Description

Technical Field

[0001] This utility model relates to the field of metal casting equipment technology, and in particular to a quick-release continuous casting pouring nozzle structure. Background Technology

[0002] In modern metal industry, continuous casting is a key high-efficiency production process. It involves continuously pouring molten metal into a crystallizer through specific pouring equipment to solidify and form a cast billet. In this process, the pouring nozzle, which is in direct contact with the high-temperature molten metal, is a critical and easily damaged component that needs to be replaced periodically depending on production conditions or after wear and tear.

[0003] Currently, traditional casting nozzles are mostly fastened to the connecting mold or tundish equipment with multiple sets of bolts. Although this fixing method is reliable, it has revealed obvious shortcomings in actual production. Due to the extremely high ambient temperature in continuous casting sites, the bolts are prone to seizing due to thermal expansion and contraction, making disassembly very difficult and requiring a lot of manpower and time. The long downtime for replacement directly interrupts the continuity of production, seriously affecting the overall production rhythm and equipment utilization rate, and reducing economic benefits.

[0004] Therefore, this utility model proposes a quick-release continuous casting spout structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of cumbersome and time-consuming disassembly and assembly process, which seriously affects the continuity of production, and insufficient accuracy of pouring flow control, which affects the quality of cast billets, the present invention aims to provide a quick-disassembly continuous casting pouring nozzle structure with improved structure that can effectively solve the above problems.

[0006] This utility model provides a quick-release continuous casting spout structure, including: a support plate, a connecting mold fixedly connected to the top of the support plate, and a casting body detachably installed on the top of the connecting mold; the structure also includes an adjustment mechanism disposed on the support plate.

[0007] The top of the connecting mold is fixedly connected to a fixing block, and the two sides of the outer wall of the fixing block are fixedly connected to limit rods. The bottom of the casting body is fixedly connected to a connecting block, and the inner wall of the connecting block is provided with an installation groove. The two ends of the installation groove are provided with limit grooves that cooperate with the limit rods.

[0008] Furthermore, a first rotating shaft is rotatably connected to the inner wall of the mounting groove, and a protruding rod is fixedly connected to the outer wall of the first rotating shaft. The protruding rod is adapted to abut against the limiting rod when the first rotating shaft rotates to lock the casting body onto the connecting mold. The adjusting mechanism includes a connecting rod fixed to the top of the support plate, an injection tube passing through the connecting rod, and a funnel fixed to the bottom of the injection tube. The outlet of the funnel is located above the casting body and is used to deliver fluid into the casting body. This combination of quick-release locking structure and adjusting mechanism enables quick replacement of the casting nozzle and control of the flow rate.

[0009] Preferably, the casting body has a guide groove inside, and the outlet of the funnel is aligned with the inlet of the guide groove. This structural design can ensure that the high-temperature fluid flowing out of the funnel is stably and centrally guided to the predetermined path, effectively avoiding fluid splashing and turbulence.

[0010] Preferably, when the mounting slot and the fixing block are assembled, the limiting rod on the fixing block first slides into the limiting groove of the mounting slot. This pre-positioning structure reduces the difficulty of installation alignment, and the operator can quickly place the casting body in the correct position without repeated adjustments, which facilitates the subsequent locking operation.

[0011] Preferably, the protruding rod has a profile eccentric to the axis of the first rotating shaft. When the first rotating shaft rotates to the locked position, the farthest point of the protruding rod's profile can abut against the limiting rod. By utilizing the cam force amplification principle, a huge locking force is generated with a small operating force, ensuring the fastening reliability of the connection.

[0012] Preferably, the adjustment mechanism also includes a motor installed at the top of the connecting rod, a second rotating shaft driven by the motor, and an adjustment plate fixedly connected to the end of the second rotating shaft and placed inside the injection tube. This electronic control adjustment system realizes remote and automated control, improving the response speed and accuracy of process adjustment.

[0013] Preferably, the adjusting plate is a sheet-like structure. The motor drives the sheet-like adjusting plate to rotate at different angles inside the injection tube through the second rotating shaft, thereby linearly changing the flow cross-sectional area of ​​the fluid and realizing continuous and smooth adjustment of the pouring flow rate.

