Drawing Analysis of Aluminum Alloy Aa1200 Sheet Metal
Abstract
Here presents a new technique for deep drawing of cylindrical cups and the aim of this work is investigation of sheet metal forming using a punch with blank-holder. In this technique a cylindrical cup is produced by pushing a circular blank using a flat-headed circular punch through a cylindrical die. Effects of die and punch geometry including, coefficient of friction, blank-holder pressure, punch velocity, drawing load and thickness strain of the cup have been investigated numerically for optimal process design.
