Abstract
The utility model discloses a kind of interior cold fluted drill of tangent plane at ladder, including auger spindle and drill main body, the drill main body is correspondingly arranged in the auger spindle side and is an integral structure setting, there are two cutting edges for the drill main body surface setting, the cutting edge helically structure setting on the mandrel of drill main body, and it is respectively corresponded between two cutting edges and is provided with chip space, drill main body end side is arranged in hierarchic structure, and the drill main body is also correspondingly arranged on the plane with axial angle on the cutting edge.The utility model structure is simple, and processing is easy to use, by plane of the partial application with axial angle at the ladder of cutting edge, increases the rigidity of cutting edge, prevents tipping phenomenon, promotes service life.
Description
Technical field
The utility model relates to be machined the interior cold fiber crops for using tangent plane at cutting tool field more particularly to a kind of ladder
Flower bores.
Background technique
For save the cost, processing beat is improved, the fluted drill of multi-ladder is often designed, it is therefore an objective to which a knife forms ladder
Hole.Encounter multistage ladder shell and the biggish fluted drill of groove profile swing angle angle, often causes because spiral angle is excessive in processing
Cutting edge is excessively sharp at ladder, and when processing will appear cutter tipping, phenomenon easy to wear.
Utility model content
It the purpose of this utility model is to provide a kind of structure is simple, processes easy to use, passes through the ladder in cutting edge
Locate plane of the partial application with axial angle, increases the rigidity of cutting edge, prevent tipping phenomenon, promoted and cut flat at the ladder of service life
The interior cold fluted drill in face.
The technical solution of the utility model is, the interior cold fluted drill of tangent plane at a kind of ladder, including auger spindle and drill bit master
Body, the drill main body are correspondingly arranged in the auger spindle side and are an integral structure setting, the drill main body surface setting
There are two cutting edge, helically structure setting is on the mandrel of drill main body for the cutting edge, and between two cutting edges respectively
It is correspondingly arranged on chip space, drill main body end side is arranged in hierarchic structure, and the drill main body is gone back on the cutting edge
It is correspondingly arranged on the plane with axial angle.
In one preferred embodiment of the utility model, the axial angle of the plane is 10 ° -15 °.
In one preferred embodiment of the utility model, the spiral angle of the cutting edge is 30 ° or 40 °.
In one preferred embodiment of the utility model, the drill main body end is provided with interior cold hole.
In one preferred embodiment of the utility model, the auger spindle end is provided with helical structure corresponding with interior cold hole
Interior cold trap.
Interior cold fluted drill described in the utility model for tangent plane at a kind of ladder, the utility model structure is simple, processing
It is easy to use, by plane of the partial application with axial angle at the ladder of cutting edge, increase the rigidity of cutting edge, prevents tipping existing
As promoting service life.
Detailed description of the invention
Fig. 1 is the front view at the utility model ladder in interior cold one preferred embodiment of fluted drill of tangent plane；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
The preferred embodiment of the utility model is described in detail below, so that the advantages of the utility model and feature energy
It is easier to be readily appreciated by one skilled in the art, to be more clearly defined the protection scope of the utility model.
Interior cold fluted drill described in the utility model for tangent plane at a kind of ladder as shown in Figure 1 with Figure 2, including bores
Axis 1 and drill main body 2, the drill main body 2 are correspondingly arranged in 1 side of auger spindle and are an integral structure setting, the brill
The setting of head 2 surface of main body there are two cutting edge 3, the cutting edge 3 helically structure setting on the mandrel of drill main body 2, and
And two respectively correspond between cutting edge 3 and are provided with chip space 4, the 2 end side of drill main body is arranged in hierarchic structure, described
Drill main body 2 is also correspondingly arranged on the plane 5 with axial angle on cutting edge 3, and the axial angle of the plane 5 is
10 ° -15 °, the spiral angle of the cutting edge 3 is 30 ° or 40 °, and 2 end of drill main body is provided with interior cold hole 6, the brill
1 end of axis is provided with the interior cold trap 7 of helical structure corresponding with interior cold hole 6.
The spiral bit of multi-ladder is in cutting due to band spiral angle, and angle generally is 30 ° or 40 °, at ladder
Cutting edge is sharp when cutting, by the ladder of the cutting edge of drill main body facet of the partial application with axial angle change
The sharpness of cutting edge, to achieve the purpose that promote the service life.
Interior cold fluted drill described in the utility model for tangent plane at a kind of ladder, the utility model structure is simple, processing
It is easy to use, by plane of the partial application with axial angle at the ladder of cutting edge, increase the rigidity of cutting edge, prevents tipping existing
As promoting service life.
The foregoing is merely specific embodiment of the present utility model, but the protection scope of the utility model is not limited to
This, anyone skilled in the art, can be without creative work in the technical scope disclosed by the utility model
The change or replacement expected, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model
It should be determined by the scope of protection defined in the claims.
