Description

Technical Field

[0001] This invention relates to the field of aluminum silicon carbide carbon brick preparation technology, specifically to an energy-saving aluminum silicon carbide carbon brick pressing device. Background Technology

[0002] Alumina silicon carbide carbon bricks are high-performance refractory materials made from alumina, silicon carbide and carbon as the main raw materials, supplemented with phenolic resin or asphalt and other binders, through high-pressure molding and low-temperature drying. The high-pressure molding process of aluminum silicon carbide carbon bricks requires the use of a special pressing device for aluminum silicon carbide carbon bricks.

[0003] As a commonly used refractory material in blast furnaces, silicon carbide alumina bricks are typically made into right-angled trapezoidal shapes to ensure tight interlocking between the bricks and prevent molten iron penetration when applied to specific parts of the blast furnace hearth. This allows the interlocking silicon carbide bricks to fully adapt to the annular sidewall of the blast furnace hearth.

[0004] When pressing right-angled trapezoidal aluminum silicon carbide carbon bricks using existing technology, multiple raw materials are often poured into the bottom mold, and then a hydraulic cylinder is used to move the pressure head, whose bottom is set with an inclined surface, downward. Because the brick blank is a right-angled trapezoid, the unit area pressure borne by the thicker end and the thinner end of the brick blank is different in the pressing groove. Under the same pressure, the density of the thinner end is prone to be higher, while the density of the thicker end may be insufficient, thus creating a large density gradient. After subsequent demolding or heat treatment, uneven release of internal stress will lead to lamellar cracks (parallel cracking), causing a significant decrease in the strength of the pressed aluminum silicon carbide carbon brick, which cannot meet the application requirements. In addition, since only one aluminum silicon carbide carbon brick can be pressed at a time, the pressing efficiency is low and the energy-saving and environmental protection effects are poor.

[0005] Therefore, an energy-saving pressing device for aluminum silicon carbide carbon bricks is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving pressing device for aluminum silicon carbide carbon bricks. By simultaneously applying pressure to the blank from the top and side walls, the pressing area of ​​the blank is effectively increased, and multiple aluminum silicon carbide carbon bricks can be produced in a single pressing process. This solves the problems of large density gradients caused by applying pressure from the inclined side to the blank when pressing right-angled trapezoidal aluminum silicon carbide carbon bricks, resulting in delamination after demolding, and the low pressing efficiency and poor energy-saving and environmental protection effects of only being able to press one aluminum silicon carbide carbon brick at a time. The invention has the advantages of significantly reducing the density gradient of aluminum silicon carbide carbon bricks after pressing, thereby ensuring the pressing quality of aluminum silicon carbide carbon bricks, while effectively improving pressing efficiency and energy-saving and environmental protection effects.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An energy-saving pressing device for aluminum silicon carbide carbon bricks includes a base, a limiting rod, a top seat, and a hydraulic cylinder. It also includes a moving mold, a fixed mold, partitions, reinforcing plates, a pressing mold, and a tension spring. The moving mold is installed at the bottom of the hydraulic cylinder, and the fixed mold is installed on the surface of the base. Four partitions are respectively installed at the four corners inside the fixed mold. Four reinforcing plates are respectively fitted between the four partitions. Four pressing molds are slidably connected to the four reinforcing plates. The tension spring is installed between the reinforcing plates and the pressing molds. During the downward movement of the moving mold driven by the hydraulic cylinder, the moving mold gradually contacts the pressing mold. During the contact between the pressing mold and the moving mold, the pressing mold moves towards the inner side of the corresponding reinforcing plate. The moving mold and the pressing mold apply pressure to the raw material filled between the reinforcing plates from above and sidewalls, respectively.

[0009] Preferably, the moving mold includes a sliding sleeve, a connecting seat, an upper pressing structure, and a side pushing structure. The sliding sleeve is slidably connected to a limiting rod. The connecting seat is installed at the center of the surface of the sliding sleeve. The side pushing structure is installed at the center of the bottom surface of the connecting seat. After the side pushing structure contacts the pressing mold, it continues to move downward and pushes the pressing mold to slide horizontally towards the inner side of the corresponding reinforcing plate. The four upper pressing structures are arranged in a ring array about the side pushing structure and are installed at the bottom of the connecting seat. The upper pressing structures are in contact with the top of the corresponding reinforcing plate when the sliding sleeve moves downward.

