Description

Technical Field

[0001] The present invention relates to the technical field of ceramic processes, and particularly to an extrusion forming mechanism for ceramic blanks. Background Art

[0002] The forming of ceramic blanks is to make the blank into a green body with specified dimensions, shape and certain mechanical strength. The forming methods of traditional ceramic blanks can be divided into manual forming, slip casting forming and pressing forming.

[0003] However, in the process of pressing and forming the existing green body, during the extrusion process of the surface of the clay, it is difficult for the clay to be evenly distributed inside the mold, and holes are likely to appear on the surface of the mold after demolding, affecting the pressing effect. At the same time, due to the irregularity of the mold and the relatively high viscosity of the green body, during the manual demolding process by the operator, the ceramic blank is easily damaged, making the ceramic blank unable to be used normally. Therefore, the present application provides an extrusion forming mechanism for ceramic blanks to meet the requirements. Summary of the Invention

[0010] Optionally, a sliding groove is formed in the top of the hollow plate. A group of positioning holes are formed on both sides of the hollow plate. The sliding plate is slidably connected inside the hollow plate. The grasping rod on one side of the sliding plate is inserted into the positioning hole on one side of the hollow plate.

[0017] By setting the forming component and the oscillating part, when the restraint plate descends in the oscillating cylinder, the oscillating rod at the bottom will continuously collide with the inclined block, and the vibration frequency of the oscillating rod gradually weakens from bottom to top. Therefore, the vibration degree of the clay at the bottom is the largest. By vibrating the bottom clay, the overall clay can be vibrated to a certain extent, so that the green embryo formed by the blended clay and binder can be evenly distributed in the forming component.

[0018] By setting the detachable forming component, when the ceramic embryo in the forming component is formed, the operator first needs to remove the grasping component from the forming component, then remove the bolts fixed between the restraint plate and the sealing plate, and finally remove the sealing plates around the ceramic embryo in turn. The operation is simple, avoiding adhesion between the ceramic embryo and the sealing plate and the restraint plate, ensuring the integrity of the ceramic embryo. At the same time, sealing grooves are provided between adjacent two sealing plates and between adjacent two lining plates, which can not only make the connection between the two sealing plates closer, but also prevent the clay from leaking out between the two sealing plates when the clay is extruded, reducing the probability of embryo damage.

[0041] As Figures 1 to 13As shown in the figure, an embodiment of the present invention provides an extrusion forming mechanism for ceramic green bodies, including an extrusion device 1000. The extrusion device 1000 further includes a moving frame 1. A rotating motor 11 is arranged on one side of the moving frame 1. A support rod 12 is fixedly connected to the output shaft of the rotating motor 11. An extrusion block 2 is fixedly connected to the top of the support rod 12. A grasping component 3 is fixedly connected to the bottom of the support rod 12. A vibration cylinder 5 is arranged on one side of the moving frame 1. A forming component 4 is slidably connected in the vibration cylinder 5. The moving frame 1 is used to control the position change and up-and-down rotation of the extrusion block 2 and the grasping component 3. The grasping component 3 is used to take out the ceramic green body from the vibration cylinder 5. The forming component 4 is used to place the green body formed by the mixed and prepared clay and binder. After the operator pours the clay into the forming component 4, the operator needs to control the moving frame 1 to make the grasping component 3 grasp the forming component 4, so that the forming component 4 can be placed in the vibration cylinder 5 by the grasping component 3. When the forming component 4 enters the vibration cylinder 5, the forming component 4 will vibrate under the action of the vibration cylinder 5, so that the clay inside the forming component 4 is evenly distributed. When the forming component 4 enters the vibration cylinder 5, the grasping component 3 is separated from the forming component 4 and rotates, so that the extrusion block 2 is located below the grasping component 3. Then the extrusion block 2 will move downward under the action of the moving frame 1 and simultaneously extrude the clay in the forming component 4. When the extrusion is completed, the extrusion block 2 is separated from the forming component 4 and rotates in the reverse direction, so that the grasping component 3 is located below the extrusion block 2. Then the grasping component 3 will extend into the vibration cylinder 5 under the action of the moving frame 1. After the vibration is completed, the forming component 4 is taken out. Finally, only the forming component 4 needs to be disassembled to obtain the extruded ceramic green body.

