Description

Technical Field

[0001] The invention relates to the technical field of ceramic dry bag isostatic pressing, and more particularly to a rotary distributor for a dry bag isostatic pressing machine. Background Art

[0002] Isostatic pressing (IP) ceramic processing typically uses dry powder as the raw material. The sample to be pressed is placed in a high-pressure vessel. The liquid medium's incompressibility and uniform pressure transmission properties are exploited to uniformly pressurize the sample from all directions. As the liquid medium is pumped into the pressure vessel, its pressure remains constant and evenly transmitted in all directions, according to the principles of fluid mechanics. This results in uniform pressure on the powder in the vessel.

[0003] When using dry bag isostatic pressing to form larger-sized (diameter greater than 160mm) cylinders or tubes such as alumina, zirconia, and silicon carbide, such as the dry bag isostatic pressing of the inner barrel of a sand mill, it is hoped that the formed body will have a small dimensional margin and uniform wall thickness. This not only saves powder, but also saves post-processing costs and reduces production costs. This puts higher demands on online cloth.

[0004] Dry bag isostatic pressing technology typically involves on-machine material placement. To improve production efficiency, this shortens material placement time, but vibration is not permitted, as this can affect equipment accuracy and service life. Severely uneven material placement can also result in an underfill or concave top portion of the blank, impacting the quality rate and increasing production costs.

[0005] Existing dry bag press tube feeding methods mostly use a scraper-type feeding method, with multiple smaller feeding hoses evenly spaced around the periphery. Feeding begins from the periphery toward the center, and begins when the isostatic cylinder descends to a certain distance from the upper pressure head. While this method is simple, the isostatic cylinder cannot be pressurized in place after feeding. The mold core and lower pressure head must be constructed as separate structures. After filling, the lower pressure head descends to leave room for the upper pressure head to enter the mold before it can rise with the isostatic cylinder to begin pressurization. This complex action makes relative position control more difficult, and the increased movement of the lower pressure head after separation can easily lead to wear, powder leakage, and mold jamming. After the isostatic cylinder descends to a certain position, the isostatic cylinder and the upper pressure head are separated by a certain distance. Feeding hoses evenly distributed around the upper pressure head are controlled by valves to begin feeding, and the valves are closed when feeding is completed. Since feeding occurs at the periphery, it is an open-type method, generating significant dust and significantly impacting the working environment. Furthermore, uneven feeding can be caused by a limited number of feeding hoses or the asynchronous opening and closing of individual valves.

[0006] Another way is to place the material in a porous plate inside the upper pressure head. Although it solves the problems of die sticking and dust generation, the powder required to press a cylinder (tens of kilograms or even more, the amount of powder can be controlled by controlling the gate opening time or weighing the material) must be added to the mold in a short time. The diameter of the discharge pipe will not be too small, that is, the gate opening of the gate valve is large, and there is a time difference between the opening and closing when the cylinder drags the gate, that is, the position that opens first is the last to be closed. This results in more material being discharged from the side that opens first and less material being discharged from the side that opens later. Moreover, after the gate is opened, the pressure difference generated by the funnel powder causes the powder to not fall completely vertically, but to pour down toward the opening direction, thereby exacerbating the unevenness of the filler, resulting in uneven wall thickness of the pressed green body, which brings greater workload to subsequent processing.

[0007] Therefore, how to provide a rotary distributor for a dry bag isostatic pressing machine to ensure uniform distribution during the production process, reduce the production cost of ceramic cylinders, and ensure uniform wall thickness and consistent size and shape of the processed blanks is an urgent problem that needs to be solved by technical personnel in this field. Summary of the Invention

[0008] In view of this, the present invention provides a rotary distributor for a dry bag isostatic pressing machine, which is designed for larger-sized cylinders or tubes (greater than 160 mm) such as alumina, zirconia, and silicon carbide. The rotary distributor ensures that the outer dimensions of the formed blanks have a small margin and uniform wall thickness, thus saving powder and processing costs and reducing production costs.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] A rotary distributor for a dry bag isostatic pressing machine, the dry bag isostatic pressing machine having a drive mechanism, comprising:

[0011] blanking plate;

[0012] A guide cone, the large end of which is detachably connected to the blanking plate;

[0013] An annular shell is detachably connected to the circumference of the upper end of the blanking plate, and a powder flow gap is reserved between the inner wall of the annular shell and the outer wall of the guide cone; the powder flow gap corresponds to a plurality of blanking holes spaced apart on the annular belt of the blanking plate;

[0014] an annular outer disk, wherein the lower end annular surface of the annular outer disk is detachably connected to the upper end annular surface of the annular outer shell;

[0015] an annular inner disk, the annular inner disk being sleeved in the annular cavity of the annular outer disk and being rotatably connected to the annular outer disk, the annular cavity of the annular inner disk being in communication with the inner cavity of the annular outer shell; the small end of the guide cone extending into the annular cavity of the annular inner disk;

[0016] Wherein, the annular shell or the annular outer disk is transmission-connected to the driving mechanism of the dry bag isostatic pressing machine.

