Description

Technical Field

[0001] This invention relates to the technical field of ceramic rod processing equipment, and more particularly to an isostatic pressing processing equipment for ceramic rod forming process. Background Technology

[0002] In the precision forming process of ceramic rods, isostatic pressing is the core process. Its technical implementation path directly determines the density, mechanical properties and dimensional accuracy of the final product. The core principle of this process is to seal ceramic powder inside an elastic mold and place it in the body of an isostatic pressing machine. The pressurization system applies uniform static pressure to the elastic mold in all directions, which causes the gaps between powder particles to be compressed and the intermolecular distance to be reduced, thereby forming a uniformly structured green body and preparing ceramic rods.

[0003] In existing technologies, ceramic powder is typically manually loaded into an elastic mold. This process requires repeated pouring of powder, which easily leads to powder spillage from the mold's edges, resulting in material waste. Furthermore, manual filling is slow and inefficient. To ensure uniform compaction of the ceramic powder within the mold, traditional methods require manual hammering. This is not only labor-intensive but also highly dependent on worker experience, easily leading to uneven compaction in certain areas. Moreover, frequent hammering can damage the elastic mold, shortening its lifespan and increasing production costs. Therefore, it is necessary to provide an isostatic pressing (OSP) processing device for ceramic rod forming to solve these technical problems. Summary of the Invention

[0011] Preferably, two receiving components are symmetrically arranged and correspond one-to-one with the mold placement components. Each receiving component includes a positioning sleeve, which is fixedly connected to the bottom of the tray and positioned directly above and adapted to the protrusion. Several vertical sliding rods are arranged in a circumferential array on the tray. The tray is longitudinally slidably sleeved on the outside of the vertical sliding rods.

[0012] Preferably, the feeding unit includes a feeding component and a quantitative discharging component, wherein the feeding component is mounted on a support and the quantitative discharging component is mounted on the feeding component.

[0013] Preferably, the feeding component includes a storage tank, which is fixedly connected to the support.

An upper horizontal sliding sleeve is fixedly connected through the upper part of the discharge pipe, and a lower horizontal sliding sleeve is fixedly connected through the lower part of the discharge pipe.

[0014] Preferably, the quantitative discharge component includes a horizontal electric cylinder, which is fixedly connected to the bracket.

One end of both the lower and upper sealing valve plates is fixedly connected to the side wall of the push frame. When the discharge outlet is directly opposite the discharge pipe, the feed inlet and the discharge pipe are in a staggered state.

[0015] Compared with related technologies, the isostatic pressing processing equipment for ceramic rod forming provided by the present invention has the following beneficial effects:

[0016] 1. The alternating unit drives the drive column through a vertical electric cylinder, causing it to move along the guide groove assembly on the side wall of the rotating drum, including the lower vertical guide groove, the spiral guide groove, and the upper vertical guide groove. This causes the rotating drum to rotate intermittently by 180°, enabling the switching of the workstations of the two mold placement components. This allows the elastic mold on one side of the mold placement component to be unloaded and vibrated, while the elastic mold on the other side, which has already been filled, is simultaneously removed and placed into the isostatic pressing machine body for molding processing, thus shortening the waiting time for the process.

[0017] 2. In the vibration compaction unit, the vibrator is installed below the circular plate. Through the cooperation of the protrusion and the positioning sleeve, the vibration is transmitted to the tray and the elastic mold. The rubber block, the second spring, and the third spring constitute an elastic buffer system, which allows the tray to vibrate slightly. This replaces the traditional manual hammering compaction method, which can reduce the labor intensity of workers, improve compaction efficiency, and avoid damage to the elastic mold caused by rigid vibration through the elastic structure. Furthermore, the upward movement of the drive frame causes the fixed ring to drive the circular plate to move upward. The circular plate pushes the positioning sleeve to move the tray above the vertical slide bar. At this time, the third spring is elastically stretched, and the tray is completely separated from the vertical slide bar. As the tray moves upward, it drives the elastic mold to move upward synchronously, so that the top of the elastic mold is close to the bottom of the discharge pipe, which further reduces the risk of ceramic powder spillage.