[0042] As an implementation manner in this embodiment, as Figures 2 to 7As shown, the grasping assembly 3 includes a grasping part 31. At the top of the grasping part 31, an auxiliary box 32 is rotatably connected. At the lower part of the grasping part 31, a group of hollow plates 33 with uniform intervals are rotatably connected. The grasping part 31 includes a fixing plate 311. At the top of the fixing plate 311, a limiting column 312 is fixedly connected. At the middle position of the limiting column 312, a rotation limiting groove is opened. On the surface of the limiting column 312, a group of serrated structures in a circular array are arranged. At the bottom edge position of the fixing plate 311, a group of skateboards 313 in a circular array are fixedly connected. On one side of the skateboard 313, a group of grasping rods 314 with uniform intervals are fixedly connected. The bottom of the auxiliary box 32 is a hollow structure. At the top of the hollow structure of the auxiliary box 32, a rotating column 321 is fixedly connected. On one side of the rotating column 321, a first motor 322 is fixedly connected. On the output shaft of the first motor 322, a first gear 323 is fixedly connected. The bottom of the rotating column 321 is rotationally and limitably connected in the limiting column 312. The first gear 323 is meshed with the serrated structure on the side of the limiting column 312. At the top of the hollow plate 33, a chute 331 is opened. On both sides of the hollow plate 33, a group of positioning holes 332 are opened. The skateboard 313 is slidably connected inside the hollow plate 33. The grasping rod 314 on one side of the skateboard 313 is inserted into the positioning hole 332 on one side of the hollow plate 33. The connecting column between the skateboard 313 and the fixing plate 311 is slidably connected in the chute 331. When grasping the molding assembly 4 filled with clay to the vibrating cylinder 5, first, the hollow plate 33 will move above the molding assembly 4 under the action of the moving frame 1. Then, the hollow plate 33 will move downward along the surface of the molding assembly 4. When the hollow plate 33 moves to the bottom of the molding assembly 4, the first motor 322 starts to rotate. When the first motor 322 rotates, the limiting column 312 meshed with the first gear 323 starts to rotate. During the rotation of the limiting column 312, the skateboard 313 will rotate in the hollow plate 33, so that the grasping rod 314 extends out of the positioning hole 332 of the hollow plate 33 and is inserted into the positioning hole 332 on one side of the adjacent hollow plate 33. During the extension of the grasping rod 314, each grasping rod 314 will be respectively inserted between the molding assemblies 4. Then, when the grasping part 31 rises, the grasping rods 314 will rise synchronously. Since the grasping rods 314 are evenly inserted on the molding assembly 4, at this time, the molding assembly 4 will rise synchronously with the grasping rods 314. When the grasping part 31 puts the molding assembly 4 into the vibrating cylinder 5, the first motor 322 rotates in the reverse direction. At this time, the fixing plate 311 will drive the skateboard 313 to move reversely in the hollow plate 33, so that the grasping rods 314 are retracted into the hollow plate 33. At this time, since the connection between the grasping rods 314 and the molding assembly 4 is lost, when the grasping part 31 rises, the molding assembly 4 will still be in the vibrating cylinder 5. When the rotating motor 11 rotates, the positional relationship between the pressing block 2 and the grasping assembly 3 is interchanged. When the pressing block 2 moves downward under the action of the moving frame 1, the pressing block 2 will press the molding assembly 4. After the pressing is completed,The extrusion block 2 will move upward and rotate 180 degrees under the action of the rotating motor 11, and the positional relationship with the grasping component 3 will be interchanged again. When the grasping part 31 moves downward into the vibration cylinder 5 again, the first motor 322 rotates again, so that the grasping rod 314 extends out again and is inserted into the molding component 4. When the grasping part 31 moves upward, the molding component 4 will move upward synchronously with the grasping part 31 until it leaves the vibration cylinder 5.,