[0010] Preferably, the upper pressure structure includes a first bottom column and an upper pressure plate, wherein the first bottom column is installed at the bottom of the connecting seat and the upper pressure plate is installed at the bottom of the first bottom column.

[0011] Preferably, the side-pushing structure includes a second bottom column, an auxiliary plate, and a push block. The second bottom column is installed at the bottom of the connecting seat, the auxiliary plate is installed on the outer periphery of the second bottom column, and the push block is installed at the bottom of the second bottom column.

[0012] Preferably, the push block includes a cross seat and wedge blocks, the cross seat is screwed to the bottom of the second base post, and the four wedge blocks are respectively installed at the four ends of the cross seat.

[0013] Preferably, a recessed groove is provided at the center of the fixed mold, and the recessed groove is located between the four pressing molds. The depth of the recessed groove is the same as the height of the cross seat.

[0014] Preferably, the reinforcing plate includes a U-shaped rib and a bonding plate. The U-shaped rib is bonded between two partitions. The U-shaped rib has a groove on one side close to each other. The two bonding plates are integrally connected to both sides of the U-shaped rib and are bonded to the two partitions respectively.

[0015] Preferably, the pressing mold includes a side pressing mold, a top block, a vertical groove, a docking block, and a positioning groove. The side pressing mold has a placement groove on its side wall. The side pressing mold slides between the corresponding U-shaped rib and the bonding plate. The top block is inserted into the top of the side pressing mold. The groove is adapted to the top block. The top block is connected to the U-shaped rib by a tension spring. The vertical groove and the positioning groove are both opened on the side wall of the side pressing mold, and the positioning groove is located on both sides of the vertical groove. The docking block is installed in the placement groove.

[0016] Preferably, the side mold has a pressing slope on the side away from the placement groove.

[0017] Preferably, the top of the docking block is flush with the bottom of the vertical groove, and positioning blocks adapted to the positioning groove are installed on both sides of the docking block. The side wall of the docking block is provided with a contact slope adapted to the wedge block.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. When applied to the production of aluminum silicon carbide carbon bricks with a right-angled trapezoidal cross-section, this invention, compared to traditional pressing devices that apply pressure to the blank from only one side, applies pressure to the blank from both the top and side walls simultaneously. This effectively increases the pressure-bearing area of ​​the blank, and the side and top pressures are applied synchronously, which can be considered as the blank being subjected to both horizontal and vertical pressures simultaneously. This significantly reduces the density gradient of the pressed aluminum silicon carbide carbon brick blank, thereby ensuring the pressing quality of the aluminum silicon carbide carbon bricks and effectively avoiding subsequent delamination cracking. It also effectively guarantees the strength of the pressed aluminum silicon carbide carbon bricks. Furthermore, by converting the vertical pressure of the hydraulic cylinder into horizontal and vertical pressures, multiple aluminum silicon carbide carbon bricks can be pressed simultaneously in a single operation, effectively improving pressing efficiency and reducing the hydraulic cylinder's return stroke, thus reducing energy consumption and improving the energy-saving and environmentally friendly effect of the aluminum silicon carbide carbon brick pressing operation.

[0020] 2. Through the setting of the moving mold and the pressing mold, the side push structure in the moving mold cooperates with the side pressing mold and the docking block in the pressing mold to convert part of the vertical pressure of the hydraulic cylinder into horizontal thrust. When the upper pressing structure applies pressure to the blank from the top, under the action of the side push structure and the docking block, the side pressing mold applies pressure to the blank from the side, effectively increasing the pressure area of ​​the blank. By simultaneously applying horizontal and vertical pressure, the resultant pressure force on the blank is along the diagonal direction of the blank, which can significantly reduce the density gradient after the aluminum silicon carbide carbon brick is pressed, thereby avoiding the phenomenon of delamination after demolding or heat treatment of aluminum silicon carbide carbon brick, and effectively ensuring the pressing quality and strength of aluminum silicon carbide carbon brick.

