[0003] However, traditional steel bending machines often face some technical challenges in their design and use, especially for thin and hard materials such as steel bars. One of the most prominent problems is the design of the fixing structure. Traditional fixing structures generally adopt the form of through grooves. Although this design facilitates the placement and positioning of steel bars, it exposes obvious disadvantages in actual operation.
[0004] During the steel bending process, especially when the steel bar is bent significantly, due to the hardness and elasticity of the material itself, a huge force will be generated during the bending process. This force not only acts on the bending mechanism itself, but also generates a huge friction force on the contact point between the steel bar and the fixed structure. When this friction force exceeds the friction force between the fastener and the steel bar, the steel bar may deviate from the through slot, resulting in deviations in the bending angle and shape, which in turn affects the quality and safety of the entire project.

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example 1
[0027] Please refer to the attached Figure 1-6 The present embodiment is a steel bender for construction: it includes a fixed plate 1, a first bracket 2 is fixedly connected to the fixed plate 1, a carrier plate 3 is installed on the first bracket 2, the carrier plate 3 is fixedly connected to a cushion block 4, a bending rod 5 is rotatably connected to the cushion block 4, a placement hole 6 is provided on the carrier plate 3, the placement hole 6 is located between the bending rod 5 and the cushion block 4, a fixer 7 is provided below the placement hole 6, the fixer 7 is fixedly connected to a second bracket 8, and the second bracket 8 is installed on the first bracket 2.
[0028] The fixing plate 1 is fixed to the ground or the base by expansion screws to ensure stable and firm support for the first bracket 2. The first bracket 2 is an inverted L-shaped structure, and the carrier plate 3 is located on the upper side of the first bracket 2. The first bracket 2 can raise the height of the carrier plate 3, reduce the number of times the user bends during bending work, reduce the difficulty of work during the work process, and facilitate the user to perform bending operations. The pad 4 and the bending rod 5 are located on the upper side of the carrier plate 3, and the storage hole 6 is located between the pad 4 and the bending rod 5. The steel bar for bending is vertically placed in the storage hole 6, and the fixer 7 on the lower side of the storage hole 6 fixes one end of the steel bar. After the steel bar is fixed, it is pressed toward one side of the pad 4 by pressing the bending rod 5, thereby completing the bending of the steel bar. The storage hole 6 and the fixing block fix the steel bar during the pressing process to avoid deviation of the steel bar during the pressing process and ensure the bending angle and shape.
[0029] The bending rod 5 includes a connecting block 501, which is rotatably connected to the cushion block 4. A pressure rod 502 is fixedly connected to the outer side of the connecting block 501, and a pressure block 503 is provided on the inner side of the connecting block 501. A first adjusting screw 504 is rotatably connected to the pressure block 503, and the first adjusting screw 504 is threadedly connected to the connecting block 501.
[0030] One end of the connecting block 501 of the bending rod 5 is rotatably connected to the cushion block 4, and the pressing block 503 is located on the inner side of the connecting block 501. The area between the pressing block 503 and the cushion block 4 is a placement area for the steel bars. The pressing block 503 is a straight structure, and the pressing block 503 is tangent to the outer contour of the cushion block 4. The gap between the pressing block 503 and the cushion block 4 can be adjusted by the first adjusting screw 504, so that the pressing block 503 maintains a fit with the steel bars in the initial position, reducing the angular error of the bending during bending. The pressing rod 502 can extend the force arm of the pressing block 503, and utilizes the principle of leverage to facilitate the user to perform the pressing and bending work.
[0031] Furthermore, in order to better position the steel bars and avoid separation during the pressing process, a pressing groove 9 is provided on the pad 4, and the bent steel bars just enter the pressing groove 9. The pressing groove 9 can also limit the forward position of the steel bars to ensure that the bent shape will not deviate.
[0032] When the display window 11 on the connecting block 501 is initially positioned, it faces the zero degree line of the scale line 10 on the pad 4, and the pressing block 503 is in a vertical position. When the pressing rod 502 drives the connecting block 501 and the pressing block 503 to rotate, the display window 11 rotates synchronously with the connecting block 501. The degree of the scale line 10 displayed on the display window 11 indicates the angle at which the bender bends the steel bar, which is convenient for controlling the bending angle of the steel bar.
[0033] The carrier plate 3 is rotatably connected to the first bracket 2. A shaft sleeve 12 is provided at the bottom of the carrier plate 3, and a worm gear 13 is installed on the shaft sleeve 12. When the worm 14 is rotated, the worm gear 13 can be driven to rotate. The rotation of the worm gear 13 drives the shaft sleeve 12 to rotate. The rotation of the shaft sleeve 12 can drive the rotation of the carrier plate 3. The rotation of the carrier plate 3 drives the upper bending rod 5 and the cushion block 4 to rotate, thereby changing the force direction of the bending rod 5, and placing the bending rod 5 at an angle suitable for force application to meet the use needs of different users. In order to further improve the firmness of the fixation between the carrier plate 3 and the first bracket 2, under the premise of reverse self-locking of the worm gear 13 and worm 14, a limit pin 17 is added. The limit pin 17 is inserted into the limit hole 15 and the slot 16. There are two limit holes 15, and the two limit holes 15 are distributed on the carrier plate 3 at 180 degrees, and the slots 16 are distributed circumferentially on the first support rod.
[0034] There are two pulleys 702 in the holder 7, and sliders 703 are provided at both ends of the two pulleys 702. There is only sliding freedom between the sliders 703 and the fixing seat 701. There are two different thread grooves on the second adjusting screw 704. The sliders 703 on the same side of the two pulleys 702 are located on the two different thread grooves of the second adjusting screw 704. When the second adjusting screw 704 is rotated, the two sliders 703 are relatively close to or away from each other, so that the gap between the two pulleys 702 is adjusted. Furthermore, in order to facilitate the rotation and adjustment of the second adjusting screw 704, second adjusting screws 704 are installed on the sliders 703 on the left and right sides. The two second adjusting The threads on the section screw 704 have opposite rotation directions, and the two second adjusting screws 704 are connected to the first gear 705. The two first gears 705 are driven by the second gear 706, and the second gear 706 drives the two second adjusting screws 704 to rotate synchronously in opposite directions through the first gear 705. Therefore, the opposite rotation directions of the threads on the two second adjusting screws 704 can ensure the synchronous and stable sliding of the two sliders 703 on both sides, so that the slider 703 can have a better supporting effect on the pulley 702. The pulley 702 is selected to be fixed in the fixture 7 when installing or removing the steel bars. The steel bars and the fixture 7 have rolling friction in the vertical direction, which is convenient for the extraction and insertion of the steel bars. Example 2
[0035] The structure is the same as the above embodiment. Figure 7 As shown, the specific difference of this embodiment is: "A sliding sleeve 18 is fixedly connected to the second bracket 8, the sliding sleeve 18 is slidably connected to the first bracket 2, and the sliding sleeve 18 is fixedly connected to the first bracket 2 by fixing bolts."
[0036] Since the bending lengths of the steel bars used in different scenarios are different, the second bracket 8 can be adjusted in vertical height under the action of the sliding sleeve 18, so that the fixer 7 can better fix one end of the steel bar, avoid unnecessary bending of the steel bar, ensure the angle and shape of the finished product after the steel is bent, and improve the applicability of the device.
[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.
