The technical scheme that patent of the present invention adopts is: a kind of superhard cutting blade with anti-rake wear chip-breaking, comprise the matrix that square carbide alloy is made, the cutting edge that one deck first polycrystalline cubic boron nitride layer is formed is had in the bight of matrix, the negative chamfer structure at cutting edge edge, it is characterized in that: the chip-breaking being also welded with boss shape on described blade cut sword, described chip-breaking is the structure of moving back platform shape on the cutting edge, described chip-breaking is the high-termal conductivity second polycrystalline cubic boron nitride layer of high cBN content, chip-breaking is embedded on point of a knife rake face by Vacuum Soldering Technology.
Say further, described cutting edge is low cBN content PCBN.
Say further, described chip-breaking is welded on above point of a knife by vacuum brazing method, and brazing solder composition is Ag, Cu or Ti.
Say further, described chip-breaking is inverted trapezoidal, and inverted trapezoidal angle [alpha] is 20 °-60 °, and inverted trapezoidal height b is 0.2-1mm, is 0.1-1mm with negative chamfered edge distance c bottom chip-breaking.
Say further, described blade cut cutlery has negative chamfer structure, and negative chamfered edge width a is 0.05-0.5mm, and negative chamfered edge angle beta is 15 °-45 °.
Say further, the convex type chip-breaking that described blade circular arc point of a knife place is corresponding is arc structure, and arc radius R is 0.1-1.2mm.
Say further, the position that described matrix installs cutting edge subtracts material structure.
The beneficial effect of patent of the present invention is: such superhard cutting blade has the effect of chip breaking, heat radiation due to chip-breaking, while cutter being had do not damage cutting edge, improves the advantage of chip-breaking suface processing quality; Described cutting edge is low cBN content PCBN, also has the advantage that cutter is sharper; Described chip-breaking is embedded on point of a knife rake face by Vacuum Soldering Technology, and brazing solder composition is Ag, Cu or Ti, also has chip-breaking and cutter head and combine advantage that is better, heat extraction better effects if;
Described chip-breaking is inverted trapezoidal, inverted trapezoidal angle [alpha] is 20 °-60 °, inverted trapezoidal height b is 0.2-1mm, be 0.1-1mm with negative chamfered edge distance c bottom chip-breaking, described blade cut cutlery has negative chamfer structure, negative chamfered edge width a is 0.05-0.5mm, and negative chamfered edge angle beta is 15 °-45 °, has and designs more reasonably advantage;
The position that described matrix installs cutting edge subtracts material structure, has cutter head more firmly advantage on matrix.

Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As Fig. 1, 2, shown in 3, a kind of superhard cutting blade with anti-rake wear chip-breaking, comprise the matrix 1 that square carbide alloy is made, the cutting edge 2 that one deck first polycrystalline cubic boron nitride layer is formed is had in the bight of matrix, the negative chamfer structure at cutting edge edge, it is characterized in that: the chip-breaking 3 being also welded with boss shape on described blade cut sword, described chip-breaking is the structure of moving back platform shape on the cutting edge, described chip-breaking is the high-termal conductivity second polycrystalline cubic boron nitride layer of high cBN content, chip-breaking is embedded on point of a knife rake face by Vacuum Soldering Technology.
Polycrystalline cubic boron nitride is divided into two classes substantially: a class is high cBN content PCBN, and internal structure is the high density cBN bond that a small amount of binding agent is assisted, and performance shows as high thermal conductivity; Another kind of is low cBN content PCBN; internal structure is that the coated cBN particle sintering of vitrified bonding forms; performance shows as high red hardness; there is floor height cBN content boron nitride glomerocryst layer a---chip-breaking in face on the cutting edge; the heat that the first polycrystalline cubic boron nitride layer can be made to produce is discharged in time; be conducive to protecting cutting edge, have this advantage of the present utility model, chip-breaking uses low cBN content PCBN also to have the effect of chip breaking.Message itself is had chip-breaking material to be chosen as high heat-conducting type PCBN glomerocryst dexterously, not only chip breaking is respond well, and there is high rigidity, it covers the significant heat-sinking capability improving rake face on rake face, therefore the generation of rake wear can effectively be suppressed, thus realize the double action of anti-rake wear and chip breaking simultaneously, processing high-hardness steel workpiece surface quality and cutter life are significantly improved.
Described move back the part edge that platform shape structure refers to above part edge is inner below, namely upper part has the structure of drawing back.
Say further, described cutting edge is low cBN content PCBN.Be exactly utilize low cBN content PCBN to have the effect of good hardness like this.
Say further, described chip-breaking is welded on above point of a knife by vacuum brazing method, and brazing solder composition is Ag, Cu or Ti.
Say further, described chip-breaking is inverted trapezoidal, and inverted trapezoidal angle [alpha] is 20 °-60 °, and inverted trapezoidal height b is 0.2-1mm, is 0.1-1mm with negative chamfered edge distance c bottom chip-breaking.
Say further, described blade cut cutlery has negative chamfer structure, and negative chamfered edge width a is 0.05-0.5mm, and negative chamfered edge angle beta is 15 °-45 °.
Say further, the convex type chip-breaking that described blade circular arc point of a knife place is corresponding is arc structure, and arc radius R is 0.1-1.2mm.
Say further, the position that described matrix installs cutting edge subtracts material structure.
