Abstract

The present invention relates to an apparatus for tempering hot articles, in particular an apparatus for homogeneous, contactless tempering of primarily non-endless surfaces that are to be tempered; the tempering apparatus has at least one tempering blade or a tempering cylinder; the tempering blade or tempering cylinder is embodied as hollow and has a tempering blade nozzle edge or a plurality of tempering cylinders arranged in a row; in the nozzle edge at least one nozzle is provided, which is aimed at an article to be tempered; and at least seven tempering blades are arranged in such a way that the flow pattern on the surface to be tempered forms a honeycomb-like structure; and to a method therefor.

First claim

The invention claimed is:

1. A tempering apparatus for tempering articles that are to be tempered, the tempering apparatus comprising:
a tempering blade frame ( 8 );
at least seven tempering blades ( 2 ) disposed in the tempering blade frame ( 8 ); and
a fluid supply box ( 15 ) in operable communication with the at least seven tempering blades ( 2 ),
wherein each tempering blade ( 2 ) is hollow and has a tempering blade nozzle edge ( 6 ) comprising at least one nozzle ( 10 ) configured to be aimed at an article to be tempered,
wherein the at least seven tempering blades are arranged in such a way that a honeycomb-shaped flow pattern is formed on a surface of the article to be tempered,
wherein a moving device ( 16 ) is provided, with which the at least seven tempering blades ( 2 ) can be moved with the tempering blade frame ( 8 ) and the fluid supply box ( 15 ), with which the article to be tempered can be moved relative to the at least seven tempering blades ( 2 ) so that a swinging or oscillating movement relative to each other can be produced, and
wherein the tempering apparatus is equipped with units such that the tempering blade frame ( 8 ) with the at least seven tempering blades ( 2 ) disposed therein is configured to swing or oscillate around all three of the X axis, the Y axis, and the Z axis simultaneously.

2. The tempering apparatus according to claim 1 , wherein the at least seven tempering blades ( 2 ) are arranged parallel to and spaced apart from one another.

3. The tempering apparatus according to claim 1 , wherein the at least seven tempering blades ( 2 ) are respectively offset from one another by half a distance between the nozzles ( 10 ) at the nozzle edge ( 6 ).

4. The tempering apparatus according to claim 1 , wherein each tempering blade ( 2 ) further comprises a tempering blade base ( 3 ), tempering blade broad sides ( 4 ), and tempering blade narrow sides ( 5 ),
wherein in each tempering blade ( 2 ), the nozzle edge ( 6 ), the tempering blade broad sides ( 4 ), and the tempering blade narrow sides ( 5 ) border a cavity ( 7 ),
wherein the tempering blade base ( 3 ) of each tempering blade ( 2 ) is disposed in or on the tempering blade frame ( 8 ), and
wherein the tempering blade frame ( 8 ) is disposed on the fluid box ( 15 ).

5. The tempering apparatus according to claim 1 , wherein the following conditions are present:
hydraulic diameter of nozzle=DH, where DH=4×A/U
distance of nozzle from article=H
distance between two tempering blades=S
length of nozzle=L
L>=6×DH
H<=6×DH, esp. 4 to 6×DH
S<=6×DH, esp. 4 to 6×DH
oscillation=half of the spacing distance between two tempering blades in X axis direction and Y axis direction.

6. The tempering apparatus according to claim 1 , wherein the tempering blade frame ( 8 ) with the at least seven tempering blades ( 2 ) disposed therein is configured to swing or oscillate around all three of the X axis, the Y axis, and the Z axis simultaneously at an oscillation speed of 0.25 seconds per cycle.

7. A method for tempering articles that are to be tempered, the method comprising:
providing the tempering apparatus according to claim 1 , the at least seven tempering blades ( 2 ) being arranged parallel to and spaced apart from one another;
providing an article with a hot surface to be tempered;
moving the tempering apparatus and the article with the hot surface relative to each other;
aiming the nozzles ( 10 ) of the at least seven tempering blades ( 2 ) at the article with the hot surface to be tempered; and
directing, by the nozzles ( 10 ), a tempering fluid at the hot surface of the article to be tempered such that after contacting the hot surface, the tempering fluid flows away in spaces between the tempering blades ( 2 ),
wherein during the directing of the tempering fluid at the hot surface of the article to be tempered, the tempering blade frame ( 8 ) with the at least seven tempering blades ( 2 ) disposed therein swings or oscillates around all three of the X axis, the Y axis, and the Z axis simultaneously.

8. The tempering apparatus according to claim 1 , wherein the tempering apparatus is equipped with units such that the tempering blade frame ( 8 ) with the at least seven tempering blades ( 2 ) disposed therein is configured to swing and oscillate around the all three of the X axis, the Y axis, and the Z axis simultaneously.

9. The method according to claim 7 , wherein during the directing of the tempering fluid at the hot surface of the article to be tempered, the tempering blade frame ( 8 ) with the at least seven tempering blades ( 2 ) disposed therein swings and oscillates around all three of the X axis, the Y axis, and the Z axis simultaneously.
