It can automatically cut the continuous casting billet into products of suitable size according to the preset length, such as plates, profiles, etc. The automatic cutting device for steelmaking and continuous casting generally adopts flame cutting.

The patent with patent announcement number CN220970715U discloses a new type of continuous casting automatic cutting device, which relates to the technical field of continuous casting automatic cutting devices. The automatic cutting device aims to solve the technical problems that the continuous casting automatic cutting device in the prior art is difficult to use at the steelmaking continuous casting site, and it is difficult to quickly adjust and fix the position of the flame cutting head. The automatic cutting device includes a balance beam and U-shaped blocks fixedly installed at the left and right ends of the balance beam; a first limit groove is fixedly opened at the upper end of the balance beam, and a movable block is movably provided on the inner wall of the first limit groove, and a servo mechanism is fixedly installed on the upper end of the movable block, and a moving block is fixedly installed on the outer wall of the lead screw nut of the servo mechanism, and a flame cutting machine is fixedly installed on the upper end of the moving block. The automatic cutting device can be used at the steelmaking continuous casting site, and the position of the flame cutting head can be quickly adjusted and fixed.

However, the current automatic cutting device for continuous casting has the following problems: when the automatic cutting device for continuous casting uses clamps to clamp the continuous casting billet, when there is slag on the side wall of the continuous casting billet, the slag will cause the side wall of the continuous casting billet clamped by the clamp to be uneven, making it impossible for the clamp to apply clamping force evenly, which will result in loose clamping or insufficient clamping force in some areas, affecting the stability and accuracy of the continuous casting billet cutting process, and spark particles will fly during the cutting process. At the same time, the outer wall of the transmission guide roller is easily adhered to slag. Therefore, we proposed an automatic cutting device for steelmaking continuous casting.

To achieve the above objectives, the present invention is implemented through the following technical scheme: an automatic cutting device for steelmaking continuous casting, comprising a device body, a track plate, and a mobile trolley, wherein track plates for driving the mobile trolley to move are fixed on both sides of the device body, a U-shaped beam is fixed between the tops of the two mobile trolleys, a control device is fixed on the top of the U-shaped beam, a clamp control device and a flame cutting device are respectively arranged on both sides of the control device, two clamp bodies are arranged at the bottom of the clamp control device, a plurality of guide rollers are rotatably installed inside the device body, a circular groove frame is fixed on the side of the clamp control device away from the U-shaped beam, a screw is vertically rotatably installed on the middle part of the inner wall of the circular groove frame, and the screw is driven by a motor, the external thread of the screw is connected to a U-shaped sliding rod, and the U-shaped sliding rod is slidably installed inside the circular groove frame, and a sliding column is transversely penetrated and slidably installed on the side where the two legs of the U-shaped sliding rod are away from each other, and the sliding column and the support of the U-shaped sliding rod are The two ends of the U-shaped support frame are fixed with a spring, and the two ends of the U-shaped support frame are slidably mounted on the two ends of the U-shaped support frame.

According to the above technical solution, a T-shaped rod is vertically penetrated and slidably installed on the top of the inner wall of the U-shaped scraper, and a spring is arranged between the T-shaped rod and the bottom of the inner wall of the U-shaped scraper, a spring plate is fixed on the top of the T-shaped rod, and sliders are fixed on both sides of the spring plate. A strip groove for sliding two sliders is opened on the top of the U-shaped scraper, and a through groove for sliding the T-shaped rod is opened on the top of the two triangular scrapers, and a semicircular block is fixed on the bottom of the inner wall of the through groove of the triangular scraper, and a plurality of semi-arc blocks are fixed on the bottom of the T-shaped rod, and the semi-arc blocks of the T-shaped rod are located at the triangular On the movement trajectory of the semicircular block of the scraper, when the triangular scraper is retracted into the interior of the U-shaped scraper, the semicircular block of the triangular scraper pushes the semi-arc block of the T-shaped rod to drive the T-shaped rod to move upward. When the semicircular block of the triangular scraper no longer pushes the semi-arc block of the T-shaped rod, the T-shaped rod is reset and moves downward under the action of the spring force corresponding to the T-shaped rod, and so on. The T-shaped rod will intermittently push the middle part of the spring plate to move upward. Since the positions on both sides of the spring plate are restricted by the slider, the spring plate will intermittently bulge and deform, so that the spring plate will push the slag falling on the surface of the U-shaped scraper to the positions on both sides.