[0021] 3. By setting up partitions, reinforcing plates and pressing molds, the inner side of the fixed mold is divided into multiple areas, and with the help of side push structure and docking block, the pressing mold is provided with lateral thrust. When pressing aluminum silicon carbide carbon bricks, multiple aluminum silicon carbide carbon bricks can be pressed at the same time, which greatly improves the pressing efficiency of aluminum silicon carbide carbon bricks, and thus effectively improves the energy-saving and environmental protection effect in the pressing process of aluminum silicon carbide carbon bricks.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 10 This invention provides an energy-saving pressing device for aluminum silicon carbide carbon bricks, the technical solution of which is as follows:

[0035] Reference Figure 1 , Figure 2 and Figure 3 A pressing device for energy-saving aluminum silicon carbide carbon bricks includes a base 1, limiting rods 2, a top seat 3, and a hydraulic cylinder 4. Limiting sleeves are provided at each of the four corners of the base 1 surface. Four limiting rods 2 are respectively inserted into the limiting sleeves at the four corners of the base 1 surface. The top seat 3 is fixedly installed between the tops of the four limiting rods 2. The hydraulic cylinder 4 is installed through the surface of the top seat 3, with its piston rod extending below the top seat 3. The device also includes a moving mold 5, a fixed mold 6, partition plates 7, reinforcing plates 8, a pressing mold 9, and a tension spring 10. The moving mold 5 is installed at the bottom of the hydraulic cylinder 4, and its surface is fixedly installed to the bottom of the piston rod of the hydraulic cylinder 4. The fixed mold 6 is installed on the surface of the base 1, located at the center of the base 1 surface. Four partition plates 7 are respectively installed at the four corners of the inner side of the fixed mold 6. The partition plates 7 are L-shaped with rounded corners. Four reinforcing plates 8 are respectively attached to the four partition plates 7. Between the reinforcing plate 8 and the corner of the partition plate 7, the edge of the reinforcing plate 8 and the partition plate 7 are closely fitted together. The reinforcing plate 8 and the partition plate 7 support each other and form a stable structure inside the fixed mold 6, which can withstand a large horizontal pressure and thus effectively ensure the stability of the aluminum silicon carbide carbon brick pressing process. The four pressing molds 9 are slidably connected to the four reinforcing plates 8 respectively. The tension spring 10 is installed between the reinforcing plate 8 and the pressing mold 9. As the hydraulic cylinder 4 drives the moving mold 5 to move down, the moving mold 5 and the pressing mold 9 gradually come into contact. During the contact between the pressing mold 9 and the moving mold 5, the pressing mold moves to the inner side of the corresponding reinforcing plate 8. The moving mold 5 and the pressing mold 9 apply pressure to the raw material filled between the reinforcing plates 8 from the top and side wall of the reinforcing plate 8 respectively. After the hydraulic cylinder 4 is reset, the pressing mold 9 can be reset under the action of the tension spring 10 so that the billet raw material can continue to be fed into the pressing space formed by the fixed mold 6, the reinforcing plate 8 and the pressing mold 9.

[0036] Reference Figure 4In one embodiment of the present invention, the moving mold 5 specifically includes a sliding sleeve 51, a connecting seat 52, an upper pressing structure 53, and a side pushing structure 54. The sliding sleeve 51 is slidably connected to the limiting rod 2. When the hydraulic cylinder 4 extends and retracts, it drives the sliding sleeve 51 to move along the limiting rod 2, and the sliding sleeve 51 slides relative to the limiting rod 2. The connecting seat 52 is installed at the center of the surface of the sliding sleeve 51. A through groove is opened at the center of the sliding sleeve 51, and the edge of the through groove is stepped. The top of the connecting seat 52 is flush with the top of the sliding sleeve 51. The hydraulic cylinder 4 drives the sliding sleeve 51 to move together through the connecting seat 52. The side pushing structure 54 is installed at the center of the bottom surface of the connecting seat 52, and the side... After the push structure 54 contacts the pressing mold 9, it continues to move downward, pushing the pressing mold 9 to slide horizontally towards the inner side of the corresponding reinforcing plate 8. During this process, the side pressure on the blank is completed, and an inclined surface is formed at the end of the blank, so that the side wall of the pressed blank is in the shape of a right trapezoid. The four upper pressing structures 53 are arranged in a ring array about the side push structure 54 and installed at the bottom of the connecting seat 52. The number of upper pressing structures 53 is the same as the number of partition plates 7 and reinforcing plates 8. When the upper pressing structure 53 moves downward with the sliding sleeve 51, it fits against the top of the corresponding reinforcing plate 8. When the bottom of the upper pressing structure 53 fits against the top of the reinforcing plate 8, the side wall of the upper pressing structure 53 fits against the side wall of the partition plate 7.

