Description

Technical Field

[0001] This utility model relates to the field of burr removal technology on the lower surface of billet ends, specifically a device for removing burrs on the lower surface of billet ends. Background Technology

[0002] The device for removing burrs from the lower surface of billet ends is mainly used in steelmaking production lines. It cleans burrs from the lower surface of billet ends after continuous casting, which can achieve stable purging quality, avoid the generation of rolling surface defects, and reduce the risk of unplanned processes and billet defects flowing into the next process, thus reducing safety hazards.

[0003] Traditional billet burr removal involves manually walking around with a handheld flame gun to clean the burrs on the billet. During this process, it is difficult to maintain a stable horizontal position when manually blowing the flame gun, resulting in some burrs not being completely removed and deep pit defects. Once these defects flow into the next process, they will lead to surface defects on the steel plate. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing burrs from the lower surface of a billet end. The cleaning component fixing frame and connecting rod slide forward inside the U-shaped frame along with the slide plate, ensuring smoothness and consistent blowing depth during the burr removal process by the flame gun. This prevents incomplete removal of sporadic burrs and deep pit defects, which could lead to surface defects on the steel plate. At the same time, the pulley drives the push plate forward, pushing away impurities that fall off during the burr removal process inside the U-shaped frame, preventing impurities from hindering the movement of the device. This solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for removing burrs from the lower surface of a billet end, comprising an inspection frame, a cleaning component mounted on the inspection frame, a rotating component fixedly mounted on the inspection frame, the cleaning component including a U-shaped frame, a sliding plate movably mounted inside the U-shaped frame, a connecting pipe fixedly mounted on the sliding plate, a fixing frame fixedly mounted on the connecting pipe, a flame gun fixedly mounted inside the fixing frame, pulleys fixedly mounted on both sides of the sliding plate, a cylinder fixedly connected to one side of the sliding plate, and a push plate fixedly mounted on the other side of the sliding plate; the rotating component including a motor, a first threaded rod fixedly mounted at the output end of the motor, a first telescopic rod movably mounted on the first threaded rod, one side of the first telescopic rod fixedly connected to one side of the U-shaped frame, a gearbox rotatably connected to one side of the first threaded rod, a second threaded rod rotatably connected to one side of the gearbox, a moving block movably mounted on the second threaded rod, a second telescopic rod fixedly connected to one side of the moving block, a storage box fixedly connected to one side of the second telescopic rod, and a storage box fixedly connected to one side of the U-shaped frame.

[0006] Preferably, the inspection frame is provided with a row of transmission wheels, one side of each transmission wheel is provided with an inclined surface, a rotating rod is fixedly installed on each transmission wheel, and one side of the rotating rod is provided with a thread.

[0007] Preferably, a fixing block is fixedly connected to both sides of the rotating rod, and the fixing blocks are fixedly installed on the inspection table.

[0008] Preferably, a damper is fixedly connected to one side of the connecting pipe, and a fixing rod is fixedly connected to the other side of the damper.

[0009] Preferably, the first threaded rod and the second threaded rod are rotatably mounted on the inspection table on one side, and the first threaded rod and the second threaded rod extend through the inspection table on the other side, and both the first threaded rod and the second threaded rod are rotatably connected to the gearbox.

[0010] Preferably, the gearbox has two sets of gears inside, each of which has two sets of bevel gears meshing, and a connecting rod is provided between the two sets of gears.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The flame gun slides forward inside the U-shaped frame along the fixed frame and connecting rod, ensuring that the flame gun remains smooth and the blowing depth is consistent during the deburring process. This prevents the removal of sporadic burrs and deep pits, which can lead to defects on the steel plate surface. At the same time, the pulley drives the push plate to move forward, pushing away the impurities that fall off during the deburring process inside the U-shaped frame, preventing the impurities from hindering the movement of the device.

[0013] 2. The motor drives the first threaded rod to rotate, and through the power transmission of the gearbox, the second threaded rod rotates. The first telescopic rod and the second telescopic rod drive the cleaning component and storage box to move on the inspection table to the designated cleaning location, avoiding the safety hazard of operators falling during walking.