[0018] 3. The feeding unit works in conjunction with the storage tank, the discharge pipe and the quantitative discharge component. The upper and lower sealing valve plates are driven by a horizontal electric cylinder to achieve quantitative filling and release of ceramic powder in the discharge pipe. Compared with traditional manual feeding, it can prevent ceramic powder from spilling from the edge of the elastic mold, reducing material waste. At the same time, the fixed volume of the discharge pipe and the precise movement of the upper and lower sealing valve plates ensure that the amount of powder falling into the elastic mold is consistent each time, improving the filling accuracy and increasing the efficiency of adding ceramic powder into the elastic mold.

[0019] 4. When the vertical electric cylinder drives the drive frame to move up and down, it simultaneously drives the fixed ring of the vibration unit and the drive column of the alternating unit to achieve continuous action. The clearance through hole on the rotating plate ensures that the fixed ring can pass smoothly without interfering with the switching of the mold placement parts when the rotating cylinder rotates. In the entire processing process, the coordinated cooperation of the support box, bracket, alternating unit, vibration unit and feeding unit improves the production efficiency of ceramic rod forming and reduces the intensity of manual labor.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] Please refer to the following: Figures 1 to 8An isostatic pressing processing device for ceramic rod forming includes a support box 1, an elastic mold 6, and an isostatic pressing machine body 7. A bracket 2 is fixedly connected to the top of the support box 1. An alternating unit 3 is provided on the top of the support box 1, and a vibration unit 4 is provided on the alternating unit 3. A feeding unit 5 is provided on the bracket 2. The alternating unit 3 includes a driving component 31, an alternating rotating component 32, and a mold placement component 33. The mold placement component 33 is located on the alternating rotating component 32 and two are symmetrically arranged. The driving component 31 is used to drive the alternating rotating component 32 to rotate intermittently by 180° to realize the alternating switching of the two mold placement components 33.

[0036] The drive component 31 includes a vertical electric cylinder 311, which is fixedly connected to the support box 1. The telescopic end of the vertical electric cylinder 311 is fixedly connected to a drive frame 312. One end of the drive frame 312 is laterally slidably connected to a horizontal slide rod 313. One end of the horizontal slide rod 313 is fixedly connected to a drive column 314. A first spring 315 is sleeved on the outside of the horizontal slide rod 313. One end of the first spring 315 is fixedly connected to the side wall of the drive frame 312, and the other end of the first spring 315 is fixedly connected to one end of the drive column 314.

[0037] In the above, in the drive component 31, the drive frame 312 moves up and down by the extension and retraction of the vertical electric cylinder 311. The drive frame 312 is connected to the drive column 314 through the horizontal slide bar 313. The first spring 315 maintains the application of elastic pressure to the drive column 314.

[0038] The alternating rotating component 32 includes a rotating cylinder 321, which is rotatably connected to the support box 1. A rotating plate 322 is fixedly connected to the top of the rotating cylinder 321. Two sets of guide groove assemblies are provided on the side wall of the rotating cylinder 321. The guide groove assembly includes a lower vertical guide groove 323, a spiral guide groove 324, and an upper vertical guide groove 325. The top of the lower vertical guide groove 323 is connected to the bottom of the upper vertical guide groove 325, and the top of the spiral guide groove 324 is connected to the bottom of the upper vertical guide groove 325. A first protrusion 3231 is provided at the top of the lower vertical guide groove 323, and a second protrusion 3241 is provided at the bottom of the spiral guide groove 324. The bottom of the spiral guide groove 324 in one set of guide groove assemblies is connected to the bottom of the lower vertical guide groove 323 in the other set of guide groove assemblies. The guide grooves in the two sets of guide groove assemblies are located on the outside of the rotating cylinder 321 and form a circle. The drive column 314 extends into the inner bottom of the lower vertical guide groove 323.

[0039] In the above, the two sets of guide groove assemblies on the side wall of the rotating drum 321, namely the lower vertical guide groove 323, the spiral guide groove 324 and the upper vertical guide groove 325, are connected end to end to form a ring path. When the drive column 314 moves along the guide groove, the spiral trajectory of the spiral guide groove 324 forces the rotating drum 321 to rotate. The first protrusion 3231 and the second protrusion 3241 restrict the movement direction of the drive column 314 to ensure that the rotating drum 321 rotates only in one direction.

[0040] The mold placement component 33 includes a tray 331, which is located on one side above the rotating plate 322. Two mold placement sleeves 332 are symmetrically and fixedly connected to the top of the tray 331.

