The specific embodiment
Explain the preferred embodiment of the centering helical tooth blade of compound location of the present invention combined cut below in conjunction with accompanying drawing, mainly describe as an example of cutter with two spiral bar example in embodiment 1-4.
Embodiment 1
as shown in Figure 1, the centering helical tooth blade of the compound location combined cut of the 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 rear cutting face 20, the outermost surface of spiral bar is helical stand 16, side edge 10 with the top, be formed with screw pair sword 12 between helical stand 16 and cutting face 19, spiral positioning platform 11, the second secondary sword 13, divide tangent plane 22, helical stand 16 and the crossing side edge 10 that is formed with in rear cutting face 20, spiral cutting face 19 and the crossing cutting edge 8 that is formed with in rear cutting face 20, rear cutting face 20 and the crossing minute cutting blade 9 that is formed with of minute tangent plane 22, intersect with compound positioning table 11 and be formed with the second side edge 17, on rear cutting face 20, fluted 21 intersect with cutting face 19 and are formed with recess sword 14, 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 arrange certain anxious bevel 23, both sides top or chisel edge 1 respectively have a centering to cut sword 2, the outside of centering minute cutting blade 2 is location minute cutting blade 3, positioning table 24 and little side edge 4 and positioning cutting sword 5 and locating pair cutting edge 6, the compound locating pair cutting edge 7 of the anterior projection of apex point, front cutting edge 8.
according to said structure, due to the center of cutterhead 18 top bump be provided with an apex point therefore this cutter have good stability, again owing to being provided with the cutting hardness that has reduced cutterhead 18 when the recess sword makes this cutter at the cutting sheet metal on cutting edge, form along front cutting edge 12 platform 11 that also dispels the heat, and be formed with the 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 again second a new front cutting edge 13, 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 simultaneously the area of dissipation of cutterhead, reduce the cutterhead temperature, extended cutter life, and keep high strength in process always.
As shown in Figure 2, the centering helical tooth blade of the compound location combined cut of the second embodiment of the present invention changes to the cutting edge 8 in the outside on the basis of embodiment one with screw pair cutting edge 12 angles greater than cutting edge 15 and a minute cutting blade 9 of 90
By cutterhead being made the 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 positioning cutting sword 5 of both sides and centering minute cutting blade 2 form with chisel edge the stressed service life that reduces to extend cutterhead that the S sword has extended each cutting edge sum and made centering minute cutting blade 2 location minute cutting blades 3.
By so consisting of, on the basis of the technique effect of embodiment 1-2, due to the centre of location that has formed a compound location combined cut on common cutter head in the past, can better locate, further improve machining accuracy in process, and prevent from because locating shakiness, problem that workpiece is taken up occuring when the thinner workpiece of drilling, can effectively prevent the generation of burr simultaneously when the workpiece of the easy grain raising of drilling.
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 arranges the spiral heat dissipation platform 11 in inboard compound setting screw platform 24 and the outside thereby improved cutterhead on the helical stand on apex point and the outside stock-removing efficiency has extended cutterhead at described cutting edge 8.
By so consisting of, on the basis of the technique effect of embodiment 1, owing to therefore having processed the garden platform at described cutting edge on workpiece for sword always and can having raised the efficiency greatly and extend service life of cutterhead.
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 front cutting edge 8, making apex point both sides is triangle
By so consisting of, on the basis of the technique effect of embodiment 1-4, what stay is the location that a conical surface is conducive to depth drill after boring on workpiece so because apex point forms triangle, this cutterhead is owing to being formed with the spiral heat dissipation platform in the outside, resistance when being formed with minute cutting blade on cutting edge and having decomposed cutterhead in cutting has kept the stock-removing efficiency of cutterhead, has extended the service life of cutterhead, and keep high strength in drilling processing always, increase work efficiency.
The shank of tool of present embodiment can adopt the structure identical with embodiment 1, and therefore the description thereof will be omitted at this.
Although abovely be illustrated as an example of cutter with two spiral bar example, 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 the compound location combined cut with triangle apex point as Fig. 5, the spiral heat dissipation platform of every, centering minute cutting blade structure is all identical with embodiment 1-4.
Above-described preferred embodiment is illustrative and not restrictive, in the situation that do 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.
