Description

Technical Field

[0001] This utility model belongs to the field of ceramic target processing technology, specifically, it relates to a ceramic target forming device. Background Technology

[0002] Currently, the main forming methods for ceramic rotating target blanks include extrusion, in-situ colloidal solidification, slip casting, and cold isostatic pressing. Extrusion, in-situ colloidal solidification, and slip casting can all produce near-net-shape blanks, which has certain advantages in the production of irregularly shaped parts. However, the blanks obtained by extrusion contain a large amount of organic matter and water, making it difficult to sinter densely. In-situ colloidal solidification also contains a large amount of organic matter and water, making it prone to cracking during drying of large-size blanks, and it is difficult to obtain ultra-high density. Slip casting has relatively strict requirements on powder particle size and distribution, slurry, and porous molds, and the drying control of the green blank is strict, making it technically challenging.

[0003] After searching for ring-shaped and cylindrical shapes, the applicant found that the existing technology separates the shaping methods for these types of shapes, which requires different equipment for shaping ring-shaped and cylindrical shapes, thus increasing the shaping cost.

[0004] Furthermore, in existing technologies, after shaping, the stamping part is directly separated from the ceramic target. However, due to the nature of the ceramic target itself, it is quickly ejected. Under the force of ejection, the tightness of the edge of the ceramic target may be affected, which will affect subsequent processing and the quality of the finished product.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the technical problem of ceramic target shaping, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A ceramic target forming device includes a shaping component for shaping the ceramic target. The shaping component includes an operating table, a mounting frame, a base, a mold, a central stamping column, and a side stamping ring. The mounting frame is fixedly connected to the operating table, and the base is fixedly connected to the middle of the operating table. The mold is elastically set to the base. The central stamping column and the side stamping ring are both mounted on the mounting frame and driven by components on the mounting frame. The side stamping ring is sleeved on the central stamping column.

[0008] In a preferred embodiment of this utility model, a hydraulic press is fixedly connected to the mounting frame, the output end of the hydraulic press is fixedly connected to the central stamping column through a coupling, and the output end of the hydraulic press is drivenly connected to the side stamping ring.

[0009] In a preferred embodiment of this utility model, a reciprocating motor is fixedly connected to the bottom of the operating table, and a follower rod is connected to the output end of the reciprocating motor through a coupling. A sliding rod is fixedly connected to the end of each follower rod, and each sliding rod is fixedly connected to the same support rod.

[0010] In a preferred embodiment of this utility model, the support rod is rotatably connected to the coupling at the output end of the hydraulic press, and limit grooves are symmetrically opened on the operating table, with a corresponding sliding rod passing through each limit groove.

[0011] In a preferred embodiment of this utility model, mounting rods are symmetrically arranged on the support rod, and a micro vibration module is rotatably connected to the bottom of each mounting rod. A ring groove is opened on the side stamping ring, and each micro vibration module abuts against the inner wall of the ring groove.

[0012] In a preferred embodiment of this utility model, the base is symmetrically provided with limiting posts, which are fixedly connected to the base. The base is provided with multiple spring plates, and each spring plate is fixedly connected to a sliding rod at its end. Each sliding rod is slidably connected to the base.

[0013] In a preferred embodiment of this utility model, each of the spring plates abuts against a lifting plate, and each lifting plate is slidably connected to the inner wall of the base.

[0014] In a preferred embodiment of this utility model, a locking block is fixedly connected to the middle of the lifting plate, and a locking sleeve is engaged on the locking block, with the locking sleeve being fixedly connected to the mold.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This ceramic target forming device allows for the manual feeding of a quantitative amount of ceramic target material into a mold. The central stamping column and the side stamping ring move downwards synchronously. An annular space and a cylindrical space can be formed between the mold, the central stamping column, and the side stamping ring. Thus, in the shaping of the ceramic target material, the stamping depth of the central stamping column and the side stamping ring within the base is controlled to achieve control over the shaping of the ceramic target material. This device enables the shaping of annular and cylindrical ceramic target materials using a single device.

