Description

Technical Field

[0001] This invention relates to the field of ceramic forming equipment technology, specifically to an adaptive multi-station ceramic dry pressing forming equipment. Background Technology

[0002] Ceramic dry pressing is a process in which ceramic powder is filled into a mold cavity and then compacted by mechanical pressure to form a blank with a certain strength and size. It is one of the core processes in the production of building ceramics, daily-use ceramics and industrial ceramics.

[0003] Existing ceramic dry pressing equipment is mostly a single-station structure, with the processes of material feeding, pressing, and demolding completed sequentially at the same station. This results in a long production cycle for a single blank, low overall efficiency, and difficulty in meeting the needs of large-scale continuous production. Furthermore, each station is controlled by an independent drive component, which increases the equipment manufacturing cost. Secondly, some multi-station dry pressing equipment uses a rotary table layout, and the indexing of the rotary table is mostly achieved by using a common motor with a reduction gear mechanism. This results in limited positioning accuracy, and misalignment between the mold and the pressing components can easily occur, leading to unstable blank forming quality. Summary of the Invention

[0016] 1. This invention sets up four workstations for cyclical operation: material feeding, pre-pressing, pressing, and demolding. Each workstation can perform its corresponding process simultaneously, which greatly shortens the production cycle of a single blank and realizes continuous dry pressing of ceramic blanks, effectively improving production efficiency. It is suitable for large-scale ceramic production. The first servo motor drives the pre-pressing mechanism and the demolding mechanism simultaneously, so that the pre-pressing plate presses down while the T-shaped block rises to complete the demolding. The actions of the two workstations are completely synchronized. This design reduces the number of driving components and lowers the equipment manufacturing cost.

[0017] 2. The present invention uses a spring buffer structure in the pre-pressing mechanism. During the pressing process of the lifting plate, the pressure is transmitted to the base plate and the pre-pressing plate through the spring. The elastic deformation of the spring is used to achieve flexible pressure, which can adaptively buffer the impact force of the pressing and avoid the problem of powder splashing caused by rigid pressing. At the same time, the powder is more evenly stressed, and the density of the blank after pre-pressing is more consistent, which provides a good foundation for subsequent final pressing molding.

[0018] 3. The present invention, through the setting of the rotating mechanism, drives the turntable to rotate intermittently with the active conjugate cam, which has high indexing accuracy and stable operation. The turntable accurately rotates through one station angle for each rotation of the active conjugate cam. With the conical positioning pin at the top of the mold and the conical positioning hole of the pressing component, the indexing error can be further compensated, ensuring the coaxiality of the mold, the pre-pressing plate and the pressing plate, and significantly improving the molding dimension accuracy.

[0028] 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.

[0029] This invention discloses an adaptive multi-station ceramic dry pressing molding equipment.

[0030] Example 1

[0031] Reference Figure 1-6 This is the first embodiment of the present invention, which provides an adaptive multi-station ceramic dry pressing molding equipment. This adaptive multi-station ceramic dry pressing molding equipment includes a frame 1. The frame 1 adopts a three-layer frame structure, consisting of a top plate, a middle horizontal plate, and a bottom plate, which provides stable installation support for each functional component. A turntable 2 is rotatably connected to the top of the middle horizontal plate of the frame 1. Several molds 3 are fixedly connected to the top of the turntable 2. The molds 3 are arranged symmetrically in pairs in a cross shape, corresponding to four processing stations. The frame 1 is arranged sequentially along the rotation direction of the turntable 2, including a material feeding station, a pre-pressing station, a pressing station, and a demolding station. The four stations are arranged at 90° intervals along the circumference. The turntable 2 can complete one station switch by rotating 90° every time. The frame 1 includes a pre-pressing mechanism 4 and a demolding mechanism 5. The pre-pressing mechanism 4 and the demolding mechanism 5 are arranged opposite to each other. The pre-pressing mechanism 4 corresponds to the pre-pressing station, and the demolding mechanism 5 corresponds to the demolding station. The two are arranged opposite to each other and can complete the pre-pressing and demolding processes simultaneously.

[0032] The top plate of the frame 1 has a first strip groove 41 and a second strip groove 42. A first servo motor 43 is provided on one side of the first strip groove 41. The output shaft of the first servo motor 43 is fixedly sleeved with a first rotating shaft 44. One end of the first rotating shaft 44 is rotatably connected to the inner wall of the second strip groove 42 and fixedly sleeved with a first gear 45. A first toothed plate 46 is meshed on the surface of the first gear 45. A first guide rod 48 is fixedly connected to the top of the first toothed plate 46 through a first connecting block 47. The bottom ends of the first toothed plate 46 and the first guide rod 48 are fixedly connected to the same lifting mechanism. Plate 49, first guide rod 48 slides through the top plate of frame 1 to provide linear guidance for the lifting and lowering movement of first toothed plate 46. Both sides of lifting plate 49 are provided with slide rods 410. The bottom ends of the two slide rods 410 are fixedly connected to the same base plate 411. The bottom end of base plate 411 is integrally formed with a pre-pressing plate 412. The pre-pressing plate 412 is embedded in the inner wall of mold 3. The pre-pressing plate 412 is located directly above mold 3 in the pre-pressing station. Spring 413 is sleeved on the surface of slide rod 410. The two ends of spring 413 are respectively connected to the bottom end of lifting plate 49 and the top end of base plate 411.

