The lower end of the working panel is embedded and installed on the top of the bending machine chassis and connected by electric welding. A fixing frame is welded on the top of the working panel. The present invention is provided with a pumping mechanism and a spraying mechanism, and a small pump is operated to extract the solution from the inside of the liquid storage tank, and then the solution in the liquid storage tank is transported to the upper connecting tank through the pumping pipe. When the solution on the upper connecting tank is full, the upper connecting tank will transport the solution to the flow controller through the total liquid infusion pipe in the protective pipe. The flow controller controls the transported solution so that the solution is transported to the atomizing nozzle through the liquid infusion pipe rack, and then sprays the steel bar during the spraying, thereby effectively adding a protective layer to the outer surface of the steel bar to prevent the steel bar surface from being exposed to the air for a long time and rusting.

[0004] The Chinese patent publication number CN110142352B discloses a device for bending and cutting steel bars for construction. Specifically, the device utilizes a worm gear to drive the driving shaft and turntable to rotate. The turntable drives the driving arm to bend the steel bars under the action of the bending rod and the limiting column. The rotating worm gear drives the driven shaft and the cutting knife to rotate, greatly improving the efficiency of steel bar bending and cutting. The device effectively solves the problem that existing steel bar bending machines cannot achieve cutting. The bending assembly includes a worm gear meshing with the worm gear, a turntable connected to the worm gear through a first transmission member, a bending rod fixed to the middle of the turntable, and a driving arm fixed in the radial direction of the turntable. The worm gear is rotatably connected to the support plate, and the turntable is rotatably connected to the upper part of the bracket fixed to the support plate at the lower part.
