Description

Technical Field

[0001] This application relates to the technical field of rapid prototyping of bricks, and in particular to an energy-saving rapid prototyping equipment and process for refractory bricks. Background Technology

[0002] Refractory bricks are building materials composed of various aggregates and one or more binders. They have the characteristics of good heat insulation and high compressive strength. However, traditional refractory brick production and processes face problems: long-term high-temperature firing not only consumes a lot of energy, but may also cause the product to deform during the firing process, affecting the quality and stability of the finished product.

[0003] Therefore, improving the precision and efficiency of the manufacturing process is a pressing technical problem. For example, patent application CN120287408A discloses a composite mold forming equipment for refractory bricks, consisting of an upper mold, a lower mold, and side molds. These three components work together to perform multi-directional stamping on the brick body, achieving uniform forming, reducing density gradients and cracking, and improving quality. The equipment includes directional stamping parts and a lower stamping part, converting the downward pressure of the upper mold into side and bottom stamping pressure, completing all-around compaction. Fixed separation parts are provided between the side molds, automatically separating them during demolding to prevent brick adhesion, facilitate unloading, and prevent friction and wear between the brick and the mold, protecting the mold and further improving the quality of the finished product.

[0004] The aforementioned prior art does not uniformly distribute the raw material poured into the mold. The raw material will naturally form an irregular state of local accumulation or gaps in the mold cavity. As a result, in the subsequent process of the side mold extruding the raw material towards the center of the mold, this irregular distribution of raw material will directly lead to local blank areas in the mold cavity, making it difficult to avoid gaps between the side mold and the raw material.

[0005] As a result, the raw materials in the gap area cannot be subjected to sufficient extrusion pressure, making it difficult to achieve a tight bond between the material particles. On the other hand, even in the extruded area, the pressure relief effect of the surrounding gaps will lead to an uneven overall extrusion strength, and eventually, obvious pitting defects will appear on the surface of the extruded brick blank.

[0006] Furthermore, when the side mold begins to separate from the brick blank, the surface of the brick blank will adhere tightly to the inner wall of the side mold due to adhesiveness. As the side mold continues to separate, the brick blank body adhering to the side mold will generate tensile resistance, which will eventually easily lead to tearing and damage on the surface of the brick blank, forming irregular cracks or peeling areas on the surface of the brick blank. Summary of the Invention

[0007] To address the aforementioned technical problems, this application provides an energy-saving rapid prototyping equipment and process for refractory bricks, employing the following technical solution: In a first aspect, an energy-saving rapid prototyping equipment for refractory bricks includes a bottom frame, on which a plurality of forming frames are slidably arranged along its length, and a stamping mechanism is installed on the bottom frame, the stamping mechanism including a stamping frame and a stamping block installed at its bottom.

[0008] The forming frame has a through structure, with a sliding U-shaped frame on its inner side wall and a stamping base plate at the bottom.

[0009] The vertical movement of the stamping frame can drive the forming frame to perform vertical reciprocating motion during the stamping process.

[0010] Preferably, a rotating shaft is provided on the bottom frame, a plurality of actuating plates are arranged circumferentially on the rotating shaft, and a drive gear is installed on the circumferential surface of the rotating shaft.

[0011] A rack plate is installed on the stamping frame to mesh with the drive gear.

[0012] The bottom frame is also equipped with a reciprocating frame that can move vertically, and the reciprocating frame is equipped with a linkage plate that cooperates with the actuating plate.

[0013] The reciprocating frame is connected to the reciprocating frame via a reciprocating block.

[0014] Preferably, the reciprocating frame is mounted on the bottom frame via a telescopic spring rod.

[0015] Preferably, the bottom frame is provided with four vertical rods arranged in a rectangular pattern, and the stamping frame is slidably connected to the vertical rods.

[0016] A lifting cylinder is installed at the bottom of the stamping frame. The bottom of the extension and retraction end of the lifting cylinder is connected to the stamping block via a rotating shaft and is driven by a motor for rotating the rotating shaft.

