Description

Technical Field

[0001] This invention relates to the field of ESP hot rolling production technology, specifically to a high-speed laser cladding device for ESP hot rolling production line rolls. Background Technology

[0002] Rolls are the main equipment in steel rolling, and their quality plays a crucial role in the quality and quantity of steel produced. After long-term rolling use, the radius of the roll in the middle decreases, and pits and depressions form on the surface, which seriously affects the quality of the rolled steel. To extend the service life of the rolls, it is usually necessary to repair the working surface of the rolls. Laser cladding technology is an advanced surface modification technology that involves cladding materials onto the substrate surface. Laser irradiation causes both the cladding material and a thin layer on the substrate surface to melt simultaneously and solidify rapidly, forming a surface coating with extremely low dilution and a metallurgical bond to the substrate material. This significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the substrate material surface.

[0003] A search revealed a Chinese patent document disclosing a C-type laser cladding device for surface strengthening of ESP hot rolling rolls [Announcement No.: CN223633466U]. This C-type laser cladding device for surface strengthening of ESP hot rolling rolls includes a laser cladding device. A support plate is fixedly connected to the upper surface of the laser cladding device. A support plate is slidably connected through the upper surface of the support plate. An adjustment mechanism is provided on the right surface of the support plate. The adjustment mechanism includes a drive component and a positioning component. A support component is provided on the upper surface of the support plate. The drive component includes a connecting plate. A servo motor is provided on the front surface of the connecting plate. A threaded rod is fixedly connected to the output shaft of the servo motor.

[0004] The laser cladding equipment disclosed in this patent can flexibly adjust the position of the pallet and support components to provide support for different models of ESP hot rolling rolls. However, this adjustment method can only be adjusted by moving up and down, and it is inconvenient to adjust the length left and right. If the length of the rolling roll is long, the stability of the support is reduced. Furthermore, when using laser cladding to process materials, a corresponding powder feeder is required to transport the powder. In actual use, the powder is placed in the material cylinder and transported by the pneumatic mechanism inside the powder feeder. However, due to the physical characteristics of the powder, it is easy for the powder to adhere to the inner wall of the material cylinder. This residual powder is not easily transported out by the pneumatic mechanism, resulting in the waste of some powder. Summary of the Invention

The support plate is arc-shaped and is fixed to the top of the first folded plate and the second folded plate respectively; The force-applying component is located inside the worktable and is used to apply force to the screw.

[0010] Preferably, the force-applying component includes: A worm gear is rotatably connected to the surface of the worktable, and a crank handle is fixed to the front end of the worm gear; A worm gear is fixed to the surface of the bottom two ends of the screw, and the worm gear meshes with the rear end surface of the worm.

[0011] Preferably, the support further includes a pushing member, the pushing member comprising: A roller frame is fixed to the bottom of the folding plate. A roller is rotatably connected inside the roller frame, and a half gear is fixed on the surface of the roller shaft. The second rack plate slides through the interior of the fixed plate.

The striking component is located on the back of the powder feeder at the mobile frame.

[0012] Preferably, the striking element includes: A mounting plate is fixed to the back of the movable frame, and a knocking rod slides through the interior of the other end of the mounting plate. A knocking pad is fixed to one end of the knocking rod. Spring one is sleeved on the surface of the hammer rod, and the two ends of spring one are respectively fixed to one side of the mounting plate and one side of the hammer rod fixing plate; A flip plate is hinged to one side of the mounting plate. One end of the flip plate is connected to a connecting rod via a ball joint, and the other end of the connecting rod is connected to the other end of the knocking rod via a ball joint.

At the same time, through the sliding connection of the second folded plate inside the fixed plate, the distance between the first folded plate and the second folded plate can also be adjusted. This allows for the support of rolls of different lengths, thereby improving the stability during support.

[0017] This invention enables the sliding shell to move left and right on the back side by driving the first moving component, and enables the connecting plate and laser head to move up and down by driving the second moving component. Through multiple adjustments and movements, costs can be reduced, making it easier to perform laser cladding later.

[0018] The present invention uses the rotation of the rollers to drive the rollers to rotate, which in turn drives the rack plate and the push plate to move. The striking element reciprocates to strike the surface of the powder feeder on one side of the moving frame, causing the powder adhering to the inner wall of the powder feeder to fall off, thereby reducing the waste of resources.

[0021] 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.

[0022] Please see Figure 1-8 As shown, a high-speed laser cladding device for rolls in an ESP hot rolling production line includes a worktable 100, a movable part 200 installed at the rear of the worktable 100, and a laser head 300 installed at the front end of the movable part 200. The movable part 200 includes a sliding shell 210 slidably connected to the rear of the worktable 100. A first movable component 230 is provided inside the sliding shell 210. A movable frame 220 is fixed to the top of the sliding shell 210. A connecting plate 240 is slidably connected to the surface of the movable frame 220. A second movable component 250 is provided inside the movable frame 220 for moving the connecting plate 240. The front end of the connecting plate 240 is fixed to the back of the laser head 300.

[0023] The moving part 230 includes a motor 231 fixed inside the sliding housing 210. The output shaft of the motor 231 is bolted with a gear 232. A rack plate 233 is fixed to the bottom of the back of the worktable 100. The top of the rack plate 233 meshes with the bottom of the gear 232. When the roll is clad, the motor 231 drives the gear 232 to rotate, and the rack plate 233 drives the sliding housing 210 and the moving frame 220 to move together.

