Background
In the sintering molding process of the ceramic relay shell, an end face with a round table part in the shell is required to be placed on the top surface of the sagger for sintering, and as the round table part and the outer wall of the end face are not on the same plane, a gap still exists between the outer wall of the end face of the shell where the round table is positioned and the top surface of the sagger, which leads to the trend of outward expansion of the side face of the shell, and the defects of outward expansion, distortion of the end face and the like of the opening of the other end of the ceramic relay shell opposite to the end face in the sintering molding process seriously affect the product quality.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the prior art and providing a sintering device for sintering a ceramic relay shell, which is simple and practical, maintains the structural shape of a product, reduces the defect rate of the product and improves the quality of the product, and a sintering method using the sintering device.
In order to solve the technical problems, the technical scheme provided by the invention is as follows:
The sintering device for sintering the ceramic relay shell comprises a supporting part, wherein the supporting part is arranged between the end face of the shell and the top face of the sagger in a cushioning mode, and provides supporting force for the planes around the round table on the end face of the shell.
As a further improvement of the firing device:
The middle part of holding the portion is equipped with the clearance area that is used for dodging the round platform.
The depth of the clearance area is larger than the height of the round table extending out of the end face of the shell.
The sintering device further comprises a cushion seat, the supporting part is arranged at the top of the cushion seat, and the height of the supporting part extending out of the top surface of the cushion seat is larger than the height of the round table extending out of the end surface of the shell.
A sintering method using a sintering device for sintering a ceramic relay shell comprises the steps of placing the sintering device on the top surface of a sagger for sintering, then placing the end surface of a shell to be sintered with a round table downwards on the sintering device, adjusting the round table to be placed in a clearance area, enabling the planes around the round table on the end surface of the shell to be in contact with a supporting part, and sintering and forming.
Compared with the prior art, the invention has the advantages that:
The invention relates to a sintering device for sintering a ceramic relay shell, which comprises a supporting part, wherein the supporting part is arranged between the end surface of the shell and the top surface of a sagger in a cushioning way, and provides supporting force for planes around a round table on the end surface of the shell. After the ceramic relay shell uses the sintering device of the invention in the sintering process, as the planes around the round table are supported and have supporting force against the gravity borne by the side surfaces, the planes around the round table can not sink, so that the defect of distortion of the end surface of the shell is avoided, and the opening at the other end of the ceramic relay shell can not produce the expansion defect because of no side surface deformation, so that the morphological structure of the shell in the sintering process is effectively ensured, the defect rate of the sintered product is greatly reduced, and the product quality is optimized. The sintering method of the invention adopts the sintering device for sintering the ceramic relay shell, thus having the advantages as well, and the sintering quality can be optimized through simple arrangement.
Drawings
Fig. 1 is a schematic structural view of a firing device for sintering a ceramic relay case according to the present invention.
Legend description: 1. a holding part; 11. a void area is avoided; 2. a housing; 21. round bench; 3. a sagger; 4. and a cushion seat.
Detailed Description
The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments are shown, for the purpose of illustrating the invention, but the scope of the invention is not limited to the specific embodiments shown.
Examples:
As shown in fig. 1, the sintering device for sintering a ceramic relay shell of the embodiment comprises a supporting part 1, wherein the supporting part 1 is arranged between the end surface of the shell 2 and the top surface of the sagger 3 in a cushioning manner, and provides supporting force for the plane around the round table 21 on the end surface of the shell 2. After the ceramic relay shell 2 is used in the sintering process, as the planes around the round table 21 are supported and have supporting force against the gravity borne by the side surfaces, the planes around the round table 21 cannot sink, so that the end surface of the shell 2 is distorted, and the opening at the other end cannot produce outward expansion defects because of no side surface deformation, so that the morphological structure of the shell 2 in the sintering process is effectively ensured, the defect rate of the sintered product is greatly reduced, and the product quality is optimized.
In this embodiment, the middle part of the supporting part 1 is provided with a clearance area 11 for avoiding the round table 21, so as to avoid the supporting force being dispersed by the round table 21 due to the contact with the round table 21, and ensure the completely effective supporting of the plane around the round table 21.
In this embodiment, the depth of the clearance area 11 is greater than the height of the round table 21 extending out of the end face of the casing 2, and in this arrangement, the bottom of the round table 21 lacks supporting force, so that the casing 2 integrally generates a tendency of inward shrinkage, thereby counteracting the outward expansion tendency naturally generated in the sintering process of the top opening structure, and further solving the problem of poor dimension caused by outward expansion of the side face in the sintering process of the product.
In this embodiment, the sintering device further includes a cushion seat 4, the supporting portion 1 is disposed at the top of the cushion seat 4, the height of the supporting portion 1 extending out of the top surface of the cushion seat 4 is greater than the height of the circular table 21 extending out of the end surface of the casing 2, the cushion seat 4 and the supporting portion 1 isolate the casing 2 from the top surface of the sagger 3, so that not only a good structural directional supporting effect is achieved, but also defects such as pinholes caused by direct contact of the cushion seat 4 and the supporting portion 1 are avoided while uniform heat transfer is achieved.
In the sintering method using the sintering device for sintering the ceramic relay shell, the sintering device is placed on the top surface of the sintering sagger 3, then the end surface with the round table 21 in the shell 2 to be sintered faces downwards, the sintering device is placed on the sintering device, the round table 21 is adjusted to be placed in the clearance area 11, and the plane around the round table 21 on the end surface of the shell 2 is contacted with the supporting part 1 for sintering and forming. In the sintering process, the sintering device is simply arranged, so that the product quality and the qualification rate can be greatly improved, and the method is good in applicability, simple and convenient in steps and reliable in sintering finished product quality.
The above description is merely a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above examples. Modifications and variations which do not depart from the gist of the invention are intended to be within the scope of the invention.