[0017] 2. In this ceramic target forming device, the mounting rod drives the micro-vibration module to move within the annular groove. Due to the gaps reserved between components for movement, the micro-vibration module inevitably has space to transmit vibration force as it moves within the annular groove. Through stable and continuous vibration force, the movement state and interaction of powder particles are controlled between the side stamping ring and the end of the shaped ceramic target, thereby achieving microstructure optimization. This makes the shaped ceramic target more compact and facilitates the separation of the ceramic target from the central stamping column and the side stamping ring.

[0018] 3. In this ceramic target forming device, the spring plate applies deformation force to the lifting plate, and the lifting plate pushes the mold upward. Initially, the lifting plate is not completely separated from the central stamping column, but separates slowly until the central stamping column is completely pulled out of the mold. This avoids the traditional rapid ejection, which may affect the edge tightness of the ceramic target under the ejection force, thus affecting subsequent processing and finished product quality.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] Please see Figure 1-5A ceramic target forming device includes a shaping component for shaping the ceramic target. The shaping component includes an operating table 1, a mounting frame 2, a base 3, a mold 31, a central stamping column 4, and a side stamping ring 41. The mounting frame 2 is fixedly connected to the operating table 1, and the base 3 is fixedly connected to the middle of the operating table 1. The mold 31 is elastically set to the base 3. The central stamping column 4 and the side stamping ring 41 are both set on the mounting frame 2 and driven by components on the mounting frame 2. The side stamping ring 41 is sleeved on the central stamping column 4.

[0029] The ceramic target material is quantitatively fed into the mold 31 by manual operation. The central stamping column 4 and the side stamping ring 41 move downward synchronously. The mold 31, the central stamping column 4 and the side stamping ring 41 can form an annular space and a cylindrical space. Thus, in the shaping of the ceramic target material, the stamping depth of the central stamping column 4 and the side stamping ring 41 in the base 3 is controlled to achieve the shaping of the ceramic target material. This device realizes the annular and cylindrical shaping of the ceramic target material in one device.

[0030] The mounting bracket 2 is fixedly connected to a hydraulic press 21. The output end of the hydraulic press 21 is fixedly connected to the central stamping column 4 through a coupling. The output end of the hydraulic press 21 is also connected to the side stamping ring 41 through a transmission connection.

[0031] After a certain amount of ceramic target material is put into the mold 31, the mounting frame 2, with the cooperation of the output end and the coupling, drives the central stamping column 4 and the side stamping ring 41 downward. The central stamping column 4 enters the mold 31 first, and the central stamping column 4 extrudes and diffuses the ceramic target material to the bottom and the periphery to form a basic shape. The mounting frame 2 controls the extrusion depth through an electronic control program. When there is a gap between the central stamping column 4 and the bottom of the mold 31, the ceramic target material forms a cylindrical shape. When there is no gap between the central stamping column 4 and the bottom of the mold 31, the ceramic target material forms a ring shape. The side stamping ring 41 is used to shape the end of the ceramic target material.

[0032] The bottom of the operating table 1 is fixedly connected to a reciprocating motor 5. The output end of the reciprocating motor 5 is connected to a follower rod 51 through a coupling. The ends of the follower rods 51 are fixedly connected to sliding rods 52. Each sliding rod 52 is fixedly connected to the same support rod 53. The support rod 53 is rotatably connected to the coupling at the output end of the hydraulic press 21. Limiting grooves 11 are symmetrically opened on the operating table 1. Each limiting groove 11 is connected to a corresponding sliding rod 52. Mounting rods 54 are symmetrically arranged on the support rods 53. The bottom of each mounting rod 54 is rotatably connected to a micro vibration module 55. A ring groove 56 is opened on the side stamping ring 41. Each micro vibration module 55 abuts against the inner wall of the ring groove 56.

