Description

Cutting tip

Technical field

The utility model relates to the cutting tip with continuous cutting blade, relates in particular to the cutting tip with concavo-convex cutting edge.

Background technology

It has been found that in the cut, concavo-convex cutting edge is when the incision workpiece; Its concavo-convex cutting edge is not to cut simultaneously, and concavo-convex cutting edge contacts with workpiece gradually, can relax impact fully, reduce cutting force; Simultaneously, it is more broken to have a smear metal that the blade incision workpiece of concavo-convex cutting blade structure produces, in the working angles; Less smear metal can be fast, easily discharge, effectively avoid smear metal scratch finished surface.Has the above characteristic owing to have the blade of concaveconvex structure cutting edge, so this type of blade is widely used in the metal processing.This type of cutting tip is general to be adopted like Fig. 1 to structure shown in Figure 3; Blade body 1 is surrounded by a plurality of sides 4 of upper surface 2, lower surface 3 and connection upper and lower surfaces; Upper surface 2 is corresponding one by one with side 4; Have one or more sides 4 to intersect with upper surface 2 and form continuous cutting edge 6, on upper surface 2 and side 4 directions, cutting edge 6 all has concavo-convex cutting blade structure continuously.

Though this structure cutting tip has advantage as stated; But the cutting tip that all has concavo-convex cutting edge on upper surface and the side surface direction, its cutting blade is comparatively complicated, and the mould and die accuracy of blade is difficult to guarantee, the press forming difficulty; And crackle appears in product easily that suppress, and qualification rate is low; In addition because the complicated shape of cutting edge, cutting tip the blade size can't effectively guarantee, the difficult control of product size uniformity, the cutting ability of blade is unstable.

The utility model content

The technical problem that the utility model will solve is the deficiency that overcomes prior art, and a kind of making of mould, cutting tip that compression moulding is convenient, cutting ability is stable be convenient to is provided.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of cutting tip comprises being the tabular blade body of polygon, and said blade body is surrounded by a plurality of sides of upper surface, lower surface and connection upper and lower surfaces; Said upper surface is corresponding one by one with the side, and angle is an acute angle between said side and the upper surface, and at least one side and upper surface intersect the continuous cutting edge of formation; On the upper surface direction; Said continuous cutting edge is shape linearly, on side surface direction, and said continuous cutting edge concave-convex surface.

Said continuous cutting edge alternately is formed by connecting a plurality of protuberances and recess.

Said continuous cutting edge has M recess, wherein 1≤M≤8.

Said blade body is provided with the centre bore that runs through upper surface and lower surface.

Compared with prior art, the advantage of the utility model is:

The cutting tip of the utility model; Continuously cutting edge is shaped as linear pattern on the upper surface direction; Greatly reduce the making and the detection difficulty of mould; Can effectively improve the quality of fit of cutting tip related die, thereby effectively eliminate the burr and the pressure check of cutting tip cutting edge in the compacting, improve product percent of pass.In addition, the cutting edge of cutting tip is linear pattern sword type on the upper surface direction, and bite place cutting edge size can effectively detect, thereby guarantees the cutting tip dimensional uniformity, makes the cutting tip stable performance.Cutting edge alternately is formed by connecting a plurality of protuberances and recess continuously, and protuberance and recess are not participated in cutting simultaneously, thereby impact, the reduction cutting force that can alleviate continuous cutting edge make the higher cutting ability of having of cutting tip.

The specific embodiment

Fig. 4 to Fig. 6 shows a kind of cutting tip of the utility model, comprises being the tabular blade body of polygon 1, and blade body 1 is surrounded by a plurality of sides 4 of upper surface 2, lower surface 3 and connection upper and lower surfaces; Upper surface 2 is corresponding one by one with side 4, and angle is an acute angle between side 4 and the upper surface 2, and relief angle equals 7 ° in the present embodiment; The continuous cutting edge 6 of formation is intersected with upper surface 2 at least one side 4, sees to the another side relative with it from a side 4, continuously cutting edge 6 concave-convex surfaces; Be directed downwards from upper surface 2 and see; Continuous cutting edge 6 is shape linearly, thereby can reduce the making and the detection difficulty of mould greatly, can effectively improve the quality of fit of cutting tip related die; Eliminate the burr and the pressure check of cutting tip cutting edge in the compacting, improve product percent of pass; In addition, continuously cutting edge 6 shape linearly on upper surface 2 directions can effectively detect the cutting edge size, thereby guarantees the cutting tip dimensional uniformity, makes the cutting tip stable performance.

In the present embodiment, continuous cutting edge 6 alternately is formed by connecting with recess 8 a plurality of protuberances 7, and protuberance 7 is not participated in cutting simultaneously with recess 8, thereby impact, the reduction cutting force that can alleviate continuous cutting edge 6 make cutting tip have higher cutting ability.Continuously cutting edge 6 has M recess 8,1≤M≤8 wherein, and in the present embodiment, M=2.Also be provided with the centre bore 5 that runs through upper surface 2 and lower surface 3 on the blade body 1, centre bore 5 is used to install securing member blade body 1 is fixed on tool rest.

The above-mentioned just preferred embodiment of the utility model is not that the utility model is done any pro forma restriction.Though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model.Any those of ordinary skill in the art; Under the situation that does not break away from the utility model technical scheme scope; All the technology contents of above-mentioned announcement capable of using is made many possible changes and modification to the utility model technical scheme, or is revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not break away from the utility model technical scheme, all should drop in the scope of the utility model technical scheme protection any simple modification, equivalent variations and modification that above embodiment did according to the utility model technical spirit.
