Investigation On The Formability of Magnesium Alloy of 3C Products Under Hybrid Embossing Processes

摘要

This study investigates the formability of AZ31 magnesium alloy sheet when pressing the product with concave and convex shapes by embossing process. Firstly, finite element software DEFORM is applied to simulate the effect of process parameters on forming characteristics under embossing process. Process parameters considered in the study includes die radius, constant friction factor, draft angle and indentation depth of embossing. By the changes of process parameters, the forming loads and completeness of die pattern with concave and convex shapes are discussed. Secondly, take one set of simulated parameters to fabricate an experimental die, embossing experiments are carried out by using magnesium alloy sheet, the experimental results are compared with the simulated results to prove the accuracy of simulation model.
