Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cold isostatic pressing equipment, in particular to a ceramic body cold isostatic pressing equipment. BACKGROUND

[0002] As an advanced powder forming technology, the core of cold isostatic pressing forming is to uniformly transmit pressure to the powder material wrapped in a flexible mold in a high-pressure environment through a fluid medium, realize omnidirectional pressure in all directions, and thus promote the close combination of powder particles to form a green body with high density and uniform structure. In the field of precision ceramics, cold isostatic pressing forming technology has irreplaceable application value. It can effectively solve the problems of uneven green body density and many internal defects in traditional forming methods, significantly improve the density and strength of the green body, lay a good foundation for the subsequent sintering process, and ultimately ensure that the precision ceramic products meet the stringent application standards in mechanical properties, wear resistance and high temperature resistance. For example, CN114851623B discloses a cold isostatic pressing forming equipment capable of automatic feeding, which comprises upper and lower storage tanks and a forming mold. The top of the forming mold has a feeding port. The bottom of the storage tank is connected with a impurity removal device. The bottom of the impurity removal device is connected with a weighing and metering equipment through a butterfly valve. The discharge part of the weighing and metering equipment is connected with a feeding pipe. The weighing and metering equipment feeds the forming mold through the feeding pipe and the feeding port.

[0003] However, in the prior art, when the cold isostatic pressing forming equipment is used for forming processing of ceramic powder, the surface energy of the nanoscale ceramic powder is high, and hard agglomerates are easily formed. The friction between these agglomerates is large, which leads to poor flowability of the powder as a whole. Nanoscale powder is easily accumulated in the form of "small hills", and it is difficult to naturally fill the corner parts of the rubber sleeve. Irregularly shaped powder is easy to form dead corners that cannot be filled at the corners of the rubber sleeve, resulting in local powder deficiency. After cold isostatic pressing forming of the ceramic green body, density distribution is uneven, and pores and voids are easily generated at the corners and corners due to insufficient powder filling, thereby increasing the risk of deformation and cracking during the subsequent sintering process, reducing product qualification rate and performance stability.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0020] Embodiment one: refer toFigures 1-8 The utility model discloses a kind of ceramic body cold isostatic pressing equipment, including forming mechanism 1, and forming mechanism 1 side is equipped with feeding mechanism 2, and forming mechanism 1 bottom is equipped with vibration mechanism 3, feeding mechanism 2 includes feeding hopper 21, feeding hopper 21 upper portion is respectively fixedly connected with No. The utility model discloses a kind of ceramic body cold isostatic pressing equipment, including forming mechanism 1, and forming mechanism 1 side is equipped with feeding mechanism 2, and forming mechanism 1 bottom is equipped with vibration mechanism 3, feeding mechanism 2 includes feeding hopper 21, feeding hopper 21 upper portion is respectively fixedly connected with No. The forming mechanism 1 comprises a fixed frame 11, a pressurizing assembly 12 mounted on the upper portion of the fixed frame 11, a base 14 fixedly connected with the fixed frame 11, and a forming die 13 arranged above the base 14 and located above the pressurizing assembly 12, wherein the grinding head 29 is in the shape of a circular truncated cone, the upper hopper 21 and the discharge box 25 are fixedly connected by elastic material, the two upper feeding pipes 26 are fixedly connected with the upper portion of the forming die 13 and symmetrically arranged on the surface of the forming die 13, the auxiliary mechanism 5 is mounted on the bottom of the discharge box 25 and used for shaking the discharge box 25, the vibration mechanism 3 is mounted on the bottom of the forming mechanism 1 and used for vibrating the raw material entering the forming mechanism 1, and the vibration mechanism 3 is used for driving the auxiliary mechanism 5 to operate, wherein the auxiliary mechanism 5 comprises a third bevel gear 51 and a second limiting frame 56, the third bevel gear 51 is fixedly connected with the output end of the second servo motor 31, the surface of the third bevel gear 51 is engaged with a bevel gear connecting shaft 52, the upper portion of the bevel gear connecting shaft 52 is engaged with a fourth bevel gear 53, the surface of the fourth bevel gear 53 is fixedly connected with a third connecting shaft 54, the surface of the third connecting shaft 54 is fixedly connected with a second cam 55, the second limiting frame 56 is fixedly connected with the bottom of the discharge box 25, and the bottom of the second limiting frame 56 is in contact with the second cam 55, the telescopic frame 27 is mounted on the bottom of the discharge box 25, and the bevel gear connecting shaft 52 is composed of two bevel gears and a fixed rod.

