Deep drawing is a metal forming process in which sheet metal is
stretched into the desired part shape. A tool pushes downward on
the sheet metal, forcing it into a die cavity in the shape of the
desired part. The tensile forces applied to the sheet cause it to
plastically deform into a cup-shaped part. Deep drawn parts are
characterized by a depth equal to more than half of the diameter of
the part. These parts can have a variety of cross sections with
straight, tapered, or even curved walls, but cylindrical or
rectangular parts are most common. Deep drawing is most effective
with ductile metals, such as aluminum, brass, copper, and mild
steel. Examples of parts formed with deep drawing include
automotive bodies and fuel tanks, cans, cups, kitchen sinks, and
pots and pans.
The deep drawing process requires a blank, blank holder, punch, and
die. The blank is a piece of sheet metal, typically a disc or
rectangle, which is pre-cut from stock material and will be formed
into the part. The blank is clamped down by the blank holder over
the die, which has a cavity in the external shape of the part. A
tool called a punch moves downward into the blank and draws, or
stretches, the material into the die cavity. The movement of the
punch is usually hydraulically powered to apply enough force to the
blank. Both the die and punch experience wear from the forces
applied to the sheet metal and are therefore made from tool steel
or carbon steel. The process of drawing the part sometimes occurs
in a series of operations, called draw reductions. In each step, a
punch forces the part into a different die, stretching the part to
a greater depth each time. After a part is completely drawn, the
punch and blank holder can be raised and the part removed from the
die. The portion of the sheet metal that was clamped under the
blank holder may form a flange around the part that can be trimmed
off.
Sheet metal fabrication is a classification of manufacturing processes that shape a piece of sheet metal into the desired part through material removal and/or material deformation. Sheet metal, which acts as the workpiece in these processes, is one of the most common forms of raw material stock. The material thickness that classifies a workpiece as sheet metal is not clearly defined. However, sheet metal is generally considered to be a piece of stock between 0.006 and 0.25 inches thick. A piece of metal much thinner is considered to be "foil" and any thicker is referred to as a "plate". The thickness of a piece of sheet metal is often referred to as its gauge, a number typically ranging from 3 to 38. A higher gauge indicates a thinner piece of sheet metal, with exact dimensions that depend on the material.
Sheet metal can be cut, bent, and stretched into a nearly any
shape. Material removal processes can create holes and cutouts in
any 2D geometric shape. Deformation processes can bend the sheet
numerous times to different angles or stretch the sheet to create
complex contours. The size of sheet metal parts can range from a
small washer or bracket, to midsize enclosures for home appliances,
to large airplane wings. These parts are found in a variety of
industries, such as aircraft, automotive, construction, consumer
products, HVAC, and furniture.
Sheet metal fabrication processes can mostly be placed into two
categories - forming and cutting. Forming processes are those in
which the applied force causes the material to plastically deform,
but not to fail. Such processes are able to bend or stretch the
sheet into the desired shape. Cutting processes are those in which
the applied force causes the material to fail and separate,
allowing the material to be cut or removed. Most cutting processes
are performed by applying a great enough shearing force to separate
the material, and are therefore sometimes referred to as shearing
processes. Other cutting processes remove material by using heat or
abrasion, instead of shearing forces.
