Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, specifically to a deformation-resistant ceramic green body sintering support. Background Technology

[0002] Sintering is one of the key processes in ceramic production. When ceramic blanks are sintered at high temperatures, they are prone to deformation due to their own weight and uneven heating, which seriously affects the quality and yield of ceramic products.

[0003] Currently, the most common sintering method for ceramic blanks is to place the blanks directly on ordinary sintering pads or supports for sintering. Traditional sintering supports have simple structures and limited support and fixation effects on ceramic blanks. They cannot effectively limit the deformation trend of the blanks at high temperatures. Furthermore, uneven heat transfer during sintering can lead to inconsistent shrinkage in different parts of the blank, further aggravating the degree of deformation.

[0004] In addition, some traditional supports are difficult to adapt to ceramic blanks of different shapes and sizes, have poor versatility, and require frequent replacement of supports of different specifications, which increases production costs and the complexity of production operations. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a deformation-resistant ceramic blank sintering support, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a deformation-resistant ceramic blank sintering support, comprising: a base, with support columns fixedly connected to the four corners of the top of the base, a support plate provided in the middle of the support columns, a plurality of ventilation holes evenly opened on the surface of the support plate, auxiliary fixing components provided on both sides of the top of the support plate, the auxiliary fixing components including a slide rail, a slide rod fixedly connected to the middle of the slide rail, a second slider slidably connected to the surface of the slide rod, a spring sleeved on the surface of the slide rod, a clamping component provided at the top of the second slider, and a support mechanism provided between the support plate and the base.

[0008] Furthermore, high-temperature resistant anti-slip pads are fixedly connected to the four corners of the base, a sliding groove is opened in the middle of the support column, and a first slider is fixedly connected to the four corners of the support plate. The first slider is slidably connected inside the sliding groove.

[0009] Furthermore, limit grooves are provided on both sides of the slide rail, and limit blocks are fixedly connected to both sides of the second slider. The limit blocks are slidably connected inside the limit grooves, and the second slider is slidably connected to the middle of the slide rail.

[0010] Furthermore, the spring is made of high-temperature resistant silicon nitride material, with one end of the spring abutting against one side of the second slider and the other end of the spring abutting against one end of the slide rail.

[0011] Furthermore, a groove is provided in the middle of the bottom end of the base, and the support mechanism includes a threaded rod, which is rotatably connected to the middle of the base. A knob is fixedly connected to the bottom end of the threaded rod, and the knob is located inside the groove.

[0012] Furthermore, the top of the threaded rod is threadedly connected to a threaded sleeve, and the top of the threaded sleeve is fixedly connected to the middle of the bottom of the support plate.

[0013] Furthermore, the clamping assembly includes an L-shaped support rod, the bottom end of which is fixedly connected to the top of the second slider, and the other end of which is rotatably connected to a clamping block, which is arc-shaped.

[0014] Furthermore, a protective pad is fixedly connected to the surface of the clamping block, and several spherical protrusions are evenly distributed on the surface of the protective pad.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] 1. The adjustable support mechanism allows for flexible adjustment based on the height of the ceramic blank, ensuring it is positioned appropriately. Auxiliary fixing and clamping components further enhance the support, clamping the ceramic blank to restrict displacement and deformation during sintering. Ventilation holes on the support plate facilitate gas escape, ensuring uniform heating and effectively preventing deformation during sintering, thus improving product quality and yield.

[0017] 2. With the support columns and high-temperature resistant anti-slip pads, the support columns are made of high-temperature resistant and high-strength ceramic materials, and the four corners of the bottom of the base are equipped with high-temperature resistant anti-slip pads. The overall structure can remain stable in the high-temperature sintering environment, ensuring reliable support and fixation for the ceramic blank.

[0018] 3. The adjustable support mechanism can adapt to ceramic blanks of different heights, and the auxiliary fixing components and clamping components work together to clamp and fix ceramic blanks of different shapes and sizes. There is no need to frequently change different specifications of brackets, which reduces production costs and improves the convenience and efficiency of production operations. The spherical protrusions disperse the support points between the bracket and the ceramic blank, avoiding local stress concentration. The spherical surface design reduces the contact area between the bracket and the blank, thereby reducing the risk of the bracket sticking to the ceramic blank or contaminating the surface of the blank.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments. Example 1

[0029] Reference Figure 1-5This is the first embodiment of the present invention, which discloses a deformation-resistant ceramic blank sintering support, comprising: a base 1, with support columns 2 fixedly connected to the four corners of the top of the base 1, a support plate 3 provided in the middle of the support columns 2, a plurality of ventilation holes 302 evenly opened on the surface of the support plate 3, auxiliary fixing components 4 provided on both sides of the top of the support plate 3, the auxiliary fixing components 4 including a slide rail 401, a slide rod 405 fixedly connected to the middle of the slide rail 401, a second slider 403 slidably connected to the surface of the slide rod 405, a spring 406 sleeved on the surface of the slide rod 405, a clamping component 6 provided at the top of the second slider 403, and a support mechanism 5 provided between the support plate 3 and the base 1.

