The specific embodiment
Explain the preferred implementation of the centering helical tooth blade of compound location of the present invention combined cut below in conjunction with accompanying drawing, main in embodiment 1-4 is that example describes with the cutter with two spiral bar.
Embodiment 1
As shown in Figure 1, the centering helical tooth blade of the compound location combined cut of first embodiment of the present invention, comprise cutterhead 18, cutterhead 18 is provided with two spiral bar integratedly, the face towards cutting direction of spiral bar is cutting face 19, the top rear side in cutting face 19 is cutting face 20, back, the outermost surface of spiral bar is a helical stand 16, side edge 10 with the top, be formed with screw pair sword 12 between helical stand 16 and the cutting face 19, spiral positioning platform 11, the second secondary sword 13, divide tangent plane 22, helical stand 16 and cutting face, the back 20 crossing side edges 10 that are formed with, spiral cutting face 19 and cutting face, the back 20 crossing cutting edges 8 that are formed with, back cutting face 20 and the branch tangent plane 22 crossing branch cutting blades 9 that are formed with, with compound positioning table 11 crossing second side edges 17 that are formed with, fluted 21 intersect with cutting face 19 and to be formed with recess swords 14 on the back cutting face 20, the bottom of this recess sword 14 can be trapezoidal, arc, triangle, square and arbitrary shape, the top central protuberance of the centering helical tooth blade of compound location combined cut be provided with an apex point, the tip of apex point is top or chisel edge 1, its both sides respectively are provided with certain anxious bevel 23, both sides top or chisel edge 1 respectively have a centering to cut sword 2, and centering divides the outside of cutting blade 2 to divide cutting blade 3 for the location, positioning table 24 and little side edge 4 and location cutting edge 5 and locating pair cutting edge 6, the compound locating pair cutting edge 7 of the anterior projection of apex point, preceding cutting edge 8.
According to said structure, since the center of cutterhead 18 top bump be provided with an apex point therefore this cutter have good stability, because being provided with the recess sword, cutting edge make this cutter when the cutting sheet metal, reduce the cutting hardness of cutterhead 18 again, form the platform 11 that also dispels the heat along front cutting edge 12, and be formed with second front cutting edge 13 in the front portion towards cutting direction of this heat radiation platform 11, so compare with cutter head in the past, increased by second a new front cutting edge 13 again, can carry out work with two front cutting edges thus, thereby the cutting force that can decompose front cutting edge, reduce the frictional strength of front cutting edge, the frictional heat generation is reduced, can also increase the area of dissipation of cutterhead simultaneously, reduce the cutterhead temperature, prolonged cutter life, and in process, keep high strength always.
As shown in Figure 2, the centering helical tooth blade of the compound location combined cut of second embodiment of the present invention, on the basis of embodiment one, the cutting edge 8 in the outside changed to screw pair cutting edge 12 angles greater than 90 cutting edge 15 with divide cutting blade 9
By cutterhead being made structure as being, can enlarge the scope of application of cutter of the present invention, can be applied to can prevent effectively that cutterhead from collapsing tooth in the processing of multiple uneven workpiece.
Embodiment 3
As shown in Figure 3, the centering helical tooth blade of the compound location combined cut of the 3rd embodiment of the present invention, first, in the structure of two embodiments, cutting edge 8 in each spiral bar, 9 cancellations are processed into and groove 21, the recess sword 14 of recess sword 14 rounding ofves and groove 21, the center of apex point are arranged to parallel with two outer edge or are had the chisel edge 1 of minimum angle to make the location cutting edge 5 of both sides and centering divide cutting blade 2 and chisel edge formation S sword to prolong each cutting edge sum and made centering divide the stressed service life that reduces to prolong cutterhead of cutting blade 2 location branch cutting blades 3.
By so constituting, on the basis of the technique effect of embodiment 1-2, owing on common cutter head in the past, formed the centre of location of a compound location combined cut, in process, can better locate, further improve machining accuracy, and prevent from because of locating shakiness problem that workpiece is taken up to take place when the thin workpiece of drilling, when the workpiece of the easy grain raising of drilling, can prevent the generation of burr simultaneously effectively.
Embodiment 4
As shown in Figure 4, the centering helical tooth blade of the compound location combined cut of the 4th embodiment of the present invention, in the structure of the one two three embodiment, it is the service life that a straight straight sword 8 is provided with the spiral heat dissipation platform 11 in the inboard compound setting screw platform 24 and the outside thereby has improved cutterhead on the helical stand on the apex point and the outside stock-removing efficiency has prolonged cutterhead at described cutting edge 8.
By so constituting, on the basis of the technique effect of embodiment 1, owing to therefore on workpiece, processed the garden platform for sword always and can raise the efficiency and prolong service life of cutterhead greatly at described cutting edge.
Embodiment 5
As shown in Figure 5, the centering helical tooth blade of the compound location combined cut of the 5th embodiment of the present invention in the structure of the first-four embodiment, is being removed locating pair cutting edge 6 from apex point, compound locating pair cutting edge 7 and preceding cutting edge 8, making the apex point both sides is triangle
By so constituting, on the basis of the technique effect of embodiment 1-4, what stay is the location that a conical surface helps depth drill after boring on the workpiece so because apex point forms triangle, this cutterhead is owing to be formed with the spiral heat dissipation platform in the outside, resistance when being formed with the branch cutting blade on the cutting edge and having decomposed cutterhead in cutting has kept the stock-removing efficiency of cutterhead, has prolonged the service life of cutterhead, and in drilling processing, keep high strength always, increase work efficiency.
The shank of tool of present embodiment can adopt the structure identical with embodiment 1, therefore omits its explanation at this.
Though more than be that example is illustrated with cutter with two spiral bar, cutter of the present invention also can have a plurality of spiral bar, can adopt as described the structure of embodiment and the combination of other arbitrary form thereof on each spiral bar.Show the centering helical tooth blade of compound location combined cut as Fig. 5 with triangle apex point, every spiral heat dissipation platform, centering divides the cutting blade structure all identical with embodiment 1-4.
Above-described preferred implementation is illustrative and not restrictive, and under the situation that does not break away from purport of the present invention and essential characteristic, the present invention can also otherwise implement and specialize.Scope of the present invention is limited by claim, and all distortion in the claim limited range all fall within the scope of the present invention.
