After adjustment, the upper positioning bolt 12 is rotated and repositioned on the upper surface of the mounting plate 8, thereby realizing the positioning of the movable pin 10 after moving in the through groove 9, that is, realizing the positioning of the second roller body 11 after the position adjustment relative to the first roller body 6.

The working principle of a steel bar bending machine in this embodiment is as follows:

Insert multiple steel bars from left to right between the positioning plate 4 and the positioning platform 2, and place the steel bars under the limiting plate 27. Drive the positioning plate 4 to move forward to approach the side walls of the multiple steel bars by opening the cylinder 3, until the positioning plate 4 and the positioning platform 2 respectively fit the side walls of the steel bars, so as to achieve the clamping and positioning of the multiple steel bars between the positioning plate 4 and the positioning platform 2; drive the lead screw 24 to rotate by turning the hand wheel 25, so as to promote the connection frame 26 to move downward along the limiting groove 23, until the limiting plate 27 fits tightly against the upper surface of the steel bars, so as to achieve the limiting of the upper part of the multiple steel bars arranged vertically;

The first rotating rod 18 and the first gear 19 are driven to rotate by the turned-on motor 17, thereby driving the second gear 21, the second rotating rod 20, and the driving arm 22 to rotate synchronously. At this time, the driving pin 15 at the driving arm 22 drives the third roller 14 to rotate synchronously along the slide groove 13, causing the left end of the steel bar to bend backward, thereby realizing the synchronous bending processing of multiple steel bars;

When the diameter of the steel bar changes and the spacing between the second roller body 11 and the first roller body 6 needs to be adjusted, the upper positioning bolt 12 is rotated to disengage from the movable pin 10, and the movable pin 10 is driven by an external force to move along the through slot 9 to a suitable position, so as to adjust the position of the second roller body 11 at the bottom of the movable pin 10. After the adjustment, the upper positioning bolt 12 is rotated and repositioned on the upper surface of the mounting plate 8, thereby realizing the positioning of the movable pin 10 after moving in the through slot 9, that is, realizing the positioning of the second roller body 11 after the position adjustment relative to the first roller body 6;

The utility model can realize the synchronous bending processing of multiple steel bars at one time, which is more efficient than the traditional method of bending one steel bar at a time, and is more conducive to the continuous and efficient production of the bending processing of batch steel bars. When multiple steel bars are stacked, they are stabilized under the limiting action of the positioning plate 4 and the limiting piece 27. When all the steel bars stacked up and down are bent subsequently, the steel bars will not be out of the limit position, thereby ensuring the normal progress of the bending process.
