Description

Technical Field

[0001] This utility model relates to the technical field of metallurgical continuous casting equipment, specifically a device for strengthening and grinding the inner arc surface of a continuously cast crystallized copper plate. Background Technology

[0002] As a core piece of equipment in the continuous casting process for steel and non-ferrous metals, the condition of the copper plates inside the continuous casting mold directly determines the surface quality of the cast billet, the cooling efficiency of the mold, and the service life of the equipment. Under harsh conditions of high temperature, high wear, and cyclic thermal stress, the inner arc surface of the crystallizing copper plate is prone to problems such as thickening of the oxide layer, propagation of surface microcracks, and fatigue spalling of copper material. This leads to an increase in the surface defect rate of the cast billet, an increased risk of steel leakage, and even unplanned shutdowns to replace the mold, seriously affecting the continuity and economy of the continuous casting production line. Therefore, regularly strengthening and polishing the inner arc surface of the crystallizing copper plate to repair surface damage and restore geometric accuracy has become a key technical link to ensure the efficient and stable operation of continuous casting.

[0003] In current continuous casting crystallized copper plate inner arc surface strengthening and grinding devices, the grinding wheel usually adopts a rigid connection structure with a fixed angle or a limited range. Due to the significant difference in the curvature of the inner arc surface of different crystallization pairs, and the possibility of local arc deformation of the same grinding wheel after long-term use, a mismatch may occur between the grinding wheel and the arc surface contact area, which urgently needs to be improved.

[0004] The purpose of this invention is to provide a device for strengthening and polishing the inner arc surface of a continuously cast crystalline copper plate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for strengthening the inner arc surface of a continuously cast crystalline copper plate, comprising a frame, a transmission mechanism at the top of the frame, a drive motor at the right end of the transmission mechanism, a grinding wheel at the bottom of the drive motor, an adjustment component between the drive motor and the grinding wheel, the drive motor being connected to the grinding wheel through the adjustment component, a cylinder at the bottom of the frame below the drive motor, and a processing platform fixedly connected to the top of the cylinder;

[0006] The adjustment assembly includes a fixed base mounted on the bottom surface of the drive motor. A rotating rod is rotatably connected inside the fixed base, and a bolt is slidably connected inside the rotating rod. A grinding wheel is fixedly connected to the bottom of the bolt.

[0007] As a further preferred embodiment of this technical solution, the rotating ring is designed in a fan shape, and a through hole is provided in the middle of the rotating ring.

[0008] As a further preferred embodiment of this technical solution, the threaded grooves are provided in eight groups, and all eight groups of threaded grooves are designed with equal spacing.

[0009] As a further preferred embodiment of this technical solution, the surface of the processing platform is provided with a protective component. The protective component includes a movable compartment disposed on the front surface of the processing platform. A bidirectional lead screw is rotatably connected inside the movable compartment. A handle is fixedly connected to the right end of the bidirectional lead screw. Two sets of transmission blocks are threaded onto the bidirectional lead screw.

[0012] This utility model provides a device for strengthening and polishing the inner arc surface of a continuously cast crystallized copper plate, which has the following beneficial effects:

[0013] 1. This utility model utilizes a threaded rod that rotates within and exits a threaded groove. A rotating ring then drives a rotating rod to rotate within a fixed base, simultaneously aligning the threaded groove on the rotating ring with the threaded rod until the grinding wheel angle is adjusted to the desired position. Finally, the threaded rod is threaded into the threaded groove, thereby adjusting the grinding wheel angle.

At the same time, the extension plate slides into the insertion slot, forming a protective area to prevent debris generated when the grinding wheel grinds the crystallized copper plate from flying out and causing injury to the workers.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a continuous casting crystallized copper plate inner arc surface strengthening and grinding device includes a frame 1, a transmission mechanism 2 is provided at the top of the frame 1, a drive motor 3 is provided at the right end of the transmission mechanism 2, a grinding wheel 4 is provided at the bottom of the drive motor 3, an adjustment component 7 is provided between the drive motor 3 and the grinding wheel 4, the drive motor 3 is connected to the grinding wheel 4 through the adjustment component 7, a cylinder 5 is provided at the bottom of the frame 1 below the drive motor 3, and a processing platform 6 is fixedly connected to the top of the cylinder 5;

[0022] The adjustment assembly 7 includes a fixed base 71 mounted on the bottom surface of the drive motor 3. A rotating rod 72 is rotatably connected inside the fixed base 71. A bolt 73 is slidably connected inside the rotating rod 72. A grinding wheel 4 is fixedly connected to the bottom of the bolt 73. Two sets of limiting grooves 74 are opened on the upper and lower surfaces of the rotating rod 72. Two sets of self-locking nuts 75 are threadedly connected to the bolt 73 at the upper and lower ends of the rotating rod 72. A guide rail 76 is provided on the right end surface of the fixed base 71. A rotating ring 77 is fixedly connected to the right end of the rotating rod 72. The rotating ring 77 is rotatably connected to the guide rail 76. A threaded rod 78 is threadedly connected inside the guide rail 76. Multiple sets of threaded grooves 79 are opened inside the rotating ring 77. The guide rail 76 is threadedly connected to the threaded grooves 79 through the threaded rod 78.

