Description

Technical Field

[0001] This utility model relates to the field of ceramic roll technology, and in particular to a wear-resistant ceramic roll structure. Background Technology

[0002] In the hot and cold rolling production lines of the steel industry, ceramic rolls can be used to roll various types of steel, such as stainless steel and high-silicon steel. Due to their extremely high hardness, wear resistance and corrosion resistance, they can withstand the high pressure, high temperature and severe friction during the rolling process, reduce roll wear, improve rolling accuracy, make the steel surface smoother and have higher dimensional accuracy.

[0003] Traditional ceramic rolls are usually installed on the rolling mill using methods such as interference fit, key connection or bolt fastening. The interference fit method relies on the interference between the roll and the shaft to generate friction to transmit torque. Although the connection is stable, it requires auxiliary equipment such as heating, cooling or press during disassembly and assembly. The operation is complicated and can easily damage the ceramic roll. In particular, ceramic materials are brittle and are very easy to crack or even break when subjected to external impact during disassembly and assembly.

[0004] In response to the technical problem that ceramic rolls are easily damaged during installation, this application proposes a wear-resistant ceramic roll structure. Utility Model Content

A wear-resistant ceramic roller structure is proposed, in which the roller body is inserted into the mounting cylinders on both sides during installation. The sliding cylinder is pushed and the knob is rotated, causing the four-sided extrusion blocks to press and limit the inner wall of the roller body. This ensures the extrusion blocks are evenly attached to the inner wall of the roller body, resulting in uniform force distribution and preventing damage to the ceramic components. The operation is simple.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Furthermore, the buckle assembly includes a main rotating rod rotatably connected to the inner wall of the slide cylinder, and each of the inner walls of the main rotating rod is rotatably connected to a pressing block, and each of the pressing blocks is rotatably connected to a secondary rotating rod at the other end.

[0009] Furthermore, each of the inner walls of the slide is rotatably connected to a knob, and each knob is fixedly connected to a threaded rod at one end.

[0010] Furthermore, each of the threaded rods has a transmission rod threadedly connected to its outer wall, and the outer wall of each transmission rod is slidably connected to the inner wall of the slide cylinder. The other end of each of the auxiliary rotating rods is rotatably connected to the inner wall of the transmission rod.

[0011] Furthermore, the caliper assembly includes a connecting frame fixedly connected to one inward end of the ceramic plate, and the inner wall of the connecting frame is provided with a caliper groove.

[0012] Furthermore, a locking block is provided on the inner wall of the slot, the shape of the locking block is matched with the slot, and the right end of the locking block is fixedly connected to the left end of the pull rod.

[0013] Furthermore, the inner wall of the pull rod is provided with a threaded rod II, the inner wall of the roll body is provided with a threaded groove, and the outer wall of the threaded rod II is provided on the inner wall of the threaded groove.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-3 As shown, one embodiment of this utility model provides a wear-resistant ceramic roll structure, including a roll body 1. Mounting cylinders 2 are provided at both ends of the roll body 1. Slide cylinders 3 are slidably connected to the inner walls of the mounting cylinders 2. Multiple main rotating rods 7 are rotatably connected to the inner walls of the slide cylinders 3. Extrusion blocks 8 are rotatably connected to the inner walls of the main rotating rods 7. A secondary rotating rod 9 is rotatably connected to the other end of each extrusion block 8. A knob 4 is rotatably connected to the inner wall of each slide cylinder 3. A threaded rod 5 is fixedly connected to one inward end of each knob 4. A transmission rod 6 is threadedly connected to the outer wall of each threaded rod 5. The outer wall of each transmission rod 6 is slidably connected to the inner wall of the slide cylinder 3. The other end of each secondary rotating rod 9 is rotatably connected to the inner wall of the transmission rod 6 for the assembly and disassembly of the roll body 1.

[0028] Specifically, the ceramic sheet 13 is made of silicon carbide ceramic, which has good thermal conductivity and good wear resistance, and is suitable for high temperature and high load conditions. The mounting cylinder 2 is rotatably connected to the fixed frame used to place the roll. During installation, the roll body 1 is inserted into the mounting cylinders 2 on both sides, and the sliding cylinder 3 is pushed and the knob 4 is rotated to drive the extrusion blocks 8 on the four sides to extrude and limit the inner wall of the roll body 1. This makes the extrusion blocks 8 evenly fit against the inner wall of the roll body 1, and the force is evenly distributed, avoiding damage to the ceramic parts. The operation is simple.

[0029] Reference Figure 4As shown, a pull rod 10 is slidably connected to the inner wall of the roll body 1. Multiple ceramic pieces 13 are arranged on the outer wall of the pull rod 10. A connecting frame 14 is fixedly connected to one inward end of each ceramic piece 13. A slot 15 is provided on the inner wall of each connecting frame 14. A locking block 12 is provided on the inner wall of the slot 15, and the shape of the locking block 12 matches the slot 15. The right end of the locking block 12 is fixedly connected to the left end of the pull rod 10. A threaded rod 11 is provided on the inner wall of the pull rod 10. A threaded groove is provided on the inner wall of the roll body 1. The outer wall of the threaded rod 11 is located on the inner wall of the threaded groove. A through hole is provided on the inner wall of the roll body 1. The shape of the connecting frame 14 matches the through hole for the assembly and disassembly of the ceramic pieces 13.

[0030] Specifically, during installation, first insert the connecting frame 14 inside the new ceramic plate 13 into the through hole. After installation, push the pull rod 10 to the left to insert the locking block 12 into the locking groove 15, and rotate the threaded rod 11 to rotate it into the threaded groove. This completes the installation. With the detachable ceramic plate 13, when the ceramic plate 13 is damaged, it can be removed and replaced separately, avoiding overall scrapping, reducing maintenance costs, and reducing replacement time and downtime.

[0031] Working principle: First, when installing the roll body 1, insert the roll body 1 into the mounting cylinders 2 on both sides, and push the sliding cylinder 3 inward to insert it into both sides of the roll body 1. Then, turn the knob 4. The knob 4 drives the threaded rod 5 to rotate, which in turn drives the transmission rod 6 to slide inward and rotates the auxiliary rotating rod 9. This causes the four pressing blocks 8 on all sides to flip outward, pressing and limiting the inner wall of the roll body 1 on all four sides, thus completing the installation. Second, when disassembly is required, simply turn the knob 4 in the opposite direction to slide the transmission rods 6 on both sides outward and rotate the pressing blocks 8 in the opposite direction to release the pressure on the roll body 1, allowing it to be removed. At the same time, when one side of the ceramic sheet 13 is damaged, first turn the threaded rod 11 to rotate it out of the threaded groove, and then pull the pull rod 10 to the right to remove the locking block 12 from the locking groove 15. This allows the ceramic sheet 13 to be removed from the roll body 1 for easy replacement.