According to the above technical solution, the splash-proof device includes two sleeves, which are respectively fixed on both sides of the inside of the device body, and the sleeves are sleeved on the outside of several guide rollers. Two connecting rods are penetrated and slidably installed on the sides of the two sleeves close to each other, and a spring is provided between the connecting rod and the sleeve, and several baffles are evenly and equidistantly fixed between the outsides of two adjacent connecting rods. A semicircular groove matching the guide roller is provided on the top of the baffle. Spark particles will be generated when the flame cutting device cuts the continuous casting billet, and the sleeve drives the baffle through the connecting rod to block the spark particles generated during the flame cutting.

The inclined surface of the triangular block is located on the semi-arc motion trajectory of the resistance rod. When the U-shaped beam moves, the U-shaped beam drives the resistance rod to move with it.

The V-shaped groove plate is fixed to the side of the track plate away from the device body, and the V-shaped groove plate is located at the cutting starting point of the flame cutting device. The bottom of the elastic telescopic rod is arranged in a round block shape, and a V-shaped groove is provided on the top of the V-shaped groove plate. The V-shaped groove of the V-shaped groove plate is used to accommodate the round block shape of the elastic telescopic rod. Chamfers are provided on both sides of the top of the V-shaped groove plate, and the mobile trolley is connected to the U-shaped beam and the control device belt. When the dynamic flame cutting device moves to the cutting starting point, the U-shaped beam will drive the fixed rod to move, and the fixed rod will drive the elastic telescopic rod to move. When the elastic telescopic rod moves to the chamfered position of the V-groove plate, the chamfered inclined surface of the V-groove plate pushes the round block of the elastic telescopic rod to squeeze the telescopic end of the elastic telescopic rod until the round block of the elastic telescopic rod passes the chamfer of the V-groove plate and enters the V-groove plate part of the V-groove plate. Each time the U-shaped slide bar moves downward, the U-shaped slide bar drives the elastic telescopic rod to move downward through the fixed rod, and the round block of the elastic telescopic rod moves downward accordingly. The V-groove inclined surface of the V-groove plate will guide the position of the elastic telescopic rod through the round block of the elastic telescopic rod.

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Please refer to Figures 1-7. An embodiment of the present invention is: an automatic cutting device for steelmaking continuous casting, comprising a device body 1, a plurality of guide rollers 2 are rotatably installed inside the device body 1, track plates 3 are fixed on both sides of the device body 1, and the tops of the two track plates 3 are movably connected with moving trolleys 4, a U-shaped beam 8 is fixed between the tops of the two moving trolleys 4, a control device 7 is fixed on the top of the U-shaped beam 8, a clamp control device 9 is fixed on one side of the control device 7, and two clamp bodies 11 are arranged at the bottom of the clamp control device 9, and the control device 7 A flame cutting device 71 is fixed on the other side of the clamp control device 9, and a round-shaped groove frame 10 is fixed on the side away from the U-shaped beam 8. A screw rod 12 is vertically rotatably installed in the middle of the inner wall of the round-shaped groove frame 10, and the screw rod 12 is driven by a motor. The external thread of the screw rod 12 is connected to a U-shaped slide rod 14, and the U-shaped slide rod 14 is slidably installed inside the round-shaped groove frame 10. A slide column 13 is horizontally penetrated and slidably installed on the side where the two legs of the U-shaped slide rod 14 are away from each other, and a spring is provided between the slide column 13 and the legs of the U-shaped slide rod 14. The two slide columns 13 are close to each other. A U-shaped scraper 15 is fixed on one side, and an opening for accommodating the U-shaped scraper 15 is opened at the bottom of the two clamp bodies 11. An I-shaped frame 17 is fixed inside the U-shaped scraper 15. Triangular scrapers 16 are slidably installed on both sides of the outer wall of the I-shaped frame 17. A spring is arranged between the two triangular scrapers 16. Through the arrangement of the above structure, the U-shaped scraper 15 and the triangular scraper 16 can scrape off the steel slag adhered to the side wall of the continuous casting billet, thereby achieving the purpose of cleaning the side wall of the continuous casting billet, thereby avoiding the steel slag causing the side wall of the continuous casting billet clamped by the clamp body 11 to be uneven , which makes it impossible for the clamp body 11 to apply the clamping force evenly, affecting the stability and accuracy of the continuous casting billet cutting process; at the same time, through the setting of the above-mentioned structure, the open side wall of the clamp body 11 will push the inclined surface of the triangular scraper 16 to drive the triangular scraper 16 to retract into the interior of the U-shaped scraper 15. After the triangular scraper 16 is retracted into the interior of the U-shaped scraper 15, the clamp body 11 can effectively clamp the side wall of the continuous casting billet. The interior of the device body 1 is provided with a splash-proof device 5 for limiting the diffusion range of spark particles and cleaning the slag adhered to the outer wall of the guide roller 2.

