Deep Drawing Operation In Sheet Metal

It is a cut in a straight line across a strip sheet or bar.

Deep drawing operation in sheet metal.

Deep drawing is a sheet metal forming process. And the punch is hit at the other end of the sheet producing a shearing effect. The process involves a punch with a round comer and a die with a large radius. It is thus a shape transformation process with material retention.

There are various advantages of sheet metal products which make it an versatile operation. It leaves a lean edge on the piece of metal is sheared or cut. 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.

But the edges of the blank will be lifted upwards and produce the foldings or wrinkles on the deep drawing component. The manufacturing of deep cuplike products from thin sheet metal is known as deep drawing. 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. After these operations part finish operation such as trimming cutting cleaning or powder coating is done.

As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking. This is achieved by redrawing the part through a series of dies. Meaning of deep drawing. Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.

A part is said to be deep drawn if the depth of the part is at least half of its diameter. 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. This will cause the sheet metal to now be drawn in the opposite direction as the first draw.

Forces in deep drawing sheet metal. Two main factors will cause the punch in deep drawing to draw the metal into the die cavity rather than shearing it. Otherwise it is simply called general stamping. 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.

The punch die clearance is slightly larger than the thickness of the sheet metal to be deep drawn. This process involves four operations using tool and die to convert a sheet metal blank into formed sheet metal part. The process is considered deep drawing when the depth of the drawn part exceeds its diameter. Deep drawing operation utilizes compressive and tensile forces to convert flat sheet metal blank into a hollow body.
