Description

Technical Field

[0001] The invention relates to the field of grinding equipment, and more specifically, to a burr grinding equipment for graphite tubes produced by diamond composite sheets. Background Art

[0002] Diamond composite drill bits are one-piece drill bits that use diamond composites as cutting edges. They have high strength, high wear resistance and impact resistance. This composite piece is usually composed of diamond particles and a metal matrix (such as cobalt-based, iron-based or nickel-based alloys). The diamond particles provide extremely high hardness and wear resistance, while the metal matrix provides good toughness and thermal conductivity. When producing this diamond composite piece, high temperature and high pressure technology, such as hot pressing or fire forming technology, is usually required.

[0003] Graphite tubes play an important role in the production process of diamond composite sheets, mainly as a device or auxiliary material for heating, pressurizing and carrying materials; graphite has good high-temperature stability and thermal conductivity, and can remain stable in high-temperature environments. Therefore, graphite tubes are often used in the high-temperature sintering process in the production of diamond composite sheets, especially when combining diamond particles with metal substrates under high pressure and high temperature, the role of graphite tubes is to provide a heating environment; the manufacture of diamond composite sheets usually requires high temperature and high pressure conditions, similar to the process of diamond formation in nature. Graphite materials can not only withstand high temperatures, but can also be used as a carrier material in some equipment to help contain powder or particles under high pressure and ensure the uniform fusion of diamond and metal substrates.

[0004] A graphite tube with a composite sheet accommodating hole inside is made by a press, and then a grinding device is needed to grind the end face of the graphite tube to achieve the deburring effect. Although the existing large-scale automated grinding equipment is technologically mature, its high procurement, debugging, maintenance and overhaul costs are unacceptable to small-batch manufacturers, and some low-cost grinding equipment has low adaptability, stability and efficiency.

[0005] In order to solve the above problems, the present application proposes a burr grinding device for producing graphite tubes from diamond composite sheets. Summary of the invention
