When the metal specimen is flat piece of sheet metal used in forming and finish the product.
Drawing sheet metal process.
Sheet metal is formed cold.
This is accomplished by forcing the work through a mold die of smaller cross sectional area than the work.
The process is considered deep drawing when the depth of the drawn part exceeds its diameter.
The blank shape of metal is placed on the die and contact with the punch.
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 and wire bar and tube drawing.
Deep drawing is a manufacturing process that is used extensively in the forming of sheet metal into cup or box like structures.
Drawing is classified in two types.
The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis.
Pots and pans for cooking containers sinks automobile parts such as panels and gas tanks are among a few of the items manufactured by sheet metal deep drawing this process is sometimes called drawing and is not to be confused with the bulk.
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.
Metal deep drawing process diadram.
The following steps are involved in the process of sheet metal forming.
The die at the top is called a punch.
Sheet metal forming process is done on a press and the parts are formed in between two die.
This step includes bending sheet metal for creating the metal components.
Deep drawing is a metal forming process in which sheet metal is stretched into the desired part shape.
The tensile forces applied to the sheet cause it to plastically deform into a cup shaped part.
It is thus a shape transformation process with material retention.
As mentioned the punch and die setup is somewhat similar to a sheet metal cutting operation such as punching or blanking.
A tool pushes downward on the sheet metal forcing it into a die cavity in the shape of the desired part.
Deep drawing is a sheet metal forming process that involves complex material flow and force distributions.
Apart from its use in many other sectors it is applied in the automotive industry for the manufacturing of car body parts.
The deep drawing process is a forming process which occurs under a combination of tensile and compressive conditions.
