[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] This invention provides, for example Figures 1-4 The image shows a hot-rolled coil shearing device.
[0020] Example 1: Includes a base 1, a cutter 9, a sliding plate 13, and a positioning mechanism. The cutter 9 is rotatably mounted above the base 1 and is used to shear hot-rolled coils. The sliding plate 13 is slidably mounted above the base 1 and has a lifting mechanism inside that can compress the hot-rolled coils. The positioning mechanism is located above the base 1 and is used to position and correct the hot-rolled coils. The cutter 9 consists of a rotating roller and multiple blades, which are horizontally spaced. A conveyor roller 10 is rotatably connected to the inner wall of a fixed plate 2. A driving component 8 is located outside the fixed plate 2 and is used to drive the conveyor roller 10 to rotate. There are two support plates 7 arranged horizontally and symmetrically. A guide plate 22 is attached to the conveyor roller 10. The conveyor roller 10 has multiple deep grooves inside, which can cooperate with the blades. The cutter 9 can be embedded deep into the conveyor roller 10. Inside the groove, to prevent the conveyor roller 10 from blocking the cutter 9, the cutter plate and the deep groove of the conveyor roller 10 are matched to reduce shearing resistance and improve efficiency. The conveyor roller 10 is used to convey the hot-rolled coil. The drive component 8 includes a servo motor and a protective shell. The protective shell is used to protect the servo motor, and a door is provided on the outside of the protective shell for easy maintenance by workers. The servo motor drives the conveyor roller 10 to rotate, and cooperates with the cutter 9 to cut the hot-rolled coil into multiple segments. The base 1 is set on one side of the output port of the hot-rolled coil conveying mechanism to realize the automated conveying of the hot-rolled coil. In specific use: the cutter 9 is used to cut the hot-rolled coil. After the hot-rolled coil is cut, the lifting mechanism is used to lift the hot-rolled coil. The positioning mechanism is used to prevent the hot-rolled coil from tilting or colliding, to ensure the flatness of the cut, to obtain a vertical and perfect cut surface, and to prevent damage to the tail of the hot-rolled coil.
[0021] In one aspect, the lifting mechanism includes a lifting structure and a compression structure. The lifting structure includes a roller 14 and a fixed plate 2. The roller 14 is rotatably connected to the inner wall of the sliding plate 13. The fixed plate 2 is fixedly connected to the outside of the base 1. A fixed block 15 is fixedly connected to the outer wall of the fixed plate 2, and a guide plate 22 is fixedly connected to the outer wall of the fixed block 15. The compression structure includes a lifting plate 18 and a rotating plate 23. The lifting plate 18 is slidably connected to the inner wall of the sliding plate 13. A rotating shaft 19 is rotatably connected to the inner wall of the lifting plate 18. The rotating plate 23 is fixedly sleeved on the outer wall of the rotating shaft 19. A compression roller 24 is rotatably connected to the outer wall of the rotating plate 23. A torsion spring 20 is fixedly connected between the rotating plate 23 and the sliding plate 13. A lifting drive assembly is provided on the outside of the lifting plate 18. The lifting drive assembly includes... Bolt 17 and circular rod 25 are used. Bolt 17 is threaded to the inner wall of sliding plate 13 and rotatably connected to the outer wall of lifting plate 18. Circular rod 25 is fixedly connected to the outer wall of lifting plate 18 and slidably connected to the inner wall of sliding plate 13. A slider 16 is fixedly connected to the outer wall of sliding plate 13. A fixing box 3 is fixedly connected to the outer wall of fixing plate 2. A first screw 4 is rotatably connected to the inner wall of fixing box 3. Slider 16 is threaded onto the outer wall of the first screw 4. A first handle 5 is fixedly connected to the outer wall of the first screw 4. Roller 14 is used to prevent the hot-rolled coil from falling and shifting after being sheared. Guide plate 22 is set as an inclined plate and is in contact with conveying roller 10 and roller 14. Guide plate 22 is used to make conveying roller 10 carry the cut hot-rolled coil. The hot-rolled coil is automatically conveyed to the outside of the roller 14. At this time, a certain gap is left between the extrusion roller 24 and the roller 14 to prevent the extrusion roller 24 from blocking the hot-rolled coil. The inner wall of the sliding plate 13 is provided with a groove, and the lifting plate 18 can slide up and down along the groove. The circular rod 25 is used to improve the stability of the lifting plate 18. When the hot-rolled coil is conveyed to the outside of the roller 14, the extrusion roller 24 and the roller 14 support the hot-rolled coil. The inner wall of the sliding plate 13 is provided with a threaded groove that matches the thread on the outer wall of the bolt 17. The rotation of the bolt 17 drives the lifting plate 18 to move. The lifting plate 18 can only move horizontally under the limitation of the circular rod 25. When the lifting plate 18 moves towards the roller 14, the roller 14 and the extrusion roller 24 come into contact. The thickness of the hot-rolled coil is adjusted according to the cutting requirements. The position of the adjustable rotating bolt 17 is adjusted so that the roller 14 and the extrusion roller 24 can be adapted to hot-rolled coils of different thicknesses, avoiding excessive tightness that could lead to deformation. The lifting plate 18 continues to move, and the extrusion roller 24 twists the torsion spring 20 through the rotating plate 23. The torsion spring 20 is used to clamp the hot-rolled coil between the extrusion roller 24 and the roller 14, positioning the hot-rolled coil and preventing it from shifting. The slider 16 is slidably disposed inside the fixed box 3. The fixed box 3 protects the first screw 4 and supports the slider 16, improving the stability of the slider 16's movement and preventing the first screw 4 from being worn or impacted by external objects. At the same time, the slider 16 drives the sliding plate 13 to move away from the conveying roller 10, so that the roller 14 and the conveying roller 10 cooperate to prevent the hot-rolled coil from falling.
