[0008] Preferably, the cutting component includes a fixed seat fixedly installed on the upper end face of the base. The fixed seat is located between two adjacent sets of fixed frames. A threaded rod is rotatably embedded through the upper inner edge of the fixed seat. A threaded sleeve is screwed onto the outer side of the threaded rod. A support frame is embedded on the outer surface of the threaded sleeve. A first servo motor is connected to the upper end of the support frame. A cutter is coaxially mounted on the output shaft of the first servo motor. The cutter is located on the lower side of the drum.
[0009] Preferably, two sets of guide rods are symmetrically fixedly installed at the lower inner edge of the fixed base, and two sets of guide sleeves are respectively attached to the outer surfaces of the two sets of guide rods.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The set winding mechanism, driven by the No. 3 servo motor and driven gears, rotates the drum, thereby winding the steel bar onto the surface of the drum. Then, the No. 1 servo motor drives the cutter to rotate, while the No. 2 servo motor drives the threaded rod to rotate, which in turn drives the threaded sleeve tightened on the threaded rod to move. At this time, the guide sleeve slides on the guide rod to assist the movement of the threaded sleeve, so that the rotating cutter can contact and cut the wound steel bar. This completes the dual process of cutting and winding the steel bar, meeting its usage requirements.
[0014] 2. By setting multiple sets of idlers, multiple steel bars can be supported and guided by multiple sets of limiting rings on the idlers. This allows for the simultaneous processing of multiple steel bars, improving processing efficiency. The T-shaped frame can be directly pushed, and the support rod slides in the guide seat, allowing the T-shaped frame to pass through the connecting frame. Then, the pin is inserted into the T-shaped frame and the connecting frame for fixation, thus fixing the moving limiting plate. Multiple sets of limiting plates support the ends of the steel bars, making the ends of multiple steel bars coplanar, which ensures that the length of the multiple steel bars is consistent after cutting.
[0015] 3. By directly rotating the threaded column, two sets of threaded rings can be moved towards each other. The inclined top support is used to push the top seat, which moves vertically upward under the guidance of the directional sleeve and directional column. This presses the top seat against the end of the reinforcing bar, thereby pressing and fixing multiple reinforcing bars onto the drum at the same time. The reinforcing bars are also locked in the bar-locking groove in the top seat for limitation, which facilitates the simultaneous fixing of multiple reinforcing bars and effectively ensures ease of use.

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0027] like Figures 1-9 The present invention relates to a steel bar shearing device for pile foundation construction, comprising a base 1, a coil installed at the upper rear edge of the base 1, a roller 8 above the base 1, a fixing frame 7 rotatably embedded at the lower front and rear ends of the roller 8, the lower end of the fixing frame 7 being fixedly connected to the base 1, multiple sets of limiting rings 9 being coaxially embedded on the outer surface of the roller 8, a cutter installed at the upper end of the base 1, the cutter being located between two adjacent sets of fixing frames 7, the cutter being located on the side and below the coil, and a limiting component installed at the upper side edge of the base 1.
[0028] The coil includes a frame 2 embedded in the upper rear edge of the base 1. A drive shaft 39 is rotatably embedded through the lower inner side of the frame 2, which serves as a load-bearing component. A drive gear 40 is coaxially embedded on the outer surface of the drive shaft 39. A third servo motor 38 is fixedly installed at the rear end of the frame 2. The output shaft of the third servo motor 38 is fixedly connected to the end of the drive shaft 39. The third servo motor 38 drives the drive shaft 39 to rotate. A bearing shaft 41 is rotatably embedded through the upper inner side of the frame 2. A drum 3 is coaxially fixedly installed at the front end of the bearing shaft 41. The drum 3 serves to roll the reinforcing bar 44 into a circle.
[0029] A driven gear 42 is coaxially inlaid on the outer surface of the bearing shaft 41. The driven gear 42 meshes with the drive gear 40. The driven gear 42 and the drive gear 40 are located inside the frame 2. A bearing frame 5 is installed below the drum 3. The driven gear 42 and the drive gear 40 serve to connect the bearing shaft 41 and the drive shaft 39 together. A threaded column 21 is rotatably inlaid inside the bearing frame 5. The threads at both ends of the threaded column 21 are symmetrically arranged, which can drive two sets of threaded rings 22 to move towards each other. Two sets of threaded rings 22 are symmetrically screwed on the outer side of the threaded column 21. Two sets of top fixing brackets 24 are respectively installed obliquely on the upper ends of the two sets of threaded rings 22. The two sets of top fixing brackets 24 are symmetrically arranged. The upper ends of the two sets of top fixing brackets 24 are connected to the top seat 25. The top fixing brackets 24 serve to support the top seat 25.
[0030] A first connecting frame 23 extends from the upper end face of the threaded ring 22. The lower end of the top fixing frame 24 is rotatably connected to the interior of the first connecting frame 23. Two sets of second connecting frames 31 extend symmetrically from the lower end face of the top seat 25. Both the first connecting frame 23 and the second connecting frame 31 serve as connections. The upper end of the top fixing frame 24 is rotatably connected to the interior of the second connecting frame 31. The rear end of the bearing frame 5 is fixedly connected to the rear edge of the outer surface of the drum 3. Multiple sets of reinforcing bar grooves 26 are provided on the upper end face of the top seat 25. Two sets of lugs 20 extend symmetrically from the outer surface of the threaded ring 22. The reinforcing bar grooves 26 are used to engage the reinforcing bar 44 and prevent the reinforcing bar 44 from shifting forward or backward. The top seat 25 serves to tighten and fix the reinforcing bar 44 onto the drum 3. Both sides of the bearing frame 5 are provided with sliding grooves 19, and the lugs 20 fit into the inside of the sliding grooves 19. The lugs 20 and the sliding grooves 19 ensure that the threaded ring 22 moves in a straight line and does not rotate. A handwheel is coaxially installed at the end of the threaded column 21. The front and rear edges of the upper end of the bearing frame 5 are inlaid with directional sleeves 28. The directional column 27 is fitted into the inside of the directional sleeve 28 and is fixedly connected to the top seat 25. The directional sleeves 28 and the directional column 27 guide the top seat 25, so that the top seat 25 can move vertically up and down.
