[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a convenient steel bar bending machine for building construction, including a base plate 1 and a bending die 13. A bending mechanism is fixedly connected to the top of the base plate 1, and an adjustment mechanism is fixedly connected to the outside of the bending die 13. Two handles 25 are fixedly connected to the top of the base plate 1. The base plate 1 provides support and installation positions for other components, ensuring the stability of the entire equipment. It is the basic structure of the entire steel bar bending machine. The bending die 13 is a key component that directly acts on the steel bar for bending. The main function of the handles 25 is to facilitate the operator to carry and move the steel bar bending machine.

[0034] The bending mechanism includes a protective shell 2, the bottom of which is fixedly connected to the top of the base plate 1. A hydraulic press 3 is fixedly connected inside the protective shell 2. The protective shell 2 protects the internal hydraulic press 3 and prevents dust, debris, etc. from entering the hydraulic press 3 and affecting its normal operation. A bending block 4 is fixedly connected to the drive end of the hydraulic press 3. The hydraulic press 3 is the core component that provides power. By generating strong power, it drives the bending block 4 to move forward, thereby completing the bending operation of the steel bar on the bending die 13. The bending block 4 has a placement opening 5 inside, which is used to place the steel bar to ensure that the steel bar is placed correctly and is the starting position for the steel bar bending operation. Multiple circular grooves 6 are formed on the inner walls of the front and rear sides of the bending block 4. Springs 7 are fixedly connected to the inner walls of the opposite sides of the circular grooves 6, and ball-head columns 8 are fixedly connected to the adjacent sides of the springs 7. The outer walls of the ball-head columns 8 are slidably connected to the inner walls of the circular grooves 6. The circular grooves 6 provide installation space for the ball-head columns 8 and springs 7. When the reinforcing bar is placed into the placement opening 5, it compresses the ball-head columns 8, causing them to move into the circular grooves 6 and compress the springs 7. After the reinforcing bar is placed, the ball-head columns 8 return to their original position, limiting the reinforcing bar's movement. Multiple sets of this structure can accommodate multiple reinforcing bars simultaneously, improving processing efficiency. An installation sleeve 9 is fitted around the outside of the hydraulic press 3, and an installation assembly is fitted around the outside of the installation sleeve 9. The mounting assembly includes a mounting ring 11, the inner wall of which fits over the outer wall of a mounting sleeve 9. A support frame 10 is fixedly connected to the bottom end of the mounting sleeve 9, and the bottom end of the support frame 10 is fixedly connected to the top end of the base plate 1. The rear side of the bending die 13 is fixedly connected to the front side of the mounting ring 11. Multiple mounting bolts 12 are rotatably connected inside the mounting ring 11, with adjacent sides of the bolts 12 threadedly connected to the interior of the mounting sleeve 9. The mounting sleeve 9 is fitted over the hydraulic press 3, and the mounting ring 11 is fitted over the mounting sleeve 9, connected by the mounting bolts 12. The support frame 10 connects the mounting sleeve 9 and the base plate 1. The function of the mounting sleeve 9 and the mounting assembly is to ensure the stable installation of the bending die 13 and to allow for quick replacement of the bending die 13 via the mounting bolts 12, thus improving the flexibility of the equipment.

[0035] Reference Figure 1, Figure 2 and Figure 4 A pressure-bearing column 15 is fixedly connected to the top right side of the bending die 13. A guide opening 14 is provided at the top of the bending die 13. The outer wall of the bending block 4 is slidably connected to the inner wall of the guide opening 14. The adjustment mechanism includes a pressure-bearing column 16. The bottom of the pressure-bearing column 16 is fixedly connected to the top left side of the bending die 13. A rotating rod 17 is rotatably connected to the top of the pressure-bearing column 16. A rotating plate 18 is fixedly connected to the outside of the rotating rod 17. The pressure-bearing column 16 bears the pressure during the bending operation. On the other hand, its top end is connected to the rotating rod 17, which is an important support part of the adjustment mechanism. It provides a foundation for the rotation and adjustment of the rotating plate 18 and other components. A scale 19 is slidably connected to the inner wall of the rotating plate 18. An adjustment plate 20 is fixedly connected to the left side of the scale 19. The rotating plate 18 can rotate around the pressure-bearing column 16 through the rotating rod 17. Through the slidable connection with the scale 19, the position of the adjustment plate 20 can be adjusted, thereby adjusting the position of the tail end of the steel bar to meet different bending requirements. The adjusting plate 20 has a placement part 21 on its outer right side. The position of the adjusting plate 20 can be precisely adjusted by sliding the scale 19. The placement part 21 on the adjusting plate 20 is used to hold the end of the reinforcing bar to determine the position of the end of the reinforcing bar, so that the position of each end of the reinforcing bar is the same. At the same time, the length of the end of the reinforcing bar relative to the bending position can be adjusted. The top of the rotating plate 18 is threaded with two adjusting bolts 22. The top of the scale 19 has a groove 23. The bottom sides of the two adjusting bolts 22 are in contact with the bottom inner wall of the groove 23. The top of the bearing column 16 is fixedly connected with a sector block 24. The outer wall of the rotating plate 18 is in contact with the outer wall of the sector block 24. When the adjusting plate 20 is adjusted to the appropriate position, tightening the adjusting bolts 22 can fix the scale 19 and prevent the scale 19 from sliding during use, thereby ensuring that the adjusted position of the end of the reinforcing bar does not change and ensuring the accuracy of the reinforcing bar bending. The function of the sector block 24 is to make the outer wall of the rotating plate 18 contact the outer wall of the sector block 24 when the rotating plate 18 rotates, thereby ensuring that the placement part 21 and the bearing column 16 are on the same horizontal line, further ensuring that the tail end of each steel bar is in the same position and improving the consistency of steel bar bending.

[0036] Working principle: First, the reinforcing bar is placed in the placement opening 5 inside the bending block 4. When the reinforcing bar is placed in the placement opening 5, it will squeeze the ball head column 8. The squeezed ball head column 8 will move into the circular groove 6 and squeeze the spring 7. When the reinforcing bar is fully placed, the ball head column 8, which is no longer squeezed, will return to its original position due to the pressure generated by the compression of the spring 7. At the same time, it has a certain limiting effect on the reinforcing bar placed in the placement opening 5. By using the cooperation of multiple sets of springs 7 and ball head columns 8, multiple reinforcing bars can be placed in the placement opening 5 and bent at the same time, increasing processing efficiency. By opening the hydraulic press 3 inside the protective shell 2, power is generated to drive the bending block 4 to move forward. In conjunction with the pressure-bearing column 15 and pressure-bearing column 26 on the bending die 13, the reinforcing bar is bent. At the same time, the bending die 13 can be quickly replaced by using the installation sleeve 9 and the installation bolt 12.

[0037] The position of the adjusting plate 20 can be adjusted by sliding the scale 19 within the rotating plate 18. The placement part 21 is used to hold the tail end of the reinforcing bar. After adjusting the adjusting plate 20 to a suitable length, the scale 19 is fixed by tightening the adjusting bolt 22. Then, the rotating plate 18 is rotated to fit against the front side of the sector block 24. The sector block 24 is used to make the placement part 21 and the bearing column 16 on the same horizontal line, so that the tail end position of each reinforcing bar is the same, and the length between the tail end and the bending position can be adjusted to meet different bending requirements.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
