Aluminum Pull Handle Bending Machine | Clean U-Bends
An aluminum handle bending machine forms crank pull handles from small round tube with drilled ends - clean bends, matching geometry, batch after batch.
Key Specifications
- Materials
- Small-diameter aluminum round tube
Key Features
- Forms crank pull handles from thin aluminum tube cleanly
- Tube section stays round at the bend - no flattening
- Drilled mounting holes at the ends survive the cycle
- Red clamp blocks index each tube for matching legs
How Are Thin Aluminum Tube Pull Handles Bent Without Flattening?
Short answer: The tube wraps around a die pin while clamp blocks support it through the bend. This video shows an aluminum handle bending machine forming crank-style U pull handles from small round tube with drilled mounting ends - the finished handles pile up beside the station with round sections, clean bend radii and matching leg lengths.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Manual insertion into red clamp blocks | Tube indexed at the bend line |
| Form | Rotary wrap die, hydraulic stroke | Round-section bend, no flattening |
| Repeat | Second leg at same station | Matching crank geometry |
| Check | Calipers and ruler on the table | Hole and leg positions verified |
Key Applications
- Aluminum crank pull handles for cabinets, drawers and doors
- Thin-tube hardware needing drilled mounting ends
- Enclosure, machine-guard and furniture pulls
- High-count handle batches on a single compact station
Rotary Tube Bending vs. Press Bending Thin Tube
| Criterion | Press bending | Rotary wrap bending |
|---|---|---|
| Tube section at bend | Flattens or wrinkles | Stays round, as shown |
| Drilled end integrity | Often distorted | Holes survive the cycle |
| Leg length repeatability | Re-measured per part | Clamp blocks index each tube |
| Batch rate | Slow | Continuous manual feed |
FAQ
What stock does this machine bend in the video? Small-diameter aluminum round tube, with drilled mounting holes formed at the ends.
Does bending distort the drilled holes? No - the clamp blocks grip away from the finished ends, and the close-ups show round holes and clean tube ends after bending.
Can the station run different handle sizes? Yes - die pins and clamp blocks are changed to match other tube diameters, leg lengths and bend patterns on request.
