Description

Technical Field

[0001] The present invention relates to the technical field of ceramic rod processing equipment, and in particular to an isostatic pressing processing equipment during the forming process of ceramic rods. Background Art

[0002] In the precision forming process system of ceramic rods, isostatic pressing, as 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 that after sealing ceramic powder inside an elastic mold, it is placed inside an isostatic pressing forming machine body, and an isotropic static pressure is applied to the elastic mold through a pressurizing system, so as to compress the voids between powder particles and reduce the molecular spacing, thereby forming a billet with a uniform structure and preparing to obtain a ceramic rod.

[0003] In the prior art, ceramic powder is usually manually loaded into an elastic mold. During this process, the operator needs to repeatedly pour the powder, which is extremely likely to cause the powder to spill from the edge of the elastic mold, resulting in material waste. At the same time, the filling speed of manual operation is slow and the efficiency is low. At the same time, to ensure that the ceramic powder is uniformly compacted in the mold, the traditional method needs to be vibrated and compacted by manually using a hammer to strike the mold. This operation not only consumes a lot of manpower, but also the vibration compaction effect is significantly affected by the experience of the worker, and it is easy to have problems of uneven local compactness. In addition, frequent hammering operations may damage the elastic mold, shorten the service life of the mold, and increase production costs. Therefore, it is necessary to provide an isostatic pressing processing equipment during the forming process of ceramic rods to solve the above technical problems. Summary of the Invention

[0015] Compared with the related art, an isostatic pressing processing device in the process of forming a ceramic rod provided by the present invention has the following beneficial effects:

[0016] 1. The alternating unit drives the driving column through the vertical electric cylinder, so that it moves along the lower vertical guide groove, spiral guide groove, and upper vertical guide groove of the guide groove assembly on the side wall of the rotating cylinder, driving the rotating cylinder to intermittently rotate 180°, realizing the station switching of the two mold placing components. When blanking and vibrating the elastic mold on one side of the mold placing component, the elastic mold that has been filled on the other side can be synchronously removed and put into the isostatic pressing forming machine body for forming processing, shortening the waiting time of the process.

[0017] 2. In the compaction unit, the vibrator is installed below the circular plate. Through the cooperation of the bump 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, allowing the tray to vibrate slightly, replacing the traditional manual hammering compaction method. This can not only reduce the labor intensity of workers and improve the compaction efficiency but also avoid damage to the elastic mold caused by rigid vibration through the elastic structure. Moreover, by driving the upward movement of the driving frame, the fixed ring drives the circular plate to move upward. The circular plate pushes the positioning sleeve to move the tray above the vertical sliding rod. At this time, the third spring is elastically stretched, and the tray is completely separated from the vertical sliding rod. As the tray moves upward, it drives the elastic mold to move upward synchronously, so that the top of the elastic mold approaches the bottom end of the discharge pipe, further reducing the risk of ceramic powder spilling.

[0018] 3. The feeding unit cooperates with the storage tank, the discharge pipe, and the quantitative discharging component. By using the horizontal electric cylinder to drive the upper sealing valve plate and the lower sealing valve plate, the quantitative filling and release of ceramic powder in the discharge pipe are realized. Compared with the traditional manual feeding, it can avoid the spilling of ceramic powder from the edge of the elastic mold, reduce material waste. At the same time, by using the fixed volume of the discharge pipe and the precise movement of the upper sealing valve plate and the lower sealing valve plate, it ensures that the amount of powder falling into the elastic mold is the same each time, improves the filling accuracy, and increases the efficiency of adding ceramic powder into the elastic mold.

[0019] 4. When the vertical electric cylinder drives the driving frame to move up and down, it synchronously drives the fixed ring of the compaction unit and the driving column of the alternating unit to achieve coherent actions. The avoidance through holes on the rotating plate ensure that when the rotating cylinder rotates, the fixed ring can pass smoothly without interfering with the switching of the mold placement component. During the entire processing process, the coordinated cooperation of the support box, the bracket, the alternating unit, the compaction unit, and the feeding unit improves the production efficiency of ceramic rod forming and reduces the manual labor intensity.