A T-shaped rod 20 is vertically penetrated and slidably installed on the top of the inner wall of the U-shaped scraper 15, and a spring is provided between the T-shaped rod 20 and the bottom of the inner wall of the U-shaped scraper 15, a spring plate 19 is fixed on the top of the T-shaped rod 20, and sliders 18 are fixed on both sides of the spring plate 19, and a strip groove for the sliding of two sliders 18 is opened on the top of the U-shaped scraper 15, and a through groove for the sliding of the T-shaped rod 20 is opened on the top of the two triangular scrapers 16, and a semicircular block is fixed at the bottom of the inner wall of the through groove of the triangular scraper 16, and a plurality of semi-arc blocks are fixed at the bottom of the T-shaped rod 20, and the semi-arc blocks of the T-shaped rod 20 are located on the semi-circular block movement trajectory of the triangular scraper 16. Through the arrangement of the above structure, the spring plate 19 will intermittently bulge and deform, so that the spring plate 19 pushes the slag falling on the surface of the U-shaped scraper 15 to the positions on both sides, thereby avoiding the problem of slag adhering to the surface of the U-shaped scraper 15 and affecting the efficiency of the U-shaped scraper 15 in scraping slag on the surface of the continuous casting billet.

The splash-proof device 5 comprises two sleeve plates 51, which are respectively fixed on both sides of the interior of the device body 1, and the sleeve plates 51 are sleeved on the outside of a plurality of guide rollers 2. Two connecting rods 53 are penetrated and slidably installed on the sides of the two sleeve plates 51 close to each other, and a spring is provided between the connecting rod 53 and the sleeve plates 51. A plurality of baffles 52 are evenly and equidistantly fixed between the outsides of two adjacent connecting rods 53, and a semicircular groove matching the guide roller 2 is provided on the top of the baffle plate 52. Through the arrangement of the above structure, the sleeve plate 51 drives the baffle plate 52 through the connecting rod 53 to block the spark particles generated during flame cutting. The baffle plate 52 can help limit the diffusion range of the spark particles and prevent them from splashing onto areas or equipment that do not require cutting, thereby reducing equipment damage or work area pollution caused by the splashing of spark particles.

