Abstract

A device for the generative production of a component, particularly a component of a gas turbine engine, includes a working chamber, a hardening means, in particular a laser, for the layerwise local hardening of an initial material disposed in the working chamber, in order to produce the component layerwise in a direction of layer construction; and a movable induction heating arrangement with a first inductor and a second inductor for induction tempering in pre-determinable regions of the working chamber, wherein the first inductor engages in the second inductor at least in one operating position and/or the first and/or second inductor is disposed on a distribution means, in particular a slider, for the layerwise disposal of initial material in the working chamber.

First claim

The invention claimed is:

1. A device for the generative production of a component of a gas turbine engine, comprising:
a frame and a platform defining at least a portion of a working chamber;
a laser for the layerwise local hardening of an initial material disposed in a portion of the working chamber, configured and arranged to produce the component layerwise in a direction of layer construction; and
a movable induction heating arrangement with a first inductor having a first electrical loop and a second inductor having a second electrical loop for induction tempering regions of the working chamber;
wherein the first electrical loop of the first inductor is nested inside the second electrical loop of the second inductor, at least in one operating position, and
wherein the second inductor is disposed on a slider, the slider being adjustably mounted on the frame, and the first inductor is disposed on a carriage, the carriage being slidably mounted on the slider; and
wherein the slider disposes layerwise initial material in the working chamber and displaces horizontally the second inductor.

2. The device according to claim 1 , wherein the first inductor is adjustable relative to the second inductor by a motor.

3. The device according to claim 1 , wherein an active surface area of the first inductor, at least in one operating position, is a distance from an active surface area of the second inductor, in the direction of layer construction or perpendicular to the direction of layer construction, the distance between the active surface area of the first inductor and the active surface area of the second inductor being less than one wall thickness (t) of the first inductor at the active surface area facing the portion of the working chamber.

4. The device according to claim 1 , wherein the first inductor has two parallel legs, which extend between two parallel legs of the second inductor.

5. A method for the generative production of a component of a gas turbine engine, comprising the steps of:
providing a frame and a platform defining at least a portion of a working chamber;
providing a laser for the layerwise local hardening of an initial material disposed in the working chamber, in order to produce the component layerwise in a direction of layer construction;
providing a movable induction heating arrangement with a first inductor having a first electrical loop and a second inductor having a second electrical loop for induction tempering regions of the working chamber; wherein the first electrical loop the first inductor is nested inside the second electrical loop of the second inductor, at least in one operating position;
layerwise local hardening of the initial material disposed, in order to produce the component layerwise in the direction of layer construction; and
induction tempering in pre-determinable regions of the working chamber by the movable induction heating arrangement,
wherein the second inductor is disposed on a slider, the slider being adjustably mounted on the frame, and the first inductor is disposed on a carriage, the carriage is slidably mounted on the slider; and
wherein the slider disposes layerwise initial material in the working chamber and displaces horizontally the second inductor.

6. A device for the generative production of a component of a gas turbine engine, comprising:
a frame and a platform defining at least a portion of a working chamber;
a laser for the layerwise local hardening of an initial material disposed in the working chamber, in order to produce the component layerwise in a direction of layer construction; and
a movable induction heating arrangement with a first inductor having a first electrical loop and a second inductor having a second electrical loop for induction tempering regions of the working chamber;
wherein the first inductor and second inductor are disposed on a slider, for the layerwise disposal of initial material in the working chamber and displacement horizontally of the second inductor, and
wherein the first inductor is disposed on a carriage, the carriage is slidably mounted on the slider.

7. The device according to claim 6 , wherein the first inductor is disposed fixed in place or adjustable on the slider.

8. The device according to claim 6 , wherein the second inductor is disposed fixed in place or adjustable on the slider.

9. The device according to claim 6 , wherein the slider has an adjustable blade, which can be lowered, for the layerwise disposal of initial material in the working chamber.

10. The device according to claim 8 , wherein
layerwise local hardening of the initial material is disposed in the working chamber, in order to produce the component layerwise in the direction of layer construction; and
induction tempering regions of the working chamber by the movable induction heating arrangement before, during and after the hardening of at least one component layer;
wherein the first inductor and second inductor are placed in different positions by the slider for tempering at least one layer of the component.
