China HVAC Auto Duct Production Line 3

The auto duct production line III is composed of a material rack, a leveling rib unit, a burr punching unit and a square mouth punching unit, a cutting unit and a folding unit. The standard configuration is the tip punching unit and the square punching unit required for the TDF flange duct, and the square port punching unit can also be used to produce the TDC flange. The folding unit can process the right angle bone that matches the joint port, or bend the sheet into a “mouth” or “L” shape, and then use the lock forming machine to machine the joint port for the TDC flange duct . Greatly improve the utilization of the board, reduce labor intensity and reduce labor cost .

The control part of the production line adopts full computer control. The control system has a closed-loop feedback system, and the accuracy and stability are obviously improved. Its maximum working speed is 16 m / min. The length error is ±0.5MM and the diagonal error is ±0.8MM. The system can meet the capacity of 1000M2 square duct for single shift. MYT auto duct line also can be customized according to client requirement , like voltage , spare parts , color or machine’s deign

“Duct Line 3” typically refers to the auto duct production line 3, consisting of four main stages. The auto duct line 3 is composed of:
① Uncoiler (material rack)
② Leveling and Beading Machine
③ Hydraulic Punching Machine (for notching corners and making square holes) and Hydraulic Shearing Machine
④ Hydraulic Bending Machine

The processing flow and coordination of each stage are as follows:

① Uncoiling Stage: The material rack feeds coil material into the subsequent equipment, providing raw material for further processing.

② Leveling and Grooving Stage: The leveling and beading machine flattens the coil material and creates reinforcing beads. This prevents material waste during processing and ensures the material’s flatness and strength, laying a solid foundation for the following punching, shearing, and bending steps.

③ Notching and Cutting Stage:

Notching: The hydraulic punching machine performs corner notching and square hole punching, preparing the sheet for further bending and flange connection.

Cutting: The hydraulic shearing machine cuts the sheet from the coil into the required lengths.

④ Folding Stage: The hydraulic bending machine folds the cut sheet into duct shapes, forming the final air duct structure.