[0014] Preferably, a limiting ring is provided between the outer wall of the injection tube and the inner wall of the connecting rod. The limiting ring is used to axially limit the injection tube, which can effectively prevent the injection tube from axially displacing under the impact of high-temperature fluid or equipment vibration, thus ensuring the structural stability of the adjustment mechanism.

[0015] Preferably, the connecting block and the casting body are integrally formed, and the fixing block and the connecting mold are integrally formed. The integrated design reduces the number of connections and enhances the overall rigidity and durability of the structure. Especially under harsh working conditions of high temperature and heavy load, it can better maintain the stability of the structure.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of cumbersome and time-consuming disassembly and assembly of the pouring nozzle in the prior art by setting a quick-release locking mechanism composed of a fixing block, a connecting block, a limiting rod, a limiting groove, a first rotating shaft, and a protruding rod. It achieves the technical effects of quick installation and disassembly of the pouring nozzle, shortening the replacement time, and significantly improving the efficiency of continuous production.

[0017] 2. This utility model integrates the quick-release locking structure with the flow regulation mechanism into one unit. The overall structure is compact and the functions are clear. It not only improves the ease of operation and production efficiency, but also optimizes the casting process through flow control, thus possessing the dual advantages of high efficiency and high quality.

[0022] Please refer to Figure 1 and Figure 4 To achieve locking, a first rotating shaft 11 is rotatably connected to the inner wall of the mounting groove 8, and a protruding rod 12 is fixedly connected to the outer wall of the first rotating shaft 11. After the initial alignment is completed, the first rotating shaft 11 is rotated, which drives the protruding rod 12 to rotate synchronously. After the protruding rod 12 rotates, its outline will abut against and press against the limiting rod 10, thereby firmly locking the casting body 4 onto the connecting mold 3.

[0023] Please refer to Figure 3 and Figure 4 As shown, the adjustment mechanism 2 includes a connecting rod 201 vertically fixed to the top of the support plate 1, an injection tube 202 passing through the connecting rod 201, and a funnel 203 fixed to the bottom of the injection tube 202; a motor 204 is installed at the top of the connecting rod 201, and a second rotating shaft 205 is fixedly connected to the output end of the motor 204. The second rotating shaft 205 extends downward and is fixedly connected to an adjustment plate 206, which is placed inside the injection tube 202; in addition, a limiting ring 207 is provided between the outer wall of the injection tube 202 and the inner wall of the connecting rod 201. The limiting ring 207 is used to axially limit the injection tube 202 to prevent it from moving or falling off.

[0024] Please refer to Figure 1 and Figure 3 The connecting block 7 at the bottom of the casting body 4 and the fixing block 6 at the top of the connecting mold 3 form a mating pair that can be quickly inserted and locked; wherein, the connecting block 7 and the casting body 4 are integrally formed structures, and the mounting groove 8 inside it has a contour that matches the shape of the fixing block 6; the two ends of the mounting groove 8 are respectively provided with limiting grooves 9 for accommodating the limiting rod 10. The fixing block 6 at the top of the connecting mold 3 is also integrally formed with the connecting mold 3, and the limiting rods 10 are firmly fixedly connected to both sides of its outer wall.

This structure ensures that the casting body 4 and the connecting mold 3 can achieve rapid and accurate axial and circumferential positioning before locking.

[0025] Please refer to Figure 1 and Figure 2 The key to the quick-release locking structure lies in the locking assembly located inside the mounting groove 8. The assembly includes a first rotating shaft 11 rotatably connected to the inner wall of the mounting groove 8, and a protruding rod 12 fixedly connected to the outer wall of the first rotating shaft 11. The protruding rod 12 has a profile eccentric to the axis of the first rotating shaft 11. When the first rotating shaft 11 is rotated, the protruding rod 12 rotates synchronously. When rotated to the locking position, the farthest point of the profile of the protruding rod 12 will abut against and press against the limiting rod 10, generating a strong locking force using the lever or cam principle, thereby fixing the entire casting body 4 tightly and without shaking onto the connecting mold 3. Reverse rotation of the first rotating shaft 11 can quickly release the lock, facilitating the replacement of the casting body 4.

