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.

A tie bar tensioning system that allows a bending machine operator to removably couple an upper end of a bend die post of the bending machine to a base of the bending machine via a tie bar, and to lock the tie bar in a tensioned position. The tensioning system includes a stationary member and a rotatable member, each with aligned tie bar passages for receiving the one end of the tie bar. Both the stationary member and the rotatable member include respective engagement surfaces, with the rotatable member engagement surface being rotatable relative to the stationary member engagement surface between a released position and a tensioned position whereat the rotatable member is selectively lockable. The rotation of the rotatable member with the rotatable member engagement surface in engagement with the stationary engagement surface longitudinally displacing the rotatable member relative to the stationary member.

The invention relates to a method for roll-bending a profile which comprises at least one cross-sectional region which is formed from a plastics material which is shaped by extrusion. A first and a second bending roller set are provided, each including bending rollers which are arranged in such a way that a passage, which enables guiding of the profile, is formed between the bending rollers of each of the bending roller sets. The profile is bent about a first bending axis and about a second bending axis which is non-parallel thereto, the translations and rotations of the second bending roller set being brought about simultaneously at least at times and/or mutually offset in time in a predetermined sequence.

An assembly for removably securing a tool to an industrial machine. The assembly includes an assembly base portion that may be removably secured to the industrial machine. A tool main body may be integrated with the assembly base portion. A tool attachment unit is provided to transition the assembly between a secured configuration and an unsecured configuration. The tool main body is securely fixed to the assembly base portion in the secure configuration. The tool main body is separable from the assembly base portion in the unsecured configuration. The assembly base portion and the tool attachment unit are configured to accommodate a variety of different tool main bodies according to a desired application.
