[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] See attached document Figure 3 Appendix Figure 4 and attached Figure 5This utility model provides an embodiment of a rebar cutting device, including a base plate 1, which serves as the basic support structure for the entire device, supporting and stabilizing all other components. Support legs 3 are fixedly connected to the top four sides of the base plate 1, supporting the operating platform 4 and ensuring its stability. The tops of multiple support legs 3 are fixedly connected to the same operating platform 4, providing a platform for rebar placement and cutting operations. A fixing plate 5 is fixedly connected to the top center of the operating platform 4, used to install and provide fixed support for a telescopic rod 6. The telescopic rod 6 is fixedly connected to the right side of the outer wall of the fixing plate 5, and can move a push block 7 by extending and retracting to adjust the position of the rebar. A [missing information - likely a device name] is fixedly connected to the right end of the telescopic rod 6. Push block 7 transmits power to telescopic rod 6, driving the double-acting screw 8, screw ring 12, and clamping plate 11 to move. The double-acting screw 8 is rotatably connected to the bottom inner wall of push block 7. Rotation of the double-acting screw 8 changes the position of the screw ring 12 it engages with. A handle 9 is fixedly connected to the rear end of the outer wall of the double-acting screw 8, allowing the operator to manually rotate it. Two slide rails 10 are provided on the top right side of the operating platform 4, providing a sliding track for the lower slide block 15 to ensure the smooth movement of clamping plate 11. Two clamping plates 11 are slidably connected to the top right side of the operating platform 4, used to clamp reinforcing bars. Two screw rings 12 are fixedly connected to the top of each clamping plate 11, engaging with the double-acting screw 8. When the double-acting screw 8 rotates, it... The movable clamping plate 11 moves, and each of the two clamping plates 11 has a sliding groove 13 at its bottom. The sliding groove 13 cooperates with the upper sliding block 14 to ensure the stability of the movement of the clamping plate 11. The inner walls of the two screw rings 12 are slidably connected to the upper sliding block 14. When the screw rings 12 move, the upper sliding block 14 interacts with the sliding groove 13 to make the clamping plate 11 move smoothly. The bottom of each of the two upper sliding blocks 14 is fixedly connected to the lower sliding block 15. The lower sliding block 15 is engaged in the slide rail 10 and works with the upper sliding block 14 to ensure that the clamping plate 11 moves along the slide rail 10. A cutting assembly is provided on the top left side of the operating table 4. The cutting assembly is used to cut the steel bars. The cutting assembly includes a cutter holder 16. The bottom of the cutter holder 16 is fixedly connected to the top left side of the operating table 4 to make the position of the cutter holder 16 stable and to provide a mounting for the cutter shaft 17. The inner wall of the blade holder 16 is rotatably connected to a blade shaft 17, which provides radial connection for the rotation of the cutting blade 19. A housing 18 is fixedly connected to the rear side of the blade shaft 17, serving a protective function to prevent flying debris during cutting from causing injury. The inner wall of the housing 18 is rotatably connected to the cutting blade 19, which rotates at high speed to cut the reinforcing steel. A handle 20 is fixedly connected to the rear side of the outer wall of the cutting blade 19, transmitting the rotational force of the grip 21 to drive the cutting blade 19 to rotate. A grip 21 is fixedly connected to the rear side of the handle 20, providing a convenient grip for the operator to control the rotation of the cutting blade 19. Multiple finger grooves 22 are provided at the bottom of the grip 21, increasing the operator's grip comfort and stability.A collection mechanism 2 is installed on the bottom left side of the operating table 4. The collection mechanism 2 is used to collect sparks and debris generated during the cutting process.
