Sheet metal shearing type bending device and test method

The invention discloses a sheet metal shearing type bending device and a test method, the sheet metal shearing type bending device comprises a sample, a first pressure head and a second pressure head, the sample is distributed along a first direction and a second direction perpendicular to the first direction, the thickness direction of the sample is perpendicular to the first direction and the second direction, the sample is detachably mounted on the first pressure head, and the second pressure head is detachably mounted on the second pressure head. The sample comprises a fixed part connected with the first pressure head and a deformation part connected with the fixed part, the deformation part is suspended relative to the first pressure head, an interface of the fixed part and the deformation part is arranged along a second direction and a thickness direction, the first pressure head is provided with a first bending center, and the length direction of the first bending center is the same as the second direc
