Rod Bending Machine | 90-Degree L Parts at Speed
A rotary bending machine forms 90-degree L parts from stainless round rod - one indexed stroke per elbow, neat rows of matching hardware parts at the station.
Key Specifications
- Materials
- Stainless steel round rod
Key Features
- One indexed stroke forms each clean 90-degree elbow
- Clamp blocks set leg lengths for interchangeable parts
- Finished parts laid in rows - straight, matching lines
- Square and calipers at the bench verify angles quickly
How Are Rows of Matching 90-Degree Rod Elbows Made So Fast?
Short answer: One stroke per part on an indexed rotary die. This video shows a bending machine forming 90-degree L parts from stainless round rod - the operator drops each rod into the clamp blocks, the rotary stroke wraps a clean elbow, and the finished parts line up in straight rows on the table, squared and checked with bench tools.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Manual drop into clamp blocks | Rod at the marked bend line |
| Form | Rotary die, single hydraulic stroke | Clean 90-degree elbow |
| Check | Square and calipers on the table | Angle and legs verified |
| Stack | Parts laid in rows | Interchangeable batch output |
Key Applications
- L brackets, elbows and connector parts in stainless rod
- Furniture, rack and fixture hardware production
- High-count single-bend batches on one station
- Replacement of slow jig-and-hammer hand bending
Single-Stroke Rotary Bending vs. Multi-Hit Press Bending
| Criterion | Multi-hit press | Single-stroke rotary |
|---|---|---|
| Bend angle | Springback correction needed | Die-limited 90 degrees |
| Cycle time | Several hits per part | One stroke per part |
| Leg consistency | Re-measured | Clamp blocks index each rod |
| Batch layout | Mixed quality | Straight matching rows |
FAQ
What parts are produced in this video? Single-bend 90-degree L parts (elbows) from stainless steel round rod.
How is the bend angle kept accurate? The rotary die wraps the rod to a fixed angle in one stroke; the bench square and calipers shown are used for quick verification.
Can the machine handle other rod sizes? Yes - tooling is marked and matched per size (an M12 die set is visible); other diameters use corresponding blocks and pins.
