The invention discloses a bending device for hardware processing, and particularly relates to the field of hardware processing. The bending device comprises a bottom plate, supporting legs are fixedlyarranged at the bottom of the bottom plate, a bottom cushion is fixedly arranged at the bottoms of the supporting legs, the bottom cushion is made of a rubber material, two bottom die angle adjustingdevices are arranged on the surface of the bottom plate, and the two bottom die angle adjusting devices are oppositely arranged in the center of the bottom plate; and each bottom die angle adjustingdevice comprises a sliding block, a sliding groove is formed in the surface of the bottom plate, the sliding blocks are in sliding connection with the sliding groove, the top of each sliding block isprovided with a screw rod, the outer side of each screw rod is provided with a butterfly nut, and the butterfly nut is in threaded connection with the corresponding screw rod. According to the bendingdevice for hardware processing, the bottom die angle adjusting devices are arranged, two adjusting bottom templates are in contact, so that the required angle is formed, then the bending angle can beadjusted according to needs, the adjustable amplitude is large, the adjusting speed is high, and the problem of bending resilience can be conveniently and quickly solved.
