Profile Bending Machine

The profile bending process video of BIT steel & aluminum profile bending machine

BIT Profile Bending Machines are equipped with a solid steel structure, servo motor or hydraulic system, and user-friendly strong bending rollers, offering fast and reliable operation and designed for minimizing energy waste.

Notes: The first half is steel profile bending, and the second half is aluminum profile bending video.

Six steps of profile bending

• Steps 1#: Loading bending metal profiles – the metal profile is inserted in between the top roller and the right lower roller. The metal profile can be supported if necessary and is not subject to deformation stress.
• Steps 2#: The right lower roller up to the top roller movement achieves the pinching position – the metal 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.
• Steps 3#: Pre-bending between the top roller and the left roller – the right roller slowly rises, starts rolling, and performs pre-bending between the top roller and the left roller.
• Steps 4#: 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.
• Steps 5#: Pre-bending between the top roller and the right roller – The left roller is down and the right roller is raised. The material is sent to the left and the three rolls begin rolling, pre-bending between the top roller and the right roller.
• Steps 6#: Unloading of the metal profile – the pressure on the profile is eliminated and is increased the space between the rollers so that the profile can be extracted from the machine.

It is clear that, in order to load the profile on the machine, a sufficient distance between the rollers 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 rollers must be capable to move with respect to the others.

Top 5 Things to Consider Before Buying A Profile Bending Machine

Choosing a CNC Profile Bending Machines may seem difficult but it really breaks down into a few simple steps. First, determine 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.

1#: Yield strength

Regarding the yield strength of the angle iron roller, BIT machines are uniformly calculated based on the yield value of Q235 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. The yield value of Q235: refers to the yield value of this material, around 235MPa.

2#: 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 distortion-mitigating tools at their disposal. Beyond tool choice and fit-up, 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.

3#: Different bending capacities

The types of metal a profile bending machine 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 profile bending machines, 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 profile bending machine is best for you. When determining which angle roll machine is best suited for the task one has at hand, it is important to research what each profile 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.

4#: Unbend end flat

PBH Series profile bending machine has the independent motion of the two lower rollers allowing the operator to minimize the sacrificial unbent flat sections on the workpiece. Beyond this, operators can fine-tune the roll position to minimize the unbent flat even further.

Again, typically a roll shop that bends a small workpiece on a large profile bending machine (section bending machine) must factor in a long flat section, which increases material costs. Due to the advantages of its structure and working principle, the Double-Pinch Profile Bending Machine solves this problem well.

Compare the information about how much force an angle iron roller can produce and what kind of metals (sheet, roll, etc.) it is designed to handle, and compare this to your site’s mill certificates or other relevant information to see which profile bending machine best fits your needs.
