The rebar is placed in the dotted line position in the figure. The supporting pin is fixed on the machine bed. The center pin and the bending pin are installed on the working disc. The rebar is bent when the disc rotates.

[0003] According to the description of a CNC steel bar bending machine disclosed in the patent website (authorization announcement number: CN 213436849 U), "The utility model discloses a CNC steel bar bending machine, which relates to the technical field of CNC machine tools. In the utility model, a first rotating disk and a second rotating disk are provided on the upper surface of the lifting platform, and the first rotating disk and the second rotating disk have the same structure. A rotating column is provided on the upper surface of the first rotating disk, and the rotating column and the first rotating disk are rotatably matched. A bending column is provided on the upper surface of the first rotating disk, and a first rotating shaft is provided in the first rotating disk, and a second rotating shaft is provided in the second rotating disk. An electric power box is provided on the upper surface of the device body, and an output shaft and a transmission shaft are provided in the electric power box.

The utility model solves the problem that the traditional steel bar bending machine cannot move by arranging grooves, slide grooves, latches, latch holes, limit blocks and pulleys."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can bend steel bars while increasing production efficiency by rotating the first rotating disk and the second rotating disk. The steel bar bending machine can be moved by utilizing the design of grooves, slide grooves, latches, latch holes, limit blocks and pulleys. However, in actual use, the positions of the columns used for bending steel bars on the first rotating disk and the second rotating disk are fixed.

Therefore, it is necessary to improve a CNC steel bar bending machine for water conservancy project construction to solve the above problems. Utility Model Content
