Duct Manufacture Auto Line V | Auto Duct Line Suppliers - Metmac

Duct Manufacture Auto Line

Duct manufacture auto line is designed for medium to large volume HVAC workshops and is used to work with the coiled metal with weighting up to 6 tons, thickness up to 1,2 mm and minimal duct size 180x180 mm .

The machine provides high efficiency production of air condition rectangular ducts. The production process can be managed by only one operator. The quantity and the parameters of the required products are inserted directly through the Touch Screen of the controller with a convenient and easy to manage interface.

Duct manufacture auto line V has a modular design which allows to use it in different configurations: feeding & straightening of the coiled metal, bending, punching, cutting-to-length, Pittsburgh forming, TDF flange, “C” flange, angle iron flange forming, duct folding and seam closing.

COMPONENTS DESCRIPTIONS

Decoiler

Duct Manufacture Auto Line V 10

The material rack can be placed two volumes of materials, a single volume can be carried 6T. 45# steel pipe, the material is processed by quenching and tempering treatment, with sufficient strength and rigidity. A square tube and welded steel frame, and then through aging treatment, thus ensuring the stability of the use of the process. 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.

Leveling and grooving, punching and cutting device

Duct Manufacture Auto Line V 11

Leveling and grooving

The front is a pair of feeding rollers feed in without slipping, and ensure that the outer surface will not damage the sheet; five leveling roller; a pair of grooving roller, , reinforcement spacing is 5 * 210mm. A pair of roller shaft work location, all outer circle surfaces by the hard chrome plating, which is durable and ensure the outer surface of the sheet will not damage. Adjustment of the adjustment of the roller on the roller is common to both ends of the worm gear and worm drive, in the regulation process to ensure the synchronization of the two ends of the roller, to avoid the occurrence of the phenomenon of running material

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; and the upper and lower die punching replacement is very convenient, need different angles and shapes, only need to replace the upper and lower die.

Punching device on pittsburgh lock and TDF flange hole

Punching hole on flange (pls see product drawing), 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; and the upper and lower die punching replacement is very convenient, need different aperture only need to replace the upper and lower die.

Punching device on supporting hole

Punching support hole (pls see product drawing), one set of mold. The mold consists of a cylinder, a hand wheel is rotated by rotating the screw to adjust punching and punching position of different width plate; and the upper and lower die punching replacement is very convenient, need different aperture only need to replace the upper and lower die.

Cutting

Hydraulic cutter, by two 63mm diameter; cylinder 65mm stroke cylinder, in order to ensure the synchronization of the cut at both ends of the two cylinder moves, using a synchronous shaft through a gear rack drive. Upper and lower scissors using high quality alloy tool steel Cr12MoV, through strict heat treatment and finishing, the edge of the blade sharp, durable, cut out of the work piece with high precision and no burr, no burr phenomenon.

Pittsburgh lock former

Duct Manufacture Auto Line V 12

The whole machine is controlled by the cylinder without piston rod to move, and realize the sheet metal forming process. Cold rolling forming roller adopts GCr15 material, with strict heat treatment and finishing.

Transporter I

Duct Manufacture Auto Line V 13

The circular guide rail manipulator, using aluminum connecting installation cylinder (TN5*80) as the driving force. The sheet reaches the designated position of the feeding platform, servo motor to control the movement of the manipulator, the cylinder drive plate that displacement bite machine joint angle bite, bite after the evacuation board thought material platform II, prepare for the next step, the cylinder manipulator rise back to its original position.

The surface of the conveying roller is galvanized, and the two sides are provided with a retaining device to locate and prevent the running material. The motor adopts the frequency converter to adjust the feed line speed, and the sheet metal is sent to the flange forming device stably and reliably.

TDF and drive cleat flange forming device

Duct Manufacture Auto Line V 14

On both sides of the use of a separate motor control, the use of linear guide rail precision movement, can be adapted to the different width of the plate material on the cold. Two conveyor belts are used in the center to adapt to the cold rolling speed.

A. common plate flange: cold rolling die by the 14 sets of symmetrical two sets of roll. The roller is made of high quality alloy steel, which is processed by heat treatment and numerical control lathe, the hardness of the roller can reach 58~62HRC, and the width of the forming can be adjusted.

B. hook bone (CS bone) flange: cold rolling die by the 8 sets of symmetrical two sets of roll. The roller is made of high quality alloy steel, which is processed by heat treatment and numerical control lathe, the hardness of the roller can reach 58~62HRC, and the width of the forming can be adjusted.

Servo feeding and folding device

Duct Manufacture Auto Line V 15

By the fixed frame, belt drive system and servo system. The servo system by axis high precision linear slide type, servo motors. The sheet on the flange forming device for forming flange after entering the servo feeding platform, then the manipulator device stopped first set up a good position in (to the position according to the production of wind pipe diameter size), sheet by the conveyor belt to the rear folding machine, when the sheet feeding manipulator by servo after the proximity switch, an induction signal to the control system, the manipulator rise in promoting by the lifting cylinder and the servo motor start fast forward to catch the sheet, when the contact switch on the manipulator with the sheet back side, mechanical manual clamp plate according to the design parameters of step forward feeding.

The beam is fixed, the upper pressing, pressing is finished by two with 80 x 40 cylinder bending is done by a 63 * 320 cylinder. Compact structure, good bending effect. Clamp bending by electrical system control. The folding device and the servo feeding mechanism cooperate to complete the bending of the air pipe.