[0034] Specifically, when the rebar cutting device is in operation, the operator first places the rebar to be cut on the operating table 4, and then rotates the handle 9. Because the handle 9 is fixedly connected to the bidirectional lead screw 8 located at the bottom of the inner wall of the push block 7, the bidirectional lead screw 8 rotates accordingly. Since the front and rear threads of the bidirectional lead screw 8 are in opposite directions, the threaded ring 12 that cooperates with the bidirectional lead screw 8 moves on the lead screw, thereby driving the two clamping plates 11 closer together. At this time, the upper slider 14 is fixed in the threaded ring 12 and moves relative to each other in the sliding groove 13. As the bidirectional lead screw 8 continues to rotate, the two clamping plates 11 move towards each other until... After the reinforcing bar is securely clamped, the telescopic rod 6 connected to the fixing plate 5 retracts, causing the push block 7 to move. The push block 7 then drives the bidirectional screw 8, the screw ring 12, and the clamping plate 11 to move synchronously, moving the clamped reinforcing bar to a suitable cutting position. At this time, the lower slider 15 slides in the slide rail 10. Finally, the operator holds the handle 21 and rotates it downwards. The handle 21 drives the cutting blade 19 to rotate downwards around the blade axis 17 through the blade handle 20. The high-speed rotating cutting blade 19 cuts the reinforcing bar that has been adjusted to the correct position, thus completing the reinforcing bar cutting operation.
[0035] See attached document Figure 1 Appendix Figure 3 and attached Figure 6 The collecting mechanism 2 includes a collecting box 201. The bottom of the outer wall of the collecting box 201 is fixedly connected to the top left side of the base plate 1, so that the collecting box 201 is stably installed on the device. The collecting box 201 is used to store the debris generated during the cutting of steel bars. The top of the collecting box 201 is connected to a collecting port 202, which is used to receive the debris falling from the cutting port 207 on the top left side of the operating table 4. The top of the inner wall of the collecting box 201 is fixedly connected to a guide plate 203, which can guide the debris entering the collecting box 201 along the direction of the cutting port 207. It slides down in an inclined direction. A drawer 204 is slidably connected to the bottom of the inner wall of the collection box 201. The drawer 204 is used to collect and temporarily store debris for easy cleaning. Two protruding strips 205 are fixedly connected to the bottom of the inner wall of the collection box 201. Two grooves 206 are opened at the bottom of the drawer 204. The grooves 206 and the protruding strips 205 interact with each other, so that the drawer 204 can slide smoothly on the bottom of the inner wall of the collection box 201. A cutting opening 207 is opened on the top left side of the operating table 4. The cutting opening 207 provides a falling channel for the debris generated when cutting steel bars.
[0036] Specifically, when the operator cuts the steel bars on the operating table 4, the resulting debris falls downwards through the cutting opening 207 on the top left side of the operating table 4. The collection opening 202 on the top of the collection box 201 is located directly below the cutting opening 207, catching the debris falling from the cutting opening 207. After entering the collection opening 202, the debris falls into the collection box 201. The guide plate 203 inside the collection box 201 guides the debris, causing it to slide down along the inclined direction of the guide plate 203 into the drawer 204. When the debris accumulates to a certain extent, the operator pulls the drawer 204. The groove 206 at the bottom of the drawer 204 slides on the protrusion 205 fixed at the bottom of the inner wall of the collection box 201, pulling the drawer 204 out of the collection box 201 to clean the debris. After cleaning, the operator pushes the drawer 204 back into the collection box 201 along the protrusion 205, and the next round of debris collection can continue. This cycle ensures a clean cutting environment.
[0037] See attached document Figure 1 Appendix Figure 2 and attached Figure 4 Two splash guards 23 are fixedly connected to the top left side of the operating platform 4. The splash guards 23 can prevent debris and sparks generated during the cutting of steel bars from flying to the left, protecting the operator and the surrounding environment. Two scales 24 are provided on the top of the operating platform 4. The scales 24 allow the operator to accurately measure the placement of the steel bars to ensure that the cutting length meets the requirements. Buffer pads 25 are fixedly connected to adjacent sides of the outer walls of the two clamping plates 11. The buffer pads 25 can buffer the steel bars when clamping them, preventing damage to the surface of the steel bars from the clamping plates 11. The outer walls of the two buffer pads 25 are provided with anti-slip textures 26. The anti-slip textures 26 can increase the friction between the buffer pads 25 and the steel bars, making the steel bars more slip-resistant when clamped. The worktable 4 is stable. A discharge plate 27 is fixedly connected to the left side of the outer wall. The discharge plate 27 is used to receive the cut steel bars and facilitate the export of the cut steel bars from the worktable 4. A slide 28 is provided on the top of the discharge plate 27. The slide 28 can guide the cut steel bars to slide down for easy collection. A handle 29 is fixedly connected to the front side of the outer wall of the drawer 204. The handle 29 makes it easy for the operator to pull the drawer 204 to clean up debris. A control cabinet 30 is fixedly connected to the top center of the base plate 1. The control cabinet 30 is used to centrally control some key components of the device. The control cabinet 30 is electrically connected to the telescopic rod 6 and the cutting blade 19 respectively to realize the automatic control of the extension and retraction of the telescopic rod 6 and the operation of the cutting blade 19.