[0043] In this embodiment, as Figures 2 to 7 shown, when the grasping part 31 transfers the molding component 4, the grasping rods 314 on the four sliding plates 313 will be evenly distributed on the molding component 4, making the molding component 4 more stable during the movement, avoiding large-amplitude shaking and causing gaps in the ceramic blank. At the same time, through the rotation of the rotating motor 11 and the movement of the moving frame 1, the extrusion and transfer of the ceramic blank can also be realized.,

[0044] As an implementation manner in this embodiment, as Figures 7 to 13As shown, the forming component 4 includes a set of annularly arrayed sealing plates 41. There are four sealing plates 41. Adjacent two sealing plates 41 are slidably connected through a sealing groove. A set of evenly spaced oscillation grooves 411 are formed on the sealing plate 41. A binding plate 43 is sleeved at the bottom of the set of annularly arrayed sealing plates 41. A hollow plate 33 is slidably connected between two sealing plates 41. An inner lining plate is installed inside the sealing plate 41. There is a gap between the inner lining plate and the sealing plate 41. Springs are installed in the gap between the inner lining plate and the sealing plate 41. Adjacent two inner lining plates are also slidably connected through a sealing groove. An oscillation rod 42 is slidably connected in the oscillation groove 411 on the sealing plate 41. A baffle is fixedly connected to the oscillation rod 42. An oscillation head 421 is fixedly connected to one end of the oscillation rod 42. A first spring 422 is arranged between the sealing plate 41 and the baffle. The other end of the oscillation rod 42 is provided with an inclined surface. A grasping rod 314 is inserted between the upper and lower adjacent oscillation rods 42. The end of the oscillation head 421 abuts against the outer side of the inner lining plate. A set of annularly arrayed guiding grooves 51 are formed on the inner wall of the oscillation cylinder 5. An oscillation part 52 is fixedly connected in the guiding groove 51. The inner wall of the oscillation cylinder 5 is connected to the side surface of the hollow plate 33. The end of the oscillation rod 42 with the inclined surface is slidably connected to one side of the oscillation part 52. The oscillation part 52 includes a mounting plate 521. A set of evenly spaced one-way grooves 522 are fixedly connected to one side of the mounting plate 521. An inclined block 523 is rotatably connected in the one-way groove 522. A torsion spring 524 is arranged between the inclined block 523 and the mounting plate 521. When the grasping component 3 grasps the forming component 4, first, the operator needs to place the binder on the binding plate 43, then insert the four sealing plates 41 in sequence and fix them to the binding plate 43 through bolts, and make adjacent two sealing plates 41 connected to each other. Then pour the clay into it. Finally, when the grasping component 3 is sleeved on the sealing plate 41 and the grasping rod 314 extends, the extended grasping rod 314 will be inserted between the adjacent two oscillation rods 42. When the grasping component 3 ascends, due to the support of the grasping rod 314 at the bottom of the oscillation rod 42, at this time, the oscillation rod 42 will drive the sealing plate 41 and the binding plate 43 to ascend synchronously. When the grasping component 3 drives the binding plate 43 into the oscillation cylinder 5, the oscillation rod 42 will contact the inclined block 523. When the oscillation rod 42 contacts the inclined block 523 from top to bottom, since the bottom of the inclined block 523 is supported by the one-way groove 522, at this time, the oscillation rod 42 will horizontally move under the action of the inclined block 523, so that the oscillation head 421 impacts on the inner lining plate of the sealing plate 41. Since the green embryo in the inner lining plate has a certain softness, while the inner lining plate vibrates under the impact of the oscillation head 421, it drives the springs on the inner wall to be quickly compressed and rebound, vibrating the inner lining plate, so that the green embryo in the inner lining plate will be more evenly distributed. When the inclined surface of the oscillation rod 42 is separated from the inclined block 523, the compressed first spring 422 will elongate, so that the oscillation rod 42 returns to its original position. As the binding plate 43 continuously descends,The oscillating rod 42 will contact different inclined blocks 523. When the restraint plate 43 is at the bottom of the oscillating cylinder 5, the oscillating head 421 stops vibrating. When the forming assembly 4 gradually moves upward away from the oscillating cylinder 5 under the action of the grasping assembly 3, the oscillating rod 42 will also move upward synchronously and contact the inclined block 523 from bottom to top. At this time, since there is no support at the top of the inclined block 523, the inclined block 523 will rotate upward under the push of the oscillating rod 42, allowing the oscillating rod 42 to pass smoothly. When the oscillating rod 42 separates from the inclined block 523, the compressed torsion spring 524 will be released and restore the inclined block 523.,

