Description

A kind of arc cutter
Technical field
The utility model belongs to mobile phone center process equipment, and in particular to a kind of arc cutter.
Background technology
As smart mobile phone develops to high-performance, harsh appearance design direction, increasing mobile phone center uses aluminium Alloy designs.Under the complexity of mobile phone producer CNC processing mobile phone circular arcs and the high request to crudy, using common hard Matter alloy milling cutter carries out CNC Milling Process, is unable to reach the complex-curved arc size of mobile phone center and harsh appearance requirement, and And cutter life is low, frequent shutdown changes hard alloy cutter in process, causes that lathe downtime is long, is produced into This increase;Cutter consumption is big, a large amount of uses of carbide-tipped milling cutter, and it is huge consumption to non-renewable tungsten ore to be, no Beneficial to sustainable development, it is unfavorable for environment-friendly and green production.
Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art, to be suitable to the processing of mobile phone center, longevity so as to provide one kind Order long arc cutter.
To achieve these goals, technical scheme is used by the utility model:
A kind of arc cutter, including handle of a knife, cutter head, cutter tooth and chip area, some blades are provided with the cutter tooth, it is described The cutting edge of blade is located at the cutter head sidepiece and is in arcs of recesses, and the cutter tooth includes the concave arc-shaped section that the corresponding blade shape is set Seamlessly transitted with from the concave arc-shaped section to the convex ridge section of the handle of a knife.
Based on above-mentioned, the blade is fixed and is fitted in the side wall of the concave arc-shaped section.
Based on above-mentioned, the height of the cutting edge is more than the height of the concave arc-shaped section.
Based on above-mentioned, the blade is polycrystalline diamond blade.
Based on above-mentioned, glomerocryst of the blade including hard alloy substrate and the surface for being coated on the hard alloy substrate Buddha's warrior attendant stone layer.
Based on above-mentioned, the handle of a knife is straight type handle of a knife.
Based on above-mentioned arc cutter, it includes 4 chip areas, and the angle of the two side of each chip area is in 90 degree.
The utility model has substantive distinguishing features and progress compared with the prior art, specifically, the utility model have with Lower advantage:
The utility model provides a kind of arc cutter, including handle of a knife, cutter head, cutter tooth and chip area, is set on the cutter tooth There are some blades, the cutting edge of the blade is located at the cutter head sidepiece and is in arcs of recesses, and the cutter tooth includes the corresponding cutting edge The concave arc-shaped section and seamlessly transitted from the concave arc-shaped section to the convex ridge section of the handle of a knife that shape is set;So that the arc cutter is applied to The processing of mobile phone center arc size, the blade, can be effective for polycrystalline diamond blade or including the polycrystalline diamond bed of material The service life of the arc cutter is improved, is had broad application prospects.
Brief description of the drawings
Fig. 1 is the structural representation of arc cutter in the utility model.
In figure:1. handle of a knife;2. convex ridge section;3. concave arc-shaped section;4. blade;5. chip area.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in figure 1, a kind of arc cutter, including handle of a knife 1, cutter head, cutter tooth and chip area 5, it is provided with the cutter tooth Some blades 4, the cutting edge of the blade 4 are located at the cutter head sidepiece and are in arcs of recesses, and the cutter tooth includes the corresponding cutting edge The concave arc-shaped section 3 and seamlessly transitted from the concave arc-shaped section 3 to the convex ridge section 2 of the handle of a knife 1 that shape is set, the blade 4, which is fixed, to be pasted Close in the side wall of the concave arc-shaped section 3, the height of the cutting edge is more than the height of the concave arc-shaped section 3 so that the arc cutter is fitted For the processing of mobile phone center arc size, the tool damage in processing is avoided.
Specifically, the arc cutter includes 4 chip areas 5, and the angle of the two side of each chip area 5 is in 90 degree.
Specifically, in order to improve the service life of the arc cutter, the blade 4 is for polycrystalline diamond blade or including hard Matter alloy substrate and be coated on the hard alloy substrate surface the polycrystalline diamond bed of material blade.
Finally it should be noted that:Above example is only illustrating the technical solution of the utility model rather than it is limited System;Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should Understand:Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced Change;Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model Among scope.
