1. Definition
A 20-stand PV strut / CU channel line (Tianjin electric-power project parameter set) produces U41–82 solar mounting / support channels. Reference flow: ~5T decoil → level/pull → servo feed → punch → ~20-stand form → straighten → servo tracking cut → exit.
Not a triangular BRACKET mill. Not the English 41-series spacer page, not cassette, not the seismic multi-tier package.
2. Technical parameters (TJ20 host)
| Item | Reference |
|---|---|
| Speed | Punch/production ~0–20 m/min |
| Main / cut hyd | Forming host ~55 kW; tracking-shear hydraulic ~5.5 kW |
| Stands / shaft / rolls | ~20 passes; shaft ~φ80; rolls Cr12MoV |
| Drive / PLC | Cast-stand gearbox; Siemens PLC cited |
| Section / feed width | U41–82; feed width ~40–450 mm |
| Thickness / material | ~2–2.75 mm recommended; Q235/Q345 CR or HDG |
| Punch | ~80T press with dies (online punch path) |
| Line blocks | Decoiler, leveler, servo, punch, form, tracking shear, exit |
3. Flying-saw configuration variant
| Item | Flying-saw package note |
|---|---|
| Saw motor | ~18.5 kW |
| Speed | ~0–25 m/min |
| Thickness | ~2–3 mm |
| Punch | May run without online punch path — confirm on that drawing |
Treat flying-saw as a cut configuration on the same family — do not overwrite the 0–20 / 55 kW host table silently.
4. Sibling packages (do not merge params)
| Sibling | Do not import as TJ20-only |
|---|---|
| 41-series | ~0–15 vs ~25; host kW not unified |
| Cassette | ~18.5 / 7.5 kW |
| Seismic | ~25 or ~60 kW document tiers |
5. Buyer FAQ
Is 55 kW the same as seismic 60 kW?
No. Keep seismic document tiers on the seismic page.
When is 0–25 m/min correct?
On the flying-saw configuration note — label it; do not replace 0–20 without saying so.
Feed width?
About 40–450 mm in the TJ20 parameter FAQ.
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.
