Deep Drawing Operation In Sheet Metal

Deep drawing operation utilizes compressive and tensile forces to convert flat sheet metal blank into a hollow body.

Deep drawing operation in sheet metal.

A part is said to be deep drawn if the depth of the part is at least half of its diameter. Otherwise it is simply called general stamping. This is achieved by redrawing the part through a series of dies. As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking.

Meaning of deep drawing. 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. In this operation a sheet metal workpiece is placed or kept between two dies from one end. This will cause the sheet metal to now be drawn in the opposite direction as the first draw.

In the deep drawing process a punch pushes a sheet metal blank into a die cavity resulting in a contoured part. The flange region experiences a radial drawing stress and a tangential compressive stress due to the material retention pro. 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. 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.

It is thus a shape transformation process with material retention. The punch die clearance is slightly larger than the thickness of the sheet metal to be deep drawn. Forces in deep drawing sheet metal. Sheet metal also provides good strength.

But the edges of the blank will be lifted upwards and produce the foldings or wrinkles on the deep drawing component. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it. There are various advantages of sheet metal products which make it an versatile operation. The process is considered deep drawing when the depth of the drawn part exceeds its diameter.

Metal sheet close up with no wrinkles. Deep drawing is a sheet metal forming process that involves complex material flow and force distributions. It leaves a lean edge on the piece of metal is sheared or cut. Deep drawing is a sheet metal forming process.

Metal sheets are largely used in manufacturing industries due to its easy operation light weight and ability to be converted into various shapes. The manufacturing of deep cuplike products from thin sheet metal is known as deep drawing. The process involves a punch with a round comer and a die with a large radius. It is a cut in a straight line across a strip sheet or bar.
