12mm Stainless Round Bar Bending Machine | Hydraulic Rotary
Watch a hydraulic rotary bending machine form 12 mm stainless steel round bar into ball-end crank handles in one quick stroke - fast, repeatable rod bending.
Key Specifications
- Materials
- 12 mm solid stainless steel round bar
Key Features
- Bends 12 mm stainless round bar in one quick hydraulic stroke
- Wrap-around rotary die keeps the polished rod surface mark-free
- Bulk-fed straight rods - simple manual loading, no fixtures
- Repeatable bend angles batch after batch
How Is 12 mm Stainless Round Bar Bent Into Crank Handles Fast?
Short answer: On a hydraulic rotary wrap-around die. This video shows a benchtop hydraulic bending machine taking straight 12 mm stainless round bars from a bulk bin and forming them into ball-end crank shapes in one quick stroke - the rod wraps around the die, so bends are sharp, repeatable and free of surface marks.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Manual pickup from bulk rod bin | Correct bend position every time |
| Clamp | Bolted clamp block on the die face | Rod locked without dents |
| Form | Hydraulic rotary wrap-around die | Crank bend completed in one stroke |
| Repeat | Lift finished part, load next rod | Identical parts per batch |
Key Applications
- Ball-end crank handles and levers for machines and covers
- Stainless rod components for furniture and appliance hardware
- High-volume rod bending shops replacing hand benders
- Small-batch runs needing a polished, mark-free finish
Hydraulic Rotary Bending vs. Press Bending of Round Bar
| Criterion | Press bending | Hydraulic rotary bending |
|---|---|---|
| Surface marks | Common on polished bar | None - wrap-around action |
| Cycle time | Slower, multi-hit | One quick stroke |
| Operator skill | High | Low - simple manual feed |
| Part consistency | Varies | Repeatable geometry |
FAQ
What rod sizes can this bending machine handle? The video shows 12 mm solid stainless round bar; dies can be matched to other diameters on request.
Can it bend parts with pre-welded ball ends? Yes - the demonstrated parts carry ball ends, and the open die layout clears them during the stroke.
Does the operator need special training? No. Picking a rod, inserting it and triggering the stroke are the only steps, so new staff reach full speed within a shift.