[0033] After the ceramic target material is roughly shaped and stamped under the operation of the central stamping column 4, and because the side stamping ring 41 moves with the output end of the hydraulic press 21, the side stamping ring 41 stamps the end of the ceramic target material, making the end of the ceramic target material flat. The reciprocating motor 5 is driven to rotate by the follower rod 51 through the cooperation of the output end and the coupling. The follower rod 51 drives the sliding rod 52, the sliding rod 52 drives the support rod 53, the support rod 53 drives the mounting rod 54, and the mounting rod 54 drives the micro vibration module 55 to move in the annular groove 56. Because of the gap reserved between the components for movement, the micro vibration module 55 must have space to transmit vibration force when it moves in the annular groove 56. Through stable and continuous vibration force, the movement state and interaction of powder particles are controlled by the side stamping ring 41 and the end of the ceramic target material after shaping, thereby achieving microstructure optimization, making the ceramic target material more compact after shaping, and facilitating the separation of the ceramic target material from the central stamping column 4 and the side stamping ring 41.

[0034] The central stamping column 4 has a hollow structure inside, so when the side stamping ring 41 is subjected to the vibration force transmitted by the micro vibration module 55, the vibration force can be transmitted in a more optimized way, and it is convenient for subsequent processing.

[0035] The reciprocating motor 5, through reciprocating drive, transmits vibration force evenly and repeatedly, improving the compactness and uniformity of the ceramic target material after shaping, and the limiting groove 11 provides space for the sliding rod 52 to move.

[0036] It is worth noting that the micro vibration module 55 includes a battery, a drive circuit, and a vibration module. The vibration module includes multiple micro vibration sources, and the vibration module is electrically connected to the drive circuit. The micro vibration module 55 has been fully disclosed in an electric toothbrush with announcement number CN220293697U, and will not be described in detail here.

[0037] The base 3 is symmetrically provided with limit posts 33, which are fixedly connected to the base 3. The base 3 is provided with multiple spring plates 34, and each spring plate 34 is fixedly connected to a slide rod 35 at its end. Each slide rod 35 is slidably connected to the base 3.

[0038] Each spring plate 34 is abutted against a lifting plate 32, and each lifting plate 32 is slidably connected to the inner wall of the base 3.

[0039] Among them, the middle part of the lifting plate 32 is fixedly connected to the locking block 36, the locking block 36 is fitted with the locking sleeve 37, and the locking sleeve 37 is fixedly connected to the mold 31.

[0040] During operation, mold 31 is first driven downward by side stamping ring 41. Mold 31 then drives lifting plate 32 downward to compress spring plate 34, causing spring plate 34 to deform and push both ends outward. Slide rod 35 at the end of spring plate 34 moves accordingly and slides between slide rod 35 and base 3, thereby guiding the deformation direction of spring plate 34. This prevents it from being squeezed against the inner wall of base 3 due to lack of guidance in the limited space within base 3, which could damage internal components. After lifting plate 32 reaches the designated position, it abuts against limiting post 33, restricting the position of limiting post 33 and preventing irreversible deformation of spring plate 34 due to continuous downward movement. After shaping, spring plate 34 applies deformation force. The lifting plate 32 pushes the mold 31 upward. Initially, the lifting plate 32 and the central stamping column 4 are not completely separated, but are separated slowly until the central stamping column 4 is completely pulled out of the mold 31. This avoids the traditional rapid ejection, which may affect the edge tightness of the ceramic target material under the ejection force, affecting subsequent processing and finished product quality. In addition, the mold 31 can be removed from the base 3 by setting the clamping block 36 and the clamping sleeve 37. During demolding, the mold 31 only needs to be flipped over, and the ceramic target material can be removed from the mold 31 with the help of auxiliary tools. For example, gently hitting the clamping sleeve 37 end of the mold 31 will cause slight vibration and the ceramic target material will be ejected.
