Description

Technical Field

[0001] The utility model relates to an alumina sintering support block. Background Art

[0002] At present, ceramic products are widely used in various fields due to their unique flexural strength, high-voltage electrical insulation, thermal shock resistance, low loss and good chemical stability. Among them, ceramic tubes, ceramic rods or ceramic columns are widely used in electronic precision instruments. In the production process of ceramic tubes, ceramic rods or ceramic columns, the clay has no strength after drying and cannot be formed into products. Therefore, high-temperature sintering is required to solidify and shape them. The existing technology usually places the ceramic body on a firing plate, and then sends the firing plate with the ceramic body into the kiln to sinter and solidify the ceramic product body. The firing plate is an important tool in the production process of ceramic products.

[0003] The existing technology has firing support blocks designed for firing tubular or rod-shaped products, but there are no firing support blocks that are specifically designed to be deformed and adjusted according to the specifications of circular ring-shaped products. Therefore, the specifications and sizes of the existing firing support blocks are fixed and cannot be adaptively changed according to the specifications of the circular ring-shaped products. The applicability is poor, resulting in the need to repeatedly replace the firing support blocks when sintering and producing circular ring-shaped products of different specifications. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an alumina sintering support block.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] An alumina burning support block includes a support block body, movable pins inserted at both ends of the support block body for connecting two adjacent support block bodies, two parallel semicircular shallow grooves for product placement are provided at the upper end of the support block body, a semicircular deep groove for product placement is provided at the center of the lower end of the support block body, a movable through hole is provided at the position of the support block body corresponding to the insertion of the movable pin, and embedding holes that pass through and connect the movable through holes are provided at the center of both sides of the support block body. The support block body is also provided with a fixing column that is embedded in the embedding hole and extends into the movable through hole to limit the detachment of the movable pin.

[0007] Preferably, the support block body is arranged in a W shape.

[0008] Preferably, when the semicircular deep groove faces upward, the support block body is arranged in an M shape, and auxiliary sleeves are arranged on both sides of the semicircular deep groove.

[0009] Furthermore, inclined holes for embedding auxiliary sleeves are provided on both sides of the interior of the semicircular deep groove.

[0010] Furthermore, the auxiliary sleeve includes an arc-shaped ceramic auxiliary plate and obliquely inserted columns integrally formed at both ends below the ceramic auxiliary plate.

[0011] Preferably, the movable latch includes a movable latch body and a limiting groove provided on one side of the movable latch body.

[0012] The beneficial effects of the present invention are as follows: when the support block body is placed in a W shape, the annular product can be placed upright in a semicircular shallow groove for firing; and when the support block body is placed in an M shape, auxiliary sleeves of different specifications can be replaced to place annular products of different specifications. In addition, several support block bodies can be spliced ​​into products of different specifications through movable pins, so that the corresponding number of support block bodies can be selected for assembly according to the number of annular products.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0020] Example 1

[0021] like Figure 1-4As shown, a W-shaped support block for the production of alumina support plates includes a support block body 1, movable pins 2 inserted at both ends of the support block body 1 for connecting two adjacent support block bodies 1, the upper end of the support block body 1 is provided with two parallel semicircular shallow grooves 11 for product placement, the lower end of the support block body 1 is provided with a semicircular deep groove 12 for product placement, the support block body 1 is provided with a movable through hole 13 at the position corresponding to the insertion of the movable pin 2, and the support block body 1 is provided with an embedding hole 14 that passes through and connects to the movable through hole 13 at the center of both sides. The support block body 1 is also provided with a fixing column 15 that is embedded in the embedding hole 14 and extends into the movable through hole 13 to limit the detachment of the movable pin 2.

[0022] The support block body 1 is arranged in a W shape. Specifically, it can place products with a smaller radius for sintering through two parallel semicircular shallow grooves 11.

[0023] The movable latch 2 includes a movable latch body 21 and a limiting groove 22 provided on one side of the movable latch body 21. Specifically, the movable latch body 21 is first inserted into the support block body 1 through the movable through hole 13, and then the fixed column 15 is inserted into the support block body 1 through the embedding hole 14. The bottom of the fixed column 15 extends into the movable through hole 13 and is stuck in the limiting groove 22. At this time, the movable latch body 21 can move in the movable through hole 13, but is restricted by the fixed column 15 and cannot be separated from the support block body 1.

[0024] Example 2

[0025] like Figure 5-6 As shown, the difference between this embodiment and embodiment 1 is that when the semicircular deep groove 12 faces upward, the support block body 1 is arranged in an M shape, and auxiliary sleeves 3 are arranged on both sides of the semicircular deep groove 12. The semicircular deep groove 12 has inclined holes 121 on both sides for embedding the auxiliary sleeves 3.

[0026] The auxiliary sleeve 3 includes an arc-shaped ceramic auxiliary plate 31 and oblique insertion columns 32 integrally formed at both ends below the ceramic auxiliary plate 31. Specifically, the oblique insertion columns 32 can cooperate with the oblique holes 121, thereby being fixedly installed in the semicircular deep groove 12. Specifically, by replacing auxiliary sleeves 3 of different specifications, it can adapt to products of different radii.

[0027] It should be further explained that, regardless of whether the support block body 1 is arranged in a W shape or in an M shape after being flipped over, when several support block bodies 1 are placed end to end, the assembly can be completed by pushing the movable pin 2 so that it is embedded in the movable through hole 13 of the connected support block bodies 1.

[0028] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
