High Speed Flexible Connection Production Line Automatic Hvac Duct Making Machine

Dongguang Hengfu Roll Forming Machine Co., Ltd. presents a fully automatic flexible connector production line engineered for high efficiency, stable performance, and consistent forming quality. This integrated equipment is specially designed for manufacturing flexible connectors using galvanized steel and fire-resistant cloth, combining feeding, punching, roll forming, cutting, and collecting into one smooth workflow. With professional design, reliable structure, and long service life, it has become a preferred production solution for HVAC, ventilation, and construction industries worldwide.

This flexible connector machine supports a wide processing range to meet diverse production needs. It handles galvanized steel sheets with a thickness of 0.3-0.6mm and width of 50-105mm, as well as fire-resistant cloth of 120-450mm, delivering finished products with a width range of 180-600mm. The wide material adaptability and stable production process ensure high compatibility with various project specifications, making it ideal for both mass production and customized orders.

The production line follows a highly efficient automatic workflow: uncoiling → servo feeding & punching → roll forming → punching → cutting → material collecting. Powered by a 3KW main motor and precision cycloidal pinwheel reducer, the equipment achieves a stable output speed of 6-8m/min. The whole line is controlled by a PLC electric cabinet, enabling precise control, easy operation, and reduced labor intensity, while ensuring high productivity and low error rates.

The forming unit is built with industrial-grade components for durability and precision. It features 12 forming stations with rollers made from high-grade Gcr15 bearing steel, finished by CNC machining and coated with 0.05mm hard chrome plating for wear resistance and extended service life. The main shaft uses Cr40 steel with precision finishing and keyway processing, while the frame adopts a welded 80*80 square tube structure with 14mm thick vertical plates to ensure strong rigidity, low vibration, and long-term stable operation.

The complete equipment configuration includes a forming host, four sets of punching and cutting dies, one control system, one servo feeding and punching unit, one hydraulic power unit, two electric uncoilers, and one electric coiler. This fully equipped structure ensures smooth coordination between all parts and high automation. Backed by the professional manufacturing capability and strict quality control of Dongguang Hengfu Roll Forming Machine Co., Ltd., this flexible connector machine offers stable performance, easy maintenance, and excellent cost efficiency for modern production facilities.
