[0002] Rebar cutting machines are used in civil engineering to cut rebar to a fixed length. They are an essential piece of equipment in the rebar processing stage. Compared with other cutting equipment, they have the advantages of being lightweight, energy-efficient, reliable, and highly efficient. During the rebar cutting process, the rebar needs to be fixed to ensure that it can be cut stably.

The multiple slots are respectively located on opposite sides of the first and second limiting blocks, and the locking blocks and buckles are located on one side of the limiting components. This utility model utilizes the coordinated arrangement of the base, top seat, measuring tape, and pulling mechanism. The hydraulic cylinder facilitates stable clamping of multiple rebars by the base and top seat.

[0025] Example 1

[0026] Please see Figures 1-4As shown, this utility model provides a technical solution: a rebar clamping mechanism for a rebar cutting machine, including a bearing plate 1. A base 2 and an n-shaped frame 4 are fixedly installed on the left end of the top of the bearing plate 1. A first electric push rod 5 is fixedly installed at both the front and rear ends of the top of the n-shaped frame 4. The extended end of the first electric push rod 5 is fixedly connected to a pressure seat 3 corresponding to the base 2. Guide grooves 6 are opened at both the front and rear ends of the bearing plate 1. A rotating rod 25 is movably connected to the inner side of the guide groove 6 through a bearing. A through groove 24 is opened on the inner surface of the right end of the bearing plate 1, and the right end of the rotating rod 25 passes through the inner side of the through groove 24. A sprocket 33 is fixedly connected to the right side of the rotating rod 25. A chain 31 is sleeved on the outer side of the sprocket 33. A guide roller 26 is fixedly connected to the outer surface of the rotating rod 25. A circulation groove 28 is opened on the outer surface of the guide roller 26. A movable sleeve 32 is slidably connected to the outer surface of the guide roller 26. The movable sleeve 32 is adapted to the guide groove 6, and the movable sleeve 32 slides... Inside the guide groove 6, the top of the inner side of the movable sleeve 32 is fixedly connected to a guide protrusion 27 that slides in the circulating rail groove 28. The top of the movable sleeve 32 is fixedly connected to a movable carrier plate 21. The top of the movable carrier plate 21 is fixedly installed with a fixed clamp 7 and a fixed frame 9. The front and rear ends of the top of the fixed frame 9 are fixedly installed with a second electric push rod 10. The extended end of the second electric push rod 10 is fixedly connected to a movable clamp 8 corresponding to the fixed clamp 7. The right end of the bottom of the bearing plate 1 is fixedly installed with a drive motor 23. The front of the n-shaped frame 4 is fixedly installed with a motor control switch 20. The output end of the motor control switch 20 is connected to the input end of the drive motor 23 via a wire. The output end of the drive motor 23 is fixedly connected to a half gear 29. The right side of the sprocket 33 is fixedly connected to a drive gear 30 that meshes with the half gear 29. The drive gear 30 is located below the half gear 29, and the root circle diameters of the half gear 29 and the drive gear 30 are the same.

[0027] This technical solution: By setting the fixed clamp 7, the steel bar to be processed is fed into its inner side. Power is then supplied to the device via an external power socket. Next, the second electric push rod 10 drives the movable clamp 8 to move downwards within the fixed frame 9, thereby positioning and clamping the steel bar fed into the fixed clamp 7. Then, the motor control switch 20 controls the drive motor 23 to rotate one revolution. When the drive motor 23 is working, it drives the half gear 29 to rotate. Since the root circle diameter of the half gear 29 and the drive gear 30 is the same, when the half gear 29 rotates one revolution… The drive gear 30 rotates half a revolution. When the drive gear 30 rotates, it, with the assistance of the sprocket 33 and chain 31, simultaneously drives the two rotating rods 25 to rotate. The rotation of the rotating rods 25 drives the guide roller 26 to rotate. The rotation of the guide roller 26 forces the guide protrusion 27 to slide within the circulating groove 28. When the guide protrusion 27 moves, it drives the movable carrier plate 21 towards the n-shaped frame 4 via the movable sleeve 32. This allows the positioned and clamped front end of the rebar to be fed between the pressure seat 3 and the base 2 within the n-shaped frame 4. After the movable carrier plate 21 stabilizes, the first electric push... Rod 5 will cause the pressure seat 3 to extend, thereby positioning and clamping the fed steel bar with the cooperation of base 2. Then, the second electric push rod 10 will cause the movable clamp 8 to retract, and with the cooperation of fixed clamp 7, it will release the feeding and clamping of the steel bar. Then, the motor control switch 20 will control the drive motor 23 to rotate one revolution again. The drive motor 23 will drive the drive gear 30 to rotate another half revolution through half gear 29. When the drive gear 30 rotates, it can drive the two rotating rods 25 to rotate simultaneously with the assistance of sprocket 33 and chain 31. When the rotating rods 25 rotate... The guide roller 26 will rotate, and when the guide roller 26 rotates, it will force the guide protrusion 27 to slide in the circulating rail groove 28. When the guide protrusion 27 moves, it can drive the movable carrier plate 21 to move in the opposite direction and reset through the movable sleeve 32. Then, the second electric push rod 10 will drive the movable clamp 8 to move downward in the fixed frame 9 again, so as to reposition and clamp the steel bar in the fixed clamp 7. After the motor control switch 20 controls the drive motor 23 to rotate one revolution, the steel bar can be continuously conveyed without the need for manual operation by workers, saving time and effort and increasing work efficiency.

The front end of the top of the support plate 1 is fixedly installed with a second push rod retraction control seat 18 and a second push rod extension control seat 17 located below the left L-shaped frame 19 and the right L-shaped frame 14, respectively.

[0033] This technical solution: By setting the first push block 12 and the second push block 16, after the device is powered on, and when the first push block 12 and the second push block 16 respectively touch the first push rod retraction control seat 15 and the second push rod extension control seat 17, the second electric push rod 10 will drive the movable clamp 8 to extend, while the first electric push rod 5 will drive the pressure seat 3 to retract. When the movable carrier plate 21 moves towards the n-shaped frame 4, the first push block 12 and the second push block 16 will move synchronously with the fixed frame 9. When the first push block 12 and the second push block 16 respectively touch the first push rod extension control seat 22 and the second push rod retraction control seat 18, the first electric push rod 5 will drive the pressure seat 3 to extend, while the second electric push rod 10 will drive the movable clamp 8 to retract.
