[0002] The field of rebar cutting technology encompasses the related technologies, equipment, and operating methods for cutting and processing rebar materials in various engineering construction fields such as municipal engineering and building engineering. Its core content is to use various technical means and specialized equipment to cut rebar of different specifications and models into specific lengths or shapes according to engineering design requirements to meet the needs of subsequent construction processes such as rebar connection and binding.

[0003] Laser cutting technology uses a high-power laser beam to precisely heat the steel bars, melting them and cutting them. To effectively control the heat generated during the cutting process, an efficient heat dissipation system is designed between the laser cutting head and the laser source to ensure stable operation of the equipment during long-term use and avoid overheating. Specifically, the generated heat is promptly dissipated through an efficient heat exchange system, while the temperature of the laser cutting area and the laser source is reduced through air cooling or water cooling, thereby preventing equipment malfunctions or decreased cutting accuracy due to overheating. In addition, an adjustable laser power control system is adopted, which can adjust the laser cutting power according to the material and size of different steel bars, thereby improving cutting efficiency and extending the service life of the equipment.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, a bridge rebar cutting device for municipal road construction includes four legs 1. A bearing assembly 2 is fixedly connected to the upper part of each leg 1. A cooling assembly 4 is fixedly connected to the upper right side of the bearing assembly 2. A cutting assembly 3 is slidably connected to the outer surface of the cooling assembly 4. A collecting assembly 5 is fixedly connected to the right side of the bearing assembly 2. A controller 6 is fixedly connected to the rear of the bearing assembly 2. The bearing assembly 2 includes a housing 21. A clamping mechanism 22 for fixing the rebar is rotatably connected inside the housing 21. A transmission mechanism 23 for transmitting the rebar is rotatably connected to the middle of the housing 21. A water storage tank 26 is provided on the right side of the housing 21. A scraping mechanism 24 for cleaning welding slag is fixedly connected to the inner cavity of the water storage tank 26. A fixing block 25 is fixedly connected to the inner cavity of the housing 21. Several guide grooves 27 are provided on the right side of the housing 21. The clamping mechanism 22 includes two bidirectional threaded rods 221. Both bidirectional threaded rods 221 are rotatably connected to the left side of the inner cavity of the housing 21. The outer surfaces of both housings 21 are... Two rotating plates 225 are connected by a thread. A second buckle 224 is rotatably connected to the upper part of the two front rotating plates 225, and a first conveyor belt 222 is rotatably connected to the upper part of the two rear rotating plates 225. The second buckle 224 and the first buckle 223 cooperate to fix the reinforcing bar. A pusher plate 227 is fixedly connected to the bottom of both rotating plates 225 and the first buckle 223. Two springs 226 are fixedly connected to the sides of the two pusher plates 227 that are close to each other. The other side of the two springs 226... The side is fixedly connected to two adjacent rotating plates 225. The front of the outer shell 21 is fixedly connected to a motor 231. The output end of the motor 231 is fixedly connected to a transmission rod 232 through a coupling. A conveyor belt 233 is wound around the outer surface of the transmission rod 232. The scraping mechanism 24 includes a cooperating rod 241. A chuck 242 is fixedly connected to the bottom end of the cooperating rod 241. Two springs 243 are fixedly connected to the bottom end of the chuck 242. The bottom ends of the two springs 243 are fixedly connected to the bottom end of the water storage tank 26.

