Description

Technical Field

[0001] This utility model belongs to the field of steel ingot processing technology, and specifically relates to a surface treatment structure for steel billet casting. Background Technology

[0002] The surface treatment structure for steel billet ingots is used to grind the surface of steel ingots during processing to remove minor surface defects, improve surface smoothness, meet the requirements of high-precision processing, or polish the surface to give it a metallic luster, improve surface cleanliness and roughness, enhance the adhesion of subsequent coatings or processing, and prepare for subsequent steel ingot processing steps.

[0003] Current steel billet ingot surface treatment structures include a surface grinding device for round steel ingots. If this device needs to grind round steel ingots of different diameters, different grinding equipment needs to be replaced, increasing processing costs. Furthermore, if the grinding rollers or bottom support wheels need to be replaced and maintained after long-term use, a lot of time is required, affecting subsequent steel ingot surface treatment and resulting in reduced processing costs. Utility Model Content

[0004] The purpose of this utility model is to provide a surface treatment structure for steel ingots used in steel billet casting. Its advantages are that it can support steel ingots of different diameters during grinding, and can quickly disassemble components that are in direct contact with the steel ingot and are subject to wear during the grinding process.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a surface treatment structure for steel billet casting, comprising a load-bearing frame, an extension component fixedly installed on the top of the load-bearing frame, the extension component comprising two threaded sleeves, a movable plate fixedly installed between the two sides of the threaded sleeves, a limit rod fixedly installed on the right side of the movable plate, a positioning plate slidably connected to the surface of the limit rod, an installation component fixedly installed on the top of both the movable plate and the positioning plate, the installation component comprising an installation frame, a support wheel rotatably connected to the inner cavity of the installation frame via a bearing, a steering component provided on the rear side of the extension component, the steering component comprising a limit shell, the bottom of the limit shell fixedly installed to the load-bearing frame, a grinding component slidably connected to the inner cavity of the limit shell, and a motor four fixedly installed on the top of the right side of the installation frame, the output end of the motor four engaging with the support wheel.

[0006] The above technical solution is as follows: When it is necessary to adjust the gap between the support structures before grinding round steel ingots of different diameters, start motor one. Motor one drives the threaded sleeve connected to its surface threaded through a bidirectional threaded rod, and the movable plate fixed thereto moves away from the center of the positioning shell. When the movable plate moves, it drives the structure fixed thereto to move. When the movable plate moves to the designated position, the motor is turned off, thus completing the adjustment of the gap between the support structures before grinding round steel ingots of different diameters. When it is necessary to disassemble the worn structure, the user will pull the mounting rod or retaining rod in the mounting component or grinding component that needs to be disassembled from the mounting component or grinding component. Then the user can disassemble the mounting frame and the fixing frame, and then complete the disassembly of the support wheel and the grinding roller. This allows for the quick disassembly of the structure that needs to be in direct contact with the steel ingot and is worn during use.

[0007] The present invention is further configured such that the extension component includes a positioning shell, the bottom of the positioning shell is fixedly installed with the load-bearing frame, a motor is fixedly installed on the front side of the positioning shell, the output end of the motor penetrates into the inner cavity of the positioning shell and is fixedly installed with a bidirectional threaded rod, and the opposite sides of the surface of the bidirectional threaded rod are threadedly connected to the threaded sleeve.

[0008] The above technical solution is adopted: the double-threaded rod is driven by a motor to rotate, and the reverse threads on its surface drive the two threaded sleeves to move synchronously in opposite directions. Then, the movable plate drives the mounting components and the structure connected to them to move away from or closer to each other, so as to realize the rapid adjustment of the support wheel spacing to adapt to round steel ingots of different diameters.

[0009] The present invention is further configured such that the bottom of each mounting bracket and the adjacent movable plate or positioning plate are fixedly installed, the inner cavity of the mounting bracket is slidably connected to a limiting bracket, the inner cavity of the limiting bracket is engaged with a support wheel, and a mounting rod is fixedly installed on the rear side of the right side of the limiting bracket, the surface of the mounting rod is slidably connected to the inner cavity of the mounting bracket.

[0010] The above technical solution allows for the sliding of the limiting frame within the mounting frame, enabling quick installation of the support wheels inside the mounting frame. The mounting rod positions the limiting frame during installation, facilitating user installation. The sliding fit between the mounting rod and the mounting frame facilitates quick disassembly and assembly of the limiting frame and support wheels, providing convenience for replacing worn support wheels.

