Aluminum Frame Handle Bending Machine | Rect Rings
A rotary handle bending machine forms rectangular recessed handle frames from aluminum square profile - four clean bends per frame, rows of matching parts.
Key Specifications
- Materials
- Aluminum square hollow profile bar
Key Features
- Forms complete rectangular handle frames from square profile
- Four clean corner bends produced at one station
- Clamp blocks index each profile for matching frame sizes
- Hollow square section stays true - no crushing at corners
How Are Rectangular Recessed Handle Frames Bent From Square Profile?
Short answer: Four corner bends at one rotary station. This video shows a handle bending machine forming rectangular recessed handle frames from aluminum square hollow profile - the operator feeds the bar into red clamp blocks and wraps each corner around the die pin, producing matching frames with clean corners and an uncrushed hollow section, shown in silver and black finishes.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Manual insertion into clamp blocks | Profile indexed at each corner line |
| Bend | Rotary wrap die, hydraulic stroke | Clean 90-degree corner, section true |
| Repeat | Three more corners at same die | Closed rectangular frame |
| Batch | Frames laid in rows on the table | Matching sizes part after part |
Key Applications
- Recessed pull handles for drawers, doors and panels
- Rectangular frame handles in aluminum square profile
- Cabinet, machine-guard and enclosure hardware
- Mixed-finish batches (bare, black, silver) on one station
Four-Bend Rotary Forming vs. Multi-Stage Press Tooling
| Criterion | Multi-stage press | Rotary four-bend forming |
|---|---|---|
| Corner quality on hollow profile | Crease/crush risk | Die radius keeps section true |
| Tooling per frame | Several stations | One die set |
| Frame size change | New tooling per line | Re-index clamp blocks |
| Batch layout | Bulk bins | Neat rows, as shown |
FAQ
What profile is used for these handle frames? Aluminum square hollow profile bar, bent into rectangular recessed handle frames.
How many bends make one frame? Four corner bends at the same station - the operator indexes the bar in the clamp blocks after each stroke.
Can the machine run coated or blackened profile without marks? The video shows black and silver frames from the same die; the wrap forming keeps the visible faces clean of clamp marks.
