Deep drawing is a sheet metal forming process.
Deep drawing operation in sheet metal.
Forces in deep drawing sheet metal.
It leaves a lean edge on the piece of metal is sheared or cut.
This process involves four operations using tool and die to convert a sheet metal blank into formed sheet metal part.
But the edges of the blank will be lifted upwards and produce the foldings or wrinkles on the deep drawing component.
After these operations part finish operation such as trimming cutting cleaning or powder coating is done.
Sheet metal also provides good strength.
Otherwise it is simply called general stamping.
The punch die clearance is slightly larger than the thickness of the sheet metal to be deep drawn.
Deep drawing operation utilizes compressive and tensile forces to convert flat sheet metal blank into a hollow body.
Metal sheet close up with no wrinkles.
The process involves a punch with a round comer and a die with a large radius.
As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking.
And the punch is hit at the other end of the sheet producing a shearing effect.
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.
Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it.
Metal sheets are largely used in manufacturing industries due to its easy operation light weight and ability to be converted into various shapes.
There are various advantages of sheet metal products which make it an versatile operation.
Force used to accomplish a sheet metal deep drawing operation must be adequate enough to provide for the sheet s deformation enact proper metal flow and overcome friction during the process.
This is achieved by redrawing the part through a series of dies.
It is a cut in a straight line across a strip sheet or bar.
Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.
Meaning of deep drawing.
The flange region experiences a radial drawing stress and a tangential compressive stress due to the material retention pro.
The process is considered deep drawing when the depth of the drawn part exceeds its diameter.
The manufacturing of deep cuplike products from thin sheet metal is known as deep drawing.
It is thus a shape transformation process with material retention.
In this operation a sheet metal workpiece is placed or kept between two dies from one end.
In the deep drawing process a punch pushes a sheet metal blank into a die cavity resulting in a contoured part.
