Embodiment 1

[0010] A method for removing burrs from pressure-sensitive sheets. Firstly, the Φ2.8mm x Φ1.5mmx0.4mm ring-shaped pressure-sensitive element green body 1 formed by dry pressing is pre-fired at a temperature of 1100°C; The water and the pre-fired component body are put into the planetary grinding tank for grinding, and finally cleaned and dried. The mass ratio of grinding medium, water and green body is 40:18:3. The rotation speed of the planetary mill jar is 35 rpm, and the time is 5 minutes. The pre-burning time is 3 hours, and the grinding medium is made of ceramic powder after high-temperature pre-burning, ball milling, drying and sieving. The high-temperature pre-firing temperature of the grinding medium is 1250°C. The mesh number of the sieve is 120 mesh. The ceramic powder is the dry powder before the element green body is formed.

[0011] The product obtained by removing the green body burr 2 by the above method has a smooth and smooth appearance, no burr, and no pr...

Embodiment 2

[0013] A method for removing the burr of a ring-shaped pressure-sensitive thick sheet. Firstly, the Φ4.2mm x Φ2.8mm x0.7mm ring-shaped pressure-sensitive element body 1 formed by dry pressing is pre-fired at a temperature of 1000°C; Put the grinding medium, water and the pre-fired element body into the planetary grinding tank for grinding, and finally wash and dry. The mass ratio of the grinding medium, water and green body is 42:16:3. The rotation speed of the planetary mill jar is 35 rpm, and the time is 8 minutes. The pre-firing time is 3.5 hours, and the grinding medium is made of ceramic powder after high-temperature pre-firing, ball milling, drying and sieving. The high-temperature pre-firing temperature of the grinding medium is 1250°C. The mesh number of the sieve is 120 mesh. The ceramic powder is the dry powder before the element green body is formed.

[0014] The product obtained by removing the burrs of the green body by the above method has a smooth and flat a...

Embodiment 3

[0016] A method for removing the burrs of the cylindrical heat-sensitive element body. Firstly, the dry-pressed Φ3.7mm x 2.6mm cylindrical heat-sensitive element body 3 is pre-fired at a temperature of 900°C; , water and the pre-fired component blanks are put into a planetary mill tank for grinding, and finally cleaned and dried. The mass ratio of the grinding medium, water and green body is 45:18:3. The rotating speed of the planetary grinding jar is 30 rpm, and the time is 12 minutes. The pre-firing time is 5 hours, and the grinding medium is made of ceramic powder after high-temperature pre-firing, ball milling, drying and sieving. The high-temperature calcining temperature of the grinding medium is 1180°C. The mesh number of the sieve is 100 mesh. The ceramic powder is the dry powder before the element green body is formed.

[0017] The product obtained by removing the green body burr 2 by the above method has a smooth and flat appearance, no burr, and no product colla...

Abstract

The invention discloses a method for removing raw edges of an element blank body and an application thereof. The method comprises the following steps that: firstly, the element blank body after dry pressing and molding is subject to preburning treatment; a preburning temperature is between 700 and 1,100 DEG C; a grinding medium, water and a preburned element blank sheet are put into a planetary grinding tank for carrying out sheet grinding treatment; and finally the element blank sheet is cleaned and dried. The product produced by removing the raw edges by the method has smooth and flat appearance, no raw edges, no collapse and other poor phenomena. The method is used for removing the raw edges of the sensing element blank body, and the qualified rate of the appearance of the ground sensing element blank body reaches 99 percent above.

Description

technical field [0001] The invention relates to the technical field of component blank processing, in particular to a method for removing burrs from a sensitive component blank. Background technique [0002] The existing method for removing the green body of the element is: put the sintered ceramic body into a ball mill pot and add water for wet grinding, and use the friction between the ceramic bodies to remove the burrs or burrs. Rigid collision is used to achieve the purpose of removing burrs, and the ceramic body is brittle, which causes many problems such as chipping or fracture of the ceramic body. Alternatively, the surface of the sintered ceramic body can be ground flat by mechanical processing. This method is currently applicable to the production of larger ceramic bodies, and this method also has the phenomenon of edge chipping of the ceramic body. Or put the newly formed green body into the vibrating screen for vibration grinding, and use the friction between the...
