A Review on Deep Drawing Process

Abstract

Deep Drawing (DD) process is the one in which a punch forces a flat sheet metal blank into a die cavity. DD can also be described as the process which involves conversion of flat thin sheet metal blanks into parts of desired shape. Little work is available in the applications of DD processes at elevated temperatures which is going to be a very important manufacturing application in the coming decades. Deep Drawing (DD) is one of the sheet metal forming processes widely used in automobile, aerospace, electronics and allied industries to produce the hollow parts. The improvement in the deep drawing manufacturing process with latest methodologies leads to developments in the automobile and other sheet metal industries. Still today, this process of analysis and design is an art than science. Presently, the conventional deep drawing (CDD) operation is carried out at room temperature in industries. Although the deep drawing process of high strength / low formability metals has an extensive industrial application area, deep drawing at room temperature has serious difficulties because of the large amount of deformations revealed and high flow stresses of the materials. The present paper gives an overview of deep drawing process, its classification along with advantages, limitations and applications.

AHP and TOPSIS based selection of aluminium alloy for automobile panels

“…As mentioned in the earlier section, the weight of an automobile can be reduced by replacing steel with an alternate material namely Aluminium.Cantor et al [7] and Toroset al [8] observed that depending on different regions and different manufacturing strategies wide range of aluminium alloys are applied in body panels. Based on features such as strength and formability, various alloys such as Heat treatable and non-heat treatable alloys are used in panels, developed from deep drawing process [9]. Further a survey is conducted on the available literature [10][11][12][13] w.r.t.…”

Punch Motion Curve in the Extrusion–Drawing Process to Obtain Circular Cups

“…According to results obtained again using DEFORM, the punch force required for drawing decreased as the pulse frequency was increased, and when the motion curve was limited to the drawing of the circular cup, the formability of the circular cup was enhanced, and the chance of breakage was reduced. Swapna, Rao, and Radhika, in 2017, performed circular cup drawing with stainless steel, brass, and high-strength low-alloy steel [9]. These materials were selected because most studies have used aluminum or magnesium alloys.…”

A review of manufacturing processes, mechanical properties and precipitations for aluminum lithium alloys used in aeronautic applications

“…During deep drawing process, several defects may appear on the parts, mainly the fracture or tearing, wrinkling, and earing [ 47 ]. These defects can be the result of the process, material and geometric parameters [ 48 ].…”