[0022] Example 2: Example 2 further discloses a positioning mechanism based on Example 1, comprising a support box 11 and a positioning cylinder 21. The support box 11 is fixedly connected to the outer wall of the fixed plate 2, and a support plate 7 is slidably connected to the inner wall of the support box 11. The positioning cylinder 21 is rotatably connected to the inner wall of the support plate 7. A horizontal adjustment assembly is provided on the outside of the support plate 7, comprising a second screw 12 and a second handle 6. The second screw 12 is rotatably connected to the inner wall of the support box 11, and the support plate 7 is threadedly sleeved onto the outer wall of the second screw 12. The second handle 6 is fixedly connected to the outer wall of the second screw 12. The support plate 7 is used to support the positioning cylinder 21. The positioning cylinders 21 on both sides press and position the hot-rolled coil, centering and correcting the hot-rolled coil. The second screw 12 is set as a bidirectional screw, which drives the two support plates 7 to move away from or closer to each other. The support plates 7 are located in the support box 11. Under the limit of 1, it can only move horizontally. The support box 11 can prevent the second screw 12 from being damaged by external force collision. In daily use, the worker can regularly check and clean the second screw 12 with a brush to prevent the second screw 12 from being attached to the outside of the second screw 12, which would cause excessive wear of the second screw 12. The support plate 7 is fixedly covered with a protective pad to prevent the positioning cylinder 21 from rigidly colliding with the two sides of the hot rolled coil, which would cause the hot rolled coil to wear. When the hot rolled coil is conveyed to the vicinity of the cutter 9, the hot rolled coil is conveyed between the two support plates 7. The support plates 7 move closer to each other, which drives the positioning cylinder 21 to move. The positioning cylinder 21 corrects and centers the hot rolled coil, so that the hot rolled coil is cut evenly by the cutter 9, avoiding the cutting path deviation. The hot rolled coil is squeezed by the roller 14 and the extrusion roller 24, and the positioning cylinder 21 on the other side of the conveying roller 10 is used to further prevent the hot rolled coil from deviating after being cut.
[0023] A shearing method for a hot-rolled coil shearing device, implementing the hot-rolled coil shearing device described in the above embodiments, includes the following steps: Step 1: When shearing hot-rolled coil, the conveyor roller 10 and the cutter 9 are used to squeeze the hot-rolled coil. The cutter 9 shears the hot-rolled coil. The cut hot-rolled coil is conveyed to the outside of the drum 14 through the guide plate 22. The bolt 17 is rotated to drive the lifting plate 18 to move. The lifting plate 18 drives the extrusion roller 24 to move. The extrusion roller 24 and the drum 14 squeeze the hot-rolled coil. Then, the first screw 4 drives the sliding plate 13 to move. The sliding plate 13 drives the drum 14 to move. The movement of the extrusion roller 24 and the drum 14 tightens the hot-rolled coil to prevent the sheared hot-rolled coil from scratching the equipment. Step 2: When the hot-rolled coil enters between the conveyor roller 10 and the cutter 9, the second screw 12 is rotated to drive the support plate 7 to move. The support plate 7 drives the positioning cylinder 21 to stick to both sides of the hot-rolled coil to prevent the hot-rolled coil from shifting when it is conveyed between the conveyor roller 10 and the cutter 9.