[0017] Preferably, the bottom of the stamping frame is also equipped with a limiting frame for laterally limiting the brick blank during demolding.

[0018] Preferably, a U-shaped frame is also installed at the bottom of the bottom frame, and a lifting cylinder is installed on the horizontal section of the U-shaped frame, with a lifting plate installed at the telescopic end of the lifting cylinder.

[0019] A second rotating shaft is mounted on the lifting plate via a bearing. A lifting block is mounted on the top of the second rotating shaft. The bottom frame has a through slot that mates with the lifting block. The bottom of the stamping base plate has a matching slot that engages with the lifting block.

[0020] The lifting plate is also equipped with a motor 2 for driving the rotating shaft 2 to rotate.

[0021] Preferably, a lifting rod is also installed on the lifting plate, a pushing block is installed on the top of the lifting rod, and a through groove that cooperates with the pushing block is provided through the bottom frame.

[0022] Preferably, a linkage frame is installed on the side of the stamping frame away from the forming frame, and a leveling frame is installed on the linkage frame. An inverted T-shaped leveling frame is provided at the bottom of the leveling frame. The vertical section of the leveling frame is slidably mounted on the leveling frame. Multiple connecting rods perpendicular to the leveling frame are evenly installed at the bottom of the leveling frame along its length, and multiple leveling rods are evenly arranged at the bottom of the connecting rods along their length.

[0023] Preferably, the leveling frame is further equipped with a linkage plate II, and an elastic telescopic rod is installed on the leveling frame via a fixed protrusion. The telescopic end of the elastic telescopic rod is installed on the vertical section of the leveling frame. A fixed frame is installed on the leveling frame, and a rotating shaft II is rotatably installed on the fixed frame via a bearing. Multiple actuating plates II for actuating the linkage plate II are evenly installed on the rotating shaft II along its circumference. A drive gear II is installed on the rotating shaft II, and a rack plate II that meshes with the drive gear II is installed on the bottom frame.

[0024] Secondly, an energy-saving rapid prototyping process for refractory bricks includes the following steps: quantitatively filling the raw material into the forming frame located at the starting station, and driving the forming frame to move at a fixed distance to the bottom of the stamping frame.

[0025] The stamping frame moves down, driving the stamping block to stamp the raw material, while the return frame moves up and down reciprocally.

[0026] After stamping is completed, the stamping base plate and the brick blank are lifted up, and the stamping base plate is driven to rotate, so that it is flexibly separated from the brick blank.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention utilizes a reciprocating motion of a forming frame driven by a first actuating plate, a first linkage plate, and a telescopic spring rod. Before stamping, the water on the surface of the forming frame rubs against the raw material to generate slurry. This slurry fills the tiny gaps on the surface of the brick blank, improving the smoothness of the blank surface and reducing defects. At the same time, the slurry forms a lubricant between the forming frame and the brick blank, reducing adhesion and preventing the forming frame from tearing the blank surface and causing damage during demolding. Furthermore, the small-amplitude reciprocating motion of the forming frame transforms the strong force during demolding into multiple weak forces, dispersing the contact pressure and preventing local stress concentration. This effectively prevents the sidewalls of the brick blank from tearing during removal, ensuring the quality of the blank forming.

[0028] 2. This invention utilizes the cooperation of a lifting cylinder, a rotating shaft one, a stamping block, a lifting cylinder, a rotating shaft two, and a stamping base plate. During demolding, motors one and two drive rotating shafts one and two to initially rotate back and forth with a small amplitude, causing the stamping block and stamping base plate to only rotate relative to the brick blank. Subsequently, the rotation amplitude is gradually increased, slowly breaking through the adhesion limit, so that the separation process of the stamping block and stamping base plate from the brick blank changes from hard tearing to flexible separation. This design avoids stress concentration and tearing on the surface of the brick blank caused by a one-time strong force, significantly improving the stability and reliability of the demolding process and ensuring the structural integrity of the brick blank.

