Detailed description of the invention
An embodiment of a kind of slotting cutter of the utility model is as shown in Fig. 1 ~ Fig. 4, comprise handle of a knife 1 and cutting head 2, described cutting head 2 comprises three cutting edges, be respectively the triangular cutting edge 4, scalloped cutting edge 5 and the circular blade 6 that are uniformly distributed along the circumference and be arranged in order along the direction of rotation of slotting cutter, each cutting edge all stretches out handle of a knife 1 vertically, has towards the medial surface at slotting cutter center with towards the lateral surface of slotting cutter outside.Each cutting edge comprises the connecting portion 32 between handle of a knife 1 and the cutting edge portion 31 that is arranged on the cutting edge portion 31 for cutting workpiece at top and is connected to slotting cutter, as shown in Figure 2, the part that the lateral surface of each cutting edge is corresponding with connecting portion is on the same circumference of the dead in line of axis of rotation and slotting cutter.
The medial surface of triangular cutting edge 4, scalloped cutting edge 5 and circular blade 6 corresponding to the part of cutting edge portion 31 be separately respectively plane, towards the arcwall face 51 of slotting cutter radially outer depression with towards the arc surface 61 of slotting cutter radial center projection, wherein the plane on triangular cutting edge 4 is the clinoplain 41 radially being tilted laterally to cutting edge portion by the root of cutting edge, and the axis of rotation of arcwall face 51 and arc surface 61 is all perpendicular to the axis of slotting cutter; The lateral surface of triangular cutting edge 4, scalloped cutting edge 5 and circular blade 6 corresponding to the part of cutting edge portion 31 be separately respectively the sphere 42 outstanding towards slotting cutter radially outer, towards the axially consistent face of cylinder 62 of the bearing of trend of the outstanding cambered surface 52 of slotting cutter radially outer and bus and slotting cutter, the top of scalloped cutting edge 5 have between cambered surface of being connected to 52 and arcwall face 51 and with axially vertical joint face of slotting cutter, the top of circular blade 6 have be connected between its face of cylinder 62 and arc surface 61 and with axially vertical top planes 63 of slotting cutter.The cutting edge portion of triangular cutting edge 4 is intersected and is formed by sphere 42 and clinoplain 41, and the cutting edge portion of scalloped cutting edge 5 is formed by cambered surface 52, arcwall face 51 and above-mentioned joint face, and the cutting edge portion of circular blade 6 is formed by the face of cylinder 62, arc surface 61 and above-mentioned top planes 63; The radial dimension of joint face is less than the radial dimension of top planes 63.
Adopt said structure, due to triangular cutting edge 4, radial dimension between scalloped cutting edge 5 and circular blade 6 medial surface and the lateral surface corresponding with cutting edge portion is all not identical, the above-mentioned radial dimension of adjacent two cutting edges increases successively along the direction of rotation of slotting cutter, therefore triangular cutting edge 4, the intensity of scalloped cutting edge 5 and circular blade 6 increases successively, although sharpness reduces successively, but the cutting edge that the cutting edge that radial dimension is less and radial dimension are larger is mutually collaborative, in working angles, each cutting edge intermittently contacts with workpiece, thereby can avoid cutting edge portion 31 overheated, and can improve stock-removing efficiency, reduce the wearing and tearing of cutting edge, be conducive to extend cutter life.For reaching the better anti-object of crossing thermal effect and extending cutter life, the height of triangular cutting edge 4 is less than the height of scalloped cutting edge 5 and circular blade 6.
Tangential direction along corresponding cutting edge lateral surface is observed, each cutting edge all has the inclined plane being connected between handle of a knife 1 and cutting edge portion 31 separately, and, along the end on observation of slotting cutter, the intersection 7 of the root of each cutting edge and handle of a knife 1 connecting place is camber line, so just increase the joint face area of each cutting edge and handle of a knife 1, thereby contributed to promote the bonding strength of each cutting edge and handle of a knife 1, avoided cutting edge portion 31 to occur the situation of distortion, tipping, fracture.
In the above-described embodiments, cutting edge is provided with three, and the cutting edge portion of each cutting edge is respectively triangle, fan-shaped and circular, in other embodiment of the present utility model, more than the quantity of cutting edge also can be arranged to two or four, it is attainable that this is that those skilled in the art do not need to pay creative work, and the shape of each cutting edge cutting edge portion is also not limited to above-mentioned three kinds of shapes, for example above-described embodiment intermediate cam shape sword 4 can be arranged to the face of cylinder corresponding to the lateral surface of cutting edge portion, as long as be provided with the cutting edge different from its radial dimension, can play equally and improve collaborative effect mutually.In addition, the material that is difficult to cutting at processing plain cutter, during such as the larger material of hardness, the ultra hard material layer that also can be formed by superhard material monocrystalline or ultra-hard material poly-crystal in the outer surface setting of each cutting edge cutting edge portion, this ultra hard material layer does not affect the cutting edge portion shape of each cutting edge, and can make process more smooth, improve working (machining) efficiency.
