Semi Duct Manufacture Line

HVAC Duct manufacture auto line III is a high performance equipment with modern design and sophisticated automation system. It is designed for small to medium volume workshops and is used to work with the coiled metal with weighting up to 6 tons, maximum coil width 1250mm or 1530mm, thickness up to 1,2 mm galvanized steel and minimal duct size 180x180 mm .
LOCFOME’s semi-auto duct production line III can drive blanking for the duct. Meanwhile, it’s very suitable for multi-production line TDF/angle steel/ inserted flange forming; the angle steel flange and inserted can be bent into square-shaped pipe automatically. One operator is enough to manage the production process. The quantity and the detail parameters of the required ducts are inserted directly through the Touch Screen of the controller with a convenient and easy to manage interface. And its special modular design allows auto-line III upgrade to auto-line V, which can reduce our clients cost and minimize the change for imperfections that can affect operational effectiveness and ease of installation.
Our Auto-line III provides standardization and improvement of the duct manufacturing process, helping our customers save material and labor costs. We have developed strong customer ties by actively seeking client feedback to improve our service and strengthen client relationships. This approach has allowed us to cultivate strong customer bonds.

 

Basic Information

Descriptions

Duct automatic production line III is a mature product of our  company. This line as the essential square duct machine is mainly used in scaling& blanking duct parts, punching and folding . It can scale and blank for TDF and TDC duct, and it can be combined with TDF flange machine T12, TDC flange machine T20, T30 or T40, Pittsburgh lock machine and seaming machine (duct zipper), plus angle iron to manufacture ducts.

Not only worked in HVAC industry, it is also suitable for processing in light industries like cabinet, appliance, automobile and elevator, etc.  

Duct auto-line III is used for large-scale production, it transforms the raw material into a semi-finished product through four main stages – Uncoiling, Leveling & Grooving, PunchingShearing and Folding. The final result is a product with excellent finish, precision, rigidity and stability.

 

Working Flow:

De-coiler---Feeding---Leveling and grooving---Notching---Punching---Shearing---Folding

 

Feeding Frame (four de-coiler)

The material rack can be placed two volumes of materials, a single volume can be carried 6T. 45# steel pipe.  The rack is equipped with a 1.5Kw motor, the worm gear driving device, a control circuit, realizes the automatic control of feeding, discharging and move the feed function on the sheet surface plays a very good protective effect, avoids feeding machine damage material edge phenomenon. User refueling as long as the feeding shaft hanging down from the whole discharge rack, into the roll material to be used in the inner core, is placed, coil has the advantages of simple operation, ease of refueling. Put rack feeder for multi roll production occasions, convenient conveying materials.

de-coiler

Main Body (feeding-leveling-grooving-notching-punching-cutting)

Feeding: The front is a pair of feeding rollers feed in without slipping, and ensure that the outer surface will not damage the sheet;

Leveling and Grooving: Five leveling roller; a pair of grooving roller, , reinforcement spacing is 6 * 230mm.

Notching: Notching square (37mm) and shape (3mm), total four pieces of mould. Each mold consists of a bore 50mm stroke 30mm cylinder, and the hand wheel is rotated by rotating the screw to adjust the different width of the plate shear angle and shear angle depth.

Punching: Punching hole on flange, two sets of mold. Each mold consists of a cylinder, a hand wheel is rotated by rotating the screw to adjust punching and punching position of different width plate

Shearing: The hydraulic cutter, equipped with two 63mm diameter cylinders, 65mm stroke, to ensure the synchronization of the cut at both ends of the two cylinder moves, using a synchronous shaft through a gear rack drive.

Folding device: twoФ100×50 cylinders have adopted for the clamping process, oneФ63×320 cylinder for the bending. Through fixing the down beam, and moving the up beam to achieve this fasten process, this tightly structure assure the bending accuracy. This clamping and bending processes are electric controlled.
