Machine Definition and Core Values

The downpipe machine, scientific name "Metal Downpipe Special Cold Bending Forming Equipment", is like a precision operating industrial symphony orchestra, composing a magnificent symphony of automated production processes such as metal coil unwinding, leveling, cold bending forming, cutting to length, and port processing. It uses cold-rolled steel plates, color coated steel plates, and galvanized steel plates as creative materials, carving out various shapes of drainage pipes such as circular, rectangular, and square, injecting standardized artistic genes into the building roof drainage system.
Compared with the clumsy traditional manual welding and segmented processing techniques, this automated equipment constructs an efficient production loop from raw materials to finished pipes. The production efficiency has increased by 3-5 times, and a single production line can produce 800-1500 meters of pipes per day, just like a precision loom that never stops on an industrial assembly line. Its unique craftsmanship lies in strictly controlling the size error of the pipe within ± 0.3mm, while ensuring a smooth and new surface without scratches or deformations. It can be regarded as the intelligent choice and quality responsibility for modern building materials enterprises to produce downspouts on a large scale.

Core technical features: high precision, high adaptability, high stability

The technical level of the downpipe machine directly determines the quality and production efficiency of the pipes, and its core technical characteristics can be summarized into three points:

1. High precision molding to ensure drainage performance
Through multiple forming rollers and guiding positioning, the roundness error of circular pipe section is ≤ 0.2mm, the diagonal error of rectangular pipe is ≤ 0.3mm; the cutting error of fixed length is ≤± 0.5mm; the polishing forming roller (Ra ≤ 0.8 μ m) is combined with coating protection, and the surface of the pipe is defect free, with a color coating integrity rate of over 99%.

2. High adaptability to meet multi specification requirements
Replace the forming roller set within 2 hours and produce various cross-sections such as circular and rectangular shapes; Suitable for 0.3-1.2mm color coated steel plates, stainless steel and other materials; The touch screen can switch parameters such as diameter and length within 10 minutes, suitable for small batch orders.

3. High stability, reducing production losses
Key institutions are equipped with overload protection and automatic shutdown; Flying saw cutting achieves no tailings, with a material utilization rate of over 98%; The service life of wear-resistant forming rollers exceeds 2 million meters; The soundproof cover design ensures that the operating noise is ≤ 75dB.

Workflow: Automated closed-loop from coil to finished product

Taking the commonly used circular buckle type downspout in civil buildings as an example, the complete production process is as follows, with only one operator monitoring the equipment status throughout the entire process:

1. Raw material feeding: Lift the color coated steel plate coil to the hydraulic unwinding machine, and the tensioning mechanism automatically fixes the center axis of the coil to ensure smooth unwinding;

2. Uncoiling and leveling: The uncoiler unfolds the coil, the multi roll leveling machine eliminates wrinkles in the sheet, and the feeding traction mechanism transports the sheet to the forming system at a speed of 12m/min;

3. Cold bending forming: The sheet enters the forming roller group, undergoes 20 progressive rolling steps, gradually bends into a semicircle, and then continues to roll into a circular pipe prototype;

4. Cut to length: The length detection encoder monitors the length of the pipe, and when it reaches the set value of 4m, the flying saw cutting machine follows suit to cut and form a single downspout finished product;
