[0029] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0030] Refer to the attached Figure 1-4 As shown, the steel bar hoop bending machine in this embodiment includes a working frame 1. The working frame 1 is the main body of the device and plays a role of fixed support. At the same time, the working frame 1 forms an assembly chamber to facilitate the subsequent assembly of various other mechanisms. Then, a transmission mechanism, a cleaning mechanism, a hydraulic clamp 8 and a hoop bending mechanism are sequentially arranged on the outside of the assembly chamber (i.e., the front side). In this embodiment, in order to facilitate the collection of the bent hoops after shearing, a collection box 11 is provided below the hydraulic clamp 8 and the hoop bending mechanism near the hydraulic clamp 8.

[0031] In this embodiment, specifically, the transmission mechanism forms at least two clamping cavities on the outside of the work frame 1, and then the steel bars move along the clamping cavities to form a transmission track, which is convenient for conveying and transmitting the steel bars to be processed. At this time, the cleaning mechanism is set at the end of the transmission, so that it can clean first and then perform other processing. At this time, the two cleaning components move to form a cleaning space of variable size, which is more applicable.

[0032] First, the specific cleaning mechanism in this embodiment is introduced as follows:

[0033] Reference Figure 1 and Figure 4 As shown, in this embodiment, two cleaning assemblies are formed on the front side of the work frame 1, and the two cleaning assemblies are symmetrically arranged facing each other, so that the two iron brushes 17 in the cleaning assemblies form a working state of being close to or far away from each other.

[0034] Refer to the attached Figure 1 and 4As shown, the cleaning assembly includes a fixed block 12 fixedly connected to the working frame 1. The fixed block 12 is used to limit the limiting rod 13. At this time, at the bottom of the fixed block 12, two limiting rods 13 are slidably connected in a direction perpendicular to the working frame 1. After the limiting rod 13 passes through the through hole on the fixed block 12, it can move in the vertical direction along the fixed block 12 under the action of external force.

[0035] In this embodiment, the two fixed blocks 12 in the two cleaning assemblies are fixedly connected to a sleeve 14 on one side thereof that is close to each other. The sleeve 14 and the cylindrical sleeve 16 on the iron brush 17 are used to prevent the spring 15 from deforming. The spring 15 located between the two limit rods compresses the spring when the iron brush 17 is in contact with the steel bar. After the steel bar passes through, the spring is reset when no force is applied, thereby helping to push the iron brush 17 so that the two iron brushes 17 fit together. Specifically, one side of the spring 15 is fixedly connected to the inside of the sleeve 14, and the other side of the spring 15 is fixedly connected to the inside of the cylindrical sleeve 16. The inner side of the sleeve 14 is slidably connected to the cylindrical sleeve 16. At this time, the diameter of the sleeve 14 is larger than the outer diameter of the cylindrical sleeve 16, and the sleeve 14 covers the outer side of the cylindrical sleeve 16.

[0036] Secondly, the bending hoop mechanism is introduced as follows:

[0037] Refer to the attached Figure 1 and 3 It can be seen that the outside of the work frame 1 is fixedly connected to a motor 2, and the motor 2 is used to generate power to drive the rotating rod 3 to rotate. The front side of the motor 2 is fixedly connected to the rear side of the work frame 1, and the driving end of the motor 2 is fixedly connected to the rotating rod 3. The rotating rod 3 is used to connect with the turntable 4 so that the turntable 4 rotates through the power of the motor 2. The outside of the driving component is fixedly connected to the turntable 4, and the turntable 4 is used to connect to the extrusion rod 5. The outside of the turntable 4 is rotatably connected to the front side of the work frame 1, and the front side of the turntable 4 is fixedly connected to the extrusion rod 5. The extrusion rod 5 is used to bend the steel bars.

[0038] In this embodiment, in order to achieve guidance before bending the hoop, a guiding component is further included. The guiding component is specifically a limit block 6 fixedly connected to the front side of the working frame 1. The limit block 6 is used to open a limit groove 7. The limit groove 7 is opened on the front side of the limit block 6. The limit groove 7 is used to limit the steel bar and guide it to move toward the bending hoop.

[0039] Again, the transmission mechanism is introduced as follows:

[0040] In this embodiment, the core of the transmission is to arrange two sets of transmission wheel groups with different heights on the outside of the work frame 1, and then form a clamping cavity between the two transmission wheels in the transmission wheel group.

