Description

Technical Field

[0001] This utility model belongs to the field of magnetic tile sintering technology, specifically relating to a sintering support plate for magnetic tile sintering. Background Technology

[0002] The sintering plate is a tool used to support the magnetic tiles during the sintering process. The sintering plate has excellent characteristics such as high working temperature, good thermal shock stability, small expansion coefficient, high bending strength, excellent high temperature load softening performance, and long service life.

[0003] Currently, when the applicant's original firing plates are stacked, the upper and lower firing plates are mostly spaced apart by spacers. When moving the firing plates, they are prone to sliding and misalignment, which can cause the upper firing plate to tilt or even collapse. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a sintering plate for magnetic tile sintering to solve the problems mentioned in the background art. The sintering plate for magnetic tile sintering provided by this invention has the characteristic of good connection stability between the upper and lower sintering plates.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sintering plate for magnetic tile sintering, comprising a sintering plate body, slots respectively provided at the four corners above the sintering plate body, and inserts corresponding to the slots connected at the four corners below the sintering plate body, with a first inclined surface provided on each of the four sides at the lower end of the inserts, and a second inclined surface corresponding to the first inclined surface provided inside the slots.

[0006] Furthermore, the firing plate body is made of alumina or silicon carbide.

[0007] To increase the depth of the slot and thus ensure the stability of the insert after it is inserted into the slot, extension sleeves corresponding to the slots are connected to the four corners below the main body of the firing plate. The insert is connected to the lower part of the extension sleeve, and the slot extends into the interior of the extension sleeve.

[0008] In order to make the inner arc surface of the magnetic tile equidistant from the upper surface of the firing plate body, thereby making the heating of the magnetic tile more uniform, ensuring the consistency of the magnetic properties of the magnetic tile, and improving the product yield, several equally spaced arc-shaped protrusions are further provided on the upper part of the firing plate body.

[0009] In order to make the outer arc surface of the magnetic tile equidistant from the lower surface of the upper support plate body, thereby making the heating of the magnetic tile more uniform, ensuring the consistency of the magnetic properties of the magnetic tile, and improving the product yield, the lower part of the support plate body is provided with an arc groove corresponding to the arc protrusion.

[0010] In order to limit and position the placement of the magnetic tiles and ensure the uniformity of their arrangement, thereby ensuring uniform heating, a limiting rib is further provided between two adjacent arc-shaped protrusions.

[0011] To ensure that both the upper and lower surfaces of the firing plate can reflect heat and thus guarantee the heating temperature of the magnetic tile during sintering, a reflective layer is further provided on both the upper and lower surfaces of the firing plate. The reflective layer is a polished layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model achieves the stacking of two firing plate bodies by inserting a plug into a slot. Under the gravity of the firing plate body and the magnetic tile, the stability of the stacked firing plate bodies is ensured by the cooperation of the first inclined surface and the second inclined surface, avoiding shaking or even misalignment when moving the firing plate body.

[0014] 2. This utility model increases the depth of the slot by setting an extension sleeve, thereby ensuring the stability of the plug after it is inserted into the slot.

[0015] 3. The upper part of the firing plate body of this utility model is provided with several equally spaced arc-shaped protrusions, so that the inner arc surface of the magnetic tile is equidistant from the upper surface of the firing plate body. The lower part of the firing plate body is provided with arc-shaped grooves corresponding to the arc-shaped protrusions, so that the outer arc surface of the magnetic tile is equidistant from the lower surface of the upper firing plate body. This makes the heating of the magnetic tile more uniform, ensures the consistency of the magnetic properties of the magnetic tile, and improves the product yield.

[0016] 4. The present invention provides a limiting rib between two adjacent arc-shaped protrusions to limit and position the placement of the magnetic tiles, ensuring the uniformity of the magnetic tile arrangement and thus ensuring the uniformity of heating.

[0017] 5. The upper and lower surfaces of the firing plate body of this utility model are provided with reflective layers, so that the upper and lower surfaces of the firing plate body can reflect heat energy, thereby ensuring the heating temperature of the magnetic tile during sintering.

[0026] By adopting the above technical solutions, alumina is used for sintering ferrite magnetic tiles, and silicon carbide is used for sintering neodymium iron boron magnetic tiles.

[0027] Example 2

[0028] The difference between this embodiment and embodiment 1 is that, specifically, the four corners below the bearing plate body 1 are connected to extension sleeves 8 corresponding to slots 7, the insert block 2 is connected below the extension sleeve 8, and the slot 7 extends into the interior of the extension sleeve 8.

[0029] By adopting the above technical solution, the depth of the slot 7 is increased by extending the sleeve 8, thereby ensuring the stability of the insert 2 after it is inserted into the slot 7.

[0032] By adopting the above technical solution, the inner arc surface of the magnetic tile is equidistant from the upper surface of the bearing plate body 1, thereby making the heating of the magnetic tile more uniform, ensuring the consistency of the magnetic properties of the magnetic tile, and improving the product yield.

[0035] Example 4

[0036] The difference between this embodiment and embodiment 1 is that a limiting rib 4 is provided between two adjacent arc-shaped protrusions 6.

[0037] By adopting the above technical solution, the placement and positioning of the magnetic tiles are limited, ensuring the uniformity of the magnetic tile arrangement, thereby ensuring the uniformity of heating.

[0038] Example 5

[0039] The difference between this embodiment and embodiment 1 is that: specifically, a reflective layer is provided on both the upper and lower surfaces of the bearing plate body 1, and the reflective layer is a polished layer formed by polishing.

[0041] In summary, this invention achieves the stacking of two firing plate bodies 1 by inserting the insert block 2 into the slot 7. Under the gravity of the firing plate body 1 and the magnetic tile, the stability of the stacked firing plate body 1 is ensured by the cooperation of the first inclined surface 3 and the second inclined surface, preventing shaking or even misalignment when the firing plate body 1 is moved. This invention increases the depth of the slot 7 by setting the extension sleeve 8, thereby ensuring the stability of the insert block 2 after being inserted into the slot 7. The upper part of the firing plate body 1 of this invention is provided with several equally spaced arc-shaped protrusions 6, so that the inner arc surface of the magnetic tile is equidistant from the upper surface of the firing plate body 1. The lower part of the firing plate body 1 is provided with arc-shaped grooves 5 corresponding to the arc-shaped protrusions 6, so that the outer arc surface of the magnetic tile is equidistant from the lower surface of the upper firing plate body 1, thereby making the heating of the magnetic tile more uniform, ensuring the consistency of the magnetic properties of the magnetic tile, and improving the product yield. This invention features a limiting rib 4 between two adjacent arc-shaped protrusions 6, used to limit and position the placement of the magnetic tiles, ensuring the uniformity of the magnetic tile arrangement and thus ensuring uniform heating. The upper and lower surfaces of the firing plate body 1 are both provided with reflective layers, allowing both surfaces to reflect heat energy, thereby ensuring the heating temperature of the magnetic tiles during sintering.
