Definitions
- the present invention relates to a tool on pipe or profile bending machines.
- the present innovation is therefore based on the task of proposing a possibility with which the service life of the tools on pipe and profile bending machines can be extended.
- a tool such as a smoothing tool, mandrel or guide rails, with the features of claim 1.
- a wrinkle smoothing device a dome, rollers, guide aids, dies or guide rails is then coated with a layer of molybdenum or a molybdenum alloy.
- This layer can be less than 0.1 mm and nevertheless causes a considerable extension of the service life.
- the molybdenum is applied to the surface, for example by means of a flame spraying process, galvanically or by vapor deposition.
- FIG. 1 shows an example of a mandrel bending machine for bending pipes.
- the bend is carried out by pulling the tube 1 by means of a tensioner 2 by rotating the die 3.
- a rail 4 and a smoothing roller 5 provide the external guidance and the displaceable mandrel 6 arranged inside prevents a change in the tube diameter.
- the surfaces of the rail 4, the anti-wrinkle 5 and the dome 6 which come into contact with the tube are provided with a layer of molybdenum or molybdenum alloy.
- FIG. 2 shows an example of a wrinkle straightener 5 in which a protective layer 7 is applied to the surface 8 contacting the tube.