[0029] 3. This invention utilizes the cooperation of a leveling frame, a leveling rod, a connecting rod, and a leveling rod to evenly distribute and level the raw material within the forming frame before stamping. When the stamping frame moves downward, it drives the leveling frame to move synchronously, and the leveling rod enters the forming frame. The rotating shaft two rotates by meshing with the rack plate two through the drive gear two, driving the actuating plate two to actuate the linkage plate two, causing the leveling frame to reciprocate along the width direction of the bottom frame, thereby driving the leveling rod to reciprocate and level the raw material. This process ensures that the raw material layer thickness is consistent and the surface is regular, providing a uniform distribution of raw material for subsequent stamping and forming. Combined with the demolding treatment after stamping, this process prevents tearing of the brick blank surface, improving the overall quality and production efficiency of refractory bricks.

[0042] The following is in conjunction with the appendix Figures 1 to 11 This application will be described in further detail.

[0043] This application discloses an energy-saving rapid prototyping equipment and process for refractory bricks. This solution significantly improves the surface quality of the brick blanks by implementing a uniform distribution technology for raw materials and effectively reducing the adhesion between the brick blank surface and the prototyping equipment.

[0044] Reference Figure 1 as well as Figure 2 An energy-saving refractory brick rapid prototyping equipment includes a bottom frame 1, on which multiple forming frames 2 are evenly slidably arranged along its length. A stamping mechanism 3 is also installed on the bottom frame 1. The stamping mechanism 3 consists of four vertical rods 31 arranged in a rectangular shape. A stamping frame 32 is installed on the vertical rods 31. A stamping block 33 is installed at the bottom of the stamping frame 32.

[0045] The adjacent forming frames 2 are symmetrically arranged with spacers 21 along the width direction of the bottom frame 1 to ensure that the adjacent forming frames 2 maintain a certain distance and avoid interference between the adjacent forming frames 2 during operation. The forming frame 2 has a vertical through structure. The inner side wall of the forming frame 2 is provided with a sliding U-shaped frame 22. The bottom of the forming frame 2 is also provided with a stamping base plate 23 that cooperates with the stamping block 33.

[0046] Specifically, the forming frame 2 is symmetrically provided with reciprocating blocks 24 along the width direction of the bottom frame 1, and the reciprocating blocks 24 are slidably provided on the forming frame 2. The bottom frame 1 is symmetrically provided with support frames 25 that cooperate with the reciprocating blocks 24. A rotating shaft 26 is rotatably installed between the support frames 25 through bearings. One end of the rotating shaft 26 is installed on the forming frame 22 along its circumference. Multiple actuating plates 27 are evenly provided on the rotating shaft 26 along its circumference. A drive gear 28 is also provided on the rotating shaft 26, and a rack plate 29 that meshes with the drive gear 28 is installed on the stamping frame 32.

[0047] Above the bottom frame 1, there is a reciprocating frame 20 with a U-shaped structure and an opening facing the corresponding forming frame 2. A telescopic spring rod 210 is installed on the bottom frame 1, and the reciprocating frame 20 is installed on the telescopic spring rod 210. On the side of the reciprocating frame 20 away from the corresponding forming frame 2, there is a linkage plate 211 that cooperates with the actuating plate 27.

[0048] A lifting cylinder 321 is also mounted on the bottom of the stamping frame 32 via a cylinder seat. A limiting frame 322 that cooperates with the stamping block 33 is also mounted on the bottom of the stamping frame 32. A rotating shaft 323 is rotatably mounted on the bottom of the extension end of the lifting cylinder 321 via a bearing. The stamping block 33 is mounted on the bottom of the rotating shaft 323. A motor 324 is mounted on the motor seat on the extension end of the lifting cylinder 321. The output shaft of the motor 324 is connected to the rotating shaft 323 via gear meshing.

