Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0025] Such as figure 1 , 2 As shown, the high-performance waterjet ceramic sand pipe of the present invention includes: a pipe body 1, one end 11 of the pipe body is a tapered end, and the other end 12 has an inner tapered structure. Wherein, the pipe body 1 uses pressureless sintered silicon carbide, pressureless sintered boron carbide or pressureless sintered titanium boride pellets as raw materials, and is pressed and formed by cold isostatic pressing, and then the ceramic is completed by pressureless sintering. After dense ...

Abstract

The invention provides a high-performance water jet scalpel ceramic sand tube and a production method thereof. The high-performance water jet scalpel ceramic sand tube comprises a tube body, and one end of the tube body is a tapered end. The production method comprise the following steps: performing compaction molding on a raw material pressureless-sintered silicon carbide, pressureless-sintered boron carbide or pressureless-sintered titanium boride granules by a cold isostatic pressing molding process, performing ceramic compact sintering through a pressureless sintering process, performing cooling to obtain a ceramic blank, and performing ground finishing on the ceramic blank to obtain the finished ceramic sand tube. The silicon carbide, boron carbide, titanium boride or other high-hardness and high-wear resistance ceramic materials can be processed to develop the high-hardness, good-wear resistance and long-service life wear-resistant sand tube for a water jet scalpel, so the cutting efficiency of the water jet scalpel is further improved.

Description

technical field [0001] The invention relates to a water jet sand tube, in particular to a high-performance water jet ceramic sand tube and a preparation method thereof. Background technique [0002] Water cutting equipment (also known as water jet) is a widely used high-pressure water jet cutting equipment. Water is used as the working medium, and the working pressure can reach 50-800MPa. Adding abrasives such as pomegranate sand and carborundum to the high-pressure water to assist cutting can significantly improve the water flow. The cutting speed and cutting thickness of the knife have been widely used in many industries such as ceramics, stone, glass, metal, and composite materials. [0003] Sand pipe (also known as sand mixing pipe or sandblasting pipe) is an essential key component in water jets. It can withstand the severe wear of high-pressure and high-speed cutting media. It is the most important consumable in water jet equipment and has a large market demand. The s...
