Abstract
The utility model discloses a polycrystalline cubic boron nitride (PCBN) located mode round cutter blade which comprises a cutter body, wherein the cutter body is in a cone-frustum shape. A PCBN cutting portion is arranged on one edge of the end face of the front side of the cutter body. An included angle between a conical surface of the side face of the cutter body and a center shaft of the cutter body is 7 degrees. At least two tapered planes are arranged on one circle outer edge of the end face of the rear side of the cutter body, wherein the tapered planes are used for clamping and locating. An included angle between each tapered plane and a center shaft of the cutter blade is 14 degrees. Eight tapered planes are uniformly arranged on one circle outer edge of the end face of the rear side of the cutter body, wherein the tapered planes are used for clamping and locating. The thickness of the cutter body is 6.35 mm. The PCBN located mode round cutter blade is simple in structure and practical in function. The tapered planes are additionally arranegd on the cutter body as locating planes so that clamping can be precisely conducted in one time. Meanwhile, when the cutter blade is polished and blade-replaced in many times, production time is reduced and the production benefits are enhanced.
Description
Technical field
The utility model relates to a kind of PCBN locate mode circular shear blade.
Background technology
As shown in Figure 1, 2, present blade is truncated cone, comprise cutter hub 1 and cutting tip 2, the angle α of the conical surface of cutter hub side and cutter hub axis is 7 °, clamping gets up all inconvenient, wastes time and energy, and can not accurately locate when clamping, production efficiency is low in actual production is used, and affects product quality.
The utility model content
The utility model provides a kind of PCBN locate mode circular shear blade, convenient mounting and clamping.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of PCBN locate mode circular shear blade, the cutter hub that comprises truncated cone, one edge of cutter hub anterior end surface is provided with the PCBN cutting tip, the angle of the conical surface of cutter hub side and cutter hub axis is 7 °, is provided with at least two tapered planes that are used for the clamping location on all outers of cutter hub rear side end face.
The angle of tapered plane and blade axis is 14 °.
Evenly be provided with eight tapered planes that are used for the clamping location on one all outers of cutter hub rear side end face.