[0049] In specific work, such as Figure 1 The arrow indicates the forward direction of the forming frame 2. At the starting position, a certain amount of raw material is poured into the forming frame 2. The forming frame 2 containing the raw material is moved by an external drive (cylinder, etc., not shown in the figure). After the forming frame 2 has moved a distance of one forming frame 2, a new forming frame 2 is placed at the starting position, and a spacer block 21 is placed between the two forming frames 2. The raw material is then poured into the corresponding forming frame 2 in a certain amount. The above actions are repeated, and the forming frame 2 containing the raw material can be moved forward by the cooperation of the existing external drive and the spacer block 21.

[0050] Since the forming frame 2 is a fixed-distance conveyor, when the forming frame 2 containing the raw material moves to the bottom of the stamping frame 32, the forming frame 2 is located at the bottom of the stamping block 33 by default. At this time, the corresponding reciprocating block 24 moves to the two horizontal sections of the reciprocating frame 20 on the corresponding side, and the lifting cylinder 321 is activated. The extension end of the lifting cylinder 321 drives the stamping block 33 to move out of the limit frame 322 through the rotating shaft 323, so that the stamping block 33 maintains a safe distance between the forming frame 2 and the limit frame during the downward stamping process, and avoids rigid collision between the limit frame 322 and the forming frame 2 during the downward process of the stamping head. In addition, the rotating shaft 323 will not rotate relative to the forming frame during this process.

[0051] It should be noted that before placing the raw material and stamping, water is sprayed onto the surfaces of the parts (such as the forming frame 22, the stamping base plate 23, and the stamping block 33) that come into contact with the raw material using existing water pumps and water pipes (neither of which are shown in the figure). This prevents the raw material from sticking to the forming frame 22 and its inner wall when it is placed. At the same time, after the brick blank is stamped, a water film is formed between the brick blank and the corresponding parts. This water film reduces the adhesion between the brick blank and the corresponding parts, making it easier to remove the brick blank from the forming frame 2. It also prevents the brick blank from breaking due to adhesion during demolding, thus ensuring the quality of the brick blank forming.

[0052] In actual operation, the lifting cylinder 321 is activated to drive the stamping block 33 downward through the existing drive (cylinder, etc., not shown in the figure) to stamp the raw material inside the forming frame 2, so that the raw material is compacted and forms a brick blank. That is, when the stamping frame 32 just begins to move downward, the stamping block 33 has not yet entered the forming frame 2. The stamping frame 32 drives the rack plate 29 to move synchronously. During the movement of the rack plate 29, it meshes with the drive gear 28 to drive the rotating shaft 26 to rotate. During the rotation of the rotating shaft 26, it drives the actuating plate 27 to rotate synchronously. When the actuating plate 27 contacts the corresponding linkage plate 211, the circumferential force on the actuating plate 27 will give the linkage plate 211 an upward component force. This component force can drive the reciprocating frame 20 to move upward through the linkage plate 211. During the upward movement of the reciprocating frame 20, the return frame 22 is driven to move upward synchronously through the reciprocating block 24. At this time, the telescopic spring rod 210 is stretched.

[0053] When the corresponding actuating plate 27 disengages from the linkage plate 211, the telescopic spring rod 210 drives the reciprocating block 24 to reset and move downward through the reciprocating frame 20, and the return frame 22 resets simultaneously. As the return frame 22 moves back and forth, the water on its surface rubs against the raw material to form mud. The mud formed can fill the tiny gaps on the surface of the brick blank during the subsequent stamping process, making the surface of the subsequently stamped brick blank smoother and reducing surface defects of the brick blank.

[0054] In addition, the slurry can act as a lubricant between the brick blank and the forming frame 22, further reducing the adhesion between the forming frame 22 and the brick blank when it moves back and forth, and avoiding the possibility that the forming frame 22 will tear the surface of the brick blank when it is removed later, which could lead to damage to the surface of the brick blank.

[0055] Thus, through the above steps, the small up-and-down reciprocating motion of the reciprocating frame 22 can transform the one-time strong force applied when the brick blank is removed in one go into multiple dispersed weak forces, gradually reducing the contact pressure between the reciprocating frame 22 and the brick blank, avoiding local stress concentration, and ensuring that the side wall of the brick blank will not tear when it is removed in the subsequent process.

