Description

Technical Field

[0001] This application relates to the technical field of refractory brick forming, and particularly relates to a forming device for processing refractory bricks. Background Art

[0002] Refractory bricks, abbreviated as fire bricks, refer to refractory materials with a certain shape and size. They can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical actions at high temperatures. When processing refractory bricks, different types of raw material powders need to be evenly mixed together first, then the mixed powder is loaded into a mold, and then the powder is pressed and formed by a press to obtain a brick blank of the refractory brick. Then, the brick blank needs to be fired to obtain the finished refractory brick.

[0003] In the process of stamping and forming traditional refractory bricks, since the stamping is carried out from top to bottom, after the refractory bricks are formed, the refractory brick materials on the upper part are under greater pressure, so the density of the upper refractory bricks is large, while the density of the lower refractory bricks is small, forming a density gradient, resulting in uneven internal density of the refractory bricks. And the uneven density will cause internal stress in the refractory bricks. Therefore, cracks are easily generated inside the refractory bricks after forming. Especially after firing, the refractory bricks are very easy to crack, which not only reduces the forming quality of the refractory bricks, but also reduces the product qualification rate. Moreover, since the refractory brick materials are very tightly fitted to the mold after stamping, it is not only difficult to demold, and the demolding process depends on manual operation, with low efficiency and poor safety. And when demolding, due to the friction between the formed refractory bricks and the inner wall of the mold, both the surface of the refractory bricks and the inner wall of the mold will be worn, thus resulting in a reduction in the dimensional accuracy of the refractory bricks.

[0004] Therefore, we propose a forming device for processing refractory bricks to solve the above problems. Summary of the Invention

Magnets are provided at the positions where the lifting rod contacts the bottom of the pressing block.

[0022] Compared with the prior art, the advantages of this application are as follows:

[0023] (1) By providing a composite mold, which includes an upper mold, a lower mold and a side mold, the upper mold, the lower mold and the side mold can all stamp the refractory brick during molding, so that the refractory brick can be stamped and formed in all directions, the refractory brick can be formed more uniformly, the density gradient can be reduced, and thus the phenomenon of cracking can be reduced, improving the forming quality of the refractory brick.

[0024] (2) By providing a commutation stamping member inside the side mold, when the mounting block moves downward, it drives the pressing block to move downward together. After the extrusion block is squeezed by the pressing block, it drives the second commutation block to move downward, the second spring is compressed, and the second commutation block squeezes the first commutation block to move toward the refractory brick, and the first commutation block drives the first spring to be stretched, thereby driving the side pressing blocks in four directions to move toward the refractory brick at the same time, realizing the stamping in the horizontal direction.

[0025] (3) By providing a lower stamping member inside the lower mold, when the pressing block and the upper pressing block move downward, they will squeeze the extrusion block and the refractory brick raw material. At this time, it can drive the side mold and the lower mold to descend. When the lower mold descends, the pressing block moves upward relative to the lower mold. Therefore, the pressing block will generate an upward impact force on the refractory brick raw material, thereby realizing the stamping from bottom to top.

[0026] (4) By setting a fixed separator between adjacent side molds, when the electromagnet is energized, a repulsive force is generated between the electromagnet and the permanent magnet, driving the permanent magnet and the clamping block to move, compressing Spring Four, thereby driving the clamping block to disengage from the card slot. At this time, the fixed connection relationship between Fixed Block One and Fixed Block Two is released, so the fixed connection between the side molds is released. Then, after the side molds are subjected to the repulsive force, they move outward and away from each other on the lower mold through the sliding blocks and sliding grooves, compressing Spring Five, which facilitates the unloading of the formed refractory bricks. At the same time, it can avoid friction during unloading, reduce the wear on the surface of the refractory bricks, and improve the dimensional accuracy of the refractory bricks.