[0022] In this embodiment, the operator first starts the entire device through the controller 6. After the controller 6 sends the start command, the transmission mechanism 23 in the bearing assembly 2 begins to work. After the motor 231 starts, its output end is tightly connected to the transmission rod 232 through a coupling. The coupling can effectively buffer the impact force generated when the motor 231 starts, reduce the mechanical wear between the motor 231 and the transmission rod 232, and extend the service life of both. Driven by the motor 231, the transmission rod 232 rotates accordingly. The conveyor belt 233 wrapped around the outer surface of the transmission rod 232 begins to move under the friction of the transmission rod 232. The conveyor belt 233 is made of high-strength, high-wear-resistant rubber material, and the surface is also provided with anti-slip texture, which can increase the friction between the steel bar and the steel bar, ensuring that the steel bar will not slip during the conveying process, thereby smoothly conveying the steel bar to the designated cutting position. When the steel bar reaches the appropriate cutting position under the conveyor belt 233, the clamping mechanism 22 in the bearing assembly 2 immediately begins to clamp the steel bar. During the fixing operation of the reinforcing bar, one of the bidirectional threaded rods 221 in the clamping mechanism 22 rotates under the action of the driving device. During the rotation of the bidirectional threaded rod 221, the rotating plate 225, which is threaded to it, moves along the axial direction of the bidirectional threaded rod 221. When the rotating plate 225 moves to a suitable position to effectively clamp the reinforcing bar, a cooperation relationship is formed between the rotating plate 225 and the fixing block 25. Under this cooperation, the pushing plate 227 flips under the elastic action of the spring 226. After flipping, the pushing plate 227 can closely fit the surface of the reinforcing bar and firmly fix the reinforcing bar. The fixing method of this scheme can effectively prevent the reinforcing bar from being displaced due to external force during the subsequent cutting process, thereby ensuring the cutting accuracy. At the same time, the spring 226 has good elastic deformation capability, and its elasticity can be adaptively adjusted according to the different diameters of the reinforcing bars, so that the clamping mechanism 22 can adapt to reinforcing bars of different diameters and specifications. There is no need for the staff to frequently change the fixing parts, which greatly saves the operation time and improves the work efficiency. After the clamping mechanism 22 secures the reinforcing bar, the cutting assembly 3 begins operation. First, the second motor 422 in the support mechanism 42 starts. The output end of the second motor 422 is connected to the one-way threaded rod 424 via a coupling. The coupling effectively compensates for installation errors between the second motor 422 and the one-way threaded rod 424, reducing vibration during transmission and ensuring smooth operation. After the second motor 422 starts, its output rotation drives the one-way threaded rod 424 to rotate synchronously via the coupling. The second transmission belt 425, wound around the outer surface of the one-way threaded rod 424, begins to move under the frictional force of the rod. During its movement... In the middle, the bidirectional threaded rod 221 in the clamping mechanism 22, which drives the rotating plate 225, rotates synchronously, ensuring that the fixing force of the rotating plate 225 on the rebar and the movement rhythm of the cutting component 3 always match, preventing the rebar from shifting due to fluctuations in the fixing force during the cutting process, and further ensuring cutting accuracy. At the same time, during the rotation of the unidirectional threaded rod 424, it cooperates with the two sliding rods 423 set in the inner cavity of the U-shaped plate 421 to ensure the smooth movement of the sliding block 31. Under the rotational driving force of the unidirectional threaded rod 424 and the guiding action of the sliding rods 423, the sliding block 31 in the cutting component 3, which is fixedly connected to the outer surface of the sliding rods 423, moves smoothly along the axial direction of the sliding rods 423. As the sliding block 31 moves, it drives the fixed block 33, which is fixedly connected to it, to move synchronously. When the fixed block 33 moves to the appropriate cutting position, the hydraulic cylinder 32 installed on the upper part of the fixed block 33 is activated. Its output end drives the output rod 34 to slide downward. During the downward sliding process, the output rod 34, through the sliding fit structure between it and the output rod 35, drives the output rod 35 to adjust its height. This sliding fit structure is precisely designed and can achieve accurate adjustment of the height of the output rod 35, so that the laser cutting head installed at the bottom of the output rod 35 can get close to the surface of the steel bar and complete the cutting action. Compared with the traditional mechanical cutting method, no mechanical pressure is generated on the steel bar during the cutting process. The force is applied to reduce burrs at the rebar cut and avoid rebar cut deformation caused by mechanical extrusion, thus significantly improving the cutting quality. In addition, the retaining ring 36 in the cutting component 3 and the telescopic tube 435 in the cooling component 4 form a cooperative relationship, which firmly fixes and limits the output end of the telescopic tube 435, preventing the telescopic tube 435 from shifting or falling off during operation. This ensures that the cooling gas delivered in the inner cavity of the telescopic tube 435 can be directionally delivered to the vicinity of the laser cutting head at the bottom of the output rod 35, and timely cools the laser cutting head and the rebar cutting part during operation, avoiding structural changes due to residual heat accumulation at the rebar cutting point, and ensuring that the mechanical properties of the rebar are not affected.

