Description

Technical Field

[0001] This utility model relates to a device for cutting and separating continuous casting billets, belonging to the technical field of continuous casting equipment. Background Technology

[0002] In continuous casting production, billets are cut into different lengths using a flame cutting machine according to production specifications. However, during the cutting process, problems often arise due to equipment and human error, resulting in incomplete cuts and "sticky cuts," which require further cutting. Currently, the common methods are to use an overhead crane to lift the billet and twist it off on the conveyor rollers, or to directly lower it off the conveyor rollers for processing. Twisting it off on the conveyor rollers can damage the roller equipment, while lowering it off the conveyor rollers is time-consuming and affects subsequent production processes. Therefore, it is essential to solve the problem of cutting and separating the sticky cuts from the continuous casting billet. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rapid cutting and separation device for continuous casting billets with connecting blades. This cutting and separation device can cut and separate the continuous casting billets with connecting blades without the need for cranes or other equipment, and will not damage the conveyor rollers. The cutting and separation process is fast and labor-saving, which greatly improves work efficiency and ensures the normal production of subsequent processes.

[0004] The technical solution to the above technical problem is: A rapid cutting and separating device for continuous casting billets includes a conveyor roller table and conveyor rollers. The conveyor rollers are mounted on the conveyor roller table, and the continuous casting billet is placed on the conveyor rollers. It also includes a shearing fixed roller, a fixed roller base, a shearing lifting roller, a support arm, a fixed guide sleeve, and a lifting roller pushing mechanism. The fixed roller base is a cuboid plate, and two fixed roller bases are vertically fixed to both sides of the conveyor roller table. The roller shafts at both ends of the shearing fixed roller are mounted on the upper ends of the two fixed roller bases. The distance between the lower circumferential surface of the shearing fixed roller and the roller surface of the conveyor roller table matches the thickness of the continuous casting billet. The continuous casting billet passes through the gap between the shearing fixed roller and the conveyor roller, and the connecting part of the continuous casting billet is located on the shearing fixed roller. In front of the shearing lifting roller, the shearing lifting roller is located below the continuous casting billet in front of the shearing fixed roller. The continuous casting billet's connecting blade is located between the shearing fixed roller and the shearing lifting roller. The roller shafts at both ends of the shearing lifting roller are connected to the upper ends of the support arms. The fixed guide sleeves are cuboids, with two fixed guide sleeves located below the support arms. One end of each fixed guide sleeve is fixed to the side wall of the pit below the conveyor roller track. Each fixed guide sleeve has a vertical guide hole. The lower parts of the two support arms pass through the guide holes of the two fixed guide sleeves, and the support arms and guide holes are in a sliding fit. The lower ends of the two support arms are connected to the upper ends of the lifting roller pushing mechanism, and the lower ends of the lifting roller pushing mechanism are fixed to the bottom of the pit below the conveyor roller track.

[0005] In the aforementioned rapid cutting and separation device for continuous casting billet cutters, the multiple conveying rollers of the conveying roller track behind the shearing fixed roller are pressure-reinforced rollers. The diameter of the pressure-reinforced rollers is larger than the diameter of the conveying rollers of the conveying roller track, and the upper surface of the pressure-reinforced rollers is on the same horizontal plane as the upper surface of the conveying rollers of the conveying roller track.

[0006] In the aforementioned rapid cutting and separation device for continuous casting billet cutters, bearings are respectively installed on the two ends of the shearing fixed roller and the shearing lifting roller. The two ends of the shearing fixed roller and the shearing lifting roller are rotatably connected to the upper ends of the two fixed roller bases and the upper ends of the two support arms through the bearings.

[0007] The aforementioned rapid cutting and separation device for continuous casting billet cutters comprises an upper connecting rod, a lower crank rod, an upper pull rod, a lower pull rod, a support base, a hydraulic cylinder, and cylindrical pins. The upper connecting rod is a cuboid with pin holes at its upper and lower ends. The upper pin holes of the two upper connecting rods are rotatably connected to the lower pin holes of the two support arms via cylindrical pins. The lower crank rod is an L-shaped rod with pin holes at its upper, lower, and L-shaped bend points. The upper and lower pull rods are both long rods with pin holes at both ends of the upper pull rod and the lower pin holes of the two upper connecting rods are respectively connected to the lower pin holes of the two support arms. The two lower cranks are rotatably connected to the upper pin holes of the two lower cranks and the pin holes at both ends of the upper pull rod via cylindrical pins. One end of the pull rod is connected to the front end of the piston push rod of the hydraulic cylinder. The two ends of the pull rod have pin holes. The lower pin holes of the two lower cranks are rotatably connected to the pin holes at both ends of the pull rod via cylindrical pins. The support base is a column. The upper ends of the two support bases have pin holes. The pin holes at the L-shaped bends of the two lower cranks are rotatably connected to the pin holes at the upper ends of the two support bases via cylindrical pins. The lower ends of the two support bases are fixed to the bottom surface of the pit below the conveyor roller conveyor.