[0056] A U-shaped frame 11 with an upward opening is provided on the side of the bottom frame 1 away from the stamping frame 32. The two vertical sections of the U-shaped frame 11 are installed on the bottom frame 1. A lifting cylinder 12 is installed on the horizontal section of the U-shaped frame 11. A lifting plate 13 is installed on the telescopic end of the lifting cylinder 12. A rotating shaft 14 that cooperates with the stamping block 33 is rotatably installed on the lifting plate 13 through a bearing. A motor 15 is installed at the bottom of the lifting plate 13 through a motor base. The output shaft of the motor 15 and the rotating shaft 14 are connected by gear meshing.

[0057] A lifting block 16 is installed on the top of the rotating shaft 14. A through slot 17 that mates with the lifting block 16 is provided on the bottom frame 1. A matching slot 18 that mates with the through slot 17 is provided on the stamping base plate 23. A lifting rod 19 is also installed on the lifting plate 13. A pushing block 10 is installed on the top of the lifting rod 19. The pushing block 10 mates with the stamping base plate 23 to push the brick blank out from inside the forming frame 2. A through slot that mates with the pushing block 10 is provided on the bottom frame 1.

[0058] In specific operations, after the sidewall of the brick blank is treated to prevent tearing, the lifting cylinder 12 is activated. During the movement of the extension end of the lifting cylinder 12, the rotating shaft 14 moves synchronously through the lifting plate 13. During the movement of the rotating shaft 14, the lifting block 16 moves synchronously. During the movement of the lifting block 16, it passes through the through groove 17 and is engaged inside the mating groove 18. At this time, the lifting block 16 synchronously drives the stamping base plate 23 to move upward.

[0059] In order to coordinate with the upward movement of the stamping base plate 23, the lifting cylinder 321 is activated at this time, and the moving speed of the extension end of the lifting cylinder 321 is consistent with that of the extension end of the lifting cylinder 12. Thus, during the movement of the extension end of the lifting cylinder 321, the stamping block 33 and the stamping base plate 23 are in a relatively stationary state relative to the brick blank, so as to avoid the stamping block 33, the stamping base plate 23 and the brick blank having different moving speeds, which would cause the stamping block 33 and the stamping base plate 23 to have a tearing effect on the brick.

[0060] At this time, the stamping base plate 23 drives the brick blank to move upward. When the top of the brick blank just moves to the top of the forming frame 2, the plane formed by the top of the brick blank and the bottom of the stamping block 33 is exactly level with the top of the forming frame 2. At this time, the motor 324 is started. It should be noted that the output shaft of the motor 324 is reciprocating. At the beginning, the rotation amplitude of the output shaft of the motor 324 is very small. That is, during the reciprocating rotation of the output shaft of the motor 324, the rotating shaft 323 is driven to reciprocate through gear transmission. Since the stamping block 33 and the brick blank are adhered to each other, the rotating shaft 323 initially drives the stamping block 33 to only have a relative rotation tendency. As time increases, the rotation amplitude of the rotating shaft 323 gradually increases. When the rotation amplitude of the rotating shaft 323 reaches a certain threshold, the balance between the bottom of the stamping block 33 and the brick blank is broken, and the stamping block 33 and the brick blank separate from each other.

[0061] At this time, the bottom of the stamping plate and the stamping block 33 continue to move upward synchronously, so that the brick blank moves into the inside of the limiting frame. When the bottom of the brick blank is level with the bottom of the limiting frame, the second motor 15 is started. It should be noted that the output shaft of the second motor 15 is reciprocating, and at the beginning, the rotation amplitude of the output shaft of the second motor 15 is very small. That is, during the reciprocating rotation of the output shaft of the second motor 15, the rotating shaft 14 is driven to reciprocate through gear transmission. Since the stamping base plate 23 and the brick blank are adhered to each other, the rotating shaft 14 initially drives the stamping base plate 23 to only have a relative rotation tendency through the lifting block 16. As time increases, the rotation amplitude of the rotating shaft 14 gradually increases. When the rotation amplitude of the rotating shaft 14 reaches a certain threshold, the balance between the top of the stamping base plate 23 and the brick blank is broken, and then the stamping base plate 23 and the brick blank separate from each other.

