An Analysis on the Forming Characteristics of commercial pure Aluminum AA 1100 in Radial-Forward Extrusion Process
In this paper, the forming process of a central hub by radial-forward extrusion has been analyzed by using the finite element software, ABAQUS. In this process, the material flows in radial direction and then deflects 90 degrees into the same direction as that of punch movement. Radial extrusion is used to produce parts that generally feature a central hub with radial protrusions. Design factors such as mandrel diameter, die corner radius, die fillet radius, mandrel corner radius, tube wall thickness and frictional conditions are applied to the present study by simulation. Commercially pure Aluminum AA 1100 is selected as a model material for analysis in the present study. The influence of these design factors on the force requirement during the forming operation is investigated and the simulation results are quantitatively summarized in terms of force-stroke relationships, and maximum force requirement for forming, respectively. The main goal of this study is to investigate the effect of those process parameters on the deformation pattern in radial-forward extrusion prccess, especially the effect of tube wall thickness.
