Description

Technical Field

[0001] This invention relates to the technical field of shearing machines, and in particular to a hydraulic shearing machine for continuous casting steel billets. Background Technology

[0002] Continuously cast (steel) billets are products obtained by casting molten steel produced in a steelmaking furnace through a continuous casting machine. Continuously cast steel billets come in cylindrical, square, and hollow cylindrical shapes. To meet the needs of different sizes and applications, hollow cylindrical steel billets require shearing machines.

[0003] In the prior art, patent application number 201921334123.3 discloses a shearing device for steel billets, including a workbench, with support plates fixedly installed on the left and right sides of the top of the workbench, the tops of the two support plates being fixedly connected to a top plate, a clamping plate fixedly installed on one side of the opposite face of the two support plates, and hydraulic telescopic rods that penetrate through and extend to the bottom of the top plate fixedly installed on the left and right sides of the top of the top plate.

[0004] Patent application number 201910377656.8 discloses a novel steel billet shearing device, comprising a worktable; a support column is provided on the top surface of the worktable; a support horizontal plate is provided at the top of the support column; a shearing hydraulic telescopic rod is fixedly provided on the support horizontal plate; the shearing piston rod of the shearing hydraulic telescopic rod vertically downwards through the support horizontal plate; an upper shearing blade is fixedly provided at the bottom end of the shearing piston rod; a cutting groove is provided on the top surface of the worktable below the upper shearing blade; a lower shearing blade is fixedly provided in the cutting groove; a first conveyor belt is provided on one side of the lower shearing blade; a second conveyor belt is provided on the other side of the lower shearing blade; a first auxiliary transmission mechanism is provided on one side of the worktable; and a second auxiliary transmission mechanism is provided on the other side of the worktable.

[0005] When the above-mentioned device is used to shear large-diameter hollow cylindrical steel billets, it needs to be used with a large hydraulic cylinder, which is expensive. The cross-section of the hollow cylindrical steel billet being sheared will undergo plastic deformation, which will destroy the neatness of the end face. In addition, the steel billet may be squeezed and deformed near the end face during the shearing process, which will increase the workload for subsequent processes. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a hydraulic shearing machine for continuously cast steel billets that improves the flatness of the cut surface.

[0007] This invention discloses a hydraulic shearing machine for continuously cast steel billets, comprising a base plate, a support assembly, and a cutting assembly. The support assembly and cutting assembly are located at the top of the base plate, with the cutting assembly positioned behind the support assembly. The machine also includes a feeding assembly and an ultrasonic vibration assembly, both located at the top of the base plate. The feeding assembly is positioned to the left of the support assembly. The feeding assembly is used to convey and rotate the steel billet, while the ultrasonic vibration assembly is used to enter the inner side of the steel billet and perform ultrasonic vibration inside. When shearing is required, the steel billet is placed on the feeding assembly, which moves the billet to the right, while the support assembly supports the portion of the billet to be sheared. After the support and adjustment are completed, the feeding assembly stops conveying the steel billet and starts rotating it. The billet rotates with the support assembly, and the ultrasonic vibration assembly is activated. The ultrasonic vibration assembly vibrates the inside of the billet, causing the part of the billet to be cut to vibrate. Then, the cutting assembly is activated and moves downwards, cutting the outer wall of the rotating billet, which is accompanied by internal ultrasonic vibration. The high-frequency magnetic vibration of the billet, combined with the ultrasonic waves, allows the cutting device to quickly cut the billet while ensuring a flat end face. This enables the use of a small cutting device to cut large-diameter billets, saving costs and improving processing efficiency.

