The subject of the invention is a sheet metal bending machine that allows bending of a sheet metal up to an angle of 180°. It is characterized in that an upper jaw (2) is bent backwards prior to being fixed into an axle (8) and has a rounded part, which is a jaw (9); after the jaw (9), the cheek is bent to the opposite direction and in its end rotatably fixed into the axle (8); an additional cheek (7) is stiffly fixed to the framework of the machine and is formed in a mirror inverted way to the jaw (9) and forms a second rounded jaw (10). Between the jaw (9) and the jaw (10) towards the axle (8) there is a gap in an angle (b) between 25° and 75°, preferably 30° and a depth (G) of the angle (b) measures from 5-50 mm, preferably 16 mm. |