[0062] Furthermore, the rotating shaft 323 and the rotating shaft 14 are initially driven by small-amplitude reciprocating rotation, so that the stamping block 33 only generates a rotational tendency relative to the brick blank, rather than directly and forcibly twisting. This design can first gradually loosen the local adhesion points between the stamping block 33, the stamping base plate 23 and the brick blank, avoiding damage to the surface structure by a one-time strong force. Then, by gradually increasing the rotation amplitude, the torsional force slowly breaks through the adhesion limit, so that the separation process changes from hard tearing to flexible separation. Compared with direct forced separation, it can greatly reduce the possibility of the brick blank surface tearing due to stress concentration, and improve the stability and reliability of the subsequent demolding of the brick blank.

[0063] Subsequently, the bottom of the stamping moves down, causing the brick blank to reset. At this time, the stamping frame 32 is activated to limit the brick blank during the reset process through the limiting frame until the limiting frame is in contact with the forming frame 2. The stamping frame 32 no longer moves. At this time, the stamping bottom plate 23 continues to drive the brick blank to move down until the brick blank is reset.

[0064] During the above process, the limiting frame can limit the brick blank, preventing the brick blank from rotating synchronously when the stamping base plate 23 rotates. At the same time, the limiting frame can also provide lateral support and limit the side wall of the brick blank, preventing the brick blank from collapsing in all directions due to gravity and high moisture content.

[0065] The present invention can also optimize the raw material arrangement process to improve the surface quality of the brick blank. Specifically, a linkage frame 4 is installed on the side of the stamping frame 32 away from the forming frame 2. A leveling frame 41 is installed on the linkage frame 4. A leveling frame 42 with an inverted T-shaped structure is provided at the bottom of the leveling frame 41. The vertical section of the leveling frame 42 is slidably arranged on the leveling frame 41. Multiple connecting rods 43 perpendicular to the leveling frame 42 are evenly installed at the bottom of the leveling frame 42 along its length direction. Multiple leveling rods 44 are evenly arranged at the bottom of the connecting rods 43 along their length direction.

[0066] A linkage plate 45 is installed on the leveling frame 42. An elastic telescopic rod 46 is installed on the leveling frame 41 through a fixed protrusion. The telescopic end of the elastic telescopic rod 46 is installed on the vertical section of the leveling frame 42. A fixed frame 47 is installed on the leveling frame 41. A rotating shaft 48 is rotatably installed on the fixed frame 47 through a bearing. Multiple actuating plates 49 for actuating the linkage plate 45 are evenly installed on the rotating shaft 48 along its circumference. A drive gear 40 is installed on the rotating shaft 48. A rack plate 410 that meshes with the drive gear 40 is installed on the bottom frame 1.

[0067] During the actual operation, the stamping frame 32 moves down and the leveling frame 41 moves down synchronously through the linkage frame 4. The leveling frame 42 moves down synchronously during the movement of the leveling frame 41. At this time, the leveling frame 42 drives the leveling rod 44 to enter the forming frame 2 to be stamped through the connecting frame. At this time, the leveling frame 41 drives the rotating shaft 48 to move down synchronously through the fixed frame 47. During the movement of the rotating shaft 48, it rotates by meshing with the rack plate 410 through the drive gear 40.

[0068] During the rotation of the rotating shaft 48, the actuating plate 49 rotates synchronously. When the actuating plate 49 contacts the corresponding linkage plate 45, the circumferential force on the actuating plate 49 will give the linkage plate 45 a component force toward the leveling frame 41. This component force can drive the vertical section of the leveling frame 42 to move away from the rack plate 410 through the linkage plate 45. At this time, the balance frame drives the leveling rod 44 to move synchronously through the connecting rod 43, and the elastic telescopic rod 46 is compressed.