[0027] (5) By setting heating sheets on the side pressing block and the lower pressing block, the heating sheets can control the temperature between 200 - 300 degrees. Through heating, the refractory brick material can be softened, reducing the hardness of the material, making the material easier to form, and being able to better fill every corner of the mold during the stamping process, making the forming more compact and the forming effect better. Heating can also make the density of the formed refractory bricks more uniform, further reducing the density gradient, thereby further reducing the internal stress of the refractory bricks and further reducing the phenomenon of cracks and deformation in the refractory bricks after forming, and further improving the product quality and product qualification rate of the refractory bricks.

[0028] (6) By setting a jacking member and a jacking rod, the jacking member drives the jacking rod to rise until it contacts the bottom of the lower pressing block. Then, the jacking rod is adsorbed to the lower pressing block by a magnet, and the jacking rod continues to rise, driving the lower pressing block and the refractory brick on it to rise, facilitating the removal of the refractory brick.

[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] Embodiment 1:

[0041] The present invention provides a forming device for processing refractory bricks. Please refer to Figures 1 - 8, including a stamping machine tool 1, a die cushion 2 fixedly installed on the stamping machine tool 1, and a blanking table 3 arranged outside the stamping machine tool 1. A number of sets of composite dies 4 are arranged on the stamping machine tool 1. The composite die 4 includes an upper die 41, a lower die 42 and a side die 43. When forming, the upper die 41, the lower die 42 and the side die 43 can all stamp the refractory brick, so that the refractory brick can be stamped and formed in all directions, the refractory brick can be formed more evenly, the density gradient can be reduced, and the phenomenon of cracking can be reduced, thereby improving the forming quality of the refractory brick. A reversing stamping part 5 is arranged in the side die 43. The reversing stamping part 5 can convert the vertical punching force into a horizontal punching force, and synchronously stamp and form the refractory brick from the side during vertical stamping. A lower stamping part 6 is arranged in the lower die 42. When the upper die 41 descends for stamping, it can squeeze and drive the lower die 42 to move together, and synchronously stamp and form the refractory brick from the bottom during vertical stamping. A fixed separating part 7 is arranged between adjacent side dies 43. The fixed separating part 7 can separate the side die 43 after the refractory brick is formed, preventing the formed refractory brick from being adsorbed on the side die 43 and being difficult to take out due to the extrusion force during stamping, so that the blanking is more convenient and efficient. At the same time, it can avoid the friction between the refractory brick and the side die 43 during blanking, resulting in wear of the side die 43 and the refractory brick, protecting the side die 43 and also improving the forming quality of the refractory brick.

[0042] The upper die 41 includes a mounting block 411, an upper pressing block 412 and a pressing block 413; the mounting block 411 is fixedly connected to the die cushion 2, the upper pressing block 412 is fixedly connected to the bottom of the mounting block 411, a plurality of pressing blocks 413 are provided and are respectively fixedly connected to the four sides of the mounting block 411, and the extrusion block 509 corresponds to the position of the pressing block 413.

[0043] The die cushion 2 drives the mounting block 411 and the upper pressing block 412 to move downward, so as to realize stamping from top to bottom.

[0044] The commutation stamping part 5 includes a working cavity 501, a side pressing block 502, a first commutation block 503, a first spring 504, a sliding groove 505, a sliding block 506, a second commutation block 507, a second spring 508, and an extrusion block 509; the working cavity 501 is opened on one side where the side molds 43 are close to each other, the side pressing block 502 is hermetically and slidably connected to the working cavity 501, the first commutation block 503 is fixedly connected to the side pressing block 502, the first spring 504 is fixedly connected between the side pressing block 502 and the working cavity 501, the sliding groove 505 is opened on the side wall of the working cavity 501 away from the side pressing block 502, the sliding block 506 is slidably connected to the sliding groove 505, the second commutation block 507 is fixedly connected to the sliding block 506, bevels are opened on the sides of the first commutation block 503 and the second commutation block 507 close to each other, the first commutation block 503 and the second commutation block 507 are in extrusion fit with each other, the second spring 508 is fixedly connected between the sliding block 506 and the bottom wall of the sliding groove 505, the extrusion block 509 is fixedly connected to the top of the second commutation block 507, and the extrusion block 509 penetrates through the top of the side mold 43 and is slidably connected to the side mold 43 (it should be noted here that the lengths of the long side and the short side of the side mold 43 are different, and the internal parts are only different in length, and other settings and working principles are the same).

