Embodiment 1

[0045] Such as figure 1 As shown, it is a structural schematic diagram of a ceramic green body connecting device according to an embodiment of the present invention, which is used for connecting two square flat ceramic green bodies of the same size and shape, including a lower support part 1 for placing a square flat ceramic green body, The lower supporting part 1 is a square plate structure, and its size is larger than that of the square plate ceramic green body.

[0046] An upper support part 2 having the same size as the lower support part is provided above the lower support part 1, and the lower support part 1 and the upper support part 2 overlap in plan view angle, and the ceramic green body after docking is placed Between the lower supporting part 1 and the upper supporting part 2 .

[0047] The four corners of the lower support part 1 are respectively fixedly connected with screw rods 3, and the corresponding positions of the upper support part 2 are respectively provi...

Embodiment 2

[0060] Such as figure 2 As shown, it is a structural schematic diagram of a ceramic green body connecting device according to another embodiment of the present invention, which is used for connecting flat ceramic green bodies with central circular holes of the same size, including a lower support part for placing flat ceramic green bodies 1. The lower supporting part 1 is a circular plate structure.

[0061] A screw rod 3 is fixedly connected to the center of the lower supporting part 1, and a stopper 6 is provided on the screw rod 3 to control the butt joint accuracy of two flat ceramic green bodies, so as to avoid the gap between the two flat ceramic green bodies after docking. sliding relative to each other.

[0062] An upper support part 2 is also provided on the screw rod 3, and the butted ceramic green body is placed between the lower support part 1 and the upper support part 2; a spring 4 and a spring 4 are also provided on the screw rod 3. Nut 5, the spring 4 is loc...

Abstract

The invention provides a connecting device for ceramic biscuits. The device comprises a lower supporting part and an upper supporting part which are used for placing plate ceramic biscuits. The buttedceramic biscuits are arranged between the lower supporting part and the upper supporting part. The device further comprises an elastic force application structure and a limiting part, wherein the limiting part is used for improving the butt joint precision of the plate ceramic biscuits and avoiding relative sliding in the heating or force application process, the elastic force application structure ensures the uniformity of force application, and position movement caused by linear expansion mismatching or thickness change of a connecting layer in the heating process is compensated. Accordingto the connecting device and a corresponding connecting method for the ceramic biscuits, the technical problem that the connecting effect of the ceramic biscuits is poor due to the fact that the forceapplication or butt joint process is not ideal in the connecting process is effectively solved, and the connecting effect is remarkable particularly for the connecting process of the ceramic biscuitsneeding continuous force application and accompanied by heating.

Description

technical field [0001] The invention relates to the technical field of ceramic material preparation, in particular to a ceramic biscuit connecting device and method. Background technique [0002] With its unique performance advantages, ceramic materials are widely used in many fields such as people's livelihood and national defense. Due to the limitations of ceramic preparation technology and the customization requirements of final products, in the production process of some ceramic products, it is necessary to connect green bodies, that is, to connect several ceramic green bodies into a whole. [0003] In the prior art, taking reaction sintered SiC ceramics as an example, in order to ensure the consistency of the connection layer and the base material and realize the homogeneous connection of the final state of the ceramics, most of the SiC ceramic green bodies are connected with a binder, and then through the reaction The sintering process realizes that the microstructure...
