Background technology
PCD milling cutter is a kind of diamond cutter, have that hardness is high, compression strength is high, thermal conductivity and the characteristic such as wearability is good, can obtain very high machining accuracy and working (machining) efficiency in high-speed cutting, due to this material characteristic, PCD milling cutter is widely used in cutting technology.
But PCD milling cutter of the prior art is in milling cylinder body process, easily at knife-edge part Integrated Chip, not only can cause wearing and tearing to processing work, affect its surface flatness, reduce working (machining) efficiency, consider dirt simultaneously to be worth doing and produce extrusion abrasion in the process of the edge of a knife and processing work break-in, the service life of PCD milling cutter is shortened greatly, increase processing cost.
Summary of the invention
The object of the invention is the defect for prior art, provide the novel PC D milling cutter that a kind of edge of a knife Integrated Chip is few, reduce the generation of edge of a knife Integrated Chip, effectively improve the service life of PCD milling cutter, the surface flatness of working (machining) efficiency and processing work, reduces costs.
The present invention is achieved by the following technical solutions:
The novel PC D milling cutter that a kind of edge of a knife Integrated Chip is few, comprise handle of a knife and four leaf cutter heads, wherein, described handle of a knife tail end is provided with mounting groove to handle of a knife internal direction, described mounting groove is by axle head link slot, seal groove and locking positioning groove composition, described seal groove two ends are connected with locking positioning groove with axle head link slot respectively, described locking positioning slot is in handle of a knife tail end, pivot pin is provided with in described axle head link slot, described pivot pin surface is provided with some projections, described some projections are arranged around pivot pin for one week, described seal groove inwall is provided with some sealing rings, described some sealing ring parallel interval are arranged, described locking positioning groove is provided with locating hole, described locating hole two ends cause in handle of a knife surface, described handle of a knife both sides are respectively equipped with the first connecting hole and the second connecting hole, described first connecting hole and the second connecting hole position correspondence are arranged, described four leaf cutter heads comprise the first blade, second blade, 3rd blade and the 4th blade, described first blade, second blade, 3rd blade and the 4th blade in order tail end are vertically connected, and all there is PCD blade, described PCD blade top is provided with axial positive rake angle, the number of degrees θ of described axial positive rake angle is 15 °.
The novel PC D milling cutter that above-mentioned a kind of edge of a knife Integrated Chip is few, wherein, described handle of a knife surface is provided with recessed groove.
Beneficial effect of the present invention is:
The mounting groove structure of handle of a knife of the present invention, ensure that PCD milling cutter installation reliability, under high pressure is stressed, not easily loosens; The present invention is provided with the axial positive rake angle of 15 ° on the PCD blade of four leaf cutter heads, compare conventional P CD milling cutter, this angle has done suitable increase, while guarantee cutting dynamics, be conducive to formation and the eliminating of cutting, thus reduce the generation of edge of a knife Integrated Chip, effectively improve the service life of PCD milling cutter, the surface flatness of working (machining) efficiency and processing work, reduces costs.
