Description

Technical Field

[0001] The present application belongs to the technical field of compression molding, and specifically relates to a brick pressing molding device and a brick pressing method for high-strength, wear-resistant, and high-alumina refractory bricks. Background Art

[0002] Refractory bricks, also known as fire bricks, are refractory materials made by burning refractory clay or other refractory raw materials. The actual processing of refractory bricks requires adding refractory powder into the forming groove of the punch seat, and then the punch moves downward quickly to hit the forming groove, thereby compacting the refractory powder in the forming groove to form refractory bricks. Generally, refractory bricks have standard shapes and can also be temporarily processed according to needs. The production of shaped refractory bricks generally goes through the following processes: crushing - mixing - molding - firing - packaging - delivery.

[0003] Chinese invention patent CN110524680B discloses a refractory brick forming device, including a workbench, the four corners of the bottom surface of the workbench are fixedly connected to support legs, the top surface of the workbench is fixedly connected to a bearing frame, and the center of the top surface of the bearing frame is fixedly connected to a hydraulic oil tank; the refractory brick pressing forming device has low pressing efficiency, poor pressing effect, and the pressing quality cannot meet the requirements.

[0004] Chinese invention patent CN116551820B relates to the field of refractory brick forming technology, specifically a refractory brick forming mold, including a machine table, a guide column, a hydraulic pump station, a fixing structure, a forming structure, a cleaning structure, a driving structure, a mounting structure, a feeding structure and a mounting frame; the pressing and forming device of the refractory brick requires manual operation, has high operating difficulty and low operating intensity, and cannot meet the needs of mass production and processing.

[0005] In the prior art, raw materials need to be added into the pressing cavity manually, so the amount of raw materials in the pressing cavity cannot be accurately guaranteed, and the amount of raw materials cannot be subsequently adjusted when the raw materials are actually pressed into shape. The size or density of the refractory bricks after pressing and forming does not meet the requirements, and too much or too little raw materials will affect the quality of the pressed refractory bricks.

[0006] At the same time, since the fluffiness of the raw materials is different in different environments, the density of the refractory bricks is different after the raw materials are directly poured into the pressing cavity for pressing and molding, and irregular accumulation is prone to occur on the top of the raw materials, which makes the top of the raw materials unable to be in a horizontal state and will affect the subsequent pressing efficiency and pressing quality of the raw materials.

[0007] When used for a long time, some raw materials are easily attached to the inner wall of the pressing cavity, which will not only reduce the smoothness of the outer surface of the refractory bricks, but also affect the subsequent processing of the refractory bricks.

[0008] After the processing of the refractory bricks is completed, the refractory bricks and the lower pressure plate need to be demoulded manually. This demoulding method is inefficient and easily causes the refractory bricks to stick to the top of the lower pressure plate and cause damage to the outer surface of the refractory bricks, thereby reducing the smoothness and integrity of the outer surface structure of the refractory bricks.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] First embodiment

[0044] like Figure 1-3 As shown, a high-strength wear-resistant high-alumina refractory brick pressing and forming device includes a base 1, a controller is provided on one side of the base 1, and the controller electrically controls various electrical components. Two clamps 2 are symmetrically provided on the top of the base 1, and a lower mold 4 is provided between the two clamps 2. With the help of the clamping effect of the clamp 2 on the lower mold 4, the stability and installation accuracy of the lower mold 4 are further improved. A pressing cavity 5 is opened on the top of the lower mold 4, and a lower pressing plate 14 is slidably connected to the inside of the pressing cavity 5. The lower pressing plate 14 moves up and down inside the pressing cavity 5 to perform the pressing and forming process of the refractory bricks.

[0045] The clamps 2 are provided with threaded grooves on both sides facing each other, and the inside of the threaded grooves are threadedly connected with fixing screws 3. The fixing screws 3 adjust the gap between the two clamps 2. The inner wall of the clamps 2 matches the outer surface of the lower mold 4, thereby ensuring that the two clamps 2 are installed and fixed to the lower mold 4. The inner wall of the pressing cavity 5 is sealed and slidably connected to the outer surface of the lower pressing plate 14. When the lower pressing plate 14 moves up and down inside the pressing cavity 5, the raw material on the top will not fall off. Four sliding grooves are symmetrically arranged on the top of the base 1, and two sliding blocks are symmetrically arranged on the bottom of the two clamps 2. The sliding grooves match the sliding blocks, which further improves the stability and limiting property of the sliding of the clamps 2 on the top of the base 1.