[0037] Reference Figure 4 As one embodiment of the present invention, specifically, the upper pressing structure 53 includes a first bottom column 531 and an upper pressing plate 532. The first bottom column 531 is installed at the bottom of the connecting seat 52, and the upper pressing plate 532 is installed at the bottom of the first bottom column 531. The upper pressing plate 532 is made of 42CrMo material and has undergone surface nitriding treatment. When the upper pressing plate 532 moves downward under the action of the hydraulic cylinder 4, both ends of the upper pressing plate 532 are respectively attached to the side walls of the two partition plates 7. One side of the upper pressing plate 532 is combined with the side wall of the reinforcing plate 8, and the other side is attached to the inner wall of the fixed mold 6, thereby pressing the blank into the corresponding space formed by the fixed mold 6, the reinforcing plate 8 and the pressing mold 9, and making the blank be pressed and shaped.

[0038] Reference Figure 5 As one embodiment of the present invention, specifically, the side-pushing structure 54 includes a second bottom column 541, an auxiliary plate 542, and a push block 543. The second bottom column 541 is installed at the bottom of the connecting seat 52, and the auxiliary plate 542 is installed on the outer periphery of the second bottom column 541. During the downward movement, the auxiliary plate 542 moves downward in contact with the vertical groove 93. Through the cooperation of the auxiliary plate 542 and the vertical groove 93, the stability of the aluminum silicon carbide carbon brick pressing process can be further improved. The push block 543 is installed at the bottom of the second bottom column 541. During the vertical downward movement, the push block 543 cooperates with the pressing mold 9. After the push block 543 contacts the pressing mold 9, it continues to move downward, pushing the pressing mold 9 to move horizontally, so that the pressing mold 9 moves horizontally to apply pressure to the end of the blank.

[0039] Reference Figure 6 As one embodiment of the present invention, specifically, the push block 543 includes a cross seat 5431 and a wedge block 5432. The cross seat 5431 is screwed to the bottom of the second bottom post 541. The four wedge blocks 5432 are respectively installed at the four ends of the cross seat 5431. The wedge blocks 5432 act as "press heads" to form a slope at the end of the billet so that the side wall cross section of the pressed billet is a right trapezoidal shape.

[0040] Reference Figure 7 As one embodiment of the present invention, specifically, a recessed groove 61 is provided at the center of the fixed mold 6, and the recessed groove 61 is located between the four pressing molds 9. The depth of the recessed groove 61 is the same as the height of the cross seat 5431. When the cross seat 5431 is in contact with the recessed groove 61, the pressing mold 9 moves to the maximum horizontal displacement.

[0041] Reference Figure 7 As one embodiment of the present invention, specifically, the reinforcing plate 8 includes a U-shaped rib 81 and a bonding plate 82. The U-shaped rib 81 is bonded between two partition plates 7. A groove 811 is formed on one side of the U-shaped rib 81 that is close to each other. The size of the groove 811 is larger than the diameter of the tension spring 10. The end of the tension spring 10 extends into the groove 811. The two bonding plates 82 are integrally connected to both sides of the U-shaped rib 81, and the two bonding plates 82 are bonded to the two partition plates 7 respectively. When the blank is pressed, the bonded partition plates 7 and the bonding plates 82 can withstand the reaction force from the blank, thereby preventing the bonding plates 82 from deforming and causing the straight edge of the aluminum silicon carbide carbon brick to become curved after pressing.