[0021] In the embodiment, when the device starts to process the ceramic powder, the ceramic powder of nanometer size or irregular shape is firstly put into the discharge pipe 23 through the feeding opening at the top of one end of the discharge pipe 23, at this time, the first servo motor 22 is started, and the output end of the first servo motor 22 synchronously drives the auger rod 28, the grinding head 29 and the first bevel gear 41 to rotate, the auger rod 28 rotates in the discharge pipe 23 to push the powder in the discharge pipe 23 to the grinding pipe 24, and the grinding head 29 in the shape of a circular truncated cone rotates synchronously with the auger rod 28 to cooperate with the inner wall of the grinding pipe 24 to grind the powder, so as to break the hard agglomerates formed by the nanometer powder and reduce the friction between the particles to improve the flowability of the powder. The ground powder enters the discharge box 25 and is then conveyed to the forming die 13 of the forming mechanism 1 through the two symmetrically arranged upper feeding pipes 26. Since the upper hopper 21 and the discharge box 25 are connected by elastic material, and the auxiliary mechanism 5 is driven by the second servo motor 31 to rotate the second cam 55 through the third bevel gear 51, the bevel gear connecting shaft 52 and the fourth bevel gear 53, so that the second limiting frame 56 pushes the discharge box 25 to shake up and down, the discharge box 25 generates high-frequency micro-vibration under the action of elastic connection, so as to avoid the powder from being accumulated and blocked in the box and ensure that the powder continuously and uniformly enters the upper feeding pipe 26. At the same time, the first bevel gear 41 drives the second connecting shaft 43 to rotate through the meshing second bevel gear 42, so that the crank 44 drives the connecting rod piston assembly 45 to reciprocate in the shell 46. When the piston moves outward, the ambient air is filtered through the air filter 49 and enters the shell 46 through the air inlet pipe 48 (the one-way valve 410 ensures that the air enters in one direction); when the piston moves inward, the compressed air is sent into the upper hopper 21 through the air outlet pipe 47, forming a pulse airflow. This airflow can not only blow away the powder agglomerates in the upper hopper 21, but also accelerate the flow of powder to the discharge pipe 23, reducing the "mountain-shaped" accumulation. During the process of powder entering the forming mold 13, the second servo motor 31 drives the vibration mechanism 3 to operate, the first connecting shaft 32 drives the first cam 33 to rotate, and the first limiting frame 34 moves up and down, and the mounting frame 37 and the vibration table 38 are driven to vibrate at high frequency through the telescopic rod 35 and the first spring 36. The forming mold 13 vibrates synchronously with the vibration table 38. This vibration can break the "arch bridge" structure of the powder in the mold, cooperate with the symmetrical feeding of the double feeding pipe 26, guide the powder to uniformly fill the mold corners and corners, reduce the local lack of powder, and limit the shaking amplitude of the vibration table 38 through the cooperation of the limiting rod 310 and the fixed plate 39. The second spring 311 buffers the vibration impact, ensuring the stable vibration of the forming mold 13. The cooperation of the grinding head 29 and the grinding pipe 24 directly breaks the hard agglomerates, and the pulse airflow of the pushing mechanism 4 blows away the agglomerates, which significantly improves the flowability of the nano-sized powder, solves the problem of "large friction force of agglomerates leading to poor flowability", and cooperates with the symmetrical feeding of the double feeding pipe 26 to make the powder more easily fill the mold dead corners, reduce the local lack of powder, and alleviate the problem of "uneven filling". The airflow of the pushing mechanism 4 is filtered through the air filter 49 to avoid impurities polluting the powder, and at the same time, the pulse airflow can discharge the air in the powder gap, reducing the risk of air holes in subsequent molding.