[0008] Preferably, the ultrasonic vibration assembly includes a groove, a first electric track, a first movable seat, a column, a vertical plate, a support tube, a second electric track, a second movable seat, a bearing, a circular plate, a circular pad, an ultrasonic generator, and an ultrasonic transducer. The top of the base plate has two sets of grooves, each containing a set of first electric tracks. A first movable seat is slidably mounted on the two sets of first electric tracks. A column is mounted on the top of the first movable seat, and a vertical plate is mounted on the top of the column. The support tube passes through the vertical plate and is slidably connected to it. A second electric track is mounted on the top of the first movable seat, and the second electric track is mounted on the vertical plate. On the right side, a second movable seat is slidably mounted on the second electric track. A clamp is mounted at the top of the second movable seat, clamping the support tube. The left end of the support tube is rotatably connected to a circular plate via a bearing. A circular pad is mounted on the left end of the circular plate. An ultrasonic generator is mounted on the right end of the second movable seat. The ultrasonic transducer is mounted inside the left end of the support tube via a fixing frame. The output end of the ultrasonic transducer is rotatably connected to the right end of the circular plate via a rotary joint. The ultrasonic generator is electrically connected to the ultrasonic transducer via an electric wire passing through the inside of the support tube. The diameter of the circular pad is matched to the inner diameter of the steel billet. After the steel billet is placed... The first moving seat moves to the left with the cooperation of two sets of first-order electric rails, causing the circular pad to enter the interior of the steel billet. The outer wall of the circular pad contacts the inner wall of the steel billet. Depending on the processing requirements of different billet lengths, the operator moves the second moving seat to the left with the cooperation of the second electric rail, causing the support tube to slide to the left with the cooperation of the vertical plate. This further causes the circular pad to slide to the left inside the steel billet, achieving the cutting of steel billets of different lengths. When the steel billet rotates, the circular pad, with the cooperation of bearings, follows the circular plate and rotates adaptively with the steel billet. Simultaneously, the circular plate and the circular pad rotate at the same point. With the cooperation of the head, it rotates relative to the ultrasonic transducer. At the same time, the circular pad starts the ultrasonic generator. The ultrasonic generator causes the ultrasonic transducer to vibrate through the wire. The ultrasonic transducer drives the circular pad to vibrate ultrasonically through the rotary joint and the circular plate. When the circular pad vibrates ultrasonically, the outer wall of the circular pad contacts the inner wall of the steel billet, thereby causing the steel billet to vibrate ultrasonically. The cutting assembly performs circumferential cutting on the ultrasonically vibrating steel billet, which improves the cutting efficiency and also realizes the rapid shearing of large-diameter steel billets without increasing the hydraulic cylinder model, while also ensuring the flatness of the end face.

[0009] Preferably, the feeding assembly includes a material rack, a guide roller frame, guide rollers, a third electric track, a third movable seat, a vertical plate, a reinforcing rod, a first hydraulic cylinder, a clamping plate, an anti-slip mat, a housing, and an electric chuck. The material rack is located at the top of the base plate. Multiple sets of guide roller frames are located on the top left of the material rack, each set of guide roller frames having one set of guide rollers. A housing is located on the top left of the material rack, and an electric chuck is mounted on the housing. A drive motor is located inside the housing to drive the electric chuck. The disc rotates, and a No. 3 electric track is installed at the top of the material rack. This track runs between the guide roller frame and the housing. A No. 3 movable seat slides along this track, and two sets of upright plates are installed at the top of each movable seat. A reinforcing rod is installed between the two sets of upright plates. A No. 1 hydraulic cylinder is installed at the outer end of each of the two sets of upright plates. The moving ends of both sets of No. 1 hydraulic cylinders extend between the two sets of upright plates and are each fitted with a clamping plate. V-shaped openings are provided at the adjacent ends of the two clamping plates. Each component is equipped with anti-slip pads. In use, the steel billet is hoisted onto multiple sets of guide rollers, which work together to support the billet. The right end of the billet passes between two sets of vertical plates. The first set of hydraulic cylinders extends, causing the two sets of clamping plates to clamp the outer wall of the billet via the corresponding anti-slip pads. Then, the third moving seat moves to the right on the third electric track, causing the two sets of clamping plates to move the billet to the right with the help of the multiple guide rollers. The right end of the billet enters the housing and passes through the electric chuck to the support assembly. The first hydraulic cylinder retracts, and the third moving seat moves to the left, allowing the two sets of clamping plates to convey the billet to any length. After conveying, the first hydraulic cylinder retracts, and the electric chuck clamps the outer wall of the billet. The drive motor then rotates the electric chuck, further causing it to rotate with the help of the multiple guide rollers and the support assembly, thus achieving both positional conveying and rotation of the billet.

[0010] Preferably, the support assembly includes a support plate, guide roller shafts, and guide rollers. Two pairs of support plates are provided at the top of the base plate. Each pair of support plates is rotatably equipped with a set of guide roller shafts, and each set of guide roller shafts is equipped with a set of guide rollers. The two sets of guide rollers cooperate with each other to support the steel billet. At the same time, when the steel billet rotates, the two sets of guide rollers rotate adaptively with the steel billet to improve the stability of the steel billet during processing.