[0026] As a preferred embodiment, in order to ensure that the casting fluid can be guided smoothly, please refer to... Figure 3 The casting body 4 has a U-shaped guide groove 5 inside; the outlet of the funnel 203 at the bottom of the adjusting mechanism 2 is aligned with the inlet end of the guide groove 5, so as to ensure that the high temperature fluid flowing out from the injection tube 202 can be concentrated and introduced into the guide groove 5 without splashing, and flow along the preset trajectory. As another preferred embodiment, in order to achieve effective control of the pouring flow rate, please refer to... Figure 3 and Figure 4 The regulating plate 206 in the regulating mechanism 2 is designed as a sheet structure, and its diameter matches the inner diameter of the injection tube 202. The motor 204 drives the regulating plate 206 to rotate around its central axis inside the injection tube 202 through the second rotating shaft 205. By changing the rotation angle of the regulating plate 206, the flow cross-sectional area of ​​the fluid in the injection tube 202 can be effectively changed, thereby realizing the regulation of the pouring flow rate. In another preferred embodiment, in order to ensure the stability of the connection between the components in the adjustment mechanism 2, a limiting ring 207 is provided between the outer wall of the injection tube 202 and the inner wall of the connecting rod 201. The limiting ring 207 is fixed to the inner wall of the connecting rod 201 by snap-fit ​​or welding, and cooperates with the annular flange on the outer wall of the injection tube 202, thereby providing a reliable axial limiting effect on the injection tube 202 and preventing it from moving downward or upward under equipment vibration or fluid impact.

[0027] Working principle: During installation, a connecting mold 3 is fixed to the top of the support plate 1, a fixing block 6 is set at the top of the connecting mold 3, a connecting block 7 is fixed to the bottom of the guide groove 5, and an installation groove 8 is provided on the inner wall of the connecting block 7. Therefore, the connecting block 7 is connected to the top of the outer wall of the fixing block 6 through the installation groove 8, which facilitates the installation of the casting body 4 and the connecting mold 3. Since the two ends of the installation groove 8 are provided with limit grooves 9, and the two sides of the outer wall of the fixing block 6 are fixed with limit rods 10, and the two ends of the installation groove 8 are rotated by a first rotating shaft 11, and the outer wall of the first rotating shaft 11 is fixedly connected with a protruding rod 12, when the fixing block 6 is connected to the installation groove 8, the limit rod 10 is connected to the inner wall of the limit groove 9. Then, the installation groove 8 is rotated, and the installation groove 8 is connected and fixed through the limit rod 10. Rotating the first rotating shaft 11 drives the protruding rod 12 to rotate to the outer wall of the limit rod 10, and the guide groove 5 can guide the work, thereby achieving the effect of rapid installation and improving production continuity. The adjusting mechanism 2 can adjust the flow rate. Since the top of the support plate 1 is provided with a connecting rod 201, and the inner wall of the connecting rod 201 is connected to the injection tube 202, and the bottom end of the injection tube 202 is fixed with a funnel 203, the injection tube 202 supported by the connecting rod 201 concentrates the flow to the inner wall of the funnel 203, so that it is injected into the inner wall of the guide groove 5 to start working. The top of the connecting rod 201 is provided with a motor 204, and the output end of the motor 204 is provided with a second rotating shaft 205. The outer wall of the second rotating shaft 205 is connected to an adjusting plate 206. Therefore, when the motor 204 is turned on, it causes the adjusting plate 206 to rotate on the inner wall of the injection tube 202 through the second rotating shaft 205, so that the flow rate can be adjusted by adjusting the adjusting plate 206 during flow. The limiting ring 207 causes the injection tube 202 to fall off when connected, thereby achieving the effect of adjusting the injection rate, ensuring the stability of the billet quality and reducing the defect rate.
