THE ADVANTAGES OF DOUBLEPINCH MACHINES
3roll doublepinch angle rolls are economical profile bending machines that are relatively easy to operate. The side rolls are positioned to the right and left of the top roll and are on the same axis. The axis of each roll helps make the bend. The “back” side roll (at the far side of the feeding point) also functions as a back gauge to square the plate for proper alignment. This eliminates the need for someone to assist the operator. Threeroll, doublepinch section bending machines do not require the operator to remove, flip, and then try to square the plate a second time after prebending, as is the case with threeroll, initialpinch machines.
What is Angle Roll?
Angle Roller (aka, Angle Roll, Angle Iron Roller, Angle Roll Machine, Section Bending Machine, Aluminum Bending Machine) are roll bending machines used to roll out shapes of materials to a specific radius or diameter.
Angle Rolls use a combination of powerdriven hardened steel rolls to form elongated metal shapes into rounds, semiround, or variable radius components. Structural steel bending and rolling services such as largescale components, including for wide flange beam bending, are among the most demanding metal modification tasks of angle rolls.
The rollers of angle rolls are the round parts that spin to bend and shape the metal within the machine. The rolls are powerdriven through a mechanical gear assembly or a hydraulic drive system. The distance between the rolls is adjustable to allow for various shapes and to force the material into the desired angle to be formed. Each angle roller has at least one pinching roll, that’s used to feed the metal into the machine.
BIT provides uniquely precise and automated Angle Iron Roller. Our Angle Roll always meets the highest standards and certifications.
What can Angle Roller use to do?
The angle roll can bend tubes, pipes, round & solid square & flat bars, angle irons, tee sections, H & I beams, and U channels to over 180 degrees and into circles or arcs, and is often chosen to create circular pieces.
Angle roll machines (angle iron roller) can form a variety of materials such as steel, titanium, aluminum, stainless steel, and most other malleable metals. These metals can be tubes, pipes, flats, angles, solids, extrusions, or just about any other profile you can imagine.
Working principle of Angle Roll
The basics of an angle roll machine operation are fairly simple. The process consists of taking the flat edge of the part, feeding it into the angle iron roller, and using the pinching action of two of the rollers the third roller is brought up to begin the bending process. These 3 rollers are then driven simultaneously forward and backward bending the metal to the shape desired in a series of “passes”. Depending on the yield strength of the material and the desired final shape the number of “passes” will vary. The benefit of using this method to form parts is that there is a smooth radius created and a smooth transition of radius’s from parts with varying radii.
The working phases of an angle roller(section bending machine) can be identified as:
 Loading of the part to be bent: in this phase, the profile is inserted in between the rolls. The part can be supported if necessary and is not subject to deformation stress.
 Roll movement in order to achieve the pinching position: during this phase the profile is blocked in between the rolls and can be moved forward and backward rotating the rolls. The pressure exercised is lower than the one necessary to deform the profile.
 Working phase: in this phase the pressure increases and the deformation of the profile takes place, by translation of the profile and movement of the rolls.
 Unloading of the profile: the pressure on the profile is eliminated and is increased the space between the rolls so that the profile can be extracted from the machine.
The working principle has a direct influence on all phases, but mainly on the second and third. It is clear that, in order to load the profile on the machine, a sufficient distance in between the rolls must be present. It is also clear that, in order to block the profile in between the rolls and to apply pressure, it is necessary that this distance is reduced. Une or more rolls must be capable to move in respect to the others.
Different Roll mold Styles
BIT angle rolls can be equipped with various tooling roll mold sets. Standard with every angle iron bender machine is a universal set of rolls mold that allows for a variety of shapes and profiles to be formed.
Round pipe bending needs to customize the mold according to the diameter of the pipe.
Optionally BIT offers custom roll sets that include rolls made for specific applications such as extrusions or materials that may easily be scratched or scored in the bending process.
3 different bending process types of angle roller
Angle rolls are divided into three forms according to the different roll bending processes: pyramid, single pinch, and doublepinch profile bending machines.
The number of rolls an angle roll has is an important difference, the rolls are the round, spinning parts of the angle roll that allow it to do its job.
Every angle iron roller comes with at least one pinching roll, which is the roll that holds the metal in place and allows it to be fed through the angle bender machine.
Angle roll come in two varieties: singlepinch and doublepinch, referring to how many pinching rolls it has.
Pyramidtype angle roller: It is a symmetrical bending roll bending machine.
