A tube bending tool (1) comprising support surfaces (2, 2′, 2″), between said surfaces a tube (3), to be bent, is placed. A pressure exerting unit (6) with an extension (8) displaceable towards the tube (3), where a convex, bent bearing surface (10) is provided in order to press against the tube (3) when said extension (8) delivers a force from the pressure exerting unit (6). The front portion (9) comprises elongated elements (12, 12′). The outer ends of the elongated elements (12, 12′) comprise displaceable and movable support elements which press on the outer surface of the tube. The inner ends (13, 13′) of the elongated elements are cross-laid and movable, so that they during bending, press in a direction towards the center of the bending radius of the tube (3), at the same time as different radii of the bend (5) can be provided on different places. There is also an optional limiting means for bends over 90 degrees. |