[0045] In this embodiment, as Figures 7 to 13 shown, when the restraint plate 43 descends in the oscillating cylinder 5, the lowermost oscillating rod 42 will continuously collide with the inclined block 523. The vibration frequency of the oscillating rod 42 gradually weakens from bottom to top. Therefore, the vibration degree of the clay at the bottom in the innermost lining plate inside the sealing plate 41 is the greatest. By vibrating the clay at the bottom, the overall clay can be vibrated to a certain extent, so that the green embryo can be evenly distributed in the forming assembly 4. On the other hand, by setting the detachable forming assembly 4, after the ceramic embryo in the forming assembly 4 is formed, the operator first needs to remove the grasping assembly 3 from the forming assembly 4, then remove the bolts fixed between the restraint plate 43 and the sealing plate 41, and finally remove the sealing plate 41 around the extruded ceramic embryo in sequence. The operation is simple, avoiding adhesion between the ceramic embryo and the sealing plate 41 and the restraint plate 43, ensuring the integrity of the ceramic embryo. Moreover, sealing grooves are provided between adjacent two sealing plates 41 and between adjacent two lining plates, which can not only make the connection between the two sealing plates 41 tighter, but also prevent the clay from leaking out between the two sealing plates 41 when the clay is extruded. At the same time, the material of the lining plate is set as smooth tungsten carbide steel bonded hard alloy on the surface, which has the advantages of non-sticking to the mold, high mold life, and good anti-adhesion, preventing adhesion when the ceramic embryo is taken out and facilitating demolding.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] First, the operator pours the clay into the forming assembly 4 (as Figure 8As shown in the figure, the operator then controls the movement of the moving frame 1 to grab the grabbing component 3 on the forming component 4, so that the forming component 4 is placed in the vibrating cylinder 5 by the grabbing component 3. When the forming component 4 enters the vibrating cylinder 5, the forming component 4 will vibrate under the action of the vibrating cylinder 5, making the clay inside the forming component 4 evenly distributed. When the forming component 4 enters the vibrating cylinder 5, the grabbing component 3 separates from the forming component 4 and rotates, so that the extrusion block 2 is located below the grabbing component 3. Then the extrusion block 2 will move downward under the action of the moving frame 1 and simultaneously extrude the clay in the forming component 4. When the extrusion is completed, the extrusion block 2 separates from the forming component 4 and rotates in the reverse direction, so that the grabbing component 3 is located below the extrusion block 2. Then the grabbing component 3 will extend into the vibrating cylinder 5 under the action of the moving frame 1 and take out the forming component 4. Finally, only the forming component 4 needs to be disassembled to obtain the ceramic blank after extrusion molding.

[0048] Specifically: when the grabbing component 3 grabs the forming component 4 filled with clay to the vibrating cylinder 5, first, the hollow plate 33 will move to the upper part of the forming component 4 under the action of the moving frame 1. Then the hollow plate 33 will move downward along the outer surface of the forming component 4. When the hollow plate 33 moves to the bottom of the forming component 4, the first motor 322 starts to rotate, driving the limiting column 312 engaged with the first gear 323 to start rotating. During the rotation of the limiting column 312, the sliding plate 313 will rotate in the hollow plate 33, so that the grabbing rod 314 extends out of the positioning hole 332 of the hollow plate 33 and inserts into the positioning hole 332 on one side of the adjacent hollow plate 33. During the extension of the grabbing rod 314, each grabbing rod 314 will be inserted between the forming components 4 respectively. Then, when the grabbing part 31 rises, the grabbing rod 314 will rise synchronously. Since the grabbing rod 314 is evenly inserted on the forming component 4, at this time, the forming component 4 will rise synchronously with the grabbing rod 314;

