Abstract
The utility model discloses a kind of carbon fibre composite aperture knife tool, comprise cutter hub, described cutter hub end face center has the center sword of band central angle alpha, cutter hub end face around center sword has the end sword at band oblique angle, cutter hub circumference has and crosses form the circumference sword of cutting edge with end sword, described center sword exceeds h0.5 ~ 1mm than end sword, and the relief angle β that circumference cutlery has is 10 ~ 20 °.Chisel edge owing to not having conventional drill such on cutter hub of the present utility model, therefore alleviates axial force during boring, is convenient to the lamination eliminating carbon fiber in process.Center sword serves good certralizing ability, to eliminate the beat phenomenon of drill bit, ensures the precision of hole machined shape.End sword crosses into sharp cutting edge with circumference sword, and drilling adds cuts fibrage man-hour, eliminates the phenomenon that carbon fiber is torn, and circumference sword can serve correcting action to hole simultaneously, ensure that the dimensional accuracy in hole.
Description
Technical field
The utility model relates to a kind of carbon fibre composite aperture knife tool.
Background technology
The composite that carbon fibre composite is take carbon fiber as reinforcing material, resin is matrix, because it has the advantages such as higher strength and stiffness, anti-fatigue performance is good, heat resistance is good, increasingly extensive in the application of aerospace field.Also just because of carbon fibre composite, there is the characteristics such as hardness is high, intensity large, poor thermal conductivity, interlaminar strength are low, belong to difficult-to-machine material.Use common high-speed steel drill to add man-hour in the enterprising perform hole of carbon fibre composite, the defect such as very easily occur material burn, of poor quality, the layering of hole surface, tear, thus cause scrapping of workpiece made of carbon fiber composite.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of and can guarantee hole machined precision, eliminates carbon fiber and tear the carbon fibre composite aperture knife tool of phenomenon.
The utility model solves the technical scheme that its technical problem adopts: a kind of carbon fibre composite aperture knife tool, comprise cutter hub, described cutter hub end face center has the center sword of band central angle alpha, cutter hub end face around center sword has the end sword at band oblique angle, cutter hub circumference has and crosses form the circumference sword of cutting edge with end sword, described center sword exceeds h0.5 ~ 1mm than end sword, and the relief angle β that circumference cutlery has is 10 ~ 20 °.
Preferably, the central angle alpha that described center cutlery has is 90 °.
For improving cutter wearability, described cutter hub material is W-Co kind carbide alloy,
Further, described center sword exceeds h0.5mm than end sword, and the relief angle β that circumference cutlery has is 20 °.
The beneficial effects of the utility model are: the chisel edge owing to not having conventional drill such on cutter hub of the present utility model, therefore alleviate axial force during boring, are convenient to the lamination eliminating carbon fiber in process.First center sword serves good certralizing ability adding man-hour, to eliminate the beat phenomenon of drill bit, ensures the precision of hole machined shape.End sword crosses into sharp cutting edge with circumference sword, and drilling adds and circles man-hour, cuts fibrage, eliminates the phenomenon that carbon fiber is torn, and circumference sword can serve correcting action to hole simultaneously, ensure that the dimensional accuracy in hole.

Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of carbon fibre composite aperture knife tool as shown in Figure 1 and Figure 2, comprise cutter hub 1, cutter hub 1 the selection of material is that W-Co kind carbide alloy makes, described cutter hub 1 end face center has the center sword 2 that central angle alpha is 90 °, cutter hub 1 end face around center sword 2 has the end sword 3 at band oblique angle, cutter hub 1 circumference has and crosses forms the circumference sword 4 of cutting edge with end sword 3, and the relief angle β that circumference sword 4 has is 20 °, and described center sword 2 exceeds h0.5mm than holding sword 3.
The utility model selects W-Co kind carbide alloy to make, and improves the wearability of cutter entirety.Chisel edge owing to not having conventional drill such on cutter hub 1, alleviates axial force during boring, eliminates the lamination of carbon fiber in process.Center sword 2 adds and first plays certralizing ability man-hour, to eliminate the beat phenomenon of drill bit, ensures the precision of hole machined shape.End sword 3 crosses into sharp cutting edge with circumference sword 4, and drilling adds and circles man-hour, cuts fibrage, eliminates the phenomenon that carbon fiber is torn, and circumference sword 4 serves correcting action simultaneously, ensure that the dimensional accuracy in hole.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
