Roll forming is a continuous metal forming process, in which
roll forming machines are used to shape metal coils or sheets into parts as
the material moves through the machine. Roll forming machines consist of sequences
of roller die pairs, located on both the top and bottom of the machine. As
the metal moves through the machine, the rollers bend the material along the
linear axis, forming a variety of different configurations. Typically, roll
formed parts are created at room temperature, making this a cold forming process.
Roll forming is able to accommodate a wide selection of metals, including bronze,
brass, zinc, titanium,
copper, aluminum and steel. Of these metals, however, aluminum and steel
remain the most commonly used.
Some of the parts that manufacturers use roll forming to create include channels, angles and rings.
These parts are the foundations for many industrial products, providing
support and connection for a variety of applications. Channels provide
a support system for numerous roll-formed products, such as frames and
rails. Angles provide
support in two directions, and they are used on corners and edges. Angles also
contain holes for connecting parts. Finally, rings are
commonly rolled from other shapes and often function as container seals
and lids. In addition to standard configurations, many manufacturers
will offer custom roll forming services to fulfill customer requests.
Roll forming services can quickly and efficiently accommodate high-volume
orders. Roll forming machines are able to maintain production speeds
ranging from 100 to 180 feet per minute. Most roll forming services use
approximately 94% of the coil material during the forming operation,
resulting in fewer leftover scraps than other processes. The range of
shapes that roll forming can create is diverse, and the final products
have more consistency and tighter dimensional control. On the downside,
however, the production of extremely short parts may not be feasible
for everyone, since to cover the tooling costs, 100,000 feet per year
must be produced and sold. Roll forming is, therefore, best for high
volume productions.
A variety of industries utilize roll forming services. For the aerospace
industry, roll formed products are used for window frames, helicopter
blades and trimming.
The appliance industry uses these products for handles, drawer slides,
refrigerator shelves, ladder supports and control panels. Fence posts
and lawn and garden equipment for agriculture are other examples of the
many diverse products created from the roll forming process. Further
uses are products for vending machines, conveyor
systems,
gas station pumps, ramps, rail cars, craneways, racks and shelving, guardrails
and doorframes.

Roll Forming and Roll Formed Part Types
Angles are created
by roll forming various metals, commonly stainless
steel, and provide support in two directions. Angles often contain
holes or slots for connecting parts, which increases strength and
firmness.
Channels provide
a support system for numerous roll formed products, such as frames
and rails.
Metal channels are roll-formed products that provide a support system frames and rails.
Metal rings are circular, roll-formed parts used to join and seal.
Metal trim fits around the edge of a product or part.
Outboard mills
are roll forming machines which have housings that support both ends
of the roll tooling shafts.
Post-cut roll forming
is a process that uses continuous rolls of metal and does not cut the
piece to size until after it has been roll-formed. This process is the
most common, efficient, consistent and least troublesome roll forming
method.
Pre-cut roll forming
is a process that uses material that has been cut-to-length before entering
the roll forming machine. This method is primarily used for low-volume
applications.
Steel angles are roll-formed products made by bending a piece of steel sheet metal.
Steel channels are roll-formed products made of steel that provide a support system frames and rails.
Rings are
often roll formed from other shapes and commonly function as container
seals and lids. Stainless steal is the preferred alloy.
Common Terms Related to Roll Forming
Accumulator –
Piece of equipment that holds metal coil so the roll forming process may
continue uninterrupted while new material is attached to the coil.
Auxiliary Operations – Secondary
processes performed in conjunction with roll forming.
Camber – A deviation from a
straight line in a roll formed piece.
Coiling – Procedure in which heated flat sheet metal is transformed
into spiral coils.
Cold Work – The process of deforming
metal at room temperature in order to increase strength and hardness.
Drive System – The system responsible
for providing the roll forming machines with power and moving the metal
coils through the machines.
Ductility – The ability of metal
to bend or form without fracture.
Elastic Limit – The maximum
amount of stress a metal can accept without succumbing to permanent deformation.
End Flare – Deformation at the
end of a roll formed part.
End Joiner – Piece of equipment
that connects two coils to permit the continuance of metal coils into
the roll forming machine.
Ferrous Metal – A metal in which
iron makes up a significant component.
Levelers – Mechanism that maintains
flatness of metal being fed into the roll forming machine.
Nonferrous Metal – A metal that
does not contain iron.
Plastic Deformation – Permanent
changes in the shape of a metal that occur after pushing a metal piece
past its elastic limit. Deformation is accomplished through the application
of stress.
Pickling – The process of cleaning
steel coils in preparation for metal forming processes, such as roll
forming. The coils are subjected to hydrochloric acid that removes impurities,
such as rust, from the metal.
Reel Kinks – Imperfections in
the metal coil.
Roll Changing – The
process of changing the rolls on roll forming equipment. This is a long,
costly procedure.
Slit Edges – In reference to
the edge of sheet or strip metal that results from cutting to width by
rotary slitters.
Springback – Deformation in
a roll formed part that occurs when the roll forming process fails to
stretch a part past its elastic limit.
Sweep – Deviation from a straight
line in the horizontal plane measured after the part has been formed.
Sweep is caused because of incorrect horizontal roll alignment and/or
uneven forming pressure.
Tolerance – The acceptable
variation from product specifications, such as cross-sectional dimensions.
Trimming – Removing metal scrap
from a metal formed part in order to maintain consistency among metal
parts.
Twist – Deformation in a roll
formed part that resembles a corkscrew. Twists are caused by extreme pressure
levels created during the roll forming process.
Yield Strength – The maximum
stress which can be applied to a material without lasting deformation
of that material.
Roll Forming From Wikipedia, the free encyclopedia
Roll-forming or Rollforming is a continuous bending operation in which a long strip of metal (typically coiled steel) is passed through consecutive sets of rolls, or stands, each performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll-forming is ideal for producing parts with long lengths or in large quantities.
Variation
A variety of cross-section profiles can be produced, but each profile requires a carefully crafted set of roll-tools. Design of the rolls starts with a flower pattern, which is the sequence of profile cross-sections, one for each stand of rolls. The roll contours are then derived from the profile contours. Because of the high cost of the roll sets, simulation is often used to validate the designed rolls and optimize the forming process to minimize the number of stands and material stresses in the final product.
Roll-forming lines can be set up with multiple configurations to punch and cut off parts in a continuous operation. For cutting a part to length, the lines can be set up to use a pre-cut die where a single blank runs through the roll mill, or a post-cut die where the profile is cutoff after the roll forming process. Features may be added in a hole, notch, embossment, or shear form by punching in a roll-forming line. These part features can be done in a pre-punch application (before roll-forming starts), in a mid-line punching application (in the middle of a roll-forming line/process) or a post punching application (after roll-forming is done). Some roll-forming lines incorporate only one of the above punch or cutoff applications others incorporate some or all of the applications in one line.
