Angle iron flange punching and cutting including total 5 parts: Feeding device, major part, cutting device, hydraulic and electric system. PLC control system can improve accuracy , more effective and lower cost.

The 3-roller bending machine features the diamond structure and is used for thicker sheets. The upper roller can be lifted to facilitate plate removal.It is cut into two kinds:symmetric  and asymmetric.

Rotary machine used specialized rolling wheels to process the mental sheets into different shapes covering grooving,envelope line,flattening,cutting ,embossing and round elbow.

With the advantages of reasonable design and structure, high precision and  efficiency, flexible adjustment and convenience. Function: automatic detection coil parameters, decoiler and feeding with one key, automatic adjustment Automatic switching, automatic detection and calculation with safe and reliable

Fire damper machine consists of frame production line,positive pressure air supply outlet production line,blades forming machine,supporting bar forming machine,spring forming machine,riveting platform and so on.

The blade forming machine for fire damper machine adopts PLC control, LCD touch screen, human-computer interface. Realize the interaction between human and Panasonic PLC. The operator can automatically run (programmable control) and monitor the control process through the set program, so as to realize the operator to control the production line and modify the control parameters, and monitor the equipment operation status, operation parameters and fault indication in real time. The length of the work piece can be adjusted. 

The baffler forming machine for fire damper machine adopts PLC control, LCD touch screen, human-computer interface. Realize the interaction between human and Panasonic PLC. The operator can automatically run (programmable control) and monitor the control process through the set program, so as to realize the operator to control the production line and modify the control parameters, and monitor the equipment operation status, operation parameters and fault indication in real time. The length of the work piece can be adjusted.

Fire damper riveting platform consist of frame riveting(four rivets),TDF corner riveter(four rivets),supporting bar riveting(two rivets) and baffler rivets(single rivet).

Air duct production line  Ⅷ is a new type of air duct automatic production line of our company. The U-shaped structure not only saves the production site, but also reduces the delivery time of raw materials. The production efficiency is high (about 20-23 seconds per piece). The department fully automatically realizes the fixed size cutting, beading, automatic cutting ,the notching, single hem forming, pittsburgh forming, TDF flange and the angle iron flange ,automatically forming and bent into ”L“, ”U“, ”口“ shaped duct. Equipped with punching support air, TDF flange hole is optional. Pittsburgh is formed before bending the short side of the large size duct. It has the advantages of high automation, high efficiency, labor saving and material saving.