[0046] There are columns 6 on both sides of the base 1, and a fixed platform 7 is provided on the top of the column 6. A hydraulic cylinder 8 is provided at the bottom of the fixed platform 7. The fixing platform 7 is used to further improve the installation stability of the hydraulic cylinder 8. An output rod 9 is provided at the bottom output end of the hydraulic cylinder 8, and an upper mold 12 is provided at the bottom of the output rod 9. When the controller controls the hydraulic cylinder 8 to start extending, the bottom output end of the hydraulic cylinder drives the output rod 9 to move downward, and the output rod 9 drives the upper mold 12 at the bottom to move downward. A pressing block 13 is provided at the bottom of the upper mold 12, and the outer surface of the pressing block 13 matches the interior of the pressing cavity 5. The pressing block 13 cooperates with the lower pressing plate 14 to press and form the raw material inside the pressing cavity 5.

[0047] Side rods 10 are provided on both sides of the output rod 9, and a limiting groove is provided on the other side of the side rod 10. A limiting rod 11 is provided on the end surface facing the column 6. The limiting rod 11 is sealed and slidably connected with the limiting groove, which further improves the stability and limiting property of the up and down movement of the output rod 9, and avoids the displacement of the bottom upper mold 12 and the pressing block 13 when moving, which affects the pressing and molding effect of the raw material.

[0048] The inner bottom of the pressing chamber 5 is evenly provided with a plurality of bottom grooves 15, the inner bottom of the bottom groove 15 is provided with a connecting spring 16, and the top of the connecting spring 16 is provided with a bottom rod 17. The setting of the connecting spring 16 further improves the elastic reset performance of the bottom rod 17, and the outer surface of the bottom rod 17 is sealed and slidably connected with the inner wall of the bottom groove 15, which effectively prevents foreign matter from entering the bottom groove 15 and affecting the movement of the bottom rod 17. The top of the bottom rod 17 is fixedly connected to the bottom of the lower pressing plate 14. When the lower pressing plate 14 moves up and down inside the pressing chamber 5, the lower pressing plate 14 drives the bottom rod 17 to move up and down, and the bottom rod 17 squeezes the connecting spring 16 inside the bottom groove 15 to move up and down, thereby elastically supporting the movement of the lower pressing plate 14, and cooperating with the pressing block 13 to press and form the raw material inside the pressing chamber 5.

[0049] An ejector cylinder 18 is provided at the inner center of the lower mold 4, and an ejector rod 19 is provided at the top of the ejector cylinder 18. The top of the ejector rod 19 matches the bottom axis of the lower pressure plate 14. When the pressing of the refractory bricks is completed, the controller first controls the hydraulic cylinder 8 to shorten in the reverse direction and move upward and out of the pressing chamber 5 through the bottom output rod 9, the upper mold 12 and the pressing block 13. Then the controller controls the ejector cylinder 18 to start extending and drive the top ejector rod 19 to move upward to the maximum distance. The ejector rod 19 drives the lower pressure plate 14 to move upward, and the lower pressure plate 14 drives the top refractory bricks to move upward and out of the pressing chamber 5, takes out the refractory bricks inside the pressing chamber 5 and completes the processing procedure. An external connection hole is connected to one side of the inner bottom of the pressing chamber 5, and the other end of the external connection hole is connected to the outside world. The setting of the external connection hole improves the stability of the lower pressure plate 14 moving up and down in the pressing chamber 5 and the gas flowability, and avoids the negative pressure effect to reduce the stability of the movement of the lower pressure plate 14.