[0038] Specifically, the splash guard 23 prevents debris and sparks generated during cutting from flying to the left, providing reliable protection for operators and the surrounding environment. The two scales 24 on the operating table 4 facilitate operators in measuring the placement of the reinforcing bars, ensuring that the cutting length meets the requirements and improving cutting accuracy. The buffer pads 25 on the outer walls of the two clamping plates 11 cushion the reinforcing bars when clamping them, preventing damage to the surface of the reinforcing bars. The anti-slip textures 26 on the outer walls of the buffer pads 25 increase the friction with the reinforcing bars, making the clamping of the reinforcing bars more stable. The discharge plate 27 and the slide 28 on the left side of the outer wall of the operating table 4 guide the reinforcing bars to slide down, making them easy to collect and improving work efficiency. The handle 29 on the front of the drawer 204 makes it easy to pull the drawer 204. The control cabinet 30 on the top of the base plate 1 centrally controls the telescopic rod 6 and the cutting blade 19, realizing automated operation.
[0039] Working principle: First, the operator places the steel bar to be cut on the operating table 4. After the steel bar is in place, the operator turns the handle 9, which is fixedly connected to the double-acting screw 8. The double-acting screw 8, located at the bottom of the inner wall of the push block 7, rotates accordingly. Since the threads on the front and rear sides of the double-acting screw 8 are opposite, the screw ring 12 that it is engaged with will move on the screw when it rotates. The screw ring 12 is fixed to the top of the clamping plate 11. Both clamping plates 11 have a sliding groove 13 at their bottom, and the lower slider 15 is engaged in the slide rail 10 on the right side of the top of the operating table 4. The upper slider 14 moves relative to the screw in the sliding groove 13. The upper slider 14 is fixed, while the sliding groove 13 moves with the clamping plate 11. As the double-acting screw 8 is held... As the rotation continues, the two clamping plates 11 move towards each other, gradually approaching the reinforcing bar until it is clamped. After clamping, the telescopic rod 6 connected to the fixed plate 5 retracts, driving the push block 7 connected to it to move. The push block 7 drives the bidirectional screw 8, the screw ring 12, and the clamping plate 11 to move synchronously, thereby moving the clamped reinforcing bar to a suitable cutting position. At this time, the upper slider 14 is engaged in the slide groove 13, and the lower slider 15 slides in the slide rail 10. Finally, the cutting operation is carried out. The operator holds the handle 21 and rotates it downwards. The knife handle 20 connected to it drives the cutting knife 19 to rotate downwards around the knife shaft 17. The high-speed rotating cutting knife 19 cuts the reinforcing bar that has been adjusted to the correct position, completing the cutting operation of the reinforcing bar.
[0040] Furthermore, when the operator cuts the steel bars on the operating table 4, the resulting debris falls downwards through the cutting opening 207 on the top left side of the operating table 4. The collection opening 202 on the top of the collection box 201 is located directly below the cutting opening 207, accurately catching the debris falling from the cutting opening 207. After entering the collection opening 202, the debris falls into the collection box 201. The guide plate 203 inside the collection box 201 allows the debris entering the collection box 201 to slide down along the inclined direction of the guide plate 203 to the drawer 204 at the bottom of the collection box 201. When the debris in the drawer 204 accumulates to a certain extent, the operator can pull the drawer 204 and use the sliding of the groove 206 on the protrusion 205 to pull the drawer 204 out of the collection box 201 to clean the debris. After cleaning, the drawer 204 is pushed back into the collection box 201 along the protrusion 205 to continue the next round of debris collection.
[0041] 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.
