Abstract
A welded component comprising two sheet metal components (51, 53) joined by at least one weld seam (55). A first sheet metal component (51) is disk-shaped and a second sheet metal component (53) is pot-shaped, and at least one of the two sheet metal components (51, 53) has a sheet thickness (s). One (51) of the two sheet metal components (51, 53) has a larger sheet thickness (S>s) in an area of the at least one weld seam (55).
Claims15
A welded component (1, 30) comprising:
- first and second sheet metal components (2, 3, 31, 32), the first and the second sheet metal components are connected to each other by at least one weld seam (4, 33),
- the first sheet metal component (32) being disk-shaped and defining an axis (a) and the second sheet metal component (31) being pot-shaped,
- at least one of the first and the second sheet metal components (2, 3) having a nominal sheet thickness (s), and
- one (11, 13, 15;
- 36, 41, 46, 51) of the first and the second sheet component being prepared, with a first tool that is closable in an axial direction and has an end face with a recess, to have surplus material in an axial direction so as to have an increased sheet thickness (S>s) in an area of the at least one weld seam (39, 40, 45, 49, 55).
A method for producing a welded component comprising first and second sheet metal components (2, 3, 31, 32) joined by at least one weld seam (4, 33), the first sheet metal component (32) is disk-shaped and the second sheet metal component (31) is pot-shaped and at least one of the first and the second sheet metal components (2, 3) has a nominal sheet thickness (s), one (11, 13, 15;
- 36, 41, 46, 51) of the first and the second sheet components has an increased sheet thickness (S>s) in an area of the at least one weld seam (39, 40, 45, 49, 55), and the method comprising the steps of:
- preparing the second, pot-shaped sheet metal component or a web (11, 13, 15) with surplus material in an axial direction;
- shearing and compressing the surplus material in the axial direction (a);
- and
- forming the increased sheet thickness (S).
A device for implementing a method for producing a welded component comprising first and second sheet metal components (2, 3, 31, 32) that are joined by at least one weld seam (4, 33), the first sheet metal component (32) being disk-shaped and the second sheet metal component (31) being pot-shaped and at least one of the first and the second sheet metal components (2, 3) having a nominal sheet thickness (s), one (11, 13, 15;
- 36, 41, 46, 51) of the first and the second sheet components having an increased sheet thickness (S>s) in an area of the at least one weld seam (39, 40, 45, 49, 55), the second, pot-shaped sheet metal component or a web (11, 13, 15) is prepared with surplus material in an axial direction;
- the increased sheet thickness (S) being formed by a first tool (18, 18a, 18b, 23, 26) that is closable in the axial direction (Z) and has a recess (20, 23b, 26b) in its end face;
- and
- the increased sheet thickness of the second sheet components is formed by compressing a part of the second sheet component with a second fixed tool (17a, 17b, 21, 22, 24, 25), which holds either the pot-shaped sheet component or the web (11, 13, 15), has an end shaped for accommodating part (12, 14, 16) of the second sheet component (11, 13, 15) that is to be compressed.