Singlepinch and doublepinch angle roll: both of its forms are machines for asymmetrical roll bending machines. The doublepinch angle roll can perform asymmetrical and symmetrical bending processes, and the special structure makes it have a better prebending ability.
Single pinch angle roll
In the single pinch angle rollers, only one of the bottom rolls can move. With this, kind of angle iron roller it is possible to work only in an asymmetrical way. We can’t even find its pictures on the Internet.
Double pinch angle roll machine
In the double pinch angle roll machine, the top roll has a fixed position, while the bottom two can move and can be moved independently one from the other. This kind of machine is the most flexible, and consequently is the one that allows for obtaining better performances The possibility to move independently the bottom rolls allow to manage in the best way the pinching and bending operations, permitting them to work symmetrically and asymmetrically.
Pyramidal of angle iron roller
In the pyramidal section bending machines the bottom rolls have fixed positions, while the top one can be moved down. With this kind of angle iron roller, it is possible to work only in a symmetrical way.
Difference between three types of angle roller
Production costs: The double pinch angle roller style is the most expensive one to be constructed because there are more movable parts and consequently more components. The pyramidal angle iron roller and single pinch profile bending machine have more or less the same production cost.
Flexibility: Doublepinch angle rollers are the most flexible. During operations, it is possible to maintain A stable position of the profile at the loading side of the Angle Roller and use only the roll at the opposite side to bend the steel or aluminum profile. It is possible to operate in this way also in the single pinch style section bending machines, but not on the pyramidal section benders.
3roll angle roller & 4roll angle iron roller
Pressing rolls are the part of the angle roll bender that does the actual bending. Here there are even more varieties than with pinching roll.
Examples of different types of angle rollers based on the number of pressing rolls include threeroll doublepinch, fourroll doublepinch, threeroll initial pinch, and more.
5 tips for choosing the best angle iron roller
Choosing an Angle Roll Machine may seem difficult but it really breaks down into a few simple steps. First, determine the metal material you will be rolling and the maximum size and type of material you will be rolling. Next determine the types of profiles (angles, flats, tubes, etc.) that you will be forming. Lastly determine if you will be rolling material into one simple radius or if you will have or need the ability to have, the capability of forming variable radii.
Pressing rolls for angle roller
Pressing rolls are responsible for the bending process and come in far more varieties than angle iron rollers. Common examples include fourroll doublepinch and threeroll initial pinch.
Yield strength
The yield value of Q235: refers to the yield value of this material, around 235MPa.
Regarding the yield strength of the angle iron roller, BIT machines are uniformly calculated based on the yield value of Q245 and have a yield strength of between 36,000 and 38,000 pounds per square inch (PSI). If you have special requirements, please indicate the yield strength of the metal material in the inquiry.
Correctly sized
Whether operators are bending angle iron, tool choice is critical. The tools need to fit the profile yet not be so tight as to negatively affect workpiece shrinkage and growth. A tool that’s too tight can cause localized distortion and, at worst, actually gouge the material surface.
When operators need to bend an open profile like an angle, they have fewer distortionmitigating tools at their disposal. Beyond tool choice and fitup, angle iron roller must choose a correctly sized machine, one with sufficient forming tonnage and adequate grip lengths—enough to provide the needed leverage to reduce distortion, but not so long that they will require an excessively long sacrificial straight section, the long sacrificial flat section becomes expensive scrap, reducing the roll shop’s competitiveness.
How do minimize the unbent flat of the bending process?
BIT’s angle iron roller has the independent motion of the two side rolls allowing the operator to minimize the sacrificial unbent flat sections on the workpiece. Again, typically a roll shop that bends a small workpiece on a large section bending machine (angle roller) must factor in a long flat section, which increases material costs.
But because the BIT angle rollers (profile bending machines) move the way they do, an operator can move a joystick or push a few buttons on the control to reconfigure them into a smallermachine orientation. Beyond this, operators can finetune the roll position to minimize the unbent flat even further.
Different bending capacities of angle rollers
The types of metal an angle iron roller can process largely depend on its bending capacity, we use the section modulus to evaluate the capabilities of the angle iron roller. Capacity is one of the most notable differences between these angle iron rollers, each angle roll has a section modulus rating.
Make a list of the materials and the size of the metal profile you work with on a regular basis and consult an expert to figure out what type of angle iron roller is best for you. When determining which angle rolling machine is best suited for the task one has at hand, it is important to research what each section bending machine is designed to do, and to understand the materials that one will be working with.
We provided detailed information about the section bending machines, such as capacity and yield.