When in use, the automatic cutting device is placed at a suitable position at the discharge port of the continuous casting machine. When the continuous casting billet is moved to the automatic cutting device, the clamp control device 9 is started through the operating device 7, and the clamp control device 9 will drive the two clamp bodies 11 to clamp the continuous casting billet. Then, the flame cutting device 71 is started through the operating device 7, and the flame cutting device 71 will cut the continuous casting billet. In this process, the movement of the continuous casting billet will drive the U-shaped beam 8 to move along through the clamp control device 9 and the two clamp bodies 11, and the U-shaped beam 8 drives the moving trolley 4 to move along the track plate 3. Before the two clamp bodies 11 clamp the continuous casting billet, the staff moves away from the main body of the device. The slide column 13 is pulled in the direction of the center of the body 1, and the spring corresponding to the slide column 13 is compressed. Then, after the continuous casting billet moves between the two U-shaped scrapers 15, the slide column 13 is released. Under the action of the spring force corresponding to the slide column 13, the slide column 13 drives the U-shaped scraper 15 to be close to the outer wall of the continuous casting billet, and the screw 12 is driven by the motor to rotate forward and reverse. The screw 12 drives the U-shaped slide bar 14 to move back and forth up and down along the inside of the circular groove frame 10. The U-shaped slide bar 14 drives the U-shaped scraper 15 and the triangular scraper 16 to move back and forth up and down through the slide column 13, so that the U-shaped scraper 15 and the triangular scraper 16 can scrape off the steel slag adhered to the side wall of the continuous casting billet, thereby cleaning the side wall of the continuous casting billet. The purpose is to avoid the problem that the steel slag will cause the side wall of the continuous casting billet clamped by the clamp body 11 to be uneven, making it impossible for the clamp body 11 to apply the clamping force evenly, affecting the stability and accuracy of the continuous casting billet cutting process; when the clamp body 11 clamps the continuous casting billet, the open side wall of the clamp body 11 will push the inclined surface of the triangular scraper 16 to drive the triangular scraper 16 to retract into the interior of the U-shaped scraper 15, and the spring between the two triangular scrapers 16 is compressed. After the triangular scraper 16 is retracted into the interior of the U-shaped scraper 15, the clamp body 11 can effectively clamp the side wall of the continuous casting billet; in the process of the triangular scraper 16 retracting into the interior of the U-shaped scraper 15, the triangular scraper 16 The semicircular block pushes the semi-arc block of the T-shaped rod 20 to drive the T-shaped rod 20 to move upward. When the semicircular block of the triangular scraper 16 no longer pushes the semi-arc block of the T-shaped rod 20, under the action of the spring force corresponding to the T-shaped rod 20, the T-shaped rod 20 resets and moves downward, and so on. The T-shaped rod 20 will intermittently push the middle part of the spring plate 19 to move upward. Since the positions on both sides of the spring plate 19 are restricted by the slider 18, the spring plate 19 will intermittently bulge and deform, so that the spring plate 19 pushes the slag falling on the surface of the U-shaped scraper 15 to the positions on both sides, thereby avoiding the problem of slag adhering to the surface of the U-shaped scraper 15 and affecting the efficiency of the U-shaped scraper 15 in scraping slag on the surface of the continuous casting billet.

When the flame cutting device 71 cuts the continuous casting billet, spark particles will be generated. The sleeve plate 51 drives the baffle 52 through the connecting rod 53 to block the spark particles generated during the flame cutting. The baffle 52 can help limit the diffusion range of the spark particles and prevent them from splashing onto areas or equipment that do not need to be cut, thereby reducing equipment damage or work area pollution caused by the splashing of spark particles; when the U-shaped beam 8 moves, the U-shaped beam 8 drives the resistance rod 54 to move along with it, and the semi-arc shape of the resistance rod 54 pushes the inclined surface of the triangular block 56 to drive the U-shaped slide plate 55 to move downward, and the U-shaped slide plate 55 drives the hinged rod 57 to drive the connecting rod 53 to move away from the center of the device body 1, and the connecting rod 53 drives the baffle 52 to move along with it, so that the baffle 52 scrapes off the slag adhered to the outer wall of the guide roller 2, thereby avoiding the presence of slag, causing the surface of the guide roller 2 to be uneven, resulting in the uneven height position of the continuous casting billet when the guide roller 2 transmits the continuous casting billet, affecting the cutting accuracy of the flame cutting device 71.

