GDF/PDF automatic air duct production line

1. Decoiler

The shaft of feeding device is made of 45# steel, and the upper roller of feeding shaft is covered with rubber.  45# steel is processed by tempering treatment, which has enough strength and rigidity.  The frame and with square tube and channel steel group welding.  Then after aging treatment, so as to ensure the stability in the process of use.  The feeder is equipped with a 1.5KW motor, which is driven by a reduction device.  After the circuit control, it realizes the function of automatic control of discharging, releasing and pointing feeding, which plays a good role in protecting the surface of the sheet material and avoiding the phenomenon that the general discharging machine damages the material edge.

2. Main machine (Leveling,beading,notching,shearing)

(1)Leveling

The leveling machine adopts the general leveling technology and unique structure design, the working roller material 45# steel, after tempering, electroplating and other reasonable process treatment, the surface performance is good, its rigidity, deflection, surface roughness and other mechanical properties greatly improved, thus playing an important role in the leveling of the surface state and flatness of the plate material.

(2)Beading

The beading adopt the shape of five parallel lines, and the pressing tendon ring is made of high quality steel with heat treatment, which can meet the pressing tendons of the steel plate within 1.2mm thickness, and can form the shape with five lines of curvature and angle at one time, so that the steel of the formed plate is greatly enhanced.

(3)Notching

The shear angle part is located at the end of the leveling machine, which can be adjusted freely according to the width of the sheet.  It is very convenient to remove and change the upper and lower dies, and when you need to punch and cut different angles and shapes, you only need to change the upper and lower dies.  The power adopts hydraulic system.

(4)Fixed length shearing

Shearing machine to achieve separate shear plate under the function;  plate material forward to the set shear length, the upper beam pressure, while the shear beam action.  Hydraulic automatic shearing, transmission balance, shearing tool material using high-quality tool material 9Crsi, shear mouth without burrs and tool life, quick replacement, adjusting the shear gap is very convenient.

3. Movable auto Pittsburgh lock forming machine

Pittsburgh lock forming machine adopts new displacement type reel bone, one-time forming Pittsburgh lock, when the sheet material smoothly reaches the set length, Pittsburgh lock forming machine automatically starts from left to right, the sheet material enters Pittsburgh lock forming machine after forming the required Pittsburgh lock shape, when Pittsburgh lock shape is completed ,then touching the limit switch,  the Pittsburgh lock forming machine returns to the original position to complete a cycle.  The sheet enters the 

next flange machine process.

4.20mm & 30 mm Duplex PDF/GDF flange machines,2 sets

(forming width of up to 1500mm adjustable)

Duplex PDF/GDF flange machine consists of two sets of rolls.  When different flanges are needed, it is only necessary to adjust the required flange then it can be used.  Roll by GCr15 steel processing, heat treatment, CNC lathe finishing, roll surface hardness up to HRC58 ~ 60.  forming width of up to 1500mm adjustable, adjust the loosening of the lock nut, shaking the hand wheel to the required width and then lock the nut can be, two sets of rolls set fixed, another set of linear guide, can be adjusted through the nut, screw width.  Two sets of rolls are synchronized by the drive shaft.  So the sheet material through the Duplex PDF/GDF flange machine guide plate into the rolls, complete the flange forming.

5. Servo motor material feeding platform and hydraulic folding

This is a new type of PDF/GDF hydraulic bending machine with a manipulator.  The manipulator consists of fixed frame, manipulator, Yaskawa servo motor, Mitsubishi PLC drive and belt transfer device.  Its function is to convey the sheet material into the bending machine after forming by flange forming machine.  The material is clamped by the manipulator, and the servo motor controls the fixed length feeding to the bending machine.

Hydraulic bending machine, pressing bending are controlled by hydraulic and electrical systems, bending using hydraulic drive, double-acting throttle valve for speed regulation, smooth work, small impact.  When finishing Pittsburgh lock forming, forming flange, the robot will be pushed the sheet to the bending machine and set length position, the lower beam upward compression the sheet, bending machine bend the sheet, complete the plate material bending " "right angle bone shape process, the plate material continues to move forward to the set position, complete various models of bending, after completing the duct from the bending machine then manually removed.  Pressing, bending hydraulic cylinders complete bending with compact structure, great bending effect.