[0049] When the grabbing part 31 puts the forming component 4 into the vibrating cylinder 5, at this time, the vibrating rod 42 contacts the inclined block 523 from top to bottom. Since the bottom of the inclined block 523 is supported by the one-way groove 522, at this time, the vibrating rod 42 will move horizontally under the action of the inclined block 523, so that the vibrating head 421 impacts the inner lining plate on the inner side of the sealing plate 41. Since the unextruded clay has a certain softness, while the inner lining plate vibrates under the impact of the vibrating head 421, the spring on the inner wall is quickly compressed and rebounds, vibrating the inner lining plate, making the inside of the green embryo in the inner lining plate more evenly distributed. When the inclined surface of the vibrating rod 42 separates from the inclined block 523, the compressed first spring 422 will elongate, making the vibrating rod 42 return to its original position. As the restraint plate 43 continuously descends, the vibrating rod 42 will contact different inclined blocks 523. When the restraint plate 43 is located at the bottom of the vibrating cylinder 5, the vibrating head 421 stops vibrating.

[0050] When the binding plate 43 descends in the vibration cylinder 5, the lowermost vibration rod 42 will continuously collide with the inclined block 523. The vibration frequency of the vibration rod 42 gradually weakens from bottom to top. Therefore, the clay at the bottom in the inner lining plate inside the sealing plate 41 is subjected to the greatest degree of vibration. By vibrating the clay at the bottom, the overall clay can be vibrated to a certain extent, so that the green embryos can be evenly distributed in the forming assembly 4. On the other hand, by setting the detachable forming assembly 4, when the ceramic embryo in the forming assembly 4 is formed, the operator first needs to remove the grasping assembly 3 from the forming assembly 4, then remove the bolts fixed between the binding plate 43 and the sealing plate 41, and finally remove the sealing plates 41 around the ceramic embryo in sequence. The operation is simple, avoiding the adhesion between the ceramic embryo and the sealing plate 41 and the binding plate 43, ensuring the integrity of the ceramic embryo, reducing the probability of embryo damage. Moreover, sealing grooves are provided between adjacent two sealing plates 41 and between adjacent two inner lining plates, which can not only make the connection between the two sealing plates 41 tighter, but also prevent the clay from leaking out between the two sealing plates 41 when the clay is extruded. The first motor 322 rotates in the reverse direction. At this time, the fixing plate 311 will drive the sliding plate 313 to move in the reverse direction in the hollow plate 33, so that the grasping rod 314 is retracted into the hollow plate 33. At this time, since the grasping rod 314 is disconnected from the forming assembly 4, when the grasping part 31 rises, the forming assembly 4 will still be in the vibration cylinder 5.

[0051] Subsequently, the extrusion block 2 moves downward under the action of the moving frame 1, and the extrusion block 2 will extrude the forming assembly 4 until the embryo is formed. After the extrusion is completed, the extrusion block 2 moves upward through the moving frame 1 and rotates 180 degrees under the action of the rotating motor 11, and the positional relationship with the grasping assembly 3 is interchanged. When the grasping part 31 moves downward into the vibration cylinder 5 again, the first motor 322 rotates again, so that the grasping rod 314 extends out again and is inserted into the forming assembly 4. When the grasping part 31 moves upward, the forming assembly 4 will move upward synchronously with the grasping part 31 until it leaves the vibration cylinder 5. When the grasping part 31 transfers the forming assembly 4, the grasping rods 314 on the four sliding plates 313 will be evenly distributed on the forming assembly 4, making the forming assembly 4 more stable during the movement and avoiding large-amplitude shaking that causes gaps in the ceramic embryo.