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

[0034] Embodiment 1

[0035] Please refer to Figures 1 to 8, an isostatic pressing processing device in the process of forming a ceramic rod, including a support box 1, an elastic mold 6 and an isostatic pressing machine body 7.

One end of the first spring 315 is fixedly connected to the side wall of the driving frame 312, and the other end of the first spring 315 is fixedly connected to one end of the driving column 314.

[0037] In the above, in the driving component 31, the telescopic movement of the vertical electric cylinder 311 drives the driving frame 312 to move up and down. The driving frame 312 is connected to the driving column 314 through the horizontal sliding rod 313, and the first spring 315 keeps applying elastic pressure to the driving column 314.

[0038] The alternating rotation component 32 includes a rotating cylinder 321, the rotating cylinder 321 is rotatably connected to the support box 1, the top end of the rotating cylinder 321 is fixedly connected to a rotating plate 322, and two groups of guide groove components are arranged on the side wall of the rotating cylinder 321. The guide groove components include a lower vertical guide groove 323, a spiral guide groove 324 and an upper vertical guide groove 325. The top end of the lower vertical guide groove 323 is communicated with the bottom end of the upper vertical guide groove 325, the top end of the spiral guide groove 324 is communicated with the bottom end of the upper vertical guide groove 325, a first convex part 3231 is arranged at the top end of the lower vertical guide groove 323, and a second convex part 3241 is arranged at the bottom end of the spiral guide groove 324. The bottom end of the spiral guide groove 324 in one group of guide groove components is communicated with the bottom end of the lower vertical guide groove 323 in the other group of guide groove components. The guide grooves in the two groups of guide groove components are just arranged in a circle outside the rotating cylinder 321, and the driving column 314 extends into the inner bottom end of the lower vertical guide groove 323.

[0039] In the above, the two groups of guide groove assemblies on the side wall of the rotating drum 321, 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 an annular path. When the driving column 314 moves along the guide groove, the spiral trajectory of the spiral guide groove 324 forces the rotating drum 321 to rotate, and the first protrusion 3231 and the second protrusion 3241 limit the movement direction of the driving column 314 to ensure that the rotating drum 321 only rotates in one direction.

[0040] The mold placement component 33 includes a tray 331 . The tray 331 is arranged on one side above the rotating plate 322 . Two mold placement sleeves 332 are symmetrically 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 adapted to the outer diameter of the elastic mold 6. The mold is fixed by interference fit. When the rotating drum 321 rotates 180°, the two sets of trays 331 are respectively switched to the bottom of the unloading unit 5 and the side of the isostatic pressing machine body 7 to achieve automatic switching.

[0042] Embodiment 2

[0043] See also Figures 1 to 10 On the basis of the first embodiment, the vibration unit 4 includes a vibration component 41 and a receiving component 42, the vibration component 41 is arranged on the driving component 31, and the receiving component 42 is arranged on the alternating rotating component 32; the vibration component 41 includes a fixing ring 411, the fixing ring 411 is fixedly connected to the other end of the driving frame 312, a circular plate 412 is arranged on the inner side of the fixing ring 411, and 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, and a second spring 415 is arranged 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 at the lower part of the circular plate 412.

[0044] In the above, the vibrator 416 generates high-frequency vibration after being energized, which is transmitted to the protrusion 414 through the circular plate 412. The rubber block 413 and the second spring 415 constitute an elastic buffer structure, allowing the circular plate 412 to swing slightly in the fixing ring 411 to avoid damage to the mold due to rigid vibration. When the driving frame 312 moves upward to insert the protrusion 414 into the positioning sleeve 421, the vibration is transmitted to the tray 331 through the positioning sleeve 421, so that the ceramic powder in the elastic mold 6 is vibrated.

[0045] Two receiving parts 42 are symmetrically arranged and are arranged one by one corresponding to the mold placing parts 33. The receiving part 42 includes a positioning sleeve 421, which is fixedly connected to the bottom of the tray 331. The positioning sleeve 421 is arranged just above the protrusion 414 and is adapted thereto. A plurality of vertical sliding rods 422 are arranged in a circular array on the tray 331. The sliding sleeve longitudinally penetrates the tray 331 and is arranged on the outer side of the vertical sliding rod 422. The bottom end of the vertical sliding rod 422 is fixedly connected to the top of the driving frame 312. The outer side of the vertical sliding rod 422 is sleeved with a third spring 423. 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 driving frame 312. Two avoidance through holes 424 for avoiding the fixing ring 411 are symmetrically and longitudinally penetrated on the rotating plate 322.

