Background technique

Claim polycrystalline diamond thin layer to plycrystalline diamond by the composite material that high temperature and pressure attachment is bonded on hard alloy substrate Diamond compact, referred to as (PDC).The hardness and wearability of the existing diamond of composite polycrystal-diamond have and close with hard Intensity, toughness and the good weldability of gold, are a kind of cutting tool materials of brilliance, have been widely used in stone The numerous areas such as oil, coal, geological drilling, machining.

Currently, leading to the increase of drilling depth with the development of probing production industry and the increasingly reduction of production of resources, being Adapt to more complicated ground environment；Conventional flat-face composite sheet reduces under bad ground environment into tooth efficiency, And it is easy phenomena such as collapsing tooth, accordingly, it is desirable to provide a kind of be both able to satisfy bad ground and to have met the plycrystalline diamond Buddha's warrior attendant of drilling efficiency Stone composite sheet.

Therefore, it is necessary to a kind of NEW TYPE OF COMPOSITE piece be provided, to solve defect existing in the prior art.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of NEW TYPE OF COMPOSITE piece.

The utility model provides a kind of NEW TYPE OF COMPOSITE piece, including mutually compound diamond composite layer 1, hard alloy pedestal 2,1 upper surface of diamond composite layer is convex surface, and the unilateral angle with horizontal plane on the convex surface is greater than 1 °, diamond composite layer 1 Lower end surface is concave surface；2 upper surface of hard alloy pedestal is mutually agreed with 1 lower end surface of diamond composite layer, i.e. carbide matrix Fitting 1 lower end surface of the diamond composite layer setting of 2 upper surfaces of seat.

Preferably, the unilateral angle with horizontal plane a of 1 upper surface of diamond composite layer is 35 °~45 °, thus Sufficiently conducive to the drillability of ridge, toughness.

Further embodiment is that the diamond composite layer 1 is ridge.

The lower end surface of the diamond composite layer 1 is convexly equipped with several composite layer protrusions 11, on the hard alloy pedestal 2 End face is convexly equipped with several pedestal layer protrusions 21；Composite layer protrusion 11 is meshed fixation with pedestal layer protrusion 21.It needs herein It is noted that projection can be welding, be fixedly connected, it is also possible to be wholely set, those skilled in the art can be in conjunction with this The setting relationship between protrusion and each layer is obtained known in field.

Further, the diamond composite layer 1 is made of polycrystalline diamond.

Further embodiment is that the top of the NEW TYPE OF COMPOSITE piece offers cutting channel 3 to bottom end along its center, is opened up Cutting channel 3 efficiently uses ridge plycrystalline diamond composite sheet, cuts composite sheet along radius in setting, adjusts angle when passing through cutting Degree meets the balance of welding stress point.

Compared with the relevant technologies, the utility model has the following beneficial effects:

The utility model ridge structure half composite polycrystal-diamond: full wafer ridge polycrystalline diamond composite layer is raw At particularity structure and generate technique, tipping is not easy when being rock cutting；Hard alloy pedestal and diamond layer pass through protrusion Engagement, improves the force-bearing situation between hard alloy pedestal and diamond layer, and the outside highest point of ridge improves composite sheet Drilling efficiency cuts composite sheet along radius to efficiently use ridge plycrystalline diamond composite sheet, and it is full to adjust angle when passing through cutting The balance of foot welding stress point, makes half polycrystalline diamond layer be not easy tipping, improve drilling efficiency, extends service life.

Specific embodiment

Below in conjunction with drawings and embodiments, the utility model is described in further detail.

Fig. 1 is please referred to, the utility model of the utility model provides a kind of NEW TYPE OF COMPOSITE piece, including mutually compound Buddha's warrior attendant Stone composite layer 1, hard alloy pedestal 2,1 upper surface of diamond composite layer are convex surface, and unilateral side and the horizontal plane on the convex surface press from both sides Angle is greater than 1 °, and 1 lower end surface of diamond composite layer is concave surface；2 upper surface of hard alloy pedestal and 1 lower end of diamond composite layer Face is mutually agreed with, i.e. the setting of 2 upper surface of hard alloy pedestal fitting, 1 lower end surface of diamond composite layer.

As an embodiment of the present invention, referring to figure 4., in the present embodiment, the diamond is compound The unilateral angle with horizontal plane a of 1 upper surface of layer is 35 °~45 °, thus sufficiently conducive to the drillability of ridge, toughness.

Fig. 1 is please referred to, the diamond composite layer 1 is ridge.

The lower end surface of the diamond composite layer 1 is convexly equipped with several composite layer protrusions 11, referring to figure 2., 3, described hard 2 upper surface of matter alloy pedestal is convexly equipped with several pedestal layer protrusions 21；The composite layer protrusion 11 is meshed with pedestal layer protrusion 21 It is fixed.Herein it should be noted that projection can be welding, be fixedly connected, it is also possible to be wholely set, those skilled in the art Member can be in conjunction with the setting relationship known in this field obtained between protrusion and each layer.

The diamond composite layer 1 is made of polycrystalline diamond.

As another variant embodiment of the utility model, referring to figure 5., in the present embodiment, the NEW TYPE OF COMPOSITE The top of piece offers cutting channel 3 to bottom end along its center, opens up cutting channel 3 and efficiently uses ridge plycrystalline diamond composite sheet, Composite sheet is cut along radius when setting, passes through and adjusts the balance that angle meets welding stress point when cutting, make half plycrystalline diamond Diamond layer is not easy tipping, improves drilling efficiency, extends service life.
