Ceramic thread processing tool and ceramic thread processing method

Abstract

The invention discloses a ceramic thread processing tool, comprising a body, wherein the body is formed in an integrated way; the body comprises a rodlike fixing section; one end of the fixing section is provided with a working section of which the diameter is smaller than that of the fixing section; a toothlike bump is annularly arranged towards the outer side on the periphery of the tail end of the working section; the top part of the toothlike bump is provided with a round angle; the root part of the lower end of the toothlike bump is connected with the bottom face of the working section; diamond sand grains are attached to the surface of the toothlike bump. The invention also discloses a ceramic thread processing method. The tool provided by the invention is igneous in design, rational in structure, convenient to produce and manufacture, lower in manufacturing cost, and convenient to use; by applying the tool, threads can be directly processed and formed in a ceramic product, so that a metal piece is not used, and the use of the metal piece is reduced; the formation of black spots, on the ceramic product, of metal dust is avoided; the pollution, caused by the use of the metal piece in a strong acid environment or a strong base environment, to the ceramic product is avoided.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a ceramic thread processing tool and a ceramic thread processing method. Background technique [0002] At present, when ceramic products are threaded, generally all are punched a straight hole slightly larger than the threaded hole on the ceramic product, and then the metal parts tapped in advance are embedded into the straight hole to form. This process is widely used because of its simplicity and difficulty in processing threads on ceramic products. However, during assembly, if the pre-tightening force of the threaded connection is too large, it is easy to cause the metal parts to fall off, and it is easy for the metal powder to embed into the interior of the ceramic during the inlaying of the metal parts, resulting in black spots on the ceramic products. Spots are more difficult to clean, making ceramic products scrapped and causing unnecessary losses. [0003] In additi...

However, during assembly, if the pre-tightening force of the threaded connection is too large, it is easy to cause the metal parts to fall off, and it is easy for the metal powder to embed into the interior of the ceramic during the inlaying of the metal parts, resulting in black spots on the ceramic products. Spots are more difficult to clean, making ceramic products scrapped and causing unnecessary losses

[0003] In addition, when the product is used in a relatively harsh environment (such as strong corrosion), metal parts are also prone to wear and tear