[0041] In the above, the tray 331 is fixed to the rotating plate 322 by bolts, and the mold placement sleeve 332 is a cylindrical structure that is adapted to the outer diameter of the elastic mold 6. The mold is fixed by interference fit. When the rotating cylinder 321 rotates 180°, the two sets of trays 331 are switched to the bottom of the feeding unit 5 and the side of the isostatic pressing machine body 7, respectively, to achieve automatic switching.

[0042] Example 2

[0043] See Figures 1 to 10 Based on Embodiment 1, the vibration unit 4 includes a vibration component 41 and a receiving component 42. The vibration component 41 is disposed on the driving component 31, and the receiving component 42 is disposed on the alternating rotation component 32. The vibration component 41 includes a fixing ring 411, which is fixedly connected to the other end of the driving frame 312. A circular plate 412 is disposed on the inner side of the fixing ring 411. A plurality of rubber blocks 413 are arranged in a circular array on the outer side of the circular plate 412. One end of the rubber block 413 is fixedly connected to the outer side wall of the circular plate 412, and the other end of the rubber block 413 is fixedly connected to the inner side wall of the fixing ring 411. A second spring 415 is disposed between two adjacent rubber blocks 413. One end of the second spring 415 is fixedly connected to the inner side wall of the fixing ring 411, and the other end of the second spring 415 is fixedly connected to the outer side wall of the circular plate 412. A protrusion 414 is fixedly connected to the top of the circular plate 412, and a vibrator 416 is fixedly installed on the lower part of the circular plate 412.

[0044] In the above, the vibrator 416 generates high-frequency vibration after being powered on, which is transmitted to the protrusion 414 through the circular plate 412. The rubber block 413 and the second spring 415 form an elastic buffer structure, allowing the circular plate 412 to swing slightly within the fixed ring 411, avoiding rigid vibration that could damage the mold. When the drive frame 312 moves upward and the protrusion 414 is inserted into the positioning sleeve 421, the vibration is transmitted to the tray 331 through the positioning sleeve 421, causing the ceramic powder in the elastic mold 6 to be compacted.

[0045] Two receiving components 42 are symmetrically arranged and correspond one-to-one with the mold placement components 33. The receiving component 42 includes a positioning sleeve 421, which is fixedly connected to the bottom of the tray 331. The positioning sleeve 421 is located directly above the protrusion 414 and is adapted to it. Several vertical sliding rods 422 are arranged in a circular array on the tray 331. The tray 331 is longitudinally slidably sleeved on the outside of the vertical sliding rods 422. The bottom end of the vertical sliding rod 422 is fixedly connected to the top of the rotating plate 322. A third spring 423 is sleeved on the outside of the vertical sliding rod 422. The top end of the third spring 423 is fixedly connected to the bottom of the tray 331, and the bottom end of the third spring 423 is fixedly connected to the top of the rotating plate 322. Two clearance through holes 424 are symmetrically and longitudinally opened on the rotating plate 322 to avoid the fixing ring 411.

[0046] In the above, the lower end of the positioning sleeve 421 is open, and the inner wall is in clearance fit with the outer surface of the protrusion 414. The surface of the vertical slide rod 422 is smooth and forms a sliding fit with the sliding hole of the tray 331. The third spring 423 is not under force in the initial state. When the tray 331 is lifted, the third spring 423 is stretched to provide a reset pull force, avoiding the through hole 424 whose diameter is larger than the outer diameter of the fixing ring 411.

[0047] Example 3

[0048] See Figures 1 to 12 Based on Embodiment 2, the feeding unit 5 includes a feeding component 51 and a quantitative discharging component 52. The feeding component 51 is mounted on the support 2, and the quantitative discharging component 52 is mounted on the feeding component 51. The feeding component 51 includes a storage tank 511, which is fixedly connected to the support 2. The bottom end of the storage tank 511 is connected to two symmetrically arranged discharge pipes 512. The upper part of the discharge pipe 512 is fixedly connected to an upper horizontal sliding sleeve 513, and the lower part of the discharge pipe 512 is fixedly connected to a lower horizontal sliding sleeve 514.