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

[0047] Embodiment 3

[0048] See also Figures 1 to 12 On the basis of the second embodiment, the unloading unit 5 includes a unloading component 51 and a quantitative discharging component 52. The unloading component 51 is arranged on the bracket 2, and the quantitative discharging component 52 is arranged on the unloading component 51; the unloading component 51 includes a storage tank 511, and the storage tank 511 is fixedly connected to the bracket 2. The bottom end of the storage tank 511 is connected to two symmetrically arranged discharging pipes 512. The upper part of the discharging pipe 512 is penetrated and fixedly connected with an upper horizontal sliding sleeve 513, and the lower part of the discharging pipe 512 is penetrated and fixedly connected with 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 wall to ensure the smooth falling of the ceramic powder. The upper horizontal sliding sleeve 513 and the lower horizontal sliding sleeve 514 are respectively located at the upper and lower parts of the discharge pipe 512, forming an upper and lower sliding track, which are respectively used to install the upper sealing valve plate 525 and the lower sealing valve plate 523.

[0050] The quantitative discharging component 52 includes a horizontal electric cylinder 521, the horizontal electric cylinder 521 is fixedly connected to the bracket 2, a pushing frame 522 is fixedly connected to the telescopic end of the horizontal electric cylinder 521, an upper plug valve plate 525 is horizontally and slidably connected through the inner side of the upper horizontal sliding sleeve 513, a lower plug valve plate 523 is horizontally and slidably connected through the inner side of the lower horizontal sliding sleeve 514, a feed port 526 is longitudinally formed through the upper plug valve plate 525, a discharge port 524 is longitudinally formed through the lower plug valve plate 523, and one ends of the lower plug valve plate 523 and the upper plug valve plate 525 are fixedly connected to the side wall of the pushing frame 522.

[0051] Among the above, the horizontal electric cylinder 521 drives the pushing frame 522 to move horizontally. In the initial state, the feed port 526 of the upper plug 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 contracts, the upper plug valve plate 525 closes the feed port 526. At the same time, the discharge port 524 of the lower plug valve plate 523 is aligned with the discharge pipe 512, and a quantitative 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, quantitative feeding can be achieved.

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

[0053] The working principle of an isostatic pressing processing device during the forming process of a ceramic rod provided by the present invention is as follows:

[0054] During use, the ceramic powder for making the ceramic rod is placed in the storage tank 511 for storage. An elastic mold 6 is placed in each of the mold placing sleeves 332 directly below the 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 to drive the driving frame 312 to move upward synchronously. The driving frame 312 drives the horizontal slide bar 313 to move the driving column 314 upward. While the driving frame 312 moves upward, it also drives the fixed ring 411 to move upward synchronously.

[0055] Due to the settings of the first protrusion 3231 and the second protrusion 3241, the depths in the lower vertical guide groove 323, the spiral guide groove 324, and the upper vertical guide groove 325 are not consistent. Therefore, the driving column 314 needs to have a certain lateral movement range. The transverse sliding rod 313 is slidably matched with the driving frame 312. Thus, the transverse sliding rod 313 can slide within a small range on the driving frame 312. The first spring 315 in the compressed state will keep pressing on the driving column 314, so that the end of the driving column 314 can be kept within the corresponding lower vertical guide groove 323, spiral guide groove 324, and upper vertical guide groove 325. First, the driving 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 driving column 314 moves upward along the upper vertical guide groove 325, the fixing ring 411 enters the avoidance through hole 424. Subsequently, the convex block 414 is inserted into the positioning sleeve 421. As the driving 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 sliding rod 422. At this time, the third spring 423 is elastically stretched, and the tray 331 is completely separated from the vertical sliding 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 end of the discharge pipe 512, and a part of the bottom end of the discharge pipe 512 extends into the elastic mold 6.