[0023] The threaded rod 78 rotates within the threaded groove 79 and then exits from it. The rotating ring 77 then drives the rotating rod 72 to rotate within the fixed base 71, simultaneously aligning the threaded groove 79 on the rotating ring 77 with the threaded rod 78 until the grinding wheel 4 is adjusted to the desired angle. Finally, the threaded rod 78 is threaded into the threaded groove 79, thus adjusting the angle of the grinding wheel 4. This allows the grinding wheel 4 to grind crystalline copper plates with different inner arc surfaces, thereby improving the adaptability of the device.

[0024] like Figure 4 As shown, the rotating ring 77 has a fan-shaped design and a through hole in the middle, which allows the operator to manually operate the rotating ring 77 so that the rotating ring 77 drives the rotating rod 72 to rotate in the fixed seat 71 and adjusts the angle of the grinding wheel 4.

[0025] like Figure 4 As shown, eight sets of threaded grooves 79 are provided, and all eight sets of threaded grooves 79 are designed with equal spacing. The rotating ring 77 drives the rotating rod 72 to rotate in the fixed seat 71, so that the rotating ring 77 rotates synchronously in the guide rail 76, and the multiple sets of threaded grooves 79 are aligned with the threaded rod 78 in sequence. Then, the threaded rod 78 rotates into the threaded grooves 79, thereby achieving the purpose of adjusting the eight working angles of the grinding wheel 4.

[0026] like Figure 1 and Figure 3 As shown, the surface of the processing platform 6 is provided with a protective component 8. The protective component 8 includes a movable chamber 81 set on the front surface of the processing platform 6. A bidirectional lead screw 82 is rotatably connected inside the movable chamber 81. A handle 83 is fixedly connected to the right end of the bidirectional lead screw 82. Two sets of transmission blocks 84 are threadedly connected to the bidirectional lead screw 82. A socket 85 is inserted into the top of the two sets of transmission blocks 84. A protective cover 86 is fixedly connected to the rear surface of the socket 85. The protective cover 86 is designed to be transparent. An extension plate 87 is fixedly connected to the right end of the protective cover 86 on the left side of the processing platform 6. An insertion slot 88 is opened at the left end of the insertion slot 88 on the right side of the processing platform 6. The extension plate 87 is slidably connected to the insertion slot 88.

[0027] The handle 83 drives the bidirectional lead screw 82 to rotate within the movable chamber 81, and the rotating bidirectional lead screw 82 acts on the transmission block 84, causing the transmission block 84 to drive the two sets of protective covers 86 to move on the processing platform 6 through the socket 85 and converge towards the center of the processing platform 6. At the same time, the extension plate 87 slides into the insertion slot 88 and forms a protective area to prevent the debris generated when the grinding wheel 4 grinds the crystallized copper plate from flying out and causing injury to the workers.

[0028] like Figure 3As shown, the transmission block 84 is designed in a T-shape, and the movable chamber 81 has a through hole that matches the transmission block 84, so that the movable chamber 81 can guide the movement of the transmission block 84, so that the transmission block 84 can make linear reciprocating motion within the movable chamber 81.

[0029] like Figure 1 As shown, the handle 83 is designed to be hand-cranked, and the surface of the handle 83 is provided with anti-slip texture, which makes it easier for the operator to rotate the bidirectional lead screw 82 through the handle 83, making it easier to rotate the bidirectional lead screw 82.

[0030] This utility model provides a grinding device for strengthening the inner arc surface of a continuously cast crystalline copper plate. The specific working principle is as follows: In use, first, the crystalline copper plate is placed on the processing platform 6. Then, the bolt 73 is slid into the rotating rod 72. Two sets of self-locking nuts 75 rotate the bolt 73 threadedly, fixing the grinding wheel 4 onto the rotating rod 72. Next, the threaded rod 78 is rotated, causing it to rotate threadedly within the guide rail 76 and exit the threaded groove 79. Then, the rotating ring 77 is rotated, causing the rotating ring 77 to rotate out of the threaded groove 79. The rotating rod 72 is driven to rotate within the fixed seat 71, and the grinding wheel 4 is rotated to the required angle. At this time, any set of thread grooves 79 is aligned with the thread rod 78. Then, the processing platform 6 is lifted by the cylinder 5, and the grinding wheel 4 is brought into contact with the inner arc surface of the crystallized copper plate. Then, the thread rod 78 is rotated into the thread groove 79, thereby achieving the purpose of adjusting the angle of the grinding wheel 4. Then, the grinding wheel 4 is driven to rotate by the drive motor 3, and the drive motor 3 is moved back and forth and left and right by the transmission mechanism 2. This completes the process.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