[0050] When in use, after the device is installed, first pour the raw material into the pressing chamber 5, the controller controls the hydraulic cylinder 8 to start extending and drive the output rod 9 at the bottom to move downward, the output rod 9 drives the pressing block 13 to move downward to the inside of the pressing chamber 5 through the upper mold 12, at this time the pressing block 13 applies pressure to the top of the raw material and drives the raw material to move downward, when the raw material is squeezed, it drives the bottom lower pressure plate 14 to move downward, the lower pressure plate 14 drives multiple groups of bottom rods 17 to squeeze the connecting spring 16 in the bottom groove 15 to move downward, and then uses the elastic force of the connecting spring 16 to apply an upward force to the lower pressure plate 14 through the bottom rod 17, then the lower pressure plate 14 and the pressing block 13 cooperate and press the raw material in the middle into refractory bricks.

[0051] Since the raw material cannot be directly pressed into refractory bricks in one time, the controller controls the hydraulic cylinder 8 to start in reverse and shorten it, and drives the pressing block 13 to move upward and return to its original position through the upper mold 12. At this time, the pressure value on the top of the lower pressing plate 14 is reduced, and under the elastic force of the connecting spring 16, the lower pressing plate 14 is driven to move upward and return to its original position through the bottom rod 17. The above process is repeated continuously, and the raw material is pressed into refractory bricks with the help of multiple cooperation between the pressing block 13 and the lower pressing plate 14.

[0052] When the pressing process is completed, the controller controls the hydraulic cylinder 8 to start shortening in reverse and drive the pressing block 13 to move upward and return to its original position through the upper mold 12. At the same time, the controller controls the ejection cylinder 18 to start extending and drive the top ejector rod 19 to move upward to the maximum distance. At this time, the ejector rod 19 and the bottom of the lower pressure plate 14 squeeze and contact each other and drive the lower pressure plate 14 to move upward along the pressing cavity 5 to the maximum distance. The lower pressure plate 14 drives the top refractory bricks to move upward to the maximum distance. At this time, you only need to take out the refractory bricks and repeat the above process continuously to complete the pressing and forming of refractory bricks in batches.

[0053] The device has high pressing efficiency and good pressing effect, which meets the actual processing needs and effectively improves the pressing quality of refractory bricks. At the same time, the various structures cooperate with each other, the operation is simple, stable and efficient, which further reduces the labor intensity of processing. It has strong limiting and supporting properties, precise and stable regulation, and strong adaptability to the pressing of refractory bricks, realizing energy conservation, emission reduction, and green and environmentally friendly processing needs.

[0054] Second embodiment

[0055] like Figure 4-8 As shown, since the prior art relies on manual feeding into the pressing chamber 5, the amount of raw materials in the pressing chamber 5 cannot be guaranteed to be accurate, and the subsequent amount of raw materials in the pressing chamber 5 cannot be adjusted, so the size and density of the refractory bricks after pressing and forming often do not meet the requirements, thereby reducing the processing quality of the refractory bricks; and since the raw materials have different fluffiness under different environments, after the raw materials are directly poured into the pressing chamber 5, the raw materials will accumulate on the top of the lower pressing plate 14, and the top of the raw materials needs to be manually smoothed, which will not only reduce the processing efficiency, but also the flatness of the top of the raw materials cannot be guaranteed; and when used for a long time, the inner wall of the pressing chamber 5 is prone to adhere to the raw materials, which will not only reduce the smoothness of the outer surface of the refractory bricks, but also affect the subsequent processing of the refractory bricks; when the processing of the refractory bricks is completed, the refractory bricks and the lower pressing plate 14 need to be demolded manually, and this demolding method is inefficient and easily causes scratches on the outer surface of the refractory bricks, thereby reducing the smoothness and integrity of the outer surface of the refractory bricks.

[0056] In order to solve the above problems, the high-strength wear-resistant high-alumina refractory brick pressing and forming device also includes: a distance sensor 36 is provided at the inner bottom of the pressing cavity 5, and the distance sensor 36 is used to detect the distance value between the inner bottom of the pressing cavity 5 and the bottom of the lower pressing plate 14.

