Experimental and numerical studies on the warm deep drawing of aluminum alloy

One of the most important features of deep drawing process is the production of geometrically complex ‎segments which cannot be made by other forming processes. The final segment s form depends on the ‎form of punch and matrix. By the use of various geometries, a wide range of segments with different ‎usages can be produced. There are different methods for forming the steel sheet, and one of them is deep ‎drawing process. Due to the advantages of this process it has been used in this research. Most of the ‎conducted researches about aluminum alloys are within the range of warm formability, and results ‎indicates the superiority of the gradient state to isothermal state. Thus, in this study, the gradient warm ‎deep drawing process of 5083 aluminum alloy cylindrical segments with 1mm thickness will be examined as ‎a simulation of finite elements and experimental. The results indicate that; with the increase of ‎temperature, the drawing limit will increase, as at a formation temperature of 180℃ and RAM speed of 200 ‎mm/min with graphite powder lubrication, a drawing limit of 2.28 was obtained.‎
