Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a sheet metal bending machine die which is adjustable at multiple angles. Background Art

[0002] Sheet metal bending is the process of converting flat sheet metal into three-dimensional sheet metal through pressure equipment and special molds. Due to the different materials, thicknesses, lengths, widths of sheets and the different shapes and angles to be formed, there are bending machines with different tonnage and sizes of pressure equipment, equipped with upper and lower molds of different heights, shapes, and V-width sizes and special molds of special shapes; however, the sheet metal bending machine molds currently used cannot adjust the bending angle because the size of the mold is fixed. When materials at different angles need to be bent, different molds need to be replaced, which is time-consuming and labor-intensive, increases the labor intensity of the staff, and reduces work efficiency.