[0042] Reference Figure 8 In one embodiment of the present invention, the pressing mold 9 specifically includes a side pressing mold 91, a top block 92, a vertical groove 93, a connecting block 94, and a positioning groove 95. The side pressing mold 91 has a placement groove 912 on its side wall. The side pressing mold 91 slides between the corresponding U-shaped rib 81 and the bonding plate 82. The bottom surface of the side pressing mold 91 slides against the inner bottom surface of the fixed mold 6. The top block 92 is inserted into the top of the side pressing mold 91. A groove 811 is adapted to the top block 92, and the depth of the groove 811 is greater than the thickness of the top block 92. At the point where the side pressing mold 91 reaches its maximum horizontal displacement... When the top block 92 enters the groove 811, the top block 92 is connected to the U-shaped rib 81 through the tension spring 10. The connection position between the top block 92, the U-shaped rib 81 and the tension spring 10 is fixed with a hook. The end of the tension spring 10 is inserted into the hook for limiting. After the hydraulic cylinder 4 retracts, the tension spring 10 resets and pushes open the top block 92 to reset the side mold 91. The vertical groove 93 and the positioning groove 95 are both opened on the side wall of the side mold 91, and the positioning groove 95 is located on both sides of the vertical groove 93. The bottom of the positioning groove 95 extends into the placement groove 912, and the docking block 94 is installed in the placement groove 912.

[0043] Reference Figure 8 As one embodiment of the present invention, specifically, the side pressing mold 91 is provided with a pressing slope 911 on the side away from the placement groove 912, and the slope of the pressing slope 911 is consistent with the slope of the aluminum silicon carbide carbon brick to be pressed.

[0044] Reference Figure 8 and Figure 9 As one embodiment of the present invention, specifically, the top of the docking block 94 is flush with the bottom of the vertical groove 93, and positioning blocks 941 adapted to the positioning groove 95 are installed on both sides of the docking block 94. The docking block 94 is conveniently placed into the placement groove 912 by the cooperation of the positioning blocks 941 and the positioning groove 95. The side wall of the docking block 94 is provided with a contact slope 942 adapted to the wedge block 5432. The docking block 94 can be replaced to select a suitable docking block 94 with a suitable contact slope 942. When the docking block 94 and the wedge block 5432 with different contact slopes 942 are replaced, the maximum horizontal displacement value of the side pressure mold 91 also changes accordingly.

[0045] Working principle: The mixed silicon carbide carbon brick blanks are pre-quantitatively fed into the "pressing groove" formed by the fixed mold 6, the bonding plate 82 and the side pressing mold 91. Then, the hydraulic cylinder 4 is activated. The hydraulic cylinder 4 drives the sliding sleeve 51, the upper pressing structure 53 and the side pushing structure 54 to move down together through the connecting seat 52. The moving structure first contacts the pressing mold 9. After the push block 543 contacts the positioning block 941, it continues to move down. Under the cooperation of the push block 543 and the positioning block 941, the pressing mold 9 moves horizontally to the side of the corresponding "pressing groove". The tension spring 10 is in a compressed state, thereby applying pressure to the end of the blank to form a slope at the end of the blank. When the bottom of the upper pressing structure 53 contacts the top of the reinforcing plate 8 directly below, the upper pressing structure 53 applies pressure to the blank from above. At the same time, the side pushing component stops moving down, and the pressing mold 9 reaches the maximum horizontal displacement, thus completing the pressing operation of four silicon carbide carbon bricks.

[0046] Specifically, during the downward movement of the moving mold 5, the auxiliary plate 542 in the side push structure 54 first enters the vertical grooves 93 of the side walls of the multiple side pressure molds 91, ensuring the smooth downward movement of the side push structure 54. Then, the push block 543 moves downward and contacts the positioning block 941. The side wall of the wedge block 5432 contacts the contact slope 942 of the positioning block 941. Subsequently, as the push block 543 continues to move downward, through the cooperation of the wedge block 5432 and the contact slope 942, the cross seat 5431, through the wedge block 5432 and... Positioning block 941 pushes side pressure mold 91 to move horizontally. At the same time, upper pressure structure 53 moves downward synchronously. Upper pressure plate 532 presses the loose billet downward. When cross seat 5431 and wedge block 5432 are attached in sink 61, the bottom surface of upper pressure plate 532 is attached to the top of two bonding plates 82 in the corresponding reinforcing plate 8. The billet is subjected to both horizontal and vertical pressure at the same time, thereby avoiding the formation of a large density gradient in the pressed billet and thus ensuring the strength of aluminum silicon carbide carbon brick.

[0047] After pressing is completed, the hydraulic cylinder 4 retracts and resets, the upper pressure plate 532 first separates from the top of the bonding plate 82, and the tension spring 10 then resets and pushes the side pressure mold 91 to separate from the pressed blank.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
