Description

A kind of PCD niblets reamer

Technical field

This practicality is newly related to a kind of machining tool, and in particular to a kind of good, the high in machining efficiency PCD of chip removal effect is beautiful Grain of rice reamer.

Background technology

In field of machining, reamer is the precision for improving machined hole, reduces the roughness on surface, existing Reamer is generally cutter head, handle of a knife Integral alloy is made, reprocess hard material when cutter head due to hardness it is not easy to wear enough, in addition The blade of existing reamer is typically all one-piece blade, and the bits band of generation is very wide to be not easy to be discharged, and causes to scratch when processing Finished surface, also to carry out it is secondary study for a second time courses one has flunked, it is time-consuming and laborious.

Utility model content

For overcome the deficiencies in the prior art, it adapts to reality to need, good, processing that the utility model is related to a kind of chip removal effects Efficient PCD niblet reamers

To achieve the goals above, the utility model adopts the following technical solution：Including shank portion and cutting tip, institute Cutting tip is stated to process there are three the chip space being equally spaced, respectively the first chip space, the second chip space and third chip space, The end face of first chip space is equipped with blade one, blade two, blade three, the end face of second chip space be equipped with blade four, The end face of blade five, blade six, the third chip space is equipped with blade seven, blade eight, has certain distance between each blade It separates, set of blades on each chip space is side set sequence distribution, the vacancy between complete complementary cutting edge, to reach To a complete effective machining sword, aluminium skimmings that when milling generates narrow from the width more easily chip breaking, and the blade is all It is made of PCD material, hardness is big, and cutting hardness is high, and the angle of the chip space end face and axial plane is 5-10 °, makes blade Negative rake is formed, keeps cutting edge sharper, cutting resistance is substantially reduced when coming into contact in a large area milling, to reduce milling Vibrations, workpiece surface have obtained better finish.

The beneficial effects of the utility model are：The cutting edge of cutting tip mutually staggers arrangement, can reach and completely cut Cut effect, moreover it is possible to keep bits band narrow by broadside, chip removal effect is more preferable, and it is sharper that the design of blade negative rake makes to cut inclined edge, reduces Cutting resistance improves the larger workpiece of the blade energy workhardness of processing efficiency PCD materials, the range of work is made to increase.

Description of the drawings

Fig. 1 is the side view of the utility model；

Fig. 2 is the cutting tip vertical view of the utility model；

Fig. 3 is the set of blades arrangement figure of the first chip space；

Fig. 4 is the set of blades arrangement figure of the second chip space；

Fig. 5 is the set of blades arrangement figure of third chip space；

In figure：1 shank portion, 2 cutting tips, 3 first chip spaces, 4 second chip spaces, 5 third chip spaces, 6 blades one, 7 blades two, 8 blades three, 9 blades four, 10 blades five, 11 blades six, 12 blades seven, 13 blades eight.

Specific implementation mode

Embodiment：A kind of PCD niblets reamer, with reference to body Fig. 1 to Fig. 5, including shank section, 1 and cutting tip 2, it is described There are three the chip space being equally spaced, respectively the first chip space 3, the second chip space 4 and third chip spaces for cutting tip processing 5, the end face of first chip space is equipped with blade 1, blade 27, blade 38, and the end face of second chip space is equipped with knife Piece 49, blade 5 10, blade 6 11, the end face of the third chip space are equipped with blade 7 12, blade 8 13, each blade it Between there is certain distance to separate, set of blades on each chip space is side set sequence distribution, complete complementary cutting edge it Between vacancy, to reach a complete effective machining sword, aluminium skimmings that when milling generates, which narrow from the width, more easily breaks Bits, the blade are all made of PCD material, and hardness is big, and cutting hardness is high, the angle of the chip space end face and axial plane It is 5-10 °, so that blade is formed negative rake, keep cutting edge sharper, cutting resistance is substantially reduced when coming into contact in a large area milling Power, to reduce milling vibrations, workpiece surface has obtained better finish.

It should be noted that the detail of cutting edge complementation is：

Blade 1 fills up the gap between blade 49 and blade 5 10, blade 5 10 fill up blade 1 and blade 27 it Between gap, blade 7 12 all fills up in above-mentioned two gap；

Blade 6 11 fills up the gap between blade 27 and blade 38, and blade 27 fills up blade 5 10 and blade 11 6 Between gap, blade 8 13 all fills up in above-mentioned two gap；

The side set sequence as niblet of all blades is distributed in cutting end, is equivalent to integral knife blade dispersion cutting is mutual Complementation, generated cutting swarf narrows when compared to more integrated blade cut, and chip removal effect is more preferable.

Above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple Other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope should all cover in the right of the utility model.
