On the basis of technique scheme, comprise attached technical scheme further:
Described blade comprises front cutting edge, the rake face tilting to be connected with front cutting edge, the main cutting edge be connected with rake face, the major first flank be connected with main cutting edge, be connected with main cutting edge second after knife face, the circular arc chamfered edge be connected with front cutting edge and the minor flank be all connected with knife face after circular arc chamfered edge and second.
The width of described blade is less than the width of chip area, and blade is circumferentially being positioned at outside the periphery of toothed projections place at least partly, and is also partly positioned at outside the end face of toothed projections place in the axial direction.
Described main cutting edge is less than the area of front cutting edge, and is greater than the area of rake face, and major first flank is between rake face, circular arc chamfered edge, the second rear knife face three.
Described front cutting edge is that horizontal direction is arranged, and main cutting edge is vertical direction setting, and major first flank is positioned at the top of knife face after second.
Described blade is carbide chip or ceramic tip or polycrystalline diamond blade or cubic boron nitride blade.
The utility model advantage is:
The utility model is by Curve guide impeller of the present utility model, straight fluted reamer can be made to have function to front clearance, thus avoid cutting scuffing machined surface, improve crudy and efficiency, applied widely, as whole hard alloy straight fluted reamer, high-speed steel straight fluted reamer, welding carbide alloy straight fluted reamer, weld all kinds of superhard material straight fluted reamer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the schematic perspective view of the first embodiment of the present utility model;
Fig. 2 is that the partial enlarged drawing of cutting portion in Fig. 1 looks schematic diagram;
Fig. 3 is the partial sectional view in Fig. 2;
Fig. 4 is the front view of the second embodiment of the present utility model.
Detailed description of the invention
As Figure 1-3, the utility model provides a kind of first embodiment with the reamer of cutting portion, the knife bar portion 2 that it comprises shank section 1, one end is connected with shank section 1 and the cutting portion 3 be weldingly connected with the other end in knife bar portion 2, wherein cutting portion 3 comprise axle center 30, centered by axle center 30 and the circle spacing arrangement several toothed projections 32, be arranged on the blade 34 of corresponding toothed projections 32 side and several chip areas 36 between toothed projections 32.Wherein the width of blade 34 is less than the width of chip area 36, and blade 34 is circumferentially being positioned at outside the periphery of toothed projections 32 place at least partly, and is also partly positioned at outside the end face of toothed projections 32 place in the axial direction.
Blade 34 comprises front cutting edge 300, the rake face 310 tilting to be connected with front cutting edge 300, the main cutting edge 320 be connected with rake face 310, the major first flank 322 be connected with main cutting edge 320, knife face 324 after be connected with main cutting edge 320 second, the circular arc chamfered edge 301 be connected with front cutting edge 300, the minor flank 302 be all connected with knife face 324 after circular arc chamfered edge 301 and second, the area of main cutting edge 320 is less than the area of front cutting edge 30, and be greater than the area of rake face 310, major first flank 322 is positioned at rake face 310, circular arc chamfered edge 301, after second between knife face 324 three.From Fig. 2, front cutting edge 300 is horizontal direction setting, main cutting edge 320 is vertical direction setting, major first flank 322 is positioned at the top of knife face 324 after second, be understandable that the description in this direction is only the description to Fig. 2, and helping those skilled in the art to understand, its direction also can be different according to the placement difference of product, can not limit scope of the present utility model with this.The angle of rake face 310 for turning forward of main cutting edge 320 thus, the anterior angle of such main cutting edge 320 is just formed as negative rake, and cutting pushes away forward when chip produces by this negative rake turned forward.Thus realize cutting the function to front row, protect the scuffing that hole surface is not cut.Blade 34 material can be carbide chip or ceramic tip or PCD (polycrystalline diamond) blade or CBN (cubic boron nitride) blade, and can carry out low temperature PVD (physical deposition coating) to blade.
As shown in Figure 4, the utility model provides a kind of second embodiment with the reamer of cutting portion, the knife bar portion 2 that it comprises shank section 1, one end is connected with shank section 1 and the cutting portion 4 be connected with the other end one in knife bar portion 2, the wherein structure of cutting portion 4 and the similar of cutting portion 3, its axial length will be grown relatively.
The utility model is by Curve guide impeller of the present utility model, straight fluted reamer can be made to have function to front clearance, thus avoid cutting scuffing machined surface, improve crudy and efficiency, applied widely, as whole hard alloy straight fluted reamer, high-speed steel straight fluted reamer, welding carbide alloy straight fluted reamer, weld all kinds of superhard material straight fluted reamer.
Certain above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