[0033] During use, when the first servo motor 43 drives the first gear 45 to rotate, the first toothed plate 46 drives the lifting plate 49 to move downward. The lifting plate 49 pushes the base plate 411 and the pre-pressing plate 412 to press down synchronously through the spring 413. After the pre-pressing plate 412 contacts the powder, the spring 413 generates elastic compression with the downward stroke, buffering the rigid impact force, realizing flexible pre-pressing, avoiding powder splashing and ensuring that the powder is subjected to uniform force.

[0034] Example 2

[0035] Reference Figure 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0036] A through slot 59 is provided on the side of the middle horizontal plate of the frame 1 near the T-shaped block 58. The first rotating shaft 44 is connected to the second rotating shaft 52 through a sprocket drive assembly 51. The sprocket drive assembly 51 is located inside the first slot 41 and consists of two sprockets and a drive chain. The two sprockets are respectively fixedly sleeved on the shaft ends of the first rotating shaft 44 and the second rotating shaft 52. The drive chain is meshed and sleeved on the outside of the two sprockets to achieve synchronous and co-directional rotation of the first rotating shaft 44 and the second rotating shaft 52. One end of the second rotating shaft 52 is rotatably connected to the inner wall of the second slot 42 and fixedly sleeved with a second gear 53. A second toothed plate 54 is meshed and installed on the surface of the second gear 53. Since the second toothed plate 54 and the first toothed plate 46 are respectively arranged on corresponding... Since the gears are on opposite sides, when the two shafts rotate in the same direction, the first gear plate 46 moves downward while the second gear plate 54 moves upward, achieving synchronous action of pre-pressing down and demolding up. The top of the second gear plate 54 is fixedly connected to the second guide rod 56 through the second connecting block 55. The bottom ends of the second gear plate 54 and the second guide rod 56 are fixedly connected to the same lifting frame 57. The second guide rod 56 slides through the top plate of the frame 1 to provide guidance for the lifting of the second gear plate 54. The lifting frame 57 is slidably connected to the middle horizontal plate of the frame 1. The vertical rods on both sides of the lifting frame 57 slide through the middle horizontal plate of the frame 1. The top of the bottom plate of the lifting frame 57 is fixedly connected to a T-shaped block 58, which is located inside the through groove 59 and is located at the demolding station.

[0037] The turntable 2 has several grooves 21 inside, which are located directly below the mold 3. The inner wall of the groove 21 is slidably connected to a force plate 510. One of the force plates 510 is located directly above the T-shaped block 58. A connecting rod 511 is fixedly connected to the top of the force plate 510. The top of the connecting rod 511 passes through the bottom of the mold 3 and is fixedly connected to a demolding template 512. The demolding template 512 is slidably connected to the inner wall of the mold 3.

[0038] During use, when the mold 3 rotates with the turntable 2 to the demolding station, the force plate 510 below it is exactly above the T-shaped block 58. When the second toothed plate 54 drives the lifting frame 57 to rise, the T-shaped block 58 pushes the force plate 510 upward, and then pushes the demolding plate 512 to slide upward along the inner wall of the mold 3 through the connecting rod 511, so as to smoothly eject the formed ceramic blank from the mold 3 and complete the demolding process.

[0039] Example 3

[0040] Reference Figure 1-6 This is the third embodiment of the present invention, which differs from the first embodiment in that:

[0041] The frame 1 also includes a rotating mechanism 6, which drives the turntable 2 to rotate intermittently. A second rotating column 64 is fixedly sleeved inside the turntable 2. A second servo motor 61 is fixedly installed on one side of the base plate of the frame 1. A first rotating column 62 is fixedly sleeved on the output shaft of the second servo motor 61. The top of the first rotating column 62 is rotatably connected to the bottom end of the middle horizontal plate of the frame 1. An active conjugate cam 63 is fixedly sleeved on the surface of the first rotating column 62.

[0042] The bottom end of the second rotating column 64 passes through the middle horizontal plate of the frame 1 and is rotatably connected to the top of the base plate of the frame 1. A driven indexing plate 65 is fixedly sleeved on the surface of the second rotating column 64. Multiple sets of transmission rollers 66 are evenly embedded on the end face of the driven indexing plate 65. The conjugate surface of the active conjugate cam 63 meshes with the transmission rollers 66 to form a parallel conjugate cam indexing structure. When the active conjugate cam 63 rotates one revolution, it drives the driven indexing plate 65 and the turntable 2 to rotate through one work position angle.