[0030] With the adjustable support mechanism 5, the height of the ceramic blank can be flexibly adjusted during use to ensure that the blank is in a suitable support position. With the auxiliary fixing component 4 and the clamping component 6, the ceramic blank is clamped and fixed by the clamping block 602 during use, which limits the displacement and deformation trend of the blank during the sintering process. At the same time, the vent holes 302 on the support plate 3 help the gas to escape, so that the blank is heated evenly, thereby effectively preventing the ceramic blank from deforming during the sintering process and improving product quality and yield. Example 2

[0031] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0032] High-temperature resistant anti-slip pads 101 are fixedly connected to the four corners of the bottom of the base 1. A sliding groove 201 is opened in the middle of the support column 2. A first slider 301 is fixedly connected to the four corners of the support plate 3. The first slider 301 is slidably connected inside the sliding groove 201.

[0033] With the support column 2 and the high-temperature resistant anti-slip pad 101, the support column 2 is made of high-temperature resistant and high-strength ceramic material, and the four corners of the bottom of the base 1 are equipped with high-temperature resistant anti-slip pads 101. The overall structure can remain stable in the high-temperature sintering environment, ensuring reliable support and fixation for the ceramic blank.

[0034] Limiting grooves 402 are provided on both sides of the slide rail 401. Limiting blocks 404 are fixedly connected to both sides of the second slider 403. The limiting blocks 404 are slidably connected inside the limiting grooves 402. The second slider 403 is slidably connected to the middle of the slide rail 401. The spring 406 is made of high-temperature resistant silicon nitride material. One end of the spring 406 abuts against one side of the second slider 403, and the other end of the spring 406 abuts against one end of the slide rail 401.

[0035] A groove 102 is provided in the middle of the bottom end of the base 1. The support mechanism 5 includes a threaded rod 501, which is rotatably connected to the middle of the base 1. A knob 502 is fixedly connected to the bottom end of the threaded rod 501. The knob 502 is located inside the groove 102. A threaded sleeve 503 is threadedly connected to the top end of the threaded rod 501. The top end of the threaded sleeve 503 is fixedly connected to the middle of the bottom end of the support plate 3.

[0036] The clamping assembly 6 includes an L-shaped support rod 601. The bottom end of the L-shaped support rod 601 is fixedly connected to the top end of the second slider 403. The other end of the L-shaped support rod 601 is rotatably connected to a clamping block 602. The clamping block 602 is arc-shaped. A protective pad 603 is fixedly connected to the surface of the clamping block 602. Several spherical protrusions 604 are evenly distributed on the surface of the protective pad 603.

[0037] The adjustable support mechanism 5 can adapt to ceramic blanks of different heights, and the auxiliary fixing component 4 and the clamping component 6 work together to clamp and fix ceramic blanks of different shapes and sizes. There is no need to frequently change different specifications of brackets, which reduces production costs and improves the convenience and efficiency of production operations. The spherical protrusion 604 disperses the support points between the bracket and the ceramic blank, avoiding local stress concentration. The spherical design of the surface reduces the contact area between the bracket and the blank, thereby reducing the risk of the bracket sticking to the ceramic blank or contaminating the surface of the blank.

[0038] The remaining structure is the same as that in Example 1.

[0039] The workflow of this utility model is as follows:

[0040] First, based on the height of the ceramic blank, rotate knob 502. Through the interaction between threaded rod 501 and threaded sleeve 503, the support plate 3 moves up and down along the slide groove 201 of support column 2, adjusting the support plate 3 to a suitable height. Then, place the ceramic blank on the support plate 3 and clamp it in place using clamping block 602. The adjustable support mechanism 5 can adapt to ceramic blanks of different heights. The auxiliary fixing component 4 and clamping component 6 work together to clamp and fix ceramic blanks of different shapes and sizes, eliminating the need to frequently change brackets of different specifications, reducing production costs, and improving the convenience and efficiency of production operations.

[0041] Secondly, the sintering support with the fixed ceramic blank is placed in the sintering furnace for sintering. With the setting of support column 2 and high temperature resistant anti-slip pad 101, the support column 2 is made of high temperature resistant and high strength ceramic material, and the four corners of the bottom of the base 1 are equipped with high temperature resistant anti-slip pad 101. The overall structure can remain stable in the high temperature sintering environment, ensuring reliable support and fixation of the ceramic blank. During the sintering process, the vent holes 302 on the support plate 3 can allow gas to be discharged smoothly, ensuring that the ceramic blank is heated evenly. With the adjustable support mechanism 5, it can be flexibly adjusted according to the height of the ceramic blank to ensure that the blank is in a suitable support position. With the setting of auxiliary fixing component 4 and clamping component 6, the ceramic blank is clamped and fixed by clamping block 602 during use, limiting the displacement and deformation trend of the blank during the sintering process. At the same time, the vent holes 302 on the support plate 3 help gas to be discharged, making the blank heated evenly, thereby effectively preventing the ceramic blank from deforming during the sintering process and improving product quality and yield.

[0042] Finally, after sintering is completed, the sintering support is removed from the sintering furnace, and the ceramic blank is removed. The spherical protrusions 604 disperse the support points between the support and the ceramic blank, avoiding local stress concentration. The spherical design of the surface reduces the contact area between the support and the blank, thereby reducing the risk of the support sticking to the ceramic blank or contaminating the surface of the blank.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
