The study of effect on air rub press plate with hole of deep drawing parametres

Deep drawing is a method to give shape a sheet metal which has many common area for using in industries. Beverage cans, saucepans and tubes are produced using that method. The method has some problems and open sides to improve. Many investigations have been done to improve the deep drawing.In deep drawing process, blank holder is used to prevent wrinkling of sheet metal and to produce deeper cups. In this study, a new blank holder having several holes on it, has been designed and manufactured. Many holes have been drilled on the surface of the flat surfaced blank holder, doing so, friction has been decreased.Many experiments have been done using blank holder with air friction with or without ball and compared with flat surfaced blank holder. In the experiments, cylindrical cups were produced using A1-1050 aluminum alloy sheet, thickness of 1 mm. Experimental results show that, deeper cups can be obtained without fracturing using blank holder with air friction and maximum blank diameter has been denoted.Keywords: Al-1050, Blank holder, Deep Drawing, Sheet forming
