Sheet metal blank and method for producing a sheet metal component having a laser-welding-compliant triangular corner

摘要

A sheet metal component bent from a sheet metal blank having a triangular corner comprises a first and a second sheet metal member bent along bending lines from a base member to form two edges of the triangular corner. Two outer edges are weldable to each other to form a third edge. A recess extends into the base member, formed by a curved and/or polygonal first and second edge which protrudes towards the first edge. The second edge extends with a projection beyond a straight line defined by the bending line of the first sheet metal member. A projection tip is spaced from the first edge at least by a thickness of the sheet metal. When the sheet metal members are bent the projection is surrounded by the first edge and the recess is at least substantially closed by the projection.

1. A sheet metal component bent from a sheet metal blank having at least one triangular corner, the sheet metal component comprising:
a first and a second sheet metal member of the sheet metal blank bent along bending lines from a base member of the sheet metal blank to form two edges of the triangular corner, two outer edges of the first and second bent sheet metal members weldable to each other to form a third edge of the triangular corner, and a recess that extends into the base member in an intersection region of the two outer edges, wherein the recess is formed in the sheet metal blank by a curved and/or polygonal first edge that extends from the outer edge of the first sheet metal member into the first sheet metal member and into the base member in a concave manner, and a curved and/or polygonal second edge that extends in the second sheet metal member and in the base member and that protrudes towards the first edge, wherein the second edge extends with a projection into the recess, and wherein the projection has a projection tip spaced apart from the first edge at least by a thickness of the sheet metal; and wherein the sheet metal members are configured so that when the first and second sheet metal members are bent, the projection is surrounded by the first edge, and the recess is at least substantially closed by the projection.
