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 metal sheets.
It is thus a shape transformation process with material retention.
The deep drawing process is a forming process which occurs under a combination of tensile and compressive conditions.
The manufacturing of deep cuplike products from thin sheet metal is known as deep drawing.
The shape and the surface profile of the tool are imprinted in the workpiece.
The processed sheet metal has an almost constant strength because it is not clamped laterally.
Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it.
The deep drawings having two main categories.
In deep drawing an even sheet metal is formed into a hollow cylinder.
The process is considered deep drawing when the depth of the drawn part exceeds its diameter.
The tensile forces applied to the sheet cause it to plastically deform into a cup shaped part.
When first stage drawing a blank shape metal is made up of cup and that formed cup is drawn again and again and then finally reaches the require shape of cup or other similar product.
Apart from its use in many other sectors it is applied in the automotive industry for the manufacturing of car body parts.
Metal sheets are largely used in manufacturing industries due to its easy operation light weight and ability to be converted into various shapes.
Sheet metal also provides good strength.
Deep drawing is a metal forming process in which sheet metal is stretched into the desired part shape.
Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.
A tool pushes downward on the sheet metal forcing it into a die cavity in the shape of the desired part.
Successful deep drawing depends on many factors.
However regardless of the many factors involved the most important element to a successful deep drawing operation is initiating metal flow.
The punch die clearance is slightly larger than the thickness of the sheet metal to be deep drawn.
This is achieved by redrawing the part through a series of dies.
Ignoring even one of them during die design and build can prove disastrous.
The first stage of drawing cannot drawn normally in high degree of deformation.
There are various advantages of sheet metal products which make it an versatile operation.
Deep drawing is a sheet metal forming process.
The process involves a punch with a round comer and a die with a large radius.
Metal deep drawing process.
As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking.