[0011] Preferably, the cutting assembly includes a support frame, a rotating shaft, a movable plate, a first sprocket, a second sprocket, a transmission assembly, a first bracket, a rotating shaft, a cutting blade, and a hydraulic adjustment assembly. A support frame is mounted at the top of the base plate, a rotating shaft is rotatably mounted on the support frame, a movable plate is mounted on the rotating shaft, a motor is mounted at the top of the movable plate, and a first sprocket is mounted at the output end of the motor. A first bracket is mounted at the bottom front of the movable plate, a rotating shaft is rotatably mounted on the first bracket, and a cutting blade and a second sprocket are mounted on the rotating shaft. The second sprocket and the first sprocket are driven by the transmission assembly. A hydraulic adjustment assembly is provided between the top front of the rotating shaft and the front top of the movable plate. The hydraulic adjustment component is used to adjust the height of the cutting blade. When the billet rotates, the ultrasonic transducer drives the circular pad to perform ultrasonic vibration inside the billet. The motor is started, which causes the first sprocket to drive the second sprocket to rotate rapidly through the transmission component. This further causes the rotating shaft to drive the cutting blade to rotate rapidly. By operating the hydraulic adjustment component, the movable plate swings downward with the cooperation of the rotating shaft. The rapidly rotating cutting blade contacts and cuts the outer wall of the rotating billet. Because the inside of the billet is subjected to ultrasonic vibration by the circular pad, the cutting blade quickly performs circumferential cutting on the billet, improving processing efficiency.

[0012] Preferably, it also includes round holes, threaded grooves, and bolts. The round plate has multiple sets of round holes circumferentially, and the round pad has multiple sets of threaded grooves circumferentially. The bolts pass through the round holes and are threadedly connected to the threaded grooves. By passing the bolts through the round holes and threading them to the threaded grooves, the round pads are installed on the round plate. When the cutting blade cuts the steel billet, the cutting blade may accidentally cut the round pads. When the outer wall of the round pad is damaged, the bolts can be unscrewed to replace the round pads, thus improving convenience.

[0013] Preferably, the hydraulic adjustment assembly includes a first shaft pin, a second shaft pin, and a hydraulic push rod. The first shaft pin is located at the top front end of the support frame, and the second shaft pin is located at the front top end of the movable plate. One end of the hydraulic push rod is hinged to the front end of the support frame via the first shaft pin, and the other end of the hydraulic push rod is hinged to the top end of the movable plate via the second shaft pin. The motor is started, causing the cutting blade to rotate rapidly. When the billet begins to rotate, the hydraulic push rod is extended, causing the movable plate to swing downwards under the cooperation of the first and second shaft pins, further bringing the cutting blade into contact with the outer wall of the billet for cutting. After cutting, the hydraulic push rod is shortened, causing the cutting blade to move away from the billet.

[0014] Preferably, it also includes baffles and bellows covers. Two sets of baffles are set at the top of the material rack, and the second electric track is between the two sets of baffles. The inner ends of the two sets of baffles are respectively connected to one end of the two sets of bellows covers, and the other ends of the two sets of bellows covers are respectively connected to the left and right ends of the third moving seat. The two sets of bellows covers cooperate to cover and seal the third electric track. When the billet is conveyed to the right, the third moving seat moves horizontally on the third electric track. When impurities fall from the outer wall of the billet onto the third electric track, it affects the service life of the third moving seat. The two sets of bellows covers cooperate to cover and seal the third electric track, reducing the amount of impurities falling onto the third electric track.

[0015] Preferably, it also includes an annular arc-shaped groove, and the outer wall of the circular pad is provided with an annular arc-shaped groove; the circular pad is provided with an annular arc-shaped groove, which reduces the possibility of the circular pad being accidentally cut when the cutting blade cuts the steel billet, and improves the service life of the circular pad. At the same time, the inner arc end of the annular arc-shaped groove can concentrate ultrasonic waves and improve the vibration effect.

[0016] Preferably, the transmission assembly includes a third sprocket, a second bracket, a rotating shaft, a first chain, a fourth sprocket, and a second chain. An opening is provided on the movable plate, and a second bracket is located at the bottom of the movable plate. A rotating shaft is rotatably mounted on the second bracket, and the third and fourth sprockets are respectively mounted on the rotating shaft. The first and third sprockets are driven by a first chain, which passes through the opening. The fourth sprocket is driven by the second sprocket. Starting the motor causes the first sprocket to drive the rotating shaft to rotate rapidly via the first chain, which in turn drives the fourth sprocket to rotate rapidly via the second chain, thus achieving rapid rotation of the cutting disc. The first, second, third, and fourth sprockets, as well as the first and second chains, are not located outside the movable plate, reducing the potential harm to surrounding people during rotation and improving safety while increasing cutting efficiency.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: When it is necessary to shear the steel billet, the steel billet is placed on the feeding assembly, which moves the steel billet to the right. At the same time, the support assembly supports the part of the steel billet to be sheared. After adjustment, the feeding assembly stops feeding the steel billet and starts rotating the steel billet. The steel billet rotates with the cooperation of the support assembly. The ultrasonic vibration assembly is started, and the ultrasonic vibration assembly performs ultrasonic vibration on the inner side of the steel billet, thereby vibrating the part of the steel billet to be cut. Then, the cutting assembly is started and moves downward, so that the cutting assembly cuts the outer wall of the rotating steel billet with internal ultrasonic vibration. The high-frequency magnetic vibration of the steel billet, combined with the ultrasonic waves, enables the cutting device to cut the steel billet quickly and with a flat end face. This realizes the shearing of large-diameter steel billets with a small cutting device, saving costs and improving processing efficiency. Attached Figure Description

