Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of polishing of black metal smelting and rolling products, in particular to a surface polishing device for black metal smelting and rolling products. BACKGROUND

[0002] Black metal smelting refers to an industrial production activity that uses iron, chromium, manganese and their ores as raw materials, and through a series of processes such as reduction, refining and impurity removal by professional smelting equipment such as blast furnace, converter and electric furnace, removes impurities such as sulfur, phosphorus and oxygen in the ore, and converts the ore into metal billets with certain composition and performance. Black metal smelting and rolling products refer to black metal products with specific shape, size and mechanical properties formed after the metal billets obtained by smelting are shaped by rolling processing. Polishing of black metal smelting and rolling products can remove the fine oxide layer, tiny burrs, processing marks and fine scratches generated during transportation on the surface of the products, so as to achieve high flatness and cleanliness of the product surface.

[0003] In the prior art, after smelting black metal, the black metal parts are shaped by rolling processing to obtain common steel plates, profiles and plates in daily life. When processing the workpieces after rolling, polishing is one of the key processing steps. When polishing the rolled workpieces, the plate is usually placed on one side of the polishing equipment, and the steel plate is reciprocated by the staff or mechanical equipment to achieve polishing of the steel plate. Although normal polishing of the steel plate can be achieved, only one side can be polished when polishing, and the plate needs to be turned over manually or by operating mechanical equipment when the other side needs to be polished. This not only increases the workload of the staff when polishing the steel plate, but also requires re-clamping of the steel plate in some cases, greatly reducing the polishing efficiency of double-sided polishing of the steel plate.

[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] Example 1: Please refer to Figures 1-9 The present invention provides a technical solution: a surface polishing device for ferrous metal smelting and rolling products, including a base plate 1, a mounting frame 2 and a fixing frame 3 fixedly connected to the top of the base plate 1, a connecting frame 4 fixedly connected to one side of the fixing frame 3, a rotating roller 10 rotatably connected to one side of the connecting frame 4, polishing sandpaper 11 being provided on the surface of the rotating roller 10, a polishing drive motor 12 fixedly connected to one side of the connecting frame 4, the output end of the polishing drive motor 12 passing through one side of the connecting frame 4 and fixedly connected to one side of the rotating roller 10, a fixing crossbar 6 fixedly connected to one side of the mounting frame 2, a moving block 7 slidably connected to the inner cavity of the fixing crossbar 6, and a flipping mechanism 8 being provided on one side of the moving block 7; The flipping mechanism 8 includes a rotating rod 801, the surface of which is rotatably connected to the inner cavity of the moving block 7. The rotating rod 801 is used to drive the rolled ferrous metal workpiece to flip. As a further definition of the flipping mechanism 8 of the present invention, a connecting rod 802 is fixedly connected to one end of the rotating rod 801, a rotating ring block 803 is fixedly connected to the surface of the connecting rod 802, a mounting block 806 is fixedly connected to one side of the rotating ring block 803, a spring 807 is fixedly connected to the inner cavity of the mounting block 806, a pawl block 808 is fixedly connected to one end of the spring 807, an inner ratchet block 804 is rotatably connected to the surface of the connecting rod 802, the inner cavity of the inner ratchet block 804 is rotatably connected to one side of the rotating ring block 803, a gear 805 is fixedly connected to the surface of the inner ratchet block 804, and the inner cavity of the inner ratchet block 804 meshes with the surface of the pawl block 808. One side of the fixed crossbar 6... A rack 809 is fixedly connected. The movable block 7 can be installed and connected to the connecting rod 802 via the rotating rod 801. At the same time, the connecting rod 802 can be connected to the rotating ring block 803. The rotating ring block 803 can be smoothly installed with the spring 807 and the pawl block 808 via the mounting block 806. When the rotating rod 801 rotates, it can smoothly drive the rotating ring block 803 to rotate synchronously, thereby realizing the rotation of the mounting block 806, the spring 807 and the pawl block 808. At the same time, the connecting rod 802 can also be connected to the gear 805 via the inner ratchet block 804. The surface of the gear 805 can mesh with the rack 809 on one side of the fixed cross column 6. Furthermore, when gear 805 meshes with rack 809 and rotates clockwise, it can smoothly push pawl block 808 through inner ratchet block 804, thereby realizing the rotation of pawl block 808, mounting block 806, rotating ring block 803, and connecting rod 802. The meshing of gear 805 with rack 809 can drive connecting rod 802 and rotating rod 801 to rotate 180 degrees. When moving block 7 drives gear 805 to move in the opposite direction, gear 805 will, through its own interaction with rack 809... The engagement of gear 805 causes the inner ratchet block 804 to rotate counterclockwise. At this time, the inner ratchet block 804 pushes the pawl block 808, causing the pawl block 808 to move inside the mounting block 806. This movement compresses the spring 807, which in turn applies a restoring elastic force to the pawl block 808. This causes the pawl block 808 to be continuously compressed and reset, so that gear 805 can only drive the rotating ring block 803 and the rotating rod 801 to rotate in one direction.

