WHAT IS ALUMINUM BENDING MACHINE?
For cold bending aluminum profiles (extrusions), there are two popular types of bending machines: roll bending and stretch forming. In contrast, press bending and fluid cell presses are less common.
Regarding aluminum profile bending, aluminum alloy is lightweight and highly malleable, allowing it to form complex shapes. As a result, this reduces assembly time and costs while producing parts quickly. Additionally, the most common bent aluminum parts are structural components. Compared to welded parts, bent structural parts are more aesthetically pleasing and offer greater strength.
The most commonly referred to aluminum bending machine is the three-roll aluminum profile roll bending machine. This machine is favored due to its wide range of applications.
Aluminum bending machines also named: Profile Bending Machine, Aluminium Profile Bending Machine, Aluminium Extrusion Bending Machine, Aluminum Pipe Bending Machine, and Aluminium Bender Machine.
PBA ALUMINUM BENDING MACHINE OPEN UP POSSIBILITIES NEVER BEFORE POSSIBLE
HOW STUFF WORKS
The operational principle of the 3-roll variable geometry aluminum bending machine involves all three rolls being capable of movement. During the rolling process, the top roll applies pressure to the aluminum profile between the two bottom rolls.
A common aluminum profile bending machine is a 3-roll variable geometry bending roll. By reducing the distance between the bottom rolls and pressing the top roll on the initial part of the aluminum profiles, it is possible to minimize the unbendable straight section.
The technological innovations, accuracy, speed, and excellent bending performance of the PBA aluminum bending machine make it stand out in aluminum profile bending applications.
Note: In the video, prepainted aluminum extrusions are roll-bent using the PBA profile bending machine without leaving any marks on the surface.
USES OF ALUMINUM BENDING MACHINE
The aluminum profile bending machine employs simple, flexible, and efficient bending technology. This provides a reliable solution for bending various non-standard metal profiles and processing aluminum alloy profiles.
It finds application in fields such as architectural doors and windows, curtain walls, decoration, the automotive industry, aerospace, rail transit, elevators, bathroom fixtures, shipbuilding, tunnels, bridges, and lighting.
PBA series aluminum roll bending machines offer versatility and precision, delivering exceptional craftsmanship to meet diverse market demands. For instance, with DXF and STEP import capabilities, once designed, the workpiece can be easily reproduced, ensuring seamless curves and intricate designs for various applications.
Aluminum extrusion bending accuracy includes curvature, repeatability, and cross-sectional deviation.
Top 3 Important Factors for Perfect Aluminum Bending
CURVATURE ACCURACY
With digital technology, any curvature can be achieved. However, the accuracy of bending aluminum profiles is affected by springback.
Therefore, the focus is on solving springback to achieve precise and consistent workpiece dimensions.
In mass production, the key is to quickly resolve springback with the simplest operation.
PBA’s unique CNC operating system addresses springback in two steps: input the actual radius to get the coefficient, then input the compensation coefficient and start production.
Note: Springback refers to a material’s tendency to return to its original shape after being bent. It attempts to revert to its original shape at a certain angle.
REPEATABILITY
When scaling up aluminum profile bending production, it is crucial that thousands of parts of the same design maintain consistent dimensions from month to month.
Typically, the expectation for aluminum bending is that production should provide interchangeable parts from batch to batch.
PBA’s aluminum bending machines utilize a combination of motion controllers and servo motors to ensure precise repeatability of aluminum bending workpieces, with a repeat position accuracy of ≤0.01mm.
Notes: In contrast, if driven by hydraulic cylinders, repeat positioning speed and accuracy (≤0.02mm) can be easily affected by temperature.
CROSS SECTIONAL DEVIATION
When aluminum profiles are bent, the inner radius undergoes compression, while the outer side experiences tension. As a result, the metal flows in a specific way under constant yield conditions into certain unconstrained areas, causing cross-sectional deviation.
To prevent deformation (cross-sectional deviation) caused by stress, especially with asymmetrical profiles, custom internal support tools are crucial. Therefore, a reliable expert is needed to design these tools.
The perfect aluminum profile bending workpiece should be free from deformations or surface defects. In summary, not every manufacturer can provide a flawless tooling solution. Distortions, scratches, wrinkles, and cracks are unacceptable to customers.