[0017] Through the above technical solution, when the rotary distributor of the dry bag isostatic pressing machine provided by the present invention is used for distributing materials, the rotary distributor can realize discharging while rotating. During the rotation process, the position of the discharge hole relative to the mold in the dry bag isostatic pressing machine is constantly changing in a cycle. At the same time, under the action of centrifugal force, the powder falls along the inner wall of the mold through the discharge hole. Even if there is a time difference in the direction of the hopper opening and discharging, the powder can be brought to different positions and dropped by the fast-rotating (more than 2 revolutions per second) discharge plate. In this way, the circumferential discharge is basically uniform, the wall thickness of the formed blank can be uniform, the size and shape consistency is good, and mass production is convenient.

[0018] Preferably, in the aforementioned rotary distributor for a dry bag isostatic pressing machine, the outer wall of the annular outer disc is provided with an outer disc belt slot for connecting to a reduction pulley of a drive mechanism of the dry bag isostatic pressing machine via a belt transmission. The belt can be guided through the outer disc belt slot on the annular outer disc to an external motor reducer pulley, and the motor drives the reducer to rotate, thereby driving the distributor to rotate, thereby achieving rotary distribution of the materials.

[0019] Preferably, in the aforementioned rotary distributor for a dry bag isostatic pressing machine, the outer wall of the annular housing is provided with a housing belt slot for connecting to a reduction pulley of a drive mechanism of the dry bag isostatic pressing machine via a belt transmission. Alternatively, a belt can be routed through the housing belt slot on the annular housing to an external motor reducer pulley, with the motor driving the reducer to rotate, thereby driving the distributor to rotate, thereby achieving rotary distribution.

[0020] Preferably, in the rotary distributor for a dry bag isostatic pressing machine, bearing balls are provided between the inner wall of the annular outer disc and the outer wall of the annular inner disc for relative rotation thereof. The relative rotation of the annular inner disc and the annular outer disc is achieved by the bearing balls.

[0021] Preferably, in the rotary distributor for the dry bag isostatic pressing machine, a sealing ring is provided between the inner wall of the annular outer disc and the outer wall of the annular inner disc. This prevents dust generated during the rotation and falling of the powder from leaking out, thereby polluting the external environment and affecting the respiratory health of the operator.

[0022] Preferably, in the rotary distributor for a dry bag isostatic pressing machine, an oil filling port is provided on the inner wall of the annular inner disk. Oil can be injected through the oil filling port into the space between the annular inner disk and the annular outer disk for lubrication, thereby ensuring smoother and easier relative rotation of the annular inner disk and the annular outer disk.

[0023] Preferably, in the aforementioned rotary distributor for a dry bag isostatic pressing machine, the top surface of the annular inner disk is higher than the top surface of the annular outer disk, and the annular inner disk is provided with bolt holes for convenient installation. The annular inner disk can be bolted to a mounting plate within the dry bag isostatic pressing machine via the bolt holes, facilitating maintenance, disassembly, and replacement of blanking plates with different hole diameters.

[0024] Preferably, in the aforementioned rotary distributor for a dry bag isostatic pressing machine, the blanking plate, annular outer disc, and annular outer shell are annular in shape, and the outer diameter of the annular outer disc is the same as the outer diameter of the annular outer shell and the diameter of the blanking plate. The centrifugal force generated during the circular rotation facilitates uniform distribution of the powder, ensuring that the resulting blanks are more uniform and aesthetically pleasing.

[0025] Preferably, in the rotary distributor for the dry bag isostatic pressing machine, the discharge hole is any one of square, rectangular, circular, sector-shaped, or elliptical. Different types of discharge holes can be selected as needed, but when selecting, consideration should be given to minimizing powder accumulation in the distributor to ensure more uniform formed blanks.

[0026] Preferably, in the aforementioned rotary distributor for a dry bag isostatic pressing machine, a weight-reducing cavity extending through the larger end of the guide cone is defined within the guide cone. This reduces the output driving force of the dry bag isostatic pressing machine's drive mechanism, conserving energy, and enabling the optional installation of the rotary distributor with a smaller driving force.