[0031] The cutting tool includes a fixed seat 10 fixedly installed on the upper surface of the base 1. The fixed seat 10 is located between two adjacent sets of fixed frames 7. A threaded rod 12 is rotatably embedded through the upper edge of the inner side of the fixed seat 10. A threaded sleeve 13 is screwed onto the outer side of the threaded rod 12. A support frame 14 is embedded on the outer surface of the threaded sleeve 13. The threaded rod 12 and the threaded sleeve 13 drive the cutter 6 to move back and forth. A first servo motor 15 is connected to the upper end of the support frame 14. The cutter 6 is coaxially mounted on the output shaft of the first servo motor 15. The cutter 6 is located on the side and below the drum 3. The first servo motor 15 drives the cutter 6 to rotate.
[0032] Two sets of guide rods 17 are symmetrically fixedly installed at the lower inner edge of the fixed base 10. Two sets of guide sleeves 18 are respectively attached to the outer surface of the two sets of guide rods 17. The two sets of guide sleeves 18 are respectively fixedly connected to the lower two sides of the support frame 14. A second servo motor 16 is fixedly installed on the front end face of the fixed base 10. The output shaft of the second servo motor 16 is fixedly connected to the end of the threaded rod 12. The second servo motor 16 drives the threaded rod 12 to rotate. An extension frame 11 is fixedly installed at the front end of the base 1 at an angle. The end of the extension frame 11 is fixedly connected to the fixed base 10. The extension frame 11 serves to reinforce the fixed base 10.
[0033] The limiting component includes multiple sets of limiting discs 29 arranged in a linear array above the base 1. Connecting blocks 43 are embedded between the multiple sets of limiting discs 29, which serve to fix the multiple sets of limiting discs 29 together. The limiting discs 29 are located on the side of the top seat 25. Two sets of support rods 30 are coaxially embedded on the sides of the two sets of limiting discs 29 located at both ends. Two sets of guide seats 33 are respectively attached to the outer surfaces of the two sets of support rods 30. A connecting frame 34 is embedded between the two sets of guide seats 33. The support rods 30 and guide seats 33 serve to ensure the linear movement of the limiting discs 29.
[0034] Two sets of push caps 36 are coaxially embedded at the ends of the two sets of support rods 30. A T-shaped frame 4 is fixedly installed between the two sets of push caps 36. The T-shaped frame 4 fits and passes through the middle of the side of the connecting frame 34. A pin 35 is installed through the middle of the upper end face of the connecting frame 34 and the upper end face of the T-shaped frame 4. A support frame 32 is fixedly installed at the lower end of the guide seat 33. The pin 35 serves to fix the connecting frame 34 and the T-shaped frame 4. The return spring 37 can push the push caps 36, thereby pushing the support rods 30, so that the limiting plate 29 moves and resets. The end of the support frame 32 is fixedly connected to the base 1. A return spring 37 is wound around the outside of the support rods 30. The return spring 37 is located between the guide seat 33 and the push caps 36.
[0035] During shearing, multiple reinforcing bars 44 are placed on multiple sets of idler rollers 8, with each reinforcing bar 44 positioned between multiple sets of limiting rings 9. Then, the T-shaped frame 4 is directly pushed, causing the support rod 30 to slide within the guide seat 33, allowing the T-shaped frame 4 to pass through the connecting frame 34. Next, the pin 35 is inserted into the T-shaped frame 4 and the connecting frame 34 for fixation, thus securing the moving limiting disc 29. The multiple reinforcing bars 44 are then pushed, causing their ends to press against the limiting discs 29. At this point, the threaded column 21 is rotated, causing the two sets of threaded rings 22 to move towards each other. The inclined top fixing frame 24 pushes the top seat 25, causing it to move vertically upward under the guidance of the directional sleeve 28 and the directional column 27, pressing it against the end of the reinforcing bar 44, thus simultaneously pressing multiple reinforcing bars 44. The steel bar 44 is fixed on the drum 3 and is limited in the groove 26 of the top seat 25. Then, the pin 35 is pulled out from the connecting frame 34 and the T-shaped frame 4, so that the limiting plate 29 moves and resets under the push of the return spring 37. Then, the third servo motor 38 drives the drum 3 to rotate through the drive gear 40 and the driven gear 42, thereby winding the steel bar 44 onto the surface of the drum 3. Then, the first servo motor 15 drives the cutter 6 to rotate, and at the same time, the second servo motor 16 drives the threaded rod 12 to rotate, so as to drive the threaded sleeve 13 tightened on the threaded rod 12 to move. At this time, the guide sleeve 18 slides on the guide rod 17 to assist the movement of the threaded sleeve 13, so that the rotating cutter 6 can contact and cut the rolled steel bar 44, thus completing the dual process of cutting and rolling the steel bar 44.
