Description

Technical Field

[0001] The invention relates to the technical field of nozzle brick production, in particular to a device for preparing high-strength ladle nozzle bricks. Background Art

[0002] The nozzle brick is a refractory steel outlet embedded in the base brick at the bottom of the steel ladle. When not pouring, the nozzle brick and the plug brick are in linear contact to ensure that there is no steel leakage. The upper mouth of the nozzle brick is an arc-shaped surface, which is convenient for opening and closing the nozzle and reducing the resistance to the flow of molten steel. The lower section is a straight section to stabilize the injection flow. When producing conical nozzle bricks, the material needs to be extruded and formed through two molds, and then dried and shaped through a series of equipment, so that it is convenient to be embedded in the ladle for molten steel.

[0041] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the moving mechanism 4 includes a support frame 401, one end of the support frame 401 is connected to both sides of the hydraulic press 1 through a slot 403, one side of the hydraulic press 1 is connected to the support frame 401, one end of the support frame 401 is connected to both sides of the hydraulic press 1 through the slot 403, a mounting frame 402 is provided on the top of the support frame 401, a plurality of sliders 406 are respectively installed at the bottom of both ends of the mounting frame 402, parallel guide rails 405 are respectively installed on both sides of the top of the support frame 401, the sliders 406 are slidably connected to the guide rails 405, the mounting frame 402 is slidably connected to the support frame 401 through the cooperation of the sliders 406 and the guide rails 405, two vertical plates 409 are vertically connected at the center line of the top of the support frame 401, a screw rod 408 is rotatably connected between the two vertical plates 409, a servo motor 407 is installed on the outer side of one of the vertical plates 409, One end of the screw rod 408 is connected to the output shaft of the servo motor 407, and a drive plate 404 is threadedly connected to the screw rod 408. The drive plate 404 is an "n"-shaped structure. The bottoms of both ends of the drive plate 404 are connected to the two sides of the mounting frame 402. The installation of the support frame 401 is conducive to supporting the mounting frame 402. With the cooperation of the slider 406 and the guide rail 405, the mounting frame 402 and the top of the support frame 401 can slide freely. The installation of the screw rod 408 is conducive to the connection of the drive plate 404. Through the connection between the drive plate 404 and the mounting frame 402, the screw rod 408 is driven to rotate when the servo motor 407 is working, and the screw rod 408 controls the movement of the drive plate 404, thereby realizing precise control of the moving position of the mounting frame 402, which is conducive to subsequent loading and unloading operations.

[0042] Specifically, Figure 1 , Figure 6 , Figure 8 and Fig. 9As shown, the feeding mechanism 5 includes a material guide pipe 502, the material guide pipe 502 is fixedly connected at the top center line of the mounting frame 402, the material guide pipe 502 is a "convex" shaped structure with a hollow interior, a material guide disc 503 is installed at one end of the material guide pipe 502, a material scattering disc 505 is installed at the bottom center of the material guide disc 503, the material scattering disc 505 is a funnel-shaped structure, the inner diameter of the material scattering disc 505 is larger than the outer diameter of the upper mold 201, a storage hopper 501 is installed at the top center of the material guide pipe 502, a push block 506 is slidably connected inside the material guide pipe 502, and the push block 506 is located at the bottom of the storage hopper 501, and a cylinder 507 is installed at the other end of the material guide pipe 502, and the output shaft at one end of the cylinder 507 extends to the inside of the material guide pipe 502 and is connected to the push block 506. 2 is installed to facilitate the transportation of materials. The installation of the storage hopper 501 is installed to facilitate the storage of materials. The materials enter the top of the guide tube 502 through the storage hopper 501. When the materials are moved to the side of the hydraulic press 1 through the mounting frame 402, the materials cannot be discharged due to the resistance of the push block 506. The operation of the cylinder 507 causes the push block 506 to shrink, and the materials are introduced into the front end of the push block 506. The cylinder 507 operates again to move the push block 506 to push the materials out. The cylinder 507 operates repeatedly to repeatedly move the push block 506, thereby realizing the discharge and pushing of the materials. Finally, the materials enter the guide plate 503 and the spreading plate 505. The materials enter the lower mold 202 through the spreading plate 505 for feeding and extrusion molding.

A protective plate 601 is installed on the top of the column 602. The bottom of the scattering tray 505 is slidably connected to the top side of the protective plate 601. The installation of the column 602 realizes the support connection of the protective plate 601, thereby shielding and protecting the scattering tray 505 to prevent material from being scattered. Only when the scattering tray 505 moves to the top of the lower mold 202, the material can fall and be loaded.

[0045] Specifically, Figure 6 and Fig.10 As shown, the unloading mechanism 7 includes a fixed plate 702, a fixed plate 702 is installed on the guide disc 503, a mounting block 703 is installed on the fixed plate 702, a hydraulic cylinder 704 is installed on the mounting block 703, and sliding rods 705 are respectively provided at both ends of the fixed plate 702, and both ends of the sliding rod 705 are fixedly connected to the fixed plate 702 and the guide disc 503 through a supporting block 76, a slide plate 707 is provided between the two sliding rods 705, and both ends of the slide plate 707 are slidably connected to the two sliding rods 705, and the slide plate 707 is a "T"-shaped structure, and two symmetrical clamping plates 701 are rotatably connected to the slide plate 707, and a telescopic spring 708 is connected between the two clamping plates 701, and the other end of the clamping plate 701 is an arc structure. The output shaft at the bottom of the hydraulic cylinder 704 is connected to the center of the top of the slide plate 707. After the material is extruded and formed, it is ejected, and the mounting frame 402 drives the guide plate 503 to move to a certain position, and the two clamping plates 701 installed on the guide plate 503 follow the movement. After moving to a certain position, the two clamping plates 701, with the cooperation of the telescopic spring 708, clamp the finished material, and then the hydraulic cylinder 704 works to lift the slide plate 707. With the cooperation of the slide bar 705, the slide plate 707 slides smoothly, so that the formed material is lifted out of the lower mold 202, and the mounting frame 402 moves again, so that the lifted material is transported to one end for safe removal.

