An Apparatus For Manufacturing Of Defect Free Damper Blades For The Damper Assembly Used In Thermal Power Plants

Abstract: The invention relates to an apparatus for manufacturing of defect free damper blades for the damper assembly used in thermal power plants, the damper assembly comprising at least a set of damper blades each of the blade having two  blade blocks at both ends to accommodate the rotating shafts and truss plates are provided in between two plates, a plurality of drilled holes enabling plug welding between the truss and the blade plate, the damper blade operable by an actuator through a lever and link mechanism; and a damper frame welded to a rectangular duct, the actuator is being mounted on the drive shaft of the damper assembly for opening and closing of the blades, the apparatus (17) comprising a guide bar (14) to align the edges of a set of blades (12) for subsequent drilling of the blade plates (12); a c-clamp (13) for clamping the aligned edges of the set of blade plates (12); at least a pair of hexagonal screws and nuts (15,16) tightening the aligned and clamped blade plate edges through said drilled holes thereby eliminating alignment by manual hammering including tack-welding via a bridge piece. {FIGURE 5}