[0027] Preferably, in the above-mentioned rotary distributor for dry bag isostatic pressing machine, the discharge hole is any one of square, rectangular, fan-shaped, circular, and elliptical, but it should be considered that the accumulated powder left in the distributor is as little as possible.

[0028] The present invention also provides a forming machine for isostatic pressing of dry bags, comprising an upper crossbeam, a distributor mounting assembly, the rotary distributor in the above technical solution, and an annular cylinder:

[0029] The upper plate surface of the upper crossbeam is provided with a through hole, which is connected to the blanking mechanism; limiting columns are fixed on both sides of the lower plate surface of the upper crossbeam, and a driving mechanism is fixed on one side plate surface of the upper crossbeam;

[0030] The distributor mounting assembly is in an inverted cylindrical shape and includes a top plate and side plates. The top plate is detachably connected to the lower plate surface of the upper crossbeam. A feed hole communicating with the through hole is provided on the top plate.

[0031] The rotary distributor is arranged in the inner cavity of the barrel of the distributor mounting assembly, the annular inner disk of the rotary distributor is detachably connected to the top plate, and the annular cavity of the annular inner disk is communicated with the discharge hole; the annular outer shell or the annular outer disk is in transmission connection with the driving mechanism;

[0032] The inner wall of the annular cavity of the annular cylinder is slidably connected to the outer wall of the side plate. A ceramic forming mechanism is fixed in the annular cavity of the annular cylinder, and a ceramic filler position is provided in the ceramic forming mechanism. A lower cylinder piston mechanism is fixed at the lower part of the annular cylinder.

[0033] Through the above technical solution, when the forming machine is working, the rotary feeder can achieve rapid feeding by feeding while rotating. The wall thickness of the final processed blank is more uniform, avoiding the problem of depression on the upper part of the blank, and at the same time greatly improving the processing efficiency.

[0034] It can be seen from the above technical solution that compared with the prior art, the present invention discloses a rotary distributor for a dry bag isostatic pressing machine. The detachable connection method facilitates the replacement of blanking plates of different sizes. The distributor is easy to install. The wall thickness of the blank formed by the distributor is uniform, the integrity of the blank is excellent, and the processing efficiency is high. At the same time, powder dust can be avoided during use to protect the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0066] See attached Figures 1-3 The embodiment of the present invention discloses a rotary distributor for a dry bag isostatic pressing machine, comprising:

[0067] Blanking plate 4;

[0068] The guide cone 5, the large end of the guide cone 5 is detachably connected to the blanking plate 4;

[0069] The annular housing 3 is detachably connected to the circumferential side of the upper end of the blanking plate 4. A powder flow gap 8 is reserved between the inner wall of the annular housing 3 and the outer wall of the guide cone 5. The powder flow gap 8 corresponds to a plurality of blanking holes 41 spaced apart on the annular band of the blanking plate 4. The blanking holes 41 are radially arranged along the center of the blanking plate 4.

[0070] an annular outer disk 1, the lower end annular surface of the annular outer disk 1 is detachably connected to the upper end annular surface of the annular outer shell 3;

[0071] The annular inner disk 2 is sleeved in the annular cavity of the annular outer disk 1 and is rotatably connected to the annular outer disk 1. The annular cavity of the annular inner disk 2 is connected to the inner cavity of the annular outer shell 3. The small end of the guide cone 5 extends into the annular cavity of the annular inner disk 2.

[0072] Among them, the annular shell 3 is transmission-connected to the driving mechanism.

[0073] In this embodiment, the blanking hole is rectangular.

[0074] In this embodiment, a bearing ball 6 is provided between the inner wall of the annular outer disk 1 and the outer wall of the annular inner disk 2 for relative rotation. The bearing ball 6 enables the annular inner disk 2 and the annular outer disk 1 to rotate easily.

[0075] In this embodiment, a shell belt slot 31 is provided in the upper middle portion of the annular shell 3, so that the annular shell 3 forms an hourglass-like structure; the position of the shell belt slot 31 is opposite to the position of the bearing ball 6 and is on the same vertical plane. The shell belt slot 31 is connected to the driving mechanism of the isostatic pressing machine, and the rotation of the rotary distributor is realized by the rotation of the annular shell 3.

[0076] In order to further optimize the above technical solution, a dust-proof sealing ring 7 is provided between the inner wall of the annular outer disk 1 and the outer wall of the annular inner disk 2 .

