Abstract

The utility model provides a chamfering cutter, including blade disc and handle of a knife, the handle of a knife sets firmly on the axial lead at blade disc middle part, evenly seted up 6 edges of a knife on the blade disc, every alpha plane and beta plane that the edge of a knife is mutually perpendicular form, the axial lead at blade disc middle part contains in the alpha plane, the rigid coupling has the diamond and forms the cutting edge on the alpha plane, 2.5mm's chamfer is seted up to the top face of blade disc. The utility model discloses chamfering cutter passes through 6 edges of a knife of uniform design on the blade disc and weld the diamond on the edge of a knife to form the cutting edge, and when processing cell -phone housing face's edges and corners, the piece of production can in time be followed the cutting edge and fallen down, can not lead to the jam of chamfering cutter cutting edge and influence the processing process of cell -phone casing, the work efficiency height.

Description

A kind of rose reamer

Technical field

The utility model relates to a kind of cutter, particularly relates to a kind of rose reamer.

Background technology

Rose reamer is the cutter in order to the chamfering of processing work, taper hole and surface of the work reverse mould corner angle, and particularly, rose reamer is used for the chamfering of processing mobile phone housing or corner angle profile.Current rose reamer is when the corner angle of processing mobile phone surface of shell, and the chip of generation drops on the blade of rose reamer, and causing the blade of rose reamer to block and incur loss through delay handset shell is machine process, reduces operating efficiency.

Summary of the invention

In view of the above, the utility model is necessary the rose reamer that provides a kind of operating efficiency high.

The technical scheme that the utility model provides is as follows: a kind of rose reamer, comprise cutterhead and handle of a knife, described handle of a knife is installed on the axial line in the middle part of cutterhead, described cutterhead evenly offers 6 edges of a knife, each described edge of a knife is that orthogonal α plane and β plane are formed, axial line in the middle part of described cutterhead is contained in α plane, described α plane is connected with diamond and forms blade, and the top end face of described cutterhead offers the chamfering of 2.5mm.

Further, the thickness of described cutterhead is 9mm, diameter is 25mm.

Further, the length of described handle of a knife is 24mm, diameter is 10mm.

Further, the rounding of 4mm is offered inside described diamond.

Further, described diamond welding is in α plane.

Compared with prior art, the utility model rose reamer passes through 6 edges of a knife of uniform Design on cutterhead and on the edge of a knife, welds diamond formation blade, during the corner angle of processing mobile phone surface of shell, the chip produced can fall from blade in time, rose reamer blade can not be caused to block and affect the machine process of handset shell, operating efficiency is high.

Accompanying drawing explanation

Fig. 1 is the front view of the utility model rose reamer;

Fig. 2 is the side view of the utility model rose reamer.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually, below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.

Refer to shown in Fig. 1, a kind of rose reamer, comprise cutterhead 10 and handle of a knife 20, handle of a knife 20 is installed on the axial line in the middle part of cutterhead 10.

The thickness of cutterhead 10 is 9mm, diameter is 25mm, the top end face of cutterhead 10 offers the chamfering of 2.5mm, refer to Fig. 2, cutterhead 10 evenly offers 6 edges of a knife 11, each described edge of a knife 11 is formed for orthogonal α plane 111 and β plane 112, and the axial line in the middle part of cutterhead 10 is contained in α plane 111, α plane 111 be connected with diamond 12 and form blade, further, diamond 12 is welded in α plane 111, offers the rounding of 4mm inside diamond 12.

Adopt adamantine benefit: 1. adamantine hardness can reach 8000HV, be 8-12 times of carbide alloy;

2. adamantine thermal conductivity factor is 700W/mK, and be 1.5-9 times of carbide alloy, even higher than PCBN and copper, therefore the transmission of diamond cutter heat is rapid;

3. adamantine coefficient of friction is generally only 0.1-0.3 (coefficient of friction of carbide alloy is 0.4-1), and therefore diamond cutter significantly can reduce cutting force;

4. adamantine thermal coefficient of expansion is only 0.9 × 10 ^-6-1.18 × 10 ^-6, be only equivalent to 1/5 of carbide alloy, therefore diamond cutter thermal deformation is little, and machining accuracy is high;

5. diamond cutter and the affinity between non-ferrous metal and nonmetallic materials very little, in process, chip does not form built-up edge on point of a knife.

Handle of a knife 20 adopts carbon tool steel to make, and the length of handle of a knife 20 is 24mm, diameter is 10mm.

When the lead angle of rose reamer processing mobile phone surface of shell or profile corner angle, handset shell surface chamfering cutter cuts the chip produced and can fall from blade in time, and rose reamer blade can not be caused to block and affect the machine process of handset shell.

In sum, the utility model rose reamer passes through 6 edges of a knife of uniform Design on cutterhead and on the edge of a knife, welds diamond formation blade, during the corner angle of processing mobile phone surface of shell, the chip produced can fall from blade in time, rose reamer blade can not be caused to block and affect the machine process of handset shell, operating efficiency is high.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