[0057] A side groove 20 is provided inside the lower mold 4, and a material port 35 is provided on one side of the side groove 20 close to the pressing chamber 5, and the other end of the material port 35 is connected with the pressing chamber 5. Therefore, excess raw material in the pressing chamber 5 can directly enter the side groove 20 along the material port 35 for storage, and when the amount of raw material in the pressing chamber 5 is insufficient, the raw material in the side groove 20 can also be discharged into the pressing chamber 5 along the material port 35 in the opposite direction for replenishment. An arc surface 24 is provided at the bottom of the material port 35, and the bottom of the arc surface 24 is connected with the top of the side groove 20. The setting of the arc surface 24 further improves the smoothness and stability of the flow of raw materials in the pressing chamber 5 and the side groove 20, thereby improving the efficiency and effect of replenishing the raw materials in the pressing chamber 5.

[0058] An electromagnetic block 21 is provided at the inner bottom of the side groove 20, and a return spring 22 is provided at the top of the electromagnetic block 21. A magnetic push block 23 is provided at the top of the return spring 22. The magnetic properties of the end faces facing each other of the electromagnetic block 21 and the magnetic push block 23 are the same. When the controller controls the electromagnetic block 21 to be energized, the magnetic push block 23 is driven to stretch the return spring 22 and move upward by means of the magnetic repulsion force between the electromagnetic block 21 and the magnetic push block 23. The peripheral side surface of the magnetic push block 23 is sealed and slidably connected with the inner wall of the side groove 20. This arrangement effectively improves the sealing performance of the movement of the magnetic push block 23. The raw material located on the top of the magnetic push block 23 will not fall into the inside of the side groove 20 and hinder the movement of the magnetic push block 23. A weight sensor is provided on the top of the magnetic push block 23. The weight sensor is used to detect the weight value of the raw material on the top of the magnetic push block 23, thereby realizing precise adjustment of the amount of raw material inside the pressing chamber 5.

[0059] The inner wall of the side groove 20 is evenly provided with multiple groups of elastic protrusions 25, and the elastic protrusions 25 match the side walls of the magnetic push blocks 23. When the magnetic push blocks 23 move up and down inside the side groove 20, the magnetic push blocks 23 and the elastic protrusions 25 squeeze and collide with each other and drive the lower mold 4 to vibrate synchronously. With the help of this vibration, the vibration compaction process of the raw materials inside the pressing cavity 5 can be effectively improved, and the up and down movement of the lower pressing plate 14 can also be used to realize the vibration cleaning function of the raw materials adhered to the inner wall of the pressing cavity 5, thereby improving the cleanliness of the inside of the pressing cavity 5 and the tightness of the raw materials on the top of the lower pressing plate 14.

[0060] A plurality of vent holes 26 are evenly arranged inside the lower pressure plate 14, and a piston ring 29 is slidably connected inside the vent hole 26. A plug rod 31 is provided on the top of the piston ring 29. When the piston ring 29 moves up and down inside the vent hole 26, the piston ring 29 drives the plug rod 31 to move synchronously. A matching hole 30 is provided at the center axis of the piston ring 29, and an exhaust hole 32 is provided at the center axis of the plug rod 31. The matching hole 30 and the exhaust hole 32 are connected. The gas inside the vent hole 26 enters the exhaust hole 32 along the matching hole 30. A pressure valve 33 is provided at the top of the inner wall of the exhaust hole 32. The pressure valve 33 is provided with a preset pressure value. When the air pressure value inside the exhaust hole 32 does not reach the preset pressure value set by the pressure valve 33, the pressure valve 33 is closed, and when the air pressure value inside the exhaust hole 32 reaches the preset pressure value set by the pressure valve 33, the pressure valve 33 is opened, and the gas inside the exhaust hole 32 is discharged along the pressure valve 33.

[0061] A retaining ring 27 is provided at the top of the inner wall of the vent hole 26. The retaining ring 27 blocks the piston ring 29, which effectively prevents the insertion rod 31 from sliding out directly along the vent hole 26. The inner wall of the retaining ring 27 is sealed and slidably connected with the outer surface of the insertion rod 31. The top of the lower pressure plate 14, the retaining ring 27, the insertion rod 31 and the pressure valve 33 are all on the same horizontal plane. Therefore, in the initial state, the top of the lower pressure plate 14 is a smooth plane, thereby ensuring that the lower pressure plate 14 and the pressing block 13 cooperate and press-form refractory bricks with a smooth outer surface inside the pressing chamber 5.

