Detailed Description

The present invention will be described in further detail with reference to test examples and specific embodiments. However, it should not be understood that the scope of the above-mentioned subject matter is limited to the following embodiments, and all the technologies realized based on the present invention are within the scope of the present invention.

The technical scheme of this embodiment provides a strengthening rib shaping frock for sheet metal component, including last mould and lower mould 3, wherein, lower mould 3 is provided with a plurality of not unidimensional shaping chambeies for the shaping of not unidimensional strengthening rib, as shown in fig. 4, lower mould 3 in this embodiment includes first shaping die cavity 31 and second shaping die cavity 32, correspondingly, as shown in fig. 2 to 6, go up the mould including the first mould 1 of going up with first shaping die cavity 31 adaptation to and go up mould 2 with the second of second shaping die cavity 32 adaptation. Specifically, for example, the reinforcing ribs of the main body 81 and the connecting block 82 of the sun shade 8 are processed, the reinforcing ribs on the main body 81 can be processed by using the first upper die 1 and the first molding cavity 31, and the reinforcing ribs on the connecting block 82 can be processed by using the second upper die 2 and the second molding cavity 32.