[0011] The present invention is further configured such that a limiting rod is slidably connected to each pair of limiting frames on opposite sides, and the bottom of the surface of the limiting rod is slidably connected to the mounting frame.

[0012] The above technical solution is adopted: the limiting rod constrains the limiting frame to prevent it from detaching from the mounting frame during use, ensuring the contact between the support wheel and the steel ingot, and the sliding connection with the mounting frame, thus avoiding the positional deviation of the limiting frame during use.

[0013] The present invention is further configured such that a second motor is fixedly installed on the left side of the limiting shell, and a limiting shaft is fixedly installed on the right side of the second motor through the inner cavity of the limiting shell. A toothed ring is slidably connected to the top of the inner cavity of the limiting shell, and a toothed belt meshes with the opposite side of the surface of the toothed ring and the limiting shaft. The inner cavity of the toothed ring meshes with the grinding assembly.

[0014] The above technical solution is adopted: the motor drives the limit shaft to rotate, and the toothed belt drives the toothed ring to rotate. The meshing of the toothed ring with the grinding component can adjust the angle of the grinding component, so that the grinding roller can adapt to the surface curvature of the steel ingot and adapt to the grinding of steel ingots of different diameters, thereby realizing the flexible adjustment of the grinding component and improving the uniformity of the surface treatment of the steel ingot.

[0015] The present invention is further configured such that the grinding assembly includes a retaining frame, the rear side of which is slidably connected to the inner cavity of the limiting shell, a motor three is fixedly installed on the rear side of the left side of the retaining frame, a transmission shaft is fixedly installed on the output end of the motor three, the surface of the transmission shaft is slidably connected to the inner cavity of the retaining frame, a positioning shaft is slidably connected to the front side of the right side of the retaining frame, a transmission belt is drively connected between the surfaces of the positioning shaft and the transmission shaft, a grinding roller is rotatably connected to the inner cavity of the retaining frame, the right side of the grinding roller is engaged with the positioning shaft, a fixing frame is engaged with the left side of the grinding roller, the rear side of the left side of the fixing frame is engaged with the retaining frame, a retaining rod is slidably connected to the rear side of the fixing frame, and the surface of the retaining rod is slidably connected to the retaining frame.

[0016] The above technical solution involves a motor driving a transmission shaft to rotate, which in turn drives a positioning shaft via a transmission belt to rotate a grinding roller, thus achieving grinding of the surface of the steel ingot requiring surface treatment. The fixed frame and the retaining rod work together to fix the grinding roller inside the fixed frame, preventing it from shaking during high-speed rotation. The combination of the snap-fit ​​and sliding structures facilitates quick disassembly and replacement of the grinding roller, improving the maintenance efficiency of worn parts. The sliding connection between the fixed frame and the limiting shell can adjust the distance between the grinding roller and the steel ingot, adapting to the grinding needs of steel ingots of different diameters or grinding needs of different depths.

[0017] The present invention is further configured such that a retaining shaft is rotatably connected to the inner cavity of the transmission belt, and a retaining ring is slidably connected to the left side of the retaining shaft through the retaining frame.

[0018] The above technical solution is adopted: the transmission belt is positioned by the retaining shaft to avoid slippage during transmission, and the retaining ring provides axial limit to the retaining shaft to prevent displacement when the transmission belt is running.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. When it is necessary to adjust the gap between the support structures before grinding round steel ingots of different diameters, start motor one. Motor one drives the threaded sleeve connected to its surface and the movable plate fixed to it away from the center of the positioning shell through the double-threaded rod. When the movable plate moves, it drives the structure fixed to it to move. When the movable plate moves to the designated position, the motor is turned off, and the adjustment of the gap between the support structures before grinding round steel ingots of different diameters is completed.

[0021] 2. When it is necessary to disassemble the worn structure, the user will pull the mounting rod or retaining rod from the mounting or grinding assembly to be disassembled. Then the user can disassemble the mounting bracket and the fixing bracket, and then disassemble the support wheel and the grinding roller. This allows for the quick disassembly of the structure that has direct contact with the steel ingot and is worn. Attached Figure Description

A movable plate 3 is fixedly installed between the two sides of the threaded sleeves 204. A limit rod 604 is fixedly installed on the right side of the movable plate 3. A positioning plate 5 is slidably connected to the surface of the limit rod 604. A motor 4 10 is fixedly installed on the top right side of the mounting frame 601.