[0056] Start the vibrator 416 and the horizontal electric cylinder 521. The telescopic end of the horizontal electric cylinder 521 contracts to drive the pushing frame 522 to move horizontally. The pushing 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 downward into the horizontal sliding sleeve 514, and at the same time causing the upper sealing valve plate 525 to move upward into the horizontal sliding sleeve 513. Initially, the feed port 526 corresponds to the discharge pipe 512, while the discharge port 524 is in a staggered state with the discharge pipe 512. The ceramic powder in the storage tank 511 falls into the discharge pipe 512 under the action of its own gravity and fills the inside of the discharge pipe 512. As the telescopic end of the horizontal electric cylinder 521 contracts, the movement of the upper sealing valve plate 525 causes the feed port 526 to be staggered from the discharge pipe 512. At this time, the upper sealing valve plate 525 seals the top of the discharge pipe 512, and the ceramic powder in the storage tank 511 is blocked above the upper sealing valve plate 525. The horizontal electric cylinder 521 continues to drive the lower sealing valve plate 523 to move downward into the horizontal sliding sleeve 514 until the discharge port 524 is directly corresponding to the discharge pipe 512. At this time, the ceramic powder in the discharge pipe 512 falls into the corresponding elastic mold 6 under the action of its own gravity, realizing the quantitative addition of ceramic powder into the elastic mold 6. And during this process, the vibrator 416 works to generate vibration. The vibration force is transmitted to the elastic mold 6 through the circular plate 412, the fixed 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 enable the tray 331 to swing within a small range during vibration, improving the compaction effect, so that there is no need for manual hammering to make the ceramic powder inside the elastic mold 6 reach the compaction effect.

[0057] When the ceramic powder in the elastic mold 6 is added, then control the telescopic end of the horizontal electric cylinder 521 to extend, so that the lower sealing valve plate 523 and the upper sealing valve plate 525 are reset. The lower sealing valve plate 523 seals the lower part of the discharge pipe 512, and 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 into the elastic mold 6.

[0058] Subsequently, the telescopic end of the vertical electric cylinder 311 contracts, causing the driving frame 312 to move downward. The driving frame 312 drives the fixed ring 411 to move downward, and the fixed ring 411 drives the circular plate 412 and the convex block 414 to move downward. As the circular plate 412 moves downward, the elastic potential energy of the third spring 423 is gradually released until the tray 331 is sleeved on the vertical sliding rod 422 again. When the driving column 314 moves downward and enters the bottom end of the upper vertical guiding groove 325, at this time, the convex block 414 also moves below the driving frame 312, so that the vibrating component 41 will not interfere with the rotation of the driving frame 312. Subsequently, the telescopic end of the vertical electric cylinder 311 continues to contract, and the driving column 314 enters the spiral guiding groove 324 from the bottom end of the upper vertical guiding groove 325. Under the guiding action of the spiral guiding groove 324, the driving column 314 moves from the top end of the spiral guiding groove 324 to the bottom end of the spiral guiding groove 324, causing the rotating cylinder 321 to rotate 180°. By providing the second protrusion 3241, after the driving column 314 enters the lower vertical guiding groove 323 from the bottom end of the spiral guiding groove 324, when the driving column 314 moves upward, it can only move along the lower vertical guiding groove 323 and will not return to the spiral guiding groove 324. Through the provision of the first protrusion 3231, after the driving column 314 enters the upper vertical guiding groove 325 from the top end of the lower vertical guiding groove 323, when the driving column 314 moves downward, it can only enter the spiral guiding groove 324 and will not return to the lower vertical guiding groove 323 again, so that the rotating cylinder 321 always rotates in one direction.

[0059] By switching the mold placing component 33 with another new elastic mold 6 placed thereon to the lower material unit 5, adding ceramic powder in the above-mentioned manner, and then switching the mold placing component 33 with the added ceramic powder to one side, it is convenient to remove the elastic mold 6 with the added ceramic powder and seal it. Then, the elastic mold 6 is placed into the isostatic pressing machine body 7, and the isostatic pressing machine body 7 is started for forming operation. Subsequently, a new elastic mold 6 is placed in the mold placing sleeve 332 of the vacant mold placing component 33 to prepare for the next feeding.