[0022] Example two: according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the lower part of the feeding mechanism 2 is fixedly connected with a pushing mechanism 4, the pushing mechanism 4 comprises a first bevel gear 41, a connecting rod piston assembly 45 and a shell 46, the first bevel gear 41 is fixedly connected with the output end of the first servo motor 22, the lower part of the first bevel gear 41 is engaged with a second bevel gear 42, the bottom of the second bevel gear 42 is fixedly connected with a second connecting shaft 43, the bottom of the second connecting shaft 43 is fixedly connected with a crank 44, the crank 44 is movably connected with the connecting rod piston assembly 45, the end of the connecting rod piston assembly 45 is slidably connected with the inside of the shell 46, the end of the shell 46 is fixedly connected with an exhaust pipe 47 and an air inlet pipe 48 respectively, the exhaust pipe 47 is fixedly communicated with the feeding hopper 21, the end of the air inlet pipe 48 is provided with a one-way valve 410, the vibrating mechanism 3 comprises a second servo motor 31 and a first limiting frame 34, the second servo motor 31 is fixedly connected with the fixed frame 11, and the second servo motor 31 is fixedly connected with a first connecting shaft 32, the upper part of the first connecting shaft 32 is fixedly connected with a first cam 33, the lower part of the first limiting frame 34 is in contact with the first cam 33, and the upper part of the first limiting frame 34 is fixedly connected with an extension rod 35, the upper part of the extension rod 35 is fixedly connected with a mounting frame 37, the upper part of the mounting frame 37 is fixedly connected with a vibrating table 38, the vibrating table 38 is fixedly connected with the bottom of the forming mold 13, the surface of the extension rod 35 is provided with a first spring 36, one end of the first spring 36 is fixedly connected with the first limiting frame 34, and the other end of the first spring 36 is fixedly connected with the mounting frame 37, the outer side of the vibrating table 38 is fixedly connected with a fixed plate 39, the upper part of the base 14 is fixedly connected with a limiting rod 310, the limiting rod 310 is inserted with the fixed plate 39, and the surface of the limiting rod 310 is provided with a second spring 311, one end of the second spring 311 is fixedly connected with the fixed plate 39, and the other end of the second spring 311 is fixedly connected with the top of the limiting rod 310.

[0023] In this embodiment, in the forming processing of the nano-scale ceramic powder, the details of the device are further optimized to improve the feeding and filling effect. The circular table structure of the grinding head 29 allows it to form a "tapered" extrusion grinding on the powder when rotating in the grinding pipe 24. Compared with the cylindrical grinding head, it can more efficiently break up agglomerates of different particle sizes, and the ground powder particles are more uniformly distributed, further improving the flowability. The elastic material connection (such as rubber material) between the feeding hopper 21 and the discharge box 25 can produce elastic deformation when the discharge box 25 is shaken by the auxiliary mechanism 5, amplify the shaking amplitude, avoid the powder from clogging at the connection between the discharge box 25 and the feeding pipe 26, and ensure the continuity of feeding. The one-way valve 410 of the pushing mechanism 4 is closed when the piston moves outward, preventing the powder in the feeding hopper 21 from being sucked back into the shell 46; when the piston moves inward, the airflow pressure output by the exhaust pipe 47 is stable (achieved by uniform rotation of the crank 44), which can accurately control the air pressure in the feeding hopper 21, avoiding both the pressure being too large to cause the powder to splash and the powder from being effectively blown away. In the vibration mechanism 3, the first spring 36 on the surface of the telescopic rod 35 and the second spring 311 on the surface of the limiting rod 310 form a "double-spring buffer system". When the first cam 33 is driven by the second servo motor 31 to rotate at high speed, the double-spring can absorb the vibration impact, so that the amplitude of the vibration table 38 is stabilized in the range of 0.5-2mm (adapted to the filling requirements of nano-powder), which not only ensures that the powder can flow to the corner of the mold, but also avoids the powder stratification caused by violent vibration. The forming mold 13 is rigidly connected with the vibration table 38, which ensures that the vibration energy is efficiently transmitted to the inside of the mold; the two feeding pipes 26 are symmetrically distributed on the surface of the forming mold 13, so that the powder enters the mold from both sides at the same time, reducing the density deviation caused by unilateral feeding, and cooperating with the vibration to further improve the uniformity of the green body density. The combination of the circular-truncated-cone-shaped grinding head 29 and the elastic connection structure strengthens the crushing and conveying capacity of hard agglomerates, solves the problem of "nano-powder easy to accumulate into a small hill", and the vibration system with double-spring buffer cooperates with the symmetric feeding pipe 26 to reduce the filling density deviation of the powder in the mold, significantly reduces the deformation and cracking risk of subsequent sintering, and the design of the one-way valve 410 and the air filter element 49 not only ensures the stability of the airflow system, but also avoids the pollution of the powder, and improves the performance stability of the ceramic green body.