[0077] In order to further optimize the above technical solution, an oil filling port is opened on the inner wall of the annular inner disk 2 for injecting oil between the annular inner disk 2 and the annular outer ring 1 to increase lubrication and make their relative rotation smoother.

[0078] To further optimize the above technical solution, the top surface of the annular inner disk 2 is higher than the top surface of the annular outer disk 1, and bolt holes 21 are provided on the annular inner disk 2 for easy installation. During use, the annular inner disk 2 can be fixed to the mounting mechanism inside the isostatic pressing machine. Since the annular outer disk 1 is detachably connected to the annular outer shell 3, when the driving mechanism drives the annular outer shell 3 to rotate, the annular inner disk 2 remains fixed, while the annular outer disk 3 rotates synchronously, thereby achieving uniform material distribution.

[0079] In order to further optimize the above technical solution, the blanking plate 4 , the annular outer disk 1 and the annular shell 3 are in the shape of a circular ring, and the outer diameter of the annular outer disk 1 is the same as the outer diameter of the annular shell 3 and the diameter of the blanking plate 4 .

[0080] In order to further optimize the above technical solution, a weight-reducing cavity is opened in the guide cone 5 and passes through its large end. The weight-reducing cavity can reduce the output of the driving force of the driving mechanism and increase the centrifugal force generated during the rotation of the distributor. Example 2:

[0086] The distributor mounting assembly 9 is in the shape of an inverted cylinder and includes a top plate 91 and a side plate 92. The top plate 91 is detachably connected to the lower plate surface of the upper crossbeam 14. A feeding hole is provided on the top plate 91 and is connected to the through hole.

[0087] The rotary distributor is arranged in the inner cavity of the distributor mounting assembly 9. The annular inner disk 2 of the rotary distributor is detachably connected to the top plate 91, and the annular cavity of the annular inner disk 2 is connected to the discharge hole; the annular outer shell 3 is in transmission connection with the driving mechanism 16;

[0088] The inner wall of the annular cavity of the annular cylinder is slidably connected to the outer wall of the side plate 92. A ceramic forming mechanism 12 is fixed in the annular cavity of the annular cylinder. A ceramic filler position is preset between the ceramic forming mechanism 12 and the inner wall of the annular cylinder; a lower cylinder piston mechanism 13 is fixed to the lower part of the annular cylinder.

[0089] In order to further optimize the above technical solution, the unloading mechanism 15 includes a hopper 151 filled with ceramic powder; a gate 152 for controlling its opening and closing is provided at the hopper mouth below the hopper 151, and the opening and closing of the gate 152 is controlled by a cylinder 154.

[0090] In order to further optimize the above technical solution, the ceramic forming mechanism 12 includes an isostatic pressing film 123, and an isostatic pressing medium liquid 121 is filled between the outer periphery of the isostatic pressing film 123 and the inner wall of the annular cylinder; and further includes an isostatic pressing core mold 122, which is fixed in the middle of the annular cavity of the annular cylinder, and a filler gap is preset between the outer periphery of the isostatic pressing core mold 122 and the inner side surface of the isostatic pressing film 123;

[0091] In order to further optimize the above technical solution, the lower cylinder piston mechanism 13 includes a floating mold beam 131 fixed on the annular surface of the lower end of the annular cylinder body, and a core connecting plate 132 is fixed to the lower end of the annular cavity of the annular cylinder body for connecting with the lower end of the isostatic pressing film 123; the lower plate surface of the core connecting plate 132 is detachably connected to a movable beam 133, and a connecting flange 134 is detachably connected under the movable beam 133, and the lower part of the connecting flange 134 is fixed to the lower cylinder piston rod 135.

[0096] The ceramic powder falls along the discharge hole 41 and is thrown out to the filling position between the isostatic pressing core 122 and the isostatic pressing film 123 below. When the powder on the filling position reaches the required amount, the gate 152 is closed.

[0097] The annular cylinder body moves upward under the push of the lower cylinder piston rod 135 until the upper end ring surface of the annular cylinder body presses against the limit column 10; at this time, the distributor mounting assembly 9 slides to the pressing position of the annular cylinder body, and then the ceramic cylinder forming process of pressurization, pressure maintenance and pressure relief is carried out.

[0098] The isostatic pressing machine provided by the present invention can quickly complete the laying of materials, and the thickness of the processed and formed blanks is uniform and the upper integrity performance is good, which solves the problems of poor aesthetics and uneven wall thickness of the blanks formed by traditional isostatic pressing machines. The setting of the sealing ring effectively reduces the occurrence of dust, protects the on-site processing environment, and reduces damage to the respiratory system of on-site operators.
