Flat semi-finished product made of metal and methods for producing same as well as components thereof
The invention relates, in a first aspect, to a flat semi-finished product made of metal ( 1 ), wherein said semi-finished product comprises at least out structured section ( 2 ) and at least one non-structured section, wherein said semi-finished product has non-structured edge sections ( 4 ) and exhibits a high strength. The semi-finished product made of metal ( 1 ) according to the invention is characterized in that it is designed as one piece and predetermined sections ( 2 ) are structured and predetermined sections are non-structured, wherein at least one non-structured section ( 4 ) is designed as a connecting region for positive or non-positive connection or for connecting by bonding. Furthermore, methods for producing the semi-finished products according to the invention are provided.
1. A flat semi-finished product, comprising
a metal structure having a top and a bottom, wherein said metal structure includes
at least one structured section exhibiting at least one of beaded, cup-shaped or coarse-grain stampings formed in at least one of said top and said bottom of said metal structure, wherein if more than one structured section is present then said sections are differently stamped sections where necessary,
at least one non-structured section configured as the connecting region for a substance-bonded connection, a positive connection, or a non-positive connection, and
non-structured edge sections at one or more edges of said metal structure,
wherein at least one of said at least one non-structured section and said non-structured edge sections surrounds at least one preformed notch which passes through said metal structure and extends from said top to said bottom of said metal structure, wherein said notch is not in said at least one structured section, and wherein said at least one preformed notch is formed in a depression adjacent to at least one of said non-structured section and said non-structured edge sections.
2. The flat semi-finished product as claimed in claim 1 , wherein said semi-finished product is made purely of zinc, brass, copper, aluminum, steel and high-grade steel or of a combination of these.
3. The flat semi-finished product as claimed in claim 1 , wherein said semi-finished product is manufactured in plate form or as rolled goods.
4. The flat semi-finished product as claimed in claim 1 , wherein the structured sections exhibit beaded, cup-shaped and/or coarse-grain stampings, which are stamped in different directions, both horizontally and vertically, where necessary.
5. The flat semi-finished product as claimed in claim 1 , wherein at least two structured sections exist and these exhibit at least two structured sections with different structures or stampings.
6. The flat semi-finished product as claimed in claim 1 , wherein all edge sections are non-structured.
7. The flat semi-finished product as claimed in claim 1 , wherein said flat semi-finished product is one-piece.
8. The flat semi-finished product as claimed claim 1 , wherein said flat semi-finished product is configured as a guard plate, heat-insulation or proofing plate for a vehicle.
9. A method for producing the flat semi-finished product as claimed in claim 1 , comprising the single-stage step involving the pressing or stamping of a metal sheet with predetermined structured and non-structured sections using suitable tools for the production of a flat semi-finished product made of metal.
10. The method as claimed in claim 9 , wherein the flat semi-finished product is produced by rotation stamping using counter-rotating rollers.
11. A component made from the flat semi-finished product as claimed in claim 1 or producible according to the method as claimed in claim 9 .
12. The component as claimed in claim 11 , wherein said component is configured as a guard plate, heat-insulation or proofing plate for a vehicle.
13. A guard plate, heat-insulation and/or proofing plate comprising the semi-finished product as claimed in claim 1 or the component as claimed in claim 11 .