[0043] Conical positioning pins 67 are provided at the four corners of the top of the mold 3, and conical positioning holes 68 are provided at the four corners of the bottom of the base plate 411 and the four corners of the bottom of the pressing plate 71. The surface of the conical positioning pins 67 is fitted into the inner wall of the conical positioning holes 68.

[0044] During use, the second servo motor 61 drives the active conjugate cam 63 to rotate at a constant speed for one revolution, which in turn drives the driven indexing plate 65 to rotate precisely 90°. Then, through the second rotating column 64, the turntable 2 and the four molds 3 rotate synchronously through one station angle, realizing precise intermittent switching of the station. The indexing accuracy is high and the running impact is small. When the pre-pressing plate 412 or the pressing plate 71 presses down close to the mold 3, the conical positioning pin 67 first embeds into the conical positioning hole 68. Through the guiding effect of the conical surface, the alignment deviation is automatically corrected, further ensuring the coaxiality of the pre-pressing plate 412, the pressing plate 71 and the mold 3 cavity, and improving the dimensional accuracy of the blank forming.

[0045] Example 4

[0046] Reference Figure 1-6 This is the third embodiment of the present invention, which differs from the first embodiment in that:

[0047] A hydraulic cylinder 7 is fixedly installed on the other side of the top plate of the frame 1. A pressing plate 71 is fixedly connected to the bottom end of the telescopic shaft of the hydraulic cylinder 7. The pressing plate 71 is located directly above the mold 3 on the pressing station. The outer dimensions of the pressing plate 71 are adapted to the cavity of the mold 3. It is set directly opposite the mold 3 on the pressing station. The pressing plate 71 can be pushed down to press the pre-pressed powder for final pressing and forming, so that the blank reaches the set density and strength. Secondly, two symmetrical auxiliary rods can be set above the pressing plate 71, so that the top of the auxiliary rods passes through the top plate of the frame 1 to ensure that the lifting trajectory of the pressing plate 71 will not deviate.

[0048] A controller 8 is provided on one side of the frame 1. The controller 8 is electrically connected to the first servo motor 43, the second servo motor 61 and the hydraulic cylinder 7 respectively. It can control the action sequence of each component according to the preset program to realize the fully automated operation of the equipment.

[0049] The remaining structure is the same as that in Example 1.

[0050] Working principle:

[0051] In the initial state, the four molds 3 correspond to the four workstations respectively. First, a certain amount of ceramic powder is filled into the mold 3 at the material feeding workstation. Then, the controller 8 controls the second servo motor 61 to start, and drives the driven indexing plate 65 and the turntable 2 to rotate 90° through the active conjugate cam 63, completing the first workstation switch. After being loaded, the mold 3 rotates to the pre-pressing workstation, and the empty mold 3 rotates to the material feeding workstation to continue feeding.

[0052] After mold 3 reaches the pre-pressing station, the first servo motor 43 starts and drives the first rotating shaft 44 to rotate. On the one hand, the first gear 45 and the first toothed plate 46 mesh to drive the lifting plate 49 to descend. The lifting plate 49 pushes the base plate 411 and the pre-pressing plate 412 downward through the spring 413. The pre-pressing plate 412 enters the cavity of mold 3 to perform flexible pre-pressing on the powder. The spring 413 buffers the impact force of the downward press, making the powder uniform and dense. On the other hand, the first rotating shaft 44 drives the second rotating shaft 52 to rotate synchronously through the sprocket transmission assembly 51. The second gear 53 meshes with the second toothed plate 54 to drive the lifting frame 57 to rise. The T-shaped block 58 pushes the force plate 510 at the demolding station upward, so that the demolding plate 512 rises and pushes the blank formed in the previous process out of mold 3. The pre-pressing and demolding actions are completed synchronously.

[0053] After pre-pressing and demolding are completed, the first servo motor 43 reverses, driving the pre-pressing plate 412 to rise and reset, and the demolding plate 512 to fall and reset; then the turntable 2 rotates 90° again, the pre-pressed mold 3 rotates to the pressing station, and the demolded empty mold 3 rotates to the material feeding station; the hydraulic cylinder 7 at the pressing station is activated, pushing the pressing plate 71 down to press the powder under high pressure, so that the blank is completely densely formed; at the same time, the pre-pressing station and the material feeding station execute the corresponding processes synchronously.

[0054] After the final pressing is completed, the hydraulic cylinder 7 drives the pressing plate 71 to reset, the turntable 2 rotates 90° again, and the formed blank rotates with the mold 3 to the demolding station, and completes the ejection and demolding in the next cycle; in this way, the cycle repeats, the four stations work continuously and synchronously, and the ceramic blanks can be produced stably and sustainably.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