[0049] In the above, the bottom of the storage tank 511 is conical, and the inner wall of the discharge pipe 512 is a smooth surface to ensure that the ceramic powder falls smoothly. The upper horizontal sliding sleeve 513 and the lower horizontal sliding sleeve 514 are located at the upper and lower parts of the discharge pipe 512, respectively, forming two layers of sliding tracks, which are used to install the upper sealing valve plate 525 and the lower sealing valve plate 523, respectively.

[0050] The quantitative discharge component 52 includes a horizontal electric cylinder 521, which is fixedly connected to the bracket 2. The telescopic end of the horizontal electric cylinder 521 is fixedly connected to a pusher frame 522. The inner side of the upper horizontal sliding sleeve 513 is slidably connected to an upper sealing valve plate 525, and the inner side of the lower horizontal sliding sleeve 514 is slidably connected to a lower sealing valve plate 523. The upper sealing valve plate 525 has a longitudinally penetrating inlet 526, and the lower sealing valve plate 523 has a longitudinally penetrating outlet 524. One end of both the lower sealing valve plate 523 and the upper sealing valve plate 525 is fixedly connected to the side wall of the pusher frame 522. When the outlet 524 is directly opposite the discharge pipe 512, the inlet 526 and the discharge pipe 512 are in a staggered state.

[0051] In the above, the horizontal electric cylinder 521 drives the push frame 522 to move laterally. In the initial state, the feed port 526 of the upper sealing valve plate 525 is aligned with the discharge pipe 512, and the ceramic powder fills the discharge pipe 512. When the horizontal electric cylinder 521 retracts, the upper sealing valve plate 525 closes the feed port 526, and at the same time, the discharge port 524 of the lower sealing valve plate 523 is aligned with the discharge pipe 512. A fixed amount of powder falls into the elastic mold 6 below it. Since the amount of ceramic powder filled in the discharge pipe 512 is basically the same, a fixed amount of material can be dispensed.

[0052] The vertical electric cylinder 311, vibrator 416, horizontal electric cylinder 521, and isostatic pressing machine body 7 are all electrically connected to an external control switch via wires.

[0053] The working principle of the isostatic pressing processing equipment in the ceramic rod forming process provided by this invention is as follows:

[0054] In use, ceramic powder for making ceramic rods is placed into storage tank 511 for storage. An elastic mold 6 is placed in mold placement sleeve 332 located directly below discharge pipe 512. The top of the elastic mold 6 is opened, and the vertical electric cylinder 311 is started. The telescopic end of the vertical electric cylinder 311 extends upward, driving the drive frame 312 to move upward synchronously. The drive frame 312 drives the horizontal slide bar 313 to move the drive column 314 upward. At the same time, the drive frame 312 moves upward, driving the fixed ring 411 to move upward synchronously.

[0055] Due to the arrangement of the first protrusion 3231 and the second protrusion 3241, the depths of the lower vertical guide groove 323, the spiral guide groove 324, and the upper vertical guide groove 325 are not consistent. Therefore, the drive column 314 needs a certain range of lateral movement. The horizontal slide bar 313 slides in cooperation with the drive frame 312. Thus, the horizontal slide bar 313 can slide within a small range on the drive frame 312. The compressed first spring 315 will keep the drive column 314 pressed, so that the end of the drive column 314 can be kept in the corresponding lower vertical guide groove 323, spiral guide groove 324, and upper vertical guide groove 325. First, the drive column 314 moves upward along the lower vertical guide groove 323 and enters the upper vertical guide groove 325 through the lower vertical guide groove 323. As the drive column 314 moves upward along the upper vertical guide groove 325, the fixing ring 411 enters the clearance through hole 424. Then, the protrusion 414 is inserted into the positioning sleeve 421. As the drive frame 312 moves further upward, the fixing ring 411 drives the circular plate 412 to move upward. The circular plate 412 pushes the positioning sleeve 421 to move the tray 331 above the vertical slide rod 422. At this time, the third spring 423 is elastically stretched, and the tray 331 is completely separated from the vertical slide rod 422. As the tray 331 moves upward, it drives the elastic mold 6 to move upward synchronously, so that the top of the elastic mold 6 corresponds to the bottom of the discharge pipe 512, and the bottom part of the discharge pipe 512 extends into the elastic mold 6.

