Скачать или смотреть How to Bend Aluminum Flat Bar with a Stretch Forming Machine

Stretch forming is one of the most effective and precise methods to bend aluminum flat bars, especially when high repeatability, smooth curves, and distortion-free results are required.

🔧 What Is Stretch Forming?

Stretch forming involves clamping both ends of the aluminum flat bar, applying a controlled tensile force, and then bending the material over a die. This keeps the profile under tension during deformation, which:
• Prevents wrinkling or buckling
• Reduces springback
• Maintains dimensional accuracy

⸻

🧰 Steps to Bend Aluminum Flat Bar:
1. Material Setup
Mount the aluminum flat bar into the machine’s hydraulic jaws or clamps.
2. Apply Tension
Stretch the material longitudinally to a calculated force based on bar thickness and alloy (e.g. 6061-T6, 6063-T5).
3. Forming Over Die
While under tension, the bar is wrapped over a precision die to match the desired radius or contour.
4. Hold and Release
After reaching the target shape, the stretch force is released. Due to controlled tension, springback is minimal.

📐 Advantages of Stretch Forming Flat Bars:
• No wrinkling or edge collapse, even on tight radii
• High accuracy for architectural and structural uses
• Ideal for long parts or custom arcs
• Works well with thin and wide bars (e.g. 100 mm × 6 mm)

⸻

⚙️ Applications:
• Curtain wall frames
• Decorative aluminum trim
• Structural curves in transportation or building projects
• Solar panel and canopy structures