[0045] When the installation block 411 moves downward, it drives the pressing block 413 to move downward together. After the extrusion block 509 is extruded by the pressing block 413, it drives the second commutation block 507 to move downward, the second spring 508 is compressed, the second commutation block 507 extrudes the first commutation block 503 to move in the direction of the refractory brick, and the first commutation block 503 drives the first spring 504 to be stretched, so as to drive the side pressing blocks 502 in four directions to move towards the refractory brick at the same time, realizing horizontal stamping. Until the pressing block 413 drops to be flush with the upper surface of the side mold 43, at this time, the lower surface of the upper pressing block 412 is flush with the upper surface of the side pressing block 502, and at the same time, the outer surface of the side pressing block 502 is flush with the surface of the side mold 43.

[0046] The lower stamping part 6 includes a lower pressing block 601, a bottom plate 602, a third spring 603, and a limiting block 604; a backing plate 8 is arranged on the stamping machine tool 1, the lower pressing block 601 is hermetically and slidably connected to the lower mold 42, the bottom plate 602 is fixedly connected to the backing plate 8, the third spring 603 is fixedly connected between the lower mold 42 and the bottom plate 602, and two limiting blocks 604 are respectively fixedly connected to the lower mold 42 and the bottom plate 602.

[0047] When the pressing block 413 and the upper pressing block 412 move downward, they will squeeze the extrusion block 509 and the refractory brick raw material. The extrusion block 509 will transmit the extrusion force to the lower die 42 through the side die 43. Therefore, at this time, the side die 43 and the lower die 42 can be driven to descend. When the lower die 42 descends, the lower pressing block 601 will move upward relative to the lower die 42. Therefore, the lower pressing block 601 will generate an upward impact force on the refractory brick raw material, so as to realize the stamping from bottom to top until the two limit blocks 604 contact for limiting. At this time, the upper surface of the lower pressing block 601 is flush with the lower surface of the side pressing block 502.

[0048] Heating sheets 9 and temperature sensors 10 are arranged on the sides of the side pressing block 502 and the lower pressing block 601 away from the upper die 41. The heating sheets 9 and the temperature sensors 10 are both connected to the controller for control.

[0049] The heating sheet 9 can control the temperature between 200 - 300 degrees. Through heating, the refractory brick material can be softened, the hardness of the material can be reduced, making the material easier to form. And during the stamping process, it can better fill every corner of the mold, making the forming more compact and the forming effect better. Heating can also make the density of the formed refractory brick more uniform, further reducing the density gradient, thus further reducing the internal stress of the refractory brick and further reducing the phenomena of cracks and deformation in the formed refractory brick, and further improving the product quality and product qualification rate of the refractory brick.

