Abstract
The invention discloses a kind of cutting tip, comprise the blade body in polygon tabular, described blade body is surrounded by multiple sides of upper surface, lower surface and connection upper and lower surface, described upper surface and side one_to_one corresponding, between described side and upper surface, angle is acute angle, and at least one side and upper surface intersect formation continuous cutting sword, on upper surface direction, described continuous cutting sword is linearly, in the lateral direction, and described continuous cutting sword concave-convex surface.This cutting tip has the making being convenient to mould, compressing convenience, advantage that cutting ability is stable.
Description
Technical field
The present invention relates to the cutting tip with continuous cutting blade, particularly relate to the cutting tip with concavo-convex cutting edge.
Background technology
It has been found that, in machining, concavo-convex cutting edge is when cutting workpiece, and its concavo-convex cutting edge is not cut simultaneously, and concavo-convex cutting edge gradually and absorption surface, impact can be relaxed fully, reduce cutting force, meanwhile, the chip that the blade incision workpiece with concavo-convex cutting blade structure produces is more broken, in working angles, less chip can discharge fast, easily, effectively avoids chip scratch finished surface.Because the blade with concaveconvex structure cutting edge has the above feature, so this type of blade is widely used in intermetallic composite coating.This type of cutting tip generally adopts structure as shown in Figure 1 to Figure 3, blade body 1 is surrounded by multiple sides 4 of upper surface 2, lower surface 3 and connection upper and lower surface, upper surface 2 and side 4 one_to_one corresponding, there are one or more side 4 and upper surface 2 to intersect and form continuous cutting sword 6, on upper surface 2 and direction, side 4, continuous cutting sword 6 all has concavo-convex cutting blade structure.
Although this structure cutting tip has advantage described above, but upper surface and side surface direction all have the cutting tip of concavo-convex cutting edge, its cutting edge portion is comparatively complicated, the mould and die accuracy of blade is difficult to ensure, compressing difficulty, and the product suppressed easily occurs crackle, qualification rate is low; In addition, due to the shape of cutting edge complexity, cutting tip blade size cannot effectively ensure, the more difficult control of product size uniformity, the cutting ability of blade is unstable.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provides a kind of and be convenient to the making of mould, compressing convenience, cutting tip that cutting ability is stable.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of cutting tip, comprise the blade body in polygon tabular, described blade body is surrounded by multiple sides of upper surface, lower surface and connection upper and lower surface, described upper surface and side one_to_one corresponding, between described side and upper surface, angle is acute angle, and at least one side and upper surface intersect formation continuous cutting sword, on upper surface direction, described continuous cutting sword is linearly, in the lateral direction, and described continuous cutting sword concave-convex surface.
Described continuous cutting sword is alternately formed by connecting by multiple protuberance and recess.
Described continuous cutting sword has M recess, wherein 1≤M≤8.
Described blade body is provided with the centre bore running through upper surface and lower surface.
Compared with prior art, the invention has the advantages that:
Cutting tip of the present invention, the shape of continuous cutting sword on upper surface direction is linear pattern, greatly reduce making and the detection difficulty of mould, effectively can improve the quality of fit of cutting tip related die, thus effectively eliminate burr and the pressure check of cutting tip cutting edge in compacting, improve product percent of pass.In addition, the cutting edge of cutting tip is linear pattern blade type on upper surface direction, and bite place Blade dimensions can effectively detect, thus ensures cutting tip dimensional uniformity, makes cutting tip stable performance.Continuous cutting sword is alternately formed by connecting by multiple protuberance and recess, participates in cutting when protuberance is different from recess, and what can alleviate the impact of continuous cutting sword, reduce cutting force thus make cutting tip has higher cutting ability.

Detailed description of the invention
Fig. 4 to Fig. 6 shows a kind of cutting tip of the present invention, comprise the blade body 1 in polygon tabular, blade body 1 is by upper surface 2, multiple sides 4 of lower surface 3 and connection upper and lower surface surround, upper surface 2 and side 4 one_to_one corresponding, between side 4 and upper surface 2, angle is acute angle, in the present embodiment, relief angle equals 7 °, at least one side 4 and upper surface 2 intersect formation continuous cutting sword 6, from a side 4 to another side corresponding thereto, continuous cutting sword 6 concave-convex surface, look down from upper surface 2 direction, continuous cutting sword 6 is linearly, thus making and the detection difficulty of mould can be reduced greatly, effectively can improve the quality of fit of cutting tip related die, eliminate burr and the pressure check of cutting tip cutting edge in compacting, improve product percent of pass, in addition, continuous cutting sword 6 is linearly on upper surface 2 direction, and Blade dimensions can effectively be detected, thus ensures cutting tip dimensional uniformity, makes cutting tip stable performance.
In the present embodiment, continuous cutting sword 6 is alternately formed by connecting with recess 8 by multiple protuberance 7, participates in cutting when protuberance 7 is different from recess 8, can alleviate the impact of continuous cutting sword 6, reduces cutting force thus make cutting tip have higher cutting ability.Continuous cutting sword 6 has M recess 8, wherein 1≤M≤8, in the present embodiment, and M=2.Blade body 1 is also provided with the centre bore 5 running through upper surface 2 and lower surface 3, blade body 1 is fixed on tool rest for mounting fastener by centre bore 5.
Above-mentioned just preferred embodiment of the present invention, not does any pro forma restriction to the present invention.Although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention.Any those of ordinary skill in the art, when not departing from technical solution of the present invention scope, can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solution of the present invention, or being revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to the technology of the present invention essence to any simple modification made for any of the above embodiments, equivalent variations and modification, all should drop in the scope of technical solution of the present invention protection.
