Deng.Wherein cotter mill cutter is mainly used in the keyway processing of part.A kind of therefore, it is proposed that carbide key way mill.
Utility model content
The purpose of this utility model is to provide a kind of carbide key way mill, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of carbide key way mill, including knife
Body, it is characterised in that：The front end of the cutter hub is provided with two cutter heads, and the one end of the cutter hub away from cutter head is fixedly connected with knife
Handle, the handle of a knife are provided with annular groove on one end outer wall of cutter hub, and strip slot, and knife are symmetrically provided with the outer wall of the cutter hub
Spiral groove is provided with the outer wall of body, the strip slot connection spiral groove and annular groove, the cutter head, cutter hub and handle of a knife are one
Body structure；
Two cutter heads are symmetrical arranged on the axle center of cutter hub, and cutter head is curved, and the cutter head is close to cutter hub axle center
The height of one end is more than its height away from cutter hub axle center one end.
Preferably, the depth of the spiral groove is not more than the depth of strip slot.
Preferably, the depth of the strip slot and the depth of annular groove are consistent, and the section of strip slot is curved.
Preferably, the length of the strip slot is consistent with cutter hub length.
Preferably, the section of the cutter head is triangular in shape.
Compared with prior art, the beneficial effects of the utility model are：This milling cutter has the characteristics of being not easily broken；Cutter hub is only
Surface is slotted, and its inside has larger bearing part, hence in so that cutter hub is not easily broken；One end outer wall of the handle of a knife close to cutter hub
On be provided with annular groove, make this milling cutter go out to consider to be worth doing when processing deeper keyway it is smooth；Strip slot and spiral are provided with the outer wall of cutter hub
Shape groove, the keyway cell wall for both processing this milling cutter is smooth, is advantageous to the radiating of cutter hub again, extends the service life of this milling cutter.
Brief description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model left view；
Fig. 3 is Fig. 2 Section A-A figure.
Label in figure：1 cutter hub, 2 cutter heads, 3 handle of a knifes, 4 annular grooves, 5 strip slots, 6 spiral grooves.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of carbide key way mill, including cutter hub
1, the front end of the cutter hub 1 is provided with two cutter heads 2, and the section of the cutter head 2 is triangular in shape, and the cutter hub 1 is away from cutter head 2
One end is fixedly connected with handle of a knife 3, and the handle of a knife 3 is provided with annular groove 4, the outer wall of the cutter hub 1 on one end outer wall of cutter hub 1
On be symmetrically provided with strip slot 5, and spiral groove 6 is provided with the outer wall of cutter hub 1, the strip slot 5 connects spiral groove 6 and annular
Groove 4, the cutter head 2, cutter hub 1 and handle of a knife 3 are structure as a whole.
Two cutter heads 2 are symmetrical arranged on the axle center of cutter hub 1, and cutter head 2 is curved, and the cutter head 2 is close to cutter hub 1
The height of axle center one end is more than its height away from the axle center one end of cutter hub 1.
The depth of the spiral groove 6 is not more than the depth of strip slot 5, the depth of the strip slot 5 and the depth of annular groove 4
Degree is consistent, and the section of strip slot 5 is curved, and the length of the strip slot 5 is consistent with the length of cutter hub 1.
This milling cutter has the characteristics of being not easily broken；The only surface of cutter hub 1 is slotted, and its inside has larger bearing part, because
This causes cutter hub 1 to be not easily broken；Handle of a knife 3 is provided with annular groove 4 on one end outer wall of cutter hub 1, makes this milling cutter deeper in processing
