Description

Technical Field

[0001] The utility model relates to the field of diamond composite sheets, in particular to a three-pointed octahedral diamond composite sheet. Background Art

[0002] Diamond composite sheet is a composite material composed of diamond and cemented carbide matrix. It has the characteristics of high hardness and good wear resistance. It is widely used in industries such as oil drilling, geological exploration, coal drilling drill bits and mechanical processing tools.

[0003] Publication No. CN213478232U discloses a diamond composite sheet and a drill bit. The diamond composite sheet includes a cemented carbide substrate and a diamond layer. One side of the diamond layer has a plurality of blade teeth. The blade teeth are arranged at intervals along the circumference of the diamond layer. A chip groove is formed between adjacent blade teeth. One end of the chip groove is close to the center of the working end face, and the other end of the chip groove is far away from the center of the working end face. A protrusion is arranged at the end of the chip groove close to the center of the working end face. When the blade teeth cut the rock formation, the rock chips can collide with the protrusion when moving along the chip groove. The protrusion and the large rock chips can break the large rock chips, which is convenient for the discharge of the rock chips. Since the utility model has a plurality of protrusions and the protrusions are arranged at intervals, the intervals between the protrusions can allow the rock chips to pass through, thereby improving the drilling efficiency of the drill bit, solving the technical problem that the boss of the current diamond composite sheet has a large influence on the chip removal, resulting in low chip removal efficiency. However, the patent still has the following problems in actual use:

[0004] The diamond composite sheet achieves the effect of promoting rock chip removal by providing chip removal grooves and protrusions. However, since the structure of the diamond composite sheet with blade teeth is relatively smooth when in use, the diamond composite sheet is prone to slipping on the smooth rock surface, resulting in low excavation efficiency of the diamond composite sheet. In addition, when installing the diamond composite sheet, it is difficult to quickly locate the position of the blade teeth on one side of the diamond composite sheet on the drill bit, resulting in the diamond composite sheet being prone to falling off during welding, thereby resulting in poor practicality of the diamond composite sheet.

[0005] A tricuspid octahedral diamond composite sheet is proposed to solve the above problems. Utility Model Content
