Rod Bending Machine | Z-Hook Parts, Caliper Check
A rotary bending machine forms double-bend Z hooks from stainless rod - diameters checked with calipers, clean bends, matching parts pile up.
Key Specifications
- Materials
- Stainless steel round rod
Key Features
- Forms two clean 90-degree bends per part at one station
- Digital calipers verify rod diameter before the cycle
- Red clamp blocks index each rod for identical legs
- Bend radii stay tight and consistent part after part
How Are Double-Bend Z Hook Parts Bent Consistently?
Short answer: Two indexed 90-degree strokes on a rotary die, with the rod checked by caliper first. This video shows a bending machine forming Z hook parts from stainless round rod - the operator verifies the stock diameter, feeds each rod into the red clamp blocks, and the wrap die produces matching double-bend hooks that pile up beside the station.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Check | Digital caliper on rod stock | Correct diameter confirmed |
| Feed | Manual insertion into clamp blocks | Rod indexed at each bend line |
| Form | Rotary wrap die, two strokes | Clean double-bend Z geometry |
| Batch | Finished hooks piled on the table | Matching legs and angles |
Key Applications
- Z-shaped hooks, brackets and connector parts in rod
- Stainless hardware for fixtures, racks and equipment
- Small double-bend parts needing verified stock sizes
- Fast batch runs on a compact single station
Indexed Rotary Bending vs. Free-Hand Rod Bending
| Criterion | Free-hand bending | Indexed rotary bending |
|---|---|---|
| Leg length match | Varies per part | Clamp blocks repeat position |
| Bend angle | Operator dependent | Die-limited 90 degrees |
| Stock verification | Skipped | Caliper check shown |
| Batch consistency | Low | High - parts interchangeable |
FAQ
What does the caliper check accomplish? It confirms the incoming rod diameter matches the tooling, so bend radius and leg springback stay consistent across the batch.
How many bends make one Z hook part? Two opposite 90-degree bends at the same station - the rod is re-indexed between strokes.
Can the machine run other rod sizes and shapes? Yes - die pins and clamp blocks are matched to your diameter, leg lengths and bend pattern on request.
