Device for producing, repairing and/or replacing a component by means of a powder that can be solidified by energy radiation, method and component produced according to said method
The invention relates to a device for producing, repairing and/or replacing a component, particularly an aircraft component, by means of a powder that can be solidified by energy radiation of an energy radiation source, characterized in that the device comprises an application unit that is designed such that the powder can be applied onto an uneven surface by means of the application unit.
1. A device which is suitable for producing and/or repairing a component by means of a powder that is capable of being solidified by energy radiation from an energy radiation source, wherein the device comprises an application unit which is configured so that it is capable of applying powder to be solidified onto a curved or arcuate surface in the form of at least one curved or arcuate powder layer which can subsequently be solidified by the energy radiation from the energy radiation source.
2. The device of claim 1 , wherein the application unit is configured so that it is moveable on a path along a contour or a contour profile of the curved or arcuate surface.
3. The device of claim 1 , wherein the application unit is present as a cylindrical blade.
4. The device of claim 1 , wherein the application unit is present as a cylindrical roll.
5. The device of claim 1 , wherein the application unit is present as a scraper with a straight or planar shape.
6. The device of claim 1 , wherein the application unit is present as a curved scraper or a curved blade.
7. The device of claim 1 , wherein a shape of the application unit is adapted to a contour or a contour profile of the curved or arcuate surface to apply a powder layer onto the curved or arcuate surface.
8. The device of claim 1 , wherein the application unit is configured so as to be replaceable.
9. The device of claim 1 , wherein the application unit is connected to a drive unit for moving the application unit.
10. The device of claim 9 , wherein the drive unit is connected to a control unit, the control unit controlling the drive unit and the application unit connected thereto as a function of a predetermined path profile.
11. The device of claim 10 , wherein the control unit comprises an NC controller.
12. The device of claim 9 , wherein the application unit is movable by the drive unit in two directions in space.
13. The device of claim 9 , wherein the application unit is movable by the drive unit in all three directions in space.
14. The device of claim 1 , wherein the device further comprises a support platform, the support platform having a curved or arcuate surface which is adapted to a curved or arcuate contour or outer contour of a component.
15. The device of claim 1 , wherein the device further comprises an energy radiation source which is positioned so as to be capable of solidifying the at least one curved or arcuate powder layer present on the curved or arcuate surface.
16. The device of claim 15 , wherein the energy radiation source comprises a laser beam.
17. The device of claim 15 , wherein the energy radiation source comprises an electron beam.
18. The device of claim 1 , wherein the curved or arcuate surface is a concave surface.
19. The device of claim 1 , wherein the curved or arcuate surface is a convex surface.
20. A device which is suitable for producing and/or repairing a component by means of a powder that is capable of being solidified by energy radiation from an energy radiation source, wherein the device comprises an application unit which is configured so that it is capable of applying powder to be solidified onto a non-moving curved or arcuate surface in the form of at least one curved or arcuate powder layer which can subsequently be solidified by the energy radiation from an energy radiation source, and wherein the application unit is configured so that it is moveable on a path along a contour or a contour profile of the curved or arcuate surface and is movable in one, two or three directions in space by being connected to a drive unit.