[0008] The beneficial effects of this utility model are: The shearing fixing roller of this invention is located above the continuously cast billet to fix it. When shearing the continuous casting billet at the connecting blade, the shearing fixing roller can press the continuous casting billet to prevent the rear of the billet from lifting, so as to cooperate with the shearing lifting roller to shear the continuous casting billet. The shearing lifting roller is located below the front end of the continuous casting billet at the connecting blade position. When the shearing lifting roller rises, it can push the front of the continuous casting billet upward, so that the continuous casting billet is sheared and separated from the connecting blade. The pressure-bearing reinforcing roller at the rear of the continuous casting billet can bear the downward pressure of the rear of the continuous casting billet. The support arm can drive the shearing lifting roller to slide in the guide hole of the fixed guide sleeve. The lower end of the support arm is connected to the shearing pushing mechanism. The shearing pushing mechanism pushes the shearing lifting roller to rise through the support arm to shear and separate the continuous casting billet from the connecting blade. The piston rod of the hydraulic cylinder of the shearing pushing mechanism drives the support arm to move upward through the pull rod, lower crank rod, upper pull rod, and upper connecting rod to shear and separate the continuous casting billet.

[0009] This utility model has a simple structure and is easy to operate. It can shear and separate the continuous casting billet from the continuous casting blade on the conveyor roller, effectively reducing the abnormal unloading of the continuous casting billet, significantly improving production efficiency, reducing the risk of damage to the conveyor roller and other equipment during the hoisting of the continuous casting billet, increasing the temperature of the continuous casting billet, and reducing the energy consumption of subsequent rolling processes. It has the advantages of low investment, minimal modification to existing equipment, and low maintenance costs, and has significant economic benefits. Attached Figure Description

[0014] Figure 1 , 2 As shown, in order to shear and separate the connecting blade section 4 of the continuous casting billet 3 on the conveyor roller 1, shearing fixed roller 5 and shearing lifting roller 8 are installed on the conveyor roller 2 respectively. The shearing fixed roller 5 is used to press the rear part of the connecting blade section 4 of the continuous casting billet 3 to prevent the continuous casting billet 3 at the rear of the connecting blade section 4 from lifting upward. The shearing lifting roller 8 is used to push the front part of the connecting blade section 4 of the continuous casting billet 3 upward, so that the connecting blade section 4 breaks off, thus completing the shearing and separation of the connecting blade section 4.

[0015] Figure 1 , 2The shearing fixed roller 5 has its two end shafts mounted on the upper ends of two fixed roller bases 6 via bearings 12. The fixed roller bases 6 are rectangular plates, and the two fixed roller bases 6 are vertically fixed to both sides of the conveying roller track 1.

The shearing fixed roller 5 fixes the continuous casting billet 3. When shearing the connecting blade 4 of the continuous casting billet 3, the shearing fixed roller 5 can press the continuous casting billet 3 tightly to prevent the rear of the continuous casting billet 3 from lifting, thus cooperating with the shearing lifting roller 8 to shear the continuous casting billet 3.

The connecting part 4 of the continuous casting billet 3 is between the shearing fixed roller 5 and the shearing lifting roller 8. When the shearing lifting roller 8 lifts the front part of the continuous casting billet 3 upward, the continuous casting billet 3 will break at the connecting part 4.

The fixed guide sleeves 10 are cuboids, with two fixed guide sleeves 10 located below the support arms 9. One end of each fixed guide sleeve 9 is fixed to the side wall of the pit 20 below the conveyor roller table 1. Each fixed guide sleeve 9 has a vertical guide hole, through which the lower parts of the two support arms 9 pass, with a sliding fit between the support arms 9 and the guide holes. The lower ends of the two support arms 9 are connected to the upper ends of the lifting roller pushing mechanism 11, whose lower end is fixed to the bottom of the pit 20 below the conveyor roller table 1. The lifting pushing mechanism 11 uses the support arms 9 to lift the shearing lifting roller 8 upwards to shear the continuously cast billet 3.