[0032] Brief description of usage: Before grinding round steel ingots of different diameters, when adjusting the gap between the support structures, the user starts motor 202. Motor 202 drives the bidirectional threaded rod 203 to rotate. The rotating bidirectional threaded rod 203, through the threaded sleeve 204 connected to its surface thread, moves the movable plate 3 fixed to it away from the center of the positioning shell 201. When the movable plate 3 moves, it drives the structure fixed to it to move.

A toothed belt 805 meshes with the opposite side of the surfaces of the toothed ring 804 and the limiting shaft 803. The inner cavity of the toothed ring 804 meshes with the grinding assembly 9.

A motor 902 is fixedly installed on the rear side of the left side of the retaining frame 901. A transmission shaft 903 is fixedly installed at the output end of the motor 902. The surface of the transmission shaft 903 is slidably connected to the inner cavity of the retaining frame 901. A positioning shaft 904 is slidably connected to the front side of the right side of the retaining frame 901. A transmission belt 905 is connected between the surfaces of the positioning shaft 904 and the transmission shaft 903. A grinding roller 906 is rotatably connected to the inner cavity of the retaining frame 901. The right side of the grinding roller 906 is engaged with the positioning shaft 904.

[0039] Furthermore, the inner cavity of the transmission belt 905 is rotatably connected to a retaining shaft 909, and the left side of the retaining shaft 909 passes through the retaining frame 901 and is slidably connected to a retaining ring 910.

[0040] Brief Description of Usage: When disassembling a structure that directly contacts and is subject to wear on a steel ingot, the user should turn off the running motors 202, 802, and 902. Then, remove the mounting rod 603 or retaining rod 908 from the mounting assembly 6 or grinding assembly 9. The user can then disassemble the mounting bracket 601 and fixing bracket 907 within the mounting assembly 6 or grinding assembly 9, thereby disassembling the support wheel 7 and grinding roller 906. When reassembling, reinstall the same type of support wheel 7 and grinding roller 906 into the mounting bracket 601 and retaining bracket 901 of the mounting assembly 6 or grinding assembly 9, and then... 601 and the fixing frame 907 are re-fixed to the mounting frame 601 and the fixing frame 901 by the mounting rod 603 or the retaining rod 908, which allows for quick assembly and disassembly of structures that need to directly contact steel ingots and are subject to wear. The sliding of the limiting frame 602 within the mounting frame 601 allows for quick installation of the support wheel 7 inside the mounting frame 601. The mounting rod 603 positions the limiting frame 602 during installation, facilitating user installation. The sliding engagement of the mounting rod 603 with the mounting frame 601 facilitates quick assembly and disassembly of the limiting frame 602 and the support wheel 7, providing a convenient means of replacing the worn support wheel 7. For convenience; the limiting rod 604 constrains the limiting frame 602 to prevent it from detaching from the mounting frame 601 during use, ensuring contact between the support wheel 7 and the steel ingot, and maintaining a sliding connection with the mounting frame 601, thus preventing the limiting frame 602 from shifting position during use; the second motor 802 drives the limiting shaft 803 to rotate, which in turn drives the toothed ring 804 to rotate via the toothed belt 805. The meshing of the toothed ring 804 with the grinding assembly 9 adjusts the angle of the grinding assembly 9, allowing the grinding roller 906 to adapt to the surface curvature of the steel ingot and to grind steel ingots of different diameters, achieving flexible adjustment of the grinding assembly 9 and improving the uniformity of the steel ingot surface treatment; the third motor 902 drives the transmission shaft 903 to rotate, which in turn drives the positioning shaft 904 via the transmission belt 905. The grinding roller 906 is driven to rotate, realizing the grinding operation on the surface of the steel ingot that needs surface treatment. The fixing frame 907 and the fixing rod 908 cooperate to fix the grinding roller 906 in the fixing frame 901 to prevent it from shaking during high-speed rotation. The combination of the snap-fit ​​and sliding structure facilitates the quick disassembly and replacement of the grinding roller 906, improving the maintenance efficiency of worn parts. The sliding connection between the fixing frame 901 and the limiting shell 801 can adjust the distance between the grinding roller 906 and the steel ingot to adapt to the grinding needs of steel ingots of different diameters or grinding needs of different depths. The fixing shaft 909 positions the transmission belt 905 to avoid slippage during transmission. The fixing ring 910 forms an axial limit on the fixing shaft 909 to prevent it from shifting when the transmission belt 905 is running.