Please refer to Figures 1-7. Based on the above-mentioned embodiment, in another embodiment of the present invention, a U-shaped slide plate 55 is slidably installed on the top of the sleeve plate 51, and a plurality of triangular blocks 56 are fixed on the top of the U-shaped slide plate 55. A hinged rod 57 is hinged on the top of the side of the U-shaped slide plate 55 away from the center of the device body 1. The end of the hinged rod 57 away from the U-shaped slide plate 55 is hinged to the top of the side of the connecting rod 53 away from the center of the device body 1. Resistance rods 54 are fixed on both sides of the bottom of the U-shaped beam 8. The bottom of the resistance rod 54 is semi-arc-shaped. The inclined surface of the triangular block 56 is located on the semi-arc motion trajectory of the resistance rod 54. Through the arrangement of the above-mentioned structure, the baffle 52 scrapes off the slag adhered to the outer wall of the guide roller 2, thereby avoiding the presence of slag, causing the surface of the guide roller 2 to be uneven, resulting in the uneven height position of the continuous casting billet when the guide roller 2 transmits the continuous casting billet, affecting the cutting accuracy of the flame cutting device 71.

A positioning device 6 is provided on both sides of the circular groove frame 10, and the positioning device 6 includes a fixing rod 61 and a V-shaped groove plate 63. The fixing rod 61 is fixed to the side of the circular groove frame 10 away from the center of the device body 1, and an elastic telescopic rod 62 is fixed to the bottom of the fixing rod 61 away from the side of the circular groove frame 10, and the V-shaped groove plate 63 is fixed to the side of the track plate 3 away from the device body 1, and the V-shaped groove plate 63 is located at the cutting starting point of the flame cutting device 71. The bottom of the elastic telescopic rod 62 is arranged in a round block shape, and a V-shaped groove is opened on the top of the V-shaped groove plate 63. The V-shaped groove of the V-shaped groove plate 63 is used to accommodate the round block of the elastic telescopic rod 62. The top two sides of the V-groove plate 63 are provided with chamfers. Through the arrangement of the above structure, the U-shaped slide bar 14 drives the elastic telescopic rod 62 to move downward through the fixed rod 61, and the round block of the elastic telescopic rod 62 moves downward accordingly. The V-groove inclined surface of the V-groove plate 63 guides the position of the elastic telescopic rod 62 through the round block of the elastic telescopic rod 62, thereby forcing the elastic telescopic rod 62 to drive the flame cutting device 71 to move to the starting point of cutting through the fixed rod 61, the U-shaped slide bar 14 and the U-shaped beam 8, thereby helping to improve the accuracy of the flame cutting device 71 when flame cutting the next continuous casting billet.

When in use, after the cutting of a continuous casting billet is completed, the clamp control device 9 is started through the control device 7, and the clamp control device 9 will drive the two clamp bodies 11 to no longer clamp the continuous casting billet. At this time, the mobile trolley 4 is started, and the mobile trolley 4 will drive the flame cutting device 71 to move to the cutting starting point through the U-shaped beam 8 and the control device 7. In this process, the U-shaped beam 8 will drive the fixed rod 61 to move, and the fixed rod 61 will drive the elastic telescopic rod 62 to move. When the elastic telescopic rod 62 moves to the chamfered position of the V-shaped groove plate 63, the chamfered inclined surface of the V-shaped groove plate 63 pushes the round block of the elastic telescopic rod 62 to squeeze the telescopic end of the elastic telescopic rod 62 until the elastic telescopic rod 62 is moved. The round block shape of the retracted rod 62 passes over the chamfer of the V-groove plate 63 and enters the V-groove plate 63 part of the V-groove plate 63. Each time the U-shaped slide bar 14 moves downward, the U-shaped slide bar 14 drives the elastic telescopic rod 62 to move downward through the fixed rod 61, and the round block shape of the elastic telescopic rod 62 moves downward accordingly. The V-groove inclined surface of the V-groove plate 63 guides the position of the elastic telescopic rod 62 through the round block shape of the elastic telescopic rod 62, thereby forcing the elastic telescopic rod 62 to drive the flame cutting device 71 to move to the starting point of cutting through the fixed rod 61, the U-shaped slide bar 14 and the U-shaped beam 8, thereby helping to improve the accuracy of the flame cutting device 71 when flame cutting the next continuous casting billet.
