The utility model discloses an explosion-proof bending device which is arranged on a base. Comprising a bending mechanism and an edge cutting mechanism. The bending mechanism comprises a positioning block and a forming assembly. The forming assembly is arranged on the support, and the support is fixed to the upper surface of the base. The forming assembly comprises a driving piece, the tail end of the driving piece penetrates through the support, and a sliding block and a pressing plate are fixed to the tail end of the driving piece. A forming upper die is arranged on the inner side of the sliding block, and the pressing plate is located on the outer side of the forming upper die. The trimming mechanism comprises a trimming die, and a cutter equivalent to the outline of the inner wall of the fillet sheet metal part is formed on the trimming die; a wedge-shaped groove matched with the bottom end of the sliding block is formed in the trimming die. The sheet metal part bending device has the advantages that the edges of the sheet metal part are bent on the basis of a common bending machine, the corners of the sheet metal part are warped and not broken, then the corners of the sheet metal part with the edges bent are bent, the sheet metal part is integrated and does not need to be fixed in a welded mode, the sealing performance and the overall structure are stable, and the sheet metal part bending device is convenient to use. And the explosion-proof effect can be achieved.
