Deep Drawing Operation In Sheet Metal

Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch.

Deep drawing operation in sheet metal.

The process is considered deep drawing when the depth of the drawn part exceeds its diameter. Bar tube and wire. It is thus a shape transformation process with material retention. Deep drawing is a sheet metal forming process.

Bar tube and wire drawing all work upon the. Metal sheets are largely used in manufacturing industries due to its easy operation light weight and ability to be converted into various shapes. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it. Sheet metal drawing becomes deep drawing when the workpiece is drawing longer than its diameter.

There are various advantages of sheet metal products which make it an versatile operation. The first one is sheet metal cutting second one is sheet metal bending or forming and the last one is known as deep drawing in this article we mainly focus on sheet metal cutting operations and other two we will discuss into upcoming articles. Deep drawing is mainly used for producing cup shaped components. A deep draw process may have one or more drawing operations depending on the complexity of the part.

Deep drawing is a sheet metal forming operation where sheet metal blank is drawn into hollow shapes by utilizing the combination of tensile and compressive forces. It is common that the workpiece is also processed using other forming processes such as piercing ironing necking rolling and beading in shallow drawing the depth of drawing is less than the smallest dimension of the hole. One of the primary defects that occurs in deep drawing operations is the wrinkling of sheet metal material generally in the wall or flange of the part. Wrinkling and deep drawing operations.

Mainly sheet metal process can be divided into three types. Cutting and forming thin sheets of metal usually performed as cold working sheet metal 0 4 1 64 to 6 mm 1 4in thick plate stock 6 mm thick advantage high strength good dimensional accuracy good surface finish economical mass production low cost. Sheet metal also provides good strength. Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.

In deep drawing operation when the force is applied by using the punch the sheet is simply pulled into the die without any shearing action and taking the shape and size same as that of the die.
