[0020] See also Figures 1-6 In this embodiment: a steel bar straightening machine with bidirectional leveling includes a frame 1, on which two straightening frames 2 are rotatably mounted through a bearing seat, and the axes of the two straightening frames 2 are parallel. The two straightening frames 2 can work at the same time, and all machines can straighten two coils of steel bar wire rods at a time. The discharge ports of the two straightening frames 2 face opposite directions, and the two coils of steel bar wire rods can be fed from both sides of the machine respectively, so that each coil rack of steel bar wire rod has enough placement space to avoid mutual interference between the two coil racks when working, and the axis of the discharge port is parallel to the axis of the discharge port. A first pulley 3 is mounted on each of the two first pulleys 3. A first double-axle motor 4 is mounted on the frame 1. The left and right output shafts of the first double-axle motor 4 are connected to a first rotating shaft 5 via a coupling. The two first rotating shafts 5 are rotatably mounted on the frame 1 via a bearing seat. A second pulley 6 is mounted on each of the two first rotating shafts 5. The two second pulleys 6 are respectively connected to the two first pulleys 3 via a belt 7. When the first double-axle motor 4 is started, the two straightening frames (2) can be driven to rotate simultaneously through the transmission of the first rotating shaft 5 and the belt 7.

[0021] Two feeding structures 8 are installed on the frame 1. The two feeding structures 8 are respectively located at the feeding ports of the two straightening frames 2. The feeding structure 8 includes two parallel and symmetrical vertical plates 81. A driving wheel 82 is rotatably installed between the two vertical plates 81. A first sprocket 9 is installed at one end of the rotating shaft of the driving wheel 82. Vertical slide grooves are opened on the two vertical plates 81, and sliders 83 are slidably installed in the slide grooves. A driven wheel 84 is installed between the two sliders 83. A pull rod 85 is installed on the top of the two sliders 83. The top of the rod 85 passes through the top of the slide groove of the vertical plate 81, and a connecting rod 87 is installed between the top ends of the two pull rods 85. A spring 86 is sleeved on the two pull rods 85. The spring 86 always rests between the slider 83 and the top of the slide groove of the vertical plate 81. Under normal circumstances, the driving wheel 82 is in contact with the driven wheel 84. Pulling the connecting rod 87 upwards can separate the driving wheel 82 and the driven wheel 84. After loosening the connecting rod 87, the driven wheel 84 can be reset by the spring 86. The driving wheel 82 and the driven wheel 84 cooperate to clamp the steel bars.

[0022] The frame 1 is provided with a second double-axle motor 10 and two reduction gearboxes 11. The two reduction gearboxes 11 are respectively located on the left and right sides of the second double-axle motor 10, and the input ends of the two reduction gearboxes 11 are respectively connected to the left and right output shafts of the second double-axle motor 10. The output ends of the two reduction gearboxes 11 are connected to the second rotating shaft 12 through a coupling. The two second rotating shafts 12 are both rotatably mounted on the frame 1 through a bearing seat. The frame 1 is also rotatably provided with two third rotating shafts 13 through a bearing seat.

The top of the frame 1 is covered with a protective cover 18, and the two straightening frames 2 are both located below the protective cover 18.

[0024] The working principle and usage process of the present invention are as follows: When the steel bar straightening machine with bidirectional leveling is used, the steel bar is first passed through the driving wheel 82 and the driven wheel 84 of the feeding structure 8, then through the inlet and outlet of the straightening frame 2, and finally through the entrance of the cutting machine 17. The rollers on the straightening frame 2 are adjusted so that the rollers contact the steel bar, and then the protective cover 18 is covered. The first double-axis extension motor 4, the second double-axis extension motor 10 and the cutting machine 17 are started. The first double-axis extension motor 4 drives the two straightening frames 2 to rotate simultaneously to straighten the steel bar. The second double-axis extension motor 10 drives the driving wheels 82 of the two feeding structures 8 to rotate simultaneously. The steel bar is transported by the cooperation of the driving wheel 82 and the driven wheel 84. The cutting machine 17 works once at intervals to cut the straightened steel bar.