[0062] A buffer spring 28 is provided at the bottom of the retaining ring 27, and the bottom of the buffer spring 28 is fixedly connected to the top of the piston ring 29. The buffer spring 28 is located on the outer surface of the insertion rod 31. The setting of the buffer spring 28 further improves the elastic reset performance of the piston ring 29. A blocking block 37 is provided at the bottom of the inner wall of the vent hole 26, and the top of the blocking block 37 matches the bottom of the piston ring 29. The setting of the blocking block 37 prevents the piston ring 29 from moving downward and disengaging from the vent hole 26.

[0063] The bottom of the vent 26 is connected with a connecting hose 34, the other end of the connecting hose 34 passes through the lower mold 4 and is connected to the side groove 20, the other end of the connecting hose 34 is located below the elastic protrusion 25, and the other end of the connecting hose 34 extends out of the inner wall of the side groove 20 and is greater than the height of the elastic protrusion 25. The connection mainly plays a role in gas connection. When the magnetic push block 23 moves downward inside the side groove 20, the magnetic push block 23 squeezes the gas at the bottom of the side groove 20, and the air pressure at the bottom of the side groove 20 increases, and the gas enters the vent 26 along the connecting hose 34. At the same time, when the magnetic push block 23 moves upward along the side groove 20, the air pressure at the bottom of the side groove 20 decreases, then the gas inside the vent 26 is extracted under the action of negative pressure and reversely enters the side groove 20, thereby effectively improving the gas flowability and the vibration of the raw materials and the demolding effect of refractory bricks.

[0064] When in use, first install each device as described in the first embodiment, and initially the controller controls the electromagnetic block 21 to be energized and magnetic, then the magnetic push block 23 is driven by the magnetic repulsion force of the electromagnetic block 21 to stretch the reset spring 22 to the initial position, and the lower pressure plate 14 is in the initial position under the elastic force of the connecting spring 16, and the distance between the top of the lower pressure plate 14 and the bottom of the material port 35 is the height value of the raw material that needs to be adjusted. The height value is the amount of raw material that needs to be added when the raw material is in the best state, which needs to be obtained through multiple tests and will not be elaborated here.

[0065] After that, the operator first pours the raw materials into the pressing chamber 5. Since the operator cannot accurately control the amount of raw materials added, and the fluffiness of the raw materials themselves is different under different environments, when the raw materials enter the pressing chamber 5, the raw materials at the end of the material port 35 directly enter the side groove 20 along the material port 35 and fall on the top of the magnetic push block 23. The weight difference detected by the weight sensor on the top of the magnetic push block 23 is the amount of excess raw materials in the pressing chamber 5 that enter the side groove 20.

[0066] At the same time, since the connecting spring 16 has a certain elastic force, the lower pressing plate 14 is still in the initial position and will not change when the raw materials are piled on the top of the lower pressing plate 14. At this time, the fluffiness of the raw materials on the top of the lower pressing plate 14 and the horizontality of the top meet the requirements, the controller controls the current of the electromagnetic block 21 to decrease, and the magnetic repulsion force exerted by the electromagnetic block 21 on the magnetic push block 23 is reduced. Under the elastic force of the reset spring 22, the magnetic push block 23 is driven to move downward, and the magnetic push block 23 squeezes the gas inside the side groove 20 along the connecting hose 34 into the vent 26. The air pressure inside the vent 26 increases and reaches the pressure valve 33 end along the matching hole 30 and the exhaust hole 32. At this time, with the help of the air pressure, the piston ring 29 is driven to squeeze the buffer spring 28 along the vent 26 and move upward, and the piston ring 29 drives the insertion rod 31 to move upward. The insertion rod 31 extends out along the top of the lower pressing plate 14 and continuously vibrates the raw materials on the top of the lower pressing plate 14, thereby improving the compactness of the raw materials and ensuring that the raw materials can be more densely stacked on the top of the lower pressing plate 14.

