APPARATUS FOR MANUFACTURING A METAL PLATE FOR A DUCT, INCLUDING MESH-TYPE BEADS

Document Type and Number:

WIPO Patent Application WO/2011/068353

Kind Code:

A2

Abstract:

The present invention relates to an apparatus for manufacturing a metal plate for a duct, including mesh-type beads, wherein the mesh-type beads are formed into a grid pattern with regular convexes and concaves on the surface of the metal plate for a duct to increase the strength of the duct, to thereby reduce the thickness of the metal plate for the duct and the cost of manufacturing the duct, and to improve the outer appearance of the duct. The apparatus of the present invention comprises: a frame (F) formed by connecting metal pieces to form a box shape; roll stands (F2) arranged upright on the upper surface of the frame (F) and spaced apart from each other by a predetermined spacing; upper and lower bead-processing rollers (2, 4), the ends of which have respective shafts (S1, S2) coupled to the roll stands (F2), and on the outer surfaces of which mesh-type beads are formed into convexes and concaves; a supply unit (100) consisting of a plurality of idle rollers (110) and arranged behind the upper and lower bead-processing rollers (2, 4) to stably supply metal plates; first and second gears (S1-1, S2-2) coupled to the respective shafts (S1, S2) of the upper and lower bead-processing rollers (2, 4); a pulley (76) coupled to the second gear (S2-2); and a driving unit (7) having a driving motor (72) connected to the pulley (76) via a chain (74).