[0023] The inner cavity of the inner ratchet block 804 has an annular groove 17. An annular block 18 is fixedly connected to one side of the rotating ring block 803. The surface of the annular block 18 is slidably connected to the inner cavity of the annular groove 17. The rotating ring block 803 can install and fix the annular block 18, and the annular block 18 can rotate inside the annular groove 17. This means that when the rotating ring block 803 rotates clockwise due to the rotation of the gear 805, the annular block 18 can limit the rotation of the rotating ring block 803 through its connection with the annular groove 17. This not only increases the stability of the connection between the rotating ring block 803 and the inner ratchet block 804, but also reduces the possibility of one side of the rotating ring block 803 separating from the inner cavity of the inner ratchet block 804.

[0024] A reinforcing block 20 is slidably connected to one side of the fixed crossbar 6. The inner cavity of the reinforcing block 20 is rotatably connected to the surface of the rotating rod 801. A fixing plate 21 is fixedly connected to one side of the fixed crossbar 6. The surface of the reinforcing block 20 is slidably connected to one side of the fixing plate 21. The fixed crossbar 6 can connect the reinforcing block 20 and the fixing plate 21. The fixing plate 21 can limit the sliding of the reinforcing block 20 on one side of the fixed crossbar 6, so that it can slide stably and smoothly. The reinforcing block 20 can support and limit the rotating rod 801 through its connection with the fixed crossbar 6, so that it has high stability when rotating and moving, and is not prone to shaking or tilting.

[0025] A limiting rod 26 is fixedly connected to one side of the mounting block 806. The surface of the limiting rod 26 is slidably connected to the inner cavity of the pawl block 808. A limiting plate 19 is fixedly connected to the top of the fixed crossbar 6. The surface of the limiting plate 19 is slidably connected to the inner cavity of the moving block 7. The mounting block 806 can connect and install the limiting rod 26, which can limit the sliding of the pawl block 808, increase its stability when sliding, and limit the elastic extension and contraction of the spring 807, so that it is not easy to cause excessive deformation or bending when it elastically extends and contracts. The limiting plate 19 can limit the sliding of the moving block 7, thereby increasing the stability of the moving block 7 and the flipping mechanism 8 when moving.

[0026] The specific implementation of this embodiment is as follows: The operator can start the polishing drive motor 12 on one side of the connecting frame 4. When the polishing drive motor 12 is operating, it can smoothly drive the polishing sandpaper 11 and the rotating roller 10 to rotate. When the polishing sandpaper 11 rotates, it can polish the ferrous metal rolled workpiece. At the same time, the mounting bracket 2 fixed on the top of the base plate 1 can provide installation and connection for the fixed cross column 6, and the moving block 7 in the inner cavity of the fixed cross column 6 can slide stably. The rotating rod 801 rotatably connected inside the moving block 7... Used to drive the rolled ferrous metal workpiece to rotate. When the moving block 7 moves, it will drive the rotating rod 801 to move as well. The movement of the rotating rod 801 will drive the rotating ring block 803, the inner ratchet block 804 and the gear 805 to move synchronously. When the gear 805 moves to a certain distance, the teeth on the surface of the gear 805 will mesh with the teeth on the top of the rack 809. At this time, the gear 805 will rotate clockwise along the top of the rack 809, thereby driving the inner ratchet block 804 to rotate clockwise synchronously. The inner ratchet block 804, through its internal cavity meshing with the pawl block 808, exerts a pushing force on the pawl block 808. The pawl block 808 transmits this force to the rotating ring block 803 via the mounting block 806. The rotating ring block 803 then drives the rotating rod 801 to rotate via the connecting rod 802, achieving a 180-degree flip of the workpiece. When the moving block 7 moves in the opposite direction, the gear 805 rotates counterclockwise along the rack 809, driving the inner ratchet block 804 inside it to rotate counterclockwise synchronously. When the inner ratchet block 804 rotates, it will compress the pawl block 808, causing the pawl block 808 to slide along the surface of the limit rod 26 into the inner cavity of the mounting block 806 and compress the spring 807. After being compressed, the spring 807 will drive the pawl block 808 to elastically reset through its own elasticity. During the contact between the pawl block 808 and the inner ratchet block 804, the pawl block 808 will be continuously pushed to reset. During this process, the rotating rod 801 is not easy to follow the inner ratchet block 804 to rotate, thereby realizing the unidirectional rotation and flipping function of the rotating rod 801.

