Ceramic valve ball processing device with a hole in the center

Abstract

The invention discloses a method for machining a ceramic valve ball with a hole in the center. The method includes the following steps of firstly, pressing powder and machining a green body, wherein the powder is pressed into the valve ball green body with the hole in the center, and primary machining is conducted on the outer surface of the valve ball green body; secondly, conducting sintering, wherein the valve ball green body is arranged in a furnace to be sintered so that a ceramic sintering briquette ball can be formed; thirdly, grinding an inner hole, wherein the center hole is ground so that the size of the center hole can meet the design requirement; fourthly, conducting cutting according to the length, wherein the two ends, provided with the center hole, of the ceramic sintering briquette ball so that the length of the ceramic sintering briquette ball can meet the design requirement of the ceramic valve ball; fifthly, conducting surface machining, wherein the ceramic sintering briquette ball is fixed to a ceramic valve ball machining device through a fixing device, the outer circle is roughly ground at first, the spherical face fine grinding and polishing are conducted, and the machining process of the ceramic valve ball is completed. The invention further discloses the ceramic valve ball machining device. By means of the method, the surface machining of the ziconia ceramic valve ball can be efficiently conducted, and the spherical face machining quality is stable and reliable.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a ceramic valve ball processing device with a hole in the center. Background technique [0002] Ceramics are various products made of natural clay and various natural minerals as the main raw materials through crushing, kneading, molding and calcination. In the past, people called ceramics made of clay and fired at high temperature in special kilns. Ceramics is the general term for pottery and porcelain. [0003] With the development of society, ceramic products are becoming more and more popular in both industry and life. Zirconia ceramics have excellent properties such as high strength, high stiffness, high hardness, high specific gravity, high wear resistance, acid and alkali resistance, corrosion resistance, good insulation, non-conductivity and pollution-free. The preferred material for equipment and other products has been widely used in the fields of petrochemical, e...

Problems solved by technology

However, the hardness of zirconia ceramic balls is high, second only to diamond, which makes the processing of zirconia balls very difficult, the processing cycle is long, and the control of product size and precision is difficult.

Since the processing quality of the surface of zirconia ceramic balls and the precision after processing have an important impact on the service life of the product, the traditional processing technology is to process the surface of zirconia ceramic balls through strip-shaped sand bars, but this processing method has relatively Many defects, the amount of feed cannot be large, the feed speed is slow, and the cutting force is not high, so the efficiency of surface processing is not high, time-consuming and labor-intensive, and the spherical roughness after processing is difficult to meet the technical standard