[0067] When the magnetic push block 23 moves downward, the magnetic push block 23 and the elastic protrusion 25 squeeze and collide with each other, and the elastic protrusion 25 synchronously drives the lower mold 4 to vibrate. Then, the material on the top of the lower pressure plate 14 effectively improves its own tightness and the horizontality of the top under the vibration of the insertion rod 31 and the vibration of the lower mold 4. When the current of the electromagnetic block 21 decreases to the set minimum preset value, the controller controls the current of the electromagnetic block 21 to increase to the set preset value again. Then, with the help of the magnetic repulsion force of the electromagnetic block 21 on the magnetic push block 23, the magnetic push block 23 is driven to stretch the reset spring 22 to move upward and return to its original position, and the corresponding magnetic push block 23 continues to contact the elastic protrusion 25 The collision drives the lower mold 4 to vibrate, and at the same time, the space at the bottom of the side groove 20 increases and the pressure decreases. Then, under the action of the negative pressure of the side groove 20, the gas inside the vent 26 is extracted and moves in the opposite direction along the connecting hose 34 to return to its original position. The piston ring 29 drives the insertion rod 31 to move downward and return to its original position under the action of the air pressure and the elastic force of the buffer spring 28. The insertion rod 31 is re-inserted into the vent 26 along the top of the lower pressure plate 14 to block the raw material, thereby completing the vibration process of the raw material. The above process is repeated continuously to further improve the plug-in vibration and vibration tightness of the raw material on the top of the lower pressure plate 14, ensure that the raw material on the top of the lower pressure plate 14 is placed evenly and tightly, thereby improving the subsequent effect of pressing the raw material into bricks.

[0068] After completing the vibration of the raw material on the top of the lower pressure plate 14, the controller controls the power-on current of the electromagnetic block 21 to return to the initial value. At the same time, the controller controls the hydraulic cylinder 8 to start extending and drive the output rod 9 at the bottom to move upward. The output rod 9 drives the pressing block 13 to move downward through the upper mold 12 and reaches the inside of the pressing cavity 5. At this time, the pressing block 13 squeezes the raw material and continues to move downward. The raw material drives the lower pressure plate 14 to move downward, and the distance value detected by the distance sensor 36 decreases. When the pressing block 13 moves downward to the set position and no longer moves downward, the raw material drives the lower pressure plate 14 to move downward to a suitable position and no longer moves downward.

[0069] At this time, if the amount of raw materials between the lower pressing plate 14 and the pressing block 13 meets the requirements, the raw materials drive the lower pressing plate 14 to be pressed down to an appropriate height, and the distance value detected by the distance sensor 36 reaches the preset distance value. Therefore, there is no need to add new raw materials between the lower pressing plate 14 and the pressing block 13. However, if the amount of raw materials itself does not meet the requirements when the raw materials are squeezed, the distance that the raw materials drive the lower pressing plate 14 to move downward is reduced, and the distance value detected by the distance sensor 36 is greater than the preset distance value. At this time, it means that the amount of raw materials between the lower pressing plate 14 and the pressing block 13 is small, that is, in the previous sequence, due to the fluffiness of the raw materials themselves, the amount of raw materials is reduced after the raw materials are vibrated, so the raw materials between the lower pressing plate 14 need to be supplemented.

[0070] At this time, the controller controls the hydraulic cylinder 8 to shorten in the reverse direction and drive the output rod 9 to move upward. The output rod 9 drives the pressing block 13 to move upward and return to its original position through the upper mold 12. The pressing block 13 reduces the extrusion force of the raw material on the top of the lower pressing plate 14. Then, under the elastic force of the connecting spring 16, the bottom rod 17 is driven to move upward and return to its original position. The bottom rod 17 drives the lower pressing plate 14 to move upward and return to its original position. At this time, since the raw material on the top of the lower pressing plate 14 is over-extruded, the height value of the raw material on the top of the lower pressing plate 14 is reduced and is less than the bottom height of the material port 35. At this time, the controller controls the electromagnetic block 21 The current of the power-carrying current increases and the magnetic repulsion force on the magnetic push block 23 increases. The magnetic push block 23 stretches the reset spring 22 to move upward, and the magnetic push block 23 drives the top raw material to move upward. When the raw material reaches the end of the material port 35, the raw material flows into the pressing cavity 5 along the material port 35 in the opposite direction and replenishes the raw material on the top of the lower pressing plate 14. The weight value detected by the weight sensor decreases. When the weight difference detected by the weight sensor meets the requirements, the weight difference is related to the distance value detected by the distance sensor 36, thereby completing the laying process of the raw material on the top of the lower pressing plate 14.