[0050] The fixed separation part 7 includes a first fixed block 701, a second fixed block 702, a card slot 703, a moving slot 704, a clamping block 705, an electromagnet 706, a permanent magnet 707, a moving block 708, a mounting bracket 709 and a fourth spring 710; the first fixed block 701 and the second fixed block 702 are respectively fixedly connected to the adjacent side die 43. The card slot 703 is opened on the first fixed block 701, the moving slot 704 is opened on the second fixed block 702, the clamping block 705 is slidably connected to both the moving slot 704 and the card slot 703. The electromagnet 706 is fixedly connected to the first fixed block 701, the permanent magnet 707 is fixedly connected to the clamping block 705. After the electromagnet 706 is energized, the magnetic poles of the sides close to the permanent magnet 707 are the same. The moving block 708 is fixedly connected to the permanent magnet 707, the mounting bracket 709 is fixedly connected to the top of the second fixed block 702, and the fourth spring 710 is fixedly connected between the moving block 708 and the mounting bracket 709. The fixed separation part 7 further includes a mounting plate 711, a fifth spring 712, a sliding block 713 and a sliding slot 714; the mounting plate 711 is fixedly connected to the lower die 42, the fifth spring 712 is fixedly connected between the side die 43 and the mounting plate 711, the sliding block 713 is fixedly connected to the bottom of the side die 43, the sliding slot 714 is opened on the lower die 42, and the sliding block 713 is slidably connected to the sliding slot 714.

[0051] After the electromagnet 706 is energized, a repulsive force is generated between it and the permanent magnet 707, which drives the permanent magnet 707 and the block 705 to move, and the spring four 710 is compressed, thereby driving the block 705 to disengage from the slot 703. At this time, the fixed connection between the fixed block 1 701 and the fixed block 2 702 is released, so the fixed connection between the side mold 43 is released, and the repulsive force between the electromagnet 706 and the permanent magnet 707 will act on the side mold 43. Therefore, after the side mold 43 is subjected to the repulsive force, it moves outward on the lower mold 42 through the sliding block 713 and the sliding slot 714 to expand away from each other, and the spring five 712 is compressed, which facilitates the unloading of the formed refractory bricks. At the same time, it can avoid friction during unloading, reduce the wear on the surface of the refractory bricks, and improve the dimensional accuracy of the refractory bricks (it should be noted that the elasticity of the spring five 712 is greater than the elasticity of the spring four 710, and the repulsive force between the electromagnet 706 and the permanent magnet 707 is greater than the sum of the elastic forces of the spring four 710 and the spring five 712).

[0052] A moving part 11 is provided on the stamping machine 1, and the pad 8 is slidably connected to the moving part 11. The moving part 11 can drive the pad 8 and the device thereon to move between the stamping machine 1 and the unloading table 3, and can remain in a fixed state during mobile stamping work and unloading (this is the prior art and will not be elaborated on here).

[0053] A lifting member is provided inside the unloading platform 3 (this is the prior art, such as a cylinder, which is not shown in the figure and will not be elaborated on here). The output end of the lifting member is fixedly connected to a lifting rod 12. The lifting rod 12 passes through the pad 8, the bottom plate 602 and the lower mold 42 and contacts the bottom of the lower pressing block 601. Magnets are provided at the positions where the lifting rod 12 contacts the bottom of the lower pressing block 601, and the magnets attract each other. During unloading, the lifting member drives the lifting rod 12 to rise until it contacts the bottom of the lower pressing block 601, and then the lifting rod 12 and the lower pressing block 601 are adsorbed together by the magnet. The lifting rod 12 continues to rise, driving the lower pressing block 601 and the refractory bricks thereon to rise, so as to facilitate the removal of the refractory bricks.

[0054] Working principle: Turn on the heating plate 9 in advance, and then mix the raw material powder of the refractory bricks evenly and put them into the composite mold 4. The heating plate 9 heats the raw material of the refractory bricks and controls the temperature between 200-300 degrees to soften the material and reduce the hardness of the material, which is convenient for subsequent stamping and forming;

[0055] After the material is heated, the punching machine 1 works, and the die pad 2 drives the mounting block 411 and the upper pressing block 412 to move downward, thereby realizing punching from top to bottom;

[0056] When the installation block 411 moves downward, it drives the pressing block 413 to move downward together. After the extrusion block 509 is extruded by the pressing block 413, it drives the second reversing block 507 to move downward, and the second spring 508 is compressed. The second reversing block 507 extrudes the first reversing block 503 to move towards the refractory brick. The first reversing block 503 drives the first spring 504 to be stretched, thereby driving the side pressing blocks 502 in four directions to move towards the refractory brick simultaneously, realizing the stamping in the horizontal direction;