The support frame 30 is provided at the top of the base plate 1. The rotating shaft 31 is rotatably mounted on the support frame 30. The movable plate 32 is provided on the rotating shaft 31. The top of the movable plate 32 is provided with a motor 33. The output end of the motor 33 is provided with a first sprocket 34. The bottom front end of the movable plate 32 is provided with a first bracket 37. The rotating shaft 38 is rotatably mounted on the first bracket 37. The cutting disc 39 and the second sprocket 35 are respectively mounted on the rotating shaft 38. The second sprocket 35 and the first sprocket 34 are driven by the transmission assembly. A hydraulic adjustment assembly is provided between the top front end of the rotating shaft 31 and the front top end of the movable plate 32. The hydraulic adjustment assembly is used to adjust the height of the cutting disc 39.In use, the billet 55 is hoisted onto multiple sets of guide rollers 17. The multiple sets of guide rollers 17 cooperate to support the billet 55. The right end of the billet 55 passes between two sets of vertical plates 20. The two sets of hydraulic cylinders 22 are extended, so that the two sets of clamping plates 23 clamp the outer wall of the billet 55 through the corresponding anti-slip pads 24. Then, the third moving seat 19 is moved to the right on the third electric track 18, so that the two sets of clamping plates 23, with the cooperation of the multiple sets of guide rollers 17, drive the billet 55 to the right. The right end of the billet 55 enters the housing 25 and passes through the electric chuck 26. The two sets of guide rollers 29 cooperate to support the billet 55. The first hydraulic cylinder 22 is shortened. The third moving seat 19 is moved to the left, so that the two sets of clamping plates... 23. For conveying steel billets 55 to any length, after the billet 55 is placed, the first moving seat 4 is moved to the left with the cooperation of two sets of first electric rails 3, so that the circular pad 12 enters the interior of the steel billet 55. The outer wall of the circular pad 12 contacts the inner wall of the steel billet 55. According to the processing requirements of different lengths of steel billets, the operator moves the second moving seat 9 to the left with the cooperation of the second electric rail 8, so that the support pipe 7 slides to the left with the cooperation of the vertical plate 6, further causing the circular pad 12 to slide to the left inside the steel billet 55. The first hydraulic cylinder 22 is shortened, and then the electric chuck 26 is operated to clamp the outer wall of the steel billet 55. Then the drive motor drives the electric chuck 26 to rotate, further causing the electric... The moving chuck 26, in cooperation with multiple sets of guide rollers 17 and support components, drives the billet 55 to rotate, achieving both positional conveying and rotation of the billet 55. Two sets of guide rollers 29 rotate adaptively with the billet 55. The circular pad 12, in cooperation with the bearing 10, rotates adaptively with the circular plate 11 and the billet 55. Simultaneously, the circular plate 11 and the circular pad 12, in cooperation with the rotary joint, rotate relative to the ultrasonic transducer 14. At the same time, the circular pad 12 activates the ultrasonic generator 13, which, through wires, causes the ultrasonic transducer 14 to vibrate. The ultrasonic transducer 14, through the rotary joint and the circular plate 11, drives the circular pad 12 to undergo ultrasonic vibration. During vibration, the outer wall of the circular pad 12 contacts the inner wall of the steel billet 55, causing the billet 55 to undergo ultrasonic vibration. Starting the motor 33 causes the first sprocket 34 to drive the second sprocket 35 to rotate rapidly via the transmission assembly. This further causes the rotating shaft 38 to drive the cutting blade 39 to rotate rapidly. Operating the hydraulic adjustment assembly causes the movable plate 32 to swing downwards in conjunction with the rotating shaft 31. The rapidly rotating cutting blade 39 contacts and cuts the outer wall of the rotating steel billet 55. Because the inner part of the steel billet 55 undergoes ultrasonic vibration due to the action of the circular pad 12, the cutting blade 39 performs rapid circumferential cutting on the steel billet 55. Alternatively, the motor 33 can be turned off, allowing the cutting blade 39 to perform rolling cutting on the steel billet. Example 2

