Abstract
The invention discloses an ultrahard knife tool which comprises a knife bar, wherein a taper hole is opened and installed in the knifepoint at the top end of a knife or in the basal body of the knife bar, simultaneously an ultrahard polycrystal blade is a cone with a same taper, the tapered ultrahard polycrystal blade is equipped in the taper hole which is opened and installed in the knifepoint at the top end of a knife or in the basal body of knife bar. Due to that an inserted tapered ultrahard polycrystal body is adapted in the invention to be made to a monolithic ultrahard polycrystal knife tool, the structure of the monolithic ultrahard knife tool is greatly simplified, and the intensity of the ultrahard knife tool is improved, thereby further decreasing the manufacturing cost of the knife tool.
Description
Technical field
The present invention relates to a kind of cutter, especially relate to a kind of superhard cutter.
Background technology
Diamond, cubic boron nitride are two kinds of the highest materials of hardness in the world, and wherein diamond hardness in all known substances is the highest, and cubic boron nitride hardness is only second to diamond, but its hear resistance and higher to the chemical stability of ferrous metal.Have good serviceability by superhard material powder and a small amount of bond through the superhard glomerocryst material that the HTHP sintering forms, be widely used in the machining tool field.But present superhard glomerocryst compound tool all adopts carbide alloy substrate and cutter hub welding method, and this method welding fastness is not enough, and ultra hard material layer is thin, can only be used for the fine finishining field.Though and monoblock type machine folder superhard cutter can be used for roughing and semifinishing, because the superhard material consumption is big, cost is higher, makes to use to be restricted.
Summary of the invention
Purpose of the present invention just is at superhard glomerocryst compound tool not prison welding, easily comes off, and the high problem of monoblock type machine folder superhard cutter production cost, thereby a kind of simple in structure, superhard cutter that intensity is higher is provided.
Purpose of the present invention can realize by following measure:
The present invention includes knife bar, offer taper hole on the point of a knife place on knife bar top or the knife bar matrix, simultaneously superhard glomerocryst blade also for have with the point of a knife on knife bar top or knife bar matrix on the corresponding cone of taper hole, the superhard glomerocryst blade of this taper is placed in the taper hole of offering on the point of a knife place on knife bar top or the knife bar matrix.
The cross sectional shape of the cone among the present invention is a polygon.Perhaps, the cross sectional shape of cone is circular or oval.Certainly, also can be other suitable shape.
The present invention has simplified the structure of monoblock type superhard cutter greatly owing to adopt the superhard polycrystal of plug-in type taper to make the superhard glomerocryst cutter of monoblock type, has improved the intensity of superhard cutter.The cutter production cost is further reduced.
Description of drawings
Accompanying drawing is a structural representation of the present invention;
The specific embodiment
The present invention does with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the present invention includes knife bar, offer taper hole on the point of a knife place on knife bar 1 top or the knife bar matrix, simultaneously superhard glomerocryst blade also for have with the point of a knife on knife bar top or knife bar matrix on the corresponding cone 2 of taper hole, this cone is identical with the taper hole tapering, and the superhard glomerocryst blade of this taper is placed on the point of a knife place on knife bar top or the knife bar matrix and offers in the taper hole.Its combination can be directly blade cone 2 to be inserted in the knife bar taper hole, also can combine by modes such as welding or sintering.
As shown in the figure, the present invention includes knife bar, offer taper hole on the point of a knife place on knife bar top or the knife bar matrix, simultaneously superhard glomerocryst blade is also for having the cone of identical tapering, and the superhard glomerocryst blade of this taper is placed in the taper hole of offering on the point of a knife place on knife bar top or the knife bar matrix.The cross sectional shape of cone is a polygon, as triangle, square, hexagon etc.
Embodiment 3
As shown in the figure, the present invention includes knife bar, offer taper hole on the point of a knife place on knife bar top or the knife bar matrix, simultaneously superhard glomerocryst blade is also for having the cone of identical tapering, and the superhard glomerocryst blade of this taper is placed in the taper hole of offering on the point of a knife place on knife bar top or the knife bar matrix.The cross sectional shape of cone is circular or oval.
Claims (3)
1. superhard cutter, it comprises knife bar (1), it is characterized in that: offer taper hole on the point of a knife place on described knife bar top or the knife bar matrix, simultaneously superhard glomerocryst blade also for have with the point of a knife on knife bar top or knife bar matrix on the corresponding cone (2) of taper hole, the superhard glomerocryst blade of this taper is arranged in the taper hole of offering on the point of a knife place on knife bar top or the knife bar matrix.
2. superhard cutter according to claim 1 is characterized in that: the cross sectional shape of described cone is a polygon.
3. superhard cutter according to claim 1 is characterized in that: the cross sectional shape of described cone is for circular or oval.
