Abstract (en)
[origin: WO2018236314A2] The present invention relates to a method of flanging a ventilation canal edge used for flanging the edges of quadrangular air ducts and a machine for this method, the square canal (K) and / or the elbow joint (D) are positioned on the carrier grid (7), to present in starting position (10) where the sheet metal (S), is pressed between benging form (6.5) and the forming thread form (4.1) from the starting position (10) by pressing with the help of the pressure group (1), the thrust group (2) and the miter group bringing into first position (20) then to the second position (30) by turning 90 degrees together with the sheet metal (S) brought to the first position (20), the bending piston (9.4) and the press plate (1.1) to the third position (40) by being pressed between the steep pressure plate (5.5) and the aid standing (6.4) to the third position (40) by means of the sheet metal (S), the inner mold (8.1) and forming the flange (60) at the mouth portion of the square canal K and / or the elbow joint(D) by pressing the tilt piston (3.1) and the standing and tilting joint (3.3) of the sheet metal (S) brought into the fourth position (50).
