Abstract
The utility model belongs to superhard cutter technical field, particularly relate to the two-sided compound PCBN blade of a kind of band relief angle, described two-sided compound PCBN blade is integral type structure, blade is divided into cutting tip and lower cutting tip, upper cutting tip and lower cutting tip are all with relief angle, there is rotation angle α in upper cutting tip and lower cutting tip, α is 2 ° ~ 20 °.Relative to prior art, the utility model blade is adding man-hour, be processed with relief angle, like this with the use of knife bar processing relief angle, only need two the corresponding cutting edges up and down making Whole PC BN blade to stagger just, decrease the increase of blade cut angle of cutting edge, decrease the drag of workpiece to blade simultaneously, decrease the wearing and tearing of workpiece to blade, extend blade service life.
Description
Technical field
The utility model belongs to superhard cutter technical field, particularly relates to the two-sided compound PCBN blade of a kind of band relief angle.
Background technology
At present, in order to make full use of each cutting edge of PCBN blade, Whole PC BN blade is when producing, do not process relief angle, but in use, need to coordinate to the knife bar or cutterhead that are processed with corresponding relief angle, cause the anterior angle of cutting edge to increase like this, workpiece increases the drag of blade, accelerates the wearing and tearing of blade.
Utility model content
The technical problems to be solved in the utility model is that Whole PC BN blade needs to coordinate with the knife bar or cutterhead that are processed with relief angle in use, the anterior angle of blade cut sword is caused to increase, accelerating the wearing and tearing of blade, for solving the problem, providing a kind of band relief angle Whole PC BN blade.
The purpose of this utility model realizes in the following manner:
The two-sided compound PCBN blade of a kind of band relief angle, described two-sided compound PCBN blade is integral type structure, and blade is divided into cutting tip and lower cutting tip, and upper cutting tip and lower cutting tip are all with relief angle, there is rotation angle α in upper cutting tip and lower cutting tip, α is 2 ° ~ 20 °.
Described relief angles is 3 °, 5 °, 7 °, 11 °, 15 °, 20 °, 25 ° or 30 °.
Described two-sided compound PCBN blade cross section shape is regular polygon, triangle or rhombus.
Relative to prior art, the utility model blade is adding man-hour, be processed with relief angle, like this with the use of knife bar processing relief angle, only need two the corresponding cutting edges up and down making Whole PC BN blade to stagger just, decrease the increase of blade cut angle of cutting edge, decrease the drag of workpiece to blade simultaneously, decrease the wearing and tearing of workpiece to blade, extend blade service life.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is Fig. 1 stereogram.
Wherein, 1 is upper cutting tip; 2 is lower cutting tips.
Detailed description of the invention
