Description

Technical Field

[0001] This invention relates to the field of metal rolling technology, and in particular to a component for improving the bending of the tail end of a flying shear. Background Technology

[0002] Components that improve the bending of the shear tail during flying shearing play multiple roles in steel rolling production lines, directly impacting production efficiency and product quality. By optimizing the shape and angle of the shear blade, as well as adjusting the timing and position of the flying shear, shearing accuracy can be significantly improved. This helps reduce deformation and errors in the rolled piece during the shearing process, ensuring that the dimensions and shape of the sheared piece meet standard requirements.

[0003] Existing components for improving tail bending during flying shear cutting include a horizontally positioned trough bottom plate and a movable flap at the end. By adjusting the angle between the movable flap and the trough bottom plate, the rolled piece can smoothly enter the trough after shearing, reducing tail bending. However, when the movable flap needs to be replaced and maintained after long-term use, it requires workers to use special tools and have certain professional skills to disassemble it. This increases the workload of workers and reduces the efficiency of replacing and maintaining the movable flap. Summary of the Invention

This component can solve the problem that when the movable flap needs to be replaced and maintained after long-term use, it requires workers to use special tools and have certain professional skills to disassemble it, which increases the workload of workers and reduces the efficiency of replacing and maintaining the movable flap.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a component for improving the bending of the tail end of a flying shear, comprising a trough bottom plate, wherein a limit device is provided at one end of the trough bottom plate;

[0006] The limiting device includes a movable flap and two fixed sliders. Fixed slider grooves are provided on both sides of the inner wall of the groove at one end of the running track bottom plate.

[0035] Please see Figure 1-5 The present invention provides a technical solution: a component for improving the bending of the tail end of a flying shear, including a trough bottom plate 10;

[0036] A limit device is provided at one end of the bottom plate 10 of the running track;

[0037] The limiting device includes a movable flap 8 and two fixed sliders 5. Fixed slider grooves 7 are provided on both sides of the inner wall of the groove at one end of the running track bottom plate 10. The outer walls of the fixed rod at one end of the movable flap 8 are slidably connected to the interior of the corresponding fixed slider grooves 7. Guide grooves 23 are provided inside the interior of each of the two fixed slider grooves 7. The outer walls of the two fixed sliders 5 are slidably connected to the interior of the corresponding fixed slider grooves 7. A fixed block 19 is fixedly connected to the lower surface of the movable flap 8. The outer walls of the two fixed sliders 5 near the running track bottom plate 10 are arc-shaped. The outer walls of the fixed rod at one end of the movable flap 8 are rotatably connected to the inner wall of the arc-shaped groove at one end of the outer wall of the corresponding fixed slider 5. Fixed bolts 6 are threadedly connected to the outer walls of the two fixed sliders 5. Fixed bolt grooves 20 are provided on both sides of the outer walls of the running track bottom plate 10 near the movable flap 8. The ends of the two fixed bolts 6 near the fixed bolt grooves 20 extend threadedly into the interior of the fixed bolt grooves 20. The outer walls of the guide blocks at the upper ends of the two fixed sliders 5 are slidably connected to the interior of the corresponding guide grooves 23.

[0038] The bottom outer wall of the trough base plate 10 is fixedly connected to a mounting base 14. A limit rod 21 is slidably connected inside the fixing block 19. A limit bolt 22 is threadedly connected inside the threaded groove of one end of the limit rod 21. A feed box 12 is bolted to the end of the trough base plate 10 away from the movable flap 8. A base 1 is provided on the outside of the trough base plate 10. A fixing seat 2 is bolted to the upper surface of the base 1. Cylinders 13 are installed inside both sides of the fixing seat 2. A fixing support column 15 is fixedly connected to the lower surface of the bottom of the trough base plate 10. A first movable block 16 is rotatably connected to the outer wall of the fixing support column 15. A hydraulic telescopic rod 17 is fixedly connected to the outer wall of the first movable block 16 away from the fixing support column 15. Two cylinders The output ends of 13 are all fixedly connected to sliding plates 11. The outer walls of the two sliding plates 11 are slidably connected to the inside of the grooves on both sides of the fixed seat 2. The lower surface of the mounting seat 14 is fixedly connected to the upper surface of the two sliding plates 11. The output end of the hydraulic telescopic rod 17 is fixedly connected to the second movable block 18. The two sides of the second movable block 18 away from the hydraulic telescopic rod 17 are rotatably connected to the outer walls on both sides of the limit rod 21. The lower end of the bottom plate 10 is fixedly connected to the outer wall of a fixed plate 3. The upper surface of the fixed plate 3 is fixedly connected to a motor 4. The inner wall of the groove of the bottom plate 10 is rotatably connected to a roller 9. The output end of the motor 4 extends rotatably into the groove of the bottom plate 10 and is fixedly connected to one end of the roller 9.

