The square downspout forming machine is a specialized cold bending equipment for building roof drainage systems. It continuously rolls color coated/galvanized coils into square/rectangular downspouts (commonly 80 × 55mm, 100 × 80mm), which are used for external wall rainwater drainage in factories, warehouses, villas, etc. It has high automation, precise size, and beautiful finished products.

Equipment composition

• Uncoiler: carrying coil material (inner diameter 508mm, outer diameter ≤ 1200mm), pneumatic brake, automatic feeding.
• Forming host: 14-20 rows of rollers (45 # steel plated with hard chrome, HRC58-62), gradually cold-formed into square tubes, ensuring 90 ° right angles and straightness.
• Bite/lock mechanism: The side of the square tube is bite sealed, waterproof and leak proof, and does not require welding.
• Hydraulic flying shear: servo fixed length cutting, with a flat and deformation free cut, and a length accuracy of ± 0.2mm.
• PLC control cabinet: touch screen+PLC, parameter memory, automatic counting, length measurement, alarm.
• Discharge rack: Finished product receiving, stacking, optional automatic palletizing.

Core parameters (mainstream 80 × 55mm)

• Applicable materials: Color coated sheet (PPGI), galvanized sheet (GI), aluminum sheet, stainless steel sheet
• Material thickness: 0.4-0.8mm (commonly 0.5-0.6mm)
• Finished product specifications: 80 × 55mm (standard), 100 × 80mm, custom size
• Raw material width: 330mm (compatible with 80 × 55mm)

Performance characteristics

• Accurate molding, neat appearance: Multiple passes of rolling mill gradual molding, clear square tube corners, flat surface, good straightness, and beautiful installation.
• Waterproof sealing, maintenance free: lock edge interlocking structure, no screws, no welding, waterproof and anti-seepage, with a service life of over 20 years.
• Efficient and stable, high production capacity: Continuous automated production, fast speed, low failure rate, suitable for mass production.
• Universal material, high cost performance: compatible with various thin metal plates, one machine for multiple uses, reducing procurement costs.
• Easy to operate, intelligent and controllable: touch screen settings for length and quantity, automatic operation, beginners can get started in 1 hour.
• The incision is flat and free of deformation: the flying shear and guide mechanism ensure that the pipe mouth does not deform after cutting, and the connection is tight.

• Molding speed: 8-15m/min, daily production capacity of 800-1200m
• Host power: 7.5kW (variable frequency); Hydraulic station: 3kW
• Roll shaft diameter: 75mm (solid 45 # steel, heat-treated)
• Transmission mode: chain/gear transmission, stable operation
• Dimensions: Approximately 7m x 1.2m x 1.5m; Weight: Approximately 4-5 tons
• Control: Delta/Schneider PLC, Omron encoder
