CNC Aluminium Profile Bending Machine

Aluminum Bending Machine

PBA aluminum bending machines with repeatable high accuracy and speed. Ease to master complex aluminum bending tasks: Reliability for both low and high volumes.

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.

HOW STUFF WORKS

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 straight section.

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.

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.

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.

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.

FAQ & VOTERS

FAQ

  • What Are The Installation Location Requirements?

    Concrete floor can meet the requirements, no other special requirements.

  • Which Hydraulic Oil Should Be Used And How Much Oil Should Be Used?

    The PBA 500, PBA 500+, and PBA 600+ models are all driven by servo motors and do not require hydraulic oil. Instead, a small amount of lubricating oil is used for maintenance.

    In contrast, the PBA 600, PBA 1000, and PBA 1000# models use a hydraulic cylinder to drive the Y axis and require 46# anti-wear hydraulic oil. Specifically, the PBA 1000 and PBA 1000# models use 250 liters of oil.

  • Which Anchor Bolts Should Be Used To Fix The Machine?

    PBA series machines do not need to be fixed to the ground. Moreover, the machine will not vibrate during operation. The weight of the machine itself stabilizes the aluminum bending process.

  • Does The Machine Have A Pneumatic Diagram?

    PBA has no pneumatic components, so no pneumatic diagram is provided.

  • Is There An Installation Diagram?

    PBA is a ready-to-use machine, the whole machine is fully installed, so there is no need to provide an installation diagram.

  • Is There A Layout Diagram?

    We provide the machine’s installation dimensions. Therefore, you need to place the machine in a location with ample operating space, storage for aluminum profiles, and space for bending workpieces.

  • What Is The HS Code?

    HS Code:8462269000;

    For India(HSN), it is coded as: 84622690