[0023] It should be noted that: Controller 6 is a conventional technology in the prior art. It integrates a control program and a signal transmission module, which can receive the operating status signals fed back by each component in real time, and send control commands to each component according to the preset working parameters. In this solution, it is only necessary to realize the control of all components such as the bearing component 2, the cutting component 3, and the cooling component 4 using the existing technology.

[0024] Furthermore, by setting the push plate 227 to flip and fix the steel bar under the elastic action of the spring 226, the displacement of the steel bar due to external force during cutting is effectively avoided, ensuring cutting accuracy. At the same time, the good elastic deformation capability of the spring 226 can be adaptively adjusted according to the diameter of the steel bar, allowing the clamping mechanism 22 to adapt to steel bars of different diameters. This eliminates the need for frequent replacement of fixing parts, saves operation time, improves work efficiency, and reduces the operating intensity of workers.

[0025] Example 2 further achieves the purpose of cooling during laser welding, based on Example 1. Please refer to [link / reference]. Figure 7 , Figure 8 , Figure 9 as well as Figure 10As shown, the cooling assembly 4 includes a cooling mechanism 41, with a support mechanism 42 fixedly connected to the bottom of the cooling mechanism 41. The bottom of the support mechanism 42 is fixedly connected to the upper part of the outer casing 21. A heat dissipation assembly 43 is fixedly connected to the bottom of the outer casing 21. The heat dissipation assembly 43 is used to dissipate heat from the water in the inner cavity of the water storage tank 26. The cooling mechanism 41 includes a transfer pump 411, with the bottom of the transfer pump 411 fixedly connected to the support mechanism 42. A second cooling pipe 413 is fixedly connected to the input end of the transfer pump 411, and a first cooling pipe 412 is fixedly connected to the output end of the transfer pump 411. The bottom of the second cooling pipe 413 is fixed... A mating mechanism 414 is connected, and the mating mechanism 414 is wound around the transmission belt 415. A rotating rod 416 is wound around the other side of the transmission belt 415. The mating mechanism 414 includes a housing 4141, the inner cavity of which communicates with the inner cavity of the cooling pipe 413. A pressure block 4142 is fixedly connected to the inner cavity of the housing 4141. An impeller 4143 is rotatably connected to the middle of the housing 4141 near the support mechanism 42. A transmission wheel 4144 is fixedly connected to one side of the impeller 4143. The support mechanism 42 includes a U-shaped plate 421, one side of which is fixedly connected to the transmission belt 4145. A motor 422 is fixedly connected to the cutting assembly 3. A one-way threaded rod 424 is fixedly connected to the output end of the motor 422 via a coupling. Two sliding rods 423 are fixedly connected to the inner cavity of the U-shaped plate 421. The outer surfaces of the two sliding rods 423 are fixedly connected to the cutting assembly 3. A conveyor belt 425 is wound around the front of the one-way threaded rod 424. The other side of the conveyor belt 425 is wound around one of the two-way threaded rods 221. The heat dissipation assembly 43 includes a housing 431. A fan blade 432 is fixedly connected to one side of the housing 431. The output shaft of the fan blade 432 is fixedly connected to a rotating rod 416. Heat dissipation fins 433 are fixedly connected to the upper part of the inner cavity of shell 3 431. A condenser pipe 434 is fixedly connected to the rear of shell 3 431. A telescopic pipe 435 is fixedly connected to the other end of the condenser pipe 434. The cutting component 3 includes a sliding block 31. A fixing block 2 33 is fixedly connected to the left side of the sliding block 31. A drive shaft 32 is fixedly connected to the upper part of the fixing block 2 33. An output rod 1 34 is fixedly connected to the output end of the drive shaft 32. An output rod 2 35 is slidably connected to the bottom of the output rod 1 34. A retaining ring 1 36 is fixedly connected to the rear of the fixing block 2 33. A retaining ring 2 37 is fixedly connected to the rear of the U-shaped plate 421. In a further implementation of this embodiment, during the cutting operation of the cutting component 3, the cooling component 4 simultaneously enters a cooperative working state to ensure the stable operation of the cutting process. First, the transfer pump 411 in the cooling mechanism 41 starts. The transfer pump 411 adopts a high-efficiency centrifugal pump body structure, which has the advantages of large