Solid Copper Rod Elbow Bending Machine
Watch solid copper rod blanks bent into smooth elbow fittings on a compact bending machine - tight radius, no kinks, identical parts stacked per batch.
Key Specifications
- Materials
- Solid copper rod with stepped ends
Key Features
- Bends solid copper rod into clean 90-degree elbows
- Rotary die keeps the bend smooth - no kinks or wall collapse
- Stepped spigot ends stay straight and undamaged
- Simple manual feed for fast repeat cycles
How Are Solid Copper Rods Bent Into Smooth Elbow Fittings?
Short answer: On a rotary die bending station. This video shows solid copper blanks with stepped spigot ends being bent into clean 90-degree elbows - the wrap-around die forms the bend without kinking the tube wall or disturbing the pre-machined ends, and finished elbows stack up row after row.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Manual blank insertion | Correct bend position every time |
| Clamp | Die plate with locating holes | Blank held without marks |
| Form | Rotary bending die | Smooth 90-degree elbow |
| Inspect | Part in hand beside the station | No kinks, ends stay straight |
| Repeat | Row beside the die | Identical elbows per batch |
Key Applications
- Copper and brass elbow fittings for fluid systems
- Instrumentation and refrigeration line components
- Fitting makers replacing hand-jaw bending
- Small-batch production needing consistent bend angles
Rotary Bending vs. Compression Bending of Copper
| Criterion | Compression bending | Rotary die bending |
|---|---|---|
| Bend surface | Prone to flattening and kinks | Smooth, round |
| Stepped ends | Often scratched | Stay straight |
| Angle consistency | Varies per operator | Repeatable |
| Cycle time | Slow multi-hit | Fast single stroke |
FAQ
Does the bend kink or flatten the solid copper rod? No - the video shows the finished elbows up close: the rotary die wraps the bend smoothly with no kinks or flat spots.
Can the machine keep the machined spigot ends usable? Yes. The clamp locates the plain body of the blank, so the stepped ends stay straight and ready for assembly.
Which materials and sizes can be processed? The demo runs solid copper rod; tooling can be matched to brass and other diameters on request.