[0056] The vibrator 416 and the horizontal electric cylinder 521 are started. The retraction end of the horizontal electric cylinder 521 retracts, causing the push frame 522 to move laterally. The push frame 522 drives the lower sealing valve plate 523 and the upper sealing valve plate 525 to move synchronously, causing the lower sealing valve plate 523 to move into the lower horizontal sliding sleeve 514, and at the same time causing the upper sealing valve plate 525 to move into the upper horizontal sliding sleeve 513. Initially, the feed port 526 corresponds to the discharge pipe 512, while the discharge port 524... The discharge pipe 512 is offset from the inlet 511. Under its own weight, the ceramic powder in the storage tank 511 falls into the discharge pipe 512, filling it completely. As the telescopic end of the horizontal electric cylinder 521 retracts, the upper sealing valve plate 525 moves, causing the inlet 526 to be offset from the discharge pipe 512. At this time, the upper sealing valve plate 525 seals the top of the discharge pipe 512, preventing the ceramic powder in the storage tank 511 from being trapped. Above the sealing valve plate 525, the horizontal electric cylinder 521 continues to drive the lower sealing valve plate 523 to move into the lower horizontal sliding sleeve 514 until the discharge port 524 is directly aligned with the discharge pipe 512. At this time, the ceramic powder in the discharge pipe 512 falls into the corresponding elastic mold 6 under its own gravity, realizing the quantitative addition of ceramic powder into the elastic mold 6. During this process, the vibrator 416 works and generates vibration. The vibration force is transmitted to the elastic mold 6 through the circular plate 412, the fixing ring 411, the positioning sleeve 421 and the tray 331, so that the ceramic powder entering the elastic mold 6 is compacted. The rubber block 413, the second spring 415 and the third spring 423 cooperate to allow the tray 331 to swing within a small range during vibration, improving the compaction effect. Thus, it is not necessary to manually use a hammer to compact the ceramic powder inside the elastic mold 6.

[0057] After the ceramic powder is added to the elastic mold 6, the telescopic end of the horizontal electric cylinder 521 is extended to reset the lower sealing valve plate 523 and the upper sealing valve plate 525. The lower sealing valve plate 523 seals the lower part of the discharge pipe 512, while the ceramic powder in the storage tank 511 enters the discharge pipe 512 through the feed port 526, preparing for the next addition of ceramic powder to the elastic mold 6.

[0058] Then, the telescopic end of the vertical electric cylinder 311 retracts, causing the drive frame 312 to move downwards. The drive frame 312 drives the fixed ring 411 to move downwards, and the fixed ring 411 drives the circular plate 412 and the protrusion 414 to move downwards. As the circular plate 412 moves downwards, the elastic potential energy of the third spring 423 is gradually released until the tray 331 is once again fitted onto the vertical slide rod 422. When the drive column 314 moves downwards and enters the bottom end of the upper vertical guide groove 325, the protrusion 414 also moves to the bottom of the drive frame 312. At this time, the vibrating component 41 will not interfere with the rotation of the drive frame 312. Then, the telescopic end of the vertical electric cylinder 311 continues to retract, and the drive column 314 enters the spiral guide groove 324 from the bottom end of the upper vertical guide groove 325. Under the guidance of 4, the drive column 314 moves from the top of the spiral guide groove 324 to the bottom of the spiral guide groove 324, causing the rotating drum 321 to rotate 180°. By setting the second protrusion 3241, after the drive column 314 enters the lower vertical guide groove 323 from the bottom of the spiral guide groove 324, when the drive column 314 moves upward, it can only move along the lower vertical guide groove 323 and will not return to the spiral guide groove 324. By setting the first protrusion 3231, after the drive column 314 enters the upper vertical guide groove 325 from the top of the lower vertical guide groove 323, when the drive column 314 moves downward, it can only enter the spiral guide groove 324 and will not return to the lower vertical guide groove 323, thereby making the rotating drum 321 always rotate in one direction.

[0059] By switching another mold placement component 33 containing a new elastic mold 6 to below the feeding unit 5, ceramic powder is added in the manner described above. The mold placement component 33 with added ceramic powder is then switched to one side, making it easier to remove the elastic mold 6 with added ceramic powder and seal it. The elastic mold 6 is then placed into the isostatic pressing machine body 7, and the isostatic pressing machine body 7 is started for molding. Subsequently, a new elastic mold 6 is placed in the mold placement sleeve 332 of the empty mold placement component 33 to prepare for the next feeding.

[0060] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
