1. Definition
A slotted angle / roll-punch line decoils strip, roll-punches (rotary/roll punch) a repeating hole pattern, then forms slotted angle / shelf-angle type sections. It is a pre-punch integrated host — not a post-punch-only line and not a pure slitting/CTL line.
2. Technical parameters (Chinese recommended tier)
| Item | Chinese tech-note reference |
|---|---|
| Product | ~25 mm width × ~1 mm thickness |
| Speed | ~50 m/min |
| Main motor | ~5.5 kW |
| Shaft / dies | Shaft ~φ100 (45Cr QT); punches DC53 HRC61–63 |
| Control | Industrial PC + PLC + inverter |
| Hydraulics / footprint | Not listed on that note → blocked (do not invent) |
| Core blocks | Decoiler + roll-punch unit (short Chinese BOM) |
3. English India quotation tier (do not merge)
| Item | English quote notes |
|---|---|
| Width / thickness | ~70 mm / ~1.0–1.2 mm GI |
| Speed | ~0–60 m/min (incl. cutting process language) |
| Motors | Rotary punch ~15 kW; form ~11 kW; cut hyd ~5.5 kW + servo ~3 kW; decoiler hyd ~5.5 / motor ~3 |
| Shafts / stands | Punch shaft ~φ150; form shaft ~φ60 solid; ~12 form stands |
| Cut tolerance | ~±1 mm / 3 m cited |
Australian operation manual thickness examples (e.g. T=2.0 / T=0.8) are operator notes — not the product specification band.
4. Applications
- Slotted angle / shelf angle production with repeating hole patterns
- Projects that choose rotary punch for high-speed simple hole maps
Complex hole maps may need CNC punch instead of rotary — confirm on the drawing.
5. Buyer FAQ
Is 50 m/min the same as 0–60?
No. They belong to different quotation tiers — label the source.
Is this a post-punch line?
No. This host hangs on the pre-punch / roll-punch family evidence.
Can I invent hydraulic kW for the Chinese note?
No — that field is blocked on the Chinese tech note.
6. Verification notes
- Publish only numbers that appear on the named FAQ / parameter sheet for this leaf.
- When two source documents disagree, list both tiers with labels — do not average.
- Host ratings stay separate from auxiliaries (curving, stacking, offline presses) unless the FAQ bundles them.
- Directory identity is fixed; open fields stay blocked until a proposal confirms them.
Final ratings follow the named technical proposal. Price and lead time are out of scope.
