HVAC duct line VI,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,pittsburgh forming, TDF flange and the angle iron flange ,automatically forming and bent into ”L“, ”U“, ”口“ shaped duct. Equipped with punching support air, common plate flange hole is optional.It has the advantages of high automation, high efficiency, labor saving and material saving.

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.

暖通空调等离子切割机主要由主机系统及其配套软件系统组成。电气控制系统由计算机控制，并配备了先进的切割软件，常用于各种类型的风管封堵。

The bending pipe welding machine is suitable for the welding application of the inner and outer arc of the stamping attachment of the land circular air pipe. The welding control unit and other aspects of the man-machine interface of the equipment are independently developed and designed, including the important welding elements such as welding current and speed,and the digital display of the man-machine interface is fully realized.And for the welding characteristics of galvanized sheet steel, in the welding control of the design of a unique welding curve, so that it can be more reliable to complete the professional needs of galvanized sheet welding.

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.

Theconducive electrode of the welding machine adopts South Korea's high conduetivitycopper eleclrode malerial, which makes the welding current uüilization ratio noreefficient. The important welding elements sucl as welding piessure realize the digialdisplay of man-machine interface, and acaiding to the welling characterisics of galvanizec sheet steel. a unique welding curve is designed in welding control so as to more reliably complete the professional needs of gelkanized shee welding.