[0071] After the material is laid, the controller controls the hydraulic cylinder 8 to continue to start extending and drive the output rod 9 to move downward. The output rod 9 drives the pressure block 13 to move downward through the upper mold 12 to repeat the above process. At this time, since the raw material needs to be further pressed, the controller controls the hydraulic rod 8 to drive the output rod 9 to move downward to increase the distance, and the corresponding pressure value applied to the raw material by the pressure block 13 increases. The pressure block 13 drives the lower pressure plate 14 to move downward through the raw material. The distance sensor 36 is used to detect whether the distance value after the lower pressure plate 14 continues to stop moving downward in this case meets the set distance value. The above process is repeated continuously to realize the feeding process of the raw material on the top of the lower pressure plate 14, thereby ensuring that the amount of raw material between the lower pressure plate 14 and the pressure block 13 meets the requirements, and further ensuring that the size and density of the pressed refractory bricks between the lower pressure plate 14 and the pressure block 13 meet the requirements.

[0072] Afterwards, the controller controls the hydraulic cylinder 8 to move in the opposite direction to return to its original position, and the output rod 9 drives the pressing block 13 to move upward to return to its original position through the upper mold 12. At this time, the refractory bricks need to be demolded and unloaded, so the controller controls the ejection cylinder 18 to start and drive the ejection rod 19 to move upward to the maximum distance, and the ejection rod 19 and the bottom of the lower pressure plate 14 are squeezed and contacted with each other and move upward to the maximum distance, and the lower pressure plate 14 drives the refractory bricks to move upward and out of the pressing cavity 5. At this time, since the bottom of the refractory bricks are squeezed and contacted with the top of the lower pressure plate 14 for a long time, the bottom of the refractory bricks and the bottom of the lower pressure plate 14 will adhere to each other, which will easily reduce the subsequent demolding efficiency and demolding effect.

[0073] At this time, the controller electromagnetic block 21 is powered off, and the magnetic repulsion force of the electromagnetic block 21 on the magnetic push block 23 disappears. Then, under the elastic force of the reset spring 22, the magnetic push block 23 is driven to move downward to the minimum distance. When the magnetic push block 23 moves downward, it first squeezes and collides with the multiple groups of elastic protrusions 25. Then, the elastic protrusions 25 drive the lower mold 4 and the lower pressure plate 14 to vibrate, and the magnetic push block 23 squeezes the internal gas of the side groove 20 along the connecting hose 34 into the vent hole 26, and drives the piston ring 29 upward with the help of air pressure, and the piston ring 29 drives the insertion rod 31 upward When the amount of gas in the exhaust hole 32 increases continuously and is greater than the preset value of the air pressure set by the pressure valve 33, the pressure valve 33 opens, and the gas in the exhaust hole 32 is discharged upward along the pressure valve 33. The force exerted by the air pressure on the bottom of the refractory brick makes the refractory brick and the top of the insert rod 31 demould, thereby achieving the demoulding efficiency and demoulding effect of the refractory brick and the lower pressure plate 14 and the insert rod 31.

