Abstract

A lamella block is provided for a calibrating device for calibrating an extruded profile. The lamella block includes a lamella structure, which has a plurality of lamellae that are spaced apart from each other by grooves and arranged in the longitudinal direction of the lamella block. The lamella structure has two lamella sets, wherein the lamellae of the first lamella set are arranged offset in relation to the lamellae of the second lamella set in the longitudinal direction of the lamella block. Further provided is a method for manufacturing the lamella block mentioned above as well as a calibrating device, which includes a plurality of the lamella blocks mentioned above. Also provided is a system for additively manufacturing the lamella block mentioned above, a corresponding computer program and a corresponding dataset.

First claim

What is claimed is:

1. A lamella block for a calibrating device for calibrating an extruded profile, wherein the lamella block comprises:
a carrier structure having opposite first and second walls extending along a longitudinal direction of the lamella block, said first and second walls residing on first and second imaginary planes, respectively; and
a lamella structure having a plurality of lamellae all extending outwards from the carrier structure and being spaced apart from each other in the longitudinal direction by grooves, wherein the plurality of lamellae comprises first and second lamella sets, wherein lamellae of the first lamella set are arranged offset relative to lamellae of the second lamella set in the longitudinal direction of the lamella block,
wherein each lamellae of the first lamella set extends beyond the first imaginary plane in a direction normal thereto, and does not extend beyond the second imaginary plane in a direction normal thereto, and
wherein each lamellae of the second lamella set extends beyond the second imaginary plane in said direction normal thereto, and does not extend beyond the first imaginary plane in said direction normal thereto.

2. The lamella block according to claim 1 , wherein the lamellae of the first lamella set and the lamellae of the second lamella set have the same shape in mirror-image.

3. The lamella block according to claim 1 , wherein the first and second lamella sets have an identical or differing division.

4. The lamella block according to claim 1 , wherein the lamellae of the first lamella set are arranged offset in relation to the lamellae of the second lamella set in such a way that the lamellae of the first lamella set coincide with the grooves of the second lamella set in the longitudinal direction of the lamella block.

5. The lamella block according to claim 1 , wherein the carrier structure and the plurality of lamellae are fabricated out of the same material or out of different materials.

6. The lamella block according to claim 1 , wherein the lamella block is integrally designed.

7. The lamella block according to claim 1 , wherein the lamella block is manufactured by means of 3D printing or by means of an additive manufacturing process.

8. A calibrating device for calibrating extruded profiles, comprising a plurality of lamella blocks according to claim 1 , wherein the lamella blocks are arranged relative to each other to form a calibrating opening.

9. The calibrating device according to claim 8 , wherein the calibrating device comprises a plurality of activating devices, wherein each activating device is coupled with a respective lamella block so as to individually activate each lamella block.

10. A method for manufacturing a lamella block according to claim 1 , comprising the step of manufacturing the lamella block by means of 3D printing or by means of additive manufacturing.

11. The method according to claim 10 , further comprising the step of calculating a lamella block geometry and converting the calculated 3D geometric data into corresponding control commands for 3D printing or additive manufacturing.

12. A method for manufacturing a lamella block, comprising the following steps:
generating a dataset, which images the lamella block according to claim 1 ;
storing the dataset on a storage device or a server; and
inputting the dataset into a processing device or a computer, which actuates an additive manufacturing device so that the latter fabricates the lamella block imaged in the dataset.

13. A computer program, comprising datasets, which while the datasets are being read in by a processing device or a computer, prompts the processing device or the computer to actuate an additive manufacturing device in such a way that the additive manufacturing device fabricates the lamella block with the features according to claim 1 .

14. A computer-readable data carrier, which stores the computer program according to claim 13 .

15. A dataset, which images the lamella block with the features according to claim 1 .

16. The lamella block according to claim 1 , wherein the first and second imaginary planes are parallel with respect to one another.