[0018] Figure 1 , 2 As shown, the multiple conveyor rollers 2 of the conveyor roller table 1 behind the shearing fixed roller 5 are pressure-reinforced rollers 7. The diameter of the pressure-reinforced rollers 7 is larger than the diameter of the conveyor rollers 2 of the conveyor roller table 1, and the upper surface of the pressure-reinforced rollers 7 is on the same horizontal plane as the upper surface of the conveyor rollers 2 of the conveyor roller table 1. The pressure-reinforced rollers 7 can withstand the downward pressure generated by the lever action at the rear of the continuous casting billet 3 when shearing it.

[0019] Figure 3The lifting roller pushing mechanism 11 consists of an upper connecting rod 13, a lower crank rod 14, an upper pull rod 15, a lower pull rod 16, a support base 17, a hydraulic cylinder 18, and cylindrical pins 19. The upper connecting rod 13 is a cuboid, with pin holes at its upper and lower ends. The upper pin holes of the two upper connecting rods 13 are rotatably connected to the lower pin holes of the two support arms 9 via cylindrical pins 19. The lower crank rod 14 is an L-shaped rod, with pin holes at its upper, lower, and L-shaped bend points. The upper pull rod 15 and lower pull rod 16 are both long rods. The upper pull rod 15 has pin holes at both ends. The lower pin holes of the two upper connecting rods 13 are rotatably connected to the upper pin holes of the two lower crank rods 14 and the pin holes at both ends of the upper pull rod 15 via cylindrical pins 19, forming a single unit. One end of the pull rod 16 is connected to the front end of the piston rod of the hydraulic cylinder 18. The pull rod 16 has pin holes at both ends. The pin holes at the lower ends of the two lower crank rods 14 are rotatably connected to the pin holes at both ends of the pull rod 16 via cylindrical pins 19. The support base 17 is a column. The upper ends of the two support bases 17 have pin holes. The pin holes at the L-shaped bends of the two lower crank rods 14 are rotatably connected to the pin holes at the upper ends of the two support bases 17 via cylindrical pins 19. The lower ends of the two support bases 17 are fixed to the bottom surface of the pit 20 below the conveyor roller conveyor 1.

[0020] The lifting and pushing mechanism 11 of this utility model can also use two hydraulic jacks. The two hydraulic jacks are placed vertically in the pit 20. The push rod of the hydraulic jack is connected to the lower end of the support arm 9. When it is necessary to lift the shearing lifting roller 8, the hydraulic jacks are activated to lift the support arm 9 upward.

[0021] The working process of this utility model is as follows: The continuous casting billet 3 with the connecting blade is conveyed to the bottom of the shearing fixed roller 5 by the conveying roller 2. The connecting blade part 4 of the continuous casting billet 3 is located between the shearing lifting roller 8 and the shearing fixed roller 5, and the plane where the connecting blade part 4 of the continuous casting billet 3 is located does not intersect or tangent to the roller surface of the shearing lifting roller 8. The piston rod of the hydraulic cylinder 18 pushes forward, the hydraulic cylinder 18 drives the lower crank 14 to move, the lower crank 14 drives the connecting rod 13 to move, the connecting rod 13 drives the support arm 9 to move upward in the guide hole of the fixed guide sleeve 10, the support arm 9 drives the shearing lifting roller 8 to move upward, so that the continuous casting billet 3 above the shearing lifting roller 8 moves upward, and a shearing force is generated between the shearing lifting roller 8 and the shearing fixed roller 5 to cut the continuous casting billet 3 of the continuous cutter; After the continuous casting billet 3 is cut off at the connecting blade 4, the hydraulic cylinder 18 is driven to retract backward. The hydraulic cylinder 18 drives the lower crank 14, connecting rod 13, and support arm 9 to move in sequence. The support arm 9 drives the shearing lifting roller 8 to move downward, causing the continuous casting billet 3 above the shearing lifting roller 8 to move downward. The broken continuous casting billet 3 falls back onto the conveying roller 2, completing the connecting blade processing.
