Abstract
The utility model relates to a superhard cutter technical field specifically is an overall sintering triangle -shaped PCBN blade, including the overall sintering blade, be provided with the fixed slot on the blade, the cross section of fixed slot is triangle -shaped. Compared with the prior art, the utility model discloses be provided with the cross section for triangle -shaped's fixed slot on the stationary plane of blade body, the fixed slot prevents that the blade from at the effect of vibration departure from the cutter arbor down, having improved the security of working. And set up the fixed slot that the cross section is triangle -shaped on the stationary plane of blade, and prevent that the blade from under the effect of atress and vibration, taking place to deflect, improve workpiece surface's machining precision.
Description
Technical field
The utility model relates to superhard cutter technical field, is specially a kind of integral sintered trilateral PCBN blade.
Background technology
Owing to the material of T-shaped PCBN is harder, when blade is arranged on knife bar, what generally adopt is that upper pressure type compresses, but there is certain deviation in the quality of fit between blade and knife bar, cutter is adding man-hour, and blade has certain displacement relative to knife bar, thus causes the sideslip of point of penetration, cause the workpiece of processing defective, and when tool sharpening, vibrate bigger, there will be the phenomenon that blade flies from knife bar, danger is higher, also affects the processing quality of blade face. In the prior art, the generation for preventing above phenomenon having, blade face is provided with frustum type groove, which prevent the phenomenon generation that blade flies from knife bar, but, due to the frustum type groove adopted, blade is when by power and vibration, there will be the phenomenon of blade deflection, cause the workpiece accuracy of processing not up to standard.
Practical novel content
The technical problems to be solved in the utility model is: blade when by power and vibration, there will be the phenomenon of blade deflection at blade, causes the workpiece accuracy of processing not up to standard, for solving the problem, it is provided that a kind of integral sintered trilateral PCBN blade.
The purpose of this utility model realizes in the following manner:
A kind of integral sintered trilateral PCBN blade, comprises integral sintered blade, is provided with pickup groove on blade, and the cross section of pickup groove is trilateral.
Pickup groove is arranged on the both sides of blade.
The drift angle place of pickup groove is circular arc.
The drift angle of pickup groove is positioned on the center line of blade body.
The degree of depth of pickup groove is 0.5-3mm.
Relative to prior art, the utility model is provided with the pickup groove that cross section is trilateral on the fixed face of blade body, and pickup groove prevents blade from flying under the effect of vibration from knife bar, it is to increase the security of work. And the pickup groove that cross section is trilateral is set on the fixed face of blade, it is prevent blade under the effect by power and vibration, deflects, it is to increase the working accuracy of workpiece surface.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 is blade;2 is pickup groove.
Embodiment
As shown in Figure 1, a kind of integral sintered trilateral PCBN blade, comprises integral sintered blade 1, is provided with pickup groove 2 on blade 1, and the cross section of pickup groove 2 is trilateral. Pickup groove 2 is arranged on the both sides of blade. The drift angle place of pickup groove 2 is circular arc. The drift angle of pickup groove 2 is positioned on the center line of blade body. The degree of depth of pickup groove 2 is 0.5-3mm, such as 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, it may also be useful to time, on blade 1, the degree of depth of pickup groove 2 is relevant with the thickness of blade.
