Aluminum Bending Machine

The aluminum bending process, also known as profile rolling or stretch bending, involves using a bending machine to customize and process aluminum extrusion alloy profiles to achieve a specific curvature.

The aluminum profile bending machine uses a simple, flexible, and efficient bending forming technology. It is widely used in various fields such as architectural doors and windows, curtain walls, decoration, automotive industry, aerospace, rail transit, elevators, bathroom fixtures, shipbuilding, tunnels and bridges, and lighting. This technology provides a reliable solution for the bending of various non-standard metal profiles and the production and processing of various aluminum alloy profiles.

PBA Aluminum Bending Machine: Once designed, the workpiece can be reproduced at any time (DXF, STEP Import): A wide range of complex aluminum bends can be achieved, including 3-D, S-shaped, C-shaped, U-shaped, full circle, ellipse and multiple radii.

Curvature Accuracy

With digital technology, any curvature can be achieved.  But the curvature accuracy of bending aluminum profiles is affected by springback. 

Now, the focus is now on solving springback to achieve precise and consistent workpiece dimensions.

In mass aluminum bending production, the most important thing is to use the simplest operation to quickly resolve the springback in a very short time.

In the PBA’s unique operating system, solve the springback problem 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 ability to return to its original shape after being deformed when it attempts to return to its original shape at a certain angle after being bent.

Repeatability

When scaling up the production of aluminum profile bent parts, thousands of parts of the same design have consistent dimensions from one month to the next.

The default expectation for aluminum bending is 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 the precise repeatability of aluminum bending workpieces: Repeat Position Accuracy ≤0.01mm.

Notes: If driven by hydraulic cylinders, repeat positioning speed and accuracy( ≤0.02mm) are easily affected by temperature.

Cross Sectional Deviation

When aluminum profiles are bent, the inner radius undergoes compression while the outer side experiences tension. This forces the metal to ‘flow’ in a specific way under constant yield conditions into certain unconstrained areas, which is what causes cross-sectional deviation.

Crucial to prevent the deformation(cross-sectional deviation) caused by stress, especially when dealing with asymmetrical profiles. In the aluminum profile bending process, custom internal support tools are the best solution for addressing cross-sectional deviation, you need a reliable expert to design these tools.

The perfect aluminum profile bending workpiece should not have deformations or surface defects. ( Distortions, scratches, wrinkles, and cracks: No customer will accept this bad result.)
