The invention discloses galvanized flat steel mechanical bending equipment which comprises a conveyor belt support. Two U-shaped chassis are welded to the lower end of the conveyor belt support, the conveyor belt support is provided with a conveying conveyor belt which is driven by a driving motor, a rectangular baffle is fixed to the conveyor belt support and located at one end of the conveying conveyor belt, a lifting air cylinder is fixedly installed at the bottom of the inner side of a U-shaped supporting frame I, the output end of the lifting air cylinder is welded and fixed to the middleof the bottom side of galvanized round steel, an arc clamping groove is transversely formed in the middle of the upper end of the galvanized round steel, an arc magnet block is clamped and embedded into the arc clamping groove, and a U-shaped pressing plate is fixedly connected with the lower end of the output end of a pressure cylinder I. Compared with manual bending, the galvanized flat steel mechanical bending equipment is more convenient to use and saves more time and labor, the bending speed is improved, the bending efficiency is greatly improved, practicability is high, and the equipment is beneficial to popularization.