[0041] To move the transmission wheel assembly, you only need to drive one transmission wheel. The steel bar will naturally drive the other transmission wheel to rotate. For example, when you drive transmission wheel one, the steel bar will pull transmission wheel two to move as well. The two transmission wheel assemblies are driven by a pulley assembly. The two rotating wheels in the pulley assembly each drive one transmission wheel assembly to rotate, and then the motor drives the transmission wheels to move.

[0042] Reference Figure 2 As shown, in the specific transmission, the rear side of the work frame 1 is fixedly connected to the motor 2 18, and the motor 2 18 is used to generate power to drive the rotating rod 2 19 to rotate. The driving end of the motor 2 18 is fixedly connected to the rotating rod 2 19, and the rotating rod 2 19 is used to connect to the wheel 1 20. The external rotation of the rotating rod 2 19 is connected to the inside of the work frame 1, and the external rotation of the wheel 1 20 is connected to the inside of the work frame 1. The external rotation of the rotating rod 2 19 is fixedly connected to the wheel 1 20, and the wheel 20 is used to rotate the wheel 2 22 on the outside of the mounting rod 1 21 through the belt 23. The front side of the work frame 1 is rotatably connected to the mounting rod 1 21, and the mounting rod 1 21 is used to fix the wheel 22. The rear side of the outer wall of the mounting rod 21 is fixedly connected to the wheel 22.

[0043] Reference Figure 1 - Figure 2 As shown, the rotating wheel 1 20 and the rotating wheel 2 22 are connected by a belt 23. The belt 23 is used to connect the rotating wheel 1 20 and the rotating wheel 2 22. The external rotation of the rotating wheel 2 22 is connected to the inside of the working frame 1. The external rotation of the transmission wheel 2 26 is connected to the front side of the working frame 1. The external front sides of the rotating rod 2 19 and the mounting rod 1 21 are fixedly connected with the transmission wheel 1 24. The transmission wheel 1 24 is used to rotate and drive the steel bars for transportation. The front side of the working frame 1 is fixedly connected with two mounting rods 25. The mounting rod 25 is used to connect the transmission wheel 2 26. The front sides of the two mounting rods 25 are both rotatably connected with the transmission wheel 2 26. The transmission wheel 2 26 is used to cooperate with the transmission wheel 1 24 to transport the steel bars.

[0044] Finally, the following is an introduction to shear collection:

[0045] Reference Figure 1 - Figure 3 As shown, a hydraulic clamp 8 is provided on the front side of the work frame 1. The hydraulic clamp 8 is used to cut the steel bars. A collection component is provided on the top of the work frame 1. The collection component includes two chutes 9. The chutes 9 are used to allow the slider 10 to slide. The outside of the chute 9 is opened on the top of the work frame 1. The inside of the chute 9 is slidably connected to the slider 10. The slider 10 is used to connect to the collection box 11. The front sides of the two sliders 10 are fixedly connected to the collection box 11. The collection box 11 is used to collect the steel bars that have been bent.

[0046] In this embodiment, the specific working principle is described as follows:

[0047] When the staff is processing the steel bar bending hoop, they first pass one side of the steel bar ring between the transmission wheel 1 24 and the transmission wheel 2 26, then pass between the two iron brushes 17, and then pass through the inside of the limit groove 7 opened on the front side of the limit block 6. Then, when the steel bar needs to be transmitted, the staff starts the motor 2 18, so that the motor 2 18 generates power to drive the rotating rod 2 19 to run, so that the rotating rod 2 19 synchronously drives the rotating wheel 1 20 to rotate, so that the rotating wheel 1 20 rotates and the rotating wheel 2 22 is synchronously driven by the belt 23 to rotate in conjunction with the installation rod 1 21, so that the rotating rod 2 19 and the installation rod 1 21 are rotated. The transmission wheel 1 24 is synchronously driven to rotate, so that the transmission wheel 1 24 cooperates with the transmission wheel 2 26 to transmit the steel bar to the right, and then the steel bar is scraped from the side close to the iron brush 17 to scrape off the rust and impurities on the surface of the steel bar, and then the motor 1 2 is started, so that the motor 1 2 generates power to drive the rotating rod 1 3 to rotate, so that the rotating rod 1 3 drives the turntable 4 to rotate in cooperation with the extrusion rod 5 while bending the steel bar, and then after the bending is completed, the steel bar is shortened by the hydraulic clamp 8, and then bent again, and then the bent steel bar will fall into the interior of the collection box 11 and then collected.