[0046] Specifically, Figure 8 and Fig.11As shown, the shaking mechanism 8 includes a fixed sleeve 803, a fixed sleeve 803 is installed on the bottom side of the storage hopper 501, the fixed sleeve 803 is a "M"-shaped structure, a top rod 804 is vertically connected to the center of the fixed sleeve 803, the bottom of the top rod 804 is slidably connected to the inside of the fixed sleeve 803 through a compression spring 806, the bottom of the top rod 804 extends to the outside of the bottom of the fixed sleeve 803, the bottom of the top rod 804 extends to the top of the push block 506, a fixed seat 801 is installed on the bottom of the top rod 804, a guide wheel 802 is rotatably connected to the fixed seat 801, the guide wheel 802 is in conflict with the push block 506, and the top rod A plurality of push rods 805 are installed on the top side wall of 804. Through the resistance of the compression spring 806, the push rod 804 is always kept in resistance downward, and the guide wheel 802 at the bottom of the push rod 804 is in resistance with the push block 506. When the push block 506 is loaded, it shrinks, and the guide wheel 802 has no external force resistance. The push rod 804 slides down. When pushed by the push block 506, the push block 506 resists the guide wheel 802 and rises, so that the push rod 804 rises. The push block 506 slides back and forth, so that the push rod 804 shakes back and forth up and down, so as to guide the bottom of the storage hopper 501 and make the material discharge smoothly.

[0047] When the present invention is in use, firstly, the upper mold 201, the lower mold 202 and the hydraulic press 1 are installed in coordination to realize the extrusion molding production of the nozzle bricks. The molded nozzle bricks slide out under the drive of the top material cylinder 203, which is convenient for unloading. The installation of the receiving tray 305 is conducive to collecting and storing the materials scattered during the loading or extrusion molding of the lower mold 202, and introducing them into the inside of the discharge pipe 301 through the discharge trough 302, and then exporting and recovering them through the discharge pipe 301, so that the residual materials can be well cleaned and the operation is more convenient. By pushing the scraper 303, the scraper 303 drives the rotating sleeve 306 to rotate, so that the multiple scrapers 303 on the rotating sleeve 306 can push the materials in the docking tray 305, so that the materials can be pushed into the discharge trough 302 and exported Recycling, the installation of the cover plate is conducive to shielding and protecting the rotating sleeve 306, preventing the rotating sleeve 306 from separating from the lower mold 202 when rotating, and the removal of the top cover 304 facilitates the disassembly and maintenance of the rotating sleeve 306. The opening of the groove 307 facilitates the holding and pushing of the scraper 303. The installation of the support frame 401 facilitates the support of the mounting frame 402. With the cooperation of the slider 406 and the guide rail 405, the mounting frame 402 and the top of the support frame 401 can slide freely. The installation of the screw rod 408 facilitates the connection with the drive plate 404. Through the connection between the drive plate 404 and the mounting frame 402, when the servo motor 407 is working, the screw rod 408 is driven to rotate, and the screw rod 408 controls the movement of the drive plate 404, thereby realizing the movement position of the mounting frame 402 Precise control is beneficial to the subsequent loading and unloading operations. The installation of the guide pipe 502 is beneficial to the transportation of materials. The installation of the storage hopper 501 is beneficial to the storage of materials. The materials enter the top of the guide pipe 502 through the storage hopper 501. When the materials are moved to the side of the hydraulic press 1 through the mounting frame 402, the materials cannot be unloaded due to the resistance of the push block 506. The push block 506 is contracted by the operation of the cylinder 507, and the materials are introduced into the front end of the push block 506. The push block 506 is moved to push the materials out by the operation of the cylinder 507 again. The push block 506 is repeatedly moved by the repeated operation of the cylinder 507, thereby realizing the unloading and pushing out of the materials. Finally, the materials enter the guide plate 503 and the scattering plate 505, and the materials are introduced into the scattering plate 505. The material is fed into the lower mold 202 for extrusion molding. The installation of the baffle 508 is conducive to shielding the pushed out material, so that the material can be introduced into the two sides of the baffle 508. The baffle 508 is provided with a through groove 509, so that part of the material can be discharged, so that the material can be diverted around the guide plate 503, so that the material discharge is more uniform. The installation of the column 602 realizes the support connection of the protective plate 601, thereby shielding and protecting the scattering plate 505 to prevent the material from being scattered. The material can only fall and load when the scattering plate 505 moves to the top of the lower mold 202. After the material is extruded and molded, it is ejected. The mounting frame 402 drives the guide plate 503 to move to a certain position, and the two clamping plates 701 installed on the guide plate 503 follow the movement. When it moves to a certain position,The two clamping plates 701, in cooperation with the telescopic spring 708, clamp the finished material, and then the slide plate 707 is lifted by the operation of the hydraulic cylinder 704. In cooperation with the slide bar 705, the slide plate 707 slides smoothly, so that the formed material is lifted out of the lower mold 202. The lifting material is transported to one end by the movement of the mounting frame 402 again, so that it is easy to take out safely. Under the resistance of the compression spring 806, the top rod 804 is always kept in resistance downward, and the guide wheel 802 at the bottom of the top rod 804 is in resistance with the push block 506. When the push block 506 is loaded, the guide wheel 802 is not in resistance with external force, and the top rod 804 slides down. When pushed by the push block 506, the push block 506 resists the guide wheel 802 and rises, so that the top rod 804 rises.
