The specific embodiment
Fig. 1 to Fig. 5 shows the two-sided Indexable milling insert embodiment of one of the present utility model, this milling cutting insert comprises upper surface 1, lower surface 2, multiple sides 3 and multiple transition face 4, adjacent side 3 connects by transition face 4, side 3 by upper master after after knife face 8 and lower master knife face 9 form, transition face 4 is made up of upper minor flank 10 and lower minor flank 11, after upper master after knife face 8 and lower master the intersection of knife face 9 and upper minor flank 10 with the intersection of lower minor flank 11 in same plane, knife face 9 setting that is centrosymmetric after knife face 8 and lower master after upper master, the setting that is centrosymmetric of upper minor flank 10 and lower minor flank 11, lower surface 2 by upper surface 1 along after blade thickness median plane S symmetry again along the symmetrical gained of the axle C of blade center, structure and the shape of blade are simplified, difficulty of processing reduces greatly, formed precision improves greatly, the cutting ability of blade is obviously promoted.
Further, after main on blade, after knife face 8 and lower master, between knife face 9, form inside obtuse angle alpha, 170 ° of < α <180 °, between upper minor flank 10 and lower minor flank 11, form inside obtuse angles beta, 174 ° of < β <180 °, the preferred value of the present embodiment is, α=172 °, β=176 °, this makes milling cutting insert is to have positive relief angle, upper and lower rotational symmetric structure.Common double groove blade is negative relief angle blade, this kind of scheme will certainly reduce blade sharpness, increase the cutting load power of blade, and two-sided Indexable milling insert of the present utility model, adopt positive relief angle design, advantage is to guarantee, under the prerequisite of cutting edge high usage, not lose the cutting ability of blade, make blade still keep cutting edge, cut very brisk; And negative angle blade need to design the normal cutting of larger negative radial inclination angle and negative axial inclination guarantee blade conventionally on cutter, and two-sided Indexable milling insert self of the present utility model is just with positive relief angle, the very little angle that only need tilt slightly on cutter just can reach the cutting effect of negative angle blade under same condition, and cutting edge inclination while increasing blade cut, the chip space that increases cutter, makes chip discharge more smooth and easy.
Further, upper surface 1 and lower surface 2 are by locating surface 5, inclined plane 7 between rake face 6 and locating surface 5 and rake face 6 forms, rake face 6 is higher than locating surface 5, after upper master, knife face 8 is crossing with the rake face 6 of upper surface 1, after lower master, the rake face 6 of knife face 9 and lower surface 2 is crossing forms respectively a main cutting edge 12, upper minor flank 10 is crossing with the rake face 6 of upper surface 1, the rake face 6 of lower minor flank 11 and lower surface 2 is crossing forms respectively a lower front cutting edge 13, the protruding Circular Nose Cutting Edge that main cutting edge 12 is R1 by one section of radius and one section of tangent connecting to form of concave arc sword that radius is R2, front cutting edge 13 is the dome arcuation that radius is R3, each group main cutting edge 12 is connected to form corrugated cutting edge group with front cutting edge 13, the tangent line of main cutting edge 12 with respect to upper master after after knife face 8 and lower master the angle of the intersection of knife face 9 be γ, γ increases from 0 ° gradually along the protruding Circular Nose Cutting Edge of main cutting edge 12, intersection point place at protruding Circular Nose Cutting Edge and concave arc sword reaches maximum, reduce gradually along concave arc sword again, 0 °≤γ≤10 °, the tangent line of front cutting edge 13 is δ with respect to upper minor flank 10 with the angle of the intersection of lower minor flank 11, δ joins to holding to joining to holding with the protruding Circular Nose Cutting Edge of another main cutting edge 12 from front cutting edge 13 and the concave arc sword of main cutting edge 12 and reduces gradually, 0 °≤δ≤15 °.In the present embodiment, γ increases to 10 ° gradually from 0 °, then is reduced to 0 °, and δ is reduced to 0 ° gradually from 15 °.The cutting edge inclination that the design of this kind of tooth shape has guaranteed main cutting edge 12 always on the occasion of, while making blade cut, workpiece is to be in the state that is drawn rather than pressed, positive cutting edge inclination has increased the chip space of cutter, make chip discharge more smooth and easy, and the cutting edge inclination of regular variation makes blade present sharp state in the time of little cutting-in, blade cut is more brisk efficient, and blade is safe condition in the time of large cutting-in, blade strength increases, and blade cut is more reliable and more stable; The cutting edge inclination of having guaranteed front cutting edge 13 is always for just, and along with the increase of cutting feeding parameter, the cutting edge inclination that participates in the front cutting edge 13 cutting is increasing on the contrary, the bearing power that has guaranteed blade lathe in the time of high-speed cutting there will not be sharply increases phenomenon, thereby reduce the tipping probability of blade, and circular-arc front cutting edge 13 can reduce the surface roughness of workpiece to be machined, so that blade still can keep good suface processing quality in the time of high-speed cutting.
In the present embodiment, inclined plane 7 shape triangular in shape, inclined plane 7 reaches maximum with respect to the height of locating surface 5 in the junction of corresponding main cutting edge 12 and front cutting edge 13, and adjacent inclined plane 7 intersects at a point.Tooth shape design of the present utility model alters a great deal the curvature of the rake face 6 of blade, rake face 6 is directly connected with locating surface 5 and can causes the point of a knife intensity of blade too thin, by the mitigation transition on inclined plane 7, make blade still have very strong support in the weakest place of main cutting edge 12 and this blade of intersection point place of front cutting edge 13, guaranteed the security of cutter.
Two-sided Indexable milling insert of the present utility model, both can, for the general facing cut processing of 45 ° of tool cutting edge angles, can realize again 90 ° of facing cuts and square shoulder milling; Good suface processing quality when unique three-dimensional groove-shaped and corrugated tooth shape design not only can meet the roughing of high-speed cutting but also can guarantee semifinishing.
Although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model.Any those of ordinary skill in the art, in the situation that not departing from technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
