Hollow Aluminum Rod Handle Bending | Clean U-Bends
A rotary handle bending machine forms U handles from hollow aluminum rod - the tube stays round at the bend and rows of matching parts pile up at the station.
Key Specifications
- Materials
- Hollow aluminum round rod
Key Features
- Bends hollow aluminum rod without flattening the section
- Clamp blocks index each rod for matching leg lengths
- Clean bend radius visible on the open tube ends
- Fast manual cycles fill rows of parts at the table
How Is Hollow Aluminum Rod Bent Without Collapsing the Tube?
Short answer: The rod wraps around a die pin while clamp blocks support the section through the bend. This video shows a handle bending machine forming U handles from hollow aluminum rod - the open tube ends in the close-ups show the section staying round with clean radii, and rows of matching parts pile up beside the station.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Manual insertion into clamp blocks | Rod indexed at the bend line |
| Form | Rotary wrap die, hydraulic stroke | Round section, no collapse or wrinkle |
| Repeat | Second leg at the same station | Matching leg lengths |
| Batch | Parts laid in rows on the table | Identical handles per run |
Key Applications
- Aluminum pull handles and U parts for cabinets and enclosures
- Hollow rod hardware needing clean cosmetic bends
- Handle hardware (拉手五金) batch production
- Mixed-finish runs - bare and black anodized parts
Rotary Wrap Bending vs. Press Bending Hollow Rod
| Criterion | Press bending | Rotary wrap bending |
|---|---|---|
| Hollow section at bend | Flattens, wrinkles | Stays round, as shown |
| Bend radius | Springback varies | Die-limited, consistent |
| Leg repeatability | Re-measured | Clamp blocks index each rod |
| Cosmetic parts | Often reworked | Direct from station |
FAQ
What stock is bent in this video? Hollow aluminum round rod - the open tube ends are visible in the close-ups.
Does the tube collapse at the bend? No - the clamp blocks support the section while it wraps the die pin, and the finished parts show round, clean bends.
Can the machine run other handle shapes? Yes - die pins and clamp blocks are matched to other diameters, leg lengths and bend patterns on request.