[0014] 3. The damping causes the fixed rod to undergo elastic deformation and rebound, and the fixed rod is engaged in the thread. Then, the slide plate drives the fixed rod to move backward. Under the guidance of the thread, the fixed rod drives the rotating rod to rotate, thereby driving the transmission wheel to rotate, transmitting the blank for feeding. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figures 1 to 4 This utility model provides a device for removing burrs from the lower surface of the end of a billet, including an inspection frame 1, which is used to fix and support the operation of the overall equipment. A cleaning component 2 is installed on the inspection frame 1 to clean the burrs from the lower surface of the end of the billet. A rotating component 3 is fixedly installed on the inspection frame 1 to drive the cleaning component 2 to move, thereby avoiding the safety hazard of the operator falling during the walking process.

[0022] Cleaning component 2 includes a U-shaped frame 201, which ensures the height and angle of the flame gun's blowing. A sliding plate 202 is movably mounted inside the U-shaped frame 201, serving as a fixing device. A connecting pipe 203 is fixedly mounted on the sliding plate 202, also for fixing the device. A fixing bracket 204 is fixedly mounted on the connecting pipe 203, further securing the device. A flame gun 205 is fixedly mounted inside the fixing bracket 204, used for flame cleaning the burrs on the lower surface of the blank end. Pulleys 208 are fixedly mounted on both sides of the sliding plate 202, driving the device to slide smoothly, ensuring consistent blowing depth during burr cleaning and preventing incomplete removal of sporadic burrs or deep pits that could lead to surface defects on the steel plate. One side of the sliding plate 202 is fixed... A cylinder 206 is fixedly connected to the slide plate 202, which drives the slide plate 202 to move. A push plate 207 is fixedly installed on the other side of the slide plate 202. The push plate 207 moves with the slide plate 202 and pushes the U-shaped frame to remove impurities that fall during the deburring process. When cleaning the lower surface burrs of the billet end, the cylinder 206 is activated to drive the slide plate 202 to move through the pulley 202. The flame gun slides forward inside the U-shaped frame 201 through the fixed bracket 204 and the connecting rod, ensuring that the flame gun remains smooth and the blowing depth is consistent during the deburring process. This prevents the removal of sporadic burrs and deep pit defects, which can lead to defects on the steel plate surface. At the same time, the pulley 202 drives the push plate 207 to move forward, pushing the impurities that fall during the deburring process inside the U-shaped frame 201 to prevent the impurities from hindering the movement of the device.

[0023] The rotating component 3 includes a motor 301, which is the power source for the entire device and provides power output. A first threaded rod 302 is fixedly installed at the output end of the motor 301, driving the first threaded rod 302 to rotate. A first telescopic rod 303 is movably installed on the first threaded rod 302, causing the first threaded rod 302 to move. One side of the first telescopic rod 303 is fixedly connected to one side of the U-shaped frame 201, driving the cleaning component 2 to move. A gearbox 308 is rotatably connected to one side of the first threaded rod 302, transmitting power through the gearbox 308. A second threaded rod 304 is rotatably connected to one side of the gearbox 308, causing the second threaded rod 304 to rotate. A moving block 305 is movably installed on the second threaded rod 304, causing the moving block 305 to move. A second telescopic rod 306 is fixedly connected to one side of the moving block 305. The telescopic rod 306 moves along with the moving block 305. A storage box 307 is fixedly connected to one side of the second telescopic rod 306. The second telescopic rod 306 drives the storage box 307 to move. One side of the storage box 307 is fixedly connected to the other side of the U-shaped frame 201. When the push plate 207 cleans the burrs inside the U-shaped frame 201, the impurities that fall into the storage box 307 are pushed into the storage box 307, making it easier for the construction personnel to clean. When the construction personnel start the first telescopic rod 303 and the second telescopic rod 306 to extend, the first telescopic rod 303 and the second telescopic rod 306 will drive the cleaning component 2 and the storage box 307 to rise. Then the motor 301 is started. The motor 301 drives the first threaded rod 302 to rotate. Through the power transmission of the gearbox 308, the second threaded rod 304 rotates. The first telescopic rods 303 and 305 are driven by the second telescopic rod 306. The cleaning component 2 and the storage box 307 move on the inspection table 1 to the designated cleaning location, avoiding the safety hazard of the operator falling during the process.

