Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnesia-carbon brick production technology, specifically to a brick blank forming device for magnesia-carbon brick production. Background Technology
[0002] Magnesia-carbon bricks possess excellent high-temperature resistance and are primarily used as linings for converters, AC electric arc furnaces, and DC electric arc furnaces. As a composite refractory material, magnesia-carbon bricks are made from magnesium oxide and carbon materials as raw materials, with various non-oxide additives added, and bonded together with a carbonaceous binder. The preparation of magnesia-carbon bricks requires pressing the raw materials into shape. The production method for magnesia-carbon brick blanks often involves extruding the raw materials using extrusion blocks. However, after extruding a magnesia-carbon brick, the extrusion block easily retains raw materials from the previous batch. If the next magnesia-carbon brick is directly extruded, mixing can easily occur, affecting the pressing of the next batch of magnesia-carbon brick blanks. To improve this situation, a brick blank forming device for magnesia-carbon brick production is proposed.
[0003] For example, the brick blank forming machine for producing magnesia-carbon bricks disclosed in the authorization announcement number CN221604671U includes a processing table, a conveying plate provided on the processing table through a conveying mechanism, a forming component provided on the conveying plate through an adjusting component, a pressing component matching the forming component on the processing table, and a cleaning and collection mechanism matching the pressing component on the conveying plate.
[0004] Although it allows for the timely cleaning and collection of raw materials adhering to the surface after the pressing components have been processed and used, it does not affect the next processing and can also prevent the materials from adhering to the surface and affecting the flatness of the next pressing. In addition, it can also collect the raw materials for easy recycling and reuse.
[0005] However, the existing brick forming equipment does not solve the problems of inconvenient demolding and removal of extruded magnesia-carbon bricks, nor the problem of moving and sweeping away the raw materials adhering to the bottom of the compact. This hinders the continuous input and extrusion forming of magnesia-carbon bricks and affects the convenience of cleaning up adhering raw materials and demolding magnesia-carbon bricks. Utility Model Content
[0006] The purpose of this utility model is to provide a brick blank forming device for the production of magnesia-carbon bricks, so as to solve the problems mentioned in the background art, which are not convenient for demolding and removing the extruded magnesia-carbon bricks and for moving and sweeping the raw materials adhering to the bottom of the pressing block. This is not conducive to the continuous input and extrusion molding process of magnesia-carbon bricks, and affects the convenience of cleaning the adhering raw materials and demolding the magnesia-carbon bricks.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a brick blank forming device for magnesia-carbon brick production, comprising a worktable and a transverse screw drive mechanism. The top of the worktable is provided with the transverse screw drive mechanism. A support frame is provided on the top of the worktable on one side of the transverse screw drive mechanism. A pressure table is provided on the top of the worktable on one side of the support frame. A longitudinal screw drive mechanism is provided at the power output end of the transverse screw drive mechanism. A placement block is provided at the power output end of the longitudinal screw drive mechanism. A second servo motor is provided on the side wall of the placement block, and a cleaning roller is installed at the output end of the second servo motor. An L-shaped frame is provided at the top of the support frame, and a hydraulic cylinder is installed at the top of the L-shaped frame. A first push arm is installed at the output end of the hydraulic cylinder, and a pressure block is provided at the bottom end of the first push arm. A drive seat is provided inside the worktable. Two sets of cylinders are provided inside the worktable on one side of the drive seat. A second push arm is installed at the output end of each cylinder, and a top block is installed at the top end of each second push arm.
[0008] Preferably, a first servo motor is provided on the side wall of the drive base, and a worm gear is installed at the output end of the first servo motor, and the worm gear is movably connected to the drive base.
[0009] Preferably, a drive shaft is movably disposed inside the drive seat on one side of the worm gear, and the drive shaft extends to the outside of the worktable and is movably connected to the worktable.
[0010] Preferably, a worm gear is fitted onto the surface of the drive shaft, and the worm gear meshes with the worm.
[0011] Preferably, a rotating disk is mounted on the top end of the drive shaft, and the rotating disk is slidably connected to the pressure table.
[0012] Preferably, the top of the rotating disk is provided with multiple sets of equally spaced through slots, and limit posts are provided on the top of the rotating disk on both sides of the through slots.
[0013] Preferably, multiple sets of molds with equal spacing are arranged above the rotating disk, and the bottom end of each mold is symmetrically provided with a limiting groove, and the top block can pass through the through groove and be inserted into the inside of the limiting groove.
[0014] Preferably, pin holes are provided at the bottom of the mold on both sides of the limiting groove, and the limiting pin can be inserted into the inside of the pin holes.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the brick forming equipment not only realizes convenient demolding and removal of the extruded magnesia-carbon bricks and the moving and rolling cleaning of the raw materials adhering to the bottom of the pressing block, facilitating the continuous input and extrusion forming process of magnesia-carbon bricks, but also improves the convenience of cleaning the adhering raw materials and demolding the magnesia-carbon bricks.
[0016] (1) The first servo motor drives the worm gear to rotate, the worm gear drives the drive shaft to rotate through the worm wheel, and the drive shaft drives the rotating disk and the mold to rotate, so that the mold with the raw material is placed on it rotates to the top of the pressure table. The pressure table provides support for the rotating disk. The hydraulic cylinder drives the pressure block to move downward through the first push arm. The pressure block extrudes and forms the raw material. The mold limits the raw material. After the magnesia-carbon brick is extruded and formed, the pressure block is reset. The transverse screw drive mechanism drives the first servo motor and the placement block to move laterally. The placement block drives the cleaning roller to move to the bottom of the pressure block. The second servo motor drives the cleaning roller to rotate. The cleaning roller rolls and cleans the raw material adhering to the bottom of the pressure block. The longitudinal screw drive mechanism drives the cleaning roller to move longitudinally through the placement block. The cleaning roller rolls and cleans the bottom of the pressure block longitudinally to clean the raw material adhering to the bottom of the pressure block, so as to avoid the raw material affecting the production of the next magnesia-carbon brick. This realizes the movement and rolling cleaning of the raw material adhering to the bottom of the pressure block, and improves the convenience of cleaning the adhering raw material.
[0017] (2) The magnesia-carbon brick and the corresponding mold, which are extruded and formed, continue to rotate with the rotating disk. When the disk rotates to the top block, it stops rotating. The cylinder drives the top block to move upward through the second push arm. The top block passes through the inside of the through slot and inserts into the inside of the limiting slot. The top block drives the mold to move upward, so that the mold is separated from the magnesia-carbon brick, thus realizing the demolding work. After that, the magnesia-carbon brick can be removed manually. After the magnesia-carbon brick is removed, the cylinder is opened in the opposite direction. The cylinder drives the second push arm and the top block to reset. Under the action of gravity, the mold falls and lands on the surface of the rotating disk, so that the limiting post is inserted into the pin hole to limit and fix the mold. Then the mold continues to rotate with the rotating disk. The raw material is placed again and the above operation is repeated to continuously input and extrude the magnesia-carbon brick. This realizes the convenient demolding and removal of the extruded magnesia-carbon brick, which facilitates the continuous input and extrusion processing of magnesia-carbon brick and improves the convenience of demolding.