[0057] When the pressing block 413 and the upper pressing block 412 move downward, they will extrude the extrusion block 509 and the refractory brick raw material. At this time, it can drive the side mold 43 and the lower mold 42 to descend. When the lower mold 42 descends, the lower pressing block 601 moves upward relative to the lower mold 42. Therefore, the lower pressing block 601 will generate an upward impact force on the refractory brick raw material, thus realizing the stamping from bottom to top;

[0058] When the pressing block 413 descends to be flush with the upper surface of the side mold 43 and the two limit blocks 604 come into contact for limiting, at this time, the moving stroke of the upper pressing block 412 ends. The lower surface of the upper pressing block 412 is flush with the upper surface of the side pressing block 502. The outer surface of the side pressing block 502 is flush with the surface of the side mold 43. The upper surface of the lower pressing block 601 is flush with the lower surface of the side pressing block 502. The size of the space enclosed by the upper pressing block 412, the side pressing block 502, and the lower pressing block 601 is the size of the refractory brick. The upper pressing block 412, the side pressing block 502, and the lower pressing block 601 can perform stamping and forming on the refractory brick in all directions, enabling the refractory brick to be formed more evenly, reducing the density gradient inside the refractory brick, thereby reducing the phenomenon of cracking and improving the forming quality of the refractory brick;

[0059] At the same time, heating by the heating sheet 9 can soften the refractory brick material, reduce the hardness of the material, make the material easier to form, and can better fill every corner of the mold during the stamping process, making the forming tighter and the forming effect better. Heating can also make the density of the formed refractory brick more uniform, further reducing the density gradient inside the refractory brick, thereby further reducing the internal stress of the refractory brick and further reducing the phenomenon of cracks and deformation in the formed refractory brick, and further improving the product quality and product qualification rate of the refractory brick;

[0060] After the refractory brick is formed, the electromagnet 706 is activated. After the electromagnet 706 is energized, a repulsive force is generated between the electromagnet 706 and the permanent magnet 707, driving the permanent magnet 707 and the clamping block 705 to move. The fourth spring 710 is compressed, thereby driving the clamping block 705 to disengage from the clamping groove 703. At this time, the fixed connection relationship between the first fixing block 701 and the second fixing block 702 is released. Therefore, the fixed connection between the side molds 43 is released. Then, after the side molds 43 are subjected to the repulsive force, they move outward and away from each other on the lower mold 42 through the sliding blocks 713 and the sliding grooves 714. The fifth spring 712 is compressed, which facilitates the unloading of the formed refractory brick. At the same time, it can avoid friction during unloading, reduce the wear on the surface of the refractory brick, and improve the dimensional accuracy of the refractory brick;

[0061] After that, the upper pressing block 412 rises and resets. The moving member 11 moves the device from the stamping machine tool 1 to the unloading table 3. Then, the jacking member drives the jacking rod 12 to rise until it contacts the bottom of the lower pressing block 601, and then adsorbs the jacking rod 12 and the lower pressing block 601 together through the magnet. The jacking rod 12 continues to rise, driving the lower pressing block 601 and the refractory brick thereon to rise, facilitating the removal of the refractory brick;

[0062] After the upper pressing block 412 rises and resets, under the elastic action of the first spring 504 and the second spring 508, the side pressing block 502 and the extrusion block 509 are driven to reset;

[0063] After the refractory brick is taken out, the composite mold 4 is cleaned. Then, the electromagnet 706 is powered off. Under the elastic force of the fifth spring 712, the side molds 43 are driven to move and reset until the clamping block 705 is reinserted into the clamping groove 703, and the side molds 43 are fixedly connected together again. At the same time, the jacking rod 12 descends and resets, driving the lower pressing block 601 to move downward and reset.
