Industry Information

IQS Newsroom Articles on Roll Forming
Roll forming is a continuous metal forming process in which roll forming calenders and die punches are used to shape metal coils or sheets into linear panels, rings, angles and channels. Roll formed parts have a variety of cost-effective advantages over alternative forming processes such as press brake forming and extruding; the roll forming process creates very little scrap material while improving the structural integrity of the metal parts by creating an even, linear grainflow. Angle iron, steel angles, aluminum angles and many other types of structural linear metal parts are made by roll forming. Other parts used in construction and equipment fabrication include roll formed parts such as metal rings, steel channels, aluminum channels and other metal channels, while metal trim and metal wall panels are used for support, siding and sealing in building and facility walls and windows.

Angles, channels, metal panels and metal rings provide support and connection for a variety of structures and machines. Channels provide support systems such as frames and rails. Angles, such as angle iron, provide structural support at a 90 degree angle on building and wall corners and edges. Angles and channels may also be punched with holes or shapes to allow for hardware fastening, while steel channels and aluminum channels can be roll formed into three dimensional support structures or wall paneling for a variety of construction industries, along with steel and aluminum siding panels. Metal rings, often called "seam tubes", function as container seals and lids, among other connecting applications. The aerospace industry uses roll formed products in constructing window frames, helicopter blades and building trim. The appliance industry uses roll formed angles, channels and panels as stove handles, drawer slides, refrigerator shelves, ladder supports and control panels. Fence posts and agricultural irrigators are also constructed with roll formed parts, as are various parts in vending machines, conveyor systems, gas station pumps, ramps, rail cars, craneways, racks and shelving, guardrails and doorframes.

Roll forming machines consist of sequences of calenders, or roller die pairs positioned both above and below the metal sheet or coil which is being formed. As the metal moves through the machine, the rollers bend the material along the linear axis, pressing the metal into a more uniform grainflow while shaping the metal to specific widths and linear three dimensional shapes. Roller dies may also include punches which punch holes or shapes into the part along precise intervals as it is being formed. 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, aluminum and steel remain the most commonly used.

Roll forming services can quickly and efficiently accommodate high-volume orders, making high-volume roll form production quite cost-efficient. 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. Because initial calender die tooling can be costly, short production runs are not always as cost effective as processes with lower initial costs such as press brake forming. Roll forming is best for high volume productions, although roll forming gives parts added properties of strength and resilience which may be worth extra initial tooling costs, even for short runs.

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.



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.
