Abstract
The invention relates to a drilling tool, in particular to an automobile die chamfer bit comprising a bit body. The bit body comprises a shank and a chamfering head. The chamfering head is in the shape of a cone frustum. The shank is fixedly connected with a large diameter end of the chamfering head. The side of the cone frustum of the chamfering head is sleeved with a polishing tube. The outer surface of the polishing tube is an abrasive surface or edged surface. The shank is cylindrical or conical. The chamfer bit has the advantages that when the chamfer bit is used with an electric or manual tool, the cone frustum design of the chamfering head allows the chamfer bit to adapt to different hole diameters and the troubles of frequently changing the bit are decreased; in addition, the application of the polishing tube as a sleeve allows for convenient replacement after wearing; the alternative use of the abrasive surface and the edged surface allows selections to be conveniently made for different chamfering requirements.
Description
Technical field
The present invention relates to boring bar tool, relate in particular to a kind of automobile die chmfer bit.
Background technology
The corner of automobile die and circular hole all need chamfering, and the circular hole chamfering of less mould adopts drilling machine conventionally, and because the most of volume of automobile die is larger, if by drilling machine chamfering, carry inconvenience.Therefore often need to carry out chamfering operation by handheld tool at the scene, if but adopt the common drill bit chamfering not only will be according to frequently bit change more of different pore size, troublesome poeration, and fillet surface is also undesirable.Especially partially boring is more easily appearred in some oblique side openings, affect product processing quality.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of automobile die chmfer bit is provided.Can be to the circular hole chamfering handled easily whenever and wherever possible of automotive-type mould.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: comprise drill body, it is characterized in that, described drill body comprises drillstock and chamfering head, described chamfering head is truncated cone-shaped, described drillstock is fixedly connected with the larger diameter end of described chamfering head, and the frustum cone side of described chamfering head is set with polishing cylinder.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the outer surface of described polishing cylinder is frosting or blade face.
Further, described drillstock is cylindrical or conical.
The invention has the beneficial effects as follows: in the time that drill bit distribution of the present invention is moving or hand-operated tools uses, due to the truncated cone-shaped design of chamfering head, can takes into account different pore size and use, reduce the trouble of frequent bit change; Owing to adopting overcoat polishing cylinder, after convenient wearing and tearing, change in addition; Adopt frosting and two kinds of selection forms of blade face, facilitated the selection requiring for different chamferings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is frosting chamfering barrel structure schematic diagram of the present invention;
Fig. 3 is cutting edge surface chamfer barrel structure schematic diagram of the present invention.
At Fig. 1 in Fig. 3,1, drillstock; 2, chamfering head; 3, polishing cylinder; 4, blade face; 5, frosting.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
If Fig. 1 is to as shown in Fig. 3, a kind of automobile die chmfer bit, comprises drill body, described drill body comprises drillstock 1 and chamfering 2, described chamfering 2 is truncated cone-shaped, and the larger diameter end of described drillstock 1 and described chamfering 2 is fixedly connected with, and the frustum cone side of described chamfering 1 is set with polishing cylinder 3.The combination of chamfering head and polishing cylinder can adopt interior external splines form suit, and easy disassembly is changed.
The outer surface of described polishing cylinder 3 is frosting 5 or blade face 4.Described frosting 5 can be one deck sand paper of pasting on polishing cylinder 3 surfaces.
Described drillstock 1 is cylindrical or conical.
Drill bit of the present invention can directly coordinate electric hand drill, pneumatic tool or hand drill to use, especially chamfering accurate positioning, the convenience to oblique side opening.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (3)
1. an automobile die chmfer bit, comprises drill body, it is characterized in that, described drill body comprises drillstock and chamfering head, described chamfering head is truncated cone-shaped, and described drillstock is fixedly connected with the larger diameter end of described chamfering head, and the frustum cone side of described chamfering head is set with polishing cylinder.
2. automobile die circular hole chmfer bit according to claim 1, is characterized in that, the outer surface of described polishing cylinder is frosting or blade face.
