Abstract
The utility model belongs to the field of cutters, and particularly relates to a high-strength high temperature-resistant coated twist drill. A coated sold carbide ball cutter comprises a connected cutter bar, and is characterized in that the front end of the cutter bar is integrally provided with a bulb cutting part; the bulb cutting part is provided with a chip groove extending onto the cutter bar; the spherical surface of the bulb cutting part is a reducing spherical surface, and the diameter is gradually reduced from a cutting edge to the chip groove; the surface of the bulb cutting part is provided with a carbon nitride coating. The bulb cutting part and the cutter bar are integrated, so that the rigidity of the whole cutter is improved, and the cutter can bear larger torque in the cutting process; meanwhile, the bulb cutting part is reducing, and the friction between the cutting edge and the surface of a workpiece is reduced and the cutting resistance is reduced under the condition of ensuring the strength of the cutting edge; in addition, by the carbon nitride coating arranged on the surface, the strength of the cutter is improved and a new requirement of a new material on the cutter is met.
Description
Technical field
The utility model belongs to cutting tool field, particularly a kind of coating Integral alloy ball cutter.
Background technology
At present, the mode that existing ball cutter generally adopts bulb and knife bar parts processing to be then welded and fixed, because the cutting output of ball cutter is larger, the intensity of the ball cutter that processing mode processes like this cannot meet the requirement of cutting, usually there is the phenomenon of breaking, have a strong impact on normally carrying out of producing, while is along with the development of economic society, the exploitation of various new materials, the ball cutter of traditional carbide alloy can not adaptation material development, in addition, the bulb diameter of existing ball cutter is identical, after cutting, the friction of cutter and workpiece is larger, increase cutting resistance, on there is impact the service life of cutter.
Utility model content
The utility model is for the deficiencies in the prior art, and the utility model has designed a kind of integrated machine-shaping, and the diameter of bulb is that reducing and surface are provided with the coating whole hard alloy cutter that strengthens coating.
The utility model is achieved through the following technical solutions:
Coating Integral alloy ball cutter, it comprises the knife bar of connection, it is characterized in that: the front end of described knife bar has been wholely set bulb cutting portion, on bulb cutting portion, be provided with the chip area extending on knife bar, the sphere of described bulb cutting portion is the sphere of a reducing, diameter from cutting edge to chip area is descending, and the surface of described ball cutter cutting portion is provided with carbon nitride coatings.
The diameter of described bulb cutting portion is 4.0～4.5mm.
The edge of described chip area is provided with limit cutting edge.
In sum, the utlity model has beneficial effect:
Bulb cutting portion of the present utility model and the integrated setting of knife bar, increase the rigidity of whole cutter, can in working angles, bear larger moment of torsion, bulb cutting portion adopts the design of reducing simultaneously, in the situation that ensureing edge strength, reduce the friction of blade and surface of the work, reduce cutting resistance, the carbon nitride coatings that surface arranges has in addition increased the intensity of cutter, meets the new requirement that new material proposes cutter.
Brief description of the drawings
By the detailed description below in conjunction with accompanying drawing, the utility model is aforesaid will be become apparent with other object, feature and advantage.Wherein:
Figure 1 shows that structural representation of the present utility model;
In figure, 1 is bulb cutting portion, and 2 is chip area, and 3 is limit cutting edge, and 4 is knife bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Coating Integral alloy ball cutter as shown in Figure 1, it comprises the knife bar 4 of connection, it is characterized in that: the front end of described knife bar 4 has been wholely set bulb cutting portion 1, on bulb cutting portion 1, be provided with the chip area 2 extending on knife bar, the sphere of described bulb cutting portion 1 is the sphere of a reducing, diameter from cutting edge to chip area is descending, and the surface of described ball cutter cutting portion 1 is provided with carbon nitride coatings.
The diameter of further, described bulb cutting portion 1 is 4.0～4.5mm.
The edge of further, described chip area 2 is provided with limit cutting edge 3.
In sum, the utlity model has beneficial effect:
Bulb cutting portion of the present utility model and the integrated setting of knife bar, increase the rigidity of whole cutter, can in working angles, bear larger moment of torsion, bulb cutting portion adopts the design of reducing simultaneously, in the situation that ensureing edge strength, reduce the friction of blade and surface of the work, reduce cutting resistance, the carbon nitride coatings that surface arranges has in addition increased the intensity of cutter, meets the new requirement that new material proposes cutter.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