[0030] The raw material is poured into the mold 7. The first servo motor 9 is turned on, which drives the worm gear 10 to rotate. Under the meshing of the worm gear 10 and the worm wheel 11, the worm gear 10 drives the drive shaft 13 to rotate through the worm wheel 11. The drive shaft 13 drives the rotating disk 6 and the mold 7 to rotate, so that the mold 7 containing the raw material rotates to above the pressure table 26. The pressure table 26 provides support for the rotating disk 6. The hydraulic cylinder 4 is turned on, and the hydraulic cylinder 4 drives the pressure block 5 to move downward through the first push arm 14. The pressure block 5 extrudes and shapes the raw material, and the mold 7 limits the shape of the raw material. After the magnesia-carbon brick is extruded and shaped, the pressure block 5 returns to its original position. Then, the transverse screw drive mechanism 3 is turned on, which drives the first servo motor 9 to rotate. The servo motor 9 and the placement block 17 move laterally, and the placement block 17 drives the cleaning roller 16 to move to below the pressing block 5. The second servo motor 18 is turned on, and the second servo motor 18 drives the cleaning roller 16 to rotate.

[0033] The top of the rotating disk 6 is provided with multiple sets of through slots 25 at equal intervals.

The top block 21 passes through the inside of the through groove 25 and inserts into the inside of the limiting groove 23. The top block 21 drives the mold 7 upward, causing the mold 7 to detach from the magnesia-carbon brick, thus achieving demolding. Afterward, the magnesia-carbon brick can be removed manually. After the magnesia-carbon brick is removed, the cylinder 8 is opened in the reverse direction, and... The cylinder 8 drives the second push arm 20 and the top block 21 to reset. Under the action of gravity, the mold 7 falls and lands on the surface of the rotating disk 6, so that the limiting post 24 is inserted into the pin hole 22 to limit and fix the mold 7. Then the mold 7 continues to rotate with the rotating disk 6, the raw material is replaced and the above operation is repeated to continuously input and extrude the magnesia-carbon bricks.

[0036] Work steps
[0037] The raw material is poured into the mold 7. The first servo motor 9 drives the worm gear 10 to rotate, which in turn drives the drive shaft 13 via the worm wheel 11. The drive shaft 13 drives the rotating disk 6 and the mold 7 to rotate, so that the mold 7 containing the raw material rotates above the pressure table 26. The pressure table 26 provides support for the rotating disk 6. The hydraulic cylinder 4 drives the pressure block 5 to move downward via the first push arm 14. The pressure block 5 extrudes and shapes the raw material, and the mold 7 limits the material. After the magnesia-carbon brick is extruded and shaped, the pressure block 5 returns to its original position. The transverse screw drive mechanism 3 drives the first servo motor 9 and the placement block 17 to move laterally. The placement block 17 drives the cleaning roller 16 to move below the pressure block 5. The second servo motor 18 drives the cleaning roller 16 to rotate, and the cleaning roller 16 rolls and cleans the raw material adhering to the bottom of the pressure block 5. The longitudinal screw drive mechanism 19 drives the cleaning roller 16 to move longitudinally via the placement block 17, and the cleaning roller 16 rolls and cleans the bottom of the pressure block 5. The process involves cleaning the bottom of the pressing block 5 to remove any adhering raw material, preventing it from affecting the production of the next magnesia-carbon brick. The extruded magnesia-carbon brick and its corresponding mold 7 continue to rotate with the rotating disk 6. When the mold reaches above the top block 21, the rotating disk 6 stops rotating. The cylinder 8, through the second push arm 20, moves the top block 21 upward. The top block 21 passes through the inside of the through groove 25 and inserts into the inside of the limiting groove 23. The top block 21 then moves the mold 7 upward, causing it to detach from the magnesia-carbon brick, thus achieving demolding. The magnesia-carbon brick can then be removed manually. After the magnesia-carbon brick is removed, the cylinder 8 is opened in the reverse direction, causing the second push arm 20 and the top block 21 to reset. Under the influence of gravity, the mold 7 falls and lands on the surface of the rotating disk 6, allowing the limiting post 24 to insert into the pin hole 22 to limit and fix the mold 7. The mold 7 then continues to rotate with the rotating disk 6, and the raw material is repositioned. The above operation is repeated to continuously input and extrude the magnesia-carbon brick.