[0024] The second movable component 250 includes a second motor 251 fixed to the top of the movable frame 220. The output shaft of the second motor 251 is bolted with a first screw 252, and the other end of the first screw 252 is rotatably connected to the inner wall of the movable frame 220. A threaded sleeve 253 is threaded onto the surface of the first screw 252. The front end of the threaded sleeve 253 is fixed to the back of the connecting plate 240. When the connecting plate 240 is moved up and down, the second motor 251 drives the first screw 252 to rotate and the threaded sleeve 253 to move, thereby adjusting the connecting plate 240.

[0025] It also includes a support part 400 for supporting the roll. The support part 400 includes a second screw 460 rotatably connected inside the worktable 100. A fixing sleeve 470 is threadedly connected to the surface of the second screw 460. A fixing plate 410 is fixed to the top of the fixing sleeve 470. A first folding plate 420 is fixed to the left end of the fixing plate 410. A second folding plate 430 is slidably connected to the right side of the top of the fixing plate 410. A support plate 440 is fixed to the top of both the first folding plate 420 and the second folding plate 430. The support plate 440 is arc-shaped. A force-applying component 450 is provided inside the worktable 100 for applying force to the second screw 460. Depending on the size of the roll, after the roll is located on top of the support plate 440, the force applied by the force-applying component 450 can drive the second screw 460 to rotate and drive the fixing sleeve 470 to move up and down. At the same time, it can drive the fixing plate 410 to move together, thereby adjusting the height of the support plate 440 to improve the stability during support.

[0026] The force-applying component 450 includes a worm gear 452 that is rotatably connected to the surface of the worktable 100. A crank handle 451 is fixed to the front end of the worm gear 452. A worm wheel 453 is fixed to the surface of the bottom end of the screw 460. The worm wheel 453 meshes with the rear end surface of the worm gear 452. When the screw 460 is rotated, the crank handle 451 can be turned, which in turn drives the worm gear 452 to rotate, which in turn drives the worm wheel 453 to rotate, thereby driving the screw 460 to rotate.

[0027] The support part 400 also includes a pusher 480, which includes a roller frame 481 fixed to the bottom of the folding plate 420. A roller 482 is rotatably connected inside the roller frame 481. A half gear 483 is fixed to the surface of the roller 482's shaft. A rack plate 484 slides through the inside of the fixing plate 410. The top of the rack plate 484 meshes with the bottom of the half gear 483. A push plate 485 is fixed to the other end of the rack plate 484. A striking element 486 is provided on the back of the powder feeder at the moving frame 220. When the roller 482 contacts the bottom of the roller, the roller 482 will rotate and drive the half gear 483 to rotate. At the same time, it will drive the rack plate 484 to move backward and drive the push plate 485 to apply force to the striking element 486, so as to strike the powder feeder.

[0028] The striking component 486 includes a mounting plate 4861 fixed to the back of the movable frame 220. A striking rod 4862 slides through the interior of the other end of the mounting plate 4861. A striking pad 4863 is fixed to one end of the striking rod 4862. A spring 4864 is sleeved on the surface of the striking rod 4862. The two ends of the spring 4864 are respectively fixed to one side of the mounting plate 4861 and one side of the fixing plate of the striking rod 4862. A flip plate 4865 is hinged to one side of the mounting plate 4861. One end of 65 is connected to a connecting rod 4866 via a universal ball joint, and the other end of the connecting rod 4866 is connected to the other end of the striking rod 4862 via a universal ball joint. When pushed by the push plate 485, it will push one end of the flip plate 4865, causing the flip plate 4865 to deflect. The other end of the flip plate 4865 will push the connecting rod 4866 and drive the striking rod 4862 to move together, so that the striking pad 4863 can reciprocate to strike the powder feeder.

[0029] The pusher 480 also includes a spring 487, which further includes a slide rod 4871 that slides through the fixed plate 410. The other end of the slide rod 4871 is fixed to one side of the rack plate 484. A spring 4872 is sleeved on the surface of the slide rod 4871. The two ends of the spring 4872 are fixed to one side of the rack plate 484 and one side of the fixed plate 410, respectively. When the rack plate 484 moves backward, it will drive the slide rod 4871 to move together inside the fixed plate 410, and at the same time, it will stretch the spring 4872. After the force applied to the rack plate 484 is released, it will return to the starting position through the stretching force of the rack plate 484.

[0030] The top of one end of the folded plate 430 is threaded with a fastening bolt 500, and the other end of the fastening bolt 500 is used to cooperate with the inner side of the fixing plate 410. The fastening bolt 500 can be used to fix the folded plate 430 after it has been moved.

[0031] The inner side of the support plate 440 is connected with several rolling balls 600, which are arranged at equal intervals. This arrangement can reduce the friction between the roller and the support plate 440, thereby facilitating better rotation.

[0032] Working principle: In use, the roller can be placed on top of the support plate 440. Then, according to the size of the roller, the screw 460 is rotated by the force-applying component 450, thereby driving the fixed sleeve 470 to move up and down, thereby adjusting the height of the fixed plate 410 so that one end of the roller can be inserted and fixed with one end of the three-jaw chuck. If the roller is long, the folding plate 430 can be pulled to the right for better support. Then, the moving component 230 can drive the moving frame 220 and the sliding shell 210 to move. After moving, the connecting plate 240 can be moved downward by the moving component 250 so that the laser head 300 can be located at the cladding position of the roller. Then, the three-jaw chuck can be rotated by the worktable 100, thereby driving the roller to rotate and clad. As the roller rotates, it will drive the roller 482 to rotate as well, and the pusher 480 will reciprocate to knock the powder feeder, thereby reducing resource waste.