flow rate, high head, and low operating noise, and can provide sufficient power for the delivery of cooling water. The cooling pipe 413 connected to the input end of the transfer pump 411 draws in the cooling water stored in the water storage tank 26 in the bearing component 2. The cooling pipe 413 is made of corrosion-resistant stainless steel with a smooth inner wall, which can reduce... The resistance during water flow is reduced to improve water delivery efficiency. After being pressurized by the transfer pump 411, the cooling water is directionally sprayed from the cooling pipe 412 connected to the output end of the transfer pump 411 towards the periphery of the cutting area. The outlet end of the cooling pipe 412 is equipped with an atomizing nozzle, which can atomize the cooling water into fine water droplets, increasing the contact area with the cutting area and improving the cooling effect. The atomized cooling water and the cooling gas transported by the telescopic pipe 435 form a gas-liquid dual cooling system in the cutting area. This dual cooling method can further enhance the cooling effect, quickly remove the large amount of heat generated during laser cutting, and prevent the temperature of the cutting area from rising due to heat accumulation. To ensure stable cutting, the transmission belt 415 connected to the bottom of the cooling pipe 413 begins to move under the driving force generated by the water flow. The transmission belt 415 uses a high-strength rubber synchronous belt, which has the advantages of high transmission accuracy and good wear resistance. During its movement, the transmission belt 415 drives the mating mechanism 414 and the rotating rod 416 to rotate synchronously. The inner cavity of the outer shell 4141 in the mating mechanism 414 is connected to the inner cavity of the cooling pipe 413, allowing water to smoothly enter the inner cavity of the outer shell 4141. The pressure block 4142 installed inside the outer shell 4141 further pressurizes the water flow. The pressurized water flow increases the pressure of the water flow. When the pressurized water flows inside the outer casing 4141, it drives the impeller 4143 installed inside the outer casing 4141 to rotate. The impeller 4143 adopts a streamlined blade design, which can effectively improve the utilization rate of the water flow and enhance the rotation driving force. During the rotation of the impeller 4143, it drives the transmission wheel 4144 connected to one side to rotate synchronously. The transmission wheel 4144 further enhances the transmission effect of the transmission belt 415 through the friction between it and the transmission belt 415, ensuring that the transmission belt 415 can stably drive the mating mechanism 414 and the rotating rod 416 to rotate. Simultaneously, the rotating rod 416, through a transmission structure wound around its outer surface, drives the cooling pipe 412 to adjust its angle, allowing the atomized cooling water sprayed from the cooling pipe 412 to precisely cover the cutting area, improving the targeting and effectiveness of cooling. During this process, the heat dissipation component 43 installed at the bottom of the inner cavity of the outer shell 21 in the bearing assembly 2 begins to dissipate the cooling water in the inner cavity of the water storage tank 26. The fan blades 432 in the heat dissipation component 43 rotate at high speed under the drive of the rotating rod 416. The fan blades 432 adopt an optimized multi-blade design, which can generate a strong airflow during rotation. This airflow directly acts on the heat dissipation fins 433 installed on the upper part of the inner cavity of the outer shell 431 in the heat dissipation component 43. The heat dissipation fins 433 are made of aluminum alloy with a high thermal conductivity and have undergone special anodizing treatment, increasing the heat dissipation area and enabling... The cooling water in the water tank 26 can quickly transfer heat away after absorbing heat, thus cooling the water. The condenser pipe 434 installed at the rear of the outer shell 3 431 provides a smooth airflow channel for the heat dissipation fins 433, allowing the airflow generated by the fan blades 432 to pass smoothly through the heat dissipation fins 433. At the same time, the refrigerant flowing inside the condenser pipe 434 can cool the airflow after passing through the heat dissipation fins 433, further improving the heat dissipation effect. The telescopic pipe 435, which cooperates with the retaining ring 1 36, obtains the cooled gas from the airflow output end of the heat dissipation component 43, realizing the dual function of the heat dissipation component 43. It can effectively dissipate heat for the cooling water in the water tank 26, ensuring the cooling effect of the cooling water, and can also