[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-3 A steel bar straightening device shown includes a body 1 and a fixing plate a7 mounted on the outer wall of the upper end of the body 1;

[0024] The front end outer wall of the fixed plate a7 is connected to the lower driving roller group a4 near the lower side to drive the steel bars to move;

[0025] A plurality of upper clamping roller groups a6 are provided on the upper side of the lower driving roller group a4 to clamp the steel bars according to different thicknesses;

[0026] A fixing plate b11 is arranged on the right side of the fixing plate a7, and the front end outer wall of the fixing plate b11 is connected to the lower driving roller group b15 for driving the steel bar to move, and an upper clamping roller group b13 is arranged on the upper side of the lower driving roller group b15. When the bent steel bar is straightened, the steel bar is first inserted from the left side between the lower driving roller group a4 and the upper clamping roller group a6, and the lower driving roller group a4 drives the bent steel bar to move from left to right, and under the clamping restriction of the upper clamping roller group a6, the bent surface of the steel bar is straightened, and then the bent steel bar is discharged after being straightened for a second time between the lower driving roller group b15 and the upper clamping roller group a6.

[0027] A fixing sleeve 5 is fixedly connected to the leftmost part of the center of the front end outer wall of the fixing plate a7 to limit the entry direction of the bent steel bar. Clamping rollers 17 are arranged inside the fixing sleeve 5 and close to the upper and lower sides to limit the moving space of the steel bar. When the bent steel bar is moved between the lower driving roller group a4 and the upper clamping roller group a6, the steel bar is inserted from the inside of the fixing sleeve 5, and its position will be restricted by the two clamping rollers 17 during the movement of the bent steel bar to avoid the bent steel bar from shaking up and down when moving.

[0028] like Figure 2 and Figure 3 As shown, the inner walls of the left and right ends of the fixed sleeve 5 and the two sides close to the upper side are fixedly connected with positioning rods 18 that pass through the inside of the clamping roller 17 to limit the position of the clamping roller 17, the circular outer walls of the two clamping rollers 17 and the two sides close to the left and right sides are fixedly connected with limiting plates 19 to limit the position of the clamping roller 17, the circular outer walls of the two clamping rollers 17 and the limiting rings 20 located on the left and right sides are fixedly connected to limit the moving space of the steel bar, and a connecting block 16 is fixedly connected between the rear end outer wall of the fixed sleeve 5 and the fixed plate a7.

[0029] When the bent steel bar moves inside the fixed sleeve 5, the clamping roller 17 will move on the positioning rod 18 to assist the movement of the steel bar, and the limit plate 19 can limit the movement space of the clamping roller 17 to avoid the situation of driving the steel bar to move. At the same time, the limit ring 20 can limit the movement range of the steel bar to reduce the shaking space of the steel bar.

[0030] like Figure 3 As shown, the two clamping rollers 17 can rotate clockwise or counterclockwise on the positioning rod 18, and the two clamping rollers 17 are made of stainless steel.

[0031] The rotation of the clamping roller 17 in different directions can assist in driving the steel bar to move from left to right or from right to left.

[0032] like Figure 1 As shown, threaded holes 10 are provided inside the upper outer walls of the fixed plates a7 and b11, and movable plates 12 are provided on the rear end outer walls of the upper clamping roller group a6 and the upper clamping roller group b13. The internal threads of the threaded holes 10 are connected to threaded rods 8 that penetrate downwardly into the movable plate 12, and the upper outer wall of the threaded rods 8 is fixedly connected to an adjusting handle 9 to control the up and down movement of the movable plate 12.

[0033] When adjusting the position of the upper clamping roller group a6 and the upper clamping roller group b13, the movable plate 12 can be driven upward by rotating the adjustment handle 9 counterclockwise to drive the upper clamping roller group a6 and the upper clamping roller group b13 to move upward, while when rotating clockwise, the upper clamping roller group a6 and the upper clamping roller group b13 are driven downward to clamp the steel bars.

[0034] like Figure 1 As shown, the front end outer wall of the fuselage 1 is internally transmission-connected with a plurality of cabinet doors 2, the four corners of the lower end outer wall of the fuselage 1 are fixedly connected with supporting feet 3, the rear end outer walls of the fixed plates a7 and b11 are fixedly connected with transmission track boxes 14 to cover the transmission tracks, and a driving motor is arranged inside the fuselage 1.

[0035] When the lower driving roller group a4 and the lower driving roller group b15 drive the steel bars to move, the driving motor inside the body 1 drives the transmission track box 14 to rotate, and drives the transmission shaft on the rear side of the lower driving roller group a4 and the lower driving roller group b15 to rotate, so that the lower driving roller group a4 and the lower driving roller group b15 can be controlled to rotate and drive the steel bars to move.

[0036] The implementation principle of this embodiment is as follows: when the bent steel bar is straightened, the steel bar is first inserted from the left side between the lower driving roller group a4 and the upper clamping roller group a6. The lower driving roller group a4 will drive the bent steel bar to move from left to right, and under the clamping limit of the upper clamping roller group a6, the bent surface of the steel bar is straightened, and then the bent steel bar is straightened for a second time between the lower driving roller group b15 and the upper clamping roller group a6 before being discharged. When the bent steel bar is moved between the lower driving roller group a4 and the upper clamping roller group a6, the steel bar is inserted from the inside of the fixed sleeve 5, and its position will be restricted by the two clamping rollers 17 during the movement of the bent steel bar to prevent the bent steel bar from shaking up and down when moving.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
