Car Seat Backrest Wire Bending Machine | 6 mm Steel Rod
Watch a CNC 3D wire bending machine form 6 mm steel wire into car seat backrest frames in one automatic cycle - clean 3D bends, hook ends, repeatable output.
Key Specifications
- Materials
- 6 mm steel wire rod
Key Features
- Forms complex 3D seat frame shapes in a single cycle
- Rotary bending head reaches multiple bend planes without re-fixturing
- CNC program stores each frame geometry for repeat runs
- Clean hook ends positioned accurately every part
How Are Car Seat Backrest Wire Frames Bent in One Cycle?
Short answer: With a CNC 3D wire bending machine. This video shows 6 mm steel wire being fed straight and wrapped around a rotary bending head that forms every bend plane of a seat backrest frame - including the hook ends - in one automatic cycle, no re-fixturing between bends.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Straight wire feed with guide rollers | Wire delivered to exact bend position |
| Form | Rotary 3D bending head | Multiple bends in different planes, one cycle |
| Program | CNC touch-screen control | Stored geometry per frame design |
| Finish | Automatic part ejection | Matching frames with square hook ends |
Key Applications
- Car seat backrest and headrest wire frames
- Automotive trim and reinforcement wire parts
- Furniture frames of similar 3D wire geometry
- Component suppliers replacing multi-station press bending
3D Rotary Bending vs. Multi-Press Bending for Seat Frames
| Criterion | Multi-press bending | CNC 3D rotary bending |
|---|---|---|
| Setup for a new frame | Several dies, several presses | Program change only |
| Bend planes per cycle | One | Multiple |
| Positional error build-up | Accumulates between stations | Single clamping reference |
| Tooling cost | High | Low - one bending head |
FAQ
What wire size can this machine bend for seat frames? The video shows 6 mm steel wire; the same platform covers roughly 3-12 mm depending on the bending tool set.
Can it form the hook ends at both sides of the frame accurately? Yes - the CNC axes index the wire after each bend, so both hook ends land at the programmed length every cycle.
Is changing to a different frame design slow? No. A new part is a program plus a matched die disc; changeover is done in minutes, not by swapping presses.