[0024] In an optional embodiment, the inspection stand 1 is provided with a row of transmission wheels 103. The transmission wheels 103 are used to move the blank and feed it. One side of the transmission wheel 103 is provided with an inclined surface. A rotating rod 102 is fixedly installed on the transmission wheel 103. The rotating rod 102 drives the transmission wheel 103 to rotate. One side of the rotating rod 102 is provided with a thread for the rotating rod 102 to rotate.

[0025] In an optional embodiment, fixing blocks 101 are fixedly connected to both sides of the rotating rod 102. The fixing blocks 101 are fixedly installed on the inspection table 1. The fixing blocks are used to fix the rotating rod 102 and support the rotation of the rotating rod 102.

[0026] In an optional embodiment, a damper 209 is fixedly connected to one side of the connecting pipe 203. The damper 209 is used to undergo elastic deformation to drive other devices to operate. A fixed rod 210 is fixedly connected to one side of the damper 209 for threaded engagement with one side of the rotating rod 102. As the connecting pipe 203 moves forward with the slide plate 202, the damper 209 also moves forward with the connecting pipe 203. When moving forward, the damper 209 is constantly subjected to pressure from the transmission wheel 103 through the fixed rod 210, and the damper 209 is always in a compressed state. When the damper 209 moves to the thread of the rotating rod, the transmission wheel 103 no longer applies pressure to the damper 209. The damper 209 drives the fixed rod 210 to undergo elastic deformation and rebound. The fixed rod 210 engages with the thread, and then the slide plate 202 drives the fixed rod 210 to move backward. Under the guidance of the thread, the fixed rod 210 drives the rotating rod 102 to rotate, thereby driving the transmission wheel 103 to rotate, transporting the blank, and feeding the material.

[0027] In an optional embodiment, the first threaded rod 302 and the second threaded rod 304 are rotatably mounted on the inspection table 1 on one side to fix and support the rotation of the first threaded rod 302 and the second threaded rod 304. The other side of the first threaded rod 302 and the second threaded rod 304 extends through the inspection table 1, and both the first threaded rod 302 and the second threaded rod 304 are rotatably connected to the gearbox 308. The first threaded rod 302 and the second threaded rod 304 drive the gearbox 308 to rotate, thereby transmitting power.

[0028] In an optional embodiment, the gearbox 308 has two sets of gears inside, each set of gears having two sets of bevel gears meshing together. A connecting rod is provided between the two sets of gears. The first threaded rod drives one of the gear sets to rotate, and the rotation is transmitted to the other gear set through the connecting rod. The other gear set drives the second threaded rod 304 to rotate.

[0029] Working principle: When cleaning burrs on the lower surface of the billet end, the starting cylinder 206 drives the sliding plate 202 to move via the pulley 202. The flame gun slides forward inside the U-shaped frame 201 along with the sliding plate via the fixed frame 204 and connecting rod, ensuring smooth cleaning and consistent blowing depth during the burr removal process. This prevents incomplete removal of sporadic burrs and deep pit defects that could lead to surface defects on the steel plate. Simultaneously, the pulley 202 drives the push plate 207 to move forward, pushing away impurities that fall during burr removal inside the U-shaped frame 201, preventing impurities from obstructing the movement of the device. The first telescopic rod 303 and the second telescopic rod 306 are then extended, raising the cleaning assembly 2 and the storage box 307. Then, the motor 301 is started, driving the first threaded rod 302 to rotate. Through the power transmission of the gearbox 308, the second threaded rod 304 rotates, and the first telescopic rod 303 and the second threaded rod 304 move forward. 05 Driven by the second telescopic rod 306, the cleaning component 2 and the storage box 307 move on the inspection table 1 to the designated cleaning location, avoiding the safety hazard of operators falling during walking. As the connecting pipe 203 moves forward with the slide plate 202, the damper 209 also moves forward with the connecting pipe 203. When moving forward, the damper 209 is constantly under pressure from the transmission wheel 103 through the fixed rod 210, and the damper 209 is always in a compressed state. When the damper 209 moves to the thread of the rotating rod, the transmission wheel 103 no longer applies pressure to the damper 209, and the damper 209 causes the fixed rod 210 to undergo elastic deformation and rebound. The fixed rod 210 is engaged in the thread, and then the slide plate 202 drives the fixed rod 210 to move backward. Under the guidance of the thread, the fixed rod 210 drives the rotating rod 102 to rotate, thereby driving the transmission wheel 103 to rotate, transmitting the blank and feeding the material.