An opening is provided on the movable plate 32, and a second bracket 50 is located at the bottom of the movable plate 32. A rotating shaft 51 is rotatably mounted on the second bracket 50. The third sprocket 49 and the fourth sprocket 53 are respectively mounted on the rotating shaft 51. The first sprocket 34 and the third sprocket 49 are driven by the first chain 52, which passes through the opening. The fourth sprocket 53 and the second sprocket 35 are driven by the second chain 54. In use, the billet 55 is hoisted onto multiple sets of guide rollers 17. The multiple sets of guide rollers 17 cooperate to support the billet 55. The right end of the billet 55 passes between two sets of vertical plates 20. The two sets of first sprockets are operated... Hydraulic cylinder 22 extends, causing the two sets of clamping plates 23 to clamp the outer wall of the billet 55 through the corresponding anti-slip pads 24. Then, the third moving seat 19 is operated to move to the right on the third electric track 18. The two sets of bellows covers 47 cooperate to cover and seal the third electric track 18, reducing the amount of impurities falling onto the third electric track 18. This causes the two sets of clamping plates 23 to move the billet 55 to the right with the cooperation of multiple sets of guide rollers 17. The right end of the billet 55 enters the housing 25 and passes through the electric chuck 26. The two sets of guide rollers 29 cooperate to support the billet 55. Hydraulic cylinder 22 shortens, and the third moving seat 19 is operated to move to the left, realizing the conveying of the billet 55 to any length by the two sets of clamping plates 23. After the billet 55 is placed, the first moving seat 19 is operated to move to the left. The seat 4 moves to the left with the cooperation of two sets of No. 1 electric rails 3, so that the circular pad 12 enters the interior of the billet 55. The outer wall of the circular pad 12 contacts the inner wall of the billet 55. According to the processing requirements of different lengths of the billet, the operator moves the No. 2 moving seat 9 to the left with the cooperation of the No. 2 electric rail 8, so that the support tube 7 slides to the left with the cooperation of the vertical plate 6, further causing the circular pad 12 to slide to the left inside the billet 55. The No. 1 hydraulic cylinder 22 is shortened, and then the electric chuck 26 is operated to clamp the outer wall of the billet 55. Then the drive motor drives the electric chuck 26 to rotate, and the electric chuck 26 drives the billet 55 to rotate with the cooperation of multiple sets of guide rollers 17 and support components, so as to realize the positioning of the billet 55. While the billet 55 is being conveyed, it rotates. Two sets of guide rollers 29 rotate adaptively with the billet 55. The circular pad 12, with the cooperation of the bearing 10, rotates adaptively with the circular plate 11 and the billet 55. Simultaneously, the circular plate 11 and the circular pad 12 rotate relative to the ultrasonic transducer 14 with the cooperation of the rotary joint. At the same time, the circular pad 12 activates the ultrasonic generator 13. The ultrasonic generator 13 causes the ultrasonic transducer 14 to vibrate via wires. The ultrasonic transducer 14 drives the circular pad 12 to vibrate ultrasonically through the rotary joint and the circular plate 11. When the circular pad 12 vibrates ultrasonically, its outer wall contacts the inner wall of the billet 55, causing the billet 55 to vibrate ultrasonically. The motor 33 is then activated.This causes the first sprocket 34 to drive the rotating shaft 51 to rotate rapidly via the first chain 52, which in turn causes the fourth sprocket 53 to drive the second sprocket 35 to rotate rapidly via the second chain 54, thus achieving rapid rotation of the cutting blade 39. The hydraulic push rod 45 extends, causing the movable plate 32 to swing downwards under the cooperation of the first and second shaft pins 43 and 44. The rapidly rotating cutting blade 39 contacts and cuts the outer wall of the rotating steel billet 55. Due to the ultrasonic vibration of the circular pad 12 at the cutting point of the steel billet 55, the cutting blade 39 rapidly performs a circumferential cut on the steel billet 55. When the cutting blade 39 cuts the steel billet 55, it may accidentally cut the circular pad 12. If the outer wall of the circular pad 12 is damaged, the bolt 42 can be loosened to replace the circular pad 12. Alternatively, the motor 33 can be turned off, allowing the cutting blade 39 to perform a rolling cut on the steel billet. The cutting blade 39 can be either a cutting blade or a rolling cutter.
