How Are 7 mm Automotive Wire Frames Bent in One Cycle?
Short answer: On a CNC 3D wire bending machine. This video shows 7 mm steel rod being fed straight into a rotary bending head that forms an automotive frame shape with hook ends - all bends happen in a single automatic cycle for repeatable, batch-ready parts.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Straight rod feed | 7 mm wire positioned at the die |
| Clamp | Hydraulic-style clamping tooling | Thick rod locked securely |
| Form | Rotary 3D bending head | Frame outline and hook ends formed |
| Verify | Finished parts shown at start | Consistent geometry across parts |
Key Applications
- Automotive wire frames, brackets and retainers
- Seat, trim and luggage rack wire components
- Thick-rod hardware for industrial equipment
- Suppliers replacing slow press-by-press bending
CNC 3D Rod Bending vs. Sequential Press Bending
| Criterion | Press bending | CNC 3D rod bending |
|---|---|---|
| Bends per setup | One at a time | All bends in one cycle |
| Thick rod capability | Large presses needed | Rotary head with clamp |
| Part consistency | Tool wear drift | CNC-controlled angles |
| Changeover | Physical tooling swaps | Program recall |
FAQ
What is the maximum rod size this machine bends? The demonstrated part uses 7 mm steel rod; depending on model and tooling, the series covers wire and rod from fine diameters up to heavy sizes.
Can the machine form hook ends and 3D offsets? Yes - the rotary head bends in multiple planes, so hooks, cranks and offsets are completed without re-fixturing.
Is the material limited to automotive steel rod? No. Mild steel, spring steel and coated rod can be processed with matched tooling and program parameters.
