The positive pressure air outlet valve body forming production line consists of material rack,leveling,hydraulicshearing, punching square mouth,punching sharp comer,punching round hole,valve body forming machine,bending machine and hydraulic shearing.It adopts full computer PLC control and touch screen operation,and can be set to any size
according to the operation requirements.The pressure air supply frame frame is fully automatic production,which greatly improves the production efficiency and is suitable for use in fire damper production plants.

The full-automatic fire damper produced by ChenFeng Mechanical CO.Ltd.is a high-eficiency full-automatic production
line independentlyresearched and developed by ChenFeng based on fully absorbing abroad competitors advanced experiences for the current situation of low production efficiency and instabilty of product quality of domestic fire damper manufacturers.It applied new crafts,new techniques and solved affectively many problems brought by traditional welding crafts,the fire damper produced by it doesn't need weld and rust prevention treatment,and guarantees the zinc coating of zinc plate without any
damages ,which conforms to the national environmental protection requirements its fulline achieved standardized,inteligent and high-efficiency production,reduced product period greatly,saving time and labor,and reduced the scrap rate of product ,which is the ideal equipment for batch production of fire damper.
Fire damper production line consistsoframe production line,positive pressure air supply outlet production line,leaf molding machine,support bar molding machine,spring plate molding machine,riveting platform,copper sheathing,square shaft machine, mating molding and other equipments.