provide a continuous cooling gas source for the laser cutting head, greatly improving the utilization rate of the component and reducing the overall energy consumption of the device. Furthermore, the atomizing nozzle at the outlet of cooling pipe 412 atomizes the cooling water, increasing the contact area with the cutting area and improving the cooling effect. The atomized cooling water and the cooling gas from the telescopic pipe 435 form a gas-liquid dual cooling system, quickly removing the heat generated by laser cutting, preventing the cutting area from overheating, ensuring the stability of the cutting process, and extending the service life of the laser cutting head. In conjunction with the pressure block 4142 in mechanism 414, the water flow is further pressurized, driving the impeller 4143 to rotate. The streamlined blade design of the impeller 4143 improves water flow utilization and enhances the rotational driving force. The transmission wheel 4144 further enhances the transmission effect of the transmission belt 415. The rotating rod 416 drives the cooling pipe 412 to adjust its angle, allowing the atomized cooling water to... The water-cooling system precisely covers the cutting area, improving the targeting and effectiveness of cooling. The bidirectional threaded rod 221 in the clamping mechanism 22 adopts a high-precision thread processing technology with a reasonable thread profile design, ensuring a tight threaded connection with the rotating plate 225 and smooth transmission. This allows the rotating plate 225 to move precisely to the appropriate clamping position. The pushing plate 227 flips and fixes the reinforcing bar under the elastic action of the spring 226, effectively preventing displacement of the reinforcing bar due to external force during cutting and ensuring cutting accuracy. At the same time, the good elastic deformation capability of the spring 226 can adaptively adjust according to the diameter of the reinforcing bar, allowing the clamping mechanism 22 to adapt to reinforcing bars of different diameters. This eliminates the need for frequent replacement of fixing parts, saves operation time, improves work efficiency, and reduces the operating intensity of workers.

[0026] Example 3 further achieves the purpose of collecting the cut steel bars based on Examples 1 and 2. Please refer to the following for details. Figure 2 As shown, the collection component 5 includes a diversion block 51, which is fixedly connected to the right side of the outer casing 21. Collection chambers 52 are fixedly connected to both the front and rear sides of the diversion block 51. Sliding plates 53 are slidably connected to the inner cavities of the two collection chambers 52. A spring 3 54 is fixedly connected to the bottom of the sliding plate 53.

[0027] In the implementation of this embodiment, after the output rod 2 35 has finished cutting the steel bars, the cut steel bars will cooperate with several guide grooves 27 on the right side of the outer casing 1 21 to separate the cut steel bars. The separated steel bars fall at the sliding plate 53. When the total weight of the accumulated steel bars reaches a certain level, an alarm will be sounded to remind the operator to move them. It should be noted that sensors are installed at the bottom of both collection chambers 52, which only serve as reminders in this solution.

[0028] The working principle of this scheme is as follows: During operation, the entire device is first started by the controller 6. The controller 6 can control the existing technology of each component to ensure the operation of the device. After the controller 6 is started, the transmission mechanism 23 in the bearing component 2 starts to work. The output end of the motor 231 drives the transmission rod 232 to rotate through the coupling. The rotation of the transmission rod 232 causes the conveyor belt 233 wrapped around its outer surface to move. The conveyor belt 233 can smoothly transport the steel bar to the designated cutting position. When the steel bar is transported to the appropriate position, the clamping mechanism 22 begins to fix the steel bar. One of the bidirectional threaded rods 221 rotates, driving the rotating plate 225 connected to it to move. When the rotating plate 225 moves to the appropriate position, through cooperation with the fixing block 25, the pushing plate 227 can be flipped under the elasticity of the spring 226 and fix the steel bar, effectively preventing the steel bar from shifting during the cutting process and ensuring cutting accuracy. At the same time, the elasticity of the spring 226 can adapt to steel bars of different diameters, improving the adaptability of the device to steel bars of different specifications, eliminating the need for frequent replacement of fixing parts and saving operation time.

