Process for producing a deformed, locally reinforced sheet metal component and corresponding component
The process is used to produce a deformed, locally reinforced sheet-metal component ( 10 ), in which a metal reinforcing sheet ( 14 ) is secured to a metal base sheet ( 12 ) by means of a brazed join ( 16 ) before or during the deformation process, characterized in that a nickel-based brazing material is used to produce the brazed join ( 16 ).
1 . A process for producing a deformed, locally reinforced sheet-metal component ( 10 ), comprising:
subjecting the sheet-metal component to a deforming process, and
securing a metal reinforcing sheet ( 14 ) to a metal base sheet ( 12 ) by means of a brazed join ( 16 ) before or during the deformation process,
wherein a nickel-based brazing material is used to produce the brazed join ( 16 ).
2 . The process according to claim 1 , wherein the nickel-based brazing material contains about 14% of chromium, about 10.1% of phosphorous, remainder nickel.
3 . The process according to claim 2 , wherein the nickel-based brazing material additionally includes trace amounts of silicon, boron, iron and carbon.
4 . The process according to claim 1 wherein the melting point of the nickel-based brazing material is approximately 890° C., and the brazing temperature of the nickel-based brazing material is approximately 980° C.
5 . The process according to claim 1 wherein the nickel-based brazing material is applied to at least one of the metal base sheet ( 12 ) and the metal reinforcing sheet ( 14 ) in the form of a paste or by spraying or screen printing.
6 . The process according to claim 1 wherein the metal base sheet ( 12 ) and the metal reinforcing sheet ( 14 ) are produced from one steel.
7 . The process according to claim 1 wherein the metal base sheet ( 12 ) and the metal reinforcing sheet ( 14 ) are produced from different metals.
8 . The process according to claim 1 wherein at least one of the metal base sheet ( 12 ) and the metal reinforcing sheet ( 14 ) are produced from a light metal.
9 . A deformed, locally reinforced sheet-metal component ( 10 ) produced by subjecting the sheet-metal component to a deforming process, and securing a metal reinforcing sheet ( 14 ) to a metal base sheet ( 12 ) by means of a brazed join ( 16 ) produced by a nickel-based brazing material before or during the deformation process.
