Description
Technical field
A kind of new drill is the utility model is related to, belongs to bit technique field.
Background technology
Drill bit be on solid material drilling go out through hole or blind hole, and can be to the cutter of existing hole reaming.It is common
Drill bit mainly have fluted drill, chit drill, centre drill, depth drill and cylindrical drill etc..Including high-speed steel drill, carbide drill,
Tungsten bur；Cut depth：35MM, 50MM or 100mm；Specification：12MM to 100MM;Drill bit；Main material has high-speed steel class；
Powder metallurgy class；Hard alloy class.It is adapted to motor：Magnetic drill/magnetic drill press/drilling machine/lathe/milling machine, it is species, complete in specifications,
Suitable for the import magnetic drill press of various brands（Magnetic drill）And general drilling machine, milling machine, boring machine etc..
Using common drill bit when being processed axial workpiece, concentric shafts and one of them vertical position with concentric shafts
, it is necessary to drill at another position vertically with concentric shafts, normal drill bit processes another and hangs down after progress Drilling operation
Three problems directly occur during hole with the position of concentric shafts：1st, hole drill is inclined；2nd, circular iron is remained in concentric axis hole to cut, by
Small in concentric shaft size can be difficult to exclude；3rd, this hole and concentric shafts intersection have more burr.
The content of the invention
In view of this, the utility model provides a kind of new drill, can prevent that hole drill is inclined, avoid in concentric axis hole
The circular iron of residual is cut, and prevents that drilling intersection is jagged.
The utility model solves above-mentioned technical problem by following technological means：
A kind of new drill of the utility model, it includes handle of a knife and cutter head, and the front end of cutter head is provided with circular arc cutting edge, knife
At least one of chip space is provided with head, knife spine is provided between adjacent twice chip space, is provided with the circular arc cutting edge interior
Cold hole, handle of a knife and cutter head are integrally formed.
The chip space is helical structure, and chip space is arranged on cutter head perisporium, and knife spine is helical structure, and knife
The back of the body is arranged on cutter head perisporium, and the cross section of chip space is arcuate structure, and the cross section of knife spine is pyramidal structure.
The circular arc cutting edge is arranged on knife spine top, is arc structure.
The material of drill bit is hard alloy.
The utility model in actual use, using circular arc cutting edge, compared to more common drill bit, chip that when drilling obtains
Expect more refinement, and be in powdered substantially, can be discharged from chip space, powdered material fluidity is more preferable, it is easier to discharge, and circle
Interior cold hole is provided with arc cutting edge, can effectively cool down drill bit, reduces heating caused by friction, and due to circular arc cutting edge, bore
Head and the contact surface of object to be processed are relatively smooth face, avoid the generation of burr, and due to chip material be it is powdered,
It is thinner, it is not easy to be remained in concentric axis hole.
The beneficial effects of the utility model：It can prevent that hole drill is inclined, avoid the circular iron of residual in concentric axis hole from cutting, prevent
Drilling intersection is jagged.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of workpiece to be added
1st, circular arc cutting edge；2nd, interior cold hole；3rd, knife spine；4th, row cuts groove；5th, handle of a knife；6th, cutter head.
Embodiment
The utility model is described in detail below with reference to attached drawing, as shown in Figure 1：A kind of Novel drill of the present embodiment
Head, it includes handle of a knife 5 and cutter head 6, and the front end of cutter head 6 is provided with circular arc cutting edge 1, at least one of chip space is provided with cutter head 7
4, knife spine 3 is provided between adjacent twice chip space 4, interior cold hole 2 is provided with the circular arc cutting edge 1, handle of a knife 5 and cutter head 6 are
It is integrally formed.
The chip space 4 is helical structure, and chip space 4 is arranged on 6 perisporium of cutter head, and knife spine 3 is helical structure,
And knife spine 3 is arranged on 6 perisporium of cutter head, the cross section of chip space 4 is arcuate structure, and the cross section of knife spine 3 is pyramidal structure.
The circular arc cutting edge 1 is arranged on 3 top of knife spine, is arc structure.
The material of drill bit is hard alloy.
As shown in Fig. 2, when processing this part, concentric axis hole D1 and vertically the drilling R with D1 first are processed with drill bit, so
After need to bore D2 holes at R, three problems occur in normal drill bit processing D2 holes：1st, hole drill is inclined；2nd, remained in D1 holes circular
Iron is cut, and can be difficult to exclude since D1 sizes are small；3rd, D2 and D1 intersections have more burr.
And the drill bit of the utility model is used, using circular arc cutting edge 1, compared to more common drill bit, what when drilling obtained cuts
Crumble more refinement, and be in powdered substantially, it can be discharged from chip space 4, powdered material fluidity is more preferable, it is easier to discharge,
And interior cold hole 2 is provided with circular arc cutting edge 1, drill bit can be effectively cooled down, reduces heating caused by friction, and due to Circular Nose Cutting Edge
Mouth 1, the contact surface of drill bit and object to be processed is relatively smooth face, avoids the generation of burr, and since chip material is
It is powdered, more carefully, it is not easy to remained in concentric axis hole.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, can be to this
The technical solution technical scheme is modified or replaced equivalently of utility model, without departing from the objective and model of technical solutions of the utility model
Enclose, it should all cover among the right of the utility model.
