Abstract

The invention provides a diamond hard alloy composite tooth for the oil exploration and the mining, belongs to the technical field of a complex rock stratum and high hardness rock stratum cutting tool, particularly relates to cylindrical and sheet-shaped diamond embedded bodies for being embedded and filled in a cutting cutter head and aims to solve the problems of easiness for crushing, poor impact resistance, easiness for stripping of a composite layer and high requirement on the geological conditions. The diamond hard alloy composite tooth is mainly characterized in that the diamond embedded bodies are embedded in the surface of a hard alloy matrix of the cutter head, which participates in cutting; particularly, round tube embedded bodies are combined with the hard alloy matrix in a ring shape; and the cylindrical embedded bodies and polyhedral embedded bodies are combined with the hard alloy matrix in a point shape.

Description

The diamond hard alloy composite teeth is used in oil exploration and mining

Technical field

The invention belongs to complex formation, high rigidity rock stratum cutting means technical field, be specifically related to oil exploration and the diamond hard alloy composite teeth is used in mining.

Background technology

Technical development along with oil drilling, various mining industry and traffic tunnel are built has had requirements at the higher level to cut complex formation, the used cutting means cutter head in high rigidity rock stratum, and domestic this series products that can provide is to be main with carbide alloy basically; Proportion scale with carbide alloy changes its Cutting Performance, and pure hard-metal insert can not satisfy the requirement in market, and existing diamond hard alloy composite teeth exists big defective in structure aspects; Because the diamond composite bed is that face combines with hard alloy substrate; And the hardness of diamond composite bed is high, is prone to fragmentation, characteristics such as shock resistance difference; Cause composite bed to be prone to peel off; High to the geology conditional request, impact resistance is poor, and cost is higher.

Summary of the invention

The objective of the invention is to solve diamond composite bed that prior art exists and be prone to brokenly, the problem of shock resistance difference is employed in to inlay on the hard alloy substrate and fills the diamond composite bed and process composite teeth.

The present invention solves the problems of the technologies described above the technical scheme of taking to be:

The diamond hard alloy composite teeth is used in oil exploration and mining, is made up of cutter head hard alloy substrate and diamond insert body; It is characterized in that: mosaic gold hard rock mosaics on the surface that the participation of cutter head hard alloy substrate is cut.

Said cutter head hard alloy substrate is cylindric, and the surface of participating in cutting is columned end-cone side surface; Said diamond insert body inlay be filled in said columned end-cone side surface and top on.

Said diamond insert body be shaped as the pipe mosaics; Or be the cylinder mosaics; Or be the polyhedron mosaics.

Said diamond insert body is on cylindric cutter head hard alloy substrate, and plan view shape is respectively donut; Or roundlet on concentric circumference, equidistantly distributing; Or triangle or polygon on concentric circumference, equidistantly distributing.

Inlay the column that is shaped as of filling the diamond insert body on said cylindric cutter head hard alloy substrate top, this column termination is cone or spherical surface body.

Said cutter head hard alloy substrate is a sheet, and the surface of participating in cutting is the inclined-plane of sheet cutter head hard alloy substrate; Said diamond insert body is inlayed and is filled on the said inclined-plane; End mosaics on said sheet cutter head hard alloy substrate top be shaped as polyhedron.

The present invention compared with prior art has following beneficial effect:

1, the diamond insert body is embedded into hard alloy substrate, has effectively overcome the diamond composite bed and has been prone to fragmentation, the defective of shock resistance difference;

2, after carbide alloy work top layer was inlayed and filled the diamond insert body, because mosaics length is bigger than the diamond composite bed thickness of prior art, wear-resisting and difficult drop-off had effectively improved cutting strength and abrasion resistance, thereby has increased the service life.

The specific embodiment

Embodiment one:

Like Fig. 1, Fig. 2 and shown in Figure 3; The diamond hard alloy composite teeth is used in oil exploration and mining; The end-cone side surface of cylindric cutter head hard alloy substrate 1 and top on inlay and fill the diamond insert body, mosaics is divided into by shape: pipe mosaics 2, cylinder mosaics 4, polyhedron mosaics 5; Like Fig. 4, Fig. 5 and shown in Figure 6, its vertical view shape is respectively donut, at the roundlet that equidistantly distributes on the concentric circumference, the triangle that on concentric circumference, equidistantly distributes or polygon; The end mosaics 3 of said cylindric cutter head is shaped as column, and this column termination is a spherical surface body.

Embodiment two:

Like Fig. 9, Figure 10 and shown in Figure 11; On hard alloy substrate 1 inclined-plane 6 of sheet cutter head, inlay and fill the diamond insert body; The diamond insert body is divided into by shape: cylinder mosaics 4, polyhedron mosaics 5, the top end mosaics 3 of sheet cutter head is shaped as polyhedron.

Structural principle:

Like Figure 11 and shown in Figure 12, the planar diamond composite bed 7 of cylindric cutter head is that face combines with face with hard alloy substrate 1 in the prior art; The planar diamond composite bed 7 of sheet cutter head also is that face combines with face with hard alloy substrate 1 in the prior art; Like Fig. 1 and shown in Figure 4, the present invention is improved to pipe mosaics 2 with this combination and combines with hard alloy substrate 1 round; Be point-like with hard alloy substrate 1 and combine like Fig. 2, Fig. 3, Fig. 5 and cylinder mosaics 4, polyhedron mosaics 5 shown in Figure 6.
