Macchina formatrice di fasci di tubi d'acciaio: trasferimento a catena e formatura di fasci esagonali alla fine del laminatoio.

**Sintesi esecutiva**
> This clip shows a steel tube bundle forming line at the end of a tube mill. Tubes run out on a roller table, a chain deck moves them sideways, and a yellow forming station gathers them layer by layer into a tight hexagonal bundle ready for strapping. The footage was shared with us; our equivalent solution forms and straps tube bundles in the same way, with the bundle shape, tube count and strapping matched to your mill.

Sommario

Cosa mostra il video

| Passo | Cosa vedi |
|---|---|
| Run-out | Cut tubes travel along a long roller table in the mill bay |
| Transfer | A chain deck carries the tubes sideways, one layer at a time |
| Forming | A yellow V-shaped forming station with side arms gathers the tubes |
| Bundle | Tubes build up into a hexagonal bundle held in the former |
| Discharge | The formed bundle sits ready for the strapping step |

Perché un fascio esagonale

- **Stable shape.** In a hexagon each tube rests on the tubes below, so the bundle does not roll apart.
- **Dense pack.** A hexagon holds more tubes for a given width than a square stack of round tubes.
- **Even strap load.** The strap bears on a near-round outline, so the load spreads over the outer tubes.
- **Easy lifting.** A compact bundle is easier to lift with slings and to stack in the yard.

Formula del fascio esagonale e conteggio dei tubi

**Worked example (illustrative).** A full hexagon with n tubes on each side holds 3n(n − 1) + 1 tubes.

| Tubes per side (illustrative) | 3n(n − 1) + 1 | Tubes per bundle | Widest row, 60 mm tubes |
|---|---|---|---|
| 4 | 3 × 4 × 3 + 1 | 37 | 7 × 60 = 420 mm |
| 5 | 3 × 5 × 4 + 1 | 61 | 9 × 60 = 540 mm |
| 6 | 3 × 6 × 5 + 1 | 91 | 11 × 60 = 660 mm |

Per tubi da 60 mm (a titolo di esempio) con 5 tubi per lato, il fascio misura (2 × 5 − 1) × 60 = 540 mm lungo la fila più larga.

Quindi, passando da 5 a 6 tubi per lato, si aggiungono 30 tubi per fascio; utilizziamo questo dato per impostare il peso del fascio in base al limite della gru.

Ciò che abbiamo stabilito per mille

| Impostazione | Dipende da |
|---|---|
| Former size | Tube diameter and tubes per bundle |
| Bundle shape | Hexagonal, square or round, per your yard |
| Transfer pitch | Tube diameter and mill speed |
| Strapping | Number of straps, steel or PET strap |

Lista di controllo per la selezione

- [ ] Tube diameter and wall thickness.
- [ ] Tube length range.
- [ ] Tubes per bundle and bundle shape.
- [ ] Bundle weight and crane limit.
- [ ] Mill output in tubes per minute.
- [ ] Straps per bundle and strap type.

Sicurezza

- Keep clear of the chain deck and the forming arms while the line runs.
- Lock out the former before clearing a jammed tube.
- Use guarding and light curtains around the forming station.
- Per i mercati CE, la macchina è progettata secondo le norme ISO 12100 e EN 415-10.

FAQ di ingegneria

Q: What does a tube bundle forming machine do?
A: It gathers cut tubes from the mill into a fixed bundle shape, ready for strapping.

Q: Why a hexagonal bundle?
A: Each tube rests on the tubes below, so the bundle is stable, dense and easy to strap.

Q: How many tubes are in a hexagonal bundle?
A: 3n(n − 1) + 1 for n tubes per side; 61 tubes for 5 per side in the worked example.

Q: Can it make square bundles?
A: Yes. We set the former for hexagonal, square or round bundles per your yard.

D: È possibile realizzare questa configurazione?
A: Yes. We build equivalent tube bundle forming lines matched to your mill speed, bundle shape and strapping.

Q: What comes after forming?
A: The formed bundle goes on to strapping, then to the yard.

D: Quali norme si applicano?
A: Per i mercati CE, ISO 12100 e EN 415-10.

Passo successivo

Il processo di assemblaggio di una linea di formazione di fasci tubieri avviene in tre fasi:

1. **Submit your layout drawing** with tube sizes, lengths, tubes per bundle and mill speed, to **info@fhopepack.com**.
2. **Riceverai una proposta entro 48 ore** con i dati e il layout della macchina.
3. **Book a site survey** so we confirm the mill run-out layout.
