Buckle-Type Outer Frame Production Line for HVAC/VCD/Fire Damper

The fire damper series of equipment mainly consists of: (I) the Frame production line; (II) the blade forming machine; (III) the support bar forming machine; (IV) the leaf spring forming machine; (V) the positive pressure air supply outlet production line; (VI) the positive pressure air supply outlet baffler production line; (VII) the riveting platform; and (VIII) the related complementary molds.  

 (II) Main Process Flows  

The coil is placed on the feed rack and tensioned manually. It is leveled up through the leveling machine and fed to length over the feeding roller powered by the servo motor. It then goes through two pairs of profiling molds and hole molds, to form holes and shear angles for splicing. Then through the guiding board, it enters the forming machine and formed into common-plate flanges by 18 pairs of cold bending rollers. Thereafter, through two pairs of blanking molds and one pair of cutting molds, it turns into a valve body blank with four sides. The cut workpiece is manually folded into a frame and buckled up, to build a complete valve body.

Decoiling → Plate guiding → Leveling → Profiling molds (5 pairs) → Punching rotor shaft holes (16mm) → heat detector hole (20mm) → Cold bending → Profiling molds (for modification) → Cutting to length → Collection rack → Folding into frames manually