[0052] When the forming assembly 4 gradually moves upward away from the vibration cylinder 5 under the action of the grasping assembly 3, the vibration rod 42 will also move upward synchronously and contact the inclined block 523 from bottom to top. At this time, since there is no support at the top of the inclined block 523, the inclined block 523 will rotate upward under the push of the vibration rod 42, so that the vibration rod 42 can pass through smoothly. When the vibration rod 42 separates from the inclined block 523, the compressed torsion spring 524 will be released and the inclined block 523 will return to its original state;

[0053] Furthermore: By rotating the motor 11, the extrusion and transfer of the ceramic blank can be achieved. When the grasping assembly 3 grasps the forming assembly 4, first, the operator needs to sequentially insert and bolt the four sealing plates 41 to the restraint plate 43 and connect the adjacent two sealing plates 41. Then, pour the clay into it. Finally, when the grasping assembly 3 is sleeved on the sealing plate 41 and the grasping rod 314 extends, the extended grasping rod 314 will be inserted between the adjacent two oscillating rods 42. When the grasping assembly 3 rises, since the bottom of the oscillating rod 42 is supported by the grasping rod 314, the oscillating rod 42 will drive the sealing plate 41 and the restraint plate 43 to rise synchronously. When the grasping assembly 3 brings the restraint plate 43 into the oscillating cylinder 5, the oscillating rod 42 will contact the inclined block 523.

[0054] When the oscillating rod 42 contacts the inclined block 523 from top to bottom, since the bottom of the inclined block 523 is supported by the one-way groove 522, the oscillating rod 42 will horizontally move under the action of the inclined block 523, so that the oscillating head 421 impacts on the inner lining plate of the sealing plate 41. Since the clay has a certain softness, while the inner lining plate vibrates under the impact of the oscillating head 421, it drives the springs on the inner wall to quickly compress and rebound, vibrating the inner lining plate and making the distribution of the green embryo inside the inner lining plate more uniform. When the inclined surface of the oscillating rod 42 separates from the inclined block 523, the compressed first spring 422 will elongate, making the oscillating rod 42 return to its original position. As the restraint plate 43 continuously descends, the oscillating rod 42 will contact different inclined blocks 523. When the restraint plate 43 is at the bottom of the oscillating cylinder 5, the oscillating head 421 stops vibrating. When the forming assembly 4 gradually moves upward and away from the oscillating cylinder 5 under the action of the grasping assembly 3, the oscillating rod 42 will also move upward synchronously and contact the inclined block 523 from bottom to top.

[0055] At this time, since there is no support at the top of the inclined block 523, the inclined block 523 will rotate upward under the push of the shock rod 42, allowing the shock rod 42 to pass smoothly. When the shock rod 42 separates from the inclined block 523, the compressed torsion spring 524 will be released and restore the inclined block 523. When the restraint plate 43 descends in the shock cylinder 5, the lowermost shock rod 42 will continuously collide with the inclined block 523. The vibration frequency of the shock rod 42 gradually weakens from bottom to top. Therefore, the clay at the bottom of the inner lining plate inside the sealing plate 41 is subjected to the greatest degree of vibration. By vibrating the bottom clay, the overall clay can be vibrated to a certain extent, so that the green embryos can be evenly distributed in the forming assembly 4. On the other hand, by setting the detachable forming assembly 4, after the ceramic embryo in the forming assembly 4 is formed, the operator first needs to remove the grasping assembly 3 from the forming assembly 4, then remove the bolts fixed between the restraint plate 43 and the sealing plate 41, and finally remove the sealing plate 41 and the inner lining plate around the extruded ceramic embryo in sequence. The operation is simple, avoiding the adhesion between the ceramic embryo and the sealing plate 41 and the restraint plate 43, ensuring the integrity of the ceramic embryo, reducing the probability of embryo damage. Moreover, sealing grooves are provided between adjacent two sealing plates 41 and between adjacent two inner lining plates, which can not only make the connection between the two sealing plates 41 tighter, but also prevent the clay from leaking out between the two sealing plates 41 when the clay is being extruded.
