The movable plate 15 moves forward. When the movable plate 15 moves to contact the hinge joint steel bar, the magnet sheet 16 absorbs the steel bar. At this time, as the hydraulic inner rod 10 continues to exert force, the slider 17 is pushed forward in the slide groove 11. The hydraulic inner rod 10 transmits the force to the movable plate 15 through the support plate 20 to press the steel bar forward. At the same time, as the angle of the steel bar changes, the movable plate 15 and the steel bar are always in contact under the action of the first rotating rod 14, which is convenient for the steel bar to be effectively pressed straight, avoiding artificial straightening, saving time and effort, and a second pump box 4 is fixedly installed on one side of the surface of the fixed plate 2. , an air suction pump 5 is fixedly installed inside the second pump box 4, and the model is KB-140V.

[0028] The third step: start the hydraulic pump 8 to drive the hydraulic sleeve to move forward, thereby causing the push plate 12 to move forward, driving the movable plate 15 to move forward. When the movable plate 15 moves to contact the hinged joint steel bars, the magnet sheet 16 absorbs the steel bars.
