ironing can be designed and analyzed before actual die tryout.
