How Are Flat Aluminum Crank Handles Bent Flat and True?
Short answer: On a rotary wrap-around die with clamp blocks. This video shows a handle bending machine forming flat-bar aluminum crank handles with drilled ends, producing clean, flat bends and repeatable geometry.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Clamp | Block clamp on drilled end | Bar held flat and true |
| Feed | Manual bar insertion | Correct bend position |
| Form | Rotary wrap-around die | Clean flat crank bend |
| Repeat | Handles on the table | Identical handles per batch |
Key Applications
- Flat aluminum crank handles for cabinets and drawers
- Door and enclosure pulls from drilled-end bar
- Hardware shops replacing slow hand bending
- Runs needing flat, true bend lines
Rotary Bending vs. Hand Bending for Flat-Bar Crank Handles
| Criterion | Hand bending | Rotary die bending |
|---|---|---|
| Bend flatness | Twists and marks | Flat, true bends |
| Drilled ends | Can shift | Clamped in place |
| Consistency | Varies | Repeatable geometry |
| Speed | Slow | Fast manual feed |
FAQ
What stock does this machine bend? Flat or oval aluminum bar with drilled mounting ends; the die can be matched to other profiles on request.
How are the ends kept aligned? Clamp blocks hold the drilled end while the rotary die forms the bend, so the legs stay flat and true.
Is the machine easy to run? Yes - feed the bar and trigger the bend, so new operators reach full speed quickly.