[0029] Subsequently, the cutting assembly 3 begins operation. Motor 422 in the support mechanism 42 starts, and its output drives a one-way threaded rod 424 to rotate via a coupling. The rotation of the one-way threaded rod 424 causes the transmission belt 425, wound around its front, to move. The transmission belt 425 then drives the bidirectional threaded rod 221 in the clamping mechanism 22, which drives the rotating plate 225, to rotate synchronously. This ensures that the fixing force of the rotating plate 225 on the reinforcing bar matches the movement rhythm of the cutting assembly 3, preventing the reinforcing bar from shifting due to fluctuations in the fixing force during cutting. Simultaneously, the rotation of the one-way threaded rod 424, in conjunction with the two sliding rods 423 inside the U-shaped plate 421, causes the sliding block 31 in the cutting assembly 3, which is fixedly connected to the outer surface of the sliding rods 423, to move smoothly. The sliding block 31 then drives the fixed block 33 to move synchronously. As the unit moves, the hydraulic cylinder 32 on the upper part of the fixed block 33 is activated. The output end of the hydraulic cylinder 32 drives the output rod 34 to slide downward. The output rod 34, through sliding cooperation, drives the output rod 35 to adjust its height, so that the laser cutting head at the bottom of the output rod 35 can accurately approach the steel bar and complete the cutting action. Compared with traditional mechanical cutting, the laser cutting head can reduce the burrs and deformation of the steel bar cut and improve the cutting quality. In addition, the retaining ring 36 cooperates with the telescopic tube 435. The retaining ring 36 fixes and limits the output end of the telescopic tube 435, ensuring that the cooling gas in the inner cavity of the telescopic tube 435 can be directionally delivered to the vicinity of the laser cutting head at the bottom of the output rod 35, so as to cool the laser cutting head and the steel bar cutting part in time and avoid structural changes at the steel bar cutting point due to residual heat. During the cutting process, the cooling components 4 work synchronously and collaboratively. The transfer pump 411 in the cooling mechanism 41 starts, and the cooling pipe 413 at the input end of the transfer pump 411 draws water from the water storage tank 26. After being pressurized by the transfer pump 411, the water is sprayed directionally from the cooling pipe 412 at the output end to the periphery of the cutting area. This forms a gas-liquid dual cooling system with the cooling gas transported by the telescopic pipe 435, further enhancing the cooling effect and quickly removing the large amount of heat generated by laser cutting, ensuring the stability of the cutting process. The transmission belt 415 connected to the bottom of the cooling pipe 413 moves under the driving force of the water flow. The transmission belt 415 drives the mating mechanism 414 and the rotating rod 416 to rotate. The inner cavity of the outer shell 4141 in the mating mechanism 414 is connected to the inner cavity of the cooling pipe 413. When the water flows through the pressure block 4142 in the inner cavity of the outer shell 4141, the pressure increases further. The pressurized water flow will drive the impeller 4143 to rotate, and the impeller 4143 drives the transmission wheel on one side. When 4144 rotates, the transmission wheel 4144 enhances the transmission of the transmission belt 415, and at the same time, the rotating rod 416 connected to the outer surface drives the cooling pipe 412 to output. At this time, the heat dissipation component 43 at the bottom of the inner cavity of the outer shell 21 will dissipate heat from the water in the inner cavity of the water tank 26. The fan blade 432 in the heat dissipation component 43 rotates at high speed under the drive of the rotating rod 416. The airflow generated by the fan blade 432 directly acts on the heat dissipation fins 433 at the upper part of the inner cavity of the outer shell 3 431. The heat dissipation fins 433 quickly dissipate the heat of the water in the water tank 26 after absorbing heat. The condenser pipe 434 at the rear of the outer shell 3 431 provides an airflow channel for the heat dissipation fins 433 and cools the dissipated gas. The telescopic pipe 435 that cooperates with the retaining ring 36 obtains cooling gas from the airflow output end of the heat dissipation component 43, realizing the dual use of the heat dissipation component, which not only dissipates heat from the water tank but also provides a cooling gas source for the laser cutting head, improving the utilization rate of the component. The welding slag and metal debris generated during the cutting process will fall into the water storage tank 26 with the laser cutting airflow and the slight movement of the steel bar. The scraping mechanism 24, which is fixedly connected to the inner cavity of the water storage tank 26, cleans the welding slag in time. The spring 43 at the front of the cooperating rod 241, in cooperation with the bottom of the fixing block 33, will cause the cooperating rod 241 to descend during the cutting process. When the laser head at the bottom of the output rod 35 returns to the initial position after welding, the cooperating rod 241 will rebound under the elastic action of the spring 243, so that the chuck 242 will scrape off the welding slag residue, which is convenient for the staff to clean and recycle the welding slag in the future, reducing the amount of construction waste generated and improving the environmental performance of the device. Finally, the laser-cut steel bar will fall into the inner cavity of the collection chamber 52 on the front and rear sides through the diversion block 51 for collection, so that the operators can handle it later.
