System Architecture: How 31 Rollers Deliver Precision
The 31-roller forming architecture is the engineering heart of this machine. Each roller station applies a calculated incremental bend angle, gradually transforming flat strip steel into the finished cable tray profile without inducing material stress or spring-back deviation.
Progressive Forming Stages
1. Entry Leveling (Rollers 1–3)
Incoming Q235B strip at 1.2–2.0mm is flattened and aligned for consistent perforation registration.
2. Hydraulic Perforation Station
The hydraulic station, powered by 46# hydraulic oil, drives the punching dies. Hole spacing and pattern are synchronized with the roller feed rate through the Delta/Schneider PLC.
3. Edge Forming (Rollers 4–12)
Side walls begin their upward bend progression. The 18# hypoid gear oil in the transmission ensures smooth torque delivery at every station.
4. Profile Completion (Rollers 13–25)
The tray cross-section takes its final shape. Each roller pair maintains ±tolerance on wall height and flange geometry.
5. Calibration & Sizing (Rollers 26–31)
Final rollers lock in dimensional accuracy. The 3-meter cut-to-length system triggers automatically at the programmed length.
Material Science: Optimized for Q235B Steel
The feeding system is engineered for three grades of strip steel commonly used in cable tray production:
| Material | Characteristics | Best For |
| Q235B Cold-Rolled Strip Steel | Superior surface finish, tight thickness tolerance | Indoor commercial trays, visible installations |
| Hot-Rolled Strip Steel | Higher yield strength, economical per ton | Heavy-duty industrial trays |
| Galvanized Steel | Pre-coated corrosion resistance | Outdoor / humid environment applications |
The 194–814mm feeding width accommodates virtually all standard cable tray sizes, making this a single-line solution for diverse product catalogs.
Energy Efficiency: The Hidden Margin Driver
The energy-saving design is not a marketing claim — it is a mechanical reality. The hydraulic station operates on a load-sensing principle: power draw scales with actual punching demand rather than running at constant maximum. For manufacturers running multi-shift operations, this directly reduces per-tray production overhead.