[0039] Furthermore, when using this device, it is started by connecting to an external power source. First, the equipment is installed in the designated position via the base 1. Then, the output end of the cylinder 13 drives the sliding plate 11 to move upward, simultaneously moving the mounting base 14 upward. Next, the mounting base 14 moves upward, causing the trough bottom plate 10 to move upward to adjust the height. Then, the rolled material enters the interior of the trough bottom plate 10 through the feed box 12. Then, the output end of the motor 4 drives the idler roller 9 to rotate, while the idler roller 9 provides auxiliary conveying of the rolled material. Next, before the rolled material reaches the flying shear, the movable flap 8 should be in a low position. Then, after the head of the rolled piece passes the trough bottom plate 10 and before the flying shear section, the output end of the hydraulic telescopic rod 17 drives the second movable block 18 to move upward. When the second movable block 18 cooperates with the fixed block 19, the movable flap 8 is adjusted to a horizontal position. At this time, after the multiple-length segmented shearing, the tail end impacts the inner bottom plate of the running groove bottom plate 10. However, since the movable flap 8 is in a horizontal position, this will reduce the bending of the steel at the tail end of the rolled piece. Then, when it is necessary to remove the movable flap 8, the fixed bolt 6 is turned to rotate so that its other end is disengaged from the inside of the fixed bolt groove 20. Then, the fixed slider 5 is removed from the inside of the fixed slider groove 7. Then, the limit bolt 22 is turned to rotate so that it is disengaged from the inside of the threaded groove of one end of the limit rod 21. Then, the limit rod 21 is removed from the fixed block 19, thereby disengaging the second movable block 18 from the fixed block 19. Then, the movable flap 8 can be removed from the running groove bottom plate 10 by pulling it.

[0040] By rotating the fixing bolt 6 in the limiting device to disengage its other end from the inside of the fixing bolt groove 20, the fixing slider 5 is removed from the inside of the fixing slider groove 7. Then, the limiting bolt 22 is rotated to disengage from the threaded groove at one end of the limiting rod 21. The limiting rod 21 is then removed from the fixing block 19, thereby disengaging the second movable block 18 from the fixing block 19. Finally, the movable flap 8 is pulled to remove it from the bottom plate 10 of the running trough. This disassembly of the movable flap 8 is simple and quick, effectively improving the work efficiency of the staff and the efficiency of replacing and maintaining the movable flap 8. When the rolled material has not yet reached the flying shear, the movable flap 8 should be in a low position. Then, when the head of the rolled material passes the bottom plate 10 of the running trough and before the flying shear section, the movable flap 8... The output end of the hydraulic telescopic rod 17 drives the second movable block 18 to move upward, and at the same time, the second movable block 18 cooperates with the fixed block 19 to adjust the movable flap 8 to a horizontal position. At this time, the tail of the multiple-length segmented shear impacts the inner bottom plate of the running groove bottom plate 10. However, due to the horizontal position of the movable flap 8, the bending of the steel at the tail of the rolled piece is reduced, which effectively improves the quality of the flying shear and enhances the practicality of the equipment. The output end of the cylinder 13 drives the sliding plate 11 to move upward, which in turn drives the mounting base 14 to move upward. Then, the mounting base 14 moves upward, which drives the running groove bottom plate 10 to move upward to adjust the height. This makes it easier for the operator to adjust the height of the running groove bottom plate 10, effectively improving the flexibility of the equipment and the work efficiency of the operator.

[0041] Working principle: First, the equipment is installed in the designated position via the base 1. Then, the output end of the cylinder 13 drives the sliding plate 11 to move upward, simultaneously moving the mounting base 14 upward. Next, the mounting base 14 moves upward, causing the trough bottom plate 10 to move upward for height adjustment. Then, the rolled material enters the interior of the trough bottom plate 10 through the feed box 12. Then, the output end of the motor 4 drives the idler roller 9 to rotate, while the idler roller 9 provides auxiliary conveying of the rolled material. Next, before the rolled material reaches the flying shear, the movable flap 8 should be in a low position. Then, when the head of the rolled piece passes the trough bottom plate 10 and the flying shear section, the output end of the hydraulic telescopic rod 17 drives the second movable block 18 to move upward, while the second movable block 1... 8 cooperates with the fixed block 19 to adjust the movable flap 8 to a horizontal position. At this time, after the multiple-length segmented shearing, the tail end impacts the inner bottom plate of the running groove bottom plate 10. However, due to the horizontal position of the movable flap 8, this will reduce the bending of the steel at the tail of the rolled piece. Then, when it is necessary to remove the movable flap 8, turn the fixed bolt 6 to rotate so that its other end is disengaged from the inside of the fixed bolt groove 20. Then, remove the fixed slider 5 from the inside of the fixed slider groove 7. Then, turn the limit bolt 22 to rotate so that it is disengaged from the inside of the thread groove at one end of the limit rod 21. Then, remove the limit rod 21 from the fixed block 19, thereby disengaging the second movable block 18 from the fixed block 19. Then, pull the movable flap 8 to remove the movable flap 8 from the running groove bottom plate 10.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
