Description
Technical field
The utility model relates to a kind of drilling tool, is specifically related to a kind of processing that is used for various material with complex, like stone material, mixed earth, pitch, timber, cast iron, the drilling tool of glass etc.
Background technology
In the cut instrument, drill bit generally is divided into carbide drill and diamond bit, and carbide drill is mainly used in materials such as cutting cast iron, non-ferrous metal, plastics, chemical fibre, glass, stone material and steel; Diamond bit is mainly used in the various boring processing like stone material, pottery, xoncrete structure and bituminous texture of drilling.Along with difficult-to-machine material use increasingly extensive and universal; Its process technology has also been proposed more and more harsher requirement; Therefore, in order to realize the processing of material with complex, and improve the working (machining) efficiency of processing object; It is wide to be necessary to develop a kind of range of work, can realize the processing of material with complex, realize the drill for high-speed instrument of high efficiency, high stability, long-life processing simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of drilling tool, is not only applicable to the drilling of various high rigidity, high-strength material, and can realize the vertical boring and the transverse cuts of processing object.
For achieving the above object, the utility model provides following technical scheme:
A kind of drilling tool is characterized in that: comprise steel matrix 1, diamond abrasive grain 2, carbide bit 3, wherein the surface distributed of steel matrix 1 helicla flute 21, and its top is a v-shaped structure; Diamond abrasive grain 2 solderings are on the surface of the helicla flute 21 of steel matrix 1; Carbide bit 3 V-shaped structures, and be welded on the top of steel matrix 1.
The degree of depth of said helicla flute 21 is less than the radius of steel matrix 1.
The V-arrangement angle of said steel matrix 1 top v-shaped structure is the 90-150 degree.
Said steel matrix 1 crown center position has square groove 22, and its width is than the wide 0-1mm of the width of carbide bit 3.
The V-arrangement angle equal and opposite in direction of the V-arrangement angle of said hard alloy blocks and steel matrix 1 top v-shaped structure.
The outside dimension of said carbide bit 3 is greater than the external diameter of steel matrix 1, smaller or equal to the size sum of external diameter and 2 times of diamond abrasive grains 2 of steel matrix 1.
Compared with prior art, the beneficial effect of the utility model is:
(1) carbide bit of top V-arrangement is welded in the square groove at steel matrix top, helps drilling location, improves cutter speed down, and utilize that carbide alloy hardness is high, wear-resisting, a series of premium properties such as intensity and toughness are better, realize vertically quick drilling;
(2) matrix side helical groove structure design helps to reduce the frictional force between drilling, guarantees the smooth eliminating of drilling cuttings, smear metal;
(3) diamond brazing is on the helicla flute surface, and it is strong high that braze welding diamond abrasive grain has combination, strong to durability of diamond; Power consumption is little, and working (machining) efficiency is high, advantages such as long service life; Different diamond face has formed the distinct cutting angle, realizes the cross cutting in the drilling process.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment to the utility model further explain.
Shown in figure (1), a kind of drilling tool comprises steel matrix 1, diamond abrasive grain 2, carbide bit 3.
Wherein, steel matrix 1 surface distributed helicla flute 21, and its degree of depth is no more than the radius of steel matrix.In order to realize the helical feed chip removal effect of 21 pairs of drilling cuttings of helicla flute, smear metal, the rotation direction of helicla flute 21 is relevant with the work of the creeping into rotation direction of said drilling tool, and for clockwise, then helicla flute 21 is the dextrorotation rotation direction like the work of the creeping into rotation direction of drilling tool; The work of creeping into rotation direction like drilling tool is that then helicla flute 21 is left-handed rotation direction counterclockwise.The length that helicla flute 21 is distributed on steel matrix 1 surface is according to the degree of depth decision of processing, generally than the long 5-15mm of working depth.The top of steel matrix 1 is a v-shaped structure, and its V-arrangement angle is the 90-150 degree, and the crown center position of steel matrix 1 has square groove; Its width is than the wide 0-1mm of the width of carbide bit 3; Be used to weld carbide bit 3, make the bonding area of carbide bit 3 reach maximum, it is maximum that joint strength reaches; Stressed excessive when preventing work, fall cutter head.
Diamond abrasive grain 2 solderings are on the surface of the helicla flute 21 of steel matrix 1; Diamond abrasive grain 2 has the polyhedron characteristic of octahedron, granatohedron, cube, tetrahedron and hexakisooctahedron; Thereby can realize the distinct cutting angle, guarantee laterally cutting smoothly of the course of work.
After steel matrix 1 is ready to; Be connected on carbide bit 3 high frequency induction weldings in the square groove 22 at steel matrix 1 top; Then the surface of diamond abrasive grain 2 vacuum brazings at the helicla flute 21 of steel matrix 1; At last the side processing of putting the first edge on a knife or a pair of scissors is carried out in the V-shaped part of carbide bit 3, just obtained the drilling tool of the utility model.
