Product Description

1. Equipment Definition  
The Downspout Roll Forming Machine is an automated production line that transforms metal coils (galvanized steel, aluzinc, color-coated sheets) into rectangular/square drainage pipes via **continuous cold roll forming**. Designed for manufacturing building roof gutters and vertical downspouts.  
2. Core Components & Workflow  
| Module            | Function                                                                 | Key Technology             |  
|------------------------|-----------------------------------------------------------------------------|--------------------------------|  
| 1. Decoiling & Leveling** | Hydraulic auto-feeding, material stress relief                              | Servo tension control (±2%)    |  
| 2. Punching/Embossing**  | Precision drainage hole punching (round/slot) + stiffening ribs             | Pneumatic punching (≤120 strokes/min) |  
| 3. Roll Forming  | 12-18 precision rollers progressively form rectangular profiles (80×60mm~150×100mm) | Progressive bending (springback ≤0.3°) |  | 4. Seam Locking    | Automated hemming for leak-proof joints                                     | European hidden-lock (tensile ≥5kN) |  
| 5. Cutting         | Hydraulic/flying saw cutting (±0.5mm length tolerance)                      | Encoder synchronization        |  
| 6. Auto-Stacking   | Counting and palletizing (horizontal/vertical)                              | Pneumatic robotic arm          |  

3. Technical Specifications  
| Parameter       | Standard                                 | Premium Option              |  
|---------------------|---------------------------------------------|--------------------------------|  
| Material        | Galv. steel (0.4-1.0mm), color steel (0.5mm), aluminum (1.2mm) | Stainless steel (0.6-1.5mm)    |  
| Speed           | 10-25 m/min                                 | 30-40 m/min (servo-driven)     |  
| Profile Size   | Rectangular: 60×40mm~120×80mm<br>Square: 50×50mm~100×100mm | Custom sections (tooling change) |  
| Cutting Accuracy| ±1.0mm                                      | ±0.3mm (laser-guided)          |  
| Waterproof Std. | EN 612 (wind load ≥1.5kPa)                  | ASTM B370 pressure test        |  

4. Key Advantages  
1. Leak-Proof Integration  
  Double-hem locking (no rivets/adhesives), permanent sealing  
   Roller-polished interior (Ra≤1.6μm), minimizes debris buildup  
2. Enhanced Structural Integrity  
   Optional stiffening rib unit (30% anti-deformation boost)  
   Supports multi-layer pipes (sound/thermal insulation)  
3. Eco-Efficiency  
   3x lifespan vs. PVC pipes (25+ years weather resistance)  
   98% material utilization (near-zero waste)  
5. Applications  
| Building Type      | Recommended Profile      | Special Requirements         |  
|------------------------|------------------------------|--------------------------------|  
| Residential        | 80×60mm rectangular (0.5mm galv.) | Woodgrain/copper-color coating |  
| Commercial Complex | 120×80mm square (0.8mm alum.)  | Typhoon-resistant ribs          |  
| Industrial Plant   | 150×100mm rectangular (1.0mm steel) | Acid-rain coating (PVDF)       |  
| Heritage Restoration**| Custom antique patterns       | Handcrafted copper texture      |