[0069] When the corresponding actuating plate 49 disengages from the linkage plate 45, the elastic telescopic rod 46 drives the leveling frame 42 to reset. Repeating the above actions will drive the leveling rod 44 to move back and forth. In the process, the leveling rod 44 moves back and forth synchronously along the width direction of the bottom frame 1. Thus, the leveling rod 44 can evenly distribute and level the raw material inside the forming frame 2, ensuring that the thickness of the raw material layer is consistent and the surface is regular.

[0070] By combining the uniform distribution of raw materials before stamping with the demolding treatment after stamping, the surface of the brick blank can be treated to prevent tearing during subsequent demolding. After the above steps are completed, all parts are reset. At this time, the demolded forming frame 2 continues to move to the next station. Repeating the above steps can produce brick blanks in batches. During the above steps, the lifting plate 13 moves upward and cooperates with the lifting rod 19 to drive the pushing block 10 to push the formed brick blank out of the treatment frame after the tear-proof treatment. The obtained brick blank is dried to form refractory bricks.

[0071] Finally, the present invention also provides an energy-saving rapid prototyping process for refractory bricks, including the following steps: S1: At the starting position of the bottom frame 1, a quantitative amount of raw material is poured into the forming frame 2; then, the forming frame 2 is moved one station along the length direction of the bottom frame 1 by an external drive (such as a cylinder), and spacers 21 are placed between adjacent forming frames 2 to maintain distance and avoid interference. This process is repeated to achieve continuous fixed-distance conveying of multiple forming frames 2. When the forming frame 2 moves to the bottom of the stamping frame 32, its position is exactly aligned with the stamping block 33. Before filling and stamping, the equipment sprays water onto the forming frame 22, the stamping base plate 23 and the stamping block 33 through a water pump to form a water film.

[0072] S2: After the raw material is in place, the lifting cylinder 321 is activated to drive the stamping block 33 to move down, and the raw material in the forming frame 2 is stamped and compacted to form a brick blank. When the stamping frame 32 moves down, the meshing of the rack plate 29 and the drive gear 28 drives the rotating shaft 26 to rotate, which causes the actuating plate 27 to push the linkage plate 211. Then, through the reciprocating frame 20 and the reciprocating block 24, the return frame 22 moves up and down slightly. This action causes the water on the surface of the return frame 22 to rub against the raw material to generate mud, which fills the gaps on the surface of the brick blank and improves the surface smoothness. At the same time, the mud acts as a lubricant.

[0073] S3: After stamping is completed, the lifting cylinder 12 is started, which drives the rotating shaft 14 and the lifting block 16 to move upward through the lifting plate 13. The lifting block 16 is inserted into the mating groove 18 of the stamping base plate 23 through the through groove 17, pushing the stamping base plate 23 and the brick blank to rise synchronously. In order to maintain relative stillness, the lifting cylinder 321 and the lifting cylinder 12 have the same speed to prevent tearing. When the top of the brick blank is flush with the forming frame 2, the motor 324 drives the rotating shaft 323 to rotate back and forth in a small amplitude, gradually breaking the adhesion balance between the stamping block 33 and the brick blank, and realizing flexible separation. Then the motor 15 operates in the same way to separate the stamping base plate 23 from the blank.

[0074] S4: After demolding, the stamping base plate 23 drives the brick blank to move down and reset. The limiting frame 322 provides lateral support to prevent the brick blank from collapsing. At the same time, when the stamping frame 32 moves down, the linkage frame 4 drives the leveling frame 41 and the leveling rod 44 into the forming frame 2. The rotating shaft 48 rotates due to gear meshing, driving the actuating plate 49 to actuate the linkage plate 45, so that the leveling rod 44 moves back and forth along the width of the frame to evenly level the raw material. Finally, the lifting rod 19 pushes the brick blank out of the forming frame 2. After drying, it becomes a refractory brick. After all parts are reset, the forming frame 2 moves to the next station and repeats the above steps to achieve mass production.

[0075] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0076] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
