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.

Influence Of Process Parameters

The Ugine-Se´journet patent for glass lubrication of metals extrusion made it possible to extrude steel in large quantities. A cold pad of glass powder inserted between the die and the billet head melts progressively, providing a high viscosity glass film between the die and the metal. The authors propose a theoretical model of the lubrication mechanism: progressive melting, hydrodynamic flow, and stability of the film. The influence of process parameters is discussed and results are compared with experimental measurements.

Springback is a common defect caused by elastic recovery in the plastic forming process, which can cause the formed workpiece to deviate from the target shape. The purpose of this paper is to grasp the influence law of process parameters on springback deviation so as to optimize process parameters to reduce springback. Taking the Y-profile as the research object, the influence of process parameters such as horizontal bending radius, vertical bending radius, transition zone length, radius of roller dies, and wall thickness of the profile on springback deviation is discussed by numerical simulation. Additionally, the validity of the numerical simulation is verified through experiments. The springback law obtained by numerical simulation is applied to practical production, and the large-scale production of the Y-profile is realized.