[0027] Example 2: Please refer to Figures 1-9 The present invention provides a technical solution: a surface polishing device for ferrous metal smelting and rolling products. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A clamping component 5 is provided on one side of the moving block 7, and a reciprocating mechanism 9 is provided at the bottom of the fixed cross column 6.

[0028] As a further definition of the reciprocating mechanism 9 and clamping assembly 5 of the present invention, the reciprocating mechanism 9 includes a moving rod 910, the surface of which is slidably connected to the inner cavity of the fixed crossbar 6, one end of which is fixedly connected to the bottom of the moving block 7, and the moving rod 910 is used to drive the moving block 7 to reciprocate. A connecting plate 901 is fixedly connected to one end of the moving rod 910, a track groove 902 is provided at the bottom of the connecting plate 901, a plurality of fixed ring blocks 903 are fixedly connected to the bottom of the connecting plate 901, a slider 904 is slidably connected to the surface of the connecting plate 901, a moving plate 905 is slidably connected to one side of the slider 904, and the bottom of the moving plate 905 is fixedly connected to... A hollow block 906 is connected to the bottom of the hollow block 906, and a mounting plate 907 is fixedly connected to the bottom of the mounting plate 907. A second servo motor 909 is fixedly connected to the bottom of the mounting plate 907. The output end of the second servo motor 909 passes through the bottom of the mounting plate 907 and is fixedly connected to a slide rod 911. The surface of the slide rod 911 is slidably connected to the inner cavity of the track groove 902. A rotating block 908 is rotatably connected to the top of the moving plate 905. The inner cavity of the rotating block 908 is fixedly connected to the surface of the slide rod 911. The surface of the rotating block 908 meshes with the surface of one of the fixed ring blocks 903. The mounting frame 2 can connect the slider 904 and the fixed ring block 903 through the connecting plate 901. Furthermore, multiple fixed ring blocks 903 are arranged in a linear array, while the slider 904 can slide smoothly on the surface of the connecting plate 901. Simultaneously, the slider 904 can be connected to the moving block 7 via the moving rod 910, thus enabling the moving block 7 to move synchronously when the slider 904 moves. The slider 904 can be connected to the connecting hollow block 906 via the moving plate 905, and the second servo motor 909 is installed through the connection between the connecting hollow block 906 and the mounting plate 907. When the second servo motor 909 is operating, it can... The sliding rod 911 and the rotating block 908 are smoothly driven to rotate. The sliding rod 911 slides inside the track groove 902. The surface of the rotating block 908 engages with one of the fixed ring blocks 903. The multiple fixed ring blocks 903 are the same size and shape. This allows the rotating block 908 to smoothly drive the sliding rod 911 to drive the slider 904 to move continuously on the surface of the connecting plate 901 through its engagement with the fixed ring blocks 903. During the movement, the slider 904 and the moving rod 910 are moved back and forth continuously, thereby realizing the reciprocating movement of the slider 904 and the moving rod 910.

[0029] The clamping assembly 5 includes a hollow plate 501. One side of the hollow plate 501 is fixedly connected to one end of the rotating rod 801. The hollow plate 501 is used to clamp the rolled ferrous metal workpiece. A first servo motor 503 is fixedly connected to one side of the hollow plate 501. The output end of the first servo motor 503 passes through one side of the hollow plate 501 and is fixedly connected to a bidirectional threaded rod 502. Threaded blocks 504 are threadedly connected to the surface of the bidirectional threaded rod 502. Two threaded blocks 504 are provided. The surfaces of the two threaded blocks 504 are slidably connected to the inner cavity of the hollow plate 501. A clamping plate 505 is fixedly connected to one side of each of the two threaded blocks 504. The rotating rod 801 can be connected to the first servo motor 503 through the hollow plate 501. The first servo motor 503 can not only install the bidirectional threaded rod 502, but also smoothly drive the bidirectional threaded rod 502 to rotate during its own operation. The threads on both sides of the bidirectional threaded rod 502 are opposite. Furthermore, when the bidirectional threaded rod 502 rotates, it can smoothly drive the two threaded blocks 504 inside the hollow plate 501 to slide and move in opposite directions. When the threaded blocks 504 move, they can drive the clamping plates 505 to move together, so that the two clamping plates 505 can smoothly and steadily clamp and fix the workpiece to be polished. At the same time, the movement of the slider 904 will drive the hollow plate 501 to move together through the moving block 7 and the rotating rod 801. When the rotating rod 801 rotates, it will also drive the hollow plate 501 to rotate synchronously. Thus, when the clamping assembly 5 clamps and fixes the workpiece, it can smoothly drive the workpiece to reciprocate and automatically flip, thereby achieving efficient polishing of the workpiece.

