[0002] Steel bars are the most commonly used building material in construction projects, especially in today's buildings. In order to improve the seismic performance of buildings, most buildings adopt frame structures during construction. Steel bars are one of the indispensable materials when building building frames. Usually in the specific construction process, workers often use steel bar cutting equipment to cut steel bars according to construction requirements.

At this time, the two vertical plates of the moving block 4 threaded on the outer surface of the threaded rod 11 continue to move upward through the threads set on the outer surface of the threaded rod 11. At this time, the active roller 7 set in the moving block 4 moves upward. The rotation directions of the threads of the two threaded rods 11 in the utility model are opposite.

At this time, the two vertical plates of the moving block 4 threaded on the outer surface of the threaded rod 11 continue to move upward through the threads set on the outer surface of the threaded rod 11. At this time, the active roller 7 set in the moving block 4 moves upward. The rotation directions of the threads of the two threaded rods 11 in the utility model are opposite. Even if the two second bevel gears 10 rotate in opposite directions, the moving block can still be kept moving in the same direction of the two threaded rods 11. In this way, the active roller 7 and the auxiliary roller 5 can be adjusted according to the diameter of the steel bar. The distance between them is determined. At this time, the steel bar is placed between the active roller 7 and the auxiliary roller 5. At this time, by starting the motor 6, the motor 6 drives the active roller 7 fixedly mounted on the outer surface of the output shaft to rotate, and the steel bar is transported by rotation, and the steel bar is transported to the groove 13 opened on the upper surface of the cutting table 12.

At this time, the plywood 16 clamps and fixes the steel bar. At this time, by starting the hydraulic press 18, the hydraulic press 18 drives the hydraulic rod 19 slidingly mounted on the inner surface to move downward through operation. The hydraulic rod 19 applies a downward thrust to the movable plate 20 fixedly mounted at the lower end.