[0074] After that, the operator takes off the refractory bricks, thereby completing the processing of the refractory bricks. The controller controls the ejection cylinder 18 to start in the reverse direction, shorten it, and drive the ejection rod 19 to move downward. Then, the connecting spring 16 drives the bottom rod 17 to move downward and return to its original position. The bottom rod 17 drives the lower pressure plate 14 to move downward and return to its original position. At the same time, the controller controls the current of the electromagnetic block 21 to increase and reach the set initial value. At this time, the magnetic push block 23 stretches the reset spring 22 to move upward and return to its original position. At this time, the magnetic push block 23 and the multiple groups of elastic protrusions 25 contact and collide with each other and vibrate the inner wall of the lower mold 4 to clean impurities, thereby ensuring that the lower mold 4 subsequently presses the raw materials into The molding effect is achieved, and when the magnetic push block 23 moves upward, the internal space of the side groove 20 increases and the air pressure decreases. Then, under the action of the negative pressure at the bottom of the side groove 20, the internal gas of the vent hole 26 is extracted, and the piston ring 29 drives the insert rod 31 to move downward to the initial position. At the same time, since the internal air pressure value of the exhaust hole 32 is continuously reduced to the preset air pressure value set by the pressure valve 33, the pressure valve 33 is opened, and the external air enters the vent hole 26 along the pressure valve 33 for air replenishment, so that each component is restored to its initial state, and the above process is repeated to continue to press and shape the subsequent raw materials, thereby improving the pressing effect and pressing efficiency, and ensuring the processing quality of refractory bricks.

[0075] The device effectively improves the pressing efficiency and processing effect of refractory bricks, has strong adaptability, high stability, simple operation, stable and efficient operation, and when the raw materials enter the pressing chamber 5, the excess raw materials can enter the side groove 20 along the material port 35 for temporary storage, thereby avoiding the accumulation of raw materials and reducing the difficulty of adjusting the raw materials by the operator. After the feeding is completed, the vibration of the insertion rod 31 and the vibration of the lower mold 4 further improve the compactness and levelness of the raw materials on the top of the lower pressing plate 14, thereby ensuring that the quality of the raw materials meets the subsequent pressing requirements; and when the raw materials are pressed, the distance The distance value detected by the sensor 36 is used to indirectly obtain the amount of raw materials on the top of the lower pressure plate 14, and according to the amount of raw materials, the raw materials in the side groove 20 are pushed back to the top of the lower pressure plate 14 for replenishment, thereby ensuring that the amount of raw materials between the lower pressure plate 14 and the pressing block 13 meets the requirements and improves the pressing size and pressing density of the refractory bricks; when the pressing is completed, the refractory bricks can be quickly demolded, thereby improving the demolding efficiency of the refractory bricks, the lower pressure plate 14 and the insert rod 31, avoiding the refractory bricks from being pressed and adhered to the lower pressure plate 14 for a long time to reduce the demolding effect, the processing quality of the refractory bricks is higher, and the size of the refractory bricks meets the requirements.

[0076] Third embodiment

[0078] S1. Pour the raw material into the top of the lower pressing plate 14 inside the pressing chamber 5, and the excess raw material enters the side groove 20 along the material opening 35.

[0079] S2, the controller controls the current of the electromagnetic block 21 to decrease, and the magnetic push block 23 is driven to move downward under the elastic force of the reset spring 22, and the magnetic push block 23 is squeezed and collided with the elastic protrusion 25 and drives the lower mold 4 to vibrate.

[0080] S3. The gas inside the side groove 20 enters the vent hole 26 along the connecting hose 34, and under the action of the gas pressure, drives the insertion rod 31 to extend upward along the vent hole 26 and vibrate the raw material.

[0081] S4. Then the controller controls the pressing block 13 to move downward and squeeze the raw material on the top of the lower pressing plate 14. When the distance value detected by the distance sensor 36 is less than the preset distance value, the controller controls the pressing block 13 to move in the opposite direction to the initial position. The current of the electromagnetic block 21 increases and drives the magnetic push block 23 to move upward. The magnetic push block 23 pushes the top raw material to the top of the lower pressing plate 14 for replenishment.

[0082] S5. When the pressing is completed, the controller controls the electromagnetic block 21 to be powered off, and the magnetic push block 23 is driven to move downward to the maximum distance under the elastic force of the reset spring 22. The plug rod 31 pushes out the top refractory brick, and at the same time the pressure valve 33 opens, and the gas inside the exhaust hole 32 is discharged along the pressure valve 33, so that the refractory brick is separated from the top of the plug rod 31.

[0083] By further limiting the brick pressing method, the brick pressing quality is improved and the brick pressing efficiency is guaranteed.