[0030] A spray block 13 is fixedly connected to one side of the fixed frame 3, and a water tank 16 is fixedly connected to one side of the fixed frame 3. A connecting pipe 14 is fixedly connected to the inner cavity of the spray block 13. One end of the connecting pipe 14 passes through one side of the spray block 13 and the water tank 16. A water pump 15 is fixedly connected to the surface of the connecting pipe 14. An annular groove 17 is fixedly connected to the inner cavity of the water tank 16. An annular block 18 is fixedly connected to the surface of the annular groove 17. The water tank 16 can store pure water, and the water pump 15 can pump the pure water in the water tank 16 into the connecting pipe 14 through its own operation. Through the connection between the connecting pipe 14 and the spray block 13, the pure water is sprayed out from the inside of the spray block 13. This allows the polishing sandpaper 11 to effectively reduce the splashing of debris and the high temperature generated during polishing when polishing the workpiece, thereby improving the safety of polishing the workpiece.

[0031] A limiting rod 22 is fixedly connected to the inner cavity of the fixed horizontal column 6. The surface of the limiting rod 22 is slidably connected to the inner cavity of the moving rod 910. A T-shaped plate 23 is fixedly connected to the top of the connecting plate 901. The inner cavity of the slider 904 is slidably connected to the surface of the T-shaped plate 23. The fixed horizontal column 6 can connect to the limiting rod 22. The limiting rod 22 can limit the sliding of the moving rod 910 by utilizing its connection with the moving rod 910. This prevents the moving rod 910 from rotating or wobbling slightly while it drives the moving block 7 to move back and forth. The T-shaped plate 23 can increase the stability of the slider 904 when it slides on the surface of the connecting plate 901, making it less likely to deviate or slide too far when it slides on the surface of the connecting plate 901.

[0032] Both sides of the slider 904 are fixedly connected to baffles 24, and the surface of the rotating rod 801 is fixedly connected to a reinforcing plate 25. One side of the reinforcing plate 25 is fixedly connected to one side of the hollow plate 501. The baffles 24 can restrict the moving plate 905. When the rotating block 908 rotates and moves around the surface of multiple fixed ring blocks 903, it will drive the moving plate 905 to slide in the inner cavity of the slider 904. The baffles 24 can effectively reduce the situation where the moving plate 905 slides out of the slider 904. The reinforcing plate 25 can strengthen and reinforce the connection between the rotating rod 801 and the hollow plate 501, so that the connection between the two can be more firm and stable when the rotating rod 801 drives the hollow plate 501 to flip and rotate.

[0033] The specific implementation of this embodiment is as follows: During operation, the operator can place the rolled ferrous metal workpiece between two clamping plates 505 and start the first servo motor 503. When the first servo motor 503 is operating, it can drive the bidirectional threaded rod 502 to rotate. Because the threads on both sides of the bidirectional threaded rod 502 are in opposite directions, when the bidirectional threaded rod 502 rotates, it can drive the two threaded blocks 504 to slide in opposite directions in the inner cavity of the hollow plate 501. When the two threaded blocks 504 slide, they can drive the two clamping plates 505. By bringing them closer together, a stable clamping of the workpiece is achieved. Then, the operator can activate the second servo motor 909, which drives the slide rod 911 and the rotating block 908 to rotate synchronously. Because the rotating block 908 meshes with the fixing ring block 903 at the bottom of the connecting plate 901, the rotating block 908, under the meshing force, drives the slide rod 911 to slide inside the track groove 902. Simultaneously, it drives the moving plate 905, the connecting hollow block 906, the mounting plate 907, and the slider 904 to move along the surface of the connecting plate 901. The rotating block 908 continuously moves while multiple fixed ring blocks 903 are arranged in a linear array. The rotating block 908 engages sequentially with fixed ring blocks 903 at different positions, thereby driving the slider 904 to continuously reciprocate on the surface of the connecting plate 901. The slider 904, via the moving rod 910, drives the moving block 7 to reciprocate within the cavity of the fixed crossbar 6. The moving block 7, in turn, drives the clamping assembly 5 and the clamped ferrous rolled workpiece to reciprocate synchronously. During this movement, the workpiece comes into contact with the high-speed rotating polishing sandpaper 11, achieving polishing of one side of the workpiece. In the polishing operation, after one side of the workpiece is polished, the moving block 7 will continue to drive the flipping mechanism 8 to move. At this time, the gear 805 and the rack 809 mesh with each other. The gear 805 drives the inner ratchet block 804, the pawl block 808 and the rotating rod 801 to rotate, driving the rotating rod 801 to rotate 180 degrees. When the rotating rod 801 rotates, it will drive the clamping assembly 5 and the workpiece to flip synchronously. After the flipping is completed, the reciprocating mechanism 9 continues to drive the workpiece to move back and forth, so that the other side of the workpiece is in full contact with the polishing sandpaper 11, completing the double-sided polishing operation.
