<p>The subject of the invention is a plumber's bending machine which enables bending of sheet metal up to the angle of 180 degrees. It is characterised in that an upper jaw (2) is bent backwards prior to its clamping into an axle (8) to create a roundness which is a jaw (9); behind the jaw (9), the side is bent in the opposite direction and is turnably clamped in the axle (8) at its end; an additional side (7) is clamped stiffly into the machine's structure and is shaped mirror-invertedly with regard to the jaw (9) and is making another rounded jaw (10). Between the jaw (9) and the jaw (10) towards the axle (8), there is an opening in the angle (b) of between 25 and 75 degrees, preferentially 30 degrees, with the depth (G) of the angle (b) between 5 and 50 mm, preferentially 16 mm.</p> |
